Hi there

You can probably just remove the

.Random(6)

from your example?

Jules

Add a multi node content picker, set the min and max to 6, to your homepage called "lecturers" - then loop through that.

See here for an example

https://our.umbraco.org/documentation/getting-started/backoffice/property-editors/built-in-property-editors/Multinode-Treepicker2

Hi ,

I have 48 (employees ids ) in the front page . The ids keep rotating when i refresh. Now i want to change it.

I want to have only 6 ids out of 48 ids to be permanent always. How can i stop the automatic rotation.

If i remove automatic rotation, all the 48ids are displaying in the front page.

var lecturers = Umbraco.Content(1186); foreach (var item in lecturers.Children.Where("Visible").Random(6))

Can you please help me.

Hi ,

Thanks for your replay. If i use Take , it is displaying the first 6 list. I don't want like that. I need to chose particular 6 ids out of 48 ids.

As Steve mentioned, use the Multinode Treepicker to choose the particular 6 lecturers you want to be shown on the homepage. There are a ton of examples of how to use the Multinode Treepicker, including at the example on the page Steve sent you to: https://our.umbraco.org/documentation/getting-started/backoffice/property-editors/built-in-property-editors/Multinode-Treepicker2

After you have given a solid attempt at using the MNTP, feel free to ask specific questions if you run into issues.

Hi All,

I am using Multinode Treepicker now . After I followed the whole procedure as suggested, I wrote @CurrentPage.fsMNTP which displays only ids. When i finish writing the code, it is not displaying anything.

This is my code:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{

foreach (var lecturers in CurrentPage.fsMNTP)
{
    var item = Umbraco.Content(lecturers);

    <a href="@item.Url">
    <div class="frontpage lecturer box">
        <div class="left">
        <img src="@item.profilePicture" />
        </div>
        <div class="right">
            <strong>@item.Name</strong>
            <p>
            @if (@item.introToLecturer.ToString().Length > 130) {
                @Html.Raw(@item.introToLecturer.ToString().Substring(0, 130))<text>...</text>
            }else{
                @Html.Raw(@item.introToLecturer.ToString())
            }
            </p>
        </div>

            <div class="clear"></div>
    </div>
                </a>
}
<div style="text-align: center">
<a style="color: #FFF!important; margin-top: 20px;" class="button small white" href="/foredragsholdere">Alle foredragsholdere</a>
</div>

}

I think you need to leave behind dynamic objects- they tend to just cause issues later!

Try this

    @foreach (var lecturer in Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("fsMNTP"))
{
    if (lecturer.HasValue("profilePicture"))
    {
        var lecturerProfilePicture = lecturer.GetPropertyValue<IPublishedContent>("profilePicture");
        <a href="@lecturer.Url">
            <div class="frontpage lecturer box">
                <div class="left">
                    <img src="@lecturerProfilePicture.Url" />
                </div>
                <div class="right">
                    <strong>@lecturer.Name</strong>
                    <p>
                        @{
                            var lecturerIntro = lecturer.GetPropertyValue<HtmlString>("introToLecturer");
                            if (lecturerIntro.ToString().Length > 130)
                            {
                                @Umbraco.Truncate(lecturerIntro, 130) <text>...</text>
                            }
                            else
                            {
                                @lecturerIntro
                            }
                        }
                    </p>
                </div>

                <div class="clear"></div>
            </div>
        </a>
    }
}

I've also simplified your truncate of the long intros.. I'm guessing your text is rich text - if it's not then this will probably error.

Hi,

What version of Umbraco are you using - and did you use the obsolete Multi node tree picker?

Try this;

@if (Model.Content.HasValue("fsMNTP"))
{
    var lecturerListValue = Model.Content.GetPropertyValue<string>("fsMNTP");
    var lecturerList = lecturerListValue.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(int.Parse);
    var lecturerCollection = Umbraco.TypedContent(lecturerList).Where(x => x != null);
    foreach (var lecturer in lecturerCollection)
    {
        if (lecturer.HasValue("profilePicture"))
        {
            var lecturerProfilePicture = Umrbaco.TypedMedia(lecturer.GetPropertyValue<int>("profilePicture"));
            <a href="@lecturer.Url">
                <div class="frontpage lecturer box">

Hi,

I've recreated this locally and it works. If the below still doesn't work can you please check the aliases in the code against what you have in the document type - also provide a screenshot of these fields (in the settings -> document types).

