Unable to update data in MySQL using PHP PDO Prepared - php

Question

This is my code:
<?php
$servername = "localhost";
$username = "root";
$password = "";
try {
$conn = new PDO("mysql:host=$servername;dbname=site", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// prepare sql and bind parameters
$stmt = $conn->prepare("UPDATE site_users SET users_email_verified = :users_email_verified WHERE users_email = :users_email ");
$stmt->bindParam(':users_email_verified', $users_email_verified,PDO::PARAM_STR);
$stmt->bindParam(':users_email',$_GET["email"],PDO::PARAM_STR);
$users_email_verified = "yes";
$stmt->execute();
echo "done";
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}
?>
But it does not update the record.
But If I write the email directly inside $user_email variable (manually), like this
$users_email = "xyz#example.com";
Then the code works.
I do not understand why? How to fix it?

Answer 1

You have set the binding to be INTEGERS instead of STRINGS here:
$stmt->bindParam(':users_email_verified', $users_email_verified,PDO::PARAM_INT);
$stmt->bindParam(':users_email',$_GET["email"],PDO::PARAM_INT);
You should use PDO::PARAM_STR instead.
It also appear that you're not reporting errors, so you should check your web server's error logs for additional information.
