Does anyone know how to edit/change Wordpress's wp_list_pages function in order to add classes to the ul and li items?
I'm trying to implement the new version of jquery.treeview which requires <li class="expandable"> and <ul style="display: none;"> on expandable lists and child ul's.
I've been messing around with this but it aint working too good in that it applies the 'expandable' class to all li's:
$pages = wp_list_pages('title_li=&echo=0' );
$pages = preg_replace('/class="/','class="expandable ', $pages); //note space on end of replacement string
//output
echo $pages;
And here is what the outputted html should look like:
<ul class="treeview" id="tree">
<li>Home</li>
<li class="expandable">Expand 1
<ul style="display: none;">
<li class="expandable">Expand 2_1
<ul style="display: none;">
<li>Expanded 3_1</li>
<li>Expanded 3_2</li>
<li>Expanded 3_3</li>
</ul>
</li>
<li class="expandable"><a href="#" >Expand 2_2</a>
<ul style="display: none;">
<li>Expanded 4_1</li>
<li>Expanded 4_2</li>
<li>Expanded 4_3</li>
</ul>
</li>
</ul>
Hope this makes sense and any help greatly appreciated, S.
I guess you are trying to activate a tree view on the page items. As this would require JavaScript you can simply add the class using JavaScript before initializing the tree view:
$("#tree li").addClass("expandable");
$("#tree").treeview();
If you also want to hide all ul elements you can use jQuery, too (not sure about the correct syntax):
$("#tree ul").hide();
Maybe this Plugin (Classy wp-List) helps. I haven't tried it yet but it says it will let you define a class for each page in the backend.
good luck.

I would appreciate if you help me, the problem is that I have a menu and it has a submenu, and this submenu has a class by default - sub-menu, how can I change this class to submenu and how can I add to my first li - tag -
HTML:
<ul class="cf">
<li class="sub-menu">managers<i class="fa fa-angle-down fa-1g" aria-hidden="true"></i>
<ul class="submenu">
<li>page one</li>
<li><a href="shareholder.html">page two/a></li>
</ul>
</li>
</ul>
PHP:
<?php wp_nav_menu(array('theme_location'=>'menu', 'container'=>'false', 'menu_class'=>'cf', 'depth' => 2)); ?>
I don't know exaclty what you are trying to do. But you can find the submenu output in the file "wp-includes\class-walker-nav-menu.php".
The menu is build dynamically on the sub-menu class. So i don't know if the menu generator is still working if you change this class. Maybe it is better to add an additional class.
Try this code :
$(document).ready(function () {
$('ul.cf').find(".sub-menu").addClass("submenu").removeClass("sub-menu");
});
May be this will work for wordpress. Write this in your theme function.php
function change_submenu_class($menu) {
$menu = preg_replace('/ class="sub-menu"/','/ class="submenu" /',$menu);
return $menu;
}
add_filter('wp_nav_menu','change_submenu_class');
How can I create a function to scan all menu items from Drupal 7 system and if there is a nested ul, add dropdown CSS classes to the nested ul and add a custom attribute to the parent li container? Im using UIKIT which will automatically create the dropdowns.
Here's my current menu HTML output:
<ul class="menu">
<li class="first last expanded">
<a title="" href="/node/add">Add content</a>
<ul class="menu">
<li class="first leaf">
<a title="article" href="/node/add/article">Article</a></li>
<li class="leaf">
<a title="page" href="/node/add/page">Basic page</a></li>
<li class="last leaf"><a title="blog" href="/node/add/blog">Blog entry</a></li>
</ul>
</li>
</ul>
Here's what I need it to be:
<ul class="menu">
<li class="first last expanded" data-uk-dropdown>
<a title="" href="/node/add">Add content</a>
<ul class="menu uk-dropdown">
<li class="first leaf">
<a title="article" href="/node/add/article">Article</a></li>
<li class="leaf">
<a title="page" href="/node/add/page">Basic page</a></li>
<li class="last leaf"><a title="blog" href="/node/add/blog">Blog entry</a></li>
</ul>
</li>
</ul>
Im looking for the simplest approach possible.
