Blueprint to create select from Page Collection

How do I get a list of child pages of /teams to create an admin blueprint for a user to create an event? (pick Home team and Visiting team for a game)

I can create a 'select' with options

YAML

team-select-away:
  type: select
  label: Visiting Team
  options:
    option1: "Team 1"
    option2: "Team 2"

I want the options to be populated from all child pages that exist under /teams.

YAML

team-select-home:
  type: select
  label: Home Team
  options:
    - ''
  data-options@:

I can populate options from:

TXT

  data-options@: '\Grav\Common\Page\Pages::types'

I cannot populate options from:

TXT

  data-options@: ['\Grav\Common\Page\Pages::children', '/teams']
  data-options@: ['\Grav\Common\Page\Pages::getCollection', '/teams']
  data-options@: 
    '@page.children': '/teams'

I know the field works as I've set it up. I just can't seem to figure out the YAML syntax for 'get all children of /teams and populate them in a select list.'

@storm, The function being called must be a static function. The ones that are failing aren't.

Try:

$ bin/gpm install devtools
$ bin/plugin devtools new-plugin
Follow wizard and run $ composer update in folder of new plugin.
Let's say you called the plugin "teams".

Add the following function to file /user/plugins/teams/teams.php:

PHP

public static function teams(): array
{
/** @var Grav */
$grav = Grav::instance();
$grav['admin']->enablePages();

/** @var Page */
$teamsPage = $grav['pages']->find('/teams');

$children = [];
foreach ($teamsPage->children() as $team) {
  $children[] = $team->title();
}

return $children;
}

In your blueprint use

TXT

data-options@: '\Grav\Plugin\TeamsPlugin::teams'

@pamtbaau's reply is correct.

Wish I'd known Discourse is still active a few days ago when I wasted a lot of time looking for this same problem's answer and posted a question on a closed issue before finding an answer on Stack Overflow of all places. Is this forum indexed by search engines?

$grav['admin']->enablePages(); seems to be the magic key here. I would love to see this documented as an official solution in the Collections chapter of Learn, but don't feel qualified to volunteer as I don't understand it properly. It seems to me it's a reasonably common requirement.

@hughbris,

Out of sight, out of mind... ;-)

Yes, contrary to Discord, Discourse is being indexed by Google. Try hughbris site:discourse.getgrav.org on Google.

Maybe my problem is that I never search with Google :/ My wondering was only based on this post not coming up near the top when I looked for it. Did not investigate further, thanks anyway!
