MySQL Question

Insert statement after user registration with loop

I have registration form which works fine. Now I want to add second query after user is registered. This query should have loop and add exactly 10 new rows in another table. This is the query with loop

if ($conn->query($sql) === TRUE) {
$result = "Request successfully submitted.";

$new_id = $db_con->lastInsertId();


$sql = "INSERT INTO new_customer (user_id,value1,value2) VALUES";

for($i=0;$i< $qty;$i++){
$sql .= "($new_id,'1','0')";
if($i < ($qty -1 )){
$sql .=",";

I'm not sure if this is correct way of doing this. After user is successfully registered I'm trying to get lastInsertId and loop and insert 10 new rows in

What is happening is that user is successfully registered but nothing is saved in
. What is the problem here?

You need to execute your inner query like below:-


Add it after inner for loop code.

Also if you are using mysqli_* then you need to use mysqli_insert_id:-

$new_id = $db_con->mysqli_insert_id;
