## 説明

This plugin lets you specify a maintenance mode message or HTML page for your site
and configure settings to allow specific users to bypass the maintenance mode functionality
in order to preview the site prior to public launch.

It also disables the WordPress REST API while maintenance mode is active, ensuring
that site data remains inaccessible during maintenance.

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.

Functionality to exclude pages from maintenance mode, so only the selected pages
will be visible.

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 four methods of notifying users that a site is undergoing maintenance:

 1. They can be presented with a message using WordPress’s wp_die() function which 
    is core function of WordPress, which makes this plugin feel and work as a part 
    of WordPress core.
 2. They can be presented with a message on a page created with the style of the current
    template.
 3. They can be presented with a custom HMTL page.
 4. They can be redirected to a static page or external URL.

## インストール

 1. Upload the `hkdev-maintenance-mode` folder to your plugins directory (usually `/
    wp-content/plugins/`).
 2. Activate the plugin through the `Plugins` menu in WordPress.
 3. Configure the settings through the `Maintenance Mode` Settings panel.

## FAQ

### How can I bypass the redirect programatically?

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

**`hkdev_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_hkdev_matches( $hkdev_matches ) {
        if ( stristr( $_SERVER['REQUEST_URI'], 'demo' ) ) 
            $hkdev_matches[] = "<!-- Demo -->";
        return $hkdev_matches;
    }
    add_filter( "hkdev_matches", "my_hkdev_matches" );`
    ```

_Props to @brianhenryie for this!_

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

By default, Maintenance Mode 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:

**`hkdev_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_hkdev_user_can( $capability ) {
        return "edit_posts";
    }
    add_filter( "hkdev_user_can", "my_hkdev_user_can" );
    ```

An excellent option for a maintenance page or a development shield. Provides a suitable
selection of comprehensive options and does not bombard the site owner / admin with
obnoxious upgrade requests nor animated distractions.

This plugin broke my whole site. I couldn’t even login to the admin section. Captcha
dissapeared. I had to reinstall it again. DO NOT INSTALL IT!!!!!

Straight to the point plugin, works great and the IP whitelist is a great feature.
Tried a lot of them, but this one hit the spot.

I use this to put a kind of “anyone with the link can access” on our family blog—
not the intended use, but it works well for it. My main wish list feature would 
be to have keys that work on a per-post (or per category or tag) basis, but understand
that’s beyond the scope of the intended purpose.
