Making field option required depending on other field [#1696608]

Hi,

I have a field collection field as "main_field_collection_field".
Then have 2 fields in that collection as "field_1" and "field_2".
None of these 3 fields have the Required option checked.

Can I use this module to make the field_2 to be required whenever there is some/any data in field_1 on form submission?

Thanks...

Currently, such issue could be solved by php code validator.

I would be very very happy if you can provide a sample for me. My own php knowledge is almost zero.

Thank you soooo much :)

add php code validator to field_2
sample code :

if(!empty($this->entity->field_1['und'][0]['value'])){
  if(empty($this->value)){
$this->set_error();
}
}

I tried this however no luck, the field saves and no error with the textfield is empty.

My setup is a field collection where a user can add a Youtube video or upload a video. The title field needs to be required when either video field is added.

At the moment I have the following setup:

field_video_title
field_video_yt (the php rule above I have added but no luck)
field_video_upload

Is there something I am missing?
