xampp MySQL Ignore - how to catch errors in PHP file - php

Question

I'm new in using transaction. My previous problem is about multiple inserts that should abort if one encounters an error and transaction with ignore solves it. My new problem is that I have to know if the insert is successful and if not should display the error.
PROFILE table
+--+----+---------+
|ID|NAME|BAL_LIMIT|
+--+----+---------+
NUMBER table
+--+----------+------+
|ID|PROFILE_ID|NUMBER|
+--+----------+------+
--TRANSACTION STATEMENT--
START TRANSACTION;
INSERT IGNORE INTO `PROFILE` (`ID`, `NAME`, `BAL_LIMIT`) VALUES(NULL, "Name", 0);
INSERT INTO `NUMBER` (`PROFILE_ID`, `NUMBER`) VALUES(LAST_INSERT_ID() , "09123456789");
COMMIT;
--ERROR TO BE HANDLED--
#1062 - Duplicate entry '09123456789' for key 'NUMBER_UNIQUE'
--PHP file contains--
$vname = $_POST["iname"];
$vbalancelimit = $_POST["ibalancelimit"];
$vnumber = $_POST["inumber"];
$transaction = "START TRANSACTION;
INSERT IGNORE INTO `PROFILE` (`ID`, `NAME`, `BAL_LIMIT`) VALUES(NULL, \"$vname\", $vbalancelimit);
INSERT INTO `NUMBER` (`ID`, `PROFILE_ID`, `NUMBER`) VALUES(NULL, LAST_INSERT_ID(), \"$vnumber\");
COMMIT;";
$execute_transaction = mysqli_multi_query($con,$transaction) or die("Error: ".mysqli_error($connection));
if (!$execute_transaction) {
echo mysqli_error($connection);
} else { echo "success"; }
The PHP file always shows success though having #1062 error and the inserts are ignored.

Multi-queried transaction statement problem solved.
Final PHP file:
<?php
$vname = $_POST["iname"];
$vbalancelimit = $_POST["ibalancelimit"];
$vnumber = $_POST["inumber"];
$transaction = "
START TRANSACTION;
INSERT IGNORE INTO `PROFILE` (`ID`, `NAME`, `BAL_LIMIT`) VALUES(NULL, \"$vname\", $vbalancelimit);
INSERT INTO `NUMBER` (`ID`, `PROFILE_ID`, `NUMBER`) VALUES(NULL, LAST_INSERT_ID(), \"$vnumber\");
COMMIT;";
$aff_rows = 0;
if(mysqli_multi_query($con,$transaction)){
do{$aff_rows+=mysqli_affected_rows($con);
}while(mysqli_more_results($con) && mysqli_next_result($con));
}if($aff_rows==2){//SUCCESS
echo "<script>swal(\"$vname\", \"New number: $vnumber\", \"success\");</script>";
}if($aff_rows==1){//WRONG NUMBER CORRECT NAME
echo "<script>swal(\"Duplicate entry of $vnumber\", \"Failed to add for: $vname\", \"error\");</script>";
}if($aff_rows==0){//WRONG NAME CORRECT/WRONG NUMBER
echo "<script>swal(\"Duplicate entry of $vname\", \"Failed to add number: $vnumber\", \"error\");</script>";}
?>