You can crawl menu tree your self and write out menu HTML as you like. Used that and should be something like:
$tree = menu_tree_all_data('menu_machine_name');
Also, if I remember well, if you do only that your active (current) menu item won't be marked any way, and for marking it you have to also call (after getting $tree variable) :
menu_tree_add_active_path($tree);
But again, if I remember well, that function is only available if you install "Menu block" module...
Print out $tree variable after that and organize your code to crawl recursively menu tree you collected.
i ve done this below menu in php which is autogenerated with a function :
As you know, if i click on "Red Chicken", it will try to open a ../Red%20Chicken URL, which doesnt exist till it comes from a big table which change everytime.
What i want to do is : to know where we clicked (example : by generating the url and cut it ) and then redirect to a page like result.php (+ get something like the variable to know where do we come from). And of course, i don't want to create a .php page for each element of my table.
Is this thing possible ?
EDIT : i found a way, it's to change my function and how it generates the menu.
Not really what i wanted but it's okay.
<ul class=\"niveau1\">
<li class=\"sousmenu\"><a href=\"Food\">Food</li>

</ul>
</ul>
</ul>
<ul class=\"niveau1\">
<li class=\"sousmenu\">name</li>
</ul>

The PHP-Way would probably be to use URLs like <a href='menuhandler.php?sel=cow'>Cow</a>, and if you want to be lazy, you could also JS/jquery to manupulate the URLs and replace <a href="something">with a call in the style shown before - but then this would not work w/o JS, so it is not a real option IMHO.
changed my function to generate it in another way
<a href=\"Recette.php?var=food\">
Not really what i wanted but it's okay.
This is my first post so forgive as I am just new in the world of web development.
Normally, when I try to make a website, I create a file called header.html and footer.html so that I only change data once in all of the pages rather than having multiple same headers on many html files. And include them all in a php file together with the content and the php codes that comes per page.
Now my problem is because I only have 1 header, the css is designed in a way that whatever the current menu/tab is, it will be marked as "selected" so that its obvious to the user what page they are currently in.
My question is how do I solve this problem:
1.) To have the class="selected" depending on what the current page/url is.

Thank You :)
If you're looking for a non-javascript / php approach...
First you need to determine which nav-link should be set as active and then add the selected class. The code would look something like this
HTML within php file
Call a php function inline within the hyperlink <a> markup passing in the links destination request uri
<ul>
<li><a href="index.php" <?=echoSelectedClassIfRequestMatches("index")?>>Home</a></li>
<li><a href="about.php" <?=echoSelectedClassIfRequestMatches("about")?>>About</a> </li>
<li><a href="services.php" <?=echoSelectedClassIfRequestMatches("services")?>>Services</a> </li>
<li><a href="features.php" <?=echoSelectedClassIfRequestMatches("features")?>>Features</a></li>
<li>Support
<ul>
<li><a href="support1.php" <?=echoSelectedClassIfRequestMatches("support1")?>>Support 1</a></li>
<li><a href="support2.php" <?=echoSelectedClassIfRequestMatches("support2")?>>Support 2</a></li>
</ul>
</li>
</ul>
PHP function
The php function simply needs to compare the passed in request uri and if it matches the current page being rendered output the selected class
<?php
function echoSelectedClassIfRequestMatches($requestUri)
{
$current_file_name = basename($_SERVER['REQUEST_URI'], ".php");
if ($current_file_name == $requestUri)
echo 'class="selected"';
}
?>
You could ID each link and use JavaScript/Jquery to add the selected class to the appropriate link.
<!--Menu Starts-->
<div class="menu">
<div id="smoothmenu" class="ddsmoothmenu">
<ul>
<li id="home-page">Home</li>
<li id="about-page">About </li>
<li id="services-page">Services </li>
<li id="features-page">Features</li>
<li id="support-page">Support
<ul>
<li id="support1-page">Support 1</li>
<li id="support2-page">Support 2</li>
</ul>
</li>
</ul>
</div>
</div>
<!-- Menu Ends--!>
On your content page use jQuery to do something like:
$(document).ready(function(){
$("#features-page").addClass("selected");
});
Another method you could use is:
Add class element based on the name of the page
Give each link a separate id then use jQuery on the individual pages.
