PHP :: Using Arrays With Mysql Query Results

Arrays, Query Results And Select Box
I want/need to pre-select a drop-down box with a value if it's present in both a lookup table and user account table. After wrestling with this for a few hours I give up.

i know this can't be this complicated, but apparently i'm missing something, so if anyone can suggest a way to go about this i'd be a little more sane. The idea is to have the user value already selected then when they change the value i'll update their account.

MySQL Query And Arrays
I have a 'links' category on Table A and I want to retrieve the links from the Table and display them in a list-like fashion when the page is called upon. How would I go about seperating the links from one another (there a space inbetween each link.. EXAMPLE: http://asdf.com http://asdasd.com http://asdfff.com), loading them into an array (or using the best possible method to acces them easily) and then displaying them in a list like fashion..?

Populating Arrays From MySQL Query
I have the following code: http://pastebin.com/746601

The field 'material' in 'is_material' contains multiple values for each
record in 'is_details'. Because of this I have used
'is_material_lookup' as a reference lookup table containing the
'style_code' and 'material_code' which refer to their full details in
the respective tables.

Currently I have got the script outputting all the details and one
material then in the next block of data, repeating the details with a
different material. What I would like to achieve is having 1 block of
data with a list of all materials in that, instead of the repeat, but
sadly I can't know exactly how to do it.

Exploding Results Of Mysql Query
I have a table with times and dates listed like this:

0000-00-00 00:00:00
2003-09-20 20:26:22
etc
etc

What I want is to query the DB for the field (matchdate) and then get it to explode the ' ' to give jsut the date for me and then put it into a dropdown in a loop. this may sound easy but i too sleepy to work it out and searching aint good.

MySQL Query Not Returning All Results
I have a user table in the DB, for example:

+---------+----------------+-------------------+
| uid | username | firstname |
|----------+----------------+------------------+
| 1 | cobby | Andrew |
| 2 | admini | test-account |
+---------+-----------------+------------------+

If, in phpMyAdmin, I query:
SELECT `username` FROM `users`;

It will return results correctly (cobby and admini, respectively).
But if I make a simple PHP script, such as:

<?php

mysql_connect('localhost', 'cobby', 'dbpass');
mysql_select_db('testdb');

$query = mysql_query('SELECT `username` FROM `users`');
print_r(mysql_fetch_assoc($query));

?>

It only returns:
Array ( [username] => admini )

Why does it only return the second result? I have a feeling I'm doing something really silly, but I looked over this test script and its got me stumped.

Possible To Create A Variable From The Results Of A Mysql Query?
I need to perform a mysql query,Take the results and create a loop for each item that returns, and then create a variable that will pull the complete results from the query to include into a template. here is the code I am woring with PHP Code:

Caching MySQL Search Query & Results
I'm developing a site that may eventually have a very large database of
users (hopefully, but who knows). It will be a community website where
users can search each other (think Friendster, Classmates, every dating site
out there, etc.).

Often there will be queries with multiple joins and sometimes may include a
few fulltext searches. Each page of results will have a limited number of
results displayed (obviously). As I understand it, MySQL caches only exact
queries, so doing a LIMIT (x,y) on each query to get results for the
specific page will cause MySQL to run the entire query again, instead of
pulling from the cache. I will limit the results to 1000, but what's the
best way to limit results per page?

I was thinking that I could run the SELECT and LIMIT to 1000, then do a
mysql_data_seek to jump to the starting row for the page and fetch a certain
number of rows for the page. For each page, the exact same SELECT would be
used and therefore the results would be cached.

Also, how should I save the search query? The users will be searching with
any number of search terms, way too many to do use GET variables. I don't
want to create a hidden form with each search term as hidden inputs (for
one, that's kind of lame). I was thinking of saving the search query to the
database, I guess I could implode the POST array into a string and then save
it in the db.

