but not in online server, cause online servers switch off this feature in php to notice for undefined variables. But in localhost or xampp configuration this is not switched off so we see this error. Undefined Index Undefined index actually means you http://www.webfulcreations.com/php-error-notice-undefined-index/ have a variable or constant in your php file which is not defined or assigned any value means that is empty variable. Suppose you are saving posted value from a form into a variable called user_email like http://forum.kohanaframework.org/discussion/4474/how-to-remove-errors-like-undefined-index-/p1 this $user_email = $_POST[‘user_email'];. When you submit form you will not see this error cause that time our $user_email variable will hold a string which can be empty or having anything in it. But when you access undefined index page directly via url and by not submitting form then there is not way php can assign value to $user_email variable that's why php will produce a notice for you saying this is an undefined index. I do not suggest switching off Notices via PHP configuration. How to remove Notice: Undefined Index As a php developer i faced this problem several times but i always used only 2 methods to handle these notices. undefined index error Put your variable defining when its getting value from something else in if() statement. Like this if(isset($_POST)) { $user_email = $_POST[‘user_email']; } This statement will only run if POST array is set if not then this will not run and will not produce any notice. As POST is also not set why not error? cause we are just checking it with isset function within if condition. When i have several variables in 1 file and i want to switch off these notices for that file but not for other files then i put this in top of my php document. //to disable Notice errors on System. Notices removal. error_reporting( error_reporting() & ~E_NOTICE ); This will not only disable undefined index notices but all other notices php want to give you as well. What is PHP isset function?

Support How to remove errors like "undefined index" ? thomasg December 2009 Hi! Is it possible to hide errors like undefined index or offsets ? Without Kohana and this error reporting : error_reporting = E_ALL & ~E_NOTICE & ~E_DEPRECATED I don't get any problem with a code like this : $test = array('one'=>'one','two'=>'two'); echo $test['one']; echo $test['three']; If i copy into a kohana page, I get an error page : Undefined index: three (By the way, I would prefer a real PHP error, with Kohana, impossible to know on which line error ocurred !) Thx ! shadowhand December 2009 I would prefer a real PHP error, with Kohana, impossible to know on which line error ocurred! That's simply not true... Look: Changing the error_reporting settings will, in fact, change which errors are displayed. You can find them in index.php. arctic December 2009 Undefined indexes are not really anything to worry about and you can edit your error_reporting like shadowhand said. It could make you a better programmer though. yogal January 2010 You could also use either the Arr class, built into kohana3 -> http://kerkness.ca/wiki/doku.php?id=working_with_arrays_in_kohana or php function, array_key_exists(); Both will check if a given key exists in an array and return a boolean value. Arr::get will do more than that, you can specify a default value, in case a key doesn't exist. So the code would look like that: $test = array('one'=>'one','two'=>'two'); echo $test['one']; if (array_key_exists('three', $test)) { echo $test['three']; } It might be too much of a hassle, but thats the way i determine what action to take when processing a form: (I have buttons like Save, Apply and Cancel) Because when pressing a submit button only one key will be present: if (array_key_exists('save', $
