Mini Program _ ThinkPHP_2
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.
