复选框字段不过滤表单 acf 字段

Question

我使用了 ACF 复选框字段。现在我想过滤查询是这个复选框字段。然后我试图从前端搜索。但它没有显示任何结果。字段 meta_key 是 cotf。 acf fields screenshot 1

acf fields screenshot 2

<form action="" id="" method="POST">
<input type="checkbox" name="ap_features[]" value="air_conditioning">
<input type="checkbox" name="ap_features[]" value="washer_connections">
<input type="checkbox" name="ap_features[]" value="refrigerator">
<input  class="btn btn-lg  btn-success" type='submit' id="" name="submit" value="SEARCH">
</form>

PHP

<?php
    if(isset($_POST['submit'])){
        $afeatures = $_POST['ap_features'];
        $args = array(  
            'numberposts'   => -1,
            'post_type'     => 'apartment',
            'meta_query'    => array(
            'relation'      => 'AND',
                array(
                    'key'       => 'cotf',
                    'value' => array($afeatures),
                    'compare'   => 'IN'
                )
            )
        );
    }
?>

我也试过这段代码，但它不起作用：

$meta_query = array('relation' => 'OR');
    foreach ($_POST['ap_features'] as $value) {
      $meta_query[] = array(
      'key' => 'cotf',
      'value' => '"'.$value.'"',
      'compare' => 'LIKE'
      )
    }
    $args = array(
      'numberposts' => -1,
      'post_type' => 'restaurant',
      'meta_query' => $meta_query
    );

你的代码应该是这样的。

if(isset($_POST['submit'])){

    $args = array(  
        'numberposts'   => -1,
        'post_type'     => 'apartment',            
    );
    $afeatures = $_POST['ap_features'];

    if(is_array($afeatures)){
        $afeaturesArr = implode(",",$afeatures);

        $args['meta_query']= array(
        'relation'=>array('AND',
            array(
            'key'       => 'cotf',
            'value' => explode(",",$afeaturesArr),
            'compare'   => 'IN'
            )            
        ));
    }
}
