RE: [PHP] Undefined index

i usually get those annoying errors whenever i even do $foo = "bar"; if notice is on is it requiring just like in a class to verify the var first like var $foo ? -----Original Message----- From: caspar kennerdale [mailto:caspar@thetuckshop.com] Sent: Thursday, May 08, 2003 2:14 AM To: php-general@lists.php.net Subject: RE: [PHP] Undefined index This just checks if it is set or not, but I know it is not set. It seems to me that it is best to set it rather than cover up an error message. using this example I would need to have action set so that the error message does not appear when thwe page loads on default. (action is set whenever any of the other cases are requested such as "index.php?action =Test"). switch ($_GET['action']) { default: // action is not set by default so I get an error // $action = "blah"; at the top of the page does nothing break; case "Test": //action is set to "test" so no error message break; } cheers -----Original Message----- From: Adam Voigt [mailto:adam@cryptocomm.com] Sent: 07 May 2003 16:58 To: caspar kennerdale Cc: php-general@lists.php.net Subject: RE: [PHP] Undefined index If you mean like: switch($blah) { } And your getting the warning's about $blah, just do: if(is_set($blah)) { switch($blah) { } } On Wed, 2003-05-07 at 11:46, caspar kennerdale wrote: > Thanks that 'covers' up the error message, but is there no way to give the > index a value then when it is the default of a switch? > > > Cheers > > Caspar > > > Just at the top of your page, or in an include, put: > > error_reporting(E_ALL ^ E_NOTICE); > > (This is according to the error_reporting manual page). > > > On Wed, 2003-05-07 at 11:37, caspar kennerdale wrote: > > I have a basic switch defining the structure of my page.