Mysql Doesnt Return All Results Of A Query
I have an sql query like this:
SELECT column FROM table WHERE column1="3" AND column2="1"
This query works perfectly if i run it in the command line, to be
exactly it return two results.
But if i run it from php i just get the first of the two results.
Any ideas?

Mysql 4.1.8
php 5.0.3

I have a second problem. But its more of a question.
if i run the foreach loop on an array like this
array("id" => "78"), then it splits 78 up in 7 and 8.
Now you say its stupid to use a foreach for this array. But in the
function there i use it the array could also be two dimensional.
Is this behavior normal? I looked in the php manual but found nothing.

Show Mysql Query Results On Pages
Does anyone have a script that will show mysql query results as paged results? This is what I have at the moment and it does not pass the results to the second page. Code:

Results Of Same Field Names But Different Tables In MySQL Query.
I have a SQL string with a couple of JOINs that works perfectly in
command prompt. I get results for all the fields selected just fine.
But when I put it into a PHP page, I can't make variables(?) out of
fields that have the same field name from different tables.
Here's the SQL statement:

$sql = "SELECT orders.companyid,orders.ordernum,orders.address,tb l_ih_accounts.company,tbl_ih_accounts.address
FROM orderstatus ".
"LEFT JOIN orders ON (orderstatus.ordernum = orders.ordernum) ".
"LEFT JOIN tbl_ih_accounts ON (tbl_ih_accounts.id = ihid) ".
"WHERE submitted <> 'yes' ORDER BY orders.ordernum ASC";

Then in the "WHILE" clause after the database is queried:
$o_address = $row[orders.address];
$ih_address = $row[tbl_ih_accounts.address];

I've tried it without the table names in the $row statements, but then
I'll just get the results for tbl_ih_accounts.address.
I'm thinking there must be some way to uniquely "name" the results of
a particular field up in the SQL statement, and then just use that
unique name in the WHILE. But I have no clue, and can't find anything
about anything like that.

Use Arrays To Page Through Results?
I've got a search facility that interrogates an SQL database then shows the results 30 at a time. Currently, when you go to the next page of results it has to run the query all over again, because there is no way of handing the resultset to the PHP file. So I wondered if there was another way of doing it.

I'm tempted to use mysql_fetch_array and create a multi-dimensional array full of result rows, then hand that around, but so far cannot find out how to hand a PHP array as a variable to a PHP page.

IS this possible, or am I barking up the wrong tree? Or is there a better way of doing this?

Is There A Quick Way To Compare The Results From Two Arrays And Note The Diffences?
is there a quick way to compare the results from two arrays and note the differences?

I have two identical tables in MySql (backup and current table) and I want to work out the differences between them (i.e. what fields are different). I could construct some long function, but I was wondering if anyone had a quick method (I am just learning PHP).

Help Needed Using Arrays In Query
I am try to use an array in a MySQL query using the in function. This requires a "," between each array entry but not at the end of the array. I can get a "," in between but I am left with one at the end. How can I get rid of the last ","?

Getting Too Many Results From A Query!
This is very peculiar -- for some reason, I'm getting 6-8 results from each
of these queries, although only one listing matches. I have a pair of forms
on one page:

<FORM>
Search for lastname: ____________ [Submit]
</FORM>
<FORM>
Search for email: ________________ [Submit]
</FORM>

This goes to a searchresults.php page:

if ($searchname !== "") {
$query="SELECT artistID,firstname,lastname,email,city,state,count ry
from artists WHERE lastname='$searchname'";
$result=mysql_query($query) or die(mysql_error("Could not execute
query."));
while($row = mysql_fetch_array($result)) {
$alt_artistID = $row['artistID'];
$alt_firstname = $row['firstname'];
$alt_lastname= $row['lastname'];
$alt_email = $row['email'];
$alt_city = $row['city'];
$alt_state = $row['state'];
$alt_country = $row['country'];
echo "<CENTER><HR>".$alt_artistID."<BR>"
.$alt_firstname." ".$alt_lastname."</A><BR>"
.$alt_email."<BR>"
.$alt_city.", ".$alt_state." ".$alt_country."<BR>
<A HREF=delete.php?aritstID=".$alt_artistID.">DELETE THIS
LISTING?</A><BR></CENTER>";
}
}

