php - How do i get the id of a row after i stored procedure -


i executed stored procedure inserts flight information table , wanted id after every insert made. not able find other ways work me. wanted flight_id on auto_increment.

mysqli_query($conn,"call addschedule('$airlineid','$from','$to','$departdate','$arrivedate','$departtime','$arrivaltime','$price')");  $last_id = mysqli_insert_id($conn); echo $last_id;

running mysqli_insert_id returns me value of 0 last flight id 3. can give me clear explanation?

mysqli_insert_id — returns auto generated id used in last query

the mysqli_insert_id() function returns id generated query on table column having auto_increment attribute. if last query wasn't insert or update statement or if modified table not have column auto_increment attribute, function return zero.

so please check had set auto_increment attribute id field.

or if had set auto_increment. sample code might you.

<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world");   $query = "insert mycity values (null, 'stuttgart', 'deu', 'stuttgart', 617000)"; $mysqli->query($query);  /* in op's case mysqli->query($conn,"call addschedule('$airlineid','$from','$to','$departdate','$arrivedate','$departtime','$arrivaltime','$price')"); */  printf ("new record has id %d.\n", $mysqli->insert_id);   /* close connection */ $mysqli->close(); ?>

answer 2

in sp 

insert table values (null, 'stuttgart', 'deu', 'stuttgart', 617000); select last_insert_id();

in php code

$result=mysqli_query($conn,"call addschedule('$airlineid','$from','$to','$departdate','$arrivedate','$departtime','$arrivaltime','$price')");  echo "last id: ".$result;

this might work.

ps: didn't test code. hope work
