any help plz ???

You don't need a join when you are only using 1 table.

$sql='SELECT car_number FROM cars WHERE car_quantity = '.$q.' OR customer_name = \''.$cname.'\'';
$result = mysql_query($sql) or die (mysql_error());

should do just fine.

plz go to here http://mwlobby.0fees.net/test/movement.php and you will find what i need

 

 

add this at your second line in ajax.php (just after $q = $_GET['q'];) :

if (empty(trim($q))){
$append = '';
}
else{
$append = ' AND car_quantity = '.$q;
}

and change the query to read :

$sql='SELECT car_number FROM cars WHERE customer_name = \''.$cname.'\''.$append;

 

is that more what you are looking for?

sorry i make the change you said but

it's doesn't work too

 

ajax.php

<?php
$q=$_GET["q"];

if (empty(trim($q))){
$append = '';
}
else{
$append = ' AND car_quantity = '.$q;
}

$cname=$_GET["cname"];

$con = mysql_connect('sql100.0fees.net:3306', 'fees0_5265972', 'kemoaly');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("fees0_5265972_test2", $con);

$sql='SELECT car_number FROM cars WHERE customer_name = \''.$cname.'\''.$append;

//$sql="SELECT car_number FROM cars WHERE car_quantity = '".$q."' AND customer_name = '".$cname."'
//";
$result = mysql_query($sql) or die (mysql_error());

echo "<select name='user'>";
while($row=mysql_fetch_assoc($result)) {
echo "<option value=".$row['car_number'].">". $row['car_number']."</option>";
}
echo "</select>"; 
mysql_close($con);
?> 

seems like the if(empty... is wrong, flings up an error when I run the script on my server.  change it to

if(trim($q) == ''){

also at the verry top of the page add this line of code

<?php
error_reporting (E_ALL);
//...

this should help with any other errors in the php.
