如何从输入表单Cakephp 3获取数据

Question

I am very new to this Cakephp framework, trying to follow and understand how to upload files using cakephp. I am using upload plugin provided by josediazgonzalez. In the view file, using formhelper i have:

<?= $this->Form->create($user, ['type' => 'file']) ?>
<fieldset>
    <legend><?= __('Add User') ?></legend>
    <?php
        echo $this->Form->control('name');
        echo $this->Form->control('username');
        echo $this->Form->control('password');
        echo $this->Form->control('role');
        echo $this->Form->input('photo', ['type' => 'file']); 
        echo $this->Form->control('dir');
    ?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>

I want to print again the value that i submitted in my controller, what should i write? Something like:

$this->request->data;

Answer 1

$this->request->data is an array of data passed to your scirpt. You can use it to get field that you are interested in with, eg:

$data = $this->request->data;
$someVariable = $data["name"];

Or, you can access any field directly, by using data() accessor:

$someVariable = $this->request->data("name");

From this point, you can do anything you want with this variable.

One more thing - as $this->request->data and $this->request->data() are currently in deprecated state and will be removed in next version, I suggest to use $this->request->getData() instead. Usage is similar:

$this->request->getData(); //will return array of data passed
$this->request->getData("field_name"); //access to specific field
