Cache : array of page IDs to ignore

The CMS Questions
1

Hi,
The doc says we can provide a list of page IDs to be ignored from the cache. I’m looking for the correct synthax to make the cache work on multiple pages inside these lines :

'cache' => [
      'pages' => [
          'active' => true,
          'ignore' => function ($page) {
            return $page->title()->value() === 'Do not cache me';
          }
      ]
  ]

I tried many ways to write it like

'ignore' => function ($page) {
            return $page->title()->value() === ['Accueil', 'Panier'];
          }

or even

'ignore' => ['Accueil', 'Panier'];

Finally I don’t find the correct way to make it works.

With an array, you cannot use a simple === operator, but have to use in_array()

'ignore' => function ($page) {
    return in_array( $page->title()->value(), ['Accueil', 'Panier']);
}

Untested, but this should work:

'cache' => [
  'pages' => [
    'active' => true,
    'ignore' => function ($page) {
      return in_array($page->id(), ['accueil', 'panier']);
    }
  ]
]

Note that the ID is always lowercase. If you are checking for page titles instead, use in_array($page->title(), ['Accueil', 'Panier']).

@texnixe You beat me to it :laughing:

Also note that to make this work, you should make sure to use a property that cannot be changed. So add something like

options: 
  changeSlug: false
  changeTitle: false

depending on what property you use.

@sebastiangreger But we agree, so @Oziris can be super sure to trust our answers now :wink:
