I am trying to make a dynamic header in which header link classes update automatically when the page changes. so, like if the user in on index then HOME on header shows in red and if he is on folio page then folio shows in red and so on.
my code.
<?php
switch(basename($_SERVER['PHP_SELF'])){
case "index.php":
$index_hover = "act-link";
break;
case "portfolio.php":
$folio_hover = "act-link";
break;
}
?>
<style>
.act-link {color: red}
</style>
<div class="nav-holder">
Home
Folio
</div>
This code works as expected but the issues say I have 30 links in the header then it's not handy. so I want to make it dynamic so that it detects the page and update as per the need.
Thanks
From your question i think you want to add custom class in navigation menu associated with page
You can do it using php and javascript as well
Using PHP
<?php
function addActiveClass($page){
$url_array = explode('/', $_SERVER['REQUEST_URI']) ;
$url = end($url_array);
if($page == $url){
echo 'act-link'; //class name in css
}
}
?>
<ul>
<li><a class="<?php addActiveClass('home.php');?>" href="http://localhost/Home.php">Home</a></li>
<li><a class="<?php addActiveClass('aboutus.php');?>" href="http://localhost/aboutus.php">About us</a></li>
<li><a class="<?php addActiveClass('contactus.php');?>" href="http://localhost/contactus.php">Contact us</a></li>
</ul>
Here i have added function on every anchor tag addActiveClass which adds class 'act-link' depending on argument passed
Using javascript(jquery)
$(document).ready(function() {
var pathname = window.location.pathname;
$('ul > li > a[href="'+pathname+'"]').parent().addClass('act-link');
})
<ul class="nav">
<li>Home</li>
<li>About us</li>
<li>Contact us</li>
</ul>
I have used jquery here if you want you can write code is core js as well
let me know if there is confusion
Please, I'm new to PHP and I'm building a subscription-based ecommerce site. I've been able to customize the pages such that they look different based on who's browsing what, but I'd like to take the Renew Account off the admin page since they don't have to subscribe.
I've been struggling all day. Please, could someone show me how it could be achieved?
Below is the snippet:
<?php // Show the user info or the login form:
if (isset($_SESSION['user_id'])) {
// Show basic user options:
echo '<div class="title">
<h4>Manage Your Account</h4>
</div>
<ul>
<li>Renew Account</li>
<li>Change Password</li>
<li>Favorites</li>
<li>History</li>
<li>Recommendations</li>
<li>Logout</li>
</ul>
';
// Show admin options, if appropriate:
if (isset($_SESSION['user_admin'])) {
echo '<div class="title">
<h4>Administration</h4>
</div>
<ul>
<li>Add Page</li>
<li>Add PDF</li>
<li>Blah</li>
</ul>
';
}
} else { // Show the login form:
require ('login_form.inc.php');
}
?>
What you could do is to first check if the user admin session is set, to which I added the same conditional value for in the first conditional statement.
If it is set, then assign an empty value for what I named as $renew, with an else{} with the value that I removed from your existing <li></li>.
The first two session arrays here are only representational values of course.
I concatenated the '.$renew.' variable in the menu.
Note: Make sure that the session was started using session_start() inside all pages using sessions; that is not known.
$_SESSION['user_id'] = 123;
$_SESSION['user_admin'] = "john";
if (isset($_SESSION['user_admin'])) {
$renew = '';
} else {
$renew = '<li>Renew Account</li>';
}
if (isset($_SESSION['user_id'])) {
// Show basic user options:
echo '<div class="title">
<h4>Manage Your Account</h4>
</div>
<ul>
'.$renew.'
<li>Change Password</li>
<li>Favorites</li>
<li>History</li>
<li>Recommendations</li>
<li>Logout</li>
</ul>
';
// Show admin options, if appropriate:
if (isset($_SESSION['user_admin'])) {
echo '<div class="title">
<h4>Administration</h4>
</div>
<ul>
<li>Add Page</li>
<li>Add PDF</li>
<li>Blah</li>
</ul>
';
}
}
Try..
