Make navigation menu buttons highlighted for the current page - php

I have created a navigation menu that loads different "includes" on the same page. I want the menu buttons to stay highlighted for the current page. All the answer I have seen here only deal with navigating to a different page for each link. Is is possible to do it on the same page? Because the navigation bar doesn't actually reload.
<nav class="menu">
<ul>
<li class="menuitem"><a href="?link=1" name="fluidBalance" <?php echo ($_GET['link'] == 1) ? 'class="highlight"' : ''; ?>>Calculated Fluid Balance</a></li>
<li class="menuitem"><a href="?link=2" name="actualFluidBalance" <?php echo ($_GET['link'] == 2) ? 'class="highlight"' : '';?>>Actual Fluid Balance</a></li>
<li class="menuitem"><a href="?link=3" name="graphicalView" <?php echo ($_GET['link'] == 3) ? 'class="highlight"' : ''; ?>>Graphical View</a></li>
</ul>
</nav>
<div class="contentFluidBalance" id="mainSection">
<?php
if(isset($_GET['link'])){
$link=$_GET['link'];
if ($link == '1'){
include 'includes/fluidBalance1.php';
}
if ($link == '2'){
include 'includes/fluidBalance2.php';
}
if ($link == '3'){
include 'includes/fluidBalance5.php';
}
}
?>

You can try this :
<nav class="menu">
<ul>
<li class="menuitem"><a href="?link=1" name="fluidBalance" <?php echo ($_GET['link'] == 1) ? 'class="highlight"' : ''; ?>>Calculated Fluid Balance</a></li>
<li class="menuitem"><a href="?link=2" name="actualFluidBalance" <?php echo ($_GET['link'] == 2) ? 'class="highlight"' : '';?>>Actual Fluid Balance</a></li>
<li class="menuitem"><a href="?link=3" name="graphicalView" <?php echo ($_GET['link'] == 3) ? 'class="highlight"' : ''; ?>>Graphical View</a></li>
</ul>
</nav>
where class="highlight" is the name of the class to highlight the menu.

In the end The following code worked for me:
<nav class="menu">
<ul>
<li<?php if (isset($_GET['link']) && $_GET['link'] == '1') echo 'class="current"'?>>Calculated Fluid Balance</li>
<li<?php if (isset($_GET['link']) && $_GET['link'] == '2') echo ' class="current"'?>>Actual Fluid Balance</li>
<li<?php if (isset($_GET['link']) && $_GET['link'] == '3') echo ' class="current"'?>>Graphical View</li>
</ul>
</nav>
<div class="contentFluidBalance" id="mainSection">
<?php
if(isset($_GET['link'])) {
$link=$_GET['link'];
if ($link == '1'){
include 'includes/fluidBalance1.php';
}
if ($link == '2'){
include 'includes/fluidBalance2.php';
}
if ($link == '3'){
include 'includes/fluidBalance5.php';
}
}
?>
</div>

First, check if the current page is equal to one of your menuitem :
<nav class="menu">
<ul>
<li class="menuitem <?php if (isset($_GET['link']) && $_GET['link'] == '1') : ?>current<?php endif; ?>">Calculated Fluid Balance</li>
<li class="menuitem <?php if (isset($_GET['link']) && $_GET['link'] == '2') : ?>current<?php endif; ?>">Actual Fluid Balance</li>
<li class="menuitem <?php if (isset($_GET['link']) && $_GET['link'] == '3') : ?>current<?php endif; ?>">Graphical View</li>
</ul>
</nav>
<div class="contentFluidBalance" id="mainSection">
<?php
if(isset($_GET['link'])) {
$link=$_GET['link'];
if ($link == '1'){
include 'includes/fluidBalance1.php';
}
if ($link == '2'){
include 'includes/fluidBalance2.php';
}
if ($link == '3'){
include 'includes/fluidBalance3.php';
}
}
?>
</div>
Then, in your CSS, do whatever you want with the current class :
.menuitem.current a {
color:red;
}

How to make active both the header button and the listed button?

