panel.page.update

You can block updates for pages. This will switch all form fields to readonly fields and hide the save button.

Target Data

ui

$this->target()->page()

action

$this->target()->page()
$this->target()->data()

Example

<?php

// site/roles/editor.php
return [
  'name'        => 'Editor',
  'default'     => false,
  'permissions' => [
    '*'                 => true,
    'panel.page.update' => false
  ]
];

Allow updates for a specific template

<?php

// site/roles/editor.php
return [
  'name'        => 'Project Editor',
  'default'     => false,
  'permissions' => [
    '*'                 => true,
    'panel.page.update' => function() {
      return $this->target()->page()->template() === 'project';
    }
  ]
];

Allow updates for a specific language

<?php

// site/roles/editor.php
return [
  'name'        => 'German Editor',
  'default'     => false,
  'permissions' => [
    '*'                 => true,
    'panel.page.update' => function() {
      return $this->language()->code() === 'de';
    }
  ]
];

Intercept update data

<?php

// site/roles/editor.php
return [
  'name'        => 'German Editor',
  'default'     => false,
  'permissions' => [
    '*'                 => true,
    'panel.page.update' => function() {

      if($this->state() === 'ui') {
        // keep the form active
        return true;
      }

      if($this->target()->data()['title'] !== 'Keep me!') {
        return 'You are not allowed to make this update';
      }

      return true;

    }
  ]
];
