count the items in an RFG inside an RFG and use it in condition

This thread is resolved. Here is a description of the problem and solution.

Problem:
The user would like to display a different icon based on the count of nested RFG items in a nested view.

Solution:
Toolset does not offer built-in feature to count the number of items in an RFG. It will require custom code.

However, based on how the user has set up the nested view, we can implement a solution using Javascript. Check this reply https://toolset.com/forums/topic/count-the-items-in-an-rfg-inside-an-rfg-and-use-it-in-condition/#post-2041359

I could not make the custom code return the count of the images in each unit, either using the view, or using the relationship API(toolset_get_related_posts). However, I was able to come up with a Javascript-based solution that is optimal.

Instead of counting the number of images using a shortcode or a function in the server, which will trigger more database queries and increase the page load, I added a special class(no-unit-image) to the wpv-no-items-found section of the view:

	[wpv-no-items-found]
		[wpml-string context="wpv-views"]<small class="no-unit-images"></small>[/wpml-string]
	[/wpv-no-items-found]

Then using a Javascript, I search for this class, which means the unit does not have any images, and then, I apply the greyscale style for the image button.

jQuery(function($){
    $('.no-unit-images').each(function(){
        var $this = jQuery(this)
        var container = $this.closest('.ml-0');
        var image = container.find('.btn-unit-img>img');
        image.attr('style', 'webkit-filter: grayscale(100%); filter: grayscale(100%);')
    })
})

Please check if that's what you are looking for hidden link
