CodeIgniter 4 错误验证未读取

Question

我正在使用 Codeigniter 4 和 SQL 数据库制作联系表。表单将通过按钮提交，因此无论何时单击它，它都在验证，如果所有字段都已填写，则显示消息并将信息保存到数据库没有问题，但是当字段为空时，它不显示错误消息，并继续声明该文件不存在。

好吧，我现在被错误消息困住了。我不确定代码有什么问题。我错过了什么吗？

有人可以帮我解决这个问题吗？我很感激我能得到的所有帮助。

下面是我的代码：

App/config/Routes.php

$routes->get('contact', 'Contact::contact');
$routes->post('contact/save', 'Contact::save');

App/Controller/Contact.php

 <?php

namespace App\Controllers;

use App\Models\ContactModel;

class Contact extends BaseController
{

    public function __construct()
    {
        helper(['url', 'form']);
    }

    //CONTACT PAGE
public function contact()
{

    $data = [
        'meta_title' => 'Contact | MFD',
    ];

    return view('page_templates/contact', $data);
}

//SAVE
public function save()
{

    $validation = $this->validate([
        'name' => [
            'rules' => 'required',
            'errors' => [
                'required' => 'Your full name is required'
            ]
        ],
        'email' => [
            'rules' => 'required|valid_email|is_unique[users.email]',
            'errors' => [
                'required' => 'Email is required',
                'valid_email' => 'You must enter a valid email',
            ]
        ],
        'title' => [
            'rules' => 'required',
            'errors' => [
                'required' => 'Title is required',
            ]
        ],
        'content' => [
            'rules' => 'required',
            'errors' => [
                'required' => 'Content is required',
            ]
        ],
    ]);


    if (!$validation) {
        return view('contact', ['validation' => $this->validator]);
    } else {

        // Let's Register user into db
        $name = $this->request->getPost('name');
        $email = $this->request->getPost('email');
        $title = $this->request->getPost('title');
        $content = $this->request->getPost('content');

        $values = [
            'name' => $name,
            'email' => $email,
            'title' => $title,
            'content' => $content,
        ];

        $contactModel = new ContactModel();
        $query = $contactModel->insert($values);
        if ($query) {
            return redirect()->to('contact')->with('success', 'Your message are successful sent');
        } else {
            return redirect()->to('contact')->with('fail', 'Something went wrong');
        }
    }
}

}

好的，我已经解决了我的代码的问题。这真的是一个小错误，或者我可以说是粗心的错误哈哈现在感觉很愚蠢，但我需要改变并让它发挥作用。

这部分是：return view('contact', ['validation' => $this->validator]); 我没有像那样做，而是错过了放置文件以正确调用视图页面的代码，所以我只添加了我的文件夹名称

page_templates

如果我将它包含在代码中，它应该如下所示：-

return view('page_template/contact', ['validation' => $this->validator]);

然后就可以了哈哈
