Doesn't seem to recive data

[Sami]

This code:

<?phpif($_POST["pass"]&&$_POST["username"]) {$status=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["username"]."&password=".$_POST["pass"]);$user=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["username"]."&password=".$_POST["pass"]."&c=username");$mission=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["pass"]."&password=".$_POST["pass"]."&c=mission");}if($user){setcookie("nick",$user);setcookie("mission",$mission);// header("location:chat");}else{if($ok=="Fail!") {// header("location:chat?action=errormsg"); }else {// header("location:chat?action=errormsg_offline"); }}echo "Debugging: " . $status;?>

Are returning this:

Debugging: 

But it's supposed to return this:

Debugging: ok

or this:

Debugging: Fail!

Anybody know what I've done wrong?

There might be an error in login.php. What happens if you load it directly from your address bar? Should it output something if there is no POST data? That would let you test it, anyway.

It will probably be a good idea to also make sure all errors messages are enabled. Maybe it's not even loading the page.

Yeah, I've loaded it from my adress bar, and it's working just fine.

How?

[Sami]

I tough I should get more help...

[jeffman]

If you add these lines to the top of your script, you will get reports of runtime errors:

error_reporting(E_ALL);ini_set('display_errors', 1);

This technique will not alert you to syntax errors, because the lines will never execute. To detect syntax (parsing) errors, you might want to use a shell script.

$user=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["username"]."&password=".$_POST["pass"]."&c=username")

most probably $user is not assighining a value there...i think it is not entering in your first if block..you may echo the $_POST data to check that what the values are coming.

[jeffman]

You really should change this line:if($_POST["pass"]&&$_POST["username"]) {to this:if(isset($_POST['pass']) && isset($_POST['username']) ) {If either of those values has not been sent by the form, you will generate the first notice. So maybe you tested the documents by leaving the password field empty?$user has not been initialized. This means that if the first condition fails, this line:if($user){will be attempting to access a variable that does not exist. The same is true here:if($ok=="Fail!")I don't see any line in your code that sets the value of $ok to anything. This could be a serious problem.In looks like $status is not echoing. Be aware that if file_get_contents cannot open your file, it will return FALSE. PHP echoes the value of TRUE as 1. You might think it would echo the value of FALSE as 0, but instead it echoes nothing. So something could be wrong with the address you are passing to file_get_contentsIn this case, however, if $_POST["pass"] has no value, or is not set, $status does not get set, and that will cause your final notice.You should try to var_dump($_POST) at the top of your script to see if it contains what it should contain. Make sure that 'pass' and 'username' are named fields in your POST form.

<?phpif(isset($_POST['pass']) && isset($_POST['username']) ) {$status=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["username"]."&password=".$_POST["pass"]);$user=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["username"]."&password=".$_POST["pass"]."&c=username");$mission=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["pass"]."&password=".$_POST["pass"]."&c=mission");}if(isset($status)){setcookie("nick",$user);setcookie("mission",$mission);// header("location:chat");}else{if($status=="Fail!") {// header("location:chat?action=errormsg"); }else {// header("location:chat?action=errormsg_offline"); }}echo "<p>Debugging: " . $status . "</p>";?>

Still not working...

[jeffman]

Add these temporary statements to your code. (Don't add the statements that are identical to your existing statements)

<?phperror_reporting(E_ALL);ini_set('display_errors', 1);var_dump($_POST); // just to see; please copy the text and show us.if(isset($_POST['pass']) && isset($_POST['username']) ) {$status=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["username"]."&password=".$_POST["pass"]);if ($status) {   echo $status;}else {   echo '$status has no value';}exit; // just terminate execution here so you can see what is happening. Please show us what get's echoed.

If this goes on much longer we'll need to see the contents of login.php

[thescientist]

you missed one of the biggest piece's of advice DD gave you

You should try to var_dump($_POST) at the top of your script to see if it contains what it should contain. Make sure that 'pass' and 'username' are named fields in your POST form.

making sure the form is even submitting properly should be the first step in debugging in these kinds of situations.

Parse error: syntax error, unexpected $end in /var/www/htl/retro/include/log_in.php on line 49 Huh? The PHP end tag is at line 49 - nothing else.

[jeffman]

That usually mean a (parenthesis) or a {brace} did not get closed somewhere in the middle of the script. It might have happened when you added the code I gave you.BTW, if you are getting reports of parse errors, you do not need to turn on error reporting at the top of your script. It must already be on, or you are using the shell script I linked you to.

[Sami]

That file is just an included file that's being included if the cookie "nick" and the GET "action=dologin", so I added the error reporting to the file the users are accessing.

[Sami]

Just changed the code a little bit:

<?phpif(isset($_POST['pass']) && isset($_POST['username']) ) {$status=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["username"]."&password=".$_POST["pass"]);$user=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["username"]."&password=".$_POST["pass"]."&c=username");$mission=file_get_contents("http://192.168.0.197/login.php?username=".$_POST["pass"]."&password=".$_POST["pass"]."&c=mission");}if(isset($status)){setcookie("nick",$user);setcookie("mission",$mission);// header("location:chat");}else{if($status=="Fail!") {// header("location:chat?action=errormsg"); }else {// header("location:chat?action=errormsg_offline"); }}if(!isset($status)){$status="<i>\$status</i> isn't set";}echo "<p>Debugging: " . $status . "</p>";print_r($_POST);?>

This is it's result:

Notice: Undefined variable: status in /var/www/htl/retro/include/log_in.php on line 15<p>Debugging: <i>$status</i> isn't set</p>Array(    [username] => Sami    [password] => *************)

[thescientist]

I'm guessing you should be looking for $_POST['password']?

[Sami]

Maybe I should
