Table Display Grouped By Specific Field


I operate a youth sports website and i display my current alignments in a long running list of teams (one field within my table) with association divisions (another field within table).

I would like to group them by divisions, like a two column table for better clarification.

What Is The Best Way To Display Specific Info From A Table?
I am hosting a youth sport site and I want to display schedules by select teams.

I thought that I would want a drop down menu to select one of our 35 divisions, then a secondary search by team of that previously selected division menu.

My schedule is in a table with the fields:
* division
* date
* time
* home_team
* h_score
* visiting_team
* v_score
* field

I see problems, since secondary drop down menu would have to search two different fields.  Any suggestions and hint to where I would even start?

Counting A Specific Id To Display
i have constructed a forum (very basic) i have 2 main categories , 1 has id 1 and the other 2.

once a topic is posted within these categories a 1 or a 2 is stored into `topic_id` which is in `forum_topics`

so if i post in category 1, a 1 is stored into `forum_topics` as a way of tracking the different categories that are added later, my problem is when i put my pagination in for the sections, (it displays the correct number of links for each section) but still shows me all the posts, the links are right but it still displays the posts on the 1 page Code:

How Do You Display SPECIFIC File Types In A Directory On A Web Page Please?
Hello,

I have the following code:

<?php
$handle = opendir('images/');
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "<a href="images/$file">$file</a><br>";

ECHO The Amount Of Rows In My Table According To A Specific Username
I am creating an infinite loop with this code. My goal is to just ECHO the amount of rows in my table according to a specific Username. How do I do this? my code:

<?php $query = "SELECT ID FROM products WHERE Username = '{$Username}'"; 
$result = mysql_query($query) or die(mysql_error());
$row = mysql_num_rows($result) or die(mysql_error());
$num = 0;
while ($num <= $row) {

Display Only Field...
how can change this field, a text box, to a display only(non-editable field) in php?

                        <td width="196" height="22"> <div align="right"><font class="inputLbl">Date:&nbsp;&nbsp;</font></div></td>
                        <td width="130"> <input name="datebox" class="txtbox" value="<?

is it possible to make datebox a display only field? i dont want users to be able to enter invalid dates here. they should only be able to enter date from the datebox feature(a calendar pop-up). that feature works with all validations in place. its only when users enter (manually type) a date in the text box that valiations dont work(for instance, 05/32/2007 is taken as a valid date!)

i want to change the datebox field to a display only field.

Limit A Database Field To Displaying Only One Time And Still Display All?
I have a data table with a field that contains the exact same text (example "some text") on several different rows. How can I display all my rows without getting duplicates of this field; I only want to display this field once. I tried to use a LIMIT, but this is not what I needed. Code:

Getting Field Count From A Table.
I've searched through devshed but haven't found a reference to how to query a database for the contents of a table, then count the number of fields in that table. Can someone help?

Say, for instance, the call was FileName.php?table=Vendors

In FileName.php, once you'd done all the happy connect stuff,

$result = mysql_query("SELECT * FROM $table",$db);

how would you count the fields in the result, regardless of the number of rows?

I thought I could use mysql_fetch_row($result), then, with a single row selected count through the $myrow[] until they ceased to exist. Is this doable? It seems this would be fairly straightforward. Is there an easier/faster/better way? I'm still thumbing through my php/mysql tomb working on the problem but haven't found an obvious solution. Your thought are sincerely appreciated.

Get Max Value In MySQL Table Field
I have a 2-field table "pageref".

The fields are: "pagerefno" - which is index and primary key, and "url".

I need to find the max value in "pagerefno", so wrote the following code:

$query ="SELECT max(pagerefno) FROM pageref";
$result = mysql_query($query) or die ("Error in query: $query. " .
mysql_error());
$row = mysql_fetch_row($result);
echo row[0];

But this results in a blank screen. I'd be grateful for a steer, here.

Nonexistant Field In Table
I have a script that updates some mysql tables using input from a text file. The query that's giving me trouble is this one:

"UPDATE $table SET `$f` = '$v' WHERE id = '$new_id'"

where $f is the name of the field and $v is the value. The problem is, some of the information in the file is outdated, so some fields don't exist anymore. If I try to run the update with a field that doesn't exist, the script halts and I get an error.

Is there any way to have the script ignore this and just keep going?

How To Get A Field In The Last Row Of Mysql Table.
There is a certain field that I wish to get in the last row (it will always be in the last row, even if I add to the table) of my mysql table. How do I output this? I assumed that I would be using a LIMIT command and a DESCRIBE command, however I looked at mysql.com and couldn't find anything .

Set Variable Name Use Field Name From Table
I have a query string that sets the value of Variables below:

if ($DB == "Departments") {
$tracking_id = $data22['tracking_id'];
$dept_name = $data22['dept_name'];}

simple and straight forward. Now I would like to set a loop that would set the variable name and value based on the field names in the table queried.

if ($DB == "Departments") {
$querystring = "Select * from ".$DB;
$result=mysql_query($querystring);
while(($field = mysql_fetch_field($result))) {
$field->name = $data22[$field->name];}}

can I set the variable name using the $field->name if so how? I have tried this code with no luck and no luck searching. This is a small example. I have queries with fifteen plus fields. This would also remove the need to modify this code if a field needs to be added to the table. And yes I have had to add fields to the tables.

ASP.NET & PHP - Php Xml Table Display
I hope that there is someone fluent in both php and asp.net who can help me bridge a gap.

