Hi, I had the same problem as you. I was not able to use javascript to
redirect (using location.href), got error message about no access to
the directory. The history.back() doesn't work too well for me because
user could be trying to save but encounter validation error and after
several times, decided to cancel the operation, but the history.back()
will return to just one step behind, and not to the main list.
Here is how I solve it, basically make use of the 'name' tag and check
for the button pressed in controller function to redirect accordingly.
This should also solve the cross-browser issue.
In the view, I added the following buttons.
=====
..... Start of form and elements code .....
<div class="button">
<?php echo $form->submit('Save Job Type', array('div'=>false,
'name'=>'submit')); ?>
<?php echo $form->submit('Cancel', array('div'=>false,
'name'=>'cancel')); ?>
</div>
..... End of form code .....
=====
At the beginning of my controller add function (for example), I do
this first.
if (array_key_exists('cancel', $this->params['form'])) {
$this->flash('Cancelled adding new job type.','/job_types');
}
... Rest of the data validation and saving logic ...
