cakephp passing variable to home.ctp

Question

With cakephp i'm making a simple slideshow.

In my PagesController i write the home action as follows:

public function home(){
    // slider
    $this->loadModel('CmsStoreSlider');
    $cmsStoreSlider = $this->CmsStoreSlider->find('all')->toArray();
    $this->set(compact('cmsStoreSlider'));
    $this->set('_serialize', ['cmsStoreSlider']);
}

... and in my Pages/home.ctp i try to call $cmsStoreSlider, but without luck.

<?php foreach ($cmsStoreSlider as $cmsStoreSlider): ?>
           <img src="<?= $cmsStoreSlider->image; ?>" alt="Imagem do slider">
<?php endforeach; ?>

The images are not displaying because cakephp says it invalid argument supllied for foreach. I made a var_dump and says $cmsStoreSlider is an undefined variable.

Any Solutions. i'm new to cake and maybe something is missing in my logic.

Ps. The Entity and table model are created.

Cakephp by default takes Pages controller's display actions as a home page. display function manages pages and subpages itself that is why you are getting error. Either you can change your default home page in your /config/routes.php

 $routes->connect('/', ['controller' => 'Pages', 'action' => 'home']);

OR

Remove code from display action

class PagesController {
    function display()
    {
        // default controller code here
        // your custom code here
    }
}

No. That is not the problem. If i delete the foreach and just make a simple var_dump($cmsStoreSlider) it says undefined variable. The problem is home function inside PagesController.php not passing $cmsStoreSlider to home.ctp. – André Castro Aug 28 '18 at 11:48
Are you using display function of PagesController for your website home page? – Sehdev Aug 28 '18 at 12:00
Yes. I am using display function and below that one home() function. – André Castro Aug 28 '18 at 12:06

You have to overwrite display function to pass the variable. Please following any one solution from this link https://stackoverflow.com/questions/51838952/how-to-use-this-autorender-false-in-cakephp-3-6-10/51840289#51840289 – Sehdev Aug 28 '18 at 12:09
Yes. That's the answer. I overwrite display function and now it works. Image is displaying fine. Thank you @Sehdev. – André Castro Aug 28 '18 at 12:13
