confiforms: third form to control two other form entry

[laurent]

I have form1 and form2 where each have fieldl1 and field2. Form3 have only one field. Each time a value is entered in form1/field1 or form2/field1 value is copied in form3/field1 with an IFFFT rule. My goal is to be sure that an entry in Form1/field1 not already exist in form2/field1  or entry in Fomr2/field1 not already exist in form1. To do that I use Form3 with uniquesense fonction rule. That work ! if the current entry already existe in form1 or form2 I can show a validation message but it doesn't stop the entry record....

If someone understand me, can you help me to stop record when entry already existe in form3    

Thanks

Hi

You can use the "onError" handler to remove the record from the form if the IFTTT to copy it into the "form3" fails

See what I mean

Hi

In my idea I want avoid record in form1 or form2 if value exist in form3. Is it possible to use field rule to seek value in form3. In that mean validation message appear when you enter value in field, not when you click on register buron ?

This is exactly what this demo does... It will remove the record from form1/form2 if it finds out that it exists in the form3
