Requirements

silverstripe/framework >=3.7
zauberfisch/silverstripe-serialized-dataobject >=3.0
zauberfisch/silverstripe-namespace-templates >=1.0

Installation

composer require "zauberfisch/silverstripe-page-builder"
Optional: install suggested packages
- composer require "zauberfisch/silverstripe-page-builder-basic-blocks"
rebuild manifest (flush)

Unfortunately a bug in SilverStripe current breaks the HTMLEditorField file management inside a sub controller within the CMS, to work around this bug the following work around is required:

In your project .htaccess replace RewriteRule .* framework/main.php?url=%1 [QSA] with RewriteRule .* index.php?url=%1 [QSA] and create an index.php file (you can replace the default SilverStripe file if your server supports mod_rewrite) with the following content:

  <?php
  
  if (isset($_GET['ID'])) {
      # redirect as workaround for inset File dialog in the PageBuilder
      # which is broken because ?ID=<$fileID> is mistaken for a Page ID by LeftAndMain
      # lets replace ID with FileID which is then converted back in PageBuilder
      $match = true;
      $url = $_GET['url'];
      foreach(['PageBuilder', 'EditorToolbar', 'viewfile'] as $str) {
          if (strpos($url, $str) === FALSE) {
              $match = false;
              break;
          }
      }
      if ($match) {
          $id = $_GET['ID'];
          $_GET['url'] = str_replace(['?ID=','&ID='],['?FileID=','&FileID='], $url);
          $_REQUEST['FileID'] = $id;
          $_GET['FileID'] = $id;
          unset($_REQUEST['ID']);
          unset($_GET['ID']);
      }
  }
  
  chdir('framework');
  require 'framework/main.php';

Documentation

Add the PageBuilder DB Field and FormField to any DataObject, for example Page:

class Page extends SiteTree {
    private static $db = [
        'PageBuilder' => \zauberfisch\PageBuilder\Model\DBField::class,
    ];
    
    public function getCMSFields() {
        $fields = parent::getCMSFields();
        $fields->addFieldsToTab('Root.Main', [
            new \zauberfisch\PageBuilder\Form\Field('PageBuilder', $this->fieldLabel('PageBuilder')),
        ]);
        return $fields;
    }
}

Now, in your template, you can access $PageBuilder and output the content:

<% if $PageBuilder %>
    <div class="my-content-blocks">
        $PageBuilder.Value
    </div>
<% end_if %>

See docs/example.md for example project files with some basic frontend.

However, in the bare installation this module does not provide any content types. It just provides the abstract classes and form fields.
Just like with SilverStripe DataObjects it is up to the individual developer and other modules to define the desired data types.
A good starting point with some basic block types can be found in the basic blocks module.

Documentation for creating custom blocks has not been written yet, please refer to the basic blocks module, they should serve as good examples.

Known Issues

When using this module with Translatable, the language selection for the TreeDropdownField in the HTMLEditorField insert link dialog does not work
GridFields within the dialog might not work
Duplicating a Record will duplicate blocks, but ContentBlocks are still linked by their ID, therefore two objects now share the same ContentElement
Obsolete ContentElement DataObjects are not deleted (eg if a Text Block is created, but the page is never saved)
The Edit Dialog is not ideal for nested content that also requires a dialog (HTMLEditor, GridField, ...)
