  Examples

  Set fields to read-only when editing

  Use this code to make certain fields read-only when editing the entry on the front-end. Limitation: This hook does not work when a Lookup field is watching another Lookup field.

  add_filter('frm_setup_edit_fields_vars', 'frm_set_read_only', 20, 3);
  function frm_set_read_only($values, $field, $entry_id){
  	// If on the back-end, keep fields editable
  	if ( FrmAppHelper::is_admin() ) {
  	  return $values;
    	}
  
  	// If on front-end, make specific fields read-only
  	if ( in_array( $field->id, array( 1558,554,555,556 ) ) ) { 
  	   $values['read_only'] = 1;
  	}	
  	return $values;
  }

  add_filter('frm_setup_edit_fields_vars', 'frm_set_edit_val', 20, 3);
  function frm_set_edit_val( $values, $field, $entry_id ) {
  if ( $field->id == 171 ) { //Replace 171 with your field ID
  	// If on the back-end, don't adjust field value
  	if ( FrmAppHelper::is_admin() ) {
  	  return $values;
    	}
  
  	// If on front-end set a specific field value
          $values['value'] = 'new value';
  }
  return $values;
  }
  

  Show Removed Option

  If an option is removed from a radio, dropdown, or checkbox field, previous entries are not affected. However, if those older entries are edited, the selected value will be missing and cannot be selected. This snippet will show the option in the field when editing.

  add_filter('frm_setup_edit_fields_vars', 'show_removed_options', 25, 2);
  function show_removed_options( $values, $field ) {
  	if ( FrmAppHelper::is_admin_page('formidable') || empty( $values['value'] ) ) {
  		return $values;
  	}
  		
  	if ( in_array( $field->type, array( 'select', 'radio', 'checkbox' ) ) ) {
  		if ( ! in_array( $values['value'], $values['options'] ) ) {
  			$values['options'][ $values['value'] ] = $values['value'];
  		}
  	}
  	return $values;
  }
  

  Copy field value

  Use the code below to set a value, typically in a hidden field, to the current value of another field. This is helpful if you want to compare the two fields after the entry is updated to see if the original field value was updated.

  add_filter('frm_setup_edit_fields_vars', 'frm_copy_field_value_before_edit', 20, 3);
  function frm_copy_field_value_before_edit( $values, $field, $entry_id ) {
          if ( $field->id == 171 ) { //Replace 171 with the field ID of the field that you want to store the original entry in
  		// If on the back-end, don't adjust field value
  		if ( FrmAppHelper::is_admin() ) {
  			return $values;
  		}
  
  		// If on front-end set a specific field value
  		$args = array(
                          'field_id' => $field->id, //change $field->id to the ID of the field that has the original entry
  			'entry' => $entry_id,
  		);
  
  		$values['value'] = FrmProEntriesController::get_field_value_shortcode( $args );
  	}
  	
  	return $values;
  }
  

  Copy multiple field values

  Use the code below to save the original values of multiple fields in Hidden (or other types of) fields. This is helpful if you want to see if there have been changes to multiple fields when the entry is edited.

  For the field pairs, put the id of the Hidden field to the left of the arrow and the id of the original field (the one you want to copy) on the right. You can add as many additional pairs as you'd like or remove pairs, if you have fewer than three.

  add_filter('frm_setup_edit_fields_vars', 'frm_copy_multiple_field_values_before_edit', 20, 3);
  function frm_copy_multiple_field_values_before_edit( $values, $field, $entry_id ) {
  	if ( FrmAppHelper::is_admin() ) {  //don't copy the field value if the entry is edited in the admin area
  		return $values;
  	}
  
  	$field_pairs = array( //for each pair of fields, put the id of the copy on the left and the original field on the right
  		7327 => 7326,
  		7329 => 7328,
  		7331 => 7330,
  	);
  
  	if ( ! empty( $field_pairs[$field->id])){
  		$args = array(
  			'field_id' => $field_pairs[$field->id],
  			'entry' => $entry_id,
  		);
  
  		$values['value'] = FrmProEntriesController::get_field_value_shortcode( $args );
  	}
  
  	return $values;
  }
