Dynamic PHP Navigation Menu Show Current page CSS

[shortysbest]

I have a php website that i write the navigation and everything in dynamically to each page and i am trying to get it to show the current page you are on (change the css class of the current page link) but i havent been able to figure out how to do this. I would appreciate some help with this. I have tried about everything but im not sure if im just making a tiny error or what is up.

 

Menu Code that is written in dynamically(file named navigation.php)::

 

<li><a href="sw.php?page=home">Home</a></li>

<li><a href="sw.php?page=timeline">Timeline</a></li>

<li><a href="sw.php?page=countries">Countries</a></li>

<li><a href="sw.php?page=photos">Photos</a></li>

<li><a href="sw.php?page=facts">Facts</a></li>

<li><a href="sw.php?page=summary">Summary</a></li>

<li><a href="sw.php?page=memorial">Memorial</a></li>

<li><a href="sw.php?page=aftermath">Aftermath</a></li>

 

 

Menu code that is written dynamically to every page:

 

<ul id="navmenu">

<?php include("navigation.php"); ?>

</ul>

Is this what you're looking for?

 

<li><a<?php echo (($current_page == 'sw.php?page=home') ? ' class="current_page"' : ''); ?> href="sw.php?page=home">Home</a></li>
<li><a<?php echo (($current_page == 'sw.php?page=timeline') ? ' class="current_page"' : ''); ?>  href="sw.php?page=timeline">Timeline</a></li>

 

Etc.

Etc.

 

I put my menu all together with it and it comes back with an error.

 

This i sthe code:

<li><a<?php echo (($current_page == 'sw.php?page=home') ? ' class="current_page"' : ''); ?> href="sw.php?page=home">Home</a></li>
<li><a<?php echo (($current_page == 'sw.php?page=timeline') ? ' class="current_page"' : ''); ?>  href="sw.php?page=timeline">Timeline</a></li>
<li><a<?php echo (($current_page == 'sw.php?page=countries') ? ' class="current_page"' : ''); ?> href="sw.php?page=countries">Countries</a></li>
<li><a<?php echo (($current_page == 'sw.php?page=photos') ? ' class="current_page"' : ''); ?>  href="sw.php?page=photos">Photos</a></li>
<li><a<?php echo (($current_page == 'sw.php?page=facts') ? ' class="current_page"' : ''); ?> href="sw.php?page=facts">Facts</a></li>
<li><a<?php echo (($current_page == 'sw.php?page=summary') ? ' class="current_page"' : ''); ?>  href="sw.php?page=summary">Summary</a></li>
<li><a<?php echo (($current_page == 'sw.php?page=memorial') ? ' class="current_page"' : ''); ?> href="sw.php?page=memorial">Memorial</a></li>
<li><a<?php echo (($current_page == 'sw.php?page=aftermath') ? ' class="current_page"' : ''); ?>  href="sw.php?page=aftermath">Aftermath</a></li>

 

 

And for each link it comes back with the error that there is an undefined variable

Actually, the double = signs caused the error, removing those fixed the error, and the links work.. however the function of changing class to current page doesnt work..

You have to define $current_page yourself. There's quite a few different ways to do this, and it will depend on what is most efficient for you. One method if executed from sw.php would be:

 

$current_file = basename(__FILE__);
$key = NULL;
$value = NULL;
$get_string = '';
$start = true;
foreach ($_GET as $key => $value) {
    if ($start) {
        $get_string .= '?';
    }
    else {
        $get_string .= '&';
    $get_string .= $key.'='.$value;
}
$current_page = $current_file.$get_string;

The double equal needs to be in there, = is an assign operator that will always be true when assigning a string to a variable. You should not change the ==.

I'm not having much luck with the code you provided me. lol. sorry im a bit new to php.

[ialsoagree]

In my haste, I forgot a small detail, apologies, try this instead:

 

$current_file = basename(__FILE__);

$key = NULL;

$value = NULL;

$get_string = '';

$start = TRUE;

foreach ($_GET as $key => $value) {

    if ($start) {

        $get_string .= '?';

        $start = FALSE;

    }

    else

        $get_string .= '&';

    $get_string .= $key.'='.$value;

}

$current_page = $current_file.$get_string;

Well that code doesn't bring back an error now. So thats good i guess, however it's not changing the class of the current page menu button. I put the code in the header.php page which dynamically writes it to all the other page, it should work shouldn't it?

No, as I indicated this script must be in the sw.php file (and any other file that the user would see in their browser's navigation bar that needs this functionality). Sorry if I didn't emphasize that more clearly.
