API manipulation of Reference Page Field

[Schwab]

Is there a way to manipulate Reference Page Fields by the API?

I want users to add page reference items to the field, but found no information about it.

The other option I see is using Repeaters instead and save the page id of the referenced page in the repeater field. But creating or deleting the Reference Page field would be nicer. There is no automatic update of the id in the repeater, in case of a change to the referenced page.

Any solutions?

Cheers Simon

Have a read here about WireArrays. A multi page field returns a PageArray (which is derived from a WireArray).

http://processwire.com/api/ref/page-array/

http://processwire.com/api/ref/page-array/add/

http://processwire.com/api/ref/wire-array/

http://processwire.com/api/ref/wire-array/add/

Examples

// examples
$someOtherPage = $pages->get(1234);
$page->your_page_field = $someOtherPage;// @note: not sure it works in all contexts
$page->your_page_field->add($someOtherPage);
$page->your_page_field->add(1234);
// Add multiple pages
$page->your_page_field->add($pages->find("template=basic-page"));

Thanks kongondo

It is indeed as simple. Both version work actually.

$p = $pages->get(1234);
$p->of(false);
$p->page_reference_field->add(1111); // add another page by id
$p->save();

Found out the solution myself, thank you!

Nevermind I was thinking this problem from a wrong standpoint.

Hey I have a pagereference array added to user template.

I'm trying to add multiple pages to it via api. I have all the page ids to add as an array.

I can't add multiple pages to the page reference array. I've tried with: 

$userToCreate->projectReferences->add(wire()->pages->find('id=' . implode ('|', $data->projects), ['findAll' => true]));
$userToCreate->projectReferences = wire()->pages->find('id=' . implode ('|', $data->projects), ['findAll' => true]));
//however this works
$userToCreate->organisationReference = wire()->pages->get('id=' . $data->organisationId, ['findOne' => true]);

I'm adding 'findAll' because of my custom authentication for templates. And using wire() because this doesn't happen in a template file

How I can add multiple pages to this pagereference array?

Thanks for your help!

@VeiJari,

Works fine for me here with the code I posted above. 

<?php namespace ProcessWire;

// get current user
$user->of(false);
// $user->project_references = $someOtherPage;// @note: not sure it works in all contexts
// $user->project_references->add(1654);
$user->project_references->add($pages->find("template=basic-page,parent=1651"));
// $user->save();
$user->save('project_references');// saving just the multipage reference field

What is $userToCreate?
