Change the limit from CakePHP 3 Paginator by click in link inside an <option>

Question

I'm using the CakePHP 3.0 to paginate some content, but I can't find a way to change the limit (user on browser choose the limit of content displayed on screen) using Paginator built-in method (like sort built-in), to do this I use javascript to change limit in URL.

Qustion: Exist any way to do this in cakephp style ?

Controller action that uses paginate

public $helpers = [
    'Paginator' => ['templates' => 'paginator-templates']
];

public function search()
{
    if($this->request->is('get'))
    {
        $search = $this->request->query['search'];
        @$limit = $this->request->query['limit'] ?: 3;

        $this->paginate = [
            'conditions' => ['product_name LIKE' => '%' . $search . '%'],
            'limit' => $limit,
            'contain' => ['Medias' => function($q){
                return $q->select(['path', 'product_id'])
                    ->where(['media_type_id' => 3]);
            }]
        ];

        $products = $this->paginate($this->Products);
     }
}

Select with pagination limits:

<select name="products-view" class="form-control products-view inline-pagination-menu" id="products-view">
    <option value="3">3</option>
    <option value="6">6</option>
    <option value="9">9</option>
</select>

Javascript responsible to change limit in URL

$('#products-view').change(function(){
    changeLimitPagination(this);
});

function changeLimitPagination(option){
    location.search = $.query.set('limit', option.value).toString();
}

I will admit that I am not really familiar with CakePHP so I am not sure how to answer "Exist any way to do this in cakephp style?" - did you ever find an answer for that?

I am intrigued by the following line:

@$limit = $this->request->query['limit'] ?: 3;

shouldn't the error control operator be prepended before the right hand side of the assignment operator?

$limit = @$this->request->query['limit'] ?: 3;

I haven't tried the error control operator on that side... maybe it still works the same...

Looking at the JavaScript code, it appears that the option parameter actually corresponds to the select list

$('#products-view').change(function(){
    changeLimitPagination(this);
});

function changeLimitPagination(option){
    console.log(' option tagName: ', option.tagName, ' id: ', option.id);
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="products-view" class="form-control products-view inline-pagination-menu" id="products-view">
    <option value="3">3</option>
    <option value="6">6</option>
    <option value="9">9</option>
</select>

So a better name would be something like productsList or limitList. Also, that doesn't really need to be a parameter - it could be stored in a variable outside the function. While you might still need to use jQuery for other code, regular JavaScript code could be used to select the element by id attribute with document.getElementById() and then add the change handler via EventTarget.addEventHandler(). That way, changeLimitPagination could simply be added as the callback to the change handler instead of an extra anonymous function that has the sole purpose of calling changeLimitPagination.

var productsView = document.getElementById('products-view');
productsView.addEventListener('change', changeLimitPagination);

function changeLimitPagination(){
    console.log('changeLimitPagintation() - value: ', productsView.value);
    //location.search = $.query.set('limit', option.value).toString();
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="products-view" class="form-control products-view inline-pagination-menu" id="products-view">
    <option value="3">3</option>
    <option value="6">6</option>
    <option value="9">9</option>
</select>
