Foreach Loop, then a content pickers page content? (7.4.3)

I have a for each loop that pulls each recipient. Each recipient has a content picker that selects a elf (separate doc type and page). From the sponsor I want to select two fields, first name and last name

Here's my code, I can't seem to get this one working.

@foreach (var item in CurrentPage.Recipient.Where("UmbracoNaviHide == false"))
                        {   <td>
                                @item.Id
                            </td>
                            <td>
                                @if(item.HasValue("elf")){
                                    var elfContent = item.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("elf");
                                    var elfBtn = Umbraco.TypedContent(item.GetPropertyValue<int>("elf"));
                                    foreach (var subItem in elfContent){
                                        <a href="@elfBtn.Url">
                                            @subItem.firstName @subItem.lastName        
                                        </a>
                                    }
                                }
                                else{
                                    <span>-</span>
                                }
                            </td>
                        }

Hi Rylan

This code works only with Property Value Converters enabled, do you have it? Property Value Converters are part of the core only since 7.6 version.

Thanks,

Alex

I'm not using 7.6 properties im running 7.4

I tried using multiple ways to make this work including 7.6 code and couldn't figure it out.

anyone?

Also tried this:

@foreach (var item in CurrentPage.Recipient.Where("UmbracoNaviHide == false"))
                        {
                            if(item.HasValue("elf")){
                                var elfBtn = Umbraco.TypedContent(item.GetPropertyValue<int>("elf"));
                                <a href="@elfBtn.Url">
                                    @elfBtn.firstName @elfBtn.lastName
                                    </a>
                            }
                            else{
                                <span>-</span>
                            }
                        }

Hi Rylan

Try this code:

@foreach (var item in Umbraco.AssignedContentItem.Children)
{
    if(item.HasValue("elf")){
        var elfBtn = Umbraco.TypedContent(item.GetPropertyValue<int>("elf"));
        <a href="@elfBtn.Url">
            @elfBtn.GetPropertyValue("firstName") @elfBtn.GetPropertyValue("lastName")
        </a>
    }
    else{
        <span>-</span>
    }
}

Do not mix dynamics with strongly typed models.

Thanks,

Alex

Thanks for the response Alex. But it didn't seem to work. It actually decided to break the loop. This is before I even get to the content picker in the loop.

enter image description here

If I leave it with (below):

                            @foreach (var item in CurrentPage.Recipient.Where("UmbracoNaviHide == false"))

I get this error:

Rylan, this code " @foreach (var item in CurrentPage.Recipient.Where("UmbracoNaviHide == false"))" and code that gives an error, can't work

Please use strongly typed objects.

CurrentPage is a dynamic object, try to avoid it.

Thanks,

Alex

This code isn't working because of this line:

@foreach (var item in Umbraco.AssignedContentItem.Children)

Rylan, try this loop instead:

@foreach (var item in Umbraco.AssignedContentItem.GetPropertyValue

Thanks,

Alex

It works fine normally when I don't try to pull specific fields from the content pickers page.

Normally the .Url .Name will work just fine.

I added

@foreach (var item in Umbraco.AssignedContentItem.GetPropertyValue("recipient"))

and get this error

This code is working for me:

@foreach (var item in Umbraco.AssignedContentItem.GetPropertyValue<IEnumerable<IPublishedContent>>("recipient").Where(x => x.IsVisible()))
{
    <td>
        @item.Id
    </td>
    <td>
        @if (item.HasValue("elf"))
        {
            var elfContent = item.GetPropertyValue<IEnumerable<IPublishedContent>>("elf");
            var elfBtn = Umbraco.TypedContent(item.GetPropertyValue<int>("elf"));
            foreach (var subItem in elfContent)
            {
                <a href="@elfBtn.Url">
                    @subItem.GetPropertyValue("firstName") @subItem.GetPropertyValue("lastName")
                </a>
            }

Thanks Alex, I tried that code outside of my current loop and it still isn't working. I get a "Value cannot be null."

Do you think I'm not calling the right Models?

at the top of the page I have:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage<ContentModels.RecipientList>

@using ContentModels = Umbraco.Web.PublishedContentModels;

Sep 19, 2017 @ 19:23

What line causes the problem?

Maybe problem with this line - Umbraco.AssignedContentItem.GetPropertyValue<>

What type of property is "recipient"?

Thanks,

Alex

Rylan 69 posts 253 karma points

Yes, it is a problem with that line.

Recipient is a document type.

Thanks for all the help so far, hoping to get this workign soon Lol.

Where are "Recipient" documents placed?

Are they under the current page?

Copy Link

Rylan 69 posts 253 karma points

Sep 19, 2017 @ 19:30

Yes the current page would "RecipientList" which only allows the doctype 'recipient' to be displayed on the list. If there's a way I can screenshare with you that could work.

Then iterate over child nodes like here:

@foreach (var item in Umbraco.AssignedContentItem.Children.Where(x => x.IsVisible()))
{
    <td>
        @item.Id
    </td>
    <td>
        @if (item.HasValue("elf"))
        {
            var elfContent = item.GetPropertyValue<IEnumerable<IPublishedContent>>("elf");
            var elfBtn = Umbraco.TypedContent(item.GetPropertyValue<int>("elf"));
            foreach (var subItem in elfContent)
            {
                <a href="@elfBtn.Url">
                    @subItem.GetPropertyValue("firstName") @subItem.GetPropertyValue("lastName")
                </a>
            }
        }
        else
        {
            <span>-</span>
        }
    </td>
}

New variant of code:

@foreach (var item in Umbraco.AssignedContentItem.Children.Where(x => x.IsVisible()))
{
    <td>
        @item.Id
    </td>
    <td>
        @if (item.HasValue("elf"))
        {
            var elfContent = item.GetPropertyValue<string>("elf").Split(',').Select(x => int.Parse(x));

            foreach (var subItemId in elfContent)
            {
                var elfContentNode = Umbraco.TypedContent(subItemId);

                <a href="@elfContentNode.Url">
                    @elfContentNode.GetPropertyValue("firstName") @elfContentNode.GetPropertyValue("lastName")
                </a>
            }
        }
