Question

我正在使用OpenCart，我正在尝试渲染meta_description（用于识别漫画发布者）并使用它来制作包含子类别的下拉列表，或者给出幻觉。这是我的代码，它是当前OpenCart代码的采用版本。 ['class']是我如何抓住子类别meta_description。

基本上，第二个for语句不起作用 - 它只执行第一个。我很感激对此的任何支持。

    <div class="menu">
     <div id="top"></div>
    <span>          
        <ul id="nav">
            <?php foreach ($categories as $category) { ?>
            <li><a href="#"><?php echo $category['name']; ?></a>
                <?php if ($category['children']) { ?> 
                <div class="subs">
                    <div>
                        <?php for ($i = 0; $i < count($category['children']);) { ?>
                        <ul>
                            <?php $j = $i + ceil(count($category['children']) / $category['column']); ?>                                
                            <h3>DC Comics</h3>

Answer 1

使用different variables中的loops，code $i main loop使用incremented，inner loops使用foreach loop <?php foreach ($categories as $category) { ?> <li><a href="#"><?php echo $category['name']; ?></a> <?php if (is_array($category['children']) and isset($category['children'])) { ?> <div class="subs"> <div> <ul> <?php $li1='<li><h3>DC Comics</h3><ul>'; $li2='<li><h3>Marvel</h3><ul>'; foreach($category['children'] as $child) { if($child['class'] == "DC Comics") { $li1.='<li><a href="'.$child['href'].'">'.$child['name'].'</a></li>'; } if($child['class'] == "Marvel") { $li2.='<li><a href="'.$child['href'].'">'.$child['name'].'</a></li>'; } } $li1.='</ul></li>'; $li2.='</ul></li>'; echo $li1; echo $li2; ?> </ul> </div> </div> <?php } ?> </li> <?php } ?>使用{{1}}之类的，

{{1}}

对于循环，运行一次？
