Listing the available p= arameters

Example on retrieving the available parameters under ezpublish.legacy

=20
{{ dump(ezpublish.legacy.keys()) }}
=20

which will give a result similar to:

=20
array 0 =3D> string 'view_parameters' (length=3D15) 1 =3D> string 'path' (length=3D4) 2 =3D> string 'title_path' (length=3D10) 3 =3D> string 'section_id' (length=3D10) 4 =3D> string 'node_id' (length=3D7) 5 =3D> string 'navigation_part' (length=3D15) 6 =3D> string 'content_info' (length=3D12) 7 =3D> string 'template_list' (length=3D13) 8 =3D> string 'cache_ttl' (length=3D9) 9 =3D> string 'is_default_navigation_part' (length=3D26) 10 =3D> string 'css_files' (length=3D9) 11 =3D> string 'js_files' (length=3D8) 12 =3D> string 'css_files_configured' (length=3D20) 13 =3D> string 'js_files_configured' (length=3D19)

Retrieving legacy informa= tion

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 ezpubli= sh.legacy.get property for retrieving persiste= nt variables and assets.

As a usage exampl= e, if you want to access the legacy information related to 'content_info' y= ou can do it, as shown in the following example:

Example on accessing 'content_info' under ezpublish.legacy

=20
{{ ezpublish.legacy.get('content_info') }}
=20

The previous call will return the contents on the 'content_info' as an <= code>array, and if we dump it the result will be simila= r to the following:

=20
array 'object_id' =3D> string '57' (length=3D2) 'node_id' =3D> string '2' (length=3D1) 'parent_node_id' =3D> string '1' (length=3D1) 'class_id' =3D> string '23' (length=3D2) 'class_identifier' =3D> string 'landing_page' (length=3D12) 'remote_id' =3D> string '8a9c9c761004866fb458d89910f52bee' (length=3D3= 2) 'node_remote_id' =3D> string 'f3e90596361e31d496d4026eb624c983' (lengt= h=3D32) 'offset' =3D> boolean false 'viewmode' =3D> string 'full' (length=3D4) 'navigation_part_identifier' =3D> string 'ezcontentnavigationpart' (le= ngth=3D23) 'node_depth' =3D> string '1' (length=3D1) 'url_alias' =3D> string '' (length=3D0) 'current_language' =3D> string 'eng-GB' (length=3D6) 'language_mask' =3D> string '3' (length=3D1) 'main_node_id' =3D> string '2' (length=3D1) 'main_node_url_alias' =3D> boolean false 'persistent_variable' =3D>=20 array 'css_files' =3D>=20 array 0 =3D> string 'video.css' (length=3D9) 'js_files' =3D>=20 array 0 =3D> string 'video.js' (length=3D8) 'class_group' =3D> boolean false 'state' =3D>=20 array 2 =3D> string '1' (length=3D1) 'state_identifier' =3D>=20 array 0 =3D> string 'ez_lock/not_locked' (length=3D18) 'parent_class_id' =3D> string '1' (length=3D1) 'parent_class_identifier' =3D> string 'folder' (length=3D6) 'parent_node_remote_id' =3D> string '629709ba256fe317c3ddcee35453a96a'= (length=3D32) 'parent_object_remote_id' =3D> string 'e5c9db64baadb82ab8db54f0e2192ec= 3' (length=3D32)
