[pmwiki-users] Form with specific php validation not returning or retaining previous entrys

[John Bowling]

I have a form in pmwiki and created my own validation php to insert the 
data into a pmcal calendar by date, and to email to myself. That part 
works well.

The problem lies in data entry errors, where the php detect the problem 
and notifies the user. It cannot return to the page where the form is, 
and if the back button is used, it erases all previous entries.

How can I make it do both of them?

Thanks
John
