Gallery field - dev info and creating templates

At first lets discover the current situation problem.

We have a concept that all logic parameters are in parameters and all display parameters are in template parameters. This lead us to need to make field template parameters. So you can see them only after you have chosen the field template. But we have decided that it is tooooooo much(good). It means that template parameters are mixed with logic parameters in the field parameters.

Should I by-pass the build-in display modes with a field override?

If you make template you can by-pass.

How are files stored (physically and in DB)? Which structure do uploaded files have? How to access them?

Every upload is registered in #__js_res_files with record_id field. So you can simply get all of them by query. But you do not have to. $this->value contain list of files with all needed information.

I guess, I have to do another PHP and SQL course. ;-)

Would like to see some reference or examples in knowledgebase, like you did for API and templates.

That is to wide field off application. I need example user case and more specific questions. Question like "HOw to fork with files?" are subject to small book.

How to check gallery field if it is empty?

i.e. If no images, than output default image or maybe custom html/link/message etc..

Be sure that the field is selected to output at the desired mode...

Example --> if you want to display it in a list template make sure the "Display in Intro" is checked on the field level.

Then check if there is content in the field .. (check the value (database column content) or result (generated output based on selected output template) )

Example:

<?php if(isset($item->fields_by_id[24]->result) && any additional condition if needed ):?>

 put here what you want to display if the field contains something

<?php endif;?>
