Codeigniter how to set form action url using form_open helper function
提问by
I am using Codeigniter with Bootstrap. This is my view code:
我正在使用带有 Bootstrap 的 Codeigniter。这是我的视图代码：
<?php echo form_open('con_login/loginUser'); ?>
<div class="bs-example">
<div class="col-md-2">
<label class="sr-only" for="username">Username</label>
<input type="text" class="form-control" name="username" placeholder="Username" value="">
</div>
<div class="col-md-2">
<label class="sr-only" for="password">Password</label>
<input type="password" class="form-control" name="password" placeholder="Password" value="">
</div>
<button type="submit" class="btn btn-default" name="login" value="login">Sign in</button>
</div>
<?php echo form_close(); ?>
The code for the called function which is in the controller is:
控制器中被调用函数的代码是：
public function loginUser() {
$username = $this->mod_login->getUsername();
$inUser = $this->input->post('username');
$inPass = $this->input->post('password');
if (in_array($inUser, $username)) {
$password = $this->mod_login->getPassword($inUser);
if ($password === $inPass) {
$this->load->view('Alt_home');
}
}
}
But I get the error
但我得到了错误
The requested URL /SEP/con_login/loginUser was not found on this server.
在此服务器上找不到请求的 URL /SEP/con_login/loginUser。
Why is this? Is there anything to do with Routing?
为什么是这样？和路由有关系吗？

You will need to pass complete url to the form_open function like this
您需要像这样将完整的 url 传递给 form_open 函数
<form action='http://localhost/folder/controller/method'>
There are two method to do this
有两种方法可以做到这一点
1: Using base_url()
1：使用 base_url()
Step 1: Open the config.php file under application\config folder
第一步：打开application\config文件夹下的config.php文件
step 2: Set the value of $config['base_url']to your website path
第 2 步：将 的值设置$config['base_url']为您的网站路径
$config['base_url'] = "http://localhost/foldername/index.php";
How to use

Load the url helper in controller
在控制器中加载 url helper
$this->load->helper('url);
Now in the view file you can use like this

did you load helper (url,form) in your controller if not then u should make a load function in your controller just like this
您是否在控制器中加载了 helper (url,form) 如果没有，那么您应该像这样在控制器中创建一个加载功能
public function load(){
$this->load->helper('url');
$this->load->helper('form');
}
and use this in function
并在功能中使用它
public function loginUser() {
$this->load();
$username = $this->mod_login->getUsername();
$inUser = $this->input->post('username');
$inPass = $this->input->post('password');
if (in_array($inUser, $username)) {
$password = $this->mod_login->getPassword($inUser);
if ($password === $inPass) {
$this->load->view('Alt_home');
}
}
}

You can use like this, Its works for me.. lets see if it is works for you or not. If you don't want attributes remove from second argument of form_open() function.
你可以这样使用，它对我有用..让我们看看它是否适合你。如果您不想从 form_open() 函数的第二个参数中删除属性。
<?php $attributes = array('class' => 'myformclass', 'id' => 'myformid','name' => 'myformname');
echo form_open(base_url("con_login/loginUser"),$attributes);?>
HTML HERE
此处为 HTML
<?php echo form_close();?>
Thank You
谢谢
