我在php中创建了表单，并希望更新sql server数据库中的数据。
以下是我的ad.php文件。
<html>
<title>FORM</title>
<body><br><br>
<form action ="db_connection.php" method="post">
Activity:<input type="text" name="name"><br><br>
Units: <input id="number"><br><br>
<input type="submit" value="submit">
</form>
插入上述表格的数据应在数据库的“广告”表中更新。
以下是我的db_connection.php文件：
<?php
class DB{
protected static $db;
const SERVER = "";
const SCHEMA = "";
const USER = "";
const PASS = "";
/*
* Sets up the database connection
* @return the database instance
*/
public static function databaseConnection(){
if(!self::$db){
try {
$databse = "sqlsrv:server=" . self::SERVER . ";Database=" . self::SCHEMA;
self::$db = new PDO($databse, DB::USER, DB::PASS);
self::$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
} catch(PDOException $e){
die("Error " . $e->getMessage());
}
}
return self::$db;
}
}
class ad{
public function dbAdmin(vat $Activity, int $Units): bool {
$conn = databaseConnection::getConnection();
$conn->beginTransaction();
$sql = "INSERT INTO ad('Activity', 'Units') VALUES (:Activity, :Units)";
$stmt = $conn->prepare($sql);
$stmt->bindParam(':Units', $Units);
$stmt->bindParam(':Activity', $Activity);
if ($stmt->execute()) {
$conn->commit();
return true;
} else {
$conn->rollback();
return false;
}
}
}
我在提交表单后得到一个空白页面，并且数据库没有使用提交的新数据进行更新。你可以检查代码并帮我纠正。
我不得不使用Docker重现这个。正在使用容器“microsoft / mssql-server-linux”。
I am using this extension **pdo_sqlsrv** and this driver https://breeto.id.au/2017/05/docker-alpine-linux-php-sql-server/

你必须将name属性也放在单位字段中..表格通过其字段名称提交....
更正： -
<html>
<title>FORM</title>
<body><br><br>
<form action ="db_connection.php" method="post">
Activity:<input type="text" name="name"><br><br>
Units: <input id="number" name="number><br><br>
<input type="submit" value="submit">
</form>
我不确定你到底想要做什么，因为它是完全不完整的代码。
$_POST阵列在哪里？你如何以及在哪里检索POST请求数据？dbAdmin是执行数据插入的方法，但是如何调用此方法？你在哪里实例化类并调用这个方法？vat数据类型在这里声明dbAdmin(vat $Activity, int $Units)？name的Units属性。
