我试图了解MySQL中的绑定参数。我尝试了这个测试,但是我得到了错误"在非对象上调用成员函数bind_param()"。
我做错了吗?
以下是更新后的代码:
$sql = "INSERT INTO users (field1, field2, field3) VALUES (?, ?, ?)";
connect();
$stmt = $conn->prepare($sql);
$stmt->bind_param("sss", $value1, $value2, $value3);
$value1 = "test1";
$value2 = "test2";
$value3 = "test3";
$stmt->execute();
以下是connect()
功能:
function connect(){
global $conn;
$conn = new mysqli(DBHOST, DBUSER, DBPASS, DBNAME);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
}
答案 0 :(得分:2)
要在PDO中准备好的查询中绑定params,将包含params的数组传递给execute函数:
$result = $conn->prepare($sql);
$result->execute(array($value1, $value2, $value3));
<强>更新强>
对于mysqli版本:
connect();
$result = $conn->prepare($sql);
$result->bind_param('sss', $value1, $value2, $value3);
$result->execute();
