Hi,

I need a script that will check if a variable is 7 characters long or else spit out an error. This is just for the sign up password value on my site, since i dont want peaple getting their account stolen so easy.

Also, I tried this out and was wondering if you could tell me why it doesnt work.

if (!preg_match("/.*.*.*.*.*.*.*/", $_POST['passwd'])) {
            echo('Password needs to be 7 characters long.');
            include('register.html');
            exit();
      }


Thanks.

if strlen('passwd')<7) {
            echo('Password needs to be 7 characters long.');
            include('register.html');
            exit();
      }

I assume you want 7 or more characters. if you really want every password to be exactly 7 characters then change the < to ==

Well, you could do this with javascript.  In the <input> tag, just put maxlength=7, that will prevent users from entering a longer password.  So this is what your <input> tag would oook like:

<input type="password" maxlength="7" name="password">

Before i even try this code i can tell there is an error in there, and since ive never used this function before im not sure where the brackets go, please look this over. Thanks.

Ah nevermind, i fixed it myself......It should of been:

if (strlen($_POST['passwd'] < 7)) {
             echo('Password needs to be 7 characters long.');
             include('register.html');
             exit();
      }