The second section is identical except for:
if ($searchemail !== "") {
$query="SELECT artistID,firstname,lastname,email,city,state,count ry
from artists WHERE email='$searchemail'";
etc...
}

I don't understand why I would get 6-8 records when you can look at them and
see that all but one clearly do not match...?

Using Query Results
Can you use a queries results only once? In this script I'm looping through a query and saving some values in an array. A little further through the script I need to use the same query for output. When I loop through nothing is echo'd to the browser. When I output a row count it shows that the correct number of records, so they must still be there.

Query About Empty POST Arrays
I started programming in PHP recently and have a query about empty
$_POST arrays. I can see two scenarios when this could happen.

1. When some tries to directly load the page to which data is being
posted (for example, opening www.foo.com/xyz.php directly when a form
action is xyz.php)
2. When the user clicks the submit button without entering anything.

I am aware that Javascript validation can take care of the second case,
but it's unreliable. What is the accepted way of handling the above
situations on the server side?
Do I just reload the calling page if the array is empty?

Query Results In 2 Columns?
I'm struggling to figure out how to do this properly. I have done a mySQL
query to extract a list of names, and done a mysql_num_rows to determine how
many results I've gotten. I want to split the list in to two columns. I've
created $percol = $mysql_num_rows/2 but I'm not quite sure how to "loop"
through the first half of the list, echo </td><td> and then list the
balance. Can anyone give me some guidance on how best to structure this?

Finding The Results Of A Query
I am working on a script that will query a database for a FNAME/LNAME
combo. If it finds the combo, I need it to do one set of instructions.
If it doesn't find it, I need it to do something else. What I can't
figure out is what variable to check against. Here is what I have for
the relevant part of the script:

$connection = mysql_connect($hostname, $username, $password);
mysql_select_db($databasename) or die ("Cannot connect to database"
..mysql_error());
$query="SELECT FNAME, LNAME FROM (table) WHERE FNAME=('$FName') AND
NAME=('$LName')";
$result = mysql_query($query) or die('Query failed: ' . mysql_error());
mysql_close($connection);

I tried checking the value of $result to see if it changed depending on
whether or not it found the selection. It does not. I just can't figure
out what to use for:

if (some expression){
perform this code
}
else{
do this
}

Grouping Results Of Query
I'm brand new to PHP (just starting today to convert tons of
ColdFusion/Access code to PHP/MySQL). There is a function in
Coldfusion that I can't find an equivalent to in PHP. Here is
what I am trying to do:

If I have a query that results in this information:
State Firstname Lastname
Idaho Terry Pratchet
Vermont Dan Brown
Vermont Bob Smith
Virginia Alice Johnson
Virginia David Jones

I would like to output the info like this:

But all I can find in PHP is a way to loop through the query
and show every row... if you are familiar with Coldfusion,
what I am looking for is something similar to this:

<CFOUTPUT GROUP='State'>
#State#<BR>
<CFOUTPUT>
#Firstname# #Lastname#
</CFOUTPUT>
<BR>
</CFOUTPUT>

Is there a function that does this in PHP, or do I need to
write code that watches the value of 'State' and manually
takes care of things whenever it changes?

ODBC Query Results
Consider the following:

<?

