## Описание

4zero4 makes your 404 pages useful. When a visitor reaches a URL that no longer

exists, the plugin builds a search query from the requested address and redirects
the visitor to your site’s search results, so they land on relevant content instead
of an empty error page.

For example, a request for `/my-old-product-name/` that no longer resolves is
 turned
into a search for «my old product name».

Key points:

 * **Zero configuration.** Activate it and it works.
 * **Temporary redirect (302).** The original URL may become valid again, so the
   
   redirect is never cached as permanently moved.
 * **Front-end only.** It never interferes with the admin area, feeds or the REST
   
   API, and only acts on normal GET page views.
 * **No external services.** The plugin does not send any data anywhere and does
   
   not use tracking or analytics.

#### Developer hooks

The behaviour can be customised with filters:

 * `p4zero4_search_terms` — change (or clear, to skip) the terms extracted from 
   the URL.
 * `p4zero4_redirect_url` — change (or clear, to cancel) the destination URL.
 * `p4zero4_redirect_status` — change the HTTP status code (default `302`).

## Установка

 1. Upload the `4zero4` folder to `/wp-content/plugins/`, or install the plugin
     from
    the Plugins screen in WordPress.
 2. Activate the plugin through the «Plugins» menu in WordPress.
 3. That’s it — there are no settings. Any 404 will now redirect to a matching
     site
    search.

## Часто задаваемые вопросы

### Does the plugin have a settings page?

No. It works out of the box with no configuration.

### Why am I redirected with a 302 and not a 301?

A 404 is, by definition, temporary: the page might be restored later. A permanent

301 redirect would be cached by browsers and search engines and would be hard to
undo. You can change the status code with the `p4zero4_redirect_status` filter.

### Can I customise the search terms or the destination?

Yes. Use the `p4zero4_search_terms`, `p4zero4_redirect_url` and
 p4zero4_redirect_status
filters described in the Description.

### Does the plugin send any data to external services?

No. It performs a local redirect on your own site and contacts no third party.

## Журнал изменений

#### 1.2

 * Security: the requested URL is now read, unslashed and sanitised safely instead
   
   of using a raw server variable.
 * Redirects now use `wp_safe_redirect()` with a temporary 302 status instead of
   a
    raw permanent 301 header.
 * Switched to the `template_redirect` hook and added guards for admin, feeds, REST
   
   and non-GET requests.
 * Added a guard against direct file access (ABSPATH check).
 * Added the `p4zero4_search_terms`, `p4zero4_redirect_url` and
    p4zero4_redirect_status
   filters.
 * Completed the plugin header (License, Text Domain, Requires at least, Requires
   PHP).
 * Rewrote the readme in English with full sections; fixed the Stable tag to match
   
   the plugin version.
