Call current post parameters inside a plugin

Question

I edited the plugin WP User Frontend (for editing posts from frontend) to have two different edit pages for two different post types. Here's the original function which handles the edit_link.

function wpuf_edit_post_link( $url, $post_id ) {
if ( is_admin() ) {
    return $url;
}

$override = wpuf_get_option( 'override_editlink', 'yes' );
if ( $override == 'yes' ) {
    $url = '';
    if ( wpuf_get_option( 'enable_post_edit' ) == 'yes' ) {
        $edit_page = (int) wpuf_get_option( 'edit_page_id' );
        $url = get_permalink( $edit_page );

        $url = wp_nonce_url( $url . '?pid=' . $post_id, 'wpuf_edit' );
    }
}

return $url;
}

add_filter( 'get_edit_post_link', 'wpuf_edit_post_link', 10, 2 );

How can I call the current post parameters inside the function? I used get_post but it doesn't work (I guess because it's not inside the loop...). Here's the piece of function I edited. 201 and 203 are correct edit pages IDs: inside the pages there is some shortcode which turns them into an edit page.

$override = wpuf_get_option( 'override_editlink', 'yes' );
if ( $override == 'yes' ) {
    $url = '';
    if ( wpuf_get_option( 'enable_post_edit' ) == 'yes' ) {

    $post = get_post($post_id);

    if ($post->post_type == 'type1') {
        $url = get_permalink( 201 );
        $url = wp_nonce_url( $url . '?pid=' . $post_id, 'wpuf_edit' );
    }

    if ($post->post_type == 'type2') {
        $url = get_permalink( 203 );
        $url = wp_nonce_url( $url . '?pid=' . $post_id, 'wpuf_edit' );
    }
    }
}

What's wrong with this code?

Answer 1

Instead of using $post = get_post($post_id);, you can call global $post; which will load the value of the current post assuming that you have not triggered any other loops.
