I created a new website and implemented the same solution, but this time it doesn't work.
I'll try to explain:
now I need to compare at least 3 fields.
So, I created a recordset that should display the records that will have these 3 fields identical.
This is the recordset I use:
WHERE registrazioni.data_scontrino_reg = datascontrino AND registrazioni.ora_scontrino_reg=orascontrino AND registrazioni.minuti_scontrino_reg = minutiscontrino AND registrazioni.numero_scontrino_reg = numeroscontrino
All variables here are compared to the related $_POST variables (as TEXT).
The strange thing is that it works locally (on a qnap webserver that has php 5.5.38), but it doesn't online (PHP 5.6.38).
Online, the validation pass everytime.
Please note that all other fields will validate correctly.
What can I check to make it work?
