Build verification layer

Download a tp5 framework file to xampp\ htdocs and rename it to zerg (server), then open a new project with PhpStorm, open a new api folder module under the application directory, then create a new controller folder, create a new v1 folder under controller, and then create a new Banner.php (Controller layer) with a new method getBanner (Action action):

Class Banner

{

Public function getBanner () {

}

}

1. Straightforward verification:

(1) TP5 transmission parameter method

Public function getBanner ($id) {

$data = [

'id' = > $id

]

$validate = new Validate (['id' = >' require | max:2' / / indicates that the id parameter must be no more than 2 characters long]); $result = $validate- > check ($data); if (! $result) {echo $validate- > getError ();} else {echo "success";}

}

The test results are as follows:

(2) the method of obtaining all parameters by Request:

The result is the same:

$validate = new Validate ([

'id' = >' require | max:2'

])

$request = Request::instance ()

$result = $validate- > check ($request- > param ())

If (! $result) {

Echo $validate- > getError ()

} else {

Echo "success"

}

two。 Object-oriented verification:

Mode 1 (prototype)

Create a new validate under api, and create a new php file IDMustBePositiveInt.php that inherits from Validate. Add the following code

Protected $rule = [

'id' = >' require | isPositiveInteger', / / add a custom verification method isPositiveInteger

]

Protected function isPositiveInteger ($value, $rule ='', $data ='', $field =') {if (is_numeric ($value) & & is_int ($value+0) & & ($value+0) > 0) {return true;} else {return $field. 'must be a positive integer';}}

The results are as follows:

Mode 2 (final version)

Create a new BaseValidate.php file (controller) under validate and inherit from Validate, and add a custom method goCheck ()

Then let isMusBePositiveInt inherit with Validate

Then all you need is one sentence in Banner.

Test result

Object-oriented programming is not only less code but also reusable, so it needs to be mastered well.