First of all, apoligise for the messy title, I could not came up with a better one. You will understand the question better in the code. When I click in Private University I can make that button active, but I either want to make active the button Study Opportunity. Thanks.
<li class="dropdown <?php if(basename($_SERVER['SCRIPT_NAME']) == 'study-opportunity.php'){echo 'active'; }else { echo ''; } ?>">
Study Opportunity<span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'universitetet-me-konkurim.php'){echo 'active'; }else { echo ''; } ?>">Universitetet me Konkurim</li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'private-university.php'){echo 'active'; }else { echo ''; } ?>">Private University</li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'studime-jashte-vendit.php'){echo 'active'; }else { echo ''; } ?>">Studime Jashte Vendit</li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'bursa.php'){echo 'active'; }else { echo ''; } ?>">Bursa Studimi</li>
</ul>
</li>
You have to check all of the links in the dropdown too:
<li class="dropdown <?php if(basename($_SERVER['SCRIPT_NAME']) == 'study-opportunity.php' || basename($_SERVER['SCRIPT_NAME']) == 'universitetet-me-konkurim.php' || basename($_SERVER['SCRIPT_NAME']) == 'private-university.php' || basename($_SERVER['SCRIPT_NAME']) == 'studime-jashte-vendit.php' || basename($_SERVER['SCRIPT_NAME']) == 'bursa.php'){echo 'active'; }else { echo ''; } ?>">
Study Opportunity<span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'universitetet-me-konkurim.php'){echo 'active'; }else { echo ''; } ?>">Universitetet me Konkurim</li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'private-university.php'){echo 'active'; }else { echo ''; } ?>">Private University</li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'studime-jashte-vendit.php'){echo 'active'; }else { echo ''; } ?>">Studime Jashte Vendit</li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'bursa.php'){echo 'active'; }else { echo ''; } ?>">Bursa Studimi</li>
</ul>
</li>

index.php url need to hide from homepage of php website

The website www.indowesterncaterers.com/ has menu in header.php
<ul>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'index.php'){echo 'active'; }else { echo ''; } ?>">Home</li>
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'about-us.php'){echo 'active'; }else { echo ''; } ?>">About US</li>

</ul>
from other pages , like http://www.indowesterncaterers.com/wedding-catering.php
If I click on homepage , the url shows http://www.indowesterncaterers.com/index.php
I want to hide index.php url when clicked from other navigation urls.
The site in core PHP ,
Instead of using
Home
try
Home
Assuming DirectoryIndex is set to index.php, you should be able to use -
<li class="<?php if(basename($_SERVER['SCRIPT_NAME']) == 'index.php'){echo 'active'; }else { echo ''; } ?>">Home</li>

