Codeigniter 4模块表单操作

Question

我正在遵循Codeigniter 4.0.4用户指南和创建模块。我已经创建了博客模块，页面加载正确(索引，视图，创建)。

我在创建页面上遇到了麻烦，表单操作调用的是应用程序/控制器，而不是位于应用程序文件夹外的模块控制器。我使用两个助手(表单，网址)。

我的路线

$routes->group('myblog', ['namespace' => 'Acme\MyBlog\Controllers'], function($routes)
{
    $routes->get('/', 'MyBlog::index');
    $routes->get('view', 'MyBlog::view');
    $routes->get('create', 'MyBlog::create');
});

我的自动加载

public $psr4 = [
    APP_NAMESPACE   => APPPATH, // For custom app namespace
    'App'           => APPPATH,
    'Config'        => APPPATH.'Config',
    'Acme\MyBlog'   => ROOTPATH.'Acme\MyBlog'
];

我的控制器

<?php namespace Acme\MyBlog\Controllers;

use Acme\MyBlog\Controllers\BaseController;

use Acme\MyBlog\Models\PostModel;

use CodeIgniter\I18n\Time;


class MyBlog extends BaseController 
{

    public function create() 
    {
        $model = new PostModel();
        
        if ($this->request->getMethod() === 'post' && $this->validate([
            'title' => 'required|min_length[3]|max_length[255]',
            'body'  => 'required'
        ])) 
        {
            $model->save([
                'title' => $this->request->getPost('title'),
                'slug'  => url_title($this->request->getPost('title'), '-', TRUE),
                'body'  => $this->request->getPost('body'),
            ]);
                        echo view('Acme\MyBlog\Views\success');
        } 
        else 
        {
            echo view('Acme\MyBlog\Views\create', ['title' => 'Create a news Post']);
        }
    }
}

我的创建表单

<h2><?= esc($title); ?></h2>
<?= \Config\Services::validation()->listErrors(); ?>
<div>
    <div>
        <?php echo form_open('myblog/create'); ?>
            <?= csrf_field() ?>
            <?php echo form_label('What is the Title', 'title');
            echo form_input('title') . '<br />'; 
            echo form_label('Post Body', 'body');
            echo form_textarea('body') . '<br />';            
            echo form_submit('submit', 'Create News Post!');
            $string = '</div></div>';
            echo form_close($string); ?>

表单操作被设置为myblog/create，created的html也显示了这一点

// THE HTML CREATED 
<div>
    <div>
        <form action="http://localhost:8080/myblog/create" method="post" accept-charset="utf-8">
            <input type="hidden" name="csrf_test_name" value="7b9750243204e5a0578a74cec6b42b77" />
            <label for="title">What is the Title</label><input type="text" name="title" value=""  />
            <br />
            <label for="body">Post Body</label><textarea name="body" cols="40" rows="10" ></textarea>
            <br />
            <input type="submit" name="submit" value="Create News Post!"  />
        </form>
    </div>
</div>

然而，当我尝试提交表单时，我得到了以下错误。这个控制器是从哪里调用的？

<div class="wrap">
    <h1>404 - File Not Found</h1>
    <p>Controller or its method is not found: \App\Controllers\Myblog::create</p>
</div>

谢谢你的帮助。

您需要将代码从$routes->get('create', 'MyBlog::create');更改为$routes->post('create', 'MyBlog::create');
