<?php

$dbuser = "root";
$dbpass = "pass";
// database connection
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);
// new data
$name = 'name';
$mime = 'mime';
$data = 'data';
$size = 'size';
$description = 'description';
$created = 'created';
$url = 'url';
// query
$sql = "INSERT INTO videos (name,mime,data,size,description,created,url) VALUES (:name,:mime,:data,:size,:description,:created,:url)";
$q = $conn->prepare($sql);
$q->execute(array(':name'=>$name,

I'm not so good with PDO, I can get videos to upload to my db, but I can't take in a name or anything. It just shows: name, description, size is 0 and etc. I've watched a few tutorials, but none of them show how to add it by what the user names it or describes it as, only what they put into the values goes to the database. I've also searched around on here and many other websites, but no luck.
