Generating page in different "mode"

[marcin]

Hello,

I'm working on simple newsletter module and I want to modify page source(different header, no navigation and sidebar) while sending email based on page.

I need one of these:

a) pass a variable to page(the same as isAjax works, eg. isNewsletter)

b) render page using different template file

and have no idea how to achieve one of above.

I'm also wondering whether it's possible to get JSON response in admin? Module method ___executeXXX() prints whole page.

Thanks, Marcin

Hello there!

Without knowing exactly how your module works, I can only throw in general ideas - hope they're of some help:

a) You could use a GET variable for this; example.com/example-page/?view=newsletter and then "if ($input->get->view == "newsletter") { ... }".

b) There are many solutions for this one. Simple way would be fetching the content of your newsletter page ($newsletterPage = $pages->get('/page-uri-or-whatever')) and then including a file with your alternative markup (in which you use $newsletterPage instead of $page) wherever you wish to render the newsletter. Another method would be to play around with actual template files; see this post by Soma for an example.

One slightly crude method to get JSON (or pretty much any other markup you need) out of a process module is to output it (echo, output buffering, whatever floats your boat) and then die() -- or exit() if you prefer it that way. There are cleaner ways to do this too, but hey -- it works

Hello, thank for your reply

Whole thread you mentioned, appeared to be very helpful, thanks a lot! It solved both:

a) $somePage->set('variableName', value)

b) $somePage->template->set('filename', 'differentTemplate.php');

You idea about returning JSON - pretty cool!

PW community is really awesome.

If the request comes in through ajax, ProcessWire will detect it and your Process module can just return the content (JSON or whatever) that you want in the ajax. Basically, you don't need to do anything other than load the page with ajax and you should get what you want.

@ryan, thanks for your reply. I'll try it.

Another question - is there some easy way to use PageSelect field? Module has it's own page in admin, so I probably can't easily add this kind of field to 'admin' template. The only thing I need is selected page ID.

Thanks!

Here's one way that you could do that from your module's getModuleConfigInputfields function:

public static function getModuleConfigInputfields(array $data) {
 $inputfields = new InputfieldWrapper();
 $name = 'my_page_select';
 if(!isset($data[$name])) $data[$name] = 0; 
 $f = wire('modules')->get('InputfieldPageListSelect');
 $f->attr('name', $name);
 $f->attr('value', $data[$name]); 
 $inputfields->add($f);
 return $inputfields;
}
