Accessing Data in a Controller rather than view

[ryanam1]

Hi,

How can I access data within a controller?

Lets say I have the following find() method in my controller

$mydata=$this->User->find('all', array('conditions'=>'new;),
'fields'=>array('name'))

Let's say I wanted to do some sort of proccessing to that data before
outputting to a view How would I do that?

I see examples of how to output that data in the view but I see none
about accessing the data from within the controller.

I figure I should do a loop but how should I write $mydata?

Should it be like this:  $mydata['User']['name']  ?  That seems to
work in the view but I get a "Undefined Index" error when I write it
that  way from within the controller.

I don't have the issue when a method returns one record such as field
() because it is not returning an array

I hope I'm not confusing anyone :(

Re: Error message for the extension validation rule will not display

[ryanam1]

Thanks guys...

I didn't see that missing closing parentheses,

Unfortunately the error message still did not show but I figured it
out.

In my view I added the following line:
echo $form->error('imagename');

Error message for the extension validation rule will not display

[ryanam1]

Hi,

I am new to CakePHP and I am having trouble getting the extension
error message to display. The error message for the email rule
displays fine when someone enters an improperly formatted email and I
tried other examples of Cake's built in validation, they all seem to
work fine except for the extension validation.  Can someone please
tell me what I am doing wrong.

Here are the validation rules in my model:
  var $validate = array(
'imageupload' => array(
'rule' => array('extension', array('gif', 'jpeg', 'png',
'jpg'),
'message' => 'Please supply a valid image.'
)
)
,
'email'=>array(
'rule'=>'email',
'message'=>'Please enter a proper email'
)
);


Here is the snippet code in the Controller:
   function add(){
if (!empty($this->data)) {

if($this->Student->save($this->data)){

$this->flash('Success','/add');
}
}
}

Finally the snippet code in my view:
create('Student',array('type' => 'file'));
echo $form->input('email');
echo $form->file('imageupload');
echo $form->end('Add');
?>

Again, the display message for the email displays correctly so I know
that the validation is working at least somewhat.  The validation for
the file upload seems to operate correctly. If I try to upload a file
with a .DOC extension the "save" fails except that it does not display
the error message at all.

Please help what am I doing wrong?
