API

While calling the pagefield all context data values will be assigned as runtime values to the page object.

To prevent conflicts an underscore must be prepended to contexts field name.

Example:

$page->fieldname; // call the field to assign runtime values

// get first item of PageArray
$reference = $page->fieldname->first();
echo $reference->_text; // get the value of context field 'text' of the referenced page

// loop PageArray
foreach ($page->fieldname as $reference) {
	echo $reference->_text;
}

Multilanguage Context Fields

Multilanguage Fields are supported. Set setting: useLanguages=1

Limitations

• The usage of get() or find() with context data values is very limited:
  • no support for multilanguage fields
  • only equal sign operator allowed
  • no support for array values
• Values are lost after removing related page from the page field.
• some Inputfield classes are not supported.
