Question

我有一个php / wp脚本，理论上应该打印一个带有类别名称，描述及其所有产品的div。代码如下所示：

<?php

$args2 = array( 'taxonomy'  =>   'product_cat', 'parent' => 9 );
$sub_cats = get_categories( $args2 );

foreach( $sub_cats as $sub_category ) { ?>

    <div class="treatments-description col-md-9" id="<?php echo $sub_category->term_id;?>">

        <h2 class="section-heading">
            <span class="line-behind-text"><?php echo $sub_category->name;?></span>
        </h2>

        <p class="section-text">
            OPIS: <?php echo category_description(); ?> //this part does not work too, not sure why
        </p>

        <h3 class="section-heading"><p class="line-behind-text">Dostępne zabiegi</p></h3>

        <table class="treatments-table table products">

            <tr class="table-heading">
                <th class="name" id="<?php echo $sub_category->term_id;?>">Usługa</th>
                <th>Czas trwania</th>
                <th>Cena</th>
                <th></th>
            </tr> <?php

            $name = $sub_category->name;
            $args = array( 'post_type' => 'product', 
                           "product_cat" => $sub_category->term_id //PROBLEM HERE
                    );

             $loop = new WP_Query( $args );

             if ( $loop->have_posts() ) {

                 while ( $loop->have_posts() ) : $loop->the_post();

                     $product = new WC_Product(get_the_ID()); ?>

                     <tr>
                         <td class="name"><?php the_title(); ?><p class="small"><?php the_content(); ?></p></td>
                         <td><?php the_excerpt(); ?></td>
                         <td><?php echo $product->price; ?>zł</td>
                         <td><button class="button-product materialbutton">Rezerwuj</button> </td>
                    </tr> <?php

                 endwhile;
             } 
             else {

                 echo __( 'No products found' );
             } ?>

             <h1>THE END</h1> <?php
} //ALL UNCLOSED TAGS ARE GETTING CLOSED AFTERWARDS

现在理论上它应该显示这样的div：

类别a： 1A。类别说明 1B。类别表
类别b： 2A。类别说明 2B。类别表

但相反，结果如下：

因此，您看到它不仅没有正确布局页面（顺序是descrption1，description2，table1，table2，请注意<h1>THE END</h1>的位置），它似乎也没有正确匹配类别的产品。当Id放入数组

＆＃34; product_cat＆＃34; =＆GT; 14 //经过验证的类别ID，包含帖子

我在wp方面经验丰富，但对于woocommerce来说却相当新鲜。如果有人能帮助我解决这些问题，我们将非常高兴地感激不尽。

Answer 1

很难从你的图片中看出，但我差不多100％你没有正确关闭表格标签，你所描述的正是在这种情况下会发生的事情。

问题是你在一个迭代点（foreach）上打开一个表标签，然后在下一个迭代点添加2行，ok，到目前为止，在open table标签内添加一个h2标签，依此类推。

浏览器会尝试通过关闭标记为您修复这些标记但不会为您重新排列html，因此h标记在渲染视图中的表格上方可见。

见下文：只有有帖子才会打开表格。如果你想在没有帖子的情况下打开一个，你需要在宣布“找不到帖子”等之前关闭表格

<?php

$args2 = array( 'taxonomy'  =>   'product_cat', 'parent' => 9 );
$sub_cats = get_categories( $args2 );

foreach( $sub_cats as $sub_category ) { ?>

    <div class="treatments-description col-md-9" id="<?php echo $sub_category->term_id;?>">

        <h2 class="section-heading">
            <span class="line-behind-text"><?php echo $sub_category->name;?></span>
        </h2>

        <p class="section-text">
            OPIS: <?php echo category_description(); ?> //this part does not work too, not sure why
        </p>

        <h3 class="section-heading"><p class="line-behind-text">Dostepne zabiegi</p></h3>
        <?php

            $name = $sub_category->name;
            $args = array( 'post_type' => 'product', 
                           "product_cat" => $sub_category->term_id //PROBLEM HERE
                    );

             $loop = new WP_Query( $args );

             if ( $loop->have_posts() ) {
                //only include the table if we have posts???

                    echo '<table class="treatments-table table products">';

                    echo '<tr class="table-heading">
                        <th class="name" id="<?php echo $sub_category->term_id;?>">Usluga</th>
                        <th>Czas trwania</th>
                        <th>Cena</th>
                        <th></th>
                        </tr>';



                 while ( $loop->have_posts() ) : $loop->the_post();

                     $product = new WC_Product(get_the_ID()); ?>

                     <tr>
                         <td class="name"><?php the_title(); ?><p class="small"><?php the_content(); ?></p></td>
                         <td><?php the_excerpt(); ?></td>
                         <td><?php echo $product->price; ?>zl</td>
                         <td><button class="button-product materialbutton">Rezerwuj</button> </td>
                    </tr> <?php

                 endwhile;

                echo '</table>'; 


             } 
             else {

                 echo __( 'No products found' );
             } ?>

             <h1>THE END</h1> <?php
} //ALL UNCLOSED TAGS ARE GETTING CLOSED AFTERWARDS -- must close tags in the loop, otherwise multiple open tags!!

Answer 2

对于您的第一个问题，我非常确定您需要category_description();替换$sub_category->description;（在下面的代码中为$sub_cat->description;）
对于你的第二个问题，我无法测试，我不完全确定，但你需要更多的东西（ see in here ）......
您还需要使用</table>（接近结尾）和</div>（最后）关闭您的表格

<?php

    $args2 = array( 'taxonomy'  =>   'product_cat', 'parent' => 9 );
    $sub_cats = get_categories( $args2 );

    foreach( $sub_cats as $sub_cat ) { ?>
        $sub_cat_name = $sub_cat->name;
        $sub_cat_description = $sub_cat->description; // <= Here (1)
        $sub_cat_id = $sub_cat->term_id;

    <div class="treatments-description col-md-9" id="<?php echo $sub_category->term_id;?>">

        <h2 class="section-heading">
            <span class="line-behind-text"><?php echo $sub_cat_name; ?></span>
        </h2>

        <p class="section-text">
            OPIS: <?php echo $sub_cat_description; ?>
        </p>

        <h3 class="section-heading"><p class="line-behind-text">Dostępne zabiegi</p></h3>

        <table class="treatments-table table products">

            <tr class="table-heading">
                <th class="name" id="<?php echo $sub_cat_id; ?>">Usługa</th>
                <th>Czas trwania</th>
                <th>Cena</th>
                <th></th>
            </tr>
        <?php

            global $post; // Here (2)
            $terms = get_the_terms( $post->ID, 'product_cat' );
            foreach ($terms as $term) {
                $product_cat_id = $term->term_id;
                // $product_cat_name = $term->name;
                break;
            }
            $args = array( 
                'post_type' => 'product', 
                'product_cat' => $product_cat_id'
            );

            $loop = new WP_Query( $args );

            if ( $loop->have_posts() ) {

                while ( $loop->have_posts() ) : $loop->the_post();

                    $product = new WC_Product(get_the_ID()); ?>

            <tr>
                <td class="name"><?php the_title(); ?><p class="small"><?php the_content(); ?></p></td>
                <td><?php the_excerpt(); ?></td>
                <td><?php echo $product->price; ?>zł</td>
                <td><button class="button-product materialbutton">Rezerwuj</button> </td>
            </tr>
            <?php 
                endwhile; ?>
        </table>
        <?php 
            } 
            else {
                echo __( 'No products found' );
            } ?>

         <h1>THE END</h1> 
         <?php
         } 
         ?>
     </div>
