    isHelpers 'Help'

    Hi All,

    I have the following code 

    @{
    //gets the home page using doc type alias (root node)
    var siteRoot = Model.Content.AncestorOrSelf("homePage");
    //gets the products page using doc type alias
    var galleryPage = siteRoot.Descendant("galleryPage");
    //get the latest photos using the album media folder id
    var latestPhotos = galleryPage.HasValue("album") ? Umbraco.TypedMedia(galleryPage.GetPropertyValue<int>("album")) : null;
}

        @if (latestPhotos != null)
        {
            foreach (var photo in latestPhotos.Children.OrderBy("createDate desc"))
            {
                <div class="item @(photo.IsPosition(1, "col-xs-6", "col-md-2 col-sm-3 col-xs-4"))">
                    <a href="@photo.Url" data-gallery><img class="img-responsive" src="@photo.GetCropUrl(320,320)" alt="" /></a>
                </div>
            }
        }

    I am trying to use the isHelpers to test whether 'photo' is in the first two positions in my 'latestPhotos' list. Is that possible? My code above can successfully check if the photo is in position 1 then apply x class and if not apply y class.

    Is there a way to check against more than one position? I been reading this on the wiki

    Thanks

    Hi Paul,

    What about if you nested the checks. It's not something I've done before but this might do the job.

    @(photo.IsFirst("col-xs-6", photo.IsPosition(2, "col-xs-6", "col-md-2 col-sm-3 col-xs-4"))

    Hi Nik,

    Thansk for the response - I will take a look at whether this works. I was just looking for a better way of achieving the following and was wondering if the isHelpers could help

    @if (latestPhotos != null) { var indexCount = 0;

                    foreach (var photo in latestPhotos.Children.OrderBy("createDate desc"))
                {
                    if (indexCount == 0 || indexCount == 1)
                    {
                        <div class="item col-xs-6">
                            <a href="@photo.Url" data-gallery><img class="img-responsive" src="@photo.GetCropUrl(640,480)" alt="" /></a>
                        </div>
                    }
                    else
                    {
                        <div class="item col-md-2 col-sm-3 col-xs-4">
                            <a href="@photo.Url" data-gallery><img class="img-responsive" src="@photo.GetCropUrl(320,320)" alt="" /></a>
                        </div>
                    }

                    indexCount++;
                }
            }

    Many thanks

    Paul
