Question

我做了一个简单的项目，用户可以注册他的帐户，使用他的凭据登录，查看他的博客文章并创建一个新的博客。我目前正在创建一个新博客，这个简单的表单有两个选项：博客标题和内容。我遇到了你点击提交的部分，表单被传递给form_open函数中指定的控制器。点击提交按钮时没有发生任何事情，这就是问题所在。

这是我的观点文件：

    <head>
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7" crossorigin="anonymous">
        <meta charset="utf-8">
        <title>Enter your Title</title>
    </head>
    <body>
        <div class="container">
            <div class="jumbotron">
                <?=form_open("blog/submitpost"); ?>
                <div class="form-horizontal">
                    <div class="form-group">
                        <label for="blogtitle" class="control-label col-sm-2">Blog Title</label>
                        <div class="col-sm-8">
                            <input type="text" name="blogtitle" placeholder="Enter your title here" class="form-control">
                        </div>
                    </div>

                    <div class="form-group">
                        <label for="blogdesc" class="control-label col-sm-2">Blog Title</label>

                        <div class="col-sm-8">
                            <textarea name="blogdesc" rows="8" cols="40" class="form-control" placeholder="Enter your post here"></textarea>
                        </div>
                    </div>
                </div>
            <?=form_close();?>
            <div style="text-align: center;">
                <button type="submit" name="submit" class="btn btn-success">Submit</button>
            </div>
            </div>
        </div>

    </body>
</html>

这是我的控制器

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Blog extends CI_Controller{

    function __construct(){
        parent::__construct();
        $this->load->model('user');
        $this->load->helper('form');
    }


    public function new_post($id){
        $data['id'] = $id;
        $this->load->view('blog_new_post',$data);
    }

    public function blogpostview($id){
        $session_data = $this->session->userdata('logged_in');
        $data['username'] = $session_data['username'];
        $data['id'] = $id;
        $data['posts'] = $this->user->blog_post_list($data['username']);
        $this->load->view('blog_view',$data);
    }

    public function submitpost(){
      //there will be additional code here
        $this->load->view('blog_post_view');
    }

}
?>

现在首先，我知道必须加载Form帮助程序类来实现这一点，我已经完成了。我甚至更改了autoload.php文件以自动加载它。

其次，我已经在注册和登录过程中实现了两次。但是这次我不知道为什么代码不起作用。

好的，我得到了解决方案，这是一个非常简单的解决方案。我没有在表单中放置提交按钮，因为问题来了！有时它是最简单的解决方案。
