you can check if a variable is set by using the isset function for example
| Code: |
if (!isset($myvar))
{
print("not set')
}
else
{
print("set!");
}
|
the ! in front of isset means "isn't" in normal english you could just take it off and invert the messages

Put this at the top of your page:
error_reporting (E_ERROR | E_WARNING | E_PARSE);
or you can go into your php.ini file and turn off notices
for all php pages. :wink: |

both of those worked great.
I like to use both options. Turning off the error reporting seems to be better security over my code and sql database...
thank you both

its ideal to turn on all warnings in a developmen enviroment, but in a production enviroment, for security reasons, yo should turn it off
