CodeIgniter - displaying success or unsuccess message
提问by BigJobbies
Im wondering if someone could let me know how they handle success / unsuccess messages in CodeIgniter.
我想知道是否有人可以让我知道他们如何处理 CodeIgniter 中的成功/不成功消息。
For example, what im doing at the moment when a user signs up to my site, this is what happens in the controller
例如，当用户注册我的网站时我在做什么，这就是控制器中发生的事情
if (!is_null($data = $this->auth->create_user( $this->form_validation->set_value('username'), $this->form_validation->set_value('password') ))) {
// Redirect to the successful controller
redirect( 'create-profile/successful' );
} else {
// Redirect to the unsuccessful controller
redirect( 'create-profile/unsuccessful' );
}
Then in the same controller (create-profile), i have 2 methods which are like the following
然后在同一个控制器（创建配置文件）中，我有两种方法，如下所示
function successful()
{
$data['h1title'] = 'Successful Registration';
$data['subtext'] = '<p>Test to go here</p>';
// Load the message page
$this->load->view('message',$data);
}
The problem with this is that i can simply go to site.com/create-profile/successful and it will show the page.
问题在于，我可以简单地访问 site.com/create-profile/successful，它会显示该页面。
If someone could possibly show me a better way of handling this, it would be greatly appreciated.
如果有人可以向我展示处理此问题的更好方法，将不胜感激。
Cheers,
干杯，

You could set a flashdatabefore the redirection:
您可以在重定向之前设置flashdata：
$this->session->set_flashdata('create_profile_successful', $some_data);
redirect( 'create-profile/successful' );
function successful(){
if( FALSE == ($data = $this->session->flashdata('create_profile_successful'))){
redirect('/');
}
$data['h1title'] = 'Successful Registration';
$data['subtext'] = '<p>Test to go here</p>';
// Load the message page
$this->load->view('message',$data);
}

is there a reason you don't use this:
你有什么理由不使用这个：
if (!is_null($data = $this->auth->create_user( $this->form_validation->set_value('username'), $this->form_validation->set_value('password') ))) {
$data['h1title'] = 'Successful Registration';
$data['subtext'] = '<p>Test to go here</p>';
// Load the message page
$this->load->view('message',$data);
} else {
$data['h1title'] = 'Unsuccessful Registration';
$data['subtext'] = '<p>Test to go here</p>';
// Load the message page
$this->load->view('message',$data);
}

Instead of redirecting, just show different views.
而不是重定向，只是显示不同的视图。
Here is some sample code:
下面是一些示例代码：
if ($this->input->server('REQUEST_METHOD') == 'POST')
{
// handle form submission
if (!is_null($data = $this->auth->create_user( $this->form_validation->set_value('username'), $this->form_validation->set_value('password') )))
{
// show success page
$data['h1title'] = 'Successful Registration';
$data['subtext'] = '<p>Test to go here</p>';
// Load the message page
$this->load->view('message',$data)
}
else
{
// show unsuccessful page
$data['h1title'] = 'Unsuccessful Registration';
$data['subtext'] = '<p>Test to go here</p>';
// Load the message page
$this->load->view('message',$data)
}
}
else
{
// show login page
$data['h1title'] = 'Login';
$data['subtext'] = '<p>Test to go here</p>';
// Load the message page
$this->load->view('login',$data)
}
