Prestashop 1.7产品每页下拉列表类别

I am looking through Prestashop 1.7 and i want to overide the controller responsible for Products Listing ( aka Category Archive ). I am using the official Prestashop starter theme and i want to override the controller in order to get some more data to the sort-order.tpl

<div class="products-sort-order">
  <span>{if isset($listing.sort_selected)}{$listing.sort_selected}{else}{l s='Sort by:' d='Shop.Theme.Global'}{/if}</span>
  {foreach from=$sort_orders item=sort_order}
    <a
      class="{['current' => $sort_order.current, 'js-search-link' => true]|classnames}"
      href="{$sort_order.url}"
      rel="nofollow"
    >
      {$sort_order.label}
    </a>
  {/foreach}
</div>

In the above snippet there is a sort_order variable , part of a $listing variable comming from products-top.tpl

<div id="js-product-list-top" class="products-selection">
  {if $listing.pagination.total_items|count > 1}
    <p>{l s='There are %product_count% products.' d='Shop.Theme.Catalog' sprintf=['%product_count%' => $listing.pagination.total_items|count]}</p>
  {elseif $listing.pagination.total_items > 0}
    <p>{l s='There is 1 product.' d='Shop.Theme.Catalog'}</p>
  {/if}

  {block name='sort_by'}
    {include file='catalog/_partials/sort-orders.tpl' sort_orders=$listing.sort_orders}
  {/block}

  {block name='pagination_summary'}
    {l s='Showing %from%-%to% of %total% item(s)' d='Shop.Theme.Catalog' sprintf=[
    '%from%' => $listing.pagination.items_shown_from ,
    '%to%' => $listing.pagination.items_shown_to,
    '%total%' => $listing.pagination.total_items
    ]}
  {/block}
</div>

My goal is to override the responsible controller in order to generate some links to alter the resultsPerPage just like the $sort_order changes the listing order passing some parameters to the url. The problem is that althought i've search nearly all controllers , i did not find the one passing those data to the tpl. Due to the lack of proper documentation i am asking for a bit of "where-is-that" information from a more experienced dev Thanks in advance

    First, create an override for classes/controller/ProductListingFrontController.php

    and change line 279:

    $resultsPerPage <= 0 || $resultsPerPage > 36
    

    to (for example..)

    $resultsPerPage <= 0 || $resultsPerPage > 100
    

    100 in this example is the max number of items you want per page. You can also choose more or less, depending what you want. Now let's alter your .tpl

    In your theme, go to themes/yourtheme/templates/catalog/_partials/sort-orders.tpl

    On the top of the page (right underneath the licence) add this to assign the variables:

    {if !empty($smarty.get.order)}
            {capture assign='ordering'}order={$smarty.get.order}&amp;{/capture}
        {else}
            {assign var='ordering' value=''}
        {/if}
    
        {if !empty($smarty.get.resultsPerPage)}
            {assign var='results_per_page' value=$smarty.get.resultsPerPage}
        {else}
            {assign var='results_per_page' value=25}
        {/if}
    

    And now, right underneath, add this code:

    <div class="col-md-3">
      <label style="float:left;margin-right: 15px" class="form-control-label hidden-sm-down sort-label">{l s='Products per page:'}</label>
      <div style="float:left;" class="sort-select dropdown js-dropdown">
        <a class="custom-select select-title" rel="nofollow" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            {$results_per_page}
        </a>
        <div class="dropdown-menu">
          <a rel="nofollow" href="?{$ordering}resultsPerPage=25" class="dropdown-item js-search-link">
                25
            </a>
          <a rel="nofollow" href="?{$ordering}resultsPerPage=50" class="dropdown-item js-search-link">
                50
            </a>
          <a rel="nofollow" href="?{$ordering}resultsPerPage=75" class="dropdown-item js-search-link">
                75
            </a>
          <a rel="nofollow" href="?{$ordering}resultsPerPage=100" class="dropdown-item js-search-link">
                100
            </a>
        </div>
      </div>
    </div>
    

    You might need to change the layout (or the number of items, or the max results per page...) but you'll be good to go :)

    If you're going to change the number of items (in the dropdown) for example, just change:

    <a rel="nofollow" href="?{$ordering}resultsPerPage=25"
    

    to

    <a rel="nofollow" href="?{$ordering}resultsPerPage=40"
    

    To adjust the amount of products per page.
