获取Woomerce产品类别图像URL

custom-taxonomy woocommerce image wordpress php

Kenshinh · 技术社区 · 6 年前

我使用了下面的代码来获取Woomerce产品类别的缩略图URL,但它只输出 <img> 标记为 src="unknown" 是的。

$cat_slug = t-shirts;
$thumbnail_id = get_woocommerce_term_meta( $cat_slug, 'thumbnail_id', true );
$image = wp_get_attachment_url( $thumbnail_id );
echo '<img src="'.$image.'" alt="" width="50" height="50" />';

什么是让它发挥作用的最佳方法?

编辑

在第二次调用jean类别的缩略图时,它只输出 <img src(unknown) alt="" width="50" height="50" /> 是的。

<div class="list-item">
    <div class="item-img">

        <?php

        $term_slug    = 't-shirts';
        $taxonomy     = "product_cat";
        $term_id      = get_term_by( 'slug', $term_slug, $taxonomy )->term_id;
        $thumbnail_id = get_woocommerce_term_meta( $term_id, 'thumbnail_id', true );
        $image        = wp_get_attachment_url( $thumbnail_id );

        echo '<img src="'.$image.'" alt="" width="50" height="50" />';

        ?>

</div>

<a href="#">
    <div class="item-name">
        <?php if( $term = get_term_by('slug', 't-shirts', 'product_cat') ) echo $term->name;?>
    </div>
</a>

</div>

<div class="list-item">
    <div class="item-img">

        <?php

        $term_slug    = 'jeans';
        $taxonomy     = "product_cat";
        $term_id      = get_term_by( 'slug', $term_slug, $taxonomy )->term_id;
        $thumbnail_id = get_woocommerce_term_meta( $term_id, 'thumbnail_id', true );
        $image        = wp_get_attachment_url( $thumbnail_id );

        echo '<img src="'.$image.'" alt="" width="50" height="50" />';

        ?>

</div>

<a href="#">
    <div class="item-name">
    <?php if( $term = get_term_by('slug', 'jeans', 'product_cat') ) echo $term->name;?>
    </div>
</a>

</div>

功能 get_woocommerce_term_meta() 需要术语id而不是术语slug。所以你可以用 get_term_by() wordpress函数从术语slug获取术语id。

所以你的密码是:

$term_slug    = 't-shirts';
$taxonomy     = 'product_cat';
$term_id      = get_term_by( 'slug', $term_slug, $taxonomy )->term_id;
$thumbnail_id = get_woocommerce_term_meta( $term_id, 'thumbnail_id', true );
$image        = wp_get_attachment_url( $thumbnail_id );

// Output
echo '<img src="'.$image.'" alt="" width="50" height="50" />';

测试和工作

添加版本3 (与您的评论相关)

我使用foreach循环进行了一些其他更改,优化了代码并允许您 添加任意数量的产品类别段塞 .

我还添加了术语链接,并做了一些小改动。

<?php
$term_slugs   = array('jeans', 't-shirts');
$taxonomy     = "product_cat";

// Loop though the term slugs array
foreach ( $term_slugs as $term_slug ):
    $term        = get_term_by( 'slug', $term_slug, $taxonomy );
    if( $term ):
        $term_link   = get_term_link( $term, $taxonomy );

        $thumb_id    = get_woocommerce_term_meta( $term->term_id, 'thumbnail_id', true );
        $img_src     = wp_get_attachment_url( $thumb_id );
        ?>
        <div class="list-item">
            <div class="item-image">
                <img src="<?php echo $img_src; ?>" alt="" width="50" height="50" />
            </div>
            <div class="item-name">
                <a href="<?php echo $term_link; ?>"><?php echo $term->name; ?></a>
            </div>
        </div>
    <?php endif;
endforeach; ?>

get_woocommerce_term_meta 有 term_id 作为第一个参数。参考 Here

像这样的代码

$termId = 1;
$thumbnail_id = get_woocommerce_term_meta( $termId, 'thumbnail_id', true );

或者

要从slug name获取缩略图,必须使用 get_term_by 是的。你可以参考 here

$termName = 't-shirts';
$category = get_term_by('name', $termName, 'product_cat');

$termId = $category->term_id;
$thumbnail_id = get_woocommerce_term_meta( $termId, 'thumbnail_id', true );
$image = wp_get_attachment_url( $thumbnail_id );
echo '<img src="'.$image.'" alt="" width="50" height="50" />';
