Checking INSERT in mysqli_multi_query() Procedural - php

Question

I have a project file, and i have trouble at my syntax, example:
mysqli_query($connection,"START TRANSACTION");
$mysql_query = mysqli_multi_query($connection,"
INSERT INTO `TABLE 1` (`ID`, `VAL`) VALUES (NULL, 'NAMBAH 1');
INSERT INTO `TABLE 2` (`ID`, `VAL`) VALUES (NULL, 'NAMBAH 2');
INSERT INTO `TABLE 3` (`ID`, `VAL`) VALUES (NULL, 'NAMBAH 3');
");
if(!$mysql_query){
echo "Syntax MySQL: " . mysqli_error($connection);
}else{
do{
// Store first result set
if ($result=mysqli_store_result($connection)){
mysqli_free_result($result);
}
}while (mysqli_next_result($connection));
}
if imposible, i want to rollback if one MySQL Query is failed to inserted, i think we can check one by one for this query,
thanks for advance!.

Answer 1

It should be something like this:
mysqli_autocommit($connection, FALSE);
$mysql_query = mysqli_multi_query($connection,"
INSERT INTO `TABLE 1` (`ID`, `VAL`) VALUES (NULL, 'NAMBAH 1');
INSERT INTO `TABLE 2` (`ID`, `VAL`) VALUES (NULL, 'NAMBAH 2');
INSERT INTO `TABLE 3` (`ID`, `VAL`) VALUES (NULL, 'NAMBAH 3');
");
do{
// Store first result set
if ($result=mysqli_store_result($connection)){
mysqli_free_result($result);
}
}while (mysqli_next_result($connection));
if( $mysqli_errno($connection)){
$mysqli_commit($connection);
}else{
echo "MySQL Error: " . mysqli_error($connection);
$mysqli_rollback($connection);
}
