Troubleshooting and Developer Filters

Customizing Shortcode Output #

For advanced customization of shortcode output, the plugin provides the alg_wc_pdf_invoicing_return_prop filter. This allows developers to intercept and modify the value returned by any shortcode.

Filter Example #

The following example demonstrates how to use a custom attribute (my_custom_filter="1") on a shortcode to trigger a custom date format based on the current language:

add_filter(
    'alg_wc_pdf_invoicing_return_prop',
    function ( $value, $atts, $shortcodes_obj ) {

        // Run only when the custom attribute is present
        if ( empty( $atts['my_custom_filter'] ) ) {
            return $value;
        }

        $language  = strtoupper(
            $shortcodes_obj->get_current_language_for_translate()
        );
        $timestamp = strtotime( $value );

        switch ( $language ) {
            case 'DE':
                // Custom German date format
                return date( 'F j, Y, g:i a', $timestamp );

            default:
                // Default format
                return date( 'Y-m-d H:i:s', $timestamp );
        }
    },
    10,
    3
);
