How i get the current URL segment as constants - typo3

Question

it's possible to save the current URL in constants for used this in setup?
URL Example: example.com/de/site1
I need the URL segment: "/de/site2"
Part of my constants:
#--------------------------------------------------
# Site Config
siteConfig {
homePid = 2
footerNaviPid = 4
currentURL =
}
In the setup i build a onPager navi and need the currentURL segment there.
Part of my setup
#---------------------
# Make Sections for OnePager
lib.sectionContentNavi = HMENU
lib.sectionContentNavi {
wrap = |
#entryLevel = 1
special = directory
special.value = 2
#excludeUidList = 25
entryLevel = 1
1 = TMENU
1 {
expAll = 1
noBlur = 1
wrap = <ul>|</ul>
NO {
wrapItemAndSub = <li>|</li>
linkWrap =|
}
ACT = 1
ACT {
wrapItemAndSub = <li class="act">|</li>
linkWrap =|
}
}
2 = TMENU
2 {
expAll = 1
noBlur = 1
wrap = <ul>|</ul>
NO = 1
NO {
doNotLinkIt = 1
linkWrap = <li>|</li>
stdWrap >
stdWrap {
wrap = |
insertData = 1
cObject = TEXT
cObject {
field = nav_title // title
}
}
}
ACT = 1
ACT {
wrapItemAndSub = <li class="act">|</li>
linkWrap =|
}
}
}
A tip from you make me happy :-)

Answer 1

you cant get variable data in your typoscript constants.
you can use variables in your setup (something like GET, POST or ENV).
for easier (or multiple) usage you can store these values in register variables.
But you should not build a-tags in typoscript or fluid on your own.
Try to use typolink or f:link viewhelpers.
in this way you never need to access the current URL as you only link to a page uid (and maybe action paramters and record parameters) and TYPO3 resolves it to the correct path segments.
