jquery - How best to capture referring URL in form using cookie?

Question

I'm using the Wordpress Contact Form 7, setting a Cookie refurl using the Cookie Monster plugin. Using these tools (or any other), what is the easiest way to set a cookie that captures the referring URL and then adds this to a hidden field in a Contact Us form?

Answer 1

With the cookie plugin.

Let's say that the cookie is called "refurl"

You can access it using:

var refURL = $.cookie("test");

You can append an element to your form by selecting it and adding the input to it. Let's say the id of your form is ContactUsForm :

var $el = $("<input />").attr("type","hidden").attr("value",refURL);
$("#ContactUsForm").append($el);
