CodeIgniter - >将表单提交到数据库中

Question

创建我自己的应用程序以学习CodeIgniter，通过遵循CI文档，我无法将数据发布到db。

我正在使用create.php：

<p class="h4 mb-4 text-center"><?= $title ?></p>

<label>Username</label>
<input type="text" id="textInput" class="form-control mb-4" placeholder="Your username" name="username">

<label for="textInput">Title</label>
<input class="form-control mb-4" placeholder="Your title" name="title">

<label>Your message</label>
<textarea class="form-control mb-4" placeholder="Your message content" name="body"></textarea>
<div class="row">
    <div class="col-8">
    <select class="browser-default custom-select mb-4" id="select" name="genre">
        <option selected="">Choose your Genre</option>
        <option value="1">Male</option>
        <option value="2">Female</option>
    </select>
    </div>
    <div class="col-2">
        <input class="form-control mb-4" placeholder="Your age" name="age">
    </div>
</div>
<select class="browser-default custom-select mb-4" name="platform">
    <option value="" disabled="" selected="">Choose your Platform</option>
    <option value="1">Snapchat</option>
    <option value="2">Kik</option>
    <option value="3">Instagram</option>
    <option value="4">Telegram</option>
</select>

<button class="btn btn-info my-4 btn-block" type="submit">Sign up</button>

<div class="text-center">
    <p>By clicking
        <em>Sign up</em> you agree to our
        <a href="<?php echo base_url('tou'); ?>" target="_blank">terms of use</a>.
    </p>
</div>

这是控制器：

public function create(){
        $data['title'] = 'Add your Username';

        $this->form_validation->set_rules('title', 'Title', 'required');
        $this->form_validation->set_rules('body', 'Body', 'required');
        $this->form_validation->set_rules('username', 'Username', 'required');
        $this->form_validation->set_rules('genre', 'Genre', 'required');
        $this->form_validation->set_rules('platform', 'Platform', 'required');
        $this->form_validation->set_rules('age', 'Age', 'required');

        if($this->form_validation->run() === FALSE){
            $this->load->view('templates/header');
            $this->load->view('posts/create', $data);
            $this->load->view('templates/footer');
        } else {
            $this->post_model->create_post();
            redirect('posts');
        }
    }

这是模型：

public function create_post(){
        $slug = url_title($this->input->post('title'));

        $data = array(
            'title' => $this->input->post('title'),
            'slug' => $slug,
            'body' => $this->input->post('body'),
            'username' => $this->input->post('username'),
            'genre' => $this->input->post('genre'),
            'age' => $this->input->post('age'),
            'platform' => $this->input->post('platform'),
        );
        return $this->db->insert('posts', $data);
    }

我也在autoload（libraries-> form_validation）和（helper-> form）中添加了。我已经在这些代码之前测试了所有内容，并且工作正常。问题是HTML中的那些数据我想将它们发送到数据库中，但即使验证器在空白表单上工作（提交没有内容）或插入内容，它只是在实现页面，因为它应该将其重定向到帖子URL。有人可以帮帮我吗？

Answer 1

你的帖子方法在哪里？

例如：

<form method="post" name="from_submit" action="">

Answer 2

你忘了添加表格

 <form method="post" name="myform" action="">
//Your form code---

</form>
