[TYPO3-dev] Resolve prepend_tname

[Georg Ringer]

Hello,

I use prepend_tname=1 in TCA to select more than 1 table but is there a 
nice way to resolve this again?

So in a field is saved: "tx_table1_foo_1,tx_table2_foo_23,tx_table2_foo_17"
and I want something like an array
tx_table1_foo: 1
tx_table2_foo: 23,17

thanks
georg