Add class="active" to active page using PHP

Dynamic Header, CSS Class Change To Active USING PHP (dirrectory)
I want the class of the <li> tag to change under the active dirrectory...
now, every guide shows me how to do it when your page equals it, but i want to change
the <li> depending on what dirrectory im on
for example:
if say im on http://example.com/RESOURCES/code/opensource, or http://example.com/RESOURCES/images/clipart i want the "RESOURCES" ^^ <li> to be 'class="active"' while the rest display 'class="noactive"'
or if im on http://example.com/tutorials/css/flawless-dropdown-menu I want the "tutorials" <li> to be 'class="active"' while the rest are 'class="noactive"'
URL Setup:
This is my example of how my url's are displayed...
http://example.com/tutorials/css/flawless-dropdown-menu
^^That URL is the page of a tutorial....under the "tutorials" directory, than under the "CSS" category directory, than the page title (all of these directories are not real and are rewrites from .htaccess) [irrelevant]
Navigation Setup:
<ul id="mainnav">
<li class="noactive">Home</li>
<li class="active">Tutorials</li>
<li class="noactive">Resources</li>
<li class="noactive">Library</li>
<li class="noactive">Our Projects</li>
<li class="noactive">Community</li>
</ul>
Figured out the ANSWER...I was over thinking it.
HTML
<ul id="mainnav">
<li class="<?php if ($first_part=="") {echo "active"; } else {echo "noactive";}?>">Home</li>
<li class="<?php if ($first_part=="tutorials") {echo "active"; } else {echo "noactive";}?>">Tutorials</li>
<li class="<?php if ($first_part=="resources") {echo "active"; } else {echo "noactive";}?>">Resources</li>
<li class="<?php if ($first_part=="library") {echo "active"; } else {echo "noactive";}?>">Library</li>
<li class="<?php if ($first_part=="our-projects") {echo "active"; } else {echo "noactive";}?>">Our Projects</li>
<li class="<?php if ($first_part=="community") {echo "active"; } else {echo "noactive";}?>">Community</li>
</ul>
PHP
<?php
$directoryURI = $_SERVER['REQUEST_URI'];
$path = parse_url($directoryURI, PHP_URL_PATH);
$components = explode('/', $path);
$first_part = $components[1];
?>
header.php
$activePage = basename($_SERVER['PHP_SELF'], ".php");
nav.php
<ul>
<li class="<?= ($activePage == 'index') ? 'active':''; ?>">Home</li>
<li class="<?= ($activePage == 'tutorials') ? 'active':''; ?>">Tutorials</li>
...
Through PHP you can try -
<?php
// gets the current URI, remove the left / and then everything after the / on the right
$directory = explode('/',ltrim($_SERVER['REQUEST_URI'],'/'));
// loop through each directory, check against the known directories, and add class
$directories = array("index", "tutorials","resources","library","our-projects","community"); // set home as 'index', but can be changed based of the home uri
foreach ($directories as $folder){
$active[$folder] = ($directory[0] == $folder)? "active":"noactive";
}
?>
<ul>
<li class="<?php echo $active['index']?>">Home</li>
<li class="<?php echo $active['tutorials']?>">Tutorials</li>
<li class="<?php echo $active['resources']?>">Resources</li>
<li class="<?php echo $active['library']?>">Library</li>
<li class="<?php echo $active['our-projects']?>">Our Projects</li>
<li class="<?php echo $active['community']?>">Community</li>
</ul>
Maybe this helps you:
$(document).ready(function()
{
var parts = document.URL.split("/");
// [http:, empty, your domain, firstfolder]
var firstFolder = parts[3];
$("#mainnav li").attr("class", "noactive");
$("#mainnav a[href='/" + firstFolder + "/']").parent().attr("class", "active");
});
It's probably easier to do with jQuery but this works:
$url='http://example.com/tutorials/css/flawless-dropdown-menu';//pass the current url here instead of a static string.
$segments = explode ("/",$url);
$menuItems=array('Tutorials','Resources', 'Library', 'Our-Projects','Community');
$menu=array();
foreach ($menuItems as $menuItem) {
if($segments[3]==strtolower($menuItem)){
$menu[]=('<li class="active">'.str_replace("-"," ",$menuItem).'</li>');
} else {
$menu[]=('<li class="no-active">'.str_replace("-"," ",$menuItem).'</li>');
}
}
foreach ($menu as $item) {
echo $item.'<br />';
}
if you use mysql_fetch defined your row for menu title.
if we take your menu title is MENU in mysql database and you have to put in
(Home,tutorials,library,resources,our-projects,community)
<?php
//connect your data bass
include(connection.php');
//get your from ID like www.google?id=1
$id = $_GET['id'];
$query = "select * from pages where id='$id'";
$query1 = mysql_query($query);
while($row= mysql_fetch_array($query1))
{
?>
<html>
<?php $active= $row['MENU'];?>
<ul>
<li class="<?php if($active=='Home'){echo 'active';}else{echo'noactive';}?>">Home</li>
<li class="<?php if($active=='tutorials'){echo 'active';}else{echo'noactive';}?>">Tutorials</li>
<li class="<?php if($active=='resources'){echo 'active';}else{echo'noactive';}?>">Resources</li>
<li class="<?php if($active=='library'){echo 'active';}else{echo'noactive';}?>">Library</li>
<li class="<?php if($active=='our-projects'){echo 'active';}else{echo'noactive';}?>">Our Projects</li>