$username = "foo";
$password = "bar";
$host = "db";

$connect = odbc_connect("$host", "$username", "$password") or die;

$query = "SELECT id, name, address, city, state, comments1, comments2
FROM data.table1, data.table2 WHERE id = ô˜'";

$result = odbc_exec($connect, $query);

while(odbc_fetch_row($result)){
$id = odbc_result($result, 1);
$name = odbc_result($result, 2);
$address = odbc_result($result, 3);
$city = odbc_result($result, 4);
$state = odbc_result($result, 5);
$zip = odbc_result($result, 6);
$comments1 = odbc_result($result, 7);
$comments2 = odbc_result($result, 8);
print("ID: $id<br>Name: $name<br>Address: $address<br>City:
$city<br>State: $state<br>Zip: $zip<br>Comments1:
$comments1<br>Comments2: $comments2<br>
");

}
?>

Only one record is returned from data.table1 (containing the id, name,
address, city, state, & zip). However, there are multiple records
returned from data.table2 (records from comments1 & comments2). What
is happening is that when I run this script, all of the data returned
from data.table1 is printed over & over again along with each record
returned from data.table2. How can I make it such that id, name,
address, city, state & zip are only printed once - and allow comments1
& comments2 to be printed multiple times for each occurance in the
database?

I've thought about just creating a second database query for the
records in data.table2, however I need the join I'm getting by using
the existing query.

For what it's worth, I'm connecting to a DB2 database using PHP /
Apache on Linux.

I'm confused by this.

Losing Query Results!
If I make a query;

$result = mysql_query($theQuery, $db);

and then make use of the query results like so;

while ($row = mysql_fetch_row($result)) {

//do something with query results}

I can't use $result again, I have to make another query! Why is this and is there any way around it?

Multiple Sql Query Results
I'm trying to do a query from 2 databases. Basically i have
catagories within 2 databases. If both catagories return 0 rows then it
does nothing but if one or both have rows returned then i need it to
echo a result. I guess where i'm wondering if there's an OR statement i
can use or something to that effect...

something like

if($numrows == 0 OR $numrows2 == 0) {
echo ('');
}else{
echo ('$result');

SQL Query - Results From Another PHP Page ?
Can I store this PHP code in another page, then refernece it on
multiple pages using Require or Include ???

//results from sql query
for ($i=0; $i<$number; $i++) {
$ID = mysql_result($result,$i,"ID");
$CompanyName = mysql_result($result,$i,"1");
$ContactName = mysql_result($result,$i,"2");
$Phone = mysql_result($result,$i,"3");
$HomePhone = mysql_result($result,$i,"4");
$MobilePhone = mysql_result($result,$i,"5");
$AltPhone = mysql_result($result,$i,"6");
$SecondContact = mysql_result($result,$i,"7");
$SecondPhone = mysql_result($result,$i,"8");
$ThirdContact = mysql_result($result,$i,"9");
$ThirdPhone = mysql_result($result,$i,"10");
$Notes = mysql_result($result,$i,"11")

Sql Query Results And Scrolling
I make a mySQL database query and display the first 10 results. Then
the user can click on "next" link to get the next 10 results. How can
I do that without issuing the sql query again? Can I keep the results
from the first query?

Query In PHP Won't Return Results In There's Only 1
$sql = 'SELECT `PageTitle` '
$sql .= 'FROM `Pages` '
$sql .= 'WHERE `PageID` = 1 LIMIT 0, 30'

I have run this query in MySQL control panel and it works perfectly.
When I try to do it via PHP I get no results.

If I select all rows (i.e I don't specify a "WHERE") I get one fewer
rows returned than there actually are.

Tabulating Sql Query Results
I'm trying to number my rows in the column named "Pos" but so far I not getting any success, someone please bail me out find below my script, this script displays my results fine but without my Positions (Pos); Code:

Combining Query Results
I have two queries which searches for any fixtures your clan (team) is in and then returns some information about the fixtures. Is there any way of combining these results and ordering them by date? Code:

Filtering Results With Php Query
This code works, but I don't know how to filter the results to where only one person is displayed..it displays all records with similar address or state or city, I would like to know how to make it display only one person when multiple search fields are entered.

