    <p>In <code>edit_movie.php</code> it doesn't look like you're actually getting the movie passed view the form. You need something like this in your <code>movie.inc.php</code>:</p> <pre><code>function get_movie_to_edit($id) { $query = "SELECT * FROM movies m INNER JOIN categories c ON m.genre_id = c.genre_id WHERE id = $id"; $result = mysql_query($query); if ( ! $result ){ return false; } else { while ($row = mysql_fetch_assoc($result)){ $return = array('director' =&gt; $row['director'], 'genre' =&gt; $row['genre'], 'release_year' =&gt; $row['release_year'], 'title' =&gt; $row['title'], 'id' =&gt; $row['id']); } return $return; } } </code></pre> <p>And then in edit_movie.php you need to call this function. Something like...</p> <pre><code>if(isset($_GET['edit'])) { $movie = get_movie_to_edit($_GET['edit']); } </code></pre> <p>Of course, as you mentioned, you need to clean up a lot of the code to prevent against injection and check for a scenario where, say, you get to <code>edit_movie.php</code> and the ID ro edit doesn't exist, but this is the basic gist.</p> <p>You would also then edit the values in the form in <code>edit_movie.php</code> to reflect the new array like:</p> <pre><code>&lt;form action="edit_movie.php" method="post"&gt; &lt;input type="hidden" name="id" value="&lt;?php echo $movie['id']; ?&gt;" /&gt; &lt;br&gt; Title:&lt;br&gt; &lt;input type="text" name="title" value="&lt;?php echo $movie['title']; ?&gt;" /&gt; &lt;br&gt; .... the rest of your form inputs &lt;/form&gt; </code></pre> <p><strong>Updated</strong> For the genre radio buttons...</p> <pre><code>&lt;input type="radio" name="genre_id" value="1"&lt;?php if($movie['genre'] == 1) { echo ' checked'; } ?&gt; /&gt;Action&lt;br&gt; &lt;input type="radio" name="genre_id" value="2"&lt;?php if($movie['genre'] == 2) { echo ' checked'; } ?&gt; /&gt;Comedy&lt;br&gt; .... and so on </code></pre>

    1. COHi! Thank you for your comment! So I just tried your code, I think it´s almost the same as I tried before and I get the same error in all the form fields: <br /><b>Notice</b>: Undefined index: title in <b>C:\Program Files (x86)\EasyPHP-12.1\www\test\edit_movie.php</b> on line <b>40</b><br /> Do you know what to do? How can I define the 'title' etc..

    2. COSee my edit. When you build the $return array, make it like: `$return = ...` instead of `$return[] = ...`

    3. COOh jeez!!! It´s working!!! Only thing though. In edit_movie.php how should I write the value for the radio buttons? On title etc its value="<?php echo $movie['id']; but on the radion buttons the value is already set on the genre_id. So it doesn´t work there...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
