Question

I will try to be as clear as possible because I can’t get anybody to help me around,

I am trying to associate some data from a ‘videos’ table with their respective ID.

Lets say, I have column ID, title, serie, season, episode.

I am getting my data :

    <?
$result = mysql_query("SELECT * FROM videos WHERE serie = '".$row['serie']."' AND season = '".$row['season']."'");
$total_rows = mysql_num_rows($result);
       ?>

(that is in the page where you see the video itself)

So now I can get the number of episodes from a serie and season.

What I’m trying to do is have a link for the next episode, and aa link for the previous one. In the URL I am working with the id, so http://website.com/view/id/‘video id here’/

So how can I get the ID of the following and previous episodes of the same season AND serie?

Help will be much appreciated!

The easiest thing I thought of is

<?=$row['id'] + 1?>
<?=$row['id'] - 1?>

But the thing is that it’s mixed videos, so it wont work 100%

I think you’ve taken my example too literally. I’ll post a complete example in the morning (I’m just replying from my iPhone at the mo). For some reason it wouldn’t let me add a comment to your last reply, so sorry this is as an answer.

[edit] here’s a more complete example:

<?php

$result = mysql_query("SELECT * FROM videos WHERE series='$series' AND season = '$season'");

$last_row = null;
$next_row = null;

$current_id = $_GET['id'];

while($row = mysql_fetch_assoc($result)) {
    if($current_id == $row['id']) {
        $next_row = mysql_fetch_assoc($result);
        break;
    }

    $last_row = $row;
}

if($last_row != null) {
    echo "<a href='?id={$last_row['id']}'>Prev</><br/>\n";
}

if($next_row != null) {
    echo "<a href='?id={$next_row['id']}'>Next</><br/>\n";
}

?>

A few things to note:

• This is untested.
• In your initial example, I didn’t know where you were getting the $row[‘serie’] and $row[‘season’], so in my example, I’ve just used the variables $series and $season. You’ll have to fill these in with what you want the current result set to be filtered by.
• For my example, the URL format uses the GET layout (ie. ?id=).