If(!isset($_SESSION['user_admin'])) {echo '<li>Renew Account</li>'; }
This way if it the session variable for admin is set the echo won't occur.
This might be very easy for some but I've tried various ways to get it to work but to no avail.
Here's a brief;
I have one page, I have links in this page that when clicked load other pages but display them in the same page.
<section class="posts-header">
<div class="col span-3-of-3">
<ul class="posts-nav" id="navigation">
<li>View Posts</li>
<li>View Posts</li>
<li>Create Post</li>
</ul>
</div>
</section>
The above code shows links that when clicked, pass a variable using $_GET to the switch statement below;
if(isset($_GET['source'])) {
$source = $_GET['source'];}
switch($source) {
case 'view_posts';
include "php/blog_posts_view.php";
break;
case 'view_all_posts';
include "php/blog_posts_reviewer.php";
break;
case 'add_posts';
include "php/blog_posts_addform.php";
break;
case 'edit_posts';
include "php/blog_posts_editform.php";
break;
default:
include "php/blog_posts_view.php";
break;}
How can I highlight the current page? using html, js, css3 or all.
Thanks.
You can just define an active class in CSS, which describes the style of an active link. For example, a very simple style:
.active {
color: red;
}
Then you have to modify your menu:
<section class="posts-header">
<div class="col span-3-of-3">
<ul class="posts-nav" id="navigation">
<li><a href="blog_admin_posts.php?source=view_all_posts"<?=$_GET['source'] == "view_all_posts" ? " class=\"active\"" : ""; ?>>View Posts</a></li>
<li><a href="blog_admin_posts.php?source=view_posts"<?=$_GET['source'] == "view_posts" ? " class=\"active\"" : ""; ?>>View Posts</a></li>
<li><a href="blog_admin_posts.php?source=add_posts"<?=$_GET['source'] == "add_posts" ? " class=\"active\"" : ""; ?>>Create Post</a></li>
</ul>
</div>
</section>
The active menu link text should now be displayed in red.
maybe you will find this very helpful, it adds your class to the current page and allows to add more links to your page by simply adding to the array.
<?php
$page = isset($_GET['page']) ? $_GET['page']: ' ';
$pages = ['view_all_posts','view_posts','add_posts'];
$active = '';
if (in_array($page,$pages)){
$active = 'active';
}
?>
Then modify your menu:
<section class="posts-header">
<div class="col span-3-of-3">
<ul class="posts-nav" id="navigation">
<?php foreach ($pages as $key => $value) : ?>
<li>
<?=$value?>
</li>
<?php endforeach;?>
</ul>
</div>
</section>
You can get the current page name using this:
$pageName = $_GET["source"];
And then, for every list item, you could do something like this:
<li class="<?= ($pageName === 'firstPageName') ? 'active' : '' ?>">...</li>
Of course, you'll need to style the class .active or how ever you would like to name it.
Hi I have a menu on my site on each page, I want to put it in it's own menu.php file but i'm not sure how to set the class="active" for whatever page i'm on.
Here is my code: please help me
menu.php:
<li class=" has-sub">
<a class="" href="javascript:;"><i class=" icon-time"></i> Zeiten<span class="arrow"></span></a>
<ul class="sub">
<li><a class="" href="offnungszeiten.php">Öffnungszeiten</a></li>
<li><a class="" href="sauna.php">Sauna</a></li>
<li><a class="" href="frauensauna.php">Frauensauna</a></li>
<li class=""><a class="" href="custom.php">Beauty Lounge</a></li>
<li><a class="" href="feiertage.php">Feiertage</a></li>
</ul>
</li>
this method gets the current page using php which will pass a word in this case active and places it inside the class parameter to set the page active.
