带有单选按钮的 PHP 搜索查询

Question

我正在尝试向我的搜索查询中添加一个可用绘图的新语句（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。

问候

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' ] 并且搜索查询不起作用。

更新：

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

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

我必须只显示可用的图。

Answer 1

替换这一行：

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

用这个：

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

Answer 2

您不应该使用 tax_query 来按字词搜索吗？ 据我了解，您需要一个 tax_query。

试试这个更新版本的$args：

$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，因此如果您使用 slug，您可能希望保留原样，或者如果您使用 id 则将其删除（因为默认值是term_id)。
