This article mainly introduces the relevant knowledge of how to use R method in thinkphp, the content is detailed and easy to understand, the operation is simple and fast, and it has a certain reference value. I believe you will gain something after reading this thinkphp article on how to use R method. Let's take a look at it.

In thinkphp, the R method is used to call the operation method of a controller, which is a further enhancement and supplement to the A method. The calling format of the R method is "R ('[project: / /] [grouping /] module / operation', 'parameter', 'controller layer name')".

How to use R method in thinkphp

The R method is used to call the operation method of a controller and is a further enhancement and supplement of the A method.

The calling format of the R method:

R ('[project: / /] [grouping /] module / operation', 'parameter', 'controller layer name')

For example, we define a method of operation as follows:

Class UserAction extends Action {public function detail ($id) {return M ('User')-> find ($id);}}

Then this operation method can be called in other controllers through the R method (usually the R method is used for cross-module calls)

$data = R ('User/detail',array (' 5'))

Indicates that the detail method of the User controller is called (the detail method must be of type public), and the returned value is a user data that queries for an id of 5. If the operation method you want to call does not have any parameters, you can leave the second parameter blank and use it directly:

$data = R ('User/detail')

You can also support cross-grouping and project calls, such as:

R ('Admin/User/detail',array (' 5'))

Indicates that the detail method of the User controller under the Admin grouping is called.

R ('Admin://User/detail',array (' 5'))

Indicates that the detail method of the User controller under the Admin project is called.

The official suggestion is not to make too many calls in the same layer, which will cause logic confusion. The parts that are called by the public should be encapsulated into separate interfaces. With the help of the new multi-layer controller of 3.1, we can add a separate controller layer for interface calls. For example, we add an Api controller layer.

Class UserApi extends Action {public function detail ($id) {return M ('User')-> find ($id);}}

Then, use the R method to call

$data = R ('User/detail',array (' 5'), 'Api')

That is, the third parameter of the R method supports the specified controller layer for the call.

At the same time, the R method can support the operation suffix setting C ('ACTION_SUFFIX') when calling the operation method. If you set the action method suffix, you still do not need to change the way the R method is called.
