I was making the profile picture thing! Like...Uploading a profile picture and all!
It Always Shows "Your profile picture must be an image." even though I upload a picture!
Here are my edit_profile.php script!

}
if (preg_match('#^[a-z0-9]+$#i', $_POST['location']) === 0) {
$errors[] = 'Your location must only contain \'a-z\', \'0-9\' and spaces.' ;
}
if (empty($_FILES['avatar']['tmp_name']) === false) {
$file_ext = end(explode('.', $_FILES['avatar']['tmp_name'])) ;
if (in_array (strtolower($file_ext), array('jpg','jpeg','png','gif')) === false) {
$errors[] = 'Your profile picture must be an image.' ;

Re: Profile Picture Question!
[syntax=php]$file_ext = end(explode('.', $_FILES['avatar']['tmp_name'])) ;[/syntax]
You need to use $_FILES['avatar']['name'] here. tmp_name contains the temporary name of the file on the server which does not have a file extension usually.

Re: Profile Picture Question!
It still doesn't work! 
And When I Go to ..../profile.php?uid=098347
It just shows the profile...even if there is no user with that id.

Re: Profile Picture Question!
[syntax=sql]WHERE `user_id`= ($uid)[/syntax]
You should not have the brackets around $uid on this line
[syntax=php]file_exists("{$GLOBAL ['path']}/user_avatars/{$info['id']}.jpg")[/syntax]
$GLOBAL should be $GLOBALS and you don't want that space there. Also you are trying to use the users id, when you haven’t selected it from the table.

You should not be hiding notice level errors, they often show up problems that are otherwise hard to find, for example they would have highlighted the above.
