问题描述
我正在尝试从循环中删除名为“插座”的产品类别字词,而我看到了这篇帖子Exclude a WooCommerce product category from a WP_Query
我在代码中尝试过,但是缺少一些东西,有没有办法删除特定的产品类别?
<?PHP
$get_parents_cats = array(
'taxonomy' => 'product_cat','parent' => 0,'number' => '9','hide_empty' => false,'tax_query' => array(
'taxonomy' => 'category','field' => 'slug','terms' => array( 'outlet' ),'operator' => 'NOT IN',),);
$categories = get_categories( $get_parents_cats );
foreach ($categories as $cat) {
$cat_id = $cat->term_id;
$cat_link = get_category_link( $cat_id );
$term_link = get_term_link( $cat->term_id );
$thumbnail_id = get_woocommerce_term_Meta( $cat->term_id,'thumbnail_id',true ); // Get Category Thumbnail
$image = wp_get_attachment_url( $thumbnail_id );
if ( $image ) {?>
<div class="wrapper">
<img src="<?PHP echo $image; ?>"/>
<a href="<?PHP echo get_term_link($cat->slug,'product_cat') ?>">
<div class="title">
<h3><?PHP echo $cat->name; ?></h3>
</div>
</a>
</div>
<?PHP
}
wp_reset_query();}
?>
解决方法
您的代码中存在一些错误和遗漏的东西。请尝试以下操作:
<?php
$taxonmomy = 'product_cat';
$exclude_slug = 'outlet';
$exclude_id = $term_name = get_term_by( 'slug',$exclude_slug,$taxonmomy )->term_id; // term Id to be excluded
// Get the array of top level product category WP_Terms Objects
$parents_terms = get_terms( array(
'taxonomy' => $taxonmomy,'parent' => 0,'number' => 9,'hide_empty' => 0,'exclude' => $exclude_id,) );
// Loop through top level product categories
foreach ($parents_terms as $term) {
$term_id = $term->term_id;
$term_name = $term->name;
$term_link = get_term_link( $term,$taxonmomy );
$thumb_id = get_woocommerce_term_meta( $term_id,'thumbnail_id',true ); // Get term thumbnail id
// Display only product categories that have a thumbnail
if ( $thumb_id > 0 ) :
$image_src = wp_get_attachment_url( $thumb_id ); // Get term thumbnail url
?>
<div class="wrapper">
<img src="<?php echo $image_src; ?>"/>
<a href="<?php echo $term_link ?>">
<div class="title">
<h3><?php echo $term_name; ?></h3>
</div>
</a>
</div>
<?php
endif;
}
?>
经过测试可以正常工作。
