[英]Insert and update into multiple tables, MySQL
I've got two tables. 我有两张桌子。 I want to, when submitting a form, use parentcreate.php as action and with that file insert a couple of variables into the first table and at the same time update the other table with one of the variables.
我想在提交表单时使用parentcreate.php作为操作,并使用该文件在第一个表中插入几个变量,同时用其中一个变量更新另一个表。 I've searched online but the closest thing I found was inserting and updating a single table, not two different.
我已经在线搜索过,但发现最接近的是插入和更新单个表,而不是两个不同的表。
Thanks in advance. 提前致谢。
Update: 更新:
Here's the code I've got so far, as you can see it's just inserting into the first table. 这是到目前为止的代码,您可以看到它只是插入到第一个表中。
session_name('knine_settings_login');
session_set_cookie_params(1*1*1*15*60);
session_start();
mysql_connect('xxxx', 'xxxx', 'xxxx') or die(mysql_error());
mysql_select_db("xxxx") or die(mysql_error());
$ClassIDOne = mysql_real_escape_string($_POST["cidone"]);
$ClassIDTwo = mysql_real_escape_string($_POST["cidtwo"]);
$ClassIDThree = mysql_real_escape_string($_POST["cidthree"]);
$ClassIDFour = mysql_real_escape_string($_POST["cidfour"]);
$ClassIDFive = mysql_real_escape_string($_POST["cidfive"]);
$usr = $_SESSION["usr"];
mysql_query("SET NAMES 'utf8'") or die(mysql_error());
mysql_query("SET CHARACTER SET 'utf8'") or die(mysql_error());
$query="INSERT INTO knine_parent_db
SET usr = '$usr', ClassIDOne = '$ClassIDOne', ClassIDTwo = '$ClassIDTwo', ClassIDThree = '$ClassIDThree', ClassIDFour = '$ClassIDFour', ClassIDFive = '$ClassIDFive'";
I basically want to execute both these queries at the same time: 我基本上想同时执行这两个查询:
$query="INSERT INTO knine_parent_db
SET usr = '$usr', ClassIDOne = '$ClassIDOne', ClassIDTwo = '$ClassIDTwo', ClassIDThree = '$ClassIDThree', ClassIDFour = '$ClassIDFour', ClassIDFive = '$ClassIDFive'";
$query="UPDATE knine_settings_login
SET ClassID = '$usr' WHERE usr ='$usr'";
You should use PDO, and read this topic in PHP manual : Link to PDO::beginTransaction and this one and this one too 您应该使用PDO,并在PHP手册中阅读此主题: 链接到PDO :: beginTransaction以及该一个和这个
You should begin a new transaction, then do your requests, check if there was no error, then commit ! 您应该开始一个新事务,然后执行您的请求,检查是否没有错误,然后提交!
Once you use PDO::commit, the queries are backed to auto-commit mode, then you have to use again PDO::beginTransaction to set auto-commit off and do multiple queries into a single transaction. 一旦使用PDO :: commit,查询将返回到自动提交模式,然后您必须再次使用PDO :: beginTransaction来设置自动提交,并在单个事务中进行多个查询。
That how to do multiple requests in one transaction. 那如何在一个事务中做多个请求。
In your case, there is some code to help you : 就您而言,有一些代码可以帮助您:
$query1 = "INSERT INTO knine_parent_db
SET usr = :usr,
ClassIDOne = :ClassIDOne,
ClassIDTwo = :ClassIDTwo,
ClassIDThree = :ClassIDThree,
ClassIDFour = :ClassIDFour,
ClassIDFive = :ClassIDFive
";
$exec1 = [
':usr' => $_SESSION["usr"],
':ClassIDOne' => $_POST["cidone"],
':ClassIDTwo' => $_POST["cidtwo"],
':ClassIDThree' => $_POST["cidthree"],
':ClassIDFour' => $_POST["cidfour"],
':ClassIDFive' => $_POST["cidfive"],
];
$query2 = "UPDATE knine_settings_login
SET ClassID = :usr
WHERE usr = :usr
";
$exec2 = [':usr' => $_SESSION["usr"]];
$db_host = 'localhost';
$db_name = 'MyDatabase';
$db_user = 'user';
$db_pass = 'password';
$dsn = 'mysql:host='.$db_host.';dbname='.$db_name.';charset=utf8';
try
{
$PDO = new PDO($dsn, $db_user, $db_pass);
}
catch(PDOException $e)
{
// if dev mode
echo 'Database connection error : ' . $e->getMessage();
// if prod mode
//header('Location: /404.html');
//exit;
}
// begin of transaction
$PDO->beginTransaction();
$res1 = $PDO->prepare($query1);
$res2 = $PDO->prepare($query2);
if($res1->execute($exec1) && $res2->execute($exec2))
{
$PDO->commit();
}
else
{
$PDO->rollBack();
}
// end of transaction
Try and separate the statements this worked for me 尝试分开对我有用的陈述
// insert query execution
$sql = "INSERT INTO vendors (vendorId ,vendor_name, address, email, phone, category) VALUES
('$vendorId', '$vendor_name', '$address', '$email',
'$phone', '$category')
";
if ($mysqli - > query($sql) === true) {
echo "<script>alert('You have successfully registered');</script>";
} else {
echo "<script>alert('could not create shop something went wrong '); <
/script>";
$mysqli - > error;
}
// update query execution
$sql = "UPDATE users SET userType = 'vendor', vendor_name='$vendor_name'
WHERE id = '".$_SESSION['
id ']."'
";
if ($mysqli - > query($sql) === true) {
echo "<script>alert('update successfull ');</script>";
header("location:my-account.php");
} else {
echo "<script>alert('could not create shop something went wrong '); <
/script>"; $mysqli->error;
}
