I have struggled with this for a while. Can anyone help?

mustafans

I have two simple files

forms.php

<html>
   <head>   

      <title> Forms </title>      

   </head> 

   <body>     

      <form action ="process.php" method="POST">   

	      username: <input type = "text" 
		  name = "username" value =""> <br/>
          password: <input type = "password" 
		  name = "password" value =""> <br/> <br/>     

          <input type = "submit" name = "submit" value ="Submit"><br/>
      </form>

   </body>
</html>

and process.php

<html>
   <head>   

      <title> Form Processing </title>      

   </head>   

   <body> 
      <?php           

      $username = $_POST['username'];     

      $password = $_POST['password'];               

      echo "{$username}: {$password}";
      ?>		 
   </body>
</html>

When I run the forms.php using phpdev it works...

I submit the user name and password and then it gives me this error running the process.php

Notice: Undefined index:username in c:\xampp\My Php Files\process.php on line 7
Notice: Undefined index:password in c:\xampp\My Php Files\process.php on line 8

Can anyone please tell me what I am doing wrong?

Thanks

Worked OK for me on my PC.

Why am I getting the error?

jorgepinho

Hi, please try the following:

print_r($_POST);

this will give you whats inside the post

NogDog

It could possibly (though usually unlikely) be that your PHP configuration has something non-standard for the variables_order directive, which could cause $_POST to not be set. Or I suppose if you're running a really, really old version of PHP it would not be set (instead the deprecated $HTTP_POST_VARS array would be). You can get info on version and config settings via the phpinfo();

Hi Jorgepinho

<html>
<head>

<title> Form Processing </title>

</head>

<body>
<?php
print_r($POST);

$username = $POST['username'];

$password = $_POST['password'];

echo "{$username}: {$password}";
?>
</body>
</html>

After I ran the forms.php entered the username and password this is what I got

I got Array =>mustafans (username I entered).. that is it.. one line.

and then the same errors as before...

Why is it printing out when I am passing username?

Any suggestions?

jorgepinho

Yes, that is weird...

NogDog is right... you should see your PHP version and settings

In this particular case... you should use:

$username = $_POST['u'];

mustafans

The password is not getting through...

I do not know anything about the settings.,, what exactly do I change in the php.ini?

Any help would be apprecaited..

jorgepinho

On a blank page, write

<?php
phpinfo();
?>

Then you will see the PHP version

I sometimes use this rescue code, use this on process.php blank page:

This will show ALL VARIABLES, just search if the username and password are somewhere

NogDog

Try this in the form-handler:

echo "Raw POST data:<br />\n";
echo htmlspecialchars(file_get_contents("php://input"));

I'm curious to see if there is something malformed in that string that might point to where the problem is. (The fact that there was any $_POST value at all probably points to something other than the version/configuration issues I was referring to.)

mustafans

The version is 5.3.1

I tried the rescue code and the username and password are in the GET array instead of the POST...

Why is that..

Thanks very much for the suggestions

I changed the $POST to $GET in both the echo statements and it worked. I do not understand though. The forms php has a $POST command. The transfer is the array and the $GET command has all the arrays the way they should be.

That is why I love programming..

Mustafa

jorgepinho

did you change the forms.php code that you posted here ?

mustafans

Hi Nogdog

I tried the rawpost command like you said

Raw POST data:

username=mustafa&password

i entered the username mustafa

I still get Array => mustafa for print_r $_POST

If the form tag says method="post" then that should not be happening. Still sounds like something weird is going on somewhere between when you hit the submit button and the php script actually starts running -- I just don't know what to guess that it is.

No I did not

jorgepinho

Strange things require more strange things...

There are lots of spaces in the form

instead of: name = "username"

use: name="username"

tags dont close properly by XHTML rules

Again... is the posted forms.php code updated ?

NogDog

It feels like maybe there's some illegal, probably non-printing character in the field name. I might try retyping the HTML form tags to make sure they're "clean", though I don't have high hopes for that making a difference. 🙁

Here is the latest

Forms.php

<html>
<head>

<title> Forms </title>

</head>

<body>

<form action ="process.php" method="POST">

username: <input type = "text"
name = "username" value =""> <br/>
password: <input type = "password"
name = "password" value =""> <br/> <br/>

<input type = "submit" name = "submit" value ="Submit"><br/>
</form>

</body>
</html>

process.php

<html>
<head>

<title> Form Processing </title>

</head>

<body>

<pre>
<?php
print_r(get_defined_vars());
?>
</pre>
<?php

echo "Raw POST data:<br />\n";
echo htmlspecialchars(file_get_contents("php://input"));
print_r($POST);

$username = $GET['username'];

$password = $_GET['password'];

echo"<br/>";

echo "{$username}: {$password}";
?>
</body>
</html>

Typed

username mustafa
password 678901

When I change the process.php to

<html>
<head>

<title> Form Processing </title>

</head>

<body>

<pre>
<?php
print_r(get_defined_vars());
?>
</pre>
<?php

echo "Raw POST data:<br />\n";
echo htmlspecialchars(file_get_contents("php://input"));
print_r($POST);

$username = $POST['username'];

$password = $_POST['password'];

echo"<br/>";

echo "{$username}: {$password}";
?>
</body>
</html>

Everything else the same

Here is the result
