PHP: Getting insert confirmation on prepared statement - php

Question

I am a newbie to prepared statements and trying to get something simple to work.
This is my DB table:
`unblocker_users` (
`uno` bigint(20) NOT NULL AUTO_INCREMENT,
`user_email` varchar(210) DEFAULT NULL,
`pw_hash` varchar(30) DEFAULT NULL,
`email_confirmed` tinyint(4) DEFAULT NULL,
`total_requests` bigint(20) DEFAULT NULL,
`today_date` date DEFAULT NULL,
`accessed_today` tinyint(4) DEFAULT NULL,)
and this is my function to insert some test data
function add_new_user($e_mail1)
{
require_once "db.php";
$stmt = $mysqli->prepare("INSERT INTO unblocker_users VALUES ('',?, ?,0,0,?,0)");
$stmt->bind_param('sss', $e_mail1, $this->genRandomString(1),$this->today_date());
$stmt->execute();
$stmt->close();
// ####### Below line is giving an error ########
$done = $stmt->affected_rows;
return $done;
}
As you can see above, i have marked the line that is giving me an error.
Warning: unblocker_class::add_new_user() [unblocker-class.add-new-user]: Property access is not allowed yet in...
Where did I go wrong?
How can i get some sort of confirmation that a row has been inserted successfully?
Thanks!

Answer 1

you close the prepared statement BEFORE you want to access its affected rows
$done = $stmt->affected_rows;
$stmt->close();
return $done;
