Attachment posts showing an array (issue | url rewriting)

Replies: 0

Hello,

I have added this function in order to rewrite the permalink structure of my attachments :

add_filter( 'attachment_link', 'wpd_attachment_link', 20, 2 );
function wpd_attachment_link( $link, $attachment_id ){

    $attachment = get_post( $attachment_id );

    // Only for attachments actually attached to a parent post
    if( ! empty( $attachment->post_parent ) ) {

        $parent_link = get_permalink( $attachment->post_parent );
        // make the link compatible with permalink settings with or without "/" at the end
        $parent_link = rtrim( $parent_link, "/" );
        $link =  $parent_link . '/gallerie/' . $attachment_id;

    }

    echo $link;

}

add_action( 'init', function() {

    // Tell WordPress how to handle the new structure
    add_rewrite_rule( '(.+)/gallerie/([0-9]{1,})/?$', 'index.php?attachment_id=$matches[2]', 'top' );

} );

The problem I encounter is that the displayed content is an array, not the image. Since the permalink is working, I wonder why wordpress is unable to display the image.

Any idea?

Regards.
