由于我的商店有很多子类别,我试图从我的小部件中排除所有类别,其中只有1个产品。
现在我发现以下代码可以通过ID排除猫,但在这种情况下这样做太费时间了。有关如何编辑此代码以通过帖子计数排除的任何建议吗?
add_filter( 'woocommerce_product_categories_widget_args', 'wdm_edit_product_cat_widget_args' ); function wdm_edit_product_cat_widget_args( $cat_args ) {
$cat_args['exclude'] = array('10387');
return $cat_args;}
答案 0 :(得分:1)
我想到的一个有趣的方法是使用您定制的Walker列出类别。你有一些选择,包括:
您可以检查某个商品是否包含1个商品,然后您可以添加商品 条件标签并防止它出现。
您可以在li类中添加该项目中的产品数量 使用css隐藏您的某些类(.cat-count-1)中的项目 情况下。
我个人喜欢第二种方式,因为它可以让你以后随意做任何事情。
1-在主题的functions.php
文件中添加以下代码:
add_filter('woocommerce_product_categories_widget_args', 'use_different_walker_with_counts');
function use_different_walker_with_counts($args){
include_once 'wc_walker_with_counter_class.php';
$args['walker'] = new WC_Product_Cat_List_Counter_Walker;
return $args;
}
这告诉wordpress使用另一个定制的助行器。
2-使用以下行在主题文件夹名称wc_walker_with_counter_class.php
中添加新文件:
<?php
class WC_Product_Cat_List_Counter_Walker extends Walker {
/**
* What the class handles.
*
* @var string
*/
public $tree_type = 'product_cat';
/**
* DB fields to use.
*
* @var array
*/
public $db_fields = array(
'parent' => 'parent',
'id' => 'term_id',
'slug' => 'slug'
);
/**

*
* @see Walker::start_lvl()
* @since 2.1.0
*
* @param string $output Passed by reference. Used to append additional content.

* @param array $args Will only append content if style argument value is 'list'.
*/
public function start_lvl( &$output, $depth = 0, $args = array() ) {
if ( 'list' != $args['style'] )
return;
$indent = str_repeat("\t", $depth);
$output .= "$indent<ul class='children'>\n";
}
/**
* Ends the list of after the elements are added.
*
* @see Walker::end_lvl()
* @since 2.1.0
*
* @param string $output Passed by reference. Used to append additional content.
* @param int $depth Depth of category. Used for tab indentation.
* @param array $args Will only append content if style argument value is 'list'.
*/
public function end_lvl( &$output, $depth = 0, $args = array() ) {
if ( 'list' != $args['style'] )
return;
$indent = str_repeat("\t", $depth);
$output .= "$indent</ul>\n";
}
/**

*
* @see Walker::start_el()
* @since 2.1.0
*
* @param string $output Passed by reference. Used to append additional content.
* @param int $depth Depth of category in reference to parents.
* @param integer $current_object_id
*/
public function start_el( &$output, $cat, $depth = 0, $args = array(), $current_object_id = 0 ) {
$output .= '<li class="cat-item cat-item-' . $cat->term_id . ' cat-count-' . $cat->count;
if ( $args['current_category'] == $cat->term_id ) {
$output .= ' current-cat';
}
if ( $args['has_children'] && $args['hierarchical'] ) {
$output .= ' cat-parent';
}
if ( $args['current_category_ancestors'] && $args['current_category'] && in_array( $cat->term_id, $args['current_category_ancestors'] ) ) {
$output .= ' current-cat-parent';
}
$output .= '"><a href="' . get_term_link( (int) $cat->term_id, $this->tree_type ) . '">' . _x( $cat->name, 'product category name', 'woocommerce' ) . '</a>';
if ( $args['show_count'] ) {
$output .= ' <span class="count">(' . $cat->count . ')</span>';
}
}
/**
* Ends the element output, if needed.
*
* @see Walker::end_el()
* @since 2.1.0
*
* @param string $output Passed by reference. Used to append additional content.
* @param int $depth Depth of category. Not used.
* @param array $args Only uses 'list' for whether should append to output.
*/
public function end_el( &$output, $cat, $depth = 0, $args = array() ) {
$output .= "</li>\n";
}
/**

*

*/
public function display_element( $element, &$children_elements, $max_depth, $depth = 0, $args, &$output ) {
if ( ! $element || ( 0 === $element->count && ! empty( $args[0]['hide_empty'] ) ) ) {
return;
}
parent::display_element( $element, $children_elements, $max_depth, $depth, $args, $output );
}
}
3-然后,您可以继续在样式文件中执行您想要的操作,通常是style.css
。在这种情况下,我们希望隐藏计数为1的项目,因此我们添加:
.cat-count-1 {
display: none;
}
