PHP :: How Could I Paginate The Result Set?

Displaying Result 1-8, Then Result 9-17 Etc.
I dispaly the results from the database like this.

<? while ($row = mysql_fetch_array($prod_result)) {
$small = $row[0];
echo"<td align=center><img src="produkter/hardware/decks/$small"></strong></td>";}?>

But if there are more than 8 results, I wnat to dispaly the first 8 on one page, then the next 8 on the next page...How can this be done?

Nesting Result Loops Within Result Loops Possible?
I'm looping through a query, and inside the while result output, I am trying to loop through a second query (created from the 1st query's row results).

I have checked that both queries return info.

I can see that the 1st while result output works fine, but when I get to the inner while result output, it never returns any rows (nothing in the while loop evaluates).

So, IS it possible to nest one query's output loop within another, or am I doing something wrong?

SQL Last Result
When querying and doing a loop I want to specify that the last result of the loop does not include a horizontal line. How would I do this?

Outputing Result Once Only
Hi,

I have a php script that looks up mysql records, on the basis of keywords entered by the user.

The records are in tables making up a message board system, and the search works both for 'top-level' messages, and for replies.

The results lists the 'top-level' message (ie the entire thread), even if the search matched text in a reply.

However, I am having a problem making sure the thread is not listed more than once if the search matches several replies in the same thread.

At the moment, the search looks up all the rows containing the search text, then the message starting the thread if the search has matched a reply, and the results are output in a while loop. I have tried making a long string containing all the id's of the displayed rows, usingsomething like $displayed .= _$row[id]_ in the loop, and then ereg("_$row[id]_", "$displayed", $array) earlier in the loop to see if this message's thread id is already listed, and skipping it if it is.

However, I can't seem to get this to work. Also, this seems like a really inefficient workaround. Is there a better way to do this?

Result Using Two Variables
Probably a real simple solution but I can't for the life of me work it out.

I have:

$pollitem_1
$pollitem_2
$pollitem_3
$pollitem_4

if I do a for loop for the amount of items, is it posiible to have a variable for the number after the _ ?

e.g....

Weird Result? Php 4.4.0
I have a variable v with the value -1. After v++ it has the value "" not
0. Since I am using it for a subscript, the "" value is not overwriting
the 0 element of the array as desired. Should v++ ever give a
non-numeric value?

Getting Result From Mysql
I am using this code to get some data from a mySQL database. Which seems pefectly valid to me. Here it is: Code:

To Display Nothing If Result Is None
Below is the script for displaying the data from a table. Is it possible that if there is no data, then the whole table should not display and not only the result field. Code:

Result Set Problem
I am new to programming in PHP however, this should be a pretty
straight forward answer. I have three queries that I am pulling for a
content form page.

1) The Author List
2) The Content Page (pulls the PK, Title and the Description of the
content.
3) The Category List

When I attempt to pull the data the only result set I get back is from
the Item #1 query above. Now, I made sure that there is data in the
tables, but I still get no data back for the other two queries(????)

Is there something that I missing when connecting to PHP/MYSQL? Do I
need to take some additional steps??

Any help would be greatly appreciated. I've been struggling with this
problem for several hours now scratching my head why this is.

:-)

// here is the PHP Code I am using

<?php
$db = mysql_connect("$DB_SERVER", "$DB_SERVER_USERNAME",
"$DB_SERVER_PASSWORD");
mysql_select_db("$DB_DATABASE",$db);
//result set 1 - get members
$result_M=mysql_query("SELECT * FROM tblMembers",$db);
$myrow_M=mysql_fetch_assoc($result_M);
//result set 2 - get content ID
$result_C=mysql_query("SELECT * FROM tblContent WHERE
contentID=1",$db);
$myrow_C=mysql_query($result_C);
//result set 3 - get categories
$result_Cat=mysql_query("SELECT * FROM tblCat",$db);
$myrow_Cat=mysql_query($result_Cat);.....

Oracle->not Same Result From Php And From Sql*plus
Here is my query, ran from oracle sql*plus:

SELECT mrbs_room.id, start_time, end_time, name, mrbs_entry.id, type
FROM mrbs_entry, mrbs_room
WHERE mrbs_entry.room_id = mrbs_room.id
AND area_id = 101
AND start_time <= 1076068800
AND end_time > 1076065200

Here is the correct result :
SQL> Connected.

ID START_TIME END_TIME NAME ID T
---------- ---------- ---------- ---- -- -
82 1076065200 1076068800 test 41 I

Ran from php, I got this :

ID START_TIME END_TIME NAME T
---------- ---------- ---------- ---- -- -
41 1076065200 1076068800 test I

the two ID fields are named with their table name, but php keep the second
value and display it as the first one.

