Notice: Undefined variable
Hi All,
I'm getting the following Notice in my php output: -
Notice: Undefined variable: error in /var/www/html/inventoryupd ate.php on line 133
Notice: Undefined variable: message in /var/www/html/inventoryupd ate.php on line 139
The code that this relates to is as follows: -
If you ignore it the output of the php for $error and $message variables work when the form is used accordingly based on the following php which is linked via an include_once statement.
Thanks J

Apologies ... I wrongly just grabbed lines 133 - 139 forgetting it would be re-jigged when placed into the code box. The full code is here ...

Do a search on that code for $error
What do you find?
The first time $error is encountered is on line 133 in an if statement - which is going to cause the error.
Where is the confusion here?
Where is $error being set?

Hi Ray,
Thanks as always for the back-ground information ... now I also "understand" why this is in-correct.
I've plenty more to do ... so no doubt will be back soon.
Thanks J.

First rule: the compiler is never wrong. If the compiler says the variable is not defined then it is not defined. Chances are you have a number of code paths through your script and in one of them you are using the value $error where it has not been set yet.
This is the sort of problem
Open in new window
In the above if $value <> 1 then you will get the error you are seeing.To fix this the correct way of doing the above code is
Open in new window
