get the html of .ctp file in CAKEPHP - php

Question

I have deployed an app using cakephp. Now i have some data which i want to render on some logic. This data should be showed as a page including some inputs and other fields.
One thing is to do this in javascript side but it will not be a suitable option to make a whole html in javascript.
Other solution on which i am working is to pass the data to the .ctp file. Get the html and pas this to my content.
I am trying to do this as
$html = $this->render('myview');
$this->set('html', $view);
but it render the myview as a page not as html to be shown to my view.

Answer 1

Follow the code to achieve the same, (this code in your controller's method/action)
//Variables used in view
$data = $this->Admins->newEntity();
// create a builder
$builder = $this->viewBuilder();
// configure as needed
$builder->setLayout('default');
$builder->setTemplate('/Admins/login'); //Here you can use elements also
$builder->setHelpers(['Html']);
// create a view instance
$view = $builder->build(compact('data')); //Pass the variables to the view
// render to a variable
$output = $view->render();
//Print output
pr($output);
die;

From what I understood from your question and comments, you want to render something in a certain place of your view, but you want to put code for that component in separate .ctp file. CakePHP already has built in tools to achieve this - Elements and Cells.
Elements are reusable pieces of code, which resides in src/Template/Element directory. To create an element, simply create new .ctp file (eg. myelement.ctp) in this directory, and output it in your main view using:
<?= $this->element("myelement") ?>
Elements have access to variables passed to view from which are called, but if needed, one can also pass variables as second argument:
<?= $this->element("myelement", ["somevariable" => "somevalue"]) ?>
On the other hand, you have also Cells, which should be used in need to create an reusable component which depends on some logic which should be separated from controller code. Cell consists of two parts - a Cell class, which is equivalent for controller, and template file. It can be baked by:
bin/cake bake cell Sample
This command will create src/View/Cell/SampleCell.php and src/Template/Cell/Sample/display.ctp files. In first of them, a standard controller logic can be performed. In second, you can put HTML and access to passed variables. Cell can be rendered into a view by using:
<?= $this->cell("Sample") ?>
