Passing auto increment id to second query - php

Question

Currently I've got two queries, where the first one has an auto increment id. I would like to pass this id to my second query. But can't figure out how to do this. I've used 'mysqli_insert_id', but it returned in to the database.
This is my code:
$query = "INSERT INTO klanten (bedrijfsnaam) VALUES ('Some name')";
$last_id = mysqli_insert_id($con);
second_query = "INSERT INTO klantnotitie (login_id) VALUES ('" . $last_id . "')";
To avoid confusion: I want to insert to id of the first query into another table where it will just be an integer.
Hope someone can help me out!

Answer 1

Change your code like that
$query = "INSERT INTO klanten (bedrijfsnaam) VALUES ('Some name')";
mysqli_query($con, $query);
$last_id = mysqli_insert_id($con);
$second_query = "INSERT INTO klantnotitie (login_id) VALUES ('" . $last_id . "')";
mysqli_query($con, $second_query);

Answer 2

It will work in this way
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
mysqli_query($link, "CREATE TABLE myCity LIKE City");
$query = "INSERT INTO klanten (bedrijfsnaam) VALUES ('Some name')";
mysqli_query($link, $query);
printf ("New Record has id %d.\n", mysqli_insert_id($link));
$last_id = mysqli_insert_id($link);
second_query = "INSERT INTO klantnotitie (login_id) VALUES ('" . $last_id . "')";
mysqli_query($link, $second_query);
/* close connection */
mysqli_close($link);
?>

Assuming You are executing your queries,
1. You can use Mysql's function: LAST_INSERT_ID()
Example:
SELECT LAST_INSERT_ID();
2. You can use PHP's function mysqli_insert_id
Example:
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
//.. some code
$query = "INSERT INTO klanten (bedrijfsnaam) VALUES ('Some name')";
mysqli_query($link, $query);
printf ("New Record has id %d.\n", mysqli_insert_id($link));
