User System (Part 2)

Want to stop people registering on your site with names they shouldn't be using?
This tutorial will allow you to create a list of username which cannot be used during the signup process.

For this tutorial I will assume you already have folled the User System (Part 1) tutorial and this is working correctly.

Once you have that continue,

On Register.php find,

PHP Code Copy to clipboard

1
2
3

if(mysql_num_rows($cname) >= 1) { // If account with username already exists then do not continue
    echo "The username is already in use"; 
}

Before this add:

PHP Code Copy to clipboard

$blockedusernames = array("Bad Name 1","Bad Name 2","Bad Name 3");
if(in_array($username,$blockedusernames)) {
    $detected = "True";
}
if($detected == 'True') {
    echo "Bad username detected, Please use a different username.";
} else

This is a very simple yet effective way to stop people using usernames, you can add as many blocked names as you like to the array.

No this will detect a bad name and then block the rest of the code from running and registering and makes them go back to enter a new username.

We replace the Bad names with the names we want blocked right?

This scripts detects what ever phrase is in the array so if some one entered MOD-Dan and you have MOD in your array it will detect it.

MOD-Dan

Hey dude is there any way so that instead of blocking names you could have it so it blocks the perfix MOD- or MOD
