问题描述
I'm getting:
Warning: mysqli_stmt::bind_result(): Number of bind variables doesn't match number of fields in prepared statement in E:XAMPPhtdocsaccountlib egister.php on line 73
When I use this code:
if($stmt = $conn -> prepare("INSERT INTO login(user, pass) VALUES(?, ?)")) {
/* Bind parameters s - string, b - blob, i - int, etc */
$stmt -> bind_param("ss", $user, $pw);
/* Execute it */
$stmt -> execute();
/* Bind results */
$stmt -> bind_result($user, $pw);
/* Close statement */
$stmt -> close();
$userId = $conn->insert_id;
}
I can't understand, why this happens every time, what is wrong in my code snippet?
解决方案
You are attempting to bind_result on a statement that is not returning any results.
Remove this line.
$stmt -> bind_result($user, $pw);
