Content Fragment Component Validation

@nitinl ,

I don't think any such feature is available in current CF component. While browsing/selecting the CF from the list it is pointing to CF location so that Content Editor can choose from the list.

 if you want to implement anything extra then you have to customize it. My advice is to train authors to choose the CF from the desired location.

Yo can implement the JS to validate the path that is entered by the editor and if it is not CF path then do not allow author to submit the dialog.

Thanks,

Aruna

Follow the below steps:

1. Overlay the contentfragment dialog from libs to apps. You can find the core component in this path: /libs/core/wcm/components/contentfragment/v1/contentfragment/cq:dialog/

2. Add a property "required" "Boolean" "true" to the fragmentPath field(/libs/core/wcm/components/contentfragment/v1/contentfragment/cq:dialog/content/items/tabs/items/properties/items/column/items/fragmentPath).

required    Boolean    true

Hi @nitinl ,

PFB MVP solution for this.

 //validaton property.

//script to validate the CF path

$(window).adaptTo("foundation-registry").register("foundation.validation.validator", {
	  selector: "[data-foundation-validation='fragmentpath.validation']",
	  validate: function(el) {
        var fragmentPath = el.value;
        var message = "";
   		$.ajax({
            url: "/bin/validateFragmentPath.json?fragmentPath="+fragmentPath,
            async: false,
            success: function(data) {
               if(!data.hasOwnProperty('success')){
		 message = "Invalid content path";
	        }              
            }
        });
        return message;
	  }
});

Servlet call to check if its a valid CF,
