I have a user registration form and I know how to submit the data to MySQL but before the data gets submitted I want to check and see if the username they entered is already taken. I can do this in asp/vbscript but I’m lost here.

$USERNAME = $_POST[‘username’]

$_SQL = “SELECT USER_NAME FROM MEMBERS WHERE USER_NAME='” & $USERNAME & “;”

If EOF Then
*//Code if username not taken
Else
*//Code if username is taken
End if

This is very generic so you get an idea of what I’m looking for. Can anyone help?? ?

@bokehApr 18.2006 — [code=php]<?php

#assume DB connect here

$query = "SELECT USER_NAME FROM MEMBERS WHERE USER_NAME='" . $USERNAME . "'";
$result = mysql_query($query) or die(mysql_error());
if(mysql_num_rows($result) > 0)
{
# username in use
}
else
{
# username not in use
}

?>[/code]Don't forget your variable names, column names and table names are case sensitive! Are you sure MEMBERS , USER_NAME and $USERNAME are upper case?
