evhwanabe Posted October 11, 2005 Posted October 11, 2005 First off, let me start by saying I am not an expert in PHP, but I got this work and thought maybe other people could use it. I ran into a problem on my last project where I was using a php include for my navigation bar, No big deal right? But I also wanted to be able to change the class of my active page/link on each page so the button/link looked like it was pressed down. Look here to see what I mean. This is no sweat if you have your nav code on each page, you would just set the class to "active" or whatever and you would be good to go. I wrote this little script to basically check what page I am on, and then set the class active for that page. I now have a php include navbar that knows what page you are currently on and changes the link class accordingly. I am not going to get into the css side of this. I will save that for another time lol. ><? if ($PHP_SELF != '/page1.php') { $page1 = 'none'; } else { $page1 = 'active'; } if ($PHP_SELF != '/page2.php') { $page2 = 'none'; } else { $page2 = 'active'; } if ($PHP_SELF != '/page3.php') { $page3 = 'none'; } else { $page3 = 'active'; } if ($PHP_SELF != '/page4.php') { $page4 = 'none'; } else { $page4 = 'active'; } ?> <ul id="nav"> <li><a href="/page1.php" class="<?echo $page1;?>">page1</a></li> <li><a href="/page2.php" class="<?echo $page2;?>">page2</a></li> <li><a href="/page3.php" class="<?echo $page3;?>">page3</a></li> <li><a href="/page4.php" class="<?echo $page4;?>">page4</a></li> </ul> Like I said, I am not an expert, so if you know of a better way please share.....

owatagal Posted October 12, 2005 Posted October 12, 2005 evhwanabe, I do something very similar with one of my nav menus. The only thing I would suggest is that you could use the ternary operator to tighten up the code. For those who don't know, the ternary operator is a slick shorthand for if-then statements; see for example this tutorial in your case, the whole code snippet could be shortened to: ><?php echo '<ul>'; echo ($PHP_SELF == '/page1.php') ? '<li><a class="active" href="/page1.php">Page One</a></li>' : '<li><a class="none" href="/page1.php">Page One</a></li>'; echo ($PHP_SELF == '/page2.php') ? '<li><a class="active" href="/page2.php">Page Two</a></li>' : '<li><a class="none" href="/page2.php">Page Two</a></li>'; echo ($PHP_SELF == '/page3.php') ? '<li><a class="active" href="/page3.php">Page Three</a></li>' : '<li><a class="none" href="/page3.php">Page Three</a></li>'; echo ($PHP_SELF == '/page4.php') ? '<li><a class="active" href="/page4.php">Page Four</a></li>' : '<li><a class="none" href="/page4.php">Page Four</a></li>'; echo '</ul>'; ?> I've formatted it to make it easier to read, but that's really just six lines of code total. And it even includes the commands to print out the <ul> and each individual <li>, so that doesn't have to be a separate part of your code. For me, it's easier to maintain -- if I need to rename page2.php, all the instances of "page2.php" are right in one area of the code. (Not that I'm a fan of the ternary operator or anything... ok, I am. Just a little bit. But it's such a neat little snippet.) Quote

paul100 Posted January 9, 2006 Posted January 9, 2006 Cool owatagal,Thanks for the tip! This is just what I've been looking for but I cant get it to work as it's my first go with PHP. Can anyone either tell me which bit goes where please? Pa ul Quote
TCH-Don Posted January 9, 2006 Posted January 9, 2006 Welcome to the forums Paul I would save it as menu.php and then include it in place of your current menu. <?php include $_SERVER['DOCUMENT_ROOT']."/menu.php"; ?> of course the page has to be a php page for it to work Quote
surefire Posted January 9, 2006 Posted January 9, 2006 (edited) ><?php echo '<ul>'; $navList = array('One','Two','Three','Four'); foreach($navList as $k=>$v) { $x = $k+1; $class = ($PHP_SELF == '/page'.$x.'.php') ? 'active' : 'none'; echo '<li><a class="'.$class.'" href="/page'.$x.'.php">Page '.$v.'</a></li>'; } echo '</ul>'; ?> It's a little shorter... but more importantly, it's easier to reuse on a new site.

theo Posted February 10, 2009 Posted February 10, 2009 (edited) Does anyone know how you would do this with two active states? i.e. I'm using genres: so film/action is an example. What I think I need to be able to do is detect the (directory) level higher as well as the current level... So if you're on film/action(/index.php) both film and action would be the active states. Is this going to be possible? Cheers, Theo. Edited February 10, 2009 by theo Quote
TCH-Bruce Posted February 10, 2009 Posted February 10, 2009 Welcome to the forums theo Yes, it would be possible but I think you would want to use some content management system (CMS) like Joomla or WordPress to do it. Quote
theo Posted February 10, 2009 Posted February 10, 2009 (edited) Is there a way of extracting (separating out) the information from $PHP_SELF ? Edited February 10, 2009 by theo Quote
theo Posted February 10, 2009 Posted February 10, 2009 Is there a way of extracting (separating out) the information from $PHP_SELF ? Well I've done it using this function: <?php function public_base_directory() { //get public directory structure eg "/top/second/third" $public_directory = dirname($_SERVER['PHP_SELF']); //place each directory into array $directory_array = explode('/', $public_directory); return $directory_array[1]; } ?> It seems to work OK, but will have to see if I run into any problems with it later.
