cakePHP and file uploads

[hartken]

When I create a form without a file upload field in cakephp, I am able to update the database. But when I add file upload fields, the database does not update. Here is my code:

controller:

PHP Code:

class CarsController extends AppController {

    var $name = 'Cars';
    var $helpers=array('Html','Form');
                                    
    
    //new car function for creating a new car record
    function register(){
        if(!empty($this->data)){
            if($this->Car->save($this->data,false)){
                $this->Session->setFlash('Car added');
            }
        }
    }
} 


model

PHP Code:

class Car extends AppModel {

    var $name = 'Car';
} 


view

PHP Code:

<?php echo $form->create('Car', array('action' => 'register', 'type' => 'file'));?>

<?php
    echo $form->input('stockno');
    echo $form->input('vin');
    echo $form->input('year');
    echo $form->input('make');
    echo $form->input('model');
    echo $form->input('type');
    echo $form->input('color');
    echo $form->input('engine');
    echo $form->input('transmission');
    echo $form->input('condition');
    echo $form->input('retailprice');
    echo $form->input('mileage');
    echo $form->input('warranty');
    echo $form->input('description');
    echo $form->file('front');
?>

<?php echo $form->end('Register');?>

Thanks.

I figured it out:

The file field returns as an array instead of a single value, causing save to fail. What I needed was a line of code setting $this->data['Car']['front'] to a single value, in this case, the tmp_name of the uploaded image.
