3 queries in 1 action that depends on each - php

Question

I have 3 queries named $stmt9, $stmt10 and $stmt11. I need to run the query in order, e.g. run 9, then 10, and finally 11. If there is something wrong, I want to rollback the queries that have been done, e.g. if the problem is on 10, it should rollback 9, or if on 11, then should roll back 10 and 9.
I have the following code, but when something is wrong, sometimes it still runs $stmt9 only, or $stmt9 and $stmt10 but not $stmt11.
How to fix it?
This is the update action:
$this->conn->beginTransaction();
$stmt9 = $this->conn->prepare("UPDATE tableONE SET condition= :condition WHERE `tb1_id`= :id LIMIT 1");
condition
$id = Check_Get_Param($_GET['id']);
$stmt9->bindParam(':condition' , $this->condition);
$stmt9->bindParam(':id' , $id, PDO::PARAM_INT);
$stmt9->execute();
$stmt10 = $this->conn->prepare("UPDATE tableTOW SET disterbute = :dis WHERE tb2_id = :tbl2id LIMIT 1");
$stmt10->bindParam(":counting", $this->counting, PDO::PARAM_INT);
$stmt10->bindParam(":tbl2id ", $this->tbl2id , PDO::PARAM_INT);
$stmt10->execute();
$stmt11 = $this->conn->prepare("DELETE FROM tableTHREE WHERE tb3_id = :id limit 1");
$stmt11->bindParam(":id",$id, PDO::PARAM_INT);
$stmt11->execute();
if($stmt9 && $stmt10 && $stmt11){
$this->conn->commit(); //This will save my changes
header('location:../success.php');
exit;
} else {
$this->conn->rollBack(); //This will undo your changes
echo '<meta http-equiv="refresh" content="0">'. $message;
}
}
}

What you are looking for is called a transaction.
I checked and it is implemented in pdo.
Example taken from the documentation:
<?php
/* Begin a transaction, turning off autocommit */
$dbh->beginTransaction();
/* Change the database schema and data */
$sth = $dbh->exec("DROP TABLE fruit");
$sth = $dbh->exec("UPDATE dessert
    SET name = 'hamburger'");
/* Recognize mistake and roll back changes */
$dbh->rollBack();
/* Database connection is now back in autocommit mode */
?>
