Test if Page field is multiple or single

[Robin S]

I have several Page fields in my template, some are "multiple page" fields and some are "single page" fields.

When looping through my template fields I need to also foreach the multiple page fields. What is a good way to test for multiple vs single page fields?

Or if I know I want to loop through my Page fields is it better to set them all to dereference as PageArrays?

Not sure if I'm getting your question right, but why not simply check if the value of the field is an instance of PageArray:

if ($page->field_name instanceof PageArray) {
    // iterate
}

Thanks, that does the trick.
