hi,

i have a problem to display my data. i have 4 table (proposals,quotation, po,simulation), in proposal there is pro_id, pro_name,file_name and file, in quotation there is pro_id, quo_name, file_name and file, in po there is pro_id, po_name, file_name and file, in simulation there is pro_id, simul_name, file_name and file. ** only the pro_id of each table is the same while others such as (file_name and file) have different value for each table.

i want to combine the 4 tables but only display file from table quotation,po and simulation while table proposal will display all. is it possible?

eg:

display- pro_id,pro_name,file_name,file(form table-proposals),file(from table-quotation),file(form table-po),file(from table-simulation)..

please help..i have try so many things but still did not work..

my code :

<?php

//open connection

$connectdb=mysql_connect("localhost","root");
if(!$connectdb)
{
die('Unable to connect to server:'.mysql_error());
exit;
}

//select database

$selectdb=mysql_select_db("custech", $connectdb);
if (!$selectdb)
{
die('Unable to select database custech:'.mysql_error());
exit;
}

if (!isset($_POST['levelbox']))
{
    //Instruction if $_POST['value']doesnt exist
    $_POST['levelbox']="%";
}

$levelbox = ($_POST['levelbox']);

?>


<form method="POST" name="frmSearch" action="quotationlist.php">
<center><table width="900" border="0" cellspacing="0" cellpadding="0">
   <td width="70%"><p>
   <select name="levelbox" class="inputbox2">

    <input type="submit" name="cmdSearch" value="Search">
   </td>
  </tr>


</table> 
</form>

<?php
// Before using $_POST['value'] add this - to avoid error on undefined index

if (!isset($_POST['txtSearch']))
{
    //Instruction if $_POST['value']doesnt exist

You've made life difficult for yourself by using the same field name for fields that can contain different values. I am referring to file_name and file. If you put a prefix on these, so you can tell which table it's coming from, you could then just select the whole lot in a single SELECT statement. This would be constructed differently depending on some factors, like for example, which is the "top" table, and can the other tables contain multiple items, all connected to the same pro_id.

Did you write this code? It's very unorganized. Are you connected to the database? You already have a JOIN? In your case, you want to merge 4 tables and in order to do that you need a JOIN which you have already. This very complicate to print columns from different tables.
