Cakephp 3种形式，插入到FOREIGN KEY中

Question

Here is are my cods:

<?= $this->Form->create('Posts', array('url' => array('controller' => 'MyController', 'action' => 'index')));?>
                        <?= $this->Form->input('title', array('type'=>'title','class'=>'form-control mr-sm-2'));?>
                        <?= $this->Form->textarea('text', array('type'=>'text','rows' => '3','class'=>'form-control'));?>
                        <?= $this->Form->submit('Posten', array('class'=>'btn btn-outline-success my-2 my-sm-0','style'=>'float:right'));?>
                    <?= $this->Form->end();?>

And here is my Controller:

 $post = $this->Posts->newEntity();
    if ($this->request->is('post')) {
        $post = $this->Posts->patchEntity($post, $this->request->getData());
        debug($post);
        if ($this->Posts->save($post)) {

        $this->Flash->success(__('You have posted something.'));
        }


        return $this->redirect(['action' => 'index']);
    }else {
        $this->Flash->error(__('Error, plase check your'));
    }

The Problem is the Problem:

INSERT INTO posts (title, text) VALUES (:c0, :c1);

But i need :

INSERT INTO posts (title, text,user_id,picture_id) VALUES (a,b,$user_id,$picture_id);

The Preoblem is that i need to insert it in Controller not in view. Can someone help me?

Answer 1

Assuming that $user_id and $picture_id are variables that have been declared in your controller function, and have been properly checked for security if they are coming from user input (eg if they're in the URL, you've confirmed that they are okay and not just trusted them because the URLs that you give people links to are always valid), then the following should work:

$post = $this->Posts->patchEntity($post,
    array_merge($this->request->getData(), compact('user_id', 'picture_id'))
);
