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.
