Thumbnails, channel_short_name and channel fields

Question

I have a image "thumbnail" field in multiple channels, ie: "news_thumbnail" "projects_thumbnail" "editorials_thumbnail"

With these images, I use EE's resizing feature to crop multiple sizes of the image.

I'm attempting to display the images using the following:

{{channel_short_code}_thumbnail}{path}_frontpage/{filename}.{extension}{/{channel_short_code_thumbnail}

This outputs to

{news_thumbnail}{path}_frontpage/{filename}.{extension}{/{news_thumbnail}

The {path} {filename} and {extension} variables aren't being processed properly.

However if I hardcode the channel field and use:

{news_thumbnail}{path}_frontpage/{filename}.{extension}{/{news_thumbnail}

{path},{filename} and {extension} are parsed to their proper values, and the image is displayed properly.

Any idea how to get this working properly?

Answer 1

You're trying to use the value of one variable (i.e., {channel_short_name}) to determine the key of another variable located at the same level of processing (i.e., {news_thumbnail}), which won't work.

I'd suggest using preload_replace variables instead, since they are parsed before any module tags are processed:

{preload_replace:current_channel="news"}

{exp:channel:entries channel="{current_channel}"}
    {{current_channel}_thumbnail}{path}_frontpage/{filename}.{extension}{/{current_channel}_thumbnail}
{/exp:channel:entries}
