The Ad details pages do not use shortcodes, but you can register a shortcode which will disaply an Ad details page by adding the code below in your theme functions.php file
add_shortcode( "advert_single", function( $args ) {
ob_start();
if( isset( $args["post_id"] ) ) {
$post_id = $args["post_id"];
} else {
$post_id = get_the_ID();
}
$post_content = get_post( $post_id )->post_content;
$post_content = wp_kses($post_content, wp_kses_allowed_html( 'post' ) );
$post_content = apply_filters( "adverts_the_content", $post_content );
include apply_filters( "adverts_template_load", ADVERTS_PATH . 'templates/single.php' );
$content = ob_get_clean();
return $content;
});
The to display the Advert details somewhere you can use the shortcode as [advert_single post_id="100"]
where 100 is an actual ID of an Ad you would like to display.