<?php
function active($currect_page){
$url_array = explode('/', $_SERVER['REQUEST_URI']) ;
$url = end($url_array);
if($currect_page == $url){
echo 'active'; //class name in css
}
}
?>
<ul>
<li><a class="<?php active('page1.php');?>" href="http://localhost/page1.php">page1</a></li>
<li><a class="<?php active('page2.php');?>" href="http://localhost/page2.php">page2</a></li>
<li><a class="<?php active('page3.php');?>" href="http://localhost/page3.php">page3</a></li>
<li><a class="<?php active('page4.php');?>" href="http://localhost/page4.php">page4</a></li>
</ul>
It would be easier if you would build an array of pages in your script and passed it to the view file along with the currently active page:
//index.php or controller
$pages = array();
$pages["offnungszeiten.php"] = "Öffnungszeiten";
$pages["sauna.php"] = "Sauna";
$pages["frauensauna.php"] = "Frauensauna";
$pages["custom.php"] = "Beauty Lounge";
$pages["feiertage.php"] = "Feiertage";
$activePage = "offnungszeiten.php";
//menu.php
<?php foreach($pages as $url=>$title):?>
<li>
<a <?php if($url === $activePage):?>class="active"<?php endif;?> href="<?php echo $url;?>">
<?php echo $title;?>
</a>
</li>
<?php endforeach;?>
With a templating engine like Smarty your menu.php would look even nicer:
//menu.php
{foreach $pages as $url=>$title}
<li>
<a {if $url === $activePage}class="active"{/if} href="{$url}">
{$title}
</a>
</li>
{/foreach}
Create a variable in each of your php file like :
$activePage = "sauna"; (different for each page)
then check that variable in your html page like this
<?php if ($activePage =="sauna") {?>
class="active" <?php } ?>
Put all the below code in menu.php and everything will be taken care of.
// function to get the current page name
function PageName() {
return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}
$current_page = PageName();
Use the above to get the current page name then put this in your menu
<li><a class="<?php echo $current_page == 'offnungszeiten.php' ? 'active':NULL ?>" href="offnungszeiten.php">Öffnungszeiten</a></li>
<li><a class="<?php echo $current_page == 'sauna.php' ? 'active':NULL ?>" href="sauna.php">Sauna</a></li>
<li><a class="<?php echo $current_page == 'frauensauna.php' ? 'active':NULL ?>" href="frauensauna.php">Frauensauna</a></li>
<li><a class="<?php echo $current_page == 'custom.php' ? 'active':NULL ?>" href="custom.php">Beauty Lounge</a></li>
<li><a class="<?php echo $current_page == 'feiertage.php' ? 'active':NULL ?>" href="feiertage.php">Feiertage</a></li>
where active is the name of the class which will highlight your menu item
there is two things you can do.
first you can read the current filename of the php file you request by using $_SERVER['PHP_SELF'] or $_SERVER['REQUEST_URI'] or any other $_SERVER global variables that you can use to read your current page and compare it with the link's url, something like this
<a href="offnungszeiten.php" <?php if($_SERVER['PHP_SELF']=='offnungszeiten.php'){ ?>class="activatepage" <?php } ?> >
Öffnungszeiten
</a>
the second one is to create a variable that you can read globally that would store the current name of the current page, like this
<?php
$cur_page ="offnungszeiten"
?>
<a href="offnungszeiten.php" <?php if($cur_page=='offnungszeiten'){ ?>class="activatepage" <?php } ?> >
Öffnungszeiten
</a>
I have done it with php in this way,
function createTopNav($active)
{
$pages = array(
array(
'name'=>'Home',
'link'=>'index'
),
array(
'name'=>'Smartphone',
'link'=>'smartphone'
),
array(
'name'=>'Tablet',
'link'=>'tablet'
),
array(
'name'=>'About Us',
'link'=>'about'
),
array(
'name'=>'Contact Us',
'link'=>'contact'
)
);
$res = "<ul>";
$activePage = "";
foreach($pages as $key=>$val)
{
if($val['link']==$active)
{
$res.= "<li><a href='".$val['link']."' class='active' >".$val['name']."</a></li>";
}
else
{
$res.= "<li><a href='".$val['link']."'>".$val['name']."</a></li>";
}
}
$res.="</ul>";
return $res;
}
And then to call this function
echo createTopNav("about");
and the output will be like this
<ul>
<li>Home</li>
<li>Smartphone</li>
<li>Tablet</li>
<li>About Us</li>
<li>Contact Us</li>
</ul>
I solved this using jQuery/javascript by running the code below each time my any page is loaded:
$(document).ready(function () {
//Get CurrentUrl variable by combining origin with pathname, this ensures that any url appendings (e.g. ?RecordId=100) are removed from the URL
var CurrentUrl = window.location.origin+window.location.pathname;
//Check which menu item is 'active' and adjust apply 'active' class so the item gets highlighted in the menu
//Loop over each <a> element of the NavMenu container
$('#NavMenu a').each(function(Key,Value)
{
//Check if the current url
if(Value['href'] === CurrentUrl)
{
//We have a match, add the 'active' class to the parent item (li element).
