Multiple if/then arguments in PHP for HTML classes - php

I would like to have an if/then argument for 2 classes (from the css) for a menu item. One where the menu item is blue if it is NOT the active page, and one where the menu item is red if it IS the active page. I have figured out the active page portion, now I am trying to figure out the if it is not active portion. I hope that makes sense. I have included a code snippit below.
<ul class="menu ul">
<li><a class="Blue <?php if($page =='home'){echo 'active';}?>" href="../index.php" >Home</a></li>
I have tried multiple variations, however I cannot figure it out. Thanks for your help!

Oleksandr is correct: It's better to have your links styles blue by default and overwrite it with the active class.
If you would want to give a hyperlink either one class or the other based on a simple condition, I would recommend this syntax:
<ul class="menu ul">
<li>
<a class="<?= $page == 'home' ? 'active' : 'Blue' ?>" href="../index.php" >Home</a>
</li>
</ul>
The example above uses the ternary operator and the echo shortcut syntax, and simply echoes one of two values based on the outcome of the condition.

as far as I understood you want to add different classes to link depending on $page variable.
for this i would recommend you to just use else statement
<ul class="menu ul">
<li><a class="<?php if($page =='home'){echo 'Blue';}else{echo 'Red';} ?>" href="../index.php" >Home</a></li>`
However it would be much better to check state of $page somewhere up (to not make spagetti code). And then echo only class in the a element.
<?php if($page =='home'){$menu_class='Blue';}else{$menu_class= 'Red';};?>
<ul class="menu ul">
<li><a class="<?php echo $menu_class; ?>" href="../index.php" >Home</a></li></pre>

Alter class on every 1/5 entry with PHP

Using PHP to generate out a list.
I Simply want to set a different class on every fifth entry. (1/5), (4+1)
<li class="<?php the_code();?>"> content </li>
Output would be like this
<li class="yolo"> Content </li>
<li class="yolo"> Content </li>
<li class="yolo"> Content </li>
<li class="yolo"> Content </li>
<li class="hello"> Content </li>
<li class="yolo"> Content </li>
<li class="yolo"> Content </li>
<li class="yolo"> Content </li>
<li class="yolo"> Content </li>
<li class="hello"> Content </li>
How can i do this ?
Guess it's pure basic for anyone with php skills, that's not me but i would also be glad to get pointed towards some page that explains this so i can learn it.
To clarify am using Wordpress loop and it contains +100 items and i want to alter class on item 5,10,15,20,25,30,35 etc..
You can use a counter ($i) and increment it on each time you create a new list item (++$i), then check to see if the result is divisible by 5 (% 5 == 0). Then simply use the ternary operator (?…:…) to decide which value to output:
<?php $i = 0; ?>
<?php for(...) { ?>
<li class="<?= (++$i) % 5 == 0 ? 'yolo' : 'hello' ?>"> content </li>
<?php } ?>
But it truth, there's no need to even use PHP, when a little CSS will probably do the job:
li:nth-child(5n)
{
...
}
See a demonstation here.
As a drop in function for the code you provided:
function the_code() {
static $count = 0;
$count++;
echo $count % 5 == 0 ? 'hello':'yolo';
}
the static keyword in the function keeps the value of count whenever the function is called.

How to set current page "active" in php

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>

Can anyone suggest a way I can get my class="selected" to work on my navigation in Wordpress?

Can anyone suggest a way I can get my class="selected" to work on my navigation in Wordpress?
I have a wordpress navigation setup:
If I am on the home page, my home page class is selected.
If I want to go to page one, I want this class to change in thenavigation so only this class loads and not the home page.
I use: class="selected" to activate my roll over effect.
I can get this to work on a fixed site, just not on wordpress, any suggestions here?
<div class="nav">
<ul>
<li class="selected">Home</li>
<li>One</li>
<li>Two</li>
<li>Three</li>
<li>Four</li>
<li>Five</li>
<li>Six</li>
</ul>
</div>
Could I use an if statement here?
<?php if(is_home() ) {
//for example load class="selected"
} else {
//for example if other page don't load class="selected"
} ?>
From what I understood, you're using a hardcoded navigation, and not wp_nav_menu() from WordPress.
So, you can conditionally check for each page you are using:
<div class="nav">
<ul>
<li<?php echo is_home()? ' class="selected"'; '';?>>
Home
</li>
<li<?php echo is_page('Contact')? ' class="selected"'; '';?>>
Contact page
</li>
<li<?php echo is_single('My first Post')? ' class="selected"'; '';?>>
Myfirst post
</li>
</ul>
</div>
You should make use of the Conditional Tags present in WordPress.
If you look at the first <li> you will see <?php echo is_home()? ' class="selected"'; '';?> This code is expressed as a ternary operator which is the equivalent of
if( is_home() ){
echo ' class="selected"'; #echo class. white space in front so that it does not stick to the "<li"
else{
echo ''; #do nothing
}
In the example above, I used three functions:
is_home() - Returns true if you are on the home page
is_page($arg) - Returns true if you are on the page specified by $arg.
is_single($arg) - Returns true if you are on the post specified by $arg.
There are other conditional tags available that you can choose to use.

