我在prestashop下创建了一个分页子类别，但是遇到了一个困难。当我来到最后一页时，我有2个空页面被添加更多。这是我在CategoryController中的函数：
/**
* Assigns subcategory templates variables
*/
protected function assignSubcategories()
{
// Get pagination parameter
$p = 1;
if ( isset( $_GET['p'] ) && ! empty( $_GET['p'] ) ) {
$p = (int) $_GET['p'];
}
if ($sub_categories = $this->category->getSubCategories($this->context->language->id)) {
$this->context->smarty->assign(array(
'subcategories_nb_total' => count($sub_categories),
'subcategories_with_pagination' => $this->category->getSubCategoriesWithPagination( $this->context->language->id, true, $p ),
'subcategories_nb_per_page' => ceil( count($sub_categories) / 15) ,
'subcategories_nb_half' => ceil(count($sub_categories) / 2)
));
}
}
我在第1页上的结果是正确的：
我的模板聪明：
{if isset($no_follow) AND $no_follow}
{assign var='no_follow_text' value='rel="nofollow"'}
{else}
{assign var='no_follow_text' value=''}
{/if}
{*{Fix page number, take subcategorys total number instead of products}*}
{assign var='pages_nb' value={$subcategories_nb_per_page}}
{if isset($p) AND $p}
{if isset($smarty.get.id_category) && $smarty.get.id_category && isset($category)}
{if !isset($current_url)}
{assign var='requestPage' value=$link->getPaginationLink('category', $category, false, false, true, false)}
{else}
{assign var='requestPage' value=$current_url}
{/if}
{assign var='requestNb' value=$link->getPaginationLink('category', $category, true, false, false, true)}
{/if}

这就是我在最后一页时所拥有的：
我检查我应该只有10页，其他2页是空的。
你知道这可能来自哪里吗？
谢谢。
