wordpress $ wpdb-＆gt; getresults with SELECT .. WHERE .. IN

Question

我一直在尝试使用SELECT .. WHERE .. IN

global $wpdb;         
$sql = "SELECT * FROM wp_search WHERE name IN ('s','w','a')";  

$result = $wpdb->get_results ( $sql );
if ( $result )
{
   print_r($result);
}

但它失败并返回错误。有没有替代这个Select语句或我需要做的任何其他事情来使这个功能按预期进行？

您的代码对我来说绝对正常但是您可以参考此替代

global $wpdb;

$special_entries = array( 'inherit', 'auto-draft', 'unanswered' );
$how_many = count($special_entries);
$placeholders = array_fill(0, $how_many, '%s');

$format = implode(', ', $placeholders);

$query = "SELECT * FROM $wpdb->posts WHERE post_status IN($format)";

$results = $wpdb->get_results( $wpdb->prepare($query, $special_entries) );