$(Value).parent().addClass('active');
}
});
});
This implementation assumes your menu has the 'NavMenu' ID, and uses http://hostname/scriptname.php href attributes like so:
<ul id="NavMenu">
<li>Home</li>
<li>Smartphone</li>
<li>Tablet</li>
<li>About Us</li>
<li>Contact Us</li>
</ul>
Read the javascript comments to see what's going on. If you prefer to use a different href layout (like in your original example), you have to play with the CurrentUrl variable a bit to get it to use the same layout as your href attributes.
For me this was the easiest solution since I had an existing sites with a big menu and many pages, and wanted to avoid having to modify all pages. This allows me to throw in a piece javascript code in the header file (which was a central file already) which solves the problem for all existing pages.
A bit late on the ball, but I just had to solve this myself and ended up using this Javascript method, with a small modification. This has the advantage on not requiring many changes to the current code, just run the script and voila.
window.onload = activateCurrentLink;
function activateCurrentLink(){
var a = document.getElementsByTagName("A");
for(var i=0;i<a.length;i++)
if(a[i].href == window.location.href.split("#")[0])
a[i].className = 'activelink';
}
Send page name in query string and check it on every page by getting the variable.
Simplere solution:
Borrowing the code from asprin above;
Create a new file menu.php where you will store the one and only copy of the menu. In this file, you will create a function addMenu($pageName) that take a parameter as the page name and returns a string consisting of the menu after having added the current tag.
In your HTML code, you would include(menu.php) and then call the function addMenu with the current page name. So your code will look like this:
menu.php
<?php
function addMenu($pageName){
$menu =
'<ul>
<li><a href="Öffnungszeiten.php"' . ($pageName == "Öffnungszeiten" ? "class=\"current\"" : "") . '><span>Öffnungszeiten</span></a></li>
<li><a href="sauna.php"' . ($pageName == "Öffnungszeiten" ? "class=\"current\"" : "") . '><span>Sauna</span></a></li>
<li><a href="frauensauna.php"' . ($pageName == "Frauensauna" ? "class=\"current\"" : "") . '><span>Frauensauna</span></a></li>
<li><a href="custom.php" ' . ($pageName == "lounge" ? "class=\"current\"" : "") . '><span>Beauty Lounge</span></a></li>
<li><a href="Feiertage.php"' . ($pageName == "feiertage" ? "class=\"current\"" : "") . '><span>Feiertage</span></a></li>
</ul>';
return $menu;
}
?>
And in your HTML, say this:
<div id="menu">
<?php
include('menu.php');
echo addMenu("index");
echo $hello;
?>
</div>
This worked for me:
function active_page($script){
$actual = basename($_SERVER['PHP_SELF']);
if($script == $actual){
return 'active-page'; //class name in css
}
}
I have some simple example, see below:
<?php
function active($currect_page) {
$url = $_SERVER['REQUEST_URI'];
if($currect_page == $url){
echo 'active';
}
}
?>
<ul class="navbar-nav mr-auto">
<li class="nav-item <?php active('/');?>">
<a class="nav-link" href="/">Home</a>
</li>
<li class="nav-item <?php active('/other');?>">
<a class="nav-link" href="/other">Other page</a>
</li>
</ul>
Better late than never - I like to keep it simple, to be honest, especially if there's a ton of scripting and PHP going on.
