Exiting the application - simple issue - El Forum - 06-20-2008

Hello,
I need to check for something in my Controller constructor and if the condition is met, I need display a view and exit the application.
if (1 == 1)
{
$this->load->view('closed', $this->data);
exit;
}
The code above is showing a blank page.
Please help.

I think you should only load a view and quit the exit function because CI will never renders the final output.
Also, you can use $this->output->set_output($any_text_or_html) in order to display any message.

Hi,
If I remove the exit function the rest of the code will be executed
I just need to show the view called 'closed'

Enclosed rest of code with an else sentence can be a solution

I thought about that but it's not logical at all.
What if the visitor supply a method name that do exist? It will be executed unless I put my code in every method I have!!!

You could try using "return;" instead of "exit;".

Maybe putting this in your controller:
Code:
function _remap($method)
{
if (1 == 1)
{
$this->load->view(’closed’, $this->data);
return false;
}
else
{
if (!method_exists($this, $method))
{
show_404();
}
return call_user_func_array(array(&$this, $method), array_slice($this->uri->rsegments, 2));
}
}Of course, you must change 1 == 1 for your logic.

It won't work because of CI's output buffering. Try this:
Code:
ob_start();
$this->load->view('closed', $this->data);
ob_end_flush();
exit();Exiting the application - simple issue - El Forum - 06-20-2008

I am using it and, as far as I know, it works. Can you say me where is the error?
Thanks.
