How to inject variables into page templates from a custom Drupal module?

We have created a dedicated module for organizing and publishing our newsletter.

The problem I'm currently facing is and I'm new to Drupal module development and development, so it might just be a knowledge issue, not a Drupal issue - this is how to get each topic newsletter.

At this point, the URL structure of our newsletter will look like this:

/ newsletters / {newsletter-name} / {edition-name} / {issue-date}, which means that we can create template files in our theme using filenames like page-newsletters- {newsletter-name} - {edition- name} .tpl.php which is great. The only problem I am having is that all content ends up in the $ content variable of the theme. I would like it to turn out as different variables (so that I can, inside the theme, place certain content in certain areas.)

Is there a suitable way to do this?

Edit: To answer some questions: the problem is node (there are release, release and news nodes) and the path is set using hook_menu with wildcards and a router.

The best answer I could find is to add a check inside the phptemplate_preprocess_page to send the vars back to the module and update them.

Same:

function phptemplate_preprocess_page(&$vars) {
    if (module_exists('test_module')) {
        _test_module_injector($vars);
    }
}


then in my test_module.module I created this function:

function _test_module_injector(&$vars) {
    $vars[] = call_to_other_functions_to_load_vars();
}

It seemed to work. I wish there was a way to do this without touching the theme's template.php file, but otherwise it works well.

If the documentation for the template preprocess functions were improved, Drupal would be much more accessible - as you need to gather information from many different explanations. One place to start:

but if you take the time to work with the tutorial below, you will find that you can do most of the things:

This is an old post and the OP's problems seem to have been resolved.

However, just for others discovering this via Google (or otherwise):

Use Devel Themer to step through the $ content variable and find what you need to pull out.

There are a bunch of Devel / Themer docs / tuts out there, but using it is pretty straightforward. Note, however, that some things there must be disinfected before being printed in the subject.

Suggesting to show node as a view and then change view templates sounds pretty crazy, although it will work.
