More Information

The wpforms_process_filter hook fires at the very end once the field validation and formatting the data.

Examples

Remember to change your form ID from 817 to the form ID that you’re targeting.

This example will look to see if there is a Ratings field on this particular form and if the user doesn’t complete this field, it will default the rating to 0.

function wpf_dev_process_filter( $fields, $entry, $form_data ) {
	
	$form_id = 817; // Change form ID
	
	// Bail early if form ID does not match
	if ( $form_data[ 'id' ] != $form_id ) {
		return $fields;
	}
	
	foreach ( $fields as $field ) {
		
		// If field type is rating and it is empty, assign a value of 0
		if ( $field[ 'type' ] == 'rating' && empty( $field[ 'value' ] ) ) {
			
			$fields[$field[ 'id' ]][ 'value' ] = 0;
			
		}
		
	}
	
	return $fields;
     
}
add_filter( 'wpforms_process_filter', 'wpf_dev_process_filter', 10, 3 );

Another example could be when the Show Values tutorial has been implemented to save the value instead of the label.

/**
 * Save choices `values` instead of `labels` for the fields with `Show values` option enabled.
 *
 * @link   https://wpforms.com/developers/wpforms_process_filter/
 *
 * @param  array  $fields    Sanitized entry field. values/properties.
 * @param  array  $entry     Original $_POST global.
 * @param  array  $form_data Form data and settings.

function wpf_dev_process_filter_choices_values( $fields, $entry, $form_data ) {

	if ( ! is_array( $fields ) ) {
		return $fields;
	}

	foreach ( $fields as $field_id => $field ) {
		if (
			isset( $field[ 'type' ] ) &&
			in_array( $field[ 'type' ], [ 'checkbox', 'radio', 'select' ], true ) &&
			! empty( $form_data[ 'fields' ][ $field_id ][ 'show_values' ] )
		) {
			$value_raw = ! empty( $field[ 'value_raw' ] ) ? $field[ 'value_raw' ] : '';
			$field[ 'value_raw' ] = $field[ 'value' ];
			$field[ 'value' ] = $value_raw;
