Warning: Wrong parameter count for array_key_exists() in /home/content/i/n/t/internetknight/html/register_new.php on line 172

 

Code for warning 1:

// Set pattern matching for user
		$u_regex = "[A-Za-z0-9_]{6,20}$";

		// If username has between 6 and 20 word characters
		if ( preg_match($u_regex, $user)) {...

 

Code for warning 2:

	if ( array_key_exists($error)) {..

 

What did I do wrong?

For the second error (as for the regex i know nothing), array_key_exists() takes two parameters, the first is the key to search for and the second is the actual array.

1.) The syntax of your regular expression is for use with ereg()

Try:

		$u_regex = "^[A-Za-z0-9_]{6,20}$";

		// If username has between 6 and 20 word characters
		if (ereg($u_regex, $user)) {...

 

Notice i modified your expression slightly. You'll need the ^ to make sure the match is for the entire string. With your previous expression, someone could have put any characters at the beginning of the string, so long as the last 6-20 where alphanumeric or underscores.

2.) Again, the manual is your friend: www.php.net/array_key_exists

 

The function requires two parameters, the first being the key you are looking for, the second being the array in which you are searching.
