zencart通过产品id 批量添加推荐产品

1.修改 admin/featured.php

查找 pre_add_confirmation

将 pre_add_confirmation 与  break; 之间的代码，用下面的代码替换即可

<?php
 
 case 'pre_add_confirmation':
      // check for blank or existing featured

        $pre_add_products_id=$_POST['pre_add_products_id'];
        $pre_add_products_id2=explode(',',$pre_add_products_id);
        foreach($pre_add_products_id2 as $key=>$val) {
            $sql = "select products_id from " . TABLE_PRODUCTS . " where products_id='" . (int)$val . "'";
            $check_featured = $db->Execute($sql);
            if ($check_featured->RecordCount() == 1) {
                $sql = "select products_id from " . TABLE_FEATURED . " where products_id='" . (int)$val . "'";
                $check_featured = $db->Execute($sql);
                if ($check_featured->RecordCount() < 1) {
                    // add empty featured
                    $featured_date_available = ((zen_db_prepare_input($_POST['start']) == '') ? '0001-01-01' : zen_date_raw($_POST['start']));
                    $expires_date = ((zen_db_prepare_input($_POST['end']) == '') ? '0001-01-01' : zen_date_raw($_POST['end']));
                    $products_id = zen_db_prepare_input($val);
                    $db->Execute("insert into " . TABLE_FEATURED . " (products_id, featured_date_added, expires_date, status, featured_date_available)
                        values ('" . (int)$products_id . "', now(), '" . zen_db_input($expires_date) . "', '1', '" . zen_db_input($featured_date_available) . "')");
                }
            }     
        }
        break;
?>

2.adminincludesfunctionsgeneral.php

查找 函数 zen_set_field_length

在这个函数下面 增加以下函数即可

  function zen_set_field_length_1000($max=50, $override=false) {
    $field_length= 1000;
    switch (true) {
      case (($override == false and $field_length > $max)):
        $length= 'size = "' . ($max+1) . '" maxlength= "' . $field_length . '"';
        break;
      default:
        $length= 'size = "' . ($field_length+1) . '" maxlength = "' . $field_length . '"';
        break;
    }
    return $length;
  }

3. 做完上面2步后 就可以 通过后台 Catalog --> Featured Products --> 点击右边的 Product ID to be Manually Added as a Featured按钮
然后在文本框中输入产品的id, 产品id之间用英文逗号隔开，列如 21,55,23,89
