Question

我的侧边栏中有一个高级搜索表单。该操作设置为get_bloginfo（'home'），因此它应指向search.php（因为表单的id为“searchform”）

该搜索表单应按自定义元字段过滤结果。

我尝试并创建了这个search.php，

<?php
function get_reviews_by_custom_search() {
    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',
            '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'
                                    )
            )
    );

    $searched_posts = new WP_Query( $args );

    return $searched_posts;
}

$searched_posts = get_reviews_by_custom_search();       

     get_header(); ?>

        <div id="content-top">
            <div id="menu-bg"></div>
            <div id="top-index-overlay"></div>

            <div id="content" class="clearfix">
                <div id="main-area">
                    <?php get_template_part('includes/breadcrumbs'); 

                        foreach ($searched_posts as $searched_post) {

                            echo "<h1 class=\"entry-title\"><a href=\"" . get_permalink($searched_post->ID) . "\">" . $searched_post->post_title . "</a></h1>";

                            echo "Rating - " . get_post_meta($searched_post->ID,'rating',true) . "<br>";
                            echo "Audience - " . get_post_meta($searched_post->ID,'audience',true) . "<br>";
                            echo "Length - " . get_post_meta($searched_post->ID,'length',true) . "<br>";    

                            echo "<a href=\"" . get_permalink($searched_post->ID) . "\">Read More</a>";

                        }
                    ?>

                </div> <!-- end #main-area -->

                <?php get_sidebar(); ?>

    <?php get_footer(); ?>

我在线发现了大部分代码，我还在学习PHP。

第一部分是应该返回搜索帖子数组的函数。但是，代码的某些部分是错误的。

这里有几个选项：

1，你可能会看到一个很好的Wordpress plugin

2，您可以捕获搜索字词，然后在WP_QUERY：

中使用它

$s = $_POST['search_field'];
$my_query = new WP_Query('meta_value='.$s);

在Wordpress中搜索自定义元字段
