Perhaps it is a language issue, but the way you word your question is like an order. People on these forums are here by their free will and their own time.

Ordering is likely to be ignored.

<?php
Try this :

if($count !== 0)//Record is present!
 
{
 
die("<h2>ERROR: The Username is already taken!</h2>");
}

Also you need to protect your from field imo... You have form fields that can be 1 char long, or 560 char long, also you do not sanitize them before DB input. This all needs to be done unless you want a possible security hole in your web app. ;)

Wow, I can't believe I missed that :[

$username isn't set to anything....

$username = mysql_real_escape_string($_POST['username']);
$namecheck = mysql_query("SELECT username FROM personal WHERE username ='$username'");

Just echo your count value and see the result

echo "count=".$count = mysql_num_rows($namecheck);

karthik_ppts 81 Posting Pro · Answer 4 · 2011-05-25T15:14:20+00:00

$namecheck = mysql_query("SELECT username FROM personal WHERE username ='$username'");

Where did you pass the value for $username?
