[SOLVED] Easy question

[boney alex]

Ive got this function which checks the username contains only letters and numbers and is between 6-12 characters long. How do I change this function to only allow letters and spaces and be of any length?

<?
function usernamecheck($username) 
{
if (eregi ("^[[:alnum:]]{6,12}$", $username)) 
{
return true;
} 
else 
{
return false;
}
}
?>

 

Cheers

Try something like:

<?php

function usernamecheck($username){
   if(eregi("^[a-zA-Z ]*$", $username)){
      return true;
   }

   else{
      return false;
   }
}

?>

You should probably "trim" the value to remove leading and trailing spaces though. Also, do you want to allow consecutive spaces? If not, you can create a regex for that.
