functions.php

if ( isset( $_GET['user_id'] ) && $_GET['ld_certificate'] ) {
	include_once LEARNDASH_LMS_PLUGIN_DIR . 'includes/ld-convert-post-pdf.php';
	learndash_certificate_post_shortcode(
		$cert_args = array(
			'user_id' => esc_attr(
				$_GET['user_id']
			),
			'cert_id' => esc_attr(
				$_GET['ld_certificate']
			),
			'post_id' => esc_attr(
				$_GET['ld_certificate']
			),
		),
	);
	die;
}

function learndash_get_certificate_link_by_user_id( $atts ) {
    // Extract shortcode attributes
    $atts = shortcode_atts( array(
        'user_id'        => get_current_user_id(),
		'ld_certificate' => '',
    ), $atts );

    // Retrieve attribute values
    $user_id = $atts['user_id'];
	$cert_id = $atts['ld_certificate'];
	
	$cert_link       = get_permalink( $cert_id );
	$certificate     = get_post( $cert_id );
	$cert_query_args = array(
		'user_id'        => ( $user_id ? $user_id : get_current_user_id() ),
		'ld_certificate' => $cert_id,
	);

	$url = add_query_arg( $cert_query_args, $cert_link );

	return '<a rel="noopener" target="_blank" href="' . esc_url_raw( $url ) . '">' . esc_html( $certificate->post_title ) . '</a>';
}
add_shortcode( 'ld_cert_by_user', 'learndash_get_certificate_link_by_user_id' );

1. Place the above snippet in your theme's functions.php file
2. Add this shortcode to any of your pages or post to show the certificate link.

[ld_cert_by_user ld_certificate="{your_ld_certificate_post_id}"]

great job you've done with this code.

I have an issue I've been battling with and I need your input, how do I get and display the user certificate ID and as a shortcode.

Thanks for support in adcance
