php – WooCommerce品牌分类术语列表在下拉选择器中

2023年12月29日 149次阅读

我不想使用任何插件来完成这项任务,因为我最近经历了类似的项目破坏网站的冲突.所以我希望从基础知识中创建这个功能.

我需要在产品类别页面上的下拉列表中按品牌选择产品.下拉列表将显示所有品牌.当您选择一个时,该网站仅显示分配给该品牌的产品.我们不需要使用允许按新颖性,价格,受欢迎程度等查看的内置下拉菜单.

使用WooCommerce’品牌’分类法,我已经建立了自己的品牌,并为每个产品分配了一个品牌.

我可以使用以下代码查看所有品牌及其属性的数组：

$brands = get_terms('brand');
print_r($brands);

其中输出如下：

Array (

[0] => WP_Term Object ( [term_id] => 978 [name] => Imari Sometsuke [slug] => imari-sometsuke [term_group] => 0 [term_taxonomy_id] => 978 [taxonomy] => brand [description] => [parent] => 0 [count] => 1 [filter] => raw )

[1] => WP_Term Object ( [term_id] => 982 [name] => Kutani [slug] => kutani [term_group] => 0 [term_taxonomy_id] => 982 [taxonomy] => brand [description] => [parent] => 0 [count] => 2 [filter] => raw )

[2] => WP_Term Object ( [term_id] => 977 [name] => Kutani Shoza [slug] => kutani-shoza [term_group] => 0 [term_taxonomy_id] => 977 [taxonomy] => brand [description] => [parent] => 0 [count] => 4 [filter] => raw )

[3] => WP_Term Object ( [term_id] => 979 [name] => Kutani Tokkuri [slug] => kutani-tokkuri [term_group] => 0 [term_taxonomy_id] => 979 [taxonomy] => brand [description] => [parent] => 0 [count] => 2 [filter] => raw )

[5] => WP_Term Object ( [term_id] => 985 [name] => Nishikawa Sukenobu [slug] => nishikawa-sukenobu [term_group] => 0 [term_taxonomy_id] => 985 [taxonomy] => brand [description] => [parent] => 0 [count] => 1 [filter] => raw )

[6] => WP_Term Object ( [term_id] => 984 [name] => Shinsui Ito [slug] => shinsui-ito [term_group] => 0 [term_taxonomy_id] => 984 [taxonomy] => brand [description] => [parent] => 0 [count] => 2 [filter] => raw )

[7] => WP_Term Object ( [term_id] => 976 [name] => Takeji Asano [slug] => takeji-asano [term_group] => 0 [term_taxonomy_id] => 976 [taxonomy] => brand [description] => [parent] => 0 [count] => 2 [filter] => raw )

[8] => WP_Term Object ( [term_id] => 980 [name] => Toshusai Sharaku [slug] => toshusai-sharaku [term_group] => 0 [term_taxonomy_id] => 980 [taxonomy] => brand [description] => [parent] => 0 [count] => 3 [filter] => raw )

)

如何构建下拉列表(选择)列表来创建它？
我想它会有类似的框架,我已经开始了：

<?php
$brands = get_terms('brand');
//print_r($brands);
?>

<select name="orderby" class="orderby">
    <?php foreach ( $brands as ??? ) : ?>
        <option value="<?php echo esc_attr( $??? ); ?>" <?php selected( $orderby, $??? ); ?>><?php echo esc_html( $??? ); ?></option>
    <?php endforeach; ?>
</select>

最佳答案 正如您所看到的那样,它是一个术语对象数组(WP_Term对象),您必须在循环中使用该术语的每个属性的对象语法,这样：

<?php

    $brands = get_terms( 'brand', array(
        'orderby'  => 'name'  // orderby arguments ('name', 'slug','term_group', 'term_id', 'id', 'description')
    ) );
    //print_r($brands);

?>
<select name="orderby" class="orderby">
    <?php
        foreach ( $brands as $key => $brand ) :
            $brand_id = $brand->term_id;
            $brand_name = $brand->name;
            $brand_slug = $brand->slug;
            $brand_term_group = $brand->term_group;
            $brand_term_taxonomy = $brand->term_taxonomy_id;
            $brand_taxonomy = $brand->taxonomy;
            $brand_description = $brand->description;
            $brand_parent = $brand->parent;
            $brand_count = $brand->count;
            $brand_filter = $brand->filter;

            $number = $key+1;
            $option = 'option-' . $number;
    ?>
        <option value="<?php echo $option; ?>"><?php echo $brand->name; ?></option>
    <?php endforeach; ?>
</select>

此代码经过测试和运行
