Facebook Ads Custom Tracking Installation

This tiny little library allows you to track your facebook campaign ids with your orders.

Step 1

First copy the codes below and place them right before the closing body tag in your landing page.

<script type="text/javascript">
if (window.location.search != '') {
	var fb_campaign_id = ''; //utm_medium
	var fb_utm_source = '';
	var fb_ad_id = ''; //utm_content
	var fb_adset_id = ''; //utm_campaign
	var search_items = window.location.search;
	search_items = search_items.replace('?', '');

	var buildLink1 = '';
	var buildLink2 = '';
	var buildLink3 = '';

	search_items = search_items.split('&&');
	for(i=0;i<search_items.length;i++){
	    var thisItem = search_items[i];
		var getCampaign = thisItem.split("=");
	    if(thisItem.indexOf('utm_medium') > -1){
	        fb_campaign_id = getCampaign[1];
	        buildLink1 = 'attributes[fb_campaign_id]='+fb_campaign_id;
	    }
		
	    if(thisItem.indexOf('utm_campaign') > -1){
	        fb_adset_id = getCampaign[1];
	        buildLink2 = 'attributes[fb_adset_id]='+fb_adset_id;
	    }
		
	    if(thisItem.indexOf('utm_content') > -1){
	        fb_ad_id = getCampaign[1];
	        buildLink3 = 'attributes[fb_ad_id]='+fb_ad_id;
	    }
	}

	//update link
    var buyLinkList = document.getElementsByClassName('buyBtn');
	for(i=0;i<buyLinkList.length;i++){
		var itz_url = buyLinkList[i].href;
		var concutter = '?';
		if (itz_url.indexOf('?') > -1) {
			concutter = '&';
		}
	    var newURL = buyLinkList[i].href+concutter+buildLink1+'&'+buildLink2+'&'+buildLink3;
	    buyLinkList[i].href=newURL;
	}

}
</script>

Step 2

All buy now buttons need to have the class name buyBtn

<a href="xxxxx" class="buyBtn XXX XXX XXX">Buy Now</a>

Explanation

It captures the utm_medium which is the campaign id ( https://promo.elevatione.com/us/neck-promo?utm_source=Facebook_Ads&utm_medium={{campaign.id}}&utm_campaign={{adset.id}}&utm_content={{ad.id}}) and sets as the cart attribute in the buy now button urls.
