[Solved] Looping through every field of a page

[Marcel Stäheli]

I have a car template that contains dozens of fields. The collection of cars is growing and now I have different configurations for the same car type. To save work and time I created a "general" car page for every car where I enter data that fits every car configuration. Both the general car page and the car configuration have the same template and identical fields.

The idea is that for every car I start with the general page and if a field is empty I get the data from the corresponding car configuration field.

Is there a way to loop through every field of a page? I don't want to write a compare function for every single field.

You can iterate over the fieldgroup property of the page's template.

Edit: perhaps starting with a copy of the general page and emptying/setting a few fields that need to be different might also be an option.

Thanks using the term fieldgroup I also found it in the new doc http://processwire.com/api/ref/page/ under the advanced section. I didn't check that part, my bad.

Surely this is the simplest approach, or maybe I am misunderstanding?

foreach($page->fields as $f) {
    echo $page->$f;
}
