difference between $this-data and $this-set('data')
hi,
Can someone can tell me the difference between using $this-
set('data', array()) and $this-data in controller.
I am especially getting confused about this in relation to form. In
general to send data to view, we have to set the variable using $this-
set(data, array). But to set the form, we need to use $this-data
bingo.

Re: difference between $this-data and $this-set('data')
$this-set('yourvar', $somedata) will create a variable called
$yourvar in the view, with the passed data. $this-data is model data
that is from/for a form - all of the FormHelper functions look at
$this-data to prepopulate from, and all the data they submit comes
into your controller under $this-data.
So basically, you should not have $this-set( 'data', $something ),
because it becomes confusing having a $data variable and $this-data,
which are quite different in scope and usage.

Re: difference between $this-data and $this-set('data')
And in case you weren't aware - you can access $this-data directly in
both the view and the controller. So in your view you can have
something like:
h2Change password for `?php echo $this-data['User']['name']; ? /
h2
?php echo $form-input('User.password'); ?
and both parts here will access the same user object, from $this-
data['User'] in the controller.

Re: difference between $this-data and $this-set('data')
$this-set('data', array()) will make $data available in your view.
That means, you can write something like echo $data; in your view
file.
On the other hand, $this-data contains submitted data from your form.

Re: difference between $this-data and $this-set('data')
$this-data is also available in your view in Cake 1.2. It is a copy of $this-data that is in the controller. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.
