我正在尝试构建一个简单的登录表单，如youtube视频中所示。在视频中，我的登录表单应该张贴信息，而不是获取信息，正如你在制造商重定向到的url中看到的那样。
然而，我的CodeIgniter总是在提交登录信息并重定向到以下示例链接后获取信息：
http://localhost/CodeIgniter/?email=member%40backupbull.com&password=password13&login_submit=Login
表单帮助程序自动加载到CodeIgniter中。
控制器：
public function login()
{
$this->load->view('login');
}
public function login_validation()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('email','Email','required');
$this->form_validation->set_rules('password','Password','required|md5');
if($this->form_validation->run()){
redirect('pages/members');
} else {
$this->load->view('login');
}
}
public function members(){
$this->load->view('members');
}
视图（login.php）：
<?php $this->load->view('site_template/header.php'); ?>
<body>

我不知道如何解决这个问题。
提前感谢您的帮助！
form_open()函数位于表单标记之间。
<form class="navbar-form pull-right"> <!-- getting submitted with the default GET method -->
<?php
echo form_open('pages/login_validation');
//form inputs
echo form_close();
?>
</form>
所以，正在提交的表格是外部的。
删除那些表单标签，它应该可以工作了。
form_open创建了一个<form>标记（使用POST方法），但您在其前面使用：
<form class="navbar-form pull-right">
这一个没有方法属性，这使它默认为GET。
你好，尝试强制POST
echo form_open('pages/login_validation', array('method'=> 'POST'));
