Get and post in cakephp - php

Question

In Codeigniter I do this
$p=$this->input->post();
to get all objects posted but I don't know if there is something similar in cakephp to get all posted variables from a form ? I am writing a function to get posted password and save it into database in place of the old password recorded there.
I use native php to get 'posted' variables from a form, (I am not familiar with cakephp form usage) that is why, so instead of using $_POST['sssss'] what should I do now ?
Thank you for any help.

Answer 1

$value = $this->request->data('key');
Please for further reference, read the manual. It's so much easier and better for yourself to figure it out by yourself.

Answer 2

for the GET method
$this->request->query['category-name'];
and POST method
$this->request->data

Answer 3

You can check if posted a form by using
if (!empty($this->data)) {
print_r($this->data);
}

Answer 4

The Post data must be in data to show up in $this->request->data.
Example:
// input field
<input type="text" name="data[foo]" value="bar" />
// in your controller
debug($this->request->data);

Answer 5

To check if posted a form, please use:
if ($this->request->is('post')) {
pr($this->request->data);
}

Answer 6

If you want to get a specific field of the table can move so:
if($this->data["Objetorastreavel"]["id"]){
}
It checks only the ID Objetorestraeval if you want to pick only one field and not post the whole page.

Answer 7

You should able to access form post data with:
For CakePHP 2.x
if ($this->request->is('post')) {
pr($this->request->data);
}
For CakePHP 3.4.x
if ($this->request->is('post')) {
pr($this->request->getData());
}