In asp.net it is fairly easy to take a simple xml file and display it as a table [or datagrid], using something like:


void Page_Load()
{
String xmlFilename = @"C:...example.xml";
DataSet newDataSet = new DataSet();
newDataSet.ReadXml(xmlFilename);
DataGrid1.DataSource = newDataSet;
DataGrid1.DataBind();
}

followed by:

<asp:DataGrid id="DataGrid1" runat="server"></asp:DataGrid>

I would like to know how to do this in php.

Syntax For MIN And MAX Values Of A Field In A Table
I wish to assign a variable name to the MIN and MAX values of a field
in a table. The type is int(7).

I am extracting the field with many others with the following code
from a php call.

$ml_collect='SELECT * FROM ml_lopp LEFT JOIN scfmforening ON
(scfmforening.scfmnum=ml_lopp.scfmnum) LEFT JOIN ml_newtidplats ON
(ml_newtidplats.loppnum=ml_lopp.loppnum) ORDER BY date1,
ml_lopp.loppnum'

$ml_upg=mysql_query($ml_collect);

mysql_close();

The field is contained within the table ml_lopp and it is called
loppnum

I have been trying combinations of this to extract the min and max of
the field from the $ml_upg variable which includes all of the data to
be processed.

$lownum=mysql_result($ml_upg,MIN('loppnum'));
$hghnum=mysql_result($ml_upg,MAX('loppnum'));;

Which does not work.

Displaying Table Field List
I got a function that displays a list of the fields in a certain mysql table.  I got it off of this site.  The problem is that it only displays the word Array and I'm not sure why.  This is the code for the function: Code:

Iinsert The Auto_increment Field Into Another Table?
I have 2 tables ('customer' and 'regcustomer') and 1 form. The user fills in the form with all their details and the script should insert their credentials into the 'customer' table, which has an auto_increment field for the 'customerid'. I then want the script to take the 'username' and 'password' specified in the form, AND the 'customerid' generated in the 'customer' table and insert it into the 'regcustomer' table.

The credentials are inserting successfully into the 'customer' table and the 'customerid' is automatically being generated there. I just can't get the generated 'customerid' to insert into the 'regcustomer' table.

Here's the code that's generating the error:

$query1 = "SELECT last_insert_id(customerid) FROM customer";
$result1 = mysql_query($query1);
//echo $result1;
$row = mysql_fetch_array($result1);
$result2 = $row['customerid'];
$datapoint = mysql_result($result2, 0, customerid);

$result3 = "INSERT INTO regcustomer (username, password, $datapoint)
VALUES
('$_POST[username]','$_POST[password]','$_POST[customerid]')";

The error message i'm getting is:
Warning: mysql_result(): supplied argument is not a valid MySQL result resource in....in line 25

Line 25 is the  [$datapoint = mysql_result($result2, 0, customerid);] line. I think it doesn't like the '0' argument here as it's turned to red in my editor!

Putting An Array In A Mysql Database Table Field
I want to insert an array into my database but i've got a problem with it.

Before i insert the array into the dbase i check if everything is in the array with print_r($array). Everything that should be in the array is in there so i insert it into the dbase.

When i check my dbase with phpmyadmin the field that should contain my array has the word array in it so i assume the array is in the dbase. But when i retrieve the data from my dbase and check my array with print_r i get the following error: Warning: Argument to array_values() should be an array in.

category and the rest of the data displayed under the relevant category.

don't know how to have the records placed under their corresponding
category. This is my code thus far (sans the html output):

Dyamic Table Display For Picture Presentation
I am trying to practice good web coding technique and stay away from the dread iframes. (Just like the bogey monster under your bed when you were 5, but hidden in cyberspace =/ ) So here is an overview of what i am trying to do.  Values are sent to the Picture Window using a function. 

Corresponding values trigger images to show up in the Picture Window dynamically.  When the user clicks on pic3 the value is sent to the Picture window; this displays a larger image of "pic 3" is shown in the Picture Window.  The variable passed corresponds to the images the user clicked on.  For example the user click on pic3 a value of pic3-large.jpg is sent to the getPicture function which displays a larger image in that window.

General layout of the function is written below. The question that I have is how can I capture the user clicks to send a value to the function getPicture($image)? My next question is how can I get pic3-large.jpg to show up in the pic3 table, while keeping all other parts static? The table id for the picture viewer is picture_view. I could use an iframe but I rather do this in PHP. Since the support for iframes is rather buggy; and really isn’t a cross browser solution. Here is a picture to better explain what im trying to do and below it is some code:

Display Database Output In Mutli Column Html Table
I am building an HTML form using data from a mysql query. The data to be displayed on the form is 1 column from the db - but multiple rows. Because there are many rows (well, only about 100+) in the table I want to be able to put 2 or 3 (space permitting) rows from the result on each row of the HTML table with a checkbox beside each entry from the db table. The idea is that the user will scroll down the list and check up to 4 or 5 boxes before submitting the form and I didn't want them to have to scroll ALLLL the way to the bottom (100+ rows). I understand how to get data from a db table and put it into an html table, but I cannot figur out how to put more than 1 row from the result on to the same row of the html table.

I hope I haven't confused anyone reading this -- If I am way off base with what I am trying to do please give me alternatives. I am trying to avoid paginating the data for a couple reasons a) clicking a next and/or prev button is more hassle than just scolling down a list and b) the data in the column being displayed is only about 35 - 40 characters and it seems to be if i only placed one result row on each html table row, there would be a lot of wasted space.
