代码点火器4-验证消息未正确显示

Question

我决定将验证和消息放入HunterModel.php模型中。HunterController.php文件中的createHunter()方法应该插入一条记录。

下面的片段显示了我遇到的问题：显然$this->$data->listError();没有显示我在$validationMessages中定义的消息。

• HunterModel.php

// Validation
protected $validationRules      = [
'name_hunter' => 'required|max_length[30]',
'age_hunter' => 'required|integer',
'height_hunter' => 'required|decimal',
'weight_hunter' => 'required|decimal',
'type_hunter' => 'required|max_length[30]',
'type_nen' => 'required|max_length[30]',
'type_blood' => 'required|max_length[3]'
];
protected $validationMessages   = [
'name_hunter' => [
'required' => 'Hunter name cannot be empty.',
'max_length' => 'The hunter name must have a maximum of 30 characters.'
],
'age_hunter' => [
'required' => 'Hunter age cannot be empty.',
'integer' => 'The hunter's age must be an integer.'
],
'height_hunter' => [
'required' => 'Hunter height cannot be empty.',
'decimal' => 'The hunter height must be a decimal number.'
],
'weight_hunter' => [
'required' => 'Hunter weight cannot be empty.',
'decimal' => 'The hunter weight must be a decimal number.'
],
'type_hunter' => [
'required' => 'It is necessary to define the type of hunter.',
'max_length' => 'The hunter type must be a maximum of 30 characters.'
],
'type_nen' => [
'required' => 'It is necessary to define the nen of the hunter.',
'max_length' => 'The hunter's nen must have a maximum of 30 characters.'
],
'type_blood' => [
'required' => 'It is necessary to define the hunter's blood type.',
'max_length' => 'The hunter's blood type must be a maximum of 3 characters.'
]
];

• HunterController.php

public function createHunter()
{
try {
$hunter = new HunterModel();
$data = [
'name_hunter' => $this->request->getPost('name_hunter'),
'age_hunter' => $this->request->getPost('age_hunter'),
'height_hunter' => $this->request->getPost('height_hunter'),
'weight_hunter' => $this->request->getPost('weight_hunter'),
'type_hunter' => $this->request->getPost('type_hunter'),
'type_nen' => $this->request->getPost('type_nen'),
'type_blood' => $this->request->getPost('type_blood')
];
if ($hunter->insert($data)){
return $this->response->redirect(site_url('/read_hunters'));
} else {
$this->$data->listError();
}
} catch (Exception $e) {
exit($e->getMessage());
} 
}

在Libraries文件夹中创建Validations.php(如果不存在(。

Validations.php必须类似于：

<?php
namespace AppLibraries;
class Validations
{
public $hunter = [
'rules' => [
'name_hunter' => 'required|max_length[30]',
//other rules...
],
'error' => [
'name_hunter' => [
'required' => 'Hunter name cannot be empty.',
'max_length' => 'The hunter name must have a maximum of 30 characters.'
],
//other error messages....
]
];
}

HunterController.php必须类似于：

<?php
namespace AppControllers;
use AppLibrariesValidations;
class HunterController extends BaseController
{
public function __construct()
{
$this->validator = new Validations();
}
public function createHunter()
{
$response = [];
$val = $this->validate(
$this->validator->hunter['rules'],
$this->validator->hunter['error']
);
if (!$val) {
$response = [
'success' => false,
'msg' => addslashes((preg_replace('/s+/', ' ', $this->validation->listErrors())))
];
}else {
try {
$hunter = new HunterModel();
$data = [
'name_hunter' => $this->request->getPost('name_hunter'),
'age_hunter' => $this->request->getPost('age_hunter'),
'height_hunter' => $this->request->getPost('height_hunter'),
'weight_hunter' => $this->request->getPost('weight_hunter'),
'type_hunter' => $this->request->getPost('type_hunter'),
'type_nen' => $this->request->getPost('type_nen'),
'type_blood' => $this->request->getPost('type_blood')
];
if ($hunter->insert($data)){
return redirect()->to(site_url('/read_hunters'));
} else {
$response = [
'success' => false,
'msg' => //your custom error message
];
}
} catch (Exception $e) {
exit($e->getMessage());
} 
//if you are using ajax
return $this->response->setJSON($response);
}
}
