AyKay47 Posted January 25, 2012 Share Posted January 25, 2012 you should be checking if the $_GET variable isset before setting its value into a variable. really, intval() isn't necessary since the value will automatically be converted Link to comment https://forums.phpfreaks.com/topic/255758-the-simplest-thing-in-the-world-fails-lol/#findComment-1311069 Share on other sites More sharing options...

scootstah Posted January 25, 2012 Share Posted January 25, 2012 Unless you are unsetting $_GET variables in main.php, the problem is most likely nginx.

Pikachu2000 Posted January 25, 2012 Share Posted January 25, 2012 Could something in an include()d file or function be overwriting the $_GET array?

Cobra23 Posted January 25, 2012 Share Posted January 25, 2012 PHP Notice: Undefined index: id in x.php Did you define the id in x.php file ? To me it sounds like the page that it is being sent to once executed, that is causing the problem. or maybe even the include file which is affecting it.

cybernet Posted January 25, 2012 Author Share Posted January 25, 2012 how can i defined it if not like this ? $id = intval($_GET['id']); i searched main.php and has no unset problems i even replace $id with $post_id still the same result Link to comment https://forums.phpfreaks.com/topic/255758-the-simplest-thing-in-the-world-fails-lol/#findComment-1311106 Share on other sites More sharing options...
scootstah Posted January 25, 2012 Share Posted January 25, 2012 The error is not because of $id, it is because of $_GET['id']. The error says that $_GET['id'] is undefined. Try commenting out the include and see if it works then.

spiderwell Posted January 25, 2012 Share Posted January 25, 2012 yup if you use $_GET or $_POST or $_SESSION to try and get a value for something that doesnt exist , you will get this error Link to comment https://forums.phpfreaks.com/topic/255758-the-simplest-thing-in-the-world-fails-lol/#findComment-1311121 Share on other sites More sharing options...
AyKay47 Posted January 25, 2012 Share Posted January 25, 2012 if the OP uses isset() as I have recommended, this will not be an issue. OP, as pika said, most likely something in your included file is overwriting the $_GET array. Try removing the required file for testing purposes and see if you still get the error.
