How do I write a php function to show class in navigation menu url using php self

Tags: php,css,navigationbar

Problem :

I'm trying to figure out how to add a css class to a <li> tag in my menu navigation. I'm using a template that gets included on every page of site. In the template is the menu navigation code. I need to set the css class on the <li> for the corresponding active page using PHP_SELF I presume?

Navigation looks like this

Navigation Menu

And this is what it should look like when the page is displayed that corresponds to the page that was clicked in the navigation menu.

Navigation Menu with class="current"

Here is the navigation menu code

<!-- MENU BEGIN -->
<div id="menu">
<ul id="nav">
<li><a href="/">Home</a></li>
<li <?php echo $class_current; ?>><a href="technician-jobs/">Technician</a></li>
<li <?php echo $class_current; ?>><a href="programming-jobs/">Programming</a></li>
<!-- MENU END -->

Here is the PHP function I am trying to create

function classCurrent(){
if(dirname($_SERVER['PHP_SELF']) == true) {
 echo ' class="current"';
else {
 echo '';

 $current = classCurrent();
 return $current;

I know this is possible, I just can't figure it all out yet.

Solution :

So it is really simple actually to do this. All that needs to be done is have a variable set on the active page above the <html> tag preferably.


<?php $currentPage = 'technician';

So now we have this variable set on the technician page above the html tag. Now to call it in the template page on the navigation menu <li> all that needs to be done is the following.

<?php if ($currentPage=="technician") echo " class=\"current\""; ?>

Now just need to repeat this step for each page of the website.

This was also answered here PHP navigation menu

and a real good tutorial on how to do it is here

As a result the navigation code will end up looking something like this

<!-- MENU BEGIN -->
<div id="menu">
<ul id="nav">
<li<?php if ($currentPage=="home") echo " class=\"current\""; ?>><a href="/">Home</a></li>
<li<?php if ($currentPage=="technician") echo " class=\"current\""; ?>><a href="technician-jobs/">Technician</a></li>
<li<?php if ($currentPage=="programming") echo " class=\"current\""; ?>><a href="programming-jobs/">Programming</a></li>
<!-- MENU END -->
