Set validation on field when display in form

Sarbast

Hello,

I have two fields shows in the form according to a condition. I want to set validation "notEmpty" on these fields when show and off when hide.

Use this event: https://editor.datatables.net/reference/event/initSubmit

And there is also an example on that page:

Hello rf1234,

I have looked at these examples, but it doesn't work for my scenario. I just want to disable "required" attribute with hidden fields.

Hi,

You'll need to use a server-side event (e.g. preCreate and preEdit in this case) to add a notEmpty validator to the correct field. You'll also need to know what the correct field is to be able to do that - I'm not sure what logic you are using to determine that though?

@rf1234 - Nice reference to Section 31

Hi Allan,

Could you please give me an example.

Thanks

->on('preCreate', function ($editor) {
  if (/* some condition */) {
    $editor->field('field1')->validator( Validate::notEmpty() );
  }
  else {
    $editor->field('field2')->validator( Validate::notEmpty() );
  }
})

Obviously it needs the logic for the condition filled in, I don't know what you need for that, the field names and any other customisation you need, but that's the basic structure. Use similar for preEdit.
