    Block numbers in usernames at registration


    This tutorial will allow you to prevent usernames that contain numbers at registration, as in the example below.

    Setting up

    Go to Administration Panel > Modules > JavaScript Codes management and create a new script.

    Title : Your choice
    Placement : In all the pages
    Code:
    location.pathname=="/register" && location.search=="?agreed=true&step=2" && $(function(){
            
      var username_format = /^[^0-9]*$/;
      var format_notice = "Numbers are not allowed in usernames";
            
      var f = $('form[action=""][method="post"]');
      var p = $('#username_reg');
      var i = $('<span id="username_issue" />').html('<br/>'+format_notice).css({ "color":"red", "font-style":"italic", "display":"none"}).appendTo(p.parent());
            
      var u = function() {
        if (username_format.test(p.val())) i.hide();
        else {
          i.show();
          return false;
        }
      };
            
      p.on('change keyup', function(){ u() });
      $('input[type="reset"]', f).click(function(){ u() });
      $('input[type="submit"]', f).click(u);
      u();
            
    });


    Variants

    The script uses a regular expres​sion( /^[^0-9]*$/ ) to detect if the username contains a digit.


    Here are a few websites with tutorials on regular expressions :

    And some examples that could take the place of /^[^0-9]*$/ :

    Only allow usernames that contain digits :
    Code:
    /^[0-9]*$/

    Only allow usernames that contain 0 or 1 :
    Code:
    /^[01]*$/

    Only allow usernames that contain 3 words of 3-10 characters ( without a number ) :
    Code:
    /^(\b[^\d\s]{3,10}\b(\s+|$)){3}$/

    Don't allow usernames that contain special characters :
    Code:
    /^[^!@#$%^&*:;"',.?]*$/