Set active state on navigation dynamically

I seem to run into this problem frequently and can never find a solution. I have a Wordpress site with a top navigation. Since this is in my header.php, and used on all pages, I cannot hardcode my active menu state for each page.
How can I dynamically set the activate state to work for each page?
Here is my current nav code:
<nav id="main-menu" class="padbot">
<ul id="ce">
<li class="cemenu">About</li>
<li class="cemenu">Consulting</li>
<li class="cemenu">Intelligence</li>
<li class="cemenu">Academy</li>
<li class="cemenu">Blog</li>
<li class="cemenu">Contact</li>
</ul>
I've already setup a CSS class called "active" that has my active state properties. Ideally, what I'm looking for is when your on the "About" page (or any of the other pages), the class I created for the active state will be appended to the current li classes's.
Example:
<li class="cemenu active">About</li>
Thanks!
you could try something along the lines of
<li class="cemenu<?php echo ($_SERVER['PHP_SELF'] == '/about' ? ' active' : '');?>">About</li>
You can do this way:
This will add the active class to the <a> which contains the page from the url.
$(function(){
var url = window.location.href;
var page = url.substr(url.lastIndexOf('/')+1);
$('.cemenu a[href*="'+page+'"]').addClass('active');
});
and if you want to add class to its parent li the replace the last line to this and css class should be like this:
.active a{
css
properties
for active li's a
}
// using closest
$('.cemenu a[href*="'+page+'"]').closest('li').addClass('active');
or
// using parent
$('.cemenu a[href*="'+page+'"]').parent('li').addClass('active');
just tryout the fiddle here
First, there is a css pseudo class prepared for styling 'active' links :
a:active {css}
For your situation, you would have to add this class to your styling :
.active a, a:active {css}
But your needs seems more on the PHP side than the CSS, perhaps someone else will help you with that part. There would be a javascript solution with jQuery, finding the actual location then inject a css selector to the proper element.
Check this article and this other one about wordpress. It will help you.
Stack Overflow references :
How do I target each menu different items on active state in Wordpress
How to add Active states and icons in wordpress wp_nav_menu()

google search
try something like this:
<?php $pages = array('about' => 'About Us', 'blog' => 'blog') ?>
<ul>
<?php foreach($pages as $url => $page): ?>
<?php $isActive = $_SERVER["REQUEST_URI"] == $url ?>
<li<?php echo $isActive ? ' class="active"' : '' ?>>
<?php echo $page ?>
</li>
<?php endforeach ?>
</ul>
It may be worth looking into using wordpres functions such as get_page_link which would be nicer than using the Server super global as that's not nice. This would also fail if you have wordpress in a folder and not the document root, it's just a simple example to get you started :)
You can try like this
<li class="<?php
if($this_page=='Home'){
echo 'active';
}
?>">
Home
</li>
<li class="<?php
if($this_page=='Contact'){
echo 'active';
}
?>">
Contact
</li>
And then in your home page
$this_page='Home';
And in your contact page
$this_page='Contact';
You could use preg_replace() to add class="active" like this:
ob_start();
echo '<ul>
<li>Page 1</li>
<li>Page 2</li>
</ul>';
$output = ob_get_clean();
$pattern = '~<li><a href="'.$url.'">~';
$replacement = '<li class="active"><a href="'.$url.'">';
echo preg_replace($pattern, $replacement, $output);

suggest proper conditional statement to fade tabs with CSS via PHP

I want to change the class of two tabs via PHP, but I am stuck in basic condition. here is my code:
CSS
.myinfo { background-color:black }
.deactive { background-color : white }
HTML
<li class="myinfo <?=$deact?>">
<a href="myaccount.php?<?=$qry_str?>" >My Info</a>
</li>
<li class="myinfo <?=$deact?>">
My Contacts
</li>
What I need is
if $_GET['mycontacts'] is active
then My Info link should have class deactive
otherwise My Contacs link should have class deactive
I tried this:
if (isset($_GET['mycontacts'])){
$deact ='deactive';
}
But it did not succeed. Please help to write this condition (I think a one line ternary condition could work).
Try this:
<li class="myinfo <?php echo ($_GET['mycontacts'] === 'active' ? 'deactive' : '') ?>">
<a href="myaccount.php?<?=$qry_str?>" >My Info</a>
</li>
<li class="myinfo <?php echo ($_GET['mycontacts'] !== 'active' ? 'deactive' : '') ?>">
My Contacts
</li>
By the way I hate php short tags! Personal preference...
