if exist else insert PHP - php

Question

I have some problem with my if else statement, but I cant figure out what, since it should work :)
What im trying to do is that IF the video_title already exist in my row then do nothing,
but if the video_title does not exist, insert values to the table.
I have the value marvel.mp4 in my video_title column,
But it still keeps on inserting marvel.mp4 as value on new rows...
Any ideas why its not working?
$query = $dbh->query("SELECT video_title FROM video");
$q = $query->fetch(PDO::FETCH_OBJ);
$video_title = "marvel.mp4";
if($video_title ==$q){
// Do Nothing
}else{
$sql = "INSERT INTO video (video_title, video_cat, video_date) VALUES (:video_title, :video_cat, NOW())";
$query = $dbh->prepare($sql);
$query->execute(array(
':video_title' => $video_title,
':video_cat' => $video_cat
));
}

Answer 1

It should be:
if ($video_title == $q->video_title)
When you use PDO::FETCH_OBJ, each column is a property of the object.
You also need to be more specific in the query, otherwise you're just testing whether the video is the first one returned by the query.
$video_title = "marvel.mp4";
$stmt - $dbh->prepare("SELECT video_title FROM video WHERE video_title = :title");
$stmt->execute(array(':title' => $video_title));
$q = $stmt->fetch(PDO::FETCH_OBJ);

This code will solve your problem. I have just tested and run it and is working.

));
$nosofrows = $result->rowCount();
if ($nosofrows == 1)
//if ($nosofrows ==0)
{
echo '<br><b><font color=red><b></b>Video Title Already exist. Do not insert</font></b><br>';
exit();
}else{
// insert data
$statement = $db->prepare('INSERT INTO video(video_title,video_name)
values
(video_title,video_name)')
$statement->execute(array(
':video_title' => $video_t,
