I have a grid field with rows containing files uploaded. These grid entries are output on a standard page but I need to access the filetype of the files uploaded and this only appears to be available in a '{exp:file:entries}' tag pair. How can I access the file_id of the uploaded files in each row of the grid field in order to use a tag like {exp:file:entries file_id="grid-row-file-id"}{filetype}{/exp:file:entries}

Have you tried a variable pair and the {file_id} variable inside it? But, by this way, you already have access to the mime type, using the {mime_type} variable.

            <img src="{url}" height="{height}" width="{width}">
            <figcaption>mime type of file {file_id}: {mime_type}</figcaption>
  • That's brilliant - I didn't know you could use the grid row as a tag pair inside the main grid field tag pair! Sep 2, 2016 at 21:37
  • I've tried this in 3.4.3 and it doesn't work. Within a grid the opening {gallery:image} tag is rendered as the image URL. I don't think it's possible to get the meta data of the file when it's within a grid unfortunately. Nov 3, 2016 at 17:05
  • @CraigDuarte, this looks like a bug to me.

  • @RobsonSobral you're right, this was a bug with 3.4.3, fine in 3.4.4. Thanks! Nov 16, 2016 at 16:51
