php - mysqli_stmt::execute() 需要 0 个参数，1 个给定

Question

我在 MyFile.php 中有这段代码

$db= mysqli_connect("host","user","pw","db");//connect to db
if (mysqli_connect_errno($con))//check connection
{echo "Failed to connect to MySQL: " . mysqli_connect_error();}
//Create a token for the unique link
$title= $_GET[apt_title];
$email= $_GET[mail_address];
$token = sha1(uniqid($email, true));
$time = $_SERVER["REQUEST_TIME"];
//prepare the query to be executed
$query = $db->prepare(
"INSERT INTO pending_users (email, token, title_apt, tstamp) VALUES (?, ?, ?, ?)"
);
$query->execute(
array(
    $title,
    $email,
    $token,
    $time
)
);

错误信息：

警告：mysqli_stmt::execute() 需要 0 个参数，1 个在 /websites 中给出

我应该如何调用execute()正确的方法？

Answer 1

因为 mysqli::execute()不接受任何参数。在调用它之前，您必须准备查询，然后将参数绑定到查询。然后你必须调用该execute()方法。所以试试这样：

$query = $db->prepare(
"INSERT INTO pending_users (email, token, title_apt) VALUES (?, ?, ?, ?)"
);
$query->bind_param('ssss', $title, $email, $token, $time);
$query->execute();

Answer 2

您需要在执行查询之前绑定参数，以程序方式这样做

mysqli_stmt_execute($stmt);

如果您在绑定参数后以面向对象的方式进行操作

/* Execute the statement */
$stmt->execute();

Answer 3

如果您查看mysqli::execute()的手册，您会发现它不接受任何参数。

bool mysqli_stmt::execute ( 无效 )

相反，您应该使用mysqli::bind_param来绑定您的参数。