@if (Model.Content.HasValue("fsMNTP"))
    {
        var lecturerListValue = Model.Content.GetPropertyValue<string>("fsMNTP");

        var lecturerCollection = Umbraco.TypedContent(lecturerList).Where(x => x != null);

        foreach (var lecturer in lecturerCollection)
        {
            if (lecturer.HasValue("profilePicture"))
            {

            }
        }
    }

As you suggested, i pasted your code . The name and URL is working . The name and URL work only when the description and picture code is deleted.

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@if (Model.Content.HasValue("fsMNTP")) { var lecturerListValue = Model.Content.GetPropertyValue

    foreach (var lecturer in lecturerCollection)
    {
        if (lecturer.HasValue("profilePicture"))
        {

            <a href="@lecturer.Url">
                <div class="frontpage lecturer box">
                    <div class="left">

                    </div>
                    <div class="right">
                        <strong>@lecturer.Name</strong>

                    </div>

                    <div class="clear"></div>
                </div>
            </a>
        }
    }
}

Because I need to show the pictures and descriptions also . I am sure that there is a problem in picture and description coding part. Now i do not know how to make picture and display code. Can you please help me.

Hi Steve,

I provided a screenshot of these fields.

hi,

I think you need to change the upload to a media picker.

Steve

Hi ,

Fine. I have a little bit doubt ,

I have a main folder id (1186) , in the children ids (1101,1102,1103,1104,1105,1106). Can we connect main folder ids and children ids.

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{ var lecturers = Umbraco.Content(1186);

foreach (var item in lecturers.Children.Where("Visible").Random(6))
{
    <a href="@item.Url">
    <div class="frontpage lecturer box">
        <div class="left">
        <img src="@item.profilePicture" />
        </div>
        <div class="right">
            <strong>@item.Name</strong>
            <p>
            @if (@item.introToLecturer.ToString().Length > 130) {
                @Html.Raw(@item.introToLecturer.ToString().Substring(0, 130))<text>...</text>
            }else{
                @Html.Raw(@item.introToLecturer.ToString())
            }
            </p>
        </div>

            <div class="clear"></div>
    </div>
                </a>
}
<div style="text-align: center">
<a style="color: #FFF!important; margin-top: 20px;" class="button small white" href="/foredragsholdere">Alle foredragsholdere</a>
</div>

}

Sorry I'm not sure I understand what you're asking:

"Can we connect main folder ids and children ids."

These IDs can be viewed on the properties tab of each node. I think your issue with the profile picture is that you've used a type "Upload" - this should be a media picker. If you're hacking this stuff on live you might just want to create a new profile picture media field and set these all again.

HTH

Steve

Hi,

Yes , you are right. I changed media picker. now it works profile picture.

But description is displaying error.

hi,

This issue is that you're using Umbraco.Truncate - I thought you had a rich text editor - you don't.

Either swap the profile intro to use the rich text editor if you want editors to be able to enter rich text or change it back to how you had it.

The fact you're using Html.Raw makes me think you're putting html in there though!

@if (@item.introToLecturer.ToString().Length > 130) {
            @Html.Raw(@item.introToLecturer.ToString().Substring(0, 130))<text>...</text>
        }else{
            @Html.Raw(@item.introToLecturer.ToString())
        }

Hello Steve,

I have a little problem with profile intro. Why is dot coming in the down, its repeating two times.

see my sample picture

var lecturerIntro = lecturer.GetPropertyValue

I'm assuming you've changed the profile intro text to be a RTE type.

The Umbraco.Truncate adds a ... so you don't need the one in which will also be outside of the

from the Rich Text editor.

I suggest that if you have these issues in the future try little snippets and view the source of the page. It will help you understand what's happening.

Hi Steve,

Thank you very much for the all feed back. I take note of your comments and appreciate your help. I started to work in umbraco for three months back. I want to learn more about umbraco and become good at it . How can i do that. Can you give me suggestion.

Hi,

I think you should look to take the training courses - they are excellent!

https://umbraco.com/training/book-courses/ look for the Umbraco Fundamentals course

If you could mark this thread as solved that would be great
