I Think i know the solution - but any expert solution would benefit Newbie php developers

Thanks

u dont know the solution, thats why u are here

i guess are trying to use action instead of 'action' (in quotes) or action doesn't exist at all
post ur codes let's see.

I recognize the error, but lemme go to the solution. You will only see it offline on your localhost almost all the time.
It is due to a setting in your php. You need to access your php.ini file. I suspect you are using wamp server.

There are 3 ways to solve it, a temporary way it to write:

Method 1: Temporary
<?php
error_reporting(0); //at the begining of your script(s)
echo $_GET['nairaland']; //will not generate errors
?>

Method 2: Temporary - put that isset around all your variables
<?php
echo isset($_GET['nairaland']); //will not generate errors
?>

Method 3: Permanent - the best method

The location of the php.ini vary for each of the servers, IIS, wamp, XAMP, Reactor. . . . . . . . . . . . . . . . , . . .
If you are using wamp, just click on the system tray icon, click on php, click on php.ini

search for error_reporting, then you will come to a line like this:

; - Show all errors, except for notices and coding standards warnings
;
;error_reporting = E_ALL & ~E_NOTICE
;
; - Show all errors, except for notices
;
;error_reporting = E_ALL & ~E_NOTICE | E_STRICT
;
; - Show only errors
;
;error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
;
; - Show all errors, except coding standards warnings
;
error_reporting = E_ALL


Notice that ; is used to comment, just comment out that E_ALL, and uncomment the error_reporting = E_ALL & ~E_NOTICE,
so that your config looks like this:


; - Show all errors, except for notices and coding standards warnings
;
error_reporting = E_ALL & ~E_NOTICE
;
; - Show all errors, except for notices
;
;error_reporting = E_ALL & ~E_NOTICE | E_STRICT
;
; - Show only errors
;
;error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
;
; - Show all errors, except coding standards warnings
;
;error_reporting = E_ALL


Then restart your server after saving that file. Dont forget to make a backup copy before you
make changes so that you do not scatter it.

If you are still in doubt, check php manual for error_reporting.

Thanks dhtml Method 3 solved my problem

Method one is the best in development environment. The reason is that disabling error reporting in PHP.ini file will give less opportunity to debug your code in your development environment. Instead of getting error where you have gone wrong you get a blank document. However, if you use method 3 in a life server that's ok.

That method 1 can be modified to - error_reporting(E_ALL ^ E_NOTICE);
so that it has same effect as method 3. And of course all the methods can work, but the best one is the 3rd one.
That is the setting with most online servers, at least all that i have worked with so far.
