php - 在 WordPress 中的 foreach 循环内选择查询

Question

如何在 foreach 循环中实现选择查询我从数组中选择 ids 并在选择查询中传递

$query_user= "SELECT user_id FROM wp_usermeta WHERE meta_key='devstate' AND meta_value='$user_state'";
$query_value= $wpdb->get_row($query_user, OBJECT);
$user_id_value= $query_value->user_id;
$result = $wpdb->get_results($query_user) or die(mysql_error());


foreach( $result as $results ) {
    $id=$results->user_id;
    echo $id;
    $my_query="SELECT * FROM $table where ID='$id'";
    $val123= $wpdb->get_row($my_query, OBJECT);
         $email123= $val123->user_email;
         echo $email123;
         echo $val123->user_email;

}

Answer 1

您是否尝试过像这样传递变量:

$my_query="SELECT * FROM $table where ID=". $id;

或者尝试像这样转储选择变量:

echo($my_query);
