我无法在主菜单模块(ps_mainmenu)中设置显示类别拇指。我在Prestashop 1.6中管理它,但模块已经改变。
在Prestashop 1.7管理员中,您可以添加类别缩略图。
这是一张图片,展示了我尝试实现的目标:Category thumb above category labels in main menu
致以最诚挚的问候,

您需要修改菜单的模板文件,最好在主题themes/your_theme/modules/ps_mainmenu/ps_mainmenu.tpl
中进行修改,然后添加相似的代码部分
{if $node.type == 'category'}
{if isset($node.image_urls) && $node.image_urls}
{foreach from=$node.image_urls item='thumb'}
<img src="{$thumb}" alt="" />
{/foreach}
{/if}
{/if}
在{foreach from=$nodes item=node}
内
就我而言,它看起来像这样
{assign var=_counter value=0}
{function name="menu" nodes=[] depth=0 parent=null}
{if $nodes|count}
<ul class="top-menu" {if $depth == 0}id="top-menu"{/if} data-depth="{$depth}">
{foreach from=$nodes item=node}
<li class="{$node.type}{if $node.current} current {/if}" id="{$node.page_identifier}">
{if $node.type == 'category'}
{if isset($node.image_urls) && $node.image_urls}
{foreach from=$node.image_urls item='thumb'}
<img src="{$thumb}" alt="" />
{/foreach}
{/if}
{/if}
{assign var=_counter value=$_counter+1}
<a
class="{if $depth >= 0}dropdown-item{/if}{if $depth === 1} dropdown-submenu{/if}"
href="{$node.url}" data-depth="{$depth}"
{if $node.open_in_new_window} target="_blank" {/if}
>
{if $node.children|count}
{* Cannot use page identifier as we can have the same page several times *}
{assign var=_expand_id value=10|mt_rand:100000}
<span class="float-xs-right hidden-md-up">
<span data-target="#top_sub_menu_{$_expand_id}" data-toggle="collapse" class="navbar-toggler collapse-icons">
<i class="material-icons add"></i>
<i class="material-icons remove"></i>
</span>
</span>
{/if}
{$node.label}
</a>
{if $node.children|count}
<div {if $depth === 0} class="popover sub-menu js-sub-menu collapse"{else} class="collapse"{/if} id="top_sub_menu_{$_expand_id}">
{menu nodes=$node.children depth=$node.depth parent=$node}
</div>
{/if}
</li>
{/foreach}
</ul>
{/if}
{/function}
<div class="menu js-top-menu position-static hidden-sm-down" id="_desktop_top_menu">
{menu nodes=$menu.children}
<div class="clearfix"></div>
</div>
它起作用但对我来说不是绝对可预测的。因为它仅将图像添加到具有子类别的类别。因此,如果可以,则可以将其置于此状态,但如果没有,并且您希望显示所有类别的图像,则需要修改模块控制器文件。
转到核心模块文件夹modules/ps_mainmenu/ps_mainmenu.php
内的模块并修改方法generateCategoriesMenu
。删除代码
$files = scandir(_PS_CAT_IMG_DIR_);
if (count(preg_grep('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $files)) > 0) {
foreach ($files as $file) {
if (preg_match('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $file) === 1) {
$image_url = $this->context->link->getMediaLink(_THEME_CAT_DIR_.$file);
$node['image_urls'][] = $image_url;
}
}
}
来自条件if (isset($category['children']) && !empty($category['children']))
的并把它准确地放在条件之前。

我回到我的项目并升级了Prestashop,然后我的菜单消失了,我忘记了这个答案。再次感谢Alexander Grosul。
这里有什么方法可以覆盖PS_MainMenu并使类别拇指显示出来,即使类别没有子代也是如此。
新文件:
class Ps_MainMenuOverride extends Ps_MainMenu {
protected function generateCategoriesMenu($categories, $is_children = 0)
{
$nodes = [];
foreach ($categories as $key => $category) {
$node = $this->makeNode([]);
if ($category['level_depth'] > 1) {
$cat = new Category($category['id_category']);
$link = $cat->getLink();
} else {
$link = $this->context->link->getPageLink('index');
}
$node['url'] = $link;
$node['type'] = 'category';
$node['page_identifier'] = 'category-' . $category['id_category'];
/* Whenever a category is not active we shouldnt display it to customer */
if ((bool)$category['active'] === false) {
continue;
}
$current = $this->page_name == 'category' && (int)Tools::getValue('id_category') == (int)$category['id_category'];
$node['current'] = $current;
$node['label'] = $category['name'];
$node['image_urls'] = [];
$files = scandir(_PS_CAT_IMG_DIR_);
if (count(preg_grep('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $files)) > 0) {
foreach ($files as $file) {
if (preg_match('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $file) === 1) {
$image_url = $this->context->link->getMediaLink(_THEME_CAT_DIR_.$file);
$node['image_urls'][] = $image_url;
}
}
}
if (isset($category['children']) && !empty($category['children'])) {
$node['children'] = $this->generateCategoriesMenu($category['children'], 1);
}
$nodes[] = $node;
}
return $nodes;
}
}
确保删除缓存或强制编译
这应该可以解决问题,并且即使在更新后也可以保留。
