Attachment Pages Redirect Plugin
Redirect attachment pages or return a 404 error for them based on the parent post status.
There are three possible scenarios where this plugin does something. In all cases, the attachment page must exists, the plugin will not run for deleted attachments:
A) A visitor lands on an attachment page and the parent post is available (not in trash or deleted). A 301 redirect will be issued to redirect the visitor to the parent post.
B) A visitor lands on an attachment page and the parent post was already deleted from trash. A 302 redirect is issued to home page (this can be changed to 301 if you want, see FAQ for more details).
C) A visitor lands on an attachment page and the parent post is in trash, therefore not available for the visitor. It returns a 404 error code to prevent endless redirection loop in old WP releases and redirecting to trashed/not available posts.
There is no options page, simply activate it and will do the job.
If you’re happy with the plugin please don’t forget to give it a good rating, it will motivate me to keep sharing and improving this plugin (and others).
Requirements
- WordPress 4.8 or higher.
Installation
- Extract the zip file and just drop the contents in the
wp-content/plugins/directory of your WordPress installation (or install it directly from your dashboard) and then activate the Plugin from Plugins page.
FAQ
No. This plugin needs an existing attachment to work, if you deleted the attachment WordPress will return a 404 for its attachment page and this plugin doesn’t support that scenario.
Since version 1.1 you can do this by adding constants to your wp-config.php file. The example below will switch the redirection codes used by default.
define( 'ATTACHMENT_REDIRECT_CODE', '302' ); define( 'ORPHAN_ATTACHMENT_REDIRECT_CODE', '301' ); Use this at your own risk, only if you know what you’re doing!! No support will be offered for this.
