[Resolved] How to Make Error from Str.

[Sayian]

If i want to block username's from being created .. how can i modify this code to make it to where username's contain certian words are blocked.

if ($cusername==1)
{
	if(strlen($signup_username)<4){
		//echo " un must >=4   ";
		$signup_error = 1;
		$username_html = "<br>Your Username must be at least 4 chars";
	}
}

Thats a command that checks to see if username is greater ther 4 char , but thier should be way to make to where it can check for bad words too right?

A simple way to go about it:

// Make an array of bad words:
$bad_words = array('darn', 'heck', 'poop');

// If you don't want a bad word buried inside a username:
foreach ($bad_words as $word) {
    if (strpos($signup_username, $word) !== false) {
        echo 'not allowed';
    }
}

// If you just don't want username == a bad word:
foreach ($bad_words as $word) {
    if ($signup_username == $word) {
        echo 'not allowed';
    }
}

// Edit:
// Not the way I meant to do the second one.
// Here's a better way:
if (in_array($signup_username, $bad_words)) {
    echo 'not allowed';
}

Of course, it's easily defeated. Here's a tutorial on the subject.
