如何激活價格過濾woocommerce沒有通過MIN_PRICE和MAX_PRICE URL

Question

我改變woocommerce核心查詢，並試圖基於自定義查詢字符串pro_type_sws展示產品= 32

現在，當我提供整個查詢字符串它的工作原理

WP /？MIN_PRICE = 35 & MAX_PRICE = 120 & post_type =產品& pro_type_sws = 32

但是當我只使用

localhost/wp /？post_type = product & pro_type_sws = 32

它不工作，我不知道如何激活價格過濾器代碼，而不使用小部件過濾器按鈕。

總之我想在產品頁面上應用過濾器，因此它只顯示那些與woocommerce的自定義產品數據類型相關的產品。

代碼中更改：類-WC-query.php

if ((isset($_GET['max_price']) && isset($_GET['min_price'])) or isset($_GET['pro_type_sws'])) { 


     $matched_products = array(); 
     $min = floatval($_GET['min_price']); 
     $max = floatval($_GET['max_price']); 
      $pro_type = $_GET['pro_type_sws']; 

      /* 
       Applying Filter based on product type query string 
      * If Product type query string set then render only those products which are related to given product data type. 
      */ 
      if (isset($pro_type)){ 
       // Query Update : Product type based filter applied through $pro_type query string 
       $matched_products_query = apply_filters('woocommerce_price_filter_results', $wpdb->get_results($wpdb->prepare(" 
      SELECT DISTINCT ID, post_parent, post_type FROM $wpdb->posts 
      INNER JOIN $wpdb->postmeta ON ID = post_id 
          LEFT JOIN wp_term_relationships AS rel ON object_id = post_id 
      WHERE post_type IN ('product', 'product_variation') AND post_status = 'publish' AND meta_key = %s AND meta_value BETWEEN %d AND %d AND rel.term_taxonomy_id = %d 
     ", '_price', $min, $max, $pro_type), OBJECT_K), $min, $max); 

      } 
      else{ 
       $matched_products_query = apply_filters('woocommerce_price_filter_results', $wpdb->get_results($wpdb->prepare(" 
      SELECT DISTINCT ID, post_parent, post_type FROM $wpdb->posts 
      INNER JOIN $wpdb->postmeta ON ID = post_id 
      WHERE post_type IN ('product', 'product_variation') AND post_status = 'publish' AND meta_key = %s AND meta_value BETWEEN %d AND %d 
     ", '_price', $min, $max), OBJECT_K), $min, $max); 

      } 


     if ($matched_products_query) { 
      foreach ($matched_products_query as $product) { 
       if ($product->post_type == 'product') 
        $matched_products[] = $product->ID; 
       if ($product->post_parent > 0 && ! in_array($product->post_parent, $matched_products)) 
        $matched_products[] = $product->post_parent; 
      } 
     }

更改核心文件是不是一個好主意，在每次更新（和廁所每年有很多），你必須申請您的mods再次。

嘗試掛鉤相同的過濾器（上一個自定義插件或主題的functions.php），做你的東西：

add_filter('loop_shop_post_in', function(){ 
    if (
     (isset($_GET['max_price']) && isset($_GET['min_price'])) 
     or isset($_GET['pro_type_sws']) 
    ){ 
     // do your thing 
     // adjust the issets to integrate to WC behavior 
     // etc 
    } 
});
