Register trouble

Hi there,

I have fitted a template into register.php, and it seemed to go well.. But I tried to register to make sure thing were OK, but I get an error & I can't seem to fix it: Fatal error: Call to undefined function valid_email() in /home/XXX/public_html/register.php on line 143

I haven't changed the codes of anything yet, so please don't ask why the code is like this. If you can fix it, Thanks very much. If you tried, then I thank you for your efforts. :D

Line: 143) : if(!valid_email($_POST['email']))

replace with

if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL))

Ermm.. it's working? Lol. Thanks Djkanna. Much Appreciated. :)

Danny696 · June 7, 2010

suggestion:

Replace

$IP = ($_SERVER['HTTP_X_FORWARDED_FOR'])

? $_SERVER['HTTP_X_FORWARDED_FOR']

: $_SERVER['REMOTE_ADDR'];

with

$IP = $SERVER['REMOTE_ADDR'];

Djkanna · June 7, 2010

$IP = $_SERVER['REMOTE_ADDR']; :P You made a typo

Danny696 · June 7, 2010

Ahh, my bad
