Submit lib.nav to postUserFunc - typo3

Question

I would like to generate a main json with all content elements and navigation.
For this I generate a UserFunc
[globalString = GP:json=1]
lib.header >
# include jsonProcessor.php
includeLibs.jsonTools = /mobile-api.php
config.disableAllHeaderCode = 1
config.doctype = none
# set json header
config.additionalHeaders = Content-type:application/json
# keep typo3 from "tidying up" -> perfectly valid json
config.xhtml_cleaning = 0
# json encoder
page.stdWrap.postUserFunc = generateJson->pageToJson
[global]
Is it possible to submit in my ts the lib.nav to the postUserFunc?
Thanks

Answer 1

Assumed lib.nav is a TS object you defined before the postUserFunc, you can pass this objects definition to your function as follows
# json encoder
page.stdWrap.postUserFunc = generateJson->pageToJson
page.stdWrap.postUserFunc.libNav < lib.nav
This definition will be available in the second parameter of the method generateJson->pageToJson
class generateJson {
function pageToJson($content, $config) {
// analyse $config['libNav'] for the object type
///and $config['libNav.'] for his definition
}
}
In case you want to render this menu you must call tslib_cObj->cObjGetSingle() explicitely.
$local_cObj = t3lib_div::makeInstance('tslib_cObj');
$myNaviCode = $local_cObj->getObjGetsingle($config['libNav'],$config['libNav.']);
