我正在使用 CodeIgniter 4 和 SQL 数据库制作联系表单。表单将通过按钮提交,因此每当单击它时,它就会验证,如果填写了所有字段,则显示消息并将信息保存到数据库时没有问题,但是当字段为空时,它不显示错误消息,并且继续指出该文件不存在。
好吧,我现在被错误消息困住了。我不确定代码有什么问题。我是不是错过了什么?
以下是我的代码:
应用程序/config/Routes.php
$routes->get('contact', 'Contact::contact');
$routes->post('contact/save', 'Contact::save');
应用程序/控制器/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');
}
}
}
}
应用程序/视图/page_templates/contact.php
<form action="<?= base_url('contact/save'); ?>" method="post" role="form" class="php-email-form">

<textarea class="form-control" name="content" rows="5" wrap="hard" placeholder="Message"></textarea>
<span class="text-danger"><?= isset($validation) ? display_error($validation, 'content') : '' ?></span>
</div>
<div style="height: 10px;"></div>
<div class="text-left button">
<button type="submit" name="submit">Send Message</button>
</div>
<div style="height: 10px;"></div>
</form>
好的,我已经用我的代码解决了这个问题。这确实是一个小错误,或者我可以说是粗心的错误,哈哈现在感觉很愚蠢,但我需要改变并使其发挥作用。
这部分是:
return view('contact', ['validation' => $this->validator]);
我实际上没有这样做,而是错过了正确放置文件来调用视图页面的机会,因此我只添加了文件夹名称
页面模板
如果我将其包含在代码中,它应该如下所示:-
return view('page_template/contact', ['validation' => $this->validator]);
然后就可以了哈哈。
