01.我们在View目录中,创建一个登陆的php网页,代码如下:
<!doctype html> <html> <head> <title>10年CI一场梦</title> </head> <body> <form action="<?php echo $POST_URL; ?>" method="post" enctype="multipart/form-data"> <p>账号: <input type="text" name="username"/></p> <p>密码: <input type="text" name="password"/></p> <input type="submit" name="submit" value="确定"/> </form> </body> </html>
02.我们在控制器中添加表单验证类,代码如下:
<?php namespace AppControllers; // http://127.0.0.1/CI4/public/index.php/hello/ class Hello extends BaseController { public function __construct() { $this->validation = ConfigServices::validation(); //加载表单验证类库 helper(['form', 'url']); } public function index() { //判断是否有提交内容过来 if (!empty($this->request->getPost("submit"))) { $this->validation->setRules([ 'username' => [ 'label' => '账号', 'rules' => 'required', 'errors' => [ 'required' => '{field} 不能为空!' ] ], 'password' => [ 'label' => '密码', 'rules' => 'required|min_length[10]', 'errors' => [ 'min_length' => '你的 {field} 太短了!' ] ] ] ); if ($this->validation->withRequest($this->request)->run()) { echo '按钮: ' . $this->request->getPost("submit") . '<br>'; echo '账号: ' . $this->request->getPost("username") . '<br>'; echo '密码: ' . $this->request->getPost("password") . '<br>'; } else { $errors = $this->validation->getErrors(); ShowMessage($errors); } } //显示View页面 $data = array('POST_URL' => base_url('public/index.php/hello/'),); echo view('login/login', $data); } }
03.我们用浏览器访问http://localhost/CI4/public/index.php/hello,2个表单输入的内容如果不满足表单验证内容,那么现实的效果如下:
