I have used the below

<input type="text" value="" class="input-text required-entry validate-number validate-length minimum-length-4 maximum-length-8" title="Purchase Order" name="custom1" id="custom1">

For validating length the maximum-length-8 works. But minimum-length-4 not working. Somebody please let me know if you have any solution

  • this seems correct, can you share a link OR full form's HTML that contains this element ? Jun 16, 2016 at 12:16
  • Did you able to find any solution for this issue? if so can you please update here. Oct 22, 2018 at 15:14