I place this code on the top of each page to identify the page:
<?php
$current_page = 'home';
include 'header.php';
?>
Then your menu/navigation (mine is bootstrap 4) looks like this:
<ul class="navbar-nav mx-auto">
<li class="nav-item <?php if ($current_page=="home") {echo "active"; }?>">
<a class="nav-link" href="<?php echo SITEURL;?>/">Home</a>
</li>
<li class="nav-item <?php if ($current_page=="about") {echo "active"; }?>">
About
</li>
<li class="nav-item <?php if ($current_page=="store") {echo "active"; }?>">
Store
</li>
<li class="nav-item <?php if ($current_page=="news") {echo "active"; }?>">
News
</li>
<li class="nav-item <?php if ($current_page=="contact") {echo "active"; }?>">
Contact
</li>
</ul>
I'm not saying this is the optimal method, but it works for me and it's simple to implement.
adding this:<?= ($activePage == 'home') ? 'active':''; ?> to my link it works perfectly, I only can't make the child of a submenu working to make the parent active.
Assume you have a navbar with the following items:
<ul>
<li id="menu-item-home">HOME</li>
<li id="menu-item-services">SERVICES</li>
<li id="menu-item-about-us">ABOUT US</li>
<li id="menu-item-contact">CONTACT</li>
</ul>
Then, declare a javascript variable in each page as below:
<script>
<?php echo("var active = 'menu-item-home';"); ?>
</script>
The variable "active" is assigned with the corresponding item of each page.
Now, you can use this variable to highlight the active menu item as below.
$(window).ready(function(){$("#" + active).addClass("active");});
I have a similar issue with my web app menu.
I also have sub menus which do not appear as top level menu buttons.
My solution is as follows:
a) Partial php file with menu html and a little php function at the top that checks GET variables against the menu buttons.
I have two GET variables to check: the page and (if necessary) the menu_button.
b) Adding any new php page with a href links to either menu pages or sub menu pages.
The variable "menu_button" is optional and can be used to link to submenu php files.
Of course the security concerning GET variables should be considered.
From my point of view, this solution has less effort than having to maintain an array of pages or links somewhere.
You just use a get variable "menu_button" where you pass the top level menu button that should be marked visually in any link which targets your php file.
Code examples:
Partial menu.php (has to be included in every php file):
<?php
function active($page_link){
$menu_button = $_GET("menu_button") ?: $_GET("page"); // sets the menu button either to the given top level menu or it defaults to the page itself
if($menu_button === $page_link) return "active";
}
?>
<div>
<a href="?page=one" class="<?= active('one') ?>"Link one</a>
Link two
</div>
Any php file with links to sub menu file:
<div>
Link one
Link to sub menu page "three" of menu "two"
</div>
Works for me. Hope someone else can use this.
For making a dynamic active menu link I follow this method.
first, In the menu link, I always use the full address:
//HTML CODE
<ul class="menu">
<li>
Home
</li>
<li>
About us
</li>
<li>
Contact
</li>
</ul>
//Javacript Code
const menus = document.querySelectorAll('.menu li a');
menus.forEach((menu) => {
const currentLocation = window.location.href;
if (currentLocation === window.origin) {
menus[0].classList.add('active');
} else if (menu.href === currentLocation) {
menu.classList.add('active');
} else {
return;
}
});
and then I will use vanilla javascript code to do the rest
You can use
<?php
function active($current_page){
$page = $_GET['p'];
if(isset($page) && $page == $current_page){
echo 'active'; //this is class name in css
}
}
?>
<ul>
<li><a class="<?php active('page1');?>" href="?p=page1">page1</a></li>
<li><a class="<?php active('page2');?>" href="?p=page2">page2</a></li>
<li><a class="<?php active('page3');?>" href="?p=page3">page3</a></li>
<li><a class="<?php active('page4');?>" href="?p=page4">page4</a></li>
</ul>
I'm still new to Front End Development and working on my first really big site / wordpress blog.
