vc_font_container_output_data

Filters the rendered output data array for the font container parameter before it is assembled into the final HTML output. Each key in the data array corresponds to a font container field (e.g., tag, font_family, font_size, color, text_align, line_height) and contains its rendered HTML template.

Parameters

Parameter	Type	Description
$data	array	An associative array of rendered HTML strings, keyed by field name (e.g., tag, font_family, font_size, color, text_align, line_height).
$fields	array	The font container fields configuration array.
$values	array	The current values for each field.
$settings	array	The parameter settings array.

Usage

add_filter( 'vc_font_container_output_data', 'wpb_modify_font_container_output', 10, 4 );

function wpb_modify_font_container_output( $data, $fields, $values, $settings ) {
    // Add a custom field output after the existing fields
    if ( isset( $fields['font_size'] ) ) {
        $data['font_size'] .= '<p class="description">Enter size in px, em, or rem.</p>';
    }
    return $data;
