PDLs and Addons

It seems to be ignoring the mod_example.pdl file in custom addons.

Based on the addons in the official addon repository, the pdl file for Mod_Example.php should be mod_example.pdl, right?

And if you want to set a different php template, you would add [template]doubleleft[/template] to the PDL file at the top. Correct?

Do I have to do something special to get it to use the addon's pdl file?

by editing theme php / pdl files changes do not always appear right away

try to delete the files in

/store/[data]/smarty3/compiled/

and see if this makes a difference

Thanks. That didn't work. I think the problem is something else.

If I put the pdl file into the redbasic theme (or other active theme), then it works. But when the pdl file is in the addon, it ignores it.

I know that you can put a pdl file in an addon since the articles, cards, and wiki addons all use pdl files within the addon itself.

For some reason, I can't get it to work in my custom addon.

I think we figured out the problem.

You have to follow a certain undocumented convention to get it to work.

Creating an addon with only one module seems to be pretty straightforward. Everything has the same name. But when you have a module that uses multiple submodules, it is less obvious what needs to be done.

One of my developers reverse engineered the core code controlling addons, and I think we figured out what we need to do.

When we are done, we will have a working addon that includes comments documenting various parts of the addon.

Okay, small setback. Apparently the pdl only applies to the main module, and not to any other modules within the addon.

This is a problem.

And looking through the addons, it looks like we are the only person who ever tried to use a pdl file on multiple modules within the same addon.

It might be the case that the core does not support this. O.o

@Scott's Code Journal You could always hook the alter_pdl hook, which get's whatever layout the system has decided for you in the layout key in the array it receives. You could just replace that with the content of the pdl file you want to use. This will be the pdl that is passed to Comanche.

It's a bit of a cludge, but I think it should work.

@Harald Eilertsen Thank you.

I think we finally figured it out. Apparently there is a load_pdl hook.

Hook::register('load_pdl', 'addon/custompage/custompage.php', 'custompage_load_pdl');

And you have to load it for every submodule in the addon.
