Another Dynamic Content question

I know this topic has been talked about many times but I searched the forums for hours and can't find a solution (another newbie). I want to build a menu with 6 links and when you click on the link, the information below the menu in a lower row gets updated (pulled from another php or html file)....that's it....I know it's simple but if you could point me in the right direction I would greatly appreciated. :bemused: :bemused:

Do you mean something like this?

for ($i = 1; $i <= 6; $i++) {
    echo '<a href="' . $_SERVER['PHP_SELF'] . '?link_number=' . $i . '">' .
         'Menu display line ' . $i . '</a><br />';
}

if (isset($_GET['link_number'])) {
     include 'another_php_or_html.file_' . $_GET['link_number'];
}

Yes, something like that, but how do I specify where the links point to
e.g. link one should point to presentation1.html and link2 should point to news.html

Installer

I did it that way just to give you the idea. You can adapt it like so:

echo '<a href="' . $_SERVER['PHP_SELF'] . '?link="presentation1.html">' .
    'Menu display line 1</a><br />';
echo '<a href="' . $_SERVER['PHP_SELF'] . '?link="news.html">' .
    'Menu display line 2</a><br />';
// etc.

if (isset($_GET['link'])) {
    include $_GET['link'];
}

I understand...thanks, but I still get a warning message

Warning: main() [function.include]: Failed opening "for inclusion ...

Is that on my server end or something else...sorry for any inconvenience.

Installer

Yeah, sorry, there's an extra quote mark in there (after "?link=").

To make it easier to maintain/modify you could do it like this:

$links = array('presentation1.html', 'news.html', 'morenews.html',
               'presentation2.html', 'etc.html', 'etc2.html');
for ($i = 0; $i < count($links); $i++) {
    echo '<a href="' . $_SERVER['PHP_SELF'] . '?link=' . $links[$i] . '">' .
         'Menu display line ' . $i . '</a><br />';
}

if (isset($_GET['link'])) {
    include $_GET['link'];
}

Awesome!!! Works like a charm.....thanks again for everything. 😃

Installer

Glad to help.

But try this (a much better example):

$links = array('Presentation 1' => 'presentation1.html', 
               'News'           => 'news.html', 
               'More News'      => 'morenews.html',
               'Presentation 2' => 'presentation2.html', 
               'Etc.'           => 'etc.html', 
               'Etc. 2'         => 'etc2.html');
foreach ($links as $key => $value) {
    echo '<a href="' . $_SERVER['PHP_SELF'] . '?link=' . $value . '">' .
         $key . '</a><br />';
}

if (isset($_GET['link'])) {
    include $_GET['link'];
}

I agree, much better because now I could specify different images for different links...I started doing this already my way, but your way is much better...thanks again.
