limitphp Posted July 11, 2009 Share Posted July 11, 2009 Notice: Undefined index: loginMode in C:\wamp\www\inc_login_script.php on line 2 I'm not sure what is wrong here. In the index.php file I have an include: include("inc_login_script.php"); In the inc_login_script.php on line 2 is this: $loginMode = $_POST['loginMode']; I just installed wamp server 5.2.9-2 Is there another setting I need to turn on?

mattal999 Posted July 11, 2009 Share Posted July 11, 2009 You should check if it is set first: <?php if(isset($_POST['loginMode']) && $_POST['loginMode'] !== "") { $loginMode = $_POST['loginMode']; } ?> Link to comment https://forums.phpfreaks.com/topic/165634-solved-undefined-index-error/#findComment-873718 Share on other sites More sharing options...
Mchl Posted July 11, 2009 Share Posted July 11, 2009 Nope. You need to check if the index 'loginMode' exists in $_POST array, before you try to assign its value to anything. if(isset($_POST['loginMode'])) { $loginMode = $_POST['loginMode']; } Or you can just disable reporting of E_NOTICE level error messages.

limitphp Posted July 11, 2009 Author Share Posted July 11, 2009 Is this a new error? I don't remember getting all these errors, several months ago when I had wamp server installed?

wildteen88 Posted July 11, 2009 Share Posted July 11, 2009 Is this a new error? I don't remember getting all these errors, several months ago when I had wamp server installed? Your previous installation most probably had a setting called display_errors disabled or the error_reporting level was set to ignore notices. Notices are not errors, these do not prevent your script from running however they are simple to correct.

limitphp Posted July 11, 2009 Author Share Posted July 11, 2009 Its actually giving me another : Notice: Undefined variable: s in C:\wamp\www\inc_login_script.php on line 5 on line 5 I have this: $salt = "®$s:<š1ašskj67^&&*&*"; It thinks I'm declaring s because there is a $ sign in front of it. Can you not have a dollar sign as part of a value in a variable?

wildteen88 Posted July 11, 2009 Share Posted July 11, 2009 Change the double quoes to single quotes. Link to comment https://forums.phpfreaks.com/topic/165634-solved-undefined-index-error/#findComment-873736 Share on other sites More sharing options...
Mchl Posted July 11, 2009 Share Posted July 11, 2009 That's because default error levels have changed in WampServer's recent version. Notices are not serious errors . They're rather indicating parts of your code, that might lead to unexpected behaviour. As I said, you can just disable these messages (look in php.ini for error_reporting). This will make your script work, but is not a recommended thing to do. The proper line of action is to correct your code, so that no notices are thrown. [edit] See? The actual value of $salt was not ®$s:<š1ašskj67^&&*&* but ®:<š1ašskj67^&&*&* Link to comment https://forums.phpfreaks.com/topic/165634-solved-undefined-index-error/#findComment-873737 Share on other sites More sharing options...