<li>Home</li>
<li>About </li>
<li>Services </li>
<li>Features</li>
<li>Support
<ul>
<li>Support 1</li>
<li>Support 2</li>
</ul>
</li>
On the services page:
$(document).ready(function(){
$("#services").addClass("selected");
});
Or even better as robertc pointed out in the comments, there is no need to even bother with the id's just make the jquery this:
$(document).ready(function(){
$("[href='services.php']").addClass("selected");
});
One variant on Chris's approach is to output a particular class to identify the page, for example on the body element, and then use fixed classes on the menu items, and a CSS rule that targets them matching. For example, this page:
<DOCTYPE HTML>
<head>
<title>I'm the about page</title>
<style type="text/css">
.about .about,
.index .index,
.services .services,
.features .features {
font-weight: bold;
}
</style>
</head>
<body class="<?php echo basename(__FILE__, ".php"); ?>">
This is a menu:
<ul>
<li>Home</li>
<li>About </li>
<li>Services </li>
<li>Features</li>
</ul>
</body>
...is pretty light on dynamic code, but should achieve the objective; if you save it as "about.php", then the About link will be bold, but if you save it as "services.php", then the Services link will be bold, etc.
If your code structure suits it, you might be able to simply hardcode the page's body class in the page's template file, rather than using any dynamic code for it. This approach effectively gives you a way of moving the "logic" for the menu system out of the menu code, which will always remain the same for every page, and up to a higher level.
As an added bonus, you can now use pure CSS to target other things based on the page you're on. For example, you could turn all the h1 elements on the index.php page red just using more CSS:
.index h1 { color: red; }
You can do it from simple if and PHP page / basename() function..
<!--Menu Starts-->
<div class="menu">
<div id="smoothmenu" class="ddsmoothmenu">
<ul>
<li><a href="index.php" <?php if (basename($_SERVER['PHP_SELF']) == "index.php") { ?> class="selected" <?php } ?>>Home</a></li>
<li><a href="about.php" <?php if (basename($_SERVER['PHP_SELF']) == "about.php") { ?> class="selected" <?php } ?>>About</a> </li>
<li><a href="services.php" <?php if (basename($_SERVER['PHP_SELF']) == "services.php") { ?> class="selected" <?php } ?>>Services</a> </li>
<li><a href="features.php" <?php if (basename($_SERVER['PHP_SELF']) == "features.php") { ?> class="selected" <?php } ?>>Features</a></li>
</ul>
</div>
</div>
Sorry for my bad English, however may be it could help. You can use jQuery for this task. For this you need to match the page url to the anchor of menu and then add class selected to it. for example the jQuery code would be
jQuery('[href='+currentURL+']').addClass('selected');
How to convert this :
<ul class="ulStyle">
<li class="liStyle">
<div class="first">
<div class="second">
menu1
</div>
</div>
</li>
</ul>
to wp_nav_menu
Too many div and class inside there, anyone can help me solve this problem?Thank you!
This can be accomplished using the nth-child() selector in css
see the codepen here
use this css:
.wp_nav_menu div:nth-child(1) {
background: blue;
}
.wp_nav_menu div:nth-child(2) {
background: red;
}
with the following markup:
<ul class="wp_nav_menu">
<li>
<div>
Foo
</div>
<div>
Bar
</div>
</li>
</ul>
As I see you are using a custom theme that have probably a Walker. In WordPress you can use a Walker to modify the HTML rendered by wp_nav_menu.
http://codex.wordpress.org/Function_Reference/Walker_Class
First, see if there is one, normally in theme/functions.php
Before starting with custom walkers, use the options before, after, link_before, link_after and items_wrap. See http://codex.wordpress.org/Function_Reference/wp_nav_menu
It will allow you to change the encapsulation of your menu items.
