#24612 reopened defect (bug)

Permalink conflict: image attachment page and post when permalink setting is /%postname%/

Reported by: augustas Owned by:
Milestone: Awaiting Review Priority: normal
Severity: normal Version: 3.3
Component: Permalinks Keywords: has-patch needs-unit-tests
Focuses: Cc:


Here is scenario when there is a permalink conflict between the "attachment page" URL and post when image filename and post name are equal:
Permalinks are set to /%postname%/

Using Media -> Library -> upload new image called about-me.jpg
System saves into "wp_posts" database table: post_name = "about-me"

I publish a new POST with the title "About Me". For this post database stores the post_name = "about-me"

If I go to URL: www.example.com/about-me/ - I am redirected to about-me.jpg Image Attachment Page.

If POST is created first and the image uploaded second - URL will open the POST.

This issue is similar to #13459

I ran into this yesterday. I definitely think that posts should take precedence over attachments in this case. Especially since the UI to change media slugs is hidden in screen options by default.

  • Keywords has-patch needs-unit-tests added
  • Version changed from 3.5.1 to 3.3

Introduced in [18541], specifically with the changes in WP_Rewrite::page_rewrite_rules().

24612.patch fixes it for me.

24612.patch works for me. It's very specific to "post" though. Do we want to assume that handling slug conflicts for custom post types should be done in the plugin that creates the post type?

A workaround:

function wp24612_resolve_post_vs_attachment_permalink_conflict( $query ) {
	if ( is_admin() || ! $query->is_main_query() ) {

	if ( ! preg_match( "/^[^%]*%(?:postname)%/", get_option( 'permalink_structure' ) ) ) {

	if ( empty( $query->queried_object ) || '' === $query->get( 'pagename' ) ) {

	if ( 'attachment' === $query->queried_object->post_type ) {
		// See if we also have a post with the same slug
		$post = get_page_by_path( $query->get( 'pagename' ), OBJECT, 'post' );
		if ( $post ) {
			$query->queried_object    = $post;
			$query->queried_object_id = (int) $post->ID;
			$query->is_page           = false;
			$query->is_single         = true;
add_action( 'parse_query', 'wp24612_resolve_post_vs_attachment_permalink_conflict' );
