Neverside

neverside registering and subdomain

Hey,

I'm trying to acheive user profiles, like you have here eg. username.domain.com

I'm going to use SMF as my member base and forum, and my own gallery script, both work perfectly

My question is related to this:
Because your neverside account will comes with a .neverside.com subdomain (Unavailable at the moment), we have to restrict the characters you can use in your username. You may only use letters, numbers, the underscore (_) character and the hyphen (-) character. Also, you may not use underscores or hyphens as the first or last character of your username, and you may not use adjacent ones.

How do you detect:
1. Underscores or hyphens at beginning or end (and remove them?)
2. Adjacent underscores/hyphens
2. How to remove anything that isnt a underscore, hyphen, number or letter?

Thanks!

I'd say pass the entry data through a function, like so:

PHP:

<?php

function boldme ($text)
{

$search = array(
'#\[b\](.*?)\[/b\]#' //this finds [b] text [/b]
);

$replace = array(
'<b>\\1</b>' //this replaces it with <b> Text </b>
);
return preg_replace($search , $replace, $text);

}

?>

I know that isn't what you're looking for exactly, thats just the method, I took that from my BBCode filter function. Just search for erroneous characters and replace them with ones that work. Or you could send back to the user that you can't have those certain characters, and force them to try again.

Theres probably a better way to do that, but I've never done anything like that, so I can only give you a suggestion.

Hope that helped, good luck.

PHP:

<?php

$finds = array('/[^a-z0-9_-]/i', '/(__|-_|_-|--)/', '/^([_-]+)/', '/([_-]+)$/');
echo preg_replace($finds, '', $username);

?>

Err... We can use underscores as the first character. For example, me!

No we can't, remember I changed yours individually. You are the special one with it like that.
