Answer 1

I was getting same error, but I solved it. Here is my view and controller code related to image. The column name in my database table is "picture".
view file form input tag
<?php
echo $this->Form->file('picture', array('class'=>'form-control'));
?>
controller file :: PostController.php
public function addNewPost() {
$this->layout = false;
if ($this->request->is('post')) {
$data = $this->request->data; //echo '<pre>'; print_r($data); die;
if (!empty($data['Post']['picture']['name'])) {
$file = $data['Post']['picture'];
$ext = substr(strtolower(strrchr($file['name'], '.')), 1);
$arr_ext = array('jpg', 'jpeg', 'gif','png');
if (in_array($ext, $arr_ext)) {
move_uploaded_file($file['tmp_name'], WWW_ROOT . 'img/postimages/' . $file['name']);
$this->request->data['Post']['picture'] = $file['name'];
//echo '<pre>'; print_r($data); die;
}else{
$this->Session->setFlash(__('Please upload a valid image.'), 'default', array('id' => 'flashMessage', 'class' => 'alert alert-danger'), 'error');
}
}
$path = $data['Post']['picture']['name'];
if(isset($path)){
$data['Post']['picture'] ='postimages/' . $path;
}
$data['Post']['picture'] ='postimages/default.jpg';
//echo '<pre>'; print_r($data); die;
if ($this->Post->save($data)) {
$this->Session->setFlash(__('Congrats !!! Post Published to our blog. Thanks for posting.'), 'default', array('id' => 'flashMessage', 'class' => 'alert alert-success'), 'success');
return $this->redirect(array('controller' => 'dashboard', 'action' => 'addNewPost'));
} else {
$this->Session->setFlash(__('The Post could not be published. Please, try again.'), 'default', array('id' => 'flashMessage', 'class' => 'alert alert-danger'), 'error');
}
}
}
