Undefined index error

[cactus]

Hi,

 

I'm trying to create a cms and keep getting an undefined index:action error message.

I tried to use isset but then it just threw out a different error.

The section of code that is causing the errors is:

 

if ( $_GET['action'] != "login" && $_GET['action'] != "logout" && !$_SESSION['username'] ){ //ITS SHOWING 2 ERRORS WITH ACTION ON THIS LINE

  login();

  exit;

}

 

switch ( $_GET['action'] ) {  //IT ALSO HAS AN ERROR FOR ACTION ON THIS LINE

  case 'login':

    login();

    break;

  case 'logout':

    logout();

    break;

 

I would really appreciate the help as it's been annoying me and i'm having a mental blog.

Thanks in advance.

Hi,

 

try to use the isset function to check the index is defined or not! Are you sure the 'action' index is always exists?  Debug your code with print_r($_GET) to check indexes...

I'm pretty new to PHP so I'm not entirely sure what you mean. Although I did try the isset function and it just threw out a different error message.

Thanks for the reply.

you could try more brackets:

if (( $_GET['action'] != "login") && ($_GET['action'] != "logout") && (!$_SESSION['username'])){

Hi Ken,

 

The other error message was:

 

Parse error: syntax error, unexpected T_IS_NOT_EQUAL, expecting ',' or ')'

 

Thanks for the help.
