Get Image Path in Transformation

Hi,

How can I retrieve the path to an uploaded image/file in a document type?

I have a document type with a File -> Uploader -> Direct Uploader field, called 'NewsTeaser'. I am retrieving the contents of this field in a Transformation:

<img src="<%# Eval("NewsTeaser") %>" alt="<%# Eval("NewsTitle",true) %>" />

Eval("NewsTeaser") does not resolve to the path to the uploaded file - it just resolves to the GUID of the uploaded file.

I can't use GetImage("NewsTeaser"), because I need to customize the attributes of the rendered <img> tag.

What other options are available?

Hi Juraj,

Although those URLs work, they both seem way over the top to just get the URL of an attached file. That article specifies how to generate a link without a GUID, but I really don't care whether the GUID is visible or not. The second link requires creating an instance of the AttachmentInfo class after jumping through lots of hoops beforehand.

Is there a reason why Kentico's API doesn't just provide a simple .GetAttachmentUrl(attachmentGuid) method?

I could be wrong, but I would have thought that returning the URL of an attached file was a fairly common CMS function.

Hi,

In this cas you can use the methods mentioned by Jiveabillion or just look to the default transformation, e.g. for the CMS.File document type there are attachments transformations and you can use e.g.: GetImage, GetFileUrl, GetAttachmentUrl, in cas of images GetImage functions.

When editing a transformation, at the bottom there is a link to all available functions for transformations (/CMSHelp/index.html?newedit_transformation_methods.htm).

Best regards,

Certified Developer 8	Jiveabillion - 9/14/2012 3:00:08 PM RE:Get Image Path in Transformation I usually use K# and text templates where I just use this {%GetFileUrlByGuid(ColumnName,NodeAlias)%} in ASCX transformations, you can do this <%# GetFileUrl("NewsTeaser") %>
