我是 PHP 世界的新手,我想问一下,如何在这段代码中添加更多产品 ID?
不幸的是,我不知道如何分隔多个 ID。
我想输入多个 ID,以便仅针对某些产品显示特定内容。
add_action( 'woocommerce_single_product_summary', 'add_custom_content_for_specific_product', 15 ); function add_custom_content_for_specific_product() { global $product; // Limit to a specific product ID only (Set your product ID below ) if( $product->get_id() != 37 ) return; // The content start below (with translatables texts) ?> <div class="custom-content product-id-<?php echo $product->get_id(); ?>"> <h3><?php _e("My custom content title", "woocommerce"); ?></h3> <p><?php _e("This is my custom content text, this is my custom content text, this is my custom content text…", "woocommerce"); ?></p> </div> <?php // End of content }
如果要在特定产品上显示内容,可以使用in_array():
add_action( 'woocommerce_single_product_summary', 'add_custom_content_for_specific_product', 15 ); function add_custom_content_for_specific_product() { global $product; /* Add the product ids to the array separated by commas that you want the content below to display on * in_array() arguments: * $product->get_id() is the needle - what you're looking for in the array * [1,2,3,4,5] are the product ids you want to show the content on. Replace those with your actual ids * TRUE just makes sure it's the same type of data. In this case we set it to TRUE, since $product->get_id() is an integer and so is the data in the array. */ if( in_array( $product->get_id(), [37,1,2,3,6,7], TRUE ) ) : // The content start below (with translatables texts) ?> <div class="custom-content product-id-<?php echo $product->get_id(); ?>"> <h3><?php _e("My custom content title", "woocommerce"); ?></h3> <p><?php _e("This is my custom content text, this is my custom content text, this is my custom content text…", "woocommerce"); ?></p> </div> <?php /* If the ids are not in the array above, return the function without output. */ else : return; endif; }
