you need set POST

xmlhttp.open("GET","test.php?q="+str,true);

You are in any case receive a response.

this.value = "submit" you realy need it?

<input type="button" name="submit" value="submit" onclick="loadXMLDoc(this.value); return false;">

If I understand you correctly...

<html xmlns="http://www.w3.org/1999/xhtml" lang="<?php echo get_page_language($language); ?>" xml:lang="<?php echo get_page_language($language); ?>">

<head>
</head>
<body>

<?php

$res= mysql_query("SELECT id,imageid,name,size,type from images where uploadeddate='07/21/2010' LIMIT 2");
$i = 0;
while( $row = mysql_fetch_array( $res ) )
{
	if( $i == 0 ) echo "<table>";
	$i++;
	echo "
	<tr>
		<td><a href=\"#\" onclick=\"loadXMLDoc(".$row['id']."); ?>)\">".$row['name']."</a></td>
		<td><a href=\"#\" onclick=\"loadXMLDoc(".$row['id']."); ?>)\">Description: ".$row['type']."</a></td>
	</tr>";
}
mysql_freeresult($res);
mysql_close();

if( $i > 0 )
	echo "</table>";
?>

</body>
</html>

yes, i need this.value="submit" because i am having many button values. if i press submit button then i need all the table values inserted into database.
I am posting the code to the same page(test.php).Everything is in the same page...