<li class="<?php if($active=='community'){echo 'active';}else{echo'noactive';}?>">Community</li>
</ul>
</html>
<?php };?>
This answer will apply if all your pages have a php extension and you want a long messy way. I put the code below on top of every php page giving each page an ID which means all pages will have an ID which is tiresome and boring and hard to track.
<?php $page = 1; ?>
Now in my header or navigation I used the code below to put the active class. You can also put an else if you want something else.
<nav id="navbar" class="navbar">
<ul>
<li class="<?php if($page == 1){ echo "active"; } ?>"><a class="url" href="index.php">Index</a></li>
<li class="<?php if($page == 2){ echo "active"; } ?>"><a class="url" href="single-post.php">Information</a></li>
<li class="<?php if($page == 3){ echo "active"; } ?>"><a class="url" href="single-post.php">Wanted</a></li>
<li class="<?php if($page == 4){ echo "active"; } ?>"><a class="url" href="single-post.php">Workshop</a></li>
<li class="<?php if($page == 5){ echo "active"; } ?>"><a class="url" href="gallery.php">Gallery</a></li>
<li class="<?php if($page == 6){ echo "active"; } ?>"><a class="url" href="featured.php">Featured</a></li>
<li class="<?php if($page == 7){ echo "active"; } ?>"><a class="url" href="contact.php">Contact Us</a></li>
</ul>
</nav>
"includes/header.php" - This goes in Top of the File
<?php
$activePage = basename($_SERVER['PHP_SELF']);
$index="";
$nosotros="";
$cursos="";
$contacto="";
switch ($activePage) {
case 'index.php':
$index=' class="current"';
break;
case 'nosotros.php':
$nosotros=' class="current"';
break;
case 'cursos.php':
$cursos=' class="current"';
break;
case 'contacto.php':
$contacto=' class="current"';
break;
default:
break;
}
?>
and this goes on the nav section
<ul>
<?php
echo '<li'.$index.'><div>Inicio</div></li>';
echo '<li'.$nosotros.'><div>Nosotros</div></li>';
echo '<li'.$cursos.'><div>Cursos</div></li>';
echo '<li><div>Academia</div></li>';
echo '<li><div>Tienda</div></li>';
echo '<li'.$contacto.'><div>Contacto</div></li>';
?>
</ul>
Try the following:
<ul class="sub-menu">
<div class="h-10"></div>
<li class="<?php if ($your_variable=="test") {echo "active"; }
else{echo"noactive";}?>">
Test
</li>
<li class="<?php if ($your_variable=="test2") {echo "active";
} else {echo"noactive";}?>">
<a href="test2.php" >Test2</a>
</li>
<li class="<?php if ($your_variable=="test3") {echo
"active"; } else {echo "noactive";}?>">
Test3
</li>
</ul>
**strong PHP text**
<?php
$directoryURI = $_SERVER['REQUEST_URI'];
$path = parse_url($directoryURI, PHP_URL_PATH);
$components = explode('/', $path);
$your_variable = basename($_SERVER['PHP_SELF'], ".php");
?>
Here we can do a simple thing also :
<li class="page-scroll <?php if(basename($_SERVER['PHP_SELF'])=="aboutus.php"){echo "active";} ?>">About us</li>
Here is another take using PHP:
<ul class="navbar-nav">
<?php
// Defines all pages in navigation
$pages = array(
'Home' => 'index.php',
'Products' => 'products.php',
'Services' => 'services.php',
'Contact' => 'contact.php',
'About' => 'about.php'
);
// Gets active page URL
$active = basename($_SERVER['PHP_SELF']);
// Loops through all pages
foreach ($pages as $title => $url) {
// Checks if active url is matched and adds active CSS class
if ($active === $url) {
echo '<li>'.$title.'</li>';
}
// Prints out default style for remaining links
else {
echo '<li>'.$title.'</li>';
}
}
?>
</ul>
$getUrl = $_SERVER['REQUEST_URL']; -> www.example.com/home.php
$getFileName = explode('/',$getUrl);
The result of $getFileName Will Be In Array ->[" ","home.php"]
$result = $getFileName[2]; //home.php
<li class="<?php if ($result=='' || $result == 'index.php') {echo 'active'; }?>"><a href='#'>Home</a></li>
<li class="<?php if ($result=='about.php') {echo 'active'; }?>"><a href='#'>About Us</a></li>
<li class="<?php if ($result=='contact.php') {echo 'active'; }?>"><a href='#'>Contact Us</a></li>
You can use str_replace for this.
$path = $_SERVER['REQUEST_URI'];
$active = str_replace('/','', $path);
<ul>
<li class="nav-item <?php if($active == '' || $active == 'index.php'){echo 'active';}?>">
<a class="nav-link" href="index.php">HOME</a>
</li>
<li class="nav-item <?php if($active == 'about.php'){echo 'active';}?>">
<a class="nav-link" href="about.php">ABOUT US</a>
</li>
</ul>
<?php $request_uri= $_SERVER['REQUEST_URI'];?>
<ul>
<li class="<?php if((strpos($request_uri,"index.html")!==false) || $request_uri=="" || $request_uri=="/"){echo "selected";}?>">Home</li>
<li class="<?php if((strpos($request_uri,"service")!==false)){echo "selected";}?>">Services </li>
<li class="<?php if((strpos($request_uri,"product")!==false)){echo "selected";}?>">Products</li>
<li class="<?php if((strpos($request_uri,"blog")!==false)){echo "selected";}?>">Blog</li>
<li class="<?php if((strpos($request_uri,"question")!==false)){echo "selected";}?>">Ques & Ans</li>
<li class="<?php if((strpos($request_uri,"career")!==false)){echo "selected";}?>">Career</li>
<li class="<?php if((strpos($request_uri,"about-us")!==false)){echo "selected";}?>">About</li>
</ul>