Paging Through Result Set
Using PHP to query a MYSQL db, I am attempting to portion the result set on multiple pages. I see this technique used on this site. example: If a user query yields 30 results I want to display 5 results at a time allowing the user to page forward or back through the results.

I'm getting an error which get's reported something like "can't save result handler blabla".. .. i didn't note the exact error at the time and i can't bring it back cuz i deleted my whole database and started from scratch.. anybody know what this is about?? i'm pretty sure it's something to do with mysql.. it shows with mysql_error().

Search Result Help
I am trying to do the following with my search script that looks for records
in a mysql table. The following is an example of what I am trying to do.

Text being searched:

It was hurt so it jumped backwards and fell on its!

The word we're searching for "web".

The results should look like

Are there any functions out there that will do this? Or what would it take
to make one?

I have a small problem with PHP and MySQL. I want to know how to check if a value is existing in a MySQL database using PHP. The code is below: PHP Code:

Result Sets
I am having alot of trouble trying to append a result set using a loop. I am taking a number from options from a select option list in a form and for each of these i want to execute the statement.

for($y=0; $y<$totaltown; $y++) {
$result=select statement}

and then out put the info using a while loop. My problem is the result set keeps overwriting itself until it produces 0 results. I have tried using $result+=$result but it is then no longer a ersult set. The code i have works fine when i only want to produce all hte results on one page but i am paging the results which is where my problem lies ie LIMIT.

Incorrect Result
i try to insert a text in a database (mysql)

Add Sql Result To An Array
I am trying to add the results of a query (specifically a particular field's value) to a new array. The result is either an empty array or the last row in the query result instead of all the rows. Code:

Maths Result...
I have a mathematical calculation, and for some reason if i put "1" into the input this is the result i get :

Quote1 Muscle Building sessions giving you a strength gain of 4.99999999999E-5.

I have put a script in to cut the decimals so that it'll only go as far as 5 decimals but it still keeps coming up...

$DecimalRemovalStrengthresult = number_format($GainTotalStrength,5);
$DecimalRemovalStrength = number_format($NewStrength,5);
That is what im using to strip the number down so it should only show "4.99999"

If i don't put "1" and I put say anything above 1 it'll work fine and only show a figure of 5 decimal places such as 4.99000.

So what is actually happening to the number to come up with 4.99999999999E-5 ? Does the value mean infinite number or something else?

I'm trying to list out songs of a specific album and I think my code is fine. The only problem is that all the songs are displayed seven times. Everything else is fine.

Another Invalid Result Resource
Sorry to ask a debugging question, but I've been fooling with this thing all day, and I can't see what the problem is. $query is passed from search form:

Can I Parse A SQL Result As A Php Include?
I'm trying to use a MySQL database as a repository of common classes and functions, and would like to be able to get the resultant string, addslashes, and then actually execute the string as if it was an included file. I can do this by writing a temp file, then including it, and then deleting it, but any speed benefits are lost. Is there a way to actually parse the results as if they were an external include file? Thanks for the help.

Weird CURL Result
I am having a problem using curl and when it returns the page it has all of the images listed as local files to my server, I am assuming this is because the design of the site I am accessing, but shouldn't cURL recieve the site the same way a browser does and not show files local to me. I can adjust it using string replace methods but it seems a bit troublesome to do so:

MySQL Result Resource
I want to build a function that, depending on the input, will either return the results from a MySQL query or do something else and return one of several messages.

To Free Mysqli Result Or Not
In php documentation there is this note about mysqli_free_result():
Note: You should always free your result with mysqli_free_result(),

With the similar non-mysqli function there is this note:
mysql_free_result() only needs to be called if you are concerned about...

Returning 1 Result From MySQL
I know the usual way of receiving results from MySQL, useing a while loop e.g.

$sql = "SELECT * FROM users WHERE email='joe@hotmail.com'";
$result = mysql_query($sql,$connection);
while ($row = mysql_fetch_array($result)){
echo $row["firstname"];
echo $row["lastname"];
echo $row["email"];}

BUT, if I know they only 1 result is going to be returned, is there a way to do this without using a while loop? So if I only wanted to get only the firstname of the person with email joe@hotmail.com. can I do this without a while loop or do I have to use one?

Getting Result From Diff Tables
I've got several tables in my database which are all named table_1 , table_2, table_3, table_4, and so on. each table is built up like this:

user | points |

How would I get the sum of the points from all tables together for each user and them order them by that sum?

Strange Math Result... 1-1= -1 ???
See something weird on this result?

632.35 - 632.35 = -1.13686837722E-013

If anyone has seen something similar, please let me know!

this a part of the code:

$total_due = abs( $order_total ) - abs( $total_paid );
echo( $order_total . " - " . $total_paid . " = " . $total_due );

I've added the abs() in order to be sure that I'm dealing with
numbers, I've also used is_numeric() and confirmed it.
The echo() is showing the result I pasted up there.

