Question

尝试在我的搜索查询中添加一个可用于绘图的新语句（单选按钮值是或否）。你能告诉我，我的思维方式是否正确。非常感谢。

此致

if ( count( $_GET ) > 0 && isset( $_GET[ 'location' ] ) && isset( $_GET[ 'bedrooms' ] ) && isset( $_GET[ 'price' ] ) && isset($_GET[ 'plot_available' ]) == 'yes' ) {

                                    $location = $_GET[ 'location' ];
                                    $bedrooms = $_GET[ 'bedrooms' ];
                                    $price = $_GET[ 'price' ];
                                    $plot_available = $GET['plot_available'];

我添加了isset（$ _ GET ['plot_available']并且搜索查询无效。

我必须只显示可用的地块。

Answer 1

替换此行：

isset($_GET[ 'plot_available' ]) == 'yes'

用这个：

isset($_GET[ 'plot_available' ]) && ($_GET['plot_available'] == 'yes')

Answer 2

您是否应该使用tax_query按条款进行搜索？据我所知，你需要一个tax_query。

试用此$args的更新版本：

$args = array(
    'post_type' => 'development',
    'post_status' => 'publish',
    'posts_per_page' => '-1',
    'tax_query' => array(
        'relation' => 'AND', // not sure what is the case, could be OR
        array(
            'taxonomy' => 'location',
            'field' => 'slug',
            'terms' => $location
        ),
        array(
            'taxonomy' => 'bedrooms',
            'field' => 'slug',
            'terms' => $bedrooms
        ),
        array(
            'taxonomy' => 'price-range',
            'field' => 'slug',
            'terms' => $price
        ),
    )
);

我不确定$location，$bedrooms和$price的值，因此您可能希望保留原样，如果您使用的是slugs，或者如果您使用的话，请将其删除id＆＃39; s（因为默认为term_id）。