php check if link has been clicked

Hi I'm a novice at php could some please help. I'm making a website it has a menu, I need it so that if a link like "link1" is clicked page1.php will load into the the mainSection div and if link2 is clicked page2.php will load in mainSection etc. so all the pages: page1, page2, page3 etc will load into this single page depending on what link has been clicked. Is this possible I don't know where to start. Thanks
<body>
<?php
<ul>
<li>link 1</li>
<li>link 2</li>
<li>link 3</li>
<li>link 4</li>
</ul>
?>
<div id="mainSection">
<?php
if (link1 == true){
include 'page1.php';
}
if (link2 == true){
include 'page2.php';
}
if (link3 == true){
include 'page3.php';
}
if (link4 == true){
include 'page4.php';
}
?>
</div>
</body>
Here's something you can start with
<body>
<ul>
<li>link 1</li>
<li>link 2</li>
<li>link 3</li>
<li>link 4</li>
</ul>
<div id="mainSection">
<?php
$link=$_GET['link'];
if ($link == '1'){
include 'page1.php';
}
if ($link == '2'){
include 'page2.php';
}
if ($link == '3'){
include 'page3.php';
}
if ($link == '4'){
include 'page4.php';
}
?>
</div>
</body>
In addition to majid's code you have to check if the link has been set or else it throws an error of undefined $link.
link 1
link 2
link 3
link 4
<div id="mainSection">
<?php
if(isset($_GET['link'])){
$link=$_GET['link'];
if ($link == '1'){
include 'page1.php';
}
if ($link == '2'){
include 'page2.php';
}
if ($link == '3'){
include 'page3.php';
}
if ($link == '4'){
include 'page4.php';
}
} ?>
</div>
</body>
Change the format of your links to:
link 1...
and then change your PHP to:
<?php
if ($_SERVER['QUERY_STRING'] == 1){
include 'page1.php';
}
if ($_SERVER['QUERY_STRING'] == 2){
include 'page2.php';
}
if ($_SERVER['QUERY_STRING'] == 3){
include 'page3.php';
}
if ($_SERVER['QUERY_STRING'] == 4){
include 'page4.php';
}
?>

