I am having difficulties figuring out how enter retrieved data into a
dropdown box for editing. Here's a snippet:
...snip
<select name="categoriesIN[]" multiple size="8">
<option value="1">Civilization</option>
<option value="2">Monuments, Temples & Tombs</option>
<option value="3">Pharaohs and Queens</option>... snip
As I understand it, I need to put an array ( $categoriesIN[] ) somewhere
in the above code... or do I need to insert a series of value "selected"
fields for the values?
The closest thing to what I need, seems to be in this post:

But it doesn't appear too inviting... not sure if they ever got it to
work...
Think about it. A Select control returns *one* value and not an
array. As such you don't need to provide an array to collect a single
value.
Here's the solution:
HTML
<select name="categories" >
<option value="1">Civilization</option>
<option value="2">Monuments, Temples & Tombs</option>
<option value="3">Pharaohs and Queens</option>
</select>
PHP
$category = $_POST['categories'];
The variable $category will contain 1, 2, or 3 after a post form submit.
Try it.
The reference/link you cite above is for a dynamic select control
that incorporates javascript to populate the second select control.
It's not a simple select.
If you are looking to understand what basic html does, try this:

I often use this site to refresh my failing memory about html stuff.
