WP_QUERY参数添加多个TAX_QUERY

我正在创建一个自定义搜索系统来搜索我的自定义帖子类型食谱，在搜索中它搜索人们选择的分类术语。

现在，由于它可以硬编码所有这些，我需要通过某种循环来构建args。

下面是一个代码示例，

$args = array(
\'post_type\'      => get_post_type(),
\'orderby\'        => \'menu_order\',
\'order\'          =>  \'ASC\',
\'posts_per_page\' => -1,
\'no_found_rows\'  => true,
\'tax_query\' => array(
    \'relation\' => \'AND\',
    array(
        \'taxonomy\' => \'product_category\',
        \'field\'    => \'slug\',
        \'terms\'    => array($category->slug), //Supply the current product_category terms
    ),
    array(
        \'taxonomy\' => \'product_locations\',
        \'field\'    => \'slug\',
        \'terms\'    => array($current_location), //Add the product_locations term
        \'operator\' => \'IN\',
    ),
),
);

我需要补充的是：

array(
        \'taxonomy\' => \'product_category\',
        \'field\'    => \'slug\',
        \'terms\'    => array($category->slug), //Supply the current product_category terms
    ),

我需要的是，当有人选择时，以编程方式添加它们。我曾尝试使用循环构建args数组，并将字符串添加到一起，但我无法使其工作。有没有人有什么快速的方法可以做到这一点？

$args = array( \'post_type\' => get_post_type(), \'orderby\' => \'menu_order\', \'order\' => \'ASC\', \'posts_per_page\' => -1, \'no_found_rows\' => true, \'tax_query\' => array(), ); if(condition){ $args[\'tax_query\'] = array( \'relation\' => \'AND\', array( \'taxonomy\' => \'product_category\', \'field\' => \'slug\', \'terms\' => array($category->slug), //Supply the current product_category terms ), array( \'taxonomy\' => \'product_locations\', \'field\' => \'slug\', \'terms\' => array($current_location), //Add the product_locations term \'operator\' => \'IN\', ), ), } else{ $args[\'tax_query\'] = array( array( \'taxonomy\' => \'product_category\', \'field\' => \'slug\', \'terms\' => array($category->slug), //Supply the current product_category terms ), ); }
