Save a page reference field in a RepeaterMatrix

[Guy Verville]

Hi,

I must change via API a field called member_mx_images that includes an image and a page reference field called crm_products_sold. I have tried a lot of things but to no avail. I based my code along: https://processwire.com/api/fieldtypes/repeaters/

The code below shows $changed which is the repeated I must change. $products is an array of page IDs. 

			$changed = $p->member_mx_images->eq(array_key_exists($responseChanged['basename'],$indexMxArray));
				$products = explode(',',$responseChanged['products']);
				$changed->crm_products_sold = $products;
				$p->of(false);
				$changed->of(false);
				$changed->save();
				$p->save();

It's a false alert. I was compare the page field to itself.

However, to be able to update a page reference, you have to set it to null before. If not, the pages are added.

		$changed = $p->member_mx_images->eq(array_key_exists($responseChanged['basename'], $indexMxArray));
				$changed->of(false);
				$products = explode(',', $responseChanged['products']);
				$changed->crm_products_sold = null;
				$changed->crm_products_sold = $products;
				$changed->save();

And we do not need to save the page where the mx_field belongs to, because the variable $changed is in itself a page.
