Question

我的Codeigniter控制器中$_POST变量始终为空：

controllers / Register.php

class Register extends CI_Controller 
{

    public function index()
    {

        $this->load->view('register.html');

    }

    public function user()
    {
        var_dump($_POST);

    }

}

views / register.html（查看）

<form method="post" role="form" action="register/user">
    <div class="form-group">
        <label for="email">Name:</label>
        <input type="text" class="form-control" id="name">
    </div>
    <div class="form-group">
        <label for="email">Email address:</label>
        <input type="email" class="form-control" id="email">
    </div>

    <div class="form-group">
        <label for="pwd">Password:</label>
        <input type="password" class="form-control" id="pwd">
    </div>

    <div class="checkbox">
        <label><input type="checkbox"> Remember me</label>
    </div>

    <button type="submit" class="btn btn-default">Submit</button>
</form>

这是我的.htaccess，我正在使用它从我的网址中删除index.php。

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

var_dump($_POST)始终输出array(0) { }，但$_GET正常。我在Linux（Arch）上使用Apache，Codeigniter 3和PHP 7。

抱歉我的英文。谢谢大家。

编辑：

$this->input->post()也是空的。

Answer 1

The main cause is name attributes from all the form-elements are missing

Like for example:-

<input type="text" class="form-control" id="name">

It seems you confused between id and name.

name is the attribute picked-up by $_POST.

全局POST总是空的