PHP set active link on page using includes

So I have searched SO for an hour trying to find the answer, and also tried various methods, including this
I am trying to include my pages, along with the navigation. But on the correct page, I need the list-item to have a class of active. The navigation is in header.php and currently looks like this:
<nav>
<ul>
<li class="active"> Home </li>
<li> Apps </li>
<li> Forums </li>
</ul>
</nav>
First, I have no idea if JS(jQuery) would be better, or if PHP was to be better. Both wouldn't matter if it works.
Also I am a bit new with PHP and trying to learn.
What would be the easiest (hopefully) method to use? So I don't have to change a lot of code just to give a nav class="active"
Asumming you have a $page variable (which contains the name of the page you are currently on):
<nav>
<ul>
<li class="<?php echo ($page == "home" ? "active" : "")?>"> Home </li>
<li class="<?php echo ($page == "apps" ? "active" : "")?>"> Apps </li>
<li class="<?php echo ($page == "forums" ? "active" : "")?>"> Forums </li>
</ul>
</nav>
Here is a simple way where you do not need to add any other variable
<li class="<?php echo ($_SERVER['PHP_SELF'] == "/index.php" ? "active" : "");?>">
Start
</li>
<li class="<?php echo ($_SERVER['PHP_SELF'] == "/about.php" ? "active" : "");?>">
About
</li>
<li class="<?php echo ($_SERVER['PHP_SELF'] == "/practices.php" ? "active" : "");?>">
Practices
</li>
Add basename function before $_SERVER. I hope it will work.
echo (basename($_SERVER['PHP_SELF']) == 'yourPageName' ?'active' : " ");
At page header use:
<?php $loc = this.location; ?>
Then at every link add:
<?php(this.href == $loc) ? echo 'class="active"' : '' ?>
define variable $page="index.php" in index.php page and for other pages change the variable value according to the page name
<li class="<?php echo ($page == "index.php" ? "active" : "")?>">
Home
</li>
<li class="<?php echo ($page == "about.php" ? "active" : "")?>">
About
</li>
<li class="<?php echo ($page == "service.php" ? "active" : "")?>">
Services
</li>
<li class="<?php echo ($page == "contact.php" ? "active" : "")?>">
Contact
</li>
$page_url = $_SERVER['QUERY_STRING'];
$s = explode("&",$page_url);
//print $s[0];
$page = $s[0];
function createTopNav($page)
{
$pages = array(
array(
'name'=>'Feeder',
'link'=>'page=feeder'
),
array(
'name'=>'Services',
'link'=>'page=services'
),
array(
'name'=>'Development',
'link'=>'page=development'
),
array(
'name'=>'Design',
'link'=>'page=design'
),
);
$res = "";
foreach($pages as $key=>$val)
{
if($val['link']==$page)
{
$res.= "<a class=\"active\" href=\"?"
.$val['link'].
"\">"
.$val['name'].
"</a>";
}
else
{
$res.= "<a class=\"\" href=\"?"
.$val['link'].
"\" >"
.$val['name'].
"</a>";
}
}
$res.="";
return $res;
}
echo createTopNav($page);
if you are using query string exmaple.com?page_id=Apps to pass page id than with php you can
approach this thing
$page_id = $_REQUEST['page_id'];
<ul>
<li class="<?php echo ($page_id == "Home" ? "active" : "");?>">
Home
</li>
<li class="<?php echo ($page_id == "Apps" ? "active" : "");?>">
Apps
</li>
<li class="<?php echo ($page_id == "Forums" ? "active" : ""); ?>">
Forums
</li>
</ul>
If you don't want to use jQuery or PHP - can do next:
Give ID or different CLASS to each <li> element in "your-include-nav.php".
Define the "active" style with CSS in <head> section, on each page.
Add basename function. Then it will work i hope.
