Passing a url to header image
Hi Morgan,
Looking for a pointer and advice on where to look. I am trying to build an app that shall allow users to post a url in a custom field. Once that URL is posted(and/or edited) i want to process it(as is the case with any gars module) and if it matches some logic, then i will call a image(thumbnail) and replace the header image with that thumb. So basically Custom Field -> New thread/edit thread -> Custom field URL entered -> Process the custom field -> If it matches with some logic, call thumbnail link -> Replace the header image field with the image thus called. I had a brief look and couldn't find any hook or call to get this done. Basically after processing a cusom module entry box, how do i call the header image field? Some pseudo code or where to look would be wonderful :) |
The closest thing to that would be this add-on.
