Listing the available parameters
You can list the available parameters in ezpublish.legacy by using the ezpublish.legacy.keys property, as shown in the following example:
which will give a result similar to:
array 0 => string 'view_parameters' (length=15) 1 => string 'path' (length=4) 2 => string 'title_path' (length=10) 3 => string 'section_id' (length=10) 4 => string 'node_id' (length=7) 5 => string 'navigation_part' (length=15) 6 => string 'content_info' (length=12) 7 => string 'template_list' (length=13) 8 => string 'cache_ttl' (length=9) 9 => string 'is_default_navigation_part' (length=26) 10 => string 'css_files' (length=9) 11 => string 'js_files' (length=8) 12 => string 'css_files_configured' (length=20) 13 => string 'js_files_configured' (length=19)
Retrieving legacy information
Legacy information is accessible by using the ezpublish.legacy.get property, which will allow you to access all data contained in $module_result, from the legacy kernel.
This allows you to import information directly into twig templates. For more details please check the available examples on using the ezpublish.legacy.get property for retrieving persistent variables and assets.
As a usage example, if you want to access the legacy information related to 'content_info' you can do it, as shown in the following example:
The previous call will return the contents on the 'content_info' as an array, and if we dump it the result will be similar to the following:
array
'object_id' => string '57' (length=2)
'node_id' => string '2' (length=1)
'parent_node_id' => string '1' (length=1)
'class_id' => string '23' (length=2)

'remote_id' => string '8a9c9c761004866fb458d89910f52bee' (length=32)
'node_remote_id' => string 'f3e90596361e31d496d4026eb624c983' (length=32)
'offset' => boolean false
'viewmode' => string 'full' (length=4)
'navigation_part_identifier' => string 'ezcontentnavigationpart' (length=23)
'node_depth' => string '1' (length=1)
'url_alias' => string '' (length=0)
