Count Widgets WordPress

Question

Is there a way to count widgets in widgetized area in WordPress.

I need to add specific class for every 3rd widget.

For example:

<div class="widget-item">...</div>
<div class="widget-item">...</div>
<div class="widget-item foo">...</div>

<div class="widget-item">...</div>
<div class="widget-item">...</div>
<div class="widget-item foo">...</div>

and so on...

Thanks!

Answer 1

Maybe you could use the dynamic_sidebar_params hook for that.

Here's a tutorial for something not so different: http://wpshock.com/add-first-last-css-class-automatically-to-wordpress-widgets/

In the described solution, you keep a global variable for counting the currents sidebar widgets. So something like this should enable you to add a class to every 3rd widget:

if(($myGlobalCount % 3) == 0){
 //add a custom class
}

Answer 2

you could do this with CSS

div.widget-item:nth-child(3n){ 
}
