Re: Passing data to controller action based on button clicked

You could also forgo the hidden fields, and just grab the needed ID at the time of redirect:
eg.
 if($this->data['Submit'] == 'Previous){
  $this->redirect(array('controller' => 'drugs', 'action' => 'view', $this->Drug->getPrevious($id));
 }

But with the first approach, you would have the information available as to whether there actually was a next or previous item, and not display the button if there wasn't.

Off the top of my head, here is what I would do:

1. In the edit function, grab the IDs for the previous and next items. I would probably have two methods in the model, getNext($id) and getPrevious($id), or something like that, which return the IDs for the next and previous items, respectively. Then you can do $this->set('previous', $this->Drug->getPrevious($id)); and $this->set('next', $this->Drug->getNext($id));
 
2. In your edit view, have two hidden fields:
 echo $this->Form->hidden('Drug.next_id', array('value'=>$next));
 echo $this->Form->hidden('Drug.previous_id', array('value'=>$previous));

3. Your buttons:
 echo $this->Form->submit('Save', array('name' => 'Submit')); 
 echo $this->Form->submit('Previous', array('name' => 'Submit')); 
 echo $this->Form->submit('Next', array('name' => 'Submit')); 

4. In your edit function, save the data, then check for which button was pushed, and redirect to the appropriate place. I wasn't sure if you wanted the previous and next to go to the edit views of those or not:
 if($this->data['Submit'] == 'Previous){
  $this->redirect(array('controller' => 'drugs', 'action' => 'view', $this->data['Drug']['previous_id']));
 } else {
 ..... etc
 
I think this works, and seems a bit cleaner than your approach. Like I said, it's off the top of my head, so there may be some small bits which need massaging.

In my app I have an edit view; the view has a standard save button. I
would like to  have a save, previous, and next button. I have the
controller actions done to move to the next and previous item, but I
don't know how to pass the data to it from the edit view/controller.
Right now if I click the previous or next button it just does the
standard save. So I tried this:

    echo $this->Form->submit('Save', array('name'=>'save');
    echo $this->Form->submit('Save & Next', array('name'=>'savenext');

//In the controlller edit function
    if (isset($this->params['form']['submit']) && $this->params['form']
['submit'] == "savenext") {
      // Save and next button Clicked
    }

I would like for it save the edit and move to the next item. I also
tried calling the function directly and passing it the data like so:
$this->next($id,$generic), but it doesn't have the rest of the data so
it won't save. If I passed the function $this->data, would it work
correctly? I changed the buttons to links just to be sure it's
working, and it is, so ignore the link and see it as I have it above.
Any advice? Code below.
