CakePHP: Error message not showing Validate Fields

Question

I am new to CakePHP. I have two problem with the view.

• There is line break between text field name and text field area. I have tried to pass 'div' => false but that didn't work. How can I remove line break and display both on same line?

• I have added validation rule to this textfield but when I click save Error message doesn't show up. Do I need to do something else beside adding validates in my model?

Here is my view input.ctp

echo $this->Form->input('fileId', array(
    'type'=>'text', 
    'style' => 'width: 200px; height: 15px'
));
echo $this->Form->end('Save Post');

Here is my model:

var $validate = array(
    'fileId' => 'notEmpty',
    'message' => 'Should not be empty'
    );

Controller:

if ($this->request->is('post')) {
    $data = $this->request->data;
    if ($data) {
        // saving the data
    }
}

Answer 1

If you are not using save then you need to manually validate the data using validates. In such case you also need to set the data. For e.g. in your controller

   $this->ModelName->set($data);
   $this->Modelname->validates();

Answer 2

For validate your data, you should have something like this:

public $validate = array(
    'fileId' => array(
        'rule' => 'notEmpty',
        'message' => 'Should not be empty'
    )
);

And your Controller:

if ($this->request->is('post')) {
    if ($this->Model->save($this->request->data)) {
        // saved
    }
}

If you can not save, the error will be shown near the corresponding field. Or you can customize your error using $this->Model->validationErrors array.

For the line break question, make sure that 200px does the automatic line break because of where these elements are positioned.
