Strip X number of characters filter

David,

Would it be a big job to write a filter to strip x number of characters from the front of a field? If it is don't worry about it.

Thanks
Dave

Hi Dave,

Have a go with this;

<?php
  /*************************************************/
  /* stripX                                        */
  /*************************************************/
  $filter_names["stripX"] = "Strip X";
  function filter_stripXConfigure($filter_data)
  {
    print "Number of characters to strip:<br />";
    print "<input type='text' name='num' value='".widget_safe($filter_data["num"])."' />";
    widget_errorGet("num");
  }
  function filter_stripXValidate($filter_data)
  {
    if (!intval($filter_data["num"]))
    {
      widget_errorSet("num","number required");
    }
  }
  function filter_stripXExec($filter_data,$text)
  {
    return substr($text,intval($filter_data["num"]));
  }
?>

Cheers,
David.
