blocks|key|9599|text|我还没有测试过它，但我希望像这样的东西应该可以完成这项工作。将此代码添加到functions.php文件中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|9600|add_action('woocommerce_before_shop_loop_item','custom_remove_loop_price');
function+custom_remove_loop_price(){
++++global+$product;

++++++++remove_action('woocommerce_after_shop_loop_item_title','woocommerce_template_loop_price',10);

I haven't tested it but I expect something like this should do the job. Add this to your functions.php file.

<pre><code>add_action('woocommerce_before_shop_loop_item','custom_remove_loop_price');
function custom_remove_loop_price(){
 global $product;
 if(!$product-&gt;price){
 remove_action('woocommerce_after_shop_loop_item_title','woocommerce_template_loop_price',10);
 }
}
</code></pre>

blocks|key|4517280|text|这个终于为我做到了(使用woocommerce+3.0.8)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4517281|function+cw_change_product_price_display(+$price+)+{
++++$clear+=+trim(preg_replace('/+%2B/',+'+',+preg_replace('/[%5EA-Za-z0-9+]/',+'+',+urldecode(html_entity_decode(strip_tags($price))))));
++++if($clear+==+"0+00"){
++++++return+'';
++++}
++++return+$price;
++}
++add_filter(+'woocommerce_get_price_html',+'cw_change_product_price_display'+);
++add_filter(+'woocommerce_cart_item_price',+'cw_change_product_price_display'+);|code-block|syntax|javascript|4517282|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This one finally did it for me (using woocommerce 3.0.8):

<pre><code>function cw_change_product_price_display( $price ) {
 $clear = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($price))))));
 if($clear == "0 00"){
 return '';
 }
 return $price;
 }
 add_filter( 'woocommerce_get_price_html', 'cw_change_product_price_display' );
 add_filter( 'woocommerce_cart_item_price', 'cw_change_product_price_display' );
</code></pre>

blocks|key|4517299|text|这是另一种方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4517300|add_filter(+'woocommerce_get_price_html','maybe_hide_price',10,2);
function+maybe_hide_price($price_html,+$product){

++++++++++return+$price_html;
+++++}
+++++return+'';

Here's another approach:

<pre><code>add_filter( 'woocommerce_get_price_html','maybe_hide_price',10,2);
function maybe_hide_price($price_html, $product){
 if($product-&gt;get_price()&gt;0){
 return $price_html;
 }
 return '';
 }
</code></pre>

 }
 return '';
 } 
// End of above code

blocks|key|9705|text|尝试了Jared的答案，但就像有人说的那样，一旦满足条件，它就会删除所有价格。最终，我使用了这个解决方案，如果价格为0，则删除操作，如果不为0，则添加回来。看起来很有效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|9706|public+function+woocommerce_after_shop_loop_item_title_remove_product_price(){
++++global+$product;
++++$price+=+floatval(+$product->get_price()+);

++++++++remove_action('woocommerce_after_shop_loop_item_title',+'woocommerce_template_loop_price',+10);
++++}else{
++++++++add_action('woocommerce_after_shop_loop_item_title',+'woocommerce_template_loop_price',+10);
++++}
}

add_action(+'woocommerce_after_shop_loop_item_title',+'category_page_changes',+0+);|code-block|syntax|javascript|9707|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Tried Jared's answer but just as someone stated, it removed every price once the condition was met. Ultimately I went this solution where it removed the action if the price was 0 and added it back if it wasn't. Seems to work.

<pre><code>public function woocommerce_after_shop_loop_item_title_remove_product_price(){
 global $product;
 $price = floatval( $product-&gt;get_price() );
 if( $price &lt;= 0 ){
 remove_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10);
 }else{
 add_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10);
 }
}

add_action( 'woocommerce_after_shop_loop_item_title', 'category_page_changes', 0 );
</code></pre>

I'm busy with a wordpress/woocommerce site and I'd like to hide the price of an item when it's zero on the product category/archive page. 

I've tried looking on the web and in the php files but couldn't find where I should add the if statement. 

My php knowledge is pretty limited. I was wondering if someone else has experience with this or could help me in the right way 

Thanks!

我正在忙于一个wordpress/woocommerce网站，我想在产品类别/存档页面上隐藏商品的价格为零。我试着在web和php文件中查找，但是找不到我应该在哪里添加if语句。我的php知识相当有限。我想知道是否有人有这方面的经验，或者能以正确的方式帮助我。谢谢!
