Answer 1

您的问题似乎是您没有将值绑定到查询中：

$stmt = parent::query($sql);
$stmt->bindValue( ':searchQ', $_POST['searchimpexp'], PDO::PARAM_STR );

Answer 2

代码：

    $sql = array( ':searchQ' => $_POST['searchimpexp'] . '%' );
    $sql = "SELECT distinct username as suggest, user_id
            FROM login_users
            WHERE username LIKE :searchQ
            OR name LIKE :searchQ
            OR user_id LIKE :searchQ
            ORDER BY username
            LIMIT 0, 5";

    $stmt = parent::query($sql);

仅设置

$stmt = parent::query("SELECT distinct username as suggest, user_id
                FROM login_users
                WHERE username LIKE :searchQ
                OR name LIKE :searchQ
                OR user_id LIKE :searchQ
                ORDER BY username
                LIMIT 0, 5");

设置数组的$ sql没用，因为当$ sql设置select语句时它被覆盖。

参数号无效：绑定变量数与令牌数不匹配意味着查询中的nr个变量不是赋予PDO对象的值的数量。我不确定parent :: query的功能是什么，但应该使用prepare语句。

您必须执行类似

的操作

<?php

$statement = parent::query-prepare("SELECT distinct username as suggest, user_id
                    FROM login_users
                    WHERE username LIKE :searchQ
                    OR name LIKE :searchQ
                    OR user_id LIKE :searchQ
                    ORDER BY username
                    LIMIT 0, 5");
$statement->execute(array(':searchQ' => $_POST['searchimpexp'] . '%'));     
$row = $statement->fetchAll();

?>
