How do you store a multi-array type of data into a cookie.
For example: [[1, 'foo'], [2, 'bar'], [3, 'foobar']]
I can get it to work with a single dimensional array as such:
cookies[:foobar] = { :value => cookies[:foobar] << ",1" }
and then do
cookies[:foobar].split(',').include?("1")
To verify that 1 exists inside the cookie. Not too sure how I can get around this with a multidimensional array

Example - store array in a cookie: var arr = ['foo', 'bar', 'baz']; var json_str = JSON. stringify(arr); createCookie('mycookie', json_str);
Cookies can hold only strings. If you want to simulate an array you need to serialize it and deserialize it.
Cookies are basically text, so you can store an array by encoding it as a JSON string (see json_encode ). Be aware that there is a limit on the length of the string you can store though.
Store objects in the Cookies The cookies store information in the string format only. If users want to store any other types of data in the cookies, they need to convert it to the string using the stringify() method. In this section, we will convert the object to a string and store it in cookies.
Serialize array into json and store to cookies.
Look at two methods:
ActiveSupport::JSON.encode(object)
ActiveSupport::JSON.decode(string)
The easiest is probably to use one of the serialisation methods rails/ruby provides such as YAML, marshalling or json.
