As the other guys suggested, you could
Change the Error Reporting Level
By running this code at the top of your script:
error_reporting(E_ALL ^ E_NOTICE)Or, it might be a better idea to actually check whether those variables were posted before you use them.
Quick and Dirty fix is to do this:
The @ sign will suppress any errors and return false in place of the string. Now that practice is generally frowned upon.
If you want a cleaner method, I would do this:
Then you’ll never have a error about missing indexes, and you can set the default values to whatever you like.
Good luck
