Hello,
Recently users have been registering with a lightning bolt, skulls, etc. I tried to fix it, but for some reason, they still can.

Here's my class.users.php code:
HTML: 
    /*-------------------------------Checking of submitted data-------------------------------------*/
    
final public function validName($username)
{
    if(strlen($username) <= 25 && preg_match("/^[a-zA-Z0-9]+$/", $username))
    {         
        return true;     
    }             

    return false;
}

Problem is fixed by not using a CMS made in 2010

        if(strlen($username) <= 25 && ctype_alnum($username))        
         {
            if(preg_match("/^[a-zA-Z0-9]+$/", $username) == 1) {
             return true;
            }          
         }                
       
         return false;    
    }
ctype_alnum is a function in php that will test if the string contains only letters and numbers. The preg_match is another check for validation to be 100% sure :)

If you're simply not going to help, this is really a basic question tbh and I see no ignorance involved in this post; so if you are going to not help then don't bother replying.

That doesn't seem to fix the problem, I can still register with a skull, lightning bolt, etc.

Try adding this to your register page.
<script>
$('input').on('keypress', function (e) {
if (/^[a-zA-Z0-9\.\b]+$/.test(String.fromCharCode(e.keyCode))) {
return;
} else {
e.preventDefault();
}
});
</script>
then to disable copy and paste add this
<script>
window.onload = function() {
var myInput = document.getElementById('username');
myInput.onpaste = function(e) {
e.preventDefault();
}
}
</script>

REMEMBER: Put these before <body>
