Merge/combine two text fields

[sarah_hue]

Hi,

I've got three fields in a template page:

• name
• surname
• full name (hidden field)

Now I'd like "full name" to be a combination of "name" and "surname". There's no need to use javascript, since I only need the "full name" field later on for processing. Would be totally fine to populate "full name" once the page is saved. I don't have any experience with hooks, any hints how I could get the merging done?

Thanks

sarah

Great, thanks a lot!

Extra question: If I want to add "Name: " as extra text to the new combined field – how could I do this?

you can create an autoload module that adds this on save via a hook:

• look at site/modules/helloworld.module
• copy+rename it to eg addNameOnSave.module
• edit classname + content of getModuleInfo()
• install + test it - it should say "helloworld ..." after save

edit your init function:

public function init() {
    $this->pages->addHookAfter('saveReady', $this, 'saveactions');
}

remove the helloworld functions and add this one:

/**
 * do some actions on saving
 */
public function saveactions($event) {
    $page = $event->arguments('page');

    if($page->template == 'your_template') {
        $page->fullname = "Name: " . $page->forename . " " . $page->surname;
    }
}

not tested, hope i did not forget anything

If the use case is to put a label before the field in the page tree you can also use css (:before with "content").

or on frontend templates:

echo "Name: " . $page->fullname;

definitely depends on where you want to add "Name: "
