我试图有条件地将参数馈送到wordpress循环中，因此希望根据过滤器系统提供的标记、类别或属性添加到参数中。

然而，我似乎不知道如何使用$arg将tax\\u查询添加到参数中=

例如，我想更改以下代码：

  if ($value[\'priceRange\'] == 0 && $value[\'tags\'] == 0 && !$value[\'type\']) {
    if(!$value[\'priceRange\']) {
      $value[\'priceRange\'] = array(0,1000000);
    }

    $args = array(
     \'post_type\' => \'product\',
     \'posts_per_page\' => -1,
    );
  }



  if ($value[\'priceRange\'] == 0 && $value[\'tags\'] != 0 && !$value[\'type\']) {
    $args = array(
      \'post_type\' => \'product\',
      \'posts_per_page\' => -1,
      \'tax_query\' => array(
        \'relation\' => \'OR\',
        array(
          \'taxonomy\' => \'product_tag\',
          \'field\' => \'slug\',
          \'terms\' => $value[\'tags\'],
        ),
        array(
          \'taxonomy\' => \'product_cat\',
          \'field\' => \'slug\',
          \'terms\' => $value[\'tags\'],
        ),
        array(
          \'taxonomy\' => \'pa_branding\',
          \'field\' => \'slug\',
          \'terms\' => $value[\'tags\'],
        ),
      ),
    );
  }

为此：

  if ($value[\'priceRange\'] == 0 && $value[\'tags\'] == 0 && !$value[\'type\']) {
    if(!$value[\'priceRange\']) {
      $value[\'priceRange\'] = array(0,1000000);
    }

    $args = array(
     \'post_type\' => \'product\',
     \'posts_per_page\' => -1,
    );
  }



  if ($value[\'priceRange\'] == 0 && $value[\'tags\'] != 0 && !$value[\'type\']) {
    $args .= 
      \'tax_query\' => array(
        \'relation\' => \'OR\',
        array(
          \'taxonomy\' => \'product_tag\',
          \'field\' => \'slug\',
          \'terms\' => $value[\'tags\'],
        ),
        array(
          \'taxonomy\' => \'product_cat\',
          \'field\' => \'slug\',
          \'terms\' => $value[\'tags\'],
        ),
        array(
          \'taxonomy\' => \'pa_branding\',
          \'field\' => \'slug\',
          \'terms\' => $value[\'tags\'],
        ),
      ),
    );
  }

稍后，我还计划在此基础上添加一个针对价格的条件meta\\u查询。

有人有什么建议吗？

提前感谢！
