Override IpublishedContent.Url

Extending Umbraco and using the API

Umbraco 7

Hi!

I'm building a website where most of the pages can be modified by querystring parameter. For example if a parameter "member" is passed in the header renders a different logo. From that moment on all links should use it for further use. As I generally use the IPublishedContent.Url property to link to other pages it is probably the best solution to modify the URL property by just adding ?member=xxx to the URL globally. Is there any way to achieve this?

Create 2 Extension classes, 1 for Umbracohelper (if you use it) and 1 for IPublishedContent and 1 helper class for the shared logic.

public static string UrlWithCopiedParams(this UmbracoHelper umbracoHelper, IPublishedContent content, HttpRequestBase request)
    {
        return UrlParams(content, request);
    }
    public static string UrlWithCopiedParams(this IPublishedContent content, HttpRequestBase request)
    {
        return UrlParams(content, request);
    }

    private static string UrlParams(IPublishedContent content, HttpRequestBase request)
    {
        string[] allowedparameters = { "paramName1", "paramName2" };
        string parameters = "";

        if (allowedparameters.Count() > 0)
        {
            foreach (string param in allowedparameters)
            {
                if (!string.IsNullOrEmpty(request[param]))
                {
                    if (parameters.Length == 0)
                    {
                        parameters = string.Format("?{1}={2}", parameters, param, request[param]);
                    }
                    else if (parameters.Length > 1)
                    {
                        parameters = string.Format("{0}&{1}={2}", parameters, param, request[param]);
                    }
                }
            }
            return content.Url + parameters;
        }
        else
        {
            return content.Url;
        }
    }

And then use one of these 2 calls in your views(you will most likely use the second one)

@Umbraco.UrlWithCopiedParams(Model.Content,Request)
@IPublishedContent.UrlWithCopiedParams(Request)

If anyone can give me a workaround on how to get the Request without passing it, I would be gratefull.

Hi Sven,

See my example. The idea is pretty much the same. You can get the current request using HttpContext.Current.Request.

Hi Patric,

You could achieve this with an extension method on IPublishedContent:

public static class PublishedContentExtensions
{
    public static string MyUrl(this IPublishedContent content)
    {
        var member = HttpContext.Current.Request.QueryString["member"];

        if (string.IsNullOrEmpty(member))
        {
            return content.Url;
        }

        return content.Url + "?member=" + member;
    }
}

Put this class somewhere in your project and then in your views you'll be able to do something like this:

<a href="@Model.Content.MyUrl()">@Model.Content.Name</a>
