    For each item, display its image

    I have some images in the media storage, and I have a "ProductItem" that has a media picker property "productImage". I've read multiple threads and documentation but nothing seems to work. Just want to display the information of each item, including the image.

    @inherits Umbraco.Web.Mvc.UmbracoViewPage<ContentModels.Products>
    @using ContentModels = Umbraco.Web.PublishedModels;
    @{
        Layout = "Master.cshtml";
    
        var products = Umbraco.Content(Guid.Parse("2740e0b9-caf3-435a-89c5-982ed890e6bd"))
            .ChildrenOfType("ProductItem")
            .Where(x => x.IsVisible())
            .OrderByDescending(x => x.CreateDate);
    
    
    }
    
    @foreach (var product in products)
    {
      <section class="page-section">
        <div class="container">
          <div class="product-item">
            <div class="product-item-title d-flex">
              <div class="bg-faded p-5 d-flex ml-auto rounded">
                <h2 class="section-heading mb-0">
                  <span class="section-heading-upper">@product.Value("productSubtitle")</span>
                  <span class="section-heading-lower">@product.Value("productTitle")</span>
                </h2>
              </div>
            </div>
            <img class="product-item-img mx-auto d-flex rounded img-fluid mb-3 mb-lg-0" src="" alt="">
            <div class="product-item-description d-flex mr-auto">
              <div class="bg-faded p-5 rounded">
                <p class="mb-0">@product.Value("productContent")</p>
              </div>
            </div>
          </div>
        </div>
      </section>
    }
    

    Naturally, the first thing I tried was "@product.Value("productImage")", but obviously that didn't work, so I read through many different forum threads and documentation. Either I've done something wrong or the things I read are outdated because I can't seem to display my images. Any help much appreciated!

    I'm using the latest version of Umbraco

    Hi Ras,

    First of all welcome to Our :)

    A good place to get an idea how work with the media picker will be this

    https://our.umbraco.com/documentation/getting-started/backoffice/property-editors/built-in-property-editors/media-picker/

    In the link you will find some good examples on how to get the image via Razor

    Hope this helps.

    /Dennis

    Thanks!

    I read that part of the documentation earlier, but the examples either don't seem to work, or simply doesn't have a good example for my specific use. When inside my loop of product items, applying those methods is very confusing and there isn't much further explanation

    Hi Ras

    One thing you could try is

    @product.Value("productImage").Url

    Let me know if this works for you or not

    I figured the solution would be something along those lines but it throws me an error.

    Compiler Error Message: CS1503: Argument 1: cannot convert from 'method group' to 'object'
    

    Calling the Url() method also throws an error

    Compiler Error Message: CS1929: 'object' does not contain a definition for 'Url' and the best extension method overload 'PublishedContentExtensions.Url(IPublishedContent, string, UrlMode)' requires a receiver of type 'IPublishedContent'

    Okay

    Then you should be able to do the following inside the for each loop

    var typedMultiMediaPicker = product.Value<IEnumerable<IPublishedContent>>("productImage");
        foreach (var item in typedMultiMediaPicker)
        {
            <img src="@item.Url" />
        }
    

    Hope this can help you Ras,

    Best,

    -Dennis

    For some reason the value in

    product.Value<IEnumerable<IPublishedContent>>("productImage");
    

    Is null, this is the error I get:

    Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
    
    Source Error:
    
    
    Line 26:             @{ 
    Line 27:                 var media = product.Value<IEnumerable<IPublishedContent>>("productImage");
    Line 28:                 foreach(var item in media)
    Line 29:                 {
    Line 30:                     <img src="@item.Url()"/>
    

    But productImage is the name and each item has an image assigned to it through the media picker so I'm not sure why it's doing this.

    Okay Ras, then if i was you then I will try to print out the media variable to see if you get a value or not

    So something like @media.Name

    Doing this also gives me a NullReferenceException. Seems like it's not finding any published content with this name .. but I definitely did publish it.

    Update: Ended up solving it by deleting the productitem template and making a nested element instead, this allowed me to display the image.
