Usage

add_filter('frm_graph_value', 'my_custom_graph_value', 10, 2);

Parameters

  • $value (mixed)
  • $field (object)

Examples

Use typed signature

This is from the signature add-on to tell the graphs to use the typed signature instead of the written one.

add_filter('frm_graph_value', 'my_custom_graph_value', 10, 2);
function my_custom_graph_value( $value, $field ) {
    if ( is_object( $field ) && $field->type == 'signature' ) {

        if ( is_array( $value ) ) {
            if ( ( ! isset( $value['output'] ) || empty( $value['output'] ) ) ) {
                $value = isset( $value['typed'] ) ? $value['typed'] : reset( $value );
            } else {
                $value = '';
            }
        }
    }

    return $value;
}

Basic Example

Change a graph value.

add_filter('frm_graph_value', 'my_custom_graph_value', 10, 2);
function my_custom_graph_value( $value, $field ) {
    if ( $field->id == 123 ) {
        $value = 'new value';
    }

    return $value;
}
