PHP update multiple tables in one statement error - php

Question

I have tried many solutions that I have found on stackoverflow but keep getting the same error when trying to update my tables within the one statement.
ERROR:
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'WHERE docID=7' at line 2
Code:
<?php
if(isset($_POST['btn-revActivate']))
{
try
{
$database = new Database();
$db = $database->dbConnection();
$conn = $db;
$stmt=$conn->prepare("UPDATE tbl_revisions, tbl_documents SET revStatus='Active', docStatus='Draft'
WHERE revID=$rid AND docID=$docID ");
$stmt->bindparam("revStatus",$revStatus);
$stmt->bindparam(":id",$rid);
$stmt->bindparam("docStatus",$docStatus);
$stmt->bindparam(":docID",$docID);
$stmt->execute();
return true;
}
catch(PDOException $e)
{
echo $e->getMessage();
return false;
}
}
?>
Can someone please help as I don't know what is wrong with this statement.
Thanks.

You can't update multiple tables in one statement.if you want to update then you can use a transaction to make sure that two UPDATE statements are treated atomically.
BEGIN TRANSACTION;
UPDATE tbl_revisions
SET revStatus='Active', docStatus='Draft'
WHERE revID=$rid AND docID=$docID ';
UPDATE tbl_documents
SET revStatus='Active', docStatus='Draft'
WHERE revID=$rid AND docID=$docID ';
COMMIT;
