SQL Update with form values not working - php

Question

I'm trying to update a table with the form values although it doesn't seem to be updating in the database and there are no errors either.
<?php
session_start();
if(!isset($_SESSION["user"]) or !is_array($_SESSION["user"]) or empty($_SESSION["user"])) {
// redirect to login page
}
$dbhost = "localhost";
$dbname = "***";
$dbuser = "***";
$dbpass = "***";
// database connection
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);
// new data
$date = date('Y-m-d') ."\n";
$now = time(); $utc_time = $now - intval(date('Z', $now));
$time = date('H:i:s', $now);
$pname = $_POST['pname'];
$pdetails = $_POST['pdetails'];
$pabout = $_POST['pabout'];
$pwebsite = $_POST['pwebsite'];
$pyoutube = $_POST['pyoutube'];
$pfacebook = $_POST['pfacebook'];
$uID = $_POST['uID'];
$id = $_POST['id'];
$seshID = $_SESSION['user']['id'];
$conn->prepare($sql = "UPDATE pages SET pname='$pname', pdetails='$pdetails', pabout='$pabout', pwebsite='$pwebsite', pyoutube='$pyoutube', pfacebook='$pfacebook' WHERE id='$id' AND author_id='$seshID'");
?>

Answer 1

Make sure that you are getting all the data from POST method. For that you can echo all the variables... The basic reason for your script not working is that you are not sending the query to the database.. Use a script like this:
$stmt = $conn->prepare("UPDATE pages SET pname='$pname', pdetails='$pdetails', pabout='$pabout', pwebsite='$pwebsite', pyoutube='$pyoutube', pfacebook='$pfacebook' WHERE id='$id' AND author_id='$seshID'");
$stmt->execute();
