如何为WooCommerce插件创建“单一”类别小部件

时间：2013-01-24 作者：user26485

Woocommerce开箱即用提供了许多小部件，但是用于提供产品搜索的类别小部件将所有类别分组到一个小部件中。

我想要一个小部件用于一个类别，即“按意义购物”和另一个小部件“按字母购物”等。

我抓取了widget-product\\u类别的widget代码。来自woocommerce插件的php。。。我想我可以简单地修改我在woocommerce插件中创建的“大小”类别的代码。

然而，我很快发现这超出了我的范围。

由于我需要使用“shop by xxx”搜索创建4个不同的小部件，如果有任何帮助，我将不胜感激。下面是woo小部件的代码，它在一个小部件中提供了所有类别。

有没有办法为“尺寸”的单个类别退货重新编码？

var $woo_widget_description;
var $woo_widget_idbase;
var $woo_widget_name;

虽然有点晚了，但也许这对某人还是有帮助的。。。

如果您不介意硬编码父类别名称、slug和ID（例如“All”、“designer”、“38”），则可以创建下拉列表以跳转到指定ID的子类别：

<?php   
$terms = get_terms( \'product_cat\', \'child_of=38\' );
if ( $terms ) {
    print( \'<select name="product_cat" id="dropdown_product_cat">\' );
    print( \'<option value="designer" selected="selected">All</option>\' );
    foreach ( $terms as $term ) {
        printf( \'<option value="%s">%s</option>\', esc_attr( $term->slug ), esc_html( $term->name ) );
    }
    print( \'</select>\' );
} ?>
<script type="text/javascript">
/* <![CDATA[ */
        var product_cat_dropdown = document.getElementById("dropdown_product_cat");
        function onProductCatChange() {
                if ( product_cat_dropdown.options[product_cat_dropdown.selectedIndex].value !==\'\' ) {
                        location.href = "<?php echo home_url(); ?>/?product_cat="+product_cat_dropdown.options[product_cat_dropdown.selectedIndex].value;
                }
        }
        product_cat_dropdown.onchange = onProductCatChange;
/* ]]> */
</script>
