Formidable Forms PRO - "Previous" Button Label Not Translatable

Overview of the issue

When using WPML with Formidable Forms PRO and the Formidable Multilingual add-on, the « Previous » button label from the Page Break field is not available for translation. This label does not appear in WPML’s String Translation or in the Formidable « Translate Form » settings.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

Formidable Forms PRO

• Open …/wp-content/plugins/formidable-pro/classes/models/fields/FrmProFieldBreak.php
• Look for line 121
• Replace:

  	public function translatable_strings() {
  		return array( 'name' );
  	}				
  

• With:

  	public function translatable_strings() {
  		return array( 'name', 'prev_label' );
  	}
  

Formidable Multilingual

• Open …/wp-content/plugins/formidable-wpml/models/FrmWpmlString.php
• Look for line 95
• Replace:

  			case 'break':
  				$keys = array( 'name' );
  				break;			
  

• With:

  			case 'break':
  				$keys = array( 'name', 'prev_label' );
  				break;
  

• In the same file, look for line 502
• Replace:

  				break;
  

• With:

  				break;
  			case 'break':
  					if ( isset( $field->field_options['prev_label'] ) && $field->field_options['prev_label'] != '' ) {
  						$string_data[ 'field-' . $field->id . '-prev_label' ] = $field->field_options['prev_label'];
  					}
  				break;
  

• After completing these steps, the « Previous » button label should become translatable in Formidable > Forms > Form Settings > Translate Form.
