Remove pages from field type page

[jan 17]

Hi there,

I have a template with a field type page. Now I try to remove one of the pages inside this field.

I think I'm kind of blind – it won't do what I want it do

foreach ($myPage->pageField as $pageInField) {
    if( /* condition to find page to remove */ ) {
        $myPage->pageField->remove($pageInField);
        break;     
    }
}

Thank you!!!

Something like this could probably work....

$x = $pages->get(1412);//necessarily verbose - could have done this in foreach
foreach ($x->myPageField as $f) {

   if ($f->name == 'example') {//set your condition
         $x->of(false);
         $x->myPageField->remove($f);
         $x->save();
   }
}

Thank you very much!! This is the solution.

I have a PageField that holds a single page.  I've been trying to find the proper way to unset it, I've seen an example of using "unset" but that doesn't feel right, or very processwire-ish.

Right now, I'm using

$facility->region_page = new NullPage();

But this also, just doesn't feel right but appears to work.

Is there a best practice for unsetting a pagefield?

@bracketfire -

this should work:

$facility->region_page = '';
