我正在使用此代码进行meta\\u查询
$values = shortcode_atts( array(\'category\' => \'Test\',), $atts );
$args = array(
\'post_type\' => \'mytype\',
\'post_status\' => \'publish\',
\'meta_query\' => array(
array(
\'key\' => \'br_type\',
\'value\' => esc_attr($values[\'category\']),
\'compare\' => \'=\'
),
),
);
$query = new WP_Query( $args );
我如何分配br_type
到php变量?
