!HELP! Undefined Index

[code_god]

Please help I have this issue for a while and don't know how to fix the problem. I get an error message saying that there is an undefined index on line 9 and also line 10.

 

I have no idea how to solve this so please help 

tim.php

Undefined index just means that you are asking for an array key that doesn't exist, or isn't defined.

That should also show up as a notice, and not an error.

 

<?php
{
$name = (isset($_POST['username'])) ? $_POST['username'] : NULL;
$password = (isset($_POST['password'])) ? md5 ($_POST['password']) : NULL;
echo $password;
//if(isset($_POST['notify_box'])){ $notify = $POST['notify_box'];}
}

The code snippet I gave you did fix the problem.  It checks to see if the index exists, if it does it assigns it, if it doesn't it assigns a null value.

No mate it hasn't worked I still have the notice.

 

Here they are:

 

Notice: Undefined index: username in f:\easyphp1-8\www\tim.php on line 9

Notice: Undefined index: password in f:\easyphp1-8\www\tim.php on line 10

undefined x 1366

Post your script of line 5 through line 12.

[code_god]

</form>

 

<?php

{

$name = ($_POST['username']);

$password = md5 ($_POST['password']);

echo $password;

if(isset($_POST['notify_box'])){ $notify = $POST['notify_box'];}

[jcbones]

That doesn't look anything like the code snippet I gave you.  Here it is again.

 

{
$name = (isset($_POST['username'])) ? $_POST['username'] : NULL;
$password = (isset($_POST['password'])) ? md5 ($_POST['password']) : NULL;
echo $password;
//if(isset($_POST['notify_box'])){ $notify = $POST['notify_box'];}
}

[code_god]

I have tried that and I still get the Notices

well your issue stands in the area

echo "<br>";

if(!isset($_GET['r']))
{
	echo "<script language=\"javascript\">
	<!--
	document.location=\"$PHP_SELF?r=1&width=\"+screen.width+\"&Height=\"+screen.Height;
	//-->
	</script>";
}
else
{

	//CODE TO BE DISPLAYED IF RESOLUTION IS DETECTED
	if(isset($_GET['width']) && isset($_GET['Height']))
	{
		echo $_GET['Height']." x ". $_GET['width'];
	}
	else
	{
		echo "resolution not detected";
	}

}
?>

where are you defining "r" 

[desjardins2010]

if I remove that section of code the error is gone script acts as should... 

[jcbones]

Here is your script running on my server: with the suggested fix.

	Name : 
	Password : 
	 
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.22+ (KHTML, like Gecko) Chromium/17.0.963.56 Chrome/17.0.963.56 Safari/535.22+ 
undefined x 1920

PS, the issue in this case isn't $_GET['r'] because OP is already testing if it is set.

I re-read the code that you sent me and missed a couple of brackets out and it works now Cheers!!
