PHP Array Help

[Dutchcoffee]

Hi,

I'm trying to use an array to pick out the "blacklisted" words from being used.

I'm currently trying to use this...

PHP Code:

$not_allowed = array("root","www","www2","ww3","admin","staff","dev","mail","web","cpanel","webmail","whm","host","ww2","members","member"); 


And to execute this, I'm using...

PHP Code:

if(in_array($not_allowed))
{
    $_SESSION['error'] = $not_allowed_error;
} 


What I want, is if anyone types any of those words in the specified text field, it will give them an error, but it's not picking them out for some reason.

Thanks.

You need the $needle part of the in_array() function.

bool in_array ( mixed $needle , array $haystack [, bool $strict ] )

So you'll do something like this.

PHP Code:

$input = $_POST['input'];
if(in_array($input, $not_allowed))
{
    $_SESSION['error'] = $not_allowed_error;
}
