Magic Quotes

[callumacrae]

I'm trying to make a pastebin, how do I disable magic quotes?

I'm obviously on x10hosting shared hosting, so I dont have php.ini access. php.net says theres some code that can be added to htaccess, but that just made a 500 error. I don't want to have to remove the magic quotes in my PHP script, thats not really very efficient.

What are my options?

The topic has been covered many times before. The short version: you can't disable magic quotes on the free hosts (if that's where your site is), you can only undo them (which should have minimal impact on response times).

<?php // normal_quotes.php. Include this once in any script that needs magic quotes undone
function stripslashes_nested(&$v) {
    if (is_array($v)) {
        return array_map('stripslashes_nested', $v);
    } else {
        return $v = stripslashes($v);
    }
}

if (get_magic_quotes_gpc()) {
    foreach (array('_GET', '_POST', '_COOKIE', '_REQUEST') as $k) {
        stripslashes_nested($GLOBALS[$k]);
    }
}

I'm on staffserv, but I still can't disable them XD

I worked out that after I had disabled them, WordPress was adding them instead. WordPress has a function built in to remove them:

$_POST = stripslashes_deep($_POST);

It's stupid enough that PHP does it, but even more stupid that WordPress does it, but I guess it's fixed now

That sounds familiar. How do you feel about patching wp-settings.php?

Thanks, that's just what I was looking for :D Do you know why wordpress adds the quotes? I dont want to end up breaking something by editing the core.

That's what everyone wants to know, and there isn't an answer, as far as I can tell. Others have removed magic quotes with no ill effect, though it's possible that some plugins (or even the core) rely on magic quotes to sanitize data. Only a code audit could tell for certain. You could run an automated tool against your site to test for vulnerabilities, though this might cause an HRU suspension.

I'm on staff server, I don't think we have them HRU suspensions.

Thanks for your help, I'll experiment
