Slim框架从表单中获取数据

Question

我尝试使用SLIM框架制作一个简单的表单.我不知道如何显示发布的数据.我想试着回应它.我听说我需要使用额外的库RESPECT,我认为SLIM可以做这么小的事情.

这是我的代码:

require '../../vendor/slim/slim/Slim/Slim.php';
\Slim\Slim::registerAutoloader();
$app = new \Slim\Slim();

$app->get('/', function() use ($app){
    $app->render('form.php');
});

$app->post('/', function() use ($app){
    $req = $app->request();
    $errors = array();
    $params = array(
        'email' => array(
            'name'=>'Email',
            'required'=>true,
            'max_length'=>64,
        ),
        'subject' => array(
            'name'=>'Subject',
            'required'=>true,
            'max_length'=>256,
        ),
      );
        //submit_to_db($email, $subject, $message);
        $app->flash('message','Form submitted!');

    $app->redirect('./');
});

$app->run();

在Slim 2中,您可以使用以下post()方法访问发布的数据request():

$app->post('/', function () use ($app) {
    $request = $app->request();
    $email = $request->post('Email');
    $subject = $request->post('Subject');
    echo "Email: $email<br/>";
    echo "Subject: $subject";
});

在Slim 3中,请求被传递给回调/控制器/等.并且您可以调用getParam()从body或查询字符串中获取值(按此顺序):

$app->post('/', function ($request, $response, $args) {
    $email = $request->getParam('Email');
    $subject = $request->getParam('Subject');
    echo "Email: $email<br/>";
    echo "Subject: $subject";
});

从开始修身3.1也有getParsedBodyParam()和getFetchParam()只从身体或查询字符串获取.(PR#1620)

提醒一下,您可以提供默认值: $request->getParam('Email', 'default_value')
