PHP Includes

Hi, I've implemented the multi-page article script to display pages from a course directory, however I ma having a real problem working out how to include the full article on my index page.
Here's the code on the index page to switch includes:

<?
switch ($page) {

case "fullarticle":
include('??what goes here????');
break;

etc. ?>

I get the article summaries (showarticles.php) to include on the page ok:

<? include('course_dir/showarticles.php'); ?>

but I cannot get the code right so that clicking on the "Read More" link will then include the full article on the index page. What do I need to do to make the following line of code include the full article as an include file???

<a href="ccs/course_dir/fullarticle.php?articleId=<?php echo $row["articleId"]; ?>">Read More...</a>

Any help would be appreciated. I've spent the last three days tinkering to get it to work, so far without success.

Thanks.

Are you saving your articles on a database? If you are, you shouldn't need the include function.

With de DB model you could do something like this:

if ($_GET['showFull'])
{
print $row['articleContent'];
//shows all
}
else
{
print substr($row['articleContent'],0,500);
// to get the first 500 characters
print "<BR>";
print "<a href=\"article.php?articleId=" . $row["articleId"] . "&showFull=1\">Read More...</a>";

}

And this:
<a href="articles.php?articleId=1&showFull=1">My Article</a>
will return the whole article.

I don't know, may be I am wrong with the example, so try to send me something more about what you are doing.