I'm using PHP5, and I have searched the forums but I'm not sure exactly if I found what I'm looking for...I don't know much about php or mysql. Code:

Capturing/using Results Of Query
I would like to display/capture/use the URL's that are displayed on a web page after making a query to a forum.
What do I mean?

I am part of a forum that uses vBulletin. One option is to display the forum topics that have had posts that day, i.e. active topics.

Essentially, when you click on the link:
http://www.somedomain.com/forum/search.php?do=getdaily

the resultant page has a list of the active topics, highlighted as links.

What i would like to do is capture/access that resultant page and use regular expressions to grab the URLs. I can do the RegEx but I cannot seem to capture that resultant page.

How Do I Show Results Of A Query
I know how to connect to a Mysql table. I want to run the query and show the results on my page. I'll have about 25 different fields I need to show on the page. Most of this information will be a couple of addresses.

Basically, a billing and then a shipping address. Can someone show me how to show some of this on a page? I'll need to align all this stuff around the page.

Filter Results Of Query
I am modifying some pages in CRE Loaded.

allprods.php list all currently active products and I added a manufacturers column that displays who makes that product.

I want to allow shoppers to filter the product list so that it shows only products from a particular manufacturer.

I have gone through several scenarios in my mind, but nothing I've thought of seems simple and bullet proof.

One of the issues is that the all products query includes all manufacturers. If I were to put a variable in the query to select only a particular manufacturer, how would I code it so it does not interfere with the all products query?

Would logic based upon the value of a form action work? If form action exists, someone wants to filter. If not form action or form action = all, then they want the whole list. Seems like filtering a list is pretty common and there should be an easy solution.

Disable Passing Arrays In Query String?
Is there any way to stop PHP from turning a query string like this: ?var[] into an array when it is read by $_GET['var']? I have quite a few input validations that are easily screwed up by this strange (and apparently undocumented???) feature...

Formatting Problem With Query Results
I have a minor problem with a script. I have written a piece of code (do...while loop) that will return results of a query a row at a time, with the proper formatting in a table. Everything works fine when there are results to lay out in the table. The problem arises when the query yields no results. When this happens, the loop below iterates once (without data) instead of not executing at all:

$result2=mysql_query("select * from ...) or die("");
$myrow2=mysql_fetch_array($result2);

do {

...bunch of stuff...

}

while($myrow2 = mysql_fetch_array($result2));

Where do we go from here?

Combining Results From MSQL Query
I have the following 2 queries which each produce a result. I have spent hours reading up and have searched devshed but I can't find how I would go about Adding these two numerical results together using PHP.

Query 1

$sql = "SELECT SUM(total) AS total_price FROM detail_tourdet WHERE voucher_id = '$voucher_id'";
$result = mysql_query ( $sql );
$row=mysql_fetch_array($result);
echo $row['total_price'];

Query 2

php $sql = "SELECT SUM(total) AS total_price FROM retail_acom WHERE voucher_id = '$voucher_id'";
$result = mysql_query ( $sql );
$row=mysql_fetch_array($result);
echo $row['total_price'];

Sorting Database Query Results
I want to know if it is possible to sort query results so that the records with a value in a certain field is displayed first and the records with the field empty thereafter.

Sorting Query Results Into Groups
I have a 'staff' table with a column 'status', corresponding to a
'statuses' table with the appropriate titles (eg 1 | Editor in Chief).
I want to display on the page the headings (the titles from statuses)
along with all of the staff members with that status ID.

I've attempted this using a query for each possible status, which I
figure was pretty inefficient (plus it didn't work properly). The best
I could do manually was to just display a list of staff and their
statuses sorted in order of the title ranks.

How To LIMIT Results In Html Php/sql Query?
I need to limit results in the following query type:

http://www.somewhere.com/php/sql-a....ql_order=&pos=1

I found a reference that says I should be able to use LIMIT x[,y], but
I don't know where/exactly how to add that to the string. Once I know
what it's supposed to look like, and can write something to generate
it.

