Hi, i need a script or a software to help me to update information on many turistic web portal. I try to explain! Now when my clients need to open and close the availability of their rooms of the hotels they need to login portal by portal and update them. Or if they want change the rate for a particular period they have to login in the portal 1, change the rates, close the portal 1, open the portal 2 and so on. What i need is a script that do all from one software (php or other). The clients update inside this script and automatically the script update all connected portal. Of course when i talk of portal i'm referring to [login to view URL] or lastminute or itwg or [login to view URL] Waiting for your offer