Paginating Result For Two Queries
My page pagination works fine, but the code is just messy. Because I have two queries, one based on getting the ID number ($_GET['ID']) and one based on searching by keywords ($_POST['keyword']), I almost have duplicate codes for both.

For example,

if($start!= 0) {
if($browse) { //for $_GET query
echo 'Previous</a> ¦ '
}
else { //for $_POST query
echo 'Previous</a> ¦ '
}
}

I am not putting the full version of codes down as that would be too much. But hopefully, you'll get what I mean. I have to list "echo 'Previous</a>' twice because one's for the get query and the other's for the post query. So a lot of duplicate codes. How could I shorten the codes a bit?

Paginating Result Sets
First attempt at doing an exercise on paginating result sets

When I run the code, I receive the error "Fatal error: Call to
undefined function: mysql_fetch_objects() in
/homepages/17/d23395818/htdocs/en/test.php on line 48"

Line 48 is while($row = mysql_fetch_objects($result)) Any ideas?? Have
I missed an obvious mistake. (full code below)

<?php
//sets number of records and ref number in database to search by
$records_per_page = 2;
$search = "123-456-BSE";

//look for starting marker
(!$_GET['start']) ? $start = 0 : $start = $_GET['start'];

$connection = @mysql_connect('???', '???', '???');
if (!$connection) {
echo '<p>Unable to make database connection.</p>'
exit();
}

if (!@mysql_select_db('???')) {
exit('<p>Unable to locate database.</p>');
}

//create and execute query to count records
$query = "SELECT COUNT(*) FROM schott_news WHERE userID='$search'";
$result = mysql_query($query);

//get total number of records
$row = mysql_fetch_row($result);
$total_records = $row[0];

//if records exist
if (($total_records 0) && ($start < $total_records))
{
//create and execute query to get batch of records
$query = "SELECT userID, username FROM schott_news WHERE
userID='$search' LIMIT $start, $records_per_page";
$result = mysql_query($query);

//iterate over record set and print data
echo '<table border=1 cellpadding=10>'
while($row = mysql_fetch_objects($result))
{
echo '<tr>'
echo "<td>$row->userID</td>";
echo "<td>$row->username</td>";......

Passing Result To New Page.
I have a search result with a link which links to the ID# of the record. By clicking on the link I would like the rest of the record displayed. What will my script look like to pull a particular record ID?

Testing For Emtpy Result.
I'm working with a bit of a messy query but I'm not looking for tips
on improving it (it's been a headache enough, haha).

Basically, my site posts articles written by multiple authors. In the
past we'd associate these articles with a user_id referring to the
"Multiple" author, but now writers want their own writing within an
article to be linked with them.

This led to me splitting the article table in two: we have
review_index which has all the generic/global data for the article
(band name, record label, etc), and review_pages which has a (non-
unique) field review_id which links to the id row in the review_index
table. With me so far?

The form I wrote for admins to post multiple author reviews works like
this:

- asks them for global variables and inserts them
- asks them to add a review and select username for an author
- upon submitting this, offers them to post another (still associated
with the original globals) or lets them close the job.

It's done in this way because in order to associate the review_id with
the id field, I have to KNOW what the id field in the review_index is
going to be. I can't just +1 to the most recent one, since this'll
cause issues if we delete reviews etc.

So what this means is, when a user clicks onto an article while we're
in the process of posting it, they may load a page with all the
globals in place, but none of the actual content. I'm trying to echo a
simple "Please reload the page in a few minutes" message, but can't
get a working result. I've tried variations on:

if ($review_text = null) {
echo "come back soon!";
}

if (empty($review_text)) {
echo "come back soon!";
}

if (!$query_result) {
echo "come back soon!";
}

but none of these display. Is there a solution here? It's a trivial
issue really since it's essentially catering to people who click on an
article within a 1 minute or so period, but still.

Total Result Php Mysql
PHP Mysql
limit the result to 5
I can display the 5 results using a do & while which it ok.

I want to list the total or all the results without using a do or while

this is so I can combine the results and remove duplicate words from the
total results

I.E.
Do & While
row result
1 this is the top
2 this is the bottom
3 this is the middle
4 this is the end
5 this is the finish

This is what I want to do:

this is the top this is the bottom this is the middle this is the end this
is the finish

modified result::
this is the top bottom middle end finish

Passing A Result Set By Reference
I have a question regarding passing a result from a database query to a function as a reference. I basically want to know if passing by reference in PHP 4* is quicker than not passing by reference.I have tested some, but it will still be a bit before I'm ready to test with enough data to matter, and I also have noticed that some people have offered differing opinions regarding this.
