      Hi!

      Please, help me. How can I check that the contents of the text box is a number?
      Something like this:
      ‘validate’ => array(
      array(
      ‘type’ => ‘numeric’
      )
      )

      You can register your own validation function.

      Use the callback method here >

      Untested, but this should work:

      function my_validate_numeric($file, $field, $arguments)
{
  return is_numeric($file) ? true : 'is not numeric.';
}
