CakePHP 3 - $this->request->getData when reading POST arrays

0
votes

In CakePHP 3 I can access a POST variable such as start like this:

$this->request->getData('start')

If my POST value is in the form of an array - in plain PHP such as $_POST['order'][3]['column'] I can access it in Cake like this:

$this->request['data']['order'][3]['column']

Is this the correct (or only) way to do this, or should you also be able to use getData() to access it?

Use the OO way to access things. There are reasons why the interfaces exists to access data through them. See api.cakephp.org/3.4/class-Cake.Http.ServerRequest.html#_getData - floriank
Ok, but how could I access something that's in an array format as per my example (['order'][3]['column'])? I get how you do it for simple items where you just pass the name as a string to getData but that doesn't work for arrays, or so it seems? - Andy
As the API doc tells you Allows you to use Hash::get() compatible paths. so check api.cakephp.org/3.4/class-Cake.Utility.Hash.html#_get - floriank

// As array
$this->request->getData('order')[3]['column'];

// https://api.cakephp.org/3.4/class-Cake.Utility.Hash.html#_get
$this->request->getData('order.3.column');
