preg_replace - Exclude Text in Search Code Line - Posts Image Replacement Not Smilies

[Deceptor]

I agree with Dismounted, however as a temp solution here you go:

PHP Code:

if (!function_exists('check_image_src'))
{
    function check_img_src($tag, $src)
    {
        static $blacklisted;

        if (!$blacklisted)
        {
            $blacklisted = array(
                'website1.com',
                'website2.com',
                'website3.com',
            );
        }

        foreach ($blacklisted as $bl)
        {
            if (strstr($src, $bl))
            {
                return '';
            }
        }

        return stripslashes($tag);
    }
}

$this->post['message'] = preg_replace("#(<img src=\"(.*[^\"])\" border=\"0\" alt=\"\" />)#e", "check_img_src('\\1', '\\2')", $this->post['message']); 


I would not recommend using this long-term, just adjust the array in the code to add additional websites to the blacklist. Your smilies should be unaffected even if you block your own forums domain.
