Re-routing execution to a different controller

[eluser]philmctim[/eluser]
Say I have the following:

1) An page that lists all the rows in a table. It has an 'insert' button that takes you to...

2) A form page that lets you enter a new value in the table.

I would like the 'success' page of (2) to take the user back to (1). So once the validation is complete and the row is inserted, I want to re-direct the control flow to a different controller function (the two controller functions may be in different controller files).

Any tips?

Thanks.

If I understand your problem correctly, I think you want (2) to pass a message to (1).

I would put something like the following in the view of (1):

Code:

&lt;?=isset($message) ? '<div id="alert">' . $message . '</div>' : ''?&gt;

And then I would have the controller function of (1) look like this:

Code:

function displaystuff($message = '') {
  //get ready to display the rows of the table
  ...

  $data['message'] = $message;
  ...
  $this->load->view(..., $data);
}

And the function of the form like this:

Code:

function process_data() {
  //process the POST input
  ...

  //send the success message
  $this->displaystuff('The form was successfully processed');
}

I know this works when both functions are in the same controller. I am not sure it will work when they are separate controllers.

Hope this helps

It's usually best to handle messages with session flashdata, this way you can simply redirect them, via the redirect() function, and still rely on message info to be available after a new HTTP request

Thanks, I'll give it a try.
