Maintenance Redirect

Beschreibung

This plugin is intended primarily for designers / developers that need to allow clients to preview sites before being available to the general public or to temporarily hide your WordPress site while undergoing major updates.

Any logged in user with WordPress administrator privileges will be allowed to view the site regardless of the settings in the plugin. The exact privilege can be set using a filter hook – see FAQs.

The behaviour of this can be enabled or disabled at any time without losing any of settings configured in its settings pane. However, deactivating the plugin is recommended versus having it activated while disabled.

When redirect is enabled it can send 2 different header types. “200 OK” is best used for when the site is under development and “503 Service Temporarily Unavailable” is best for when the site is temporarily taken offline for small amendments. If used for a long period of time, 503 can damage your Google ranking.

A list of IP addresses can be set up to completely bypass maintenance mode. This option is useful when needing to allow a client’s entire office to access the site while in maintenance mode without needing to maintain individual access keys.

Access keys work by creating a key on the user’s computer that will be checked against when maintenance mode is active. When a new key is created, a link to create the access key cookie will be emailed to the email address provided. Access can then be revoked either by disabling or deleting the key.

This plugin allows three methods of notifying users that a site is undergoing maintenance:

  1. They can be presented with a message on a page created by information entered into the plugin settings pane.

  2. They can be presented with a custom HMTL page.

  3. They can be redirected to a static page. This static page will need to be uploaded to the server via FTP or some other method. This plugin DOES NOT include any way to upload the static page file.

FAQ

How can I bypass the redirect programatically?

There is a filter which allow you to programatically bypass the redirection block:

wpjf3_matches

This allows you to run pretty much any test you like, although be aware that the whole redirection thing runs before the $post global is set up, so WordPress conditionals such as is_post() and is_tax() are not available.

This example looks in the $_SERVER global to see if any part of the URL contains „demo“

function my_wpjf3_matches( $wpjf3_matches ) {
    if ( stristr( $_SERVER['REQUEST_URI'], 'demo' ) ) 
        $wpjf3_matches[] = "<!-- Demo -->";
    return $wpjf3_matches;
}
add_filter( "wpjf3_matches", "my_wpjf3_matches" );`

Props to @brianhenryie for this!

How can I let my logged-in user see the front end?

By default, Maintenance Redirect uses the manage_options cap, but that is normally only applied to administrators. As it stands, a user with a lesser permissions level, such as editor, is able to view the admin side of the site, but not the front end. You can change this using this filter:

wpjf3_user_can

This filter is used to pass a different WordPress capability to check if the logged-in user has permission to view the site and thus bypass the redirection, such as edit_posts. Note that this is run before $post is set up, so WordPress conditionals such as is_post() and is_tax() are not available. However, it’s not really meant for programatically determining whether a user should have access, but rather just changing the default capability to be tested, so you don’t really need to do anything other than the example below.

function my_wpjf3_user_can( $capability ) {
    return "edit_posts";
}
add_filter( "wpjf3_user_can", "my_wpjf3_user_can" );

I appreciate the option to allow any # of specified IP addresses to bypass the redirect. Helpful during development.

Even though this hasn't been updated, it's an excellent plugin and I use it on all my sites. Love the fact that you can share an access key with a client (best to mail it to yourself and then send them the link so it doesn't get caught in their junk mail). Two thumbs up from me!!
