INSERT INTO table VALUES - mysql_query to PDO - php

Question

trying to insert values from an old mysql_query using the new PDO and can't seem to get it. Here's the old code that works with the old method:
$query = mysql_query("INSERT INTO videos VALUES ('','$title',time(),'0','$length','','$name','$cat','$reciter','$genre')");
I've tried variations of the following code taken from another question on stack, but nothing that works for me.
$query = "UPDATE people
SET price=?,
contact=?,
fname=?,
lname=?
WHERE id=? AND
username=?";
$stmt = $dbh->prepare($query);
$stmt->bindParam(1, $price);
$stmt->bindParam(2, $contact);
$stmt->bindParam(3, $fname);
$stmt->bindParam(4, $lname);
$stmt->bindParam(5, $id);
$stmt->bindParam(6, $username);
$stmt->execute();
the first value to be inserted is an auto increment value in the db. I am at a loss as to how to write that with the new PDO. Then the third is an attempt at a timestamp. All others are values that exist in the script already.
So this is more along the lines of what I'm looking for.. Its what I have now, but doesn't work.
$sql = "INSERT INTO videos (id, title, timestamp, views, length, image, vid_url, cetegory, reciter, genre)
VALUES (:id, :title, :timestamp, :views, :length, :image, :vid_url, :category, :reciter, :genre)";
$query = $DBH->prepare($sql);
$results = $query->execute(array(
":id" => '',
":title" => $title,
":timestamp" => time(),
":views" => '0',
":length" => $length,
":image" => '',
":vid_url" => $name,
":category" => $cat,
":reciter" => $reciter,
":genre" => $genre
));

Answer 1

If id is an autoincrement, don't pass it to your query. If you specify a value to be inserted to an autoincrement table, sql will attempt to insert that value. so don't include it in the query, let SQL do that.
Secondly, if the third field is a timestamp, set the default to
CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
SQL will update the timestamp automatically on update or insert (if you only want it on insert just put CURRENT_TIMESTAMP. then you also can drop that row.
You can also drop the images row if you aren't inserting anything there either, no point to put something in the query if you're not using it!
Also, the key PDO looks for doesn't have the colon (:) so if your item is :title, the array key will be just 'title'. So, your code should look something like:
$sql = "INSERT INTO videos ( title, views, length,, vid_url, cetegory, reciter, genre)
VALUES (:title, :views, :length, :vid_url, :category, :reciter, :genre)";
$query = $DBH->prepare($sql);
$results = $query->execute(array(
"title" => $title,
"views" => '0',
"length" => $length,
"vid_url" => $name,
"category" => $cat,
"reciter" => $reciter,
"genre" => $genre
));