So my question is this, I have a Menu that will be the same on all pages on the site. However each section will have it's name highlighted in the Menu Nav.
Current Nav_Bar markup:
<div id="nav_bar">
<ul class="nav">
<li class="nav_li">Home</li>
<li class="nav_li">About</li>
<li class="nav_li selected">Blog</li>
<li class="nav_li">Book</li>
<li class="nav_li">Media</li>
<li class="nav_li">Events</li>
<li class="nav_li">Services</li>
<li class="nav_li">Contact</li>
<li class="search">
<input type="text" onfocus="if(this.value == 'Search') { this.value = ''; }" value="Search" />
</li>
<li class="search_btn">
<div class="search_button">Go</div>
</li>
</ul>
</div><!-- nav_bar -->
Now I've build pages before using this simple PHP code: <?php include("menu.php"); ?>
However, how would you guys 1st: organize this menu to accept and incoming value, like menu.php+select="home" and 2nd how would you pass in that value to add a class of selected to one of the Menu items?
First off your class on li "nav_li" is redundant and could be removed. Use .nav li in place to ref these list items with less lines of code. This works both as a JQuery selector and CSS selector. Second, to answer you actual question; I would use the active class as follows:
// Assuming the following html. <ul class="nav"><li>About</li></ul>
$('.nav li').click(function() {
$('.nav li.active').removeClass('.active');
$(this).addClass('.active');
window.location = $(this).children('a').attr('href');
return;
});
Now in the area where you keep your navbar you check to see if the current url is active by the following:
<?php
$currentUri = $_SERVER['REQUEST_URI'];
<ul class="nav">
<li class="<?php if($currentUri == '/about.php') {echo 'active';} ?>">About</li>
</ul>
Add the condition in the php script to each list item.
Sincerely,
Kevin
I assume you want your 'incoming value' for the purpose of highlighting a menu item (rather than displaying a particular page)? It's unnecessary, because the browser already knows what page it's on.
This is one way of highlighting the current page in jQuery:
$('.nav li a').each(function(){
var link = $(this).attr('href'),
current_page = location.href;
if(current_page.indexOf(link) != -1) {
$(this).addClass('current-page');
}
});
Before the include, set a value in some parameter, like $page = 'blog' and then in the menu.php
<li class="nav_li<?php echo $page === 'blog' ? " selected='selected'" : "" ?>">Blog</li>
This can be done using javascript
var url=document.location.toString();
if(url=="http://www.something.com/some.php")
{
//code to add class to specific link
}
else if(url=="http://www.something.com/someelse.php")
{
//code to add class to specific link
}
You can also do this on server side in menu.php
$url=$_SERVER['REQUEST_URI']
Then check the url and add class name accordingly
If I'm understainding what you're after, maybe something like:
index.php:
<?php
$page = 'home';
// page code ...
?>
about.php:
<?php
$page = 'about';
// page code ...
?>
etc, etc...
Then menu.php tweaked slightly:
<div id="nav_bar">
<ul class="nav">
<li class="nav_li home">Home</li>
<li class="nav_li about">About</li>
<li class="nav_li blog">Blog</li>
<li class="nav_li book">Book</li>
<li class="nav_li media">Media</li>
<li class="nav_li events">Events</li>
<li class="nav_li services">Services</li>
<li class="nav_li contact">Contact</li>
<li class="search">
<input type="text" onfocus="if(this.value == 'Search') { this.value = ''; }" value="Search" />
</li>
<li class="search_btn">
<div class="search_button">Go</div>
</li>
</ul>
</div><!-- nav_bar -->
and finally some javascript:
<script>
$(function () {
$('#nav_bar li.<?=$page?>').addClass('selected');
});
</script>
That assumes jQuery is being used, but it isn't necessary obviously, the same could be done with straight javascript.
