You can load plugin in this way:

If you are already using Plugin::loadAll();, then this is not necessary.

Usage

You can run this plugin from all your controller (except AppController) inside beforeFilter action, because every time user try to load a page there is a check of permission to understand if that user can access to the next page. You need to include the plugin component inside your controller like this:

If you have already declare your variable $components you can do something like this:

Inside your action beforeFilter you can set rules for group of user that you want. For example:

And to run the check function you only need this line of code:

Now everytime that you load a page inside this controller the plugin check for the user logged if he can access to next page.

Settings

There are some parameters that you can use into this plugin:

• user_type
• redirect
• message
• action
• controller
• groups
• views

user_type

Is the group name of the user (or the username if you check by username not by user group). You need to pass this information to the plugin to compare users and permission that you give. Usually inside table users, every user have a group field to understand if is an admin, a normal user etc. You can pass the value user_type for example in this way:

I advise you tu use field group inside your table and insert it inside session or use a function to retrieve this information. if you don't want to use group field, isn't important. The important is , for example, if you would like to use field "username", inside the array groups you need to insert the username list not the group list for example:

Redirect

This parameter allow you to set a redirect page if the user doesn't have permission to access at the next page. You can set this parameter like this:

or

If you don't want to use this parameter you can leave it blank or you can omitted it like this:

Message

This parameter allow you to set a specific message inside flash message session. You can insert the string that you want, you can leave it blank or you can to omitted id if you don't want to set a specific message.

Action

This parameter is mandatory and it's standard. You have always to pass this parameter in this way

You can't omitted it or you can't modified it, is a standard parameter.

Controller

This parameter is mandatory and it's standard. You have always to pass this parameter in this way:

You can't omitted it or you can't modified it, is a standard parameter.

Groups

This is an array of array. Inside this array you can create list of user group to specify which page can be view by that user group, or user. You can insert inside this array, gropu name or username (in base of user_type), inside it you can specify the action of this controller that this group can access to it for example:

In this case you have told to the plugin:

• guest: not logged is a standard parameter, automatically the plugin understand if the user is a guest or not. You have specify that not logged user can access only to register and login view.
• admin: you have specify that user in group admin can access to all views of this controller. The character * means that this user is able to access to all views of this controller
• admin-team: you have specify that user in group admin-team can access to these views: register, add, logout, index and edit.
• user: you have specify that user in group user can access to these views: register, logout and index.

It's important to know that you can specify some standard value:

• guest : isn't a group of your system, is a standard for the plugin to understand which page can access user that isn't logged in.
• character *: This character specify that this group can access to all views of this controller

if you omitt some user group or for example user guest, means that the user group, or guest can't access to any page of this controller.

Views

This parameter is an array of callback function. Example:

In this case you have specify that: if the next page is edit the plugin check if that user can access to that page with array groups, after if the user can access to that page call the function with the name that you have passed. This function must be to return a true or false value. If return true the user can access to that page, if false can't access to it. The function that you call must be inside the controller where you call the plugin function, have to be the same name that you passed into the string and must be to return a value true or false.

Example:

In this case there are two callbacks function: checkEdit and checkDelete.

If you are into the page add these function aren't called. But if you try to access to the page edit, after understand if the user can access to that page by groups array, the plugin call checkEdit function. This function compare id of the user logged and the id passed by get: means that only the same user can access to that page. if you try to accss to the edit page of another user return an error and you redirect to another page. Same thing to the page delete and the function checkDelete().
