如何在Woocommerce中的single-product.php上检查产品是否属于某个类别？

在这种情况下,我认为get_categories()并不是您的最佳选择,因为它返回一个字符串,其中所有类别均列为锚标记,适合显示,但不适用于计算在代码中列出了类别.好的,所以您需要做的第一件事就是获取当前页面的产品/帖子对象(如果您还没有的话):

 global $post;
 

然后,您可以获取产品的产品类别术语对象(类别).在这里,我将类别术语对象转换为名为$categories的简单数组,这样更容易查看分配了哪些块.请注意,这将返回分配给产品的所有类别,而不仅仅是当前页面之一,即,如果我们位于/shop/audio/funzo/:

 $terms = wp_get_post_terms( $post->ID, 'product_cat' );
foreach ( $terms as $term ) $categories[] = $term->slug;
 

然后,我们只需要检查列表中是否包含类别:

 if ( in_array( 'audio', $categories ) ) {  // do something
 

将它们放在一起:

 <?php
global $post;
$terms = wp_get_post_terms( $post->ID, 'product_cat' );
foreach ( $terms as $term ) $categories[] = $term->slug;

if ( in_array( 'audio', $categories ) ) {
  echo 'In audio';
  woocommerce_get_template_part( 'content', 'single-product' );
} elseif ( in_array( 'elektro', $categories ) ) {
  echo 'In elektro';
  woocommerce_get_template_part( 'content', 'single-product' );
} else {
  echo 'some blabla';
}
 

希望这是您要寻找的并回答您的问题.

I don't think get_categories() is the best option for you in this case because it returns a string with all the categories listed as anchor tags, fine for displaying, but not great for figuring out in code what the categories are. Ok, so the first thing you need to do is grab the product/post object for the current page if you don't already have it:

global $post;

Then you can get the product category term objects (the categories) for the product. Here I'm turning the category term objects into a simple array named $categories so it's easier to see what slugs are assigned. Note that this will return all categories assigned to the product, not just the one of the current page, ie if we're on /shop/audio/funzo/:

$terms = wp_get_post_terms( $post->ID, 'product_cat' );
foreach ( $terms as $term ) $categories[] = $term->slug;

Then we just have to check whether a category is in the list:

if ( in_array( 'audio', $categories ) ) {  // do something

Putting it all together:

<?php
global $post;
$terms = wp_get_post_terms( $post->ID, 'product_cat' );
foreach ( $terms as $term ) $categories[] = $term->slug;

if ( in_array( 'audio', $categories ) ) {
  echo 'In audio';
  woocommerce_get_template_part( 'content', 'single-product' );
} elseif ( in_array( 'elektro', $categories ) ) {
  echo 'In elektro';
  woocommerce_get_template_part( 'content', 'single-product' );
} else {
  echo 'some blabla';
}

Hopefully this is what you were looking for and answers your question.

has_term 应该可以工作:

 if ( has_term( 'audio', 'product_cat' ) ) {

       echo 'In audio';
       woocommerce_get_template_part( 'content', 'single-product' );

} elseif ( has_term( 'elektro', 'product_cat' ) ) {

       echo 'In elektro';
       woocommerce_get_template_part( 'content', 'single-product' );

} else {
       echo 'some blabla';
}
 

has_term should work in this case:

if ( has_term( 'audio', 'product_cat' ) ) {

       echo 'In audio';
       woocommerce_get_template_part( 'content', 'single-product' );

} elseif ( has_term( 'elektro', 'product_cat' ) ) {

       echo 'In elektro';
       woocommerce_get_template_part( 'content', 'single-product' );

} else {
       echo 'some blabla';
}

值得注意的是,您可以通过调用数组来遍历选项列表,而不必假设很多情况下都需要通过其他elseif检查来弄乱代码.

 if( has_term( array( 'laptop', 'fridge', 'hats', 'magic wand' ), 'product_cat' ) ) :

// Do stuff here

else :

// Do some other stuff

endif;
 

It's worth noting that you can go through a list of options by calling an array rather than having to clutter up your code with lots of elseif checks, assuming you want to do the same thing with each category that is.

if( has_term( array( 'laptop', 'fridge', 'hats', 'magic wand' ), 'product_cat' ) ) :

// Do stuff here

else :

// Do some other stuff

endif;

这很古老,但以防万一人们仍然将WooThemes作为简单的解决方案:

 if ( is_product() && has_term( 'your_category', 'product_cat' ) ) {
    //do code
}
 

*将"您的类别"更改为您正在使用的任何内容.

以下是文档的链接: https://docs.woothemes.com/document/remov-product-content-based-on-category/

This is old but just in case people are still looking WooThemes as a simple solution:

if ( is_product() && has_term( 'your_category', 'product_cat' ) ) {
    //do code
}

*Change 'your_category' to whatever you are using.

Here is the link to the documentation: https://docs.woothemes.com/document/remov-product-content-based-on-category/

我将使用WC_Product类的get_categories()函数.

您可以在此处找到链接.

基本上在页面循环内调用该函数以返回与产品关联的类别.

I'd look at using the get_categories() function of the WC_Product class.

You can find the link to the documentation here.

Basically within the loop of the page call the function to return the categories associated with the product.
