I have a page that lists all live posts on a single page, with an edit link next to each one of them. The edit link to a post looks like this:

site.com/edit/?pid=3329&_wpnonce=9b37f6bacd

where 3329 is the {post_id}. Clicking the edit link takes the user to a form with shortcode:

[gravityforms id="1" update="xx"]

Is there a way i can update "xx" with 3329? Via PHP, I tried this:

$post_ID = get_query_var( 'pid' );

echo do_shortcode( '[gravityform id="2" update="' . $post_ID . '"]' );

but it doesn't seem to work. Any idea where I'm failing?

To use get_query_var, you must first register the query variable with the query_vars filter.

add_filter( 'query_vars', 'wpse251014_query_vars' );
function wpse251014_query_vars( $query_vars ) {
    $query_vars[] = 'pid';
    return $query_vars;
}

Reference: get_query_var

  • Hmm, that doesn't seem to work. Is it my shortcode that is causing the problem? <?php add_filter( 'query_vars', 'wpse251014_query_vars' ); function wpse251014_query_vars( $query_vars ) { $query_vars[] = 'pid'; return $query_vars; } $post_ID = get_query_var( 'pid' ); echo do_shortcode( '[gravityform id="11" update="' . $post_ID . '" title="false" description="false"]' ); ?>
