TYPO3 Core

I can't reproduce that. the markers are alwasys filled in the template, no need to define anything in TS. With TS you can just apply stdwrap stuff to the value.

Example I used

plugin.tx_felogin_pi1 {
userfields {
    zip {
    wrap = a|b
    }
}
}

and the marker ###FEUSER_ZIP###

which markers did you use and are those records also really filled?

I used ###FIRST_NAME### for the first name instead of ###FEUSER_FIRST_NAME### because the marker ###NAME### also works (but it is not in the marker list on top of the template), so I didn’t read the manual completely because of that. When using ###FEUSER_FIRST_NAME### it works.
