Cakephp Maintenance Mode

CakePHP Maintenance Mode is to put your website in maintenance mode while you do your upgrade. Most ppl would add a static file on the server and route all request to it during maintenance. The file is shown to everybody including you unless a rewrite rule or expressions is added to exclude yourself which would complicate the matter.

This filter file would tell CakePHP to put all requests to maintenance mode i.e show a msg but would allow requests from your IPs to be processed normally.

##Requirement CakePHP 2.*

Installation

[Using Composer]

View on Packagist, and copy the JSON snippet for the latest version into your project's composer.json. Eg, v. 1.2.0 would look like this:

{
	"require": {
		"awebdeveloper/cakephp-maintenance-mode": "1.2.0"
	}
}

Because this plugin has the type cakephp-plugin set in it's own composer.json, composer knows to install it inside your /Plugin directory, rather than in the usual vendor directory. It is recommended that you add /Plugin/MaintenanceMode to your .gitignore file. (Why? Read this.)

[Manual]

• Download this: http://github.com/awebdeveloper/cakephp-maintenance-mode/zipball/master
• Unzip that download.
• Copy the resulting folder to app/Plugin
• Rename the folder you just copied to MaintenanceMode

In your app directory type:

git submodule add -b master git://github.com/awebdeveloper/cakephp-maintenance-mode.git Plugin/MaintenanceMode
