Hi Andreas,

This should be a good starting point for you. With this Razor code you will list the files from a folder. First go to the developer section, create an new partial view macro file. Use this code in the file.

@inherits Umbraco.Web.Macros.PartialViewMacroPage

@*

    Macro to display a series of files from a folder.


    How it works:

        - Confirm the macro parameter has been passed in with a value

        - Loop through all the file Id's passed in (might be a single item, might be many)

        - Display any individual files, as well as any folders of images

    Macro Parameters To Create, for this macro to work:

    Alias:folderId     Name:Select folder with files    Type:Single Media Picker

*@


@{ var mediaId = Model.MacroParameters["folderId"]; }
    @if (folderId != null){

    @* Get all the media item associated with the id passed in *@
    var media = Umbraco.Media(folderId);
    var selection = media.Children("File");

    if (selection.Any()){
        <ul>
            @foreach (var item in selection){
                <li>
                    <a href="@item.umbracoFile"">
                        @item.Name
                    </a>
                </li>

            }
        </ul>

    }

}

You need to add the paramter in the developer section macro. Go to the developer section open up the macro folder, and choose the macro that contains your file that you just created. Then add the param  Alias:folderId Name:Select folder with files Type:Single Media Picker

When you insert the file to your template, then you will have to choose the folder where you have the pdf files.

Hope this helps, if you have further questions don't hesitate to ask again.

Nice, thx alot, but how do i get the macro to be available in the richtexteditor?

Hi Andreas,

You can enable the macro to be available in the richtext editor, by going to the developer section in the macro folder. Click on the macro that you just have created. In there you can set some different settings, one of them is Use in rich text editor, and if you are using Umbraco 7.2 it´s Use in rich text editor and the grid.

In there you can also set if the macro should be cached.

Hope this helps,

/Dennis

Thx, but i got an error, 

Error loading Partial View script

Hi Andreas,

Did you press the add button and then the save button, after you added the parameter to your macro.

Hope this helps,

/Dennis

yes this the code,

How it works:

    - Confirm the macro parameter has been passed in with a value

    - Loop through all the file Id's passed in (might be a single item, might be many)

    - Display any individual files, as well as any folders of images

Macro Parameters To Create, for this macro to work:

Alias:folderId     Name:Select folder with files    Type:Single Media Picker

*@

@{ var mediaId = Model.MacroParameters["folderId"]; } @if (folderId != null){

@* Get all the media item associated with the id passed in *@
var media = Umbraco.Media(folderId);
var selection = media.Children("File");

if (selection.Any()){
    <ul>
        @foreach (var item in selection){
            <li>
                <a href="@item.umbracoFile"">
                    @item.Name
                </a>
            </li>

        }
    </ul>

}

}

Hi Andreas,

I have just updated the code there was some small issues to the first one that I posted. Try to see if this also works for you.

}

nopp, still error though

Hi Andreas,

Okay what you could try to do to find out what is give you the error is, try to add the code step by step, to see where it breaks.

So first if you have this code in your file does it still error though

@inheritsUmbraco.Web.Macros.PartialViewMacroPage

@*

    Macro to display a series of files from a folder.


    How it works:

        -Confirm the macro parameter has been passed inwith a value

        -Loop through all the file Id's passed in (might be a single item, might be many)

        - Display any individual files, as well as any folders of images

    Macro Parameters To Create, for this macro to work:

    Alias:folderId     Name:Select folder with files    Type:Single Media Picker

*@


@{     
    var folderId = Model.MacroParameters["folderId"]; }

    @* Get all the media item associated with the id passed in *@
    var media = Umbraco.Media(folderId);
    var selection = media.Children;

    if (selection.Any()){

    }

}

And on this way take it step by step to see where it´s breaks.

Hope this helps,

/Dennis

still get the error :-(

Hi Andreas,

Okay that a bit wired. But if you go the the developer section partial view folder, and try to create a new file, then in the dropdown for code snippets then choose List Images from Media Folder

I have just tried this code at it works for me on Umbraco 7.2.2 And I only get the file type "File" out instead of images. I have also tried in the Grid layout and it works fine there too with this code.

What exact version of Umbraco are you using? Then I will see if I can reproduce what you are experience tomorrow on the same version like you are using.

Hope this helps,

/Dennis

I did everything from the begining again and still got the error.

iam running Umbraco version 7.1.8 assembly: 1.0.5394.16131

Hi Andreas

Could you try setting up the code based on the standard macro "List Images From Media Folder" and then try commenting out the statements to see what line is causing the error by uncommenting it line by line? The {)'s pairs should of course not be uncommented if you need to test a statement inside it.

Also I would like to know if the /App_Data/Logs file reveals any details about the error message? It should contain information about the macro you're using and mention what is the cause of the error.

In regards to your folder where you're storing the PDF...is that a standard Folder or have you defined your own folder document type, which you use in the media archive?

Looking forward to hearing from you.

hi, i have done that but still got the error, but i will try row by row now.

i got this in the log

Error loading Partial View (file: ~/Views/MacroPartials/ListPdf.cshtml).

Hi Andreas

Ok...perhaps you have some obscured items in the media section? But let's see how the line by line approach works out.

/Jan

hi, i got it to generate correct now, but when i press publish the macro disaperas, got any clue why?

Hi Andreas

Do you mind sharing the working code? :)

Hmm, not sure why it happens - I remember seeing other people experience this issue as well. I suspect it's a bug in that particular version. Might be worth checking the issue tracker at http://issues.umbraco.org/issues

/Jan

of course, here it is

@inherits Umbraco.Web.Macros.PartialViewMacroPage

@*

    Macro Parameters To Create, for this macro to work:

    Alias:mediaId     Name:Media Folder ID    Type:Single Media Picker

*@

@if (Model.MacroParameters["mediaId"] != null)

{

     @* Get the media folder as a dynamic node *@

    var mediaFolder = Umbraco.Media(Model.MacroParameters["mediaId"]);

    if (mediaFolder.Children.Any())

    {

        <ul>

            @* for each item in children of the selected media folder *@

            @foreach (var mediaItem in mediaFolder.Children)

            {

                <li><a href="@mediaItem.umbracoFile">@mediaItem.Name<a/></li>

            }

        </ul>

    }

}

My problem was that it was called mediaId and not folderId, and the it worked i was also needed to change the

<li><a href="@mediaItem.umbracoFile">@mediaItem.Name<a/></li> 

I couldn´t find any issue report on this though.

But the simple solution was that there was a "blank" in the name of the macro

is working on a reply...
