TYPO3 Realurl Configuration Category Page - typo3

Question

I have TYPO3 7.6.10.
I have tx_news.
I want to configure my page with news by category.
Now i have:
'newsCategoryConfiguration' => array(
array(
'GETvar' => 'tx_news_pi1[overwriteDemand][categories]',
'lookUpTable' => array(
'table' => 'sys_category',
'id_field' => 'uid',
'alias_field' => 'title',
'addWhereClause' => ' AND NOT deleted',
'useUniqueCache' => 1,
'useUniqueCache_conf' => array(
'strtolower' => 1,
'spaceCharacter' => '-'
)
)
)
),
It works and the result is:
/domain/page-With-List-Of-News-By-Category/Category
If have a sub category the result is:
/domain/-page-With-List-Of-News-By-Category/Category
Ho can i get:
/domain/page-With-List-Of-News-By-Category/Parent-Category/Sub-Category

Answer 1

Maybe there's a faster or better way. But if you won't find, try this and build it yourself using userfunc in that way:
'useUniqueCache_conf' => [
'strtolower' => 1,
'spaceCharacter' => '-',
'encodeTitle_userProc' => 'My\Ext\Hooks\News\RealUrlCategories->buildCategoryPath'
];
and the class something like:
class RealUrlCategories {
function buildCategoryPath($parameters) {
$categoriesPath = '';
// find category rootline
// you can find the uid somewhere in $parameters, then iterate for parent categories and read db for the titles to build final string
...
// return generated string like "Parent-Category/Sub-Category"
return $categoriesPath;
}
}

The problem is, that realURL parses the result of the userFunc with rawurlencode. So Parent-Category/Sub-Category would be transformed to Parent-Category%252FSub-Category.
You could return Parent-Category-Sub-Category. This would also be stored in the cache.
Also your UserFunc could return Parent-Category~~~Sub-Category and you replace the ~~~ with a / in a $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['realurl']['encodeSpURL_postProc'] hook, but the ~~~ will be stored in the cache.
You could also add another parameter like parent_category, but this optional parameter doesn't work in the fixesPostVars section because here the parameter is required and so if it is empty, you have an double slash //category in your URL.
Could you find any other solution beside to use the format parent-category-sub-category?
