Safe Redirect Manager

A WordPress plugin to safely and easily manage your website's HTTP redirects.

Purpose

Easily and safely manage your site's redirects the WordPress way. There are many redirect plugins available. Most of them store redirects in the options table or in custom tables. Most of them provide tons of unnecessary options. Some of them have serious performance implications (404 error logging). Safe Redirect Manager stores redirects as Custom Post Types. This makes your data portable and your website scalable. Safe Redirect Manager is built to handle enterprise level traffic and is used on major publishing websites. The plugin comes with only what you need following the WordPress mantra decisions not options. Actions in filters make the plugin very extensible.

Installation

Install the plugin in WordPress, you can download a zip via Github and upload it using the WP plugin uploader.

Configuration

There are no overarching settings for this plugin. To manager redirects navigate to the administration panel. Within the main menu, click "Tools" > "Safe Redirect Manager".

Each redirect contains a few fields that you can utilize:

"Redirect From"

This should be a path relative to the root of your WordPress installation. When someone visits your site with a path that matches this one, a redirect will occur. If your site is located at http://example.com/wp/ and you wanted to redirect http://example.com/wp/about to http://example.com, your "Redirect From" would be /about.

Clicking the "Enable Regex" checkbox allows you to use regular expressions in your path. There are many great tutorials on regular expressions.

You can also use wildcards in your "Redirect From" paths. By adding an * at the end of a URL, your redirect will match any request that starts with your "Redirect From". Wildcards support replacements. This means if you have a wildcard in your from path that matches a string, you can have that string replace a wildcard character in your "Redirect To" path. For example, if your "Redirect From" is /test/*, your "Redirect To" is ````http://google.com/*```, and the requested path is /test/string, the user would be redirect to ```http://google.com/string```.

"Redirect To"

This should be a path i.e. /test or a URL i.e. http://example.com/wp/test. If a requested path matches "Redirect From", they will be redirected here. "Redirect To" supports wildcard and regular expression replacements.

"HTTP Status Code"

HTTP status codes are numbers that contain information about a request i.e. whether it was successful, unauthorized, not found, etc. You should almost always use either 302, temporarily moved, or 301, permanently moved.

Development

Setup

Follow the configuration instructions above to setup the plugin. I recommend developing the plugin locally in an environment such as Varying Vagrant Vagrants.

Testing

Within the terminal change directories to the plugin folder. Initialize your unit testing environment by running the following command:

For VVV users:

bash bin/install-wp-tests.sh wordpress_test root root localhost latest

For VIP Quickstart users:

bash bin/install-wp-tests.sh wordpress_test root '' localhost latest

where:

  • wordpress_test is the name of the test database (all data will be deleted!)
  • root is the MySQL user name
  • root is the MySQL user password (if you're running VVV). Blank if you're running VIP Quickstart.
  • localhost is the MySQL server host
  • latest is the WordPress version; could also be 3.7, 3.6.2 etc.

Run the plugin tests:

phpunit
