我制作了一个带有选择框和文本字段的自定义搜索表单。

我有一个选择框，上面有“租赁”和“出售”（这是一个房地产网站）等选项。还有输入字段，用于最低和最高价格、位置等。

在帖子中，我为所有这些过滤器设置了自定义字段。

我用了WP_查询。它应该会起作用。以下是查询：

// Define the arguments for the WP query
$args = array(
        \'post_type\' => \'post\',
        \'relation\' => \'AND\',
        \'meta_query\' => array(
                array(
                        \'key\' => \'ex_lokacija\',
                        \'value\' => $grad ,
                        \'compare\' => \'LIKE\'
                ),
                array(
                        \'key\' => \'ex_vrsta_oglasa\',
                        \'value\' => $adType ,
                        \'compare\' => \'LIKE\'
                ),
                array(
                        \'key\' => \'ex_tip_nekretnine\',
                        \'value\' => $realEstateType ,
                        \'compare\' => \'LIKE\'
                ),
                array(
                        \'key\' => \'ex_dio_pg\',
                        \'value\' => $dioGrada ,
                        \'compare\' => \'LIKE\'
                ),
                array(
                        \'key\' => \'ex_dio_pg\',
                        \'value\' => $dioGrada ,
                        \'compare\' => \'LIKE\'
                ),
                array(
                        \'key\' => \'et_square_footage\',
                        \'value\' => array( $squareFrom, $squareTo ),
                        \'type\' => \'numeric\',
                        \'compare\' => \'BETWEEN\'
                ),
                array(
                        \'key\' => \'et_price\',
                        \'value\' => array( $priceFrom, $priceTo ),
                        \'type\' => \'numeric\',
                        \'compare\' => \'BETWEEN\'
                ),
                array(
                        \'key\' => \'et_bedrooms_number\',
                        \'value\' => $roomsNum,
                        \'type\' => \'numeric\',
                        \'compare\' => \'LIKE\'
                )
        )
);

$searched_posts = new WP_Query( $args );

我对每个$\\u GET vars使用preg\\u replace，并将它们分配给您在“value”中看到的变量。

现在，问题是它没有显示任何东西，即使应该有结果。

此外，如果没有“s”字段，它将无法工作-必须在其中添加一些内容，以便加载空的结果页。

Possible problem #1

我猜我创建的循环有一个问题，如下所示：

                    while ($searched_posts->have_posts()) : $searched_posts->the_post(); ?>



                        <?php the_title(); ?>
                        <?php the_content(); ?>



                    <?php endwhile; ?>

这只是为了测试。

Possible problem #2

我把所有这些都放在一个文件中——搜索。php。也许这会引起问题？

这是：

\'\'第

global $wpdb;

$grad           = preg_replace( \'/^[0-9a-zA-Z-]/\', \'\', $_GET[\'grad\'] );
$adType         = preg_replace( \'/^[0-9a-zA-Z-]/\', \'\', $_GET[\'adType\'] );
$realEstateType = preg_replace( \'/^[0-9a-zA-Z-]/\', \'\', $_GET[\'realEstateType\'] );
$dioGrada       = preg_replace( \'/^[0-9a-zA-Z-]/\', \'\', $_GET[\'dioGrada\'] );
$squareFrom     = preg_replace( \'/[^0-9]/\', \'\', $_GET[\'squareFrom\'] );
$squareTo       = preg_replace( \'/[^0-9]/\', \'\', $_GET[\'squareTo\'] );
$priceFrom      = preg_replace( \'/[^0-9]/\', \'\', $_GET[\'priceFrom\'] );
$priceTo        = preg_replace( \'/[^0-9]/\', \'\', $_GET[\'priceTo\'] );
$roomsNum       = preg_replace( \'/[^0-9]/\', \'\', $_GET[\'roomsNum\'] );

// Change the defaults if not chosen
if($squareFrom == \'\') { $squareFrom = \'0\'; }
if($squareTo == \'\') { $squareTo = \'10000000\'; }

// Define the arguments for the WP query
$args = array(
        \'post_type\' => \'post\',

                        \'compare\' => \'LIKE\'
                ),

                )
        )
);

$searched_posts = new WP_Query( $args );



 get_header(); ?>

感谢您查看我的问题！

$meta_query = array();
if (!empty($grad)) {
    $meta_query[] = array(
         \'key\' => \'ex_lokacija\',
         \'value\' => $grad ,
         \'compare\' => \'LIKE\'
    )
}
// and so on for each of your keys, then
$args = array(
        \'post_type\' => \'post\',
        \'relation\' => \'AND\',
        \'meta_query\' => $meta_query
