I am reading Todd Duell's book on FM 13 API for PHP .. On page 56 he says
"The FileMaker API for PHP uses the RecordID to find records, not the auto enter serial number feature."
I have a live solution which is using WebDirect which I now want to add CWP using PHP.
All my relationships are configured using the auto enter serial number for primary keys .
I am wondering if I have to change all those relationships to use RecordId from now on , to make the solution ready for use with PHP API ?
Will that not break all my layouts , scripts , value lists etc ?
I don't mind changing all the occurrences but what if I break my solution and data is corrupted ? ...
Need some advice ..
