[Resolved] Required field settings for post parent and featured image

This thread is resolved. Here is a description of the problem and solution.

Problem: I would like to make the post parent field and featured image field required in my CRED form.

Solution: The parent post CRED field shortcode will accept a required='true' attribute like this:

[cred_field field='_wpcf_belongs_slug_id' value='' select_text='--- not set ---' class='form-control' output='bootstrap' required='true']

The featured image shortcode will not accept a required='true' attribute, so the only way to require a featured image is to use custom code. The CRED API cred_form_validate can be used to make the featured image required. Add this code to your child theme's functions.php file:

add_filter( 'cred_form_validate', 'require_featured_image_validation', 10, 2 );
function require_featured_image_validation( $data, $form_data ) {
  $forms = array( 1234, 5678 );
  if( in_array( $form_data['id'], $forms ) ){
    list($fields,$errors)=$data;
    if (empty($fields['_featured_image']['value'])) {
      $errors['_featured_image'] = __( 'Featured image is required', 'your-language-domain');
    }
    $data =array($fields,$errors);
  }
  return $data;
}

Replace 1234, 5678 with a comma-separated list of any CRED form IDs where you want to make the featured image required.

How to set WordPress fields (ie 'Featured Image') and Relationship fields (ie parent post type Slection field of 'Belongs to Country' - 'Country' drop down field is pulled by parent post type) as obligatory fields (in CRED)?

The parent post CRED field shortcode will accept a required='true' attribute like this:

[cred_field field='_wpcf_belongs_slug_id' value='' select_text='--- not set ---' class='form-control' output='bootstrap' required='true']

The featured image shortcode will not accept a required='true' attribute, so the only way to require a featured image is to use custom code. The CRED API cred_form_validate can be used to make the featured image required. Add this code to your child theme's functions.php file:

add_filter( 'cred_form_validate', 'require_featured_image_validation', 10, 2 );
function require_featured_image_validation( $data, $form_data ) {
  $forms = array( 1234, 5678 );
  if( in_array( $form_data['id'], $forms ) ){
    list($fields,$errors)=$data;
    if (empty($fields['_featured_image']['value'])) {
      $errors['_featured_image'] = __( 'Featured image is required', 'your-language-domain');
    }
    $data =array($fields,$errors);
  }
  return $data;
}

Replace 1234, 5678 with a comma-separated list of any CRED form IDs where you want to make the featured image required.