If someone could post an example using the above and limiting the
output to 100 records starting at position.

Display Query Results In A Table
$sql = "SELECT name FROM employee_tb;
$result_query = @mysql_query ($sql);// run the query
while ($row = mysql_fetch_array($result_query,MYSQL_NUM)){
$name = $row[0];}
// assuming i have 8 results

how can i display the results from this query in a table with 3 rows each column?

Query Results And Affected Rows?
I'm doing a mass database update and I have a query string something like this:

UPDATE table SET field1=0, field2='' WHERE (email='address1' OR email='address2' {and so on...} );

I know you can view how many rows were changed after its done. I'm wondering though, is there a way I can view which entries failed? For example, lets say the email address - 'address34' was not found in the database, is there anyway I can display this from this UPDATE query? or to do this, would I have to compare each address individually with the table to check if it exists? (and if it matters I have about 1000 adresses that are being updated from this)

Query Results With Multiple Keywords
The way I have it set up now, a form results in 2 keywords, namely Keyword and Keyword2 using 1 text field, and one select field. In the text field, the person enters in the City, in the Select field, they choose a state, which abbreviates it to 2 letters.
Now, for the code that is supposed to process this: Code:

Sql Query Not Returning Correct Results
i'm using an entry in an sql database as a semaphore and it,
unfortunately, doesn't appear to be working. the script that spawns
the child processes has a for loop that performs the same basic sql
query over and over again until the value has changed (there's a one
second delay between each query). unfortunately, the resultant row is
always the same, even when the other process *has* changed it. as an
example, if the orig. value was of the entry was 0, and one second into
the execution of the second process, the entry was changed to 1, my
program would, even 10 seconds later, fetch 0. in other words, it'd
never be aware of the change.

any idea as to why this is and what i can do to fix it?

Aligning Multiple Query Results
I'm trying to pull data from 2 different tables and do a loop to
retrieve more than one row. I'm having problems with aligning the
information. Can someone lead me in the right direction? I've done some
looking myself and found something called GROUP BY? Is that what I need
to use?

Checking Lenth Of Query Results
If I return a result from a query with mysql_fetch_array and need to check the character length of a specific field, what is the best way? I have tried mysql_field_len but am getting errors with the code below: PHP Code:

I Need To Export Query Results To A .txt File.
Here's some code:

I need this info displayed on a .txt file that is updated each time that text file is called up. So if a new result is added, when that text file is called up I need that new listing to appear there. Or every time a new result is added, it updates the text file. Whichever makes the most sense, I'm not sure.

How To Truncate Multiple Query Results....
I have a news section on my website, where the article(s) are stored in a MySQL database. Titles in one column, article body in another. On the actual page, I have a limited space to which to print the content, and need to truncate it so it does not overlap, or stretch the content div and blow the design out of whack.

When only returning one article from the db, I can do this easily, however, the problem is that not all articles are/will be lengthy enough to fill the div. In such cases, I want to return the next article, up to the remaining div space, then truncate it.

For example, right now, the article that's being displayed fills up more than the allotted space, so it's truncated. But the next three articles I post may be short, where I'd need all three plus a segment of a fourth to fill the space. Using Dreamweaver MX2k4 I can do this by "repeating that region", but limiting the number of characters is only applicable to each query, not to the overall div. As such, it won't work in the way I need. Code:

I Get The Number Of Raws From A Query, But Can't See Results
I get the number of raws from a query, but can't see results?

Putting A Line Break In Query Results
Quick question, how would you go about putting a line break after a certain number of results pulled from a query? What happens is I get too many results and it stretches the page, thus looking awful. So what I want to do is print half of the results on one line, use a line break <br /> and display the other half.

So instead of results that are say....
A B C D E F G H I J K L M N O P Q R S

I want....
A B C D E F G H I J
K L M N O P Q R S
