Error submitting a from to PHP file?

abduljan

Hi all,

I have got a form which has got 3 text boxes and a submit button. The textboxes are:

txtname, txtemail, txtcomment

I submit this form by post method to getfrom.php file. I get the values like bellow:

<html>

<head>

<title>getvalues.php</title>

</head>

<body>

<?php
print "Your name is: $txtname ";
print "Your Email is: $txtemail ";
print "Your comment is: $txtcomment ";
?>

</body>

</html>

but it raises the error:

Notice: Undefined variable: txtname in C:\Inetpub\iissamples\php\first.php on line 12
Your name is:

Notice: Undefined variable: txtemail in C:\Inetpub\iissamples\php\first.php on line 13
Your Email is:

Notice: Undefined variable: txtcomment in C:\Inetpub\iissamples\php\first.php on line 14
Your comment is:

How can i pass the values of the textboxes to the php file then?

Hi!
You try to access there fields by calling their names but that is a failure. A special array takes care of the variables sent by POST method - the HTTP_POST_VARS (mind the capital letters). The you call the variable like a part of this array like this:

HTTP_POST_VARS["textfield1"].
If you use the GET method you can access them as you have done

That's all.

I don't know about the print function, but I think it requires parentheses around everything.

You can use the echo statement instead of the print function, like this:

<?php
echo "Your name is: $txtname ";
echo "Your Email is: $txtemail ";
echo "Your comment is: $txtcomment ";
?>

It works with the "post" method or "get". Give it a try.

hi,
I think you are right. I was missing something. I did like this rather but still raise error:

<html>

<head>

<title>getvalues.php</title>

</head>

<body>

<?php
$name=HTTP_POST_VARS["txtname"];
$email=HTTP_POST_VARS["txtemail"];
$comment=HTTP_POST_VARS["txtcomment"];

print "Your name is:  $name <br>";
print "Your Email is:  $email <br>";
print "Your comment is: $comment <br>";

</body>

</html>

Error message is:

Parse error: parse error, unexpected '[' in C:\Inetpub\iissamples\php\first.php on line 12

what else can go wrong?

Hi Abdul!
The error you're getting is may be some of those errors that PHP gives from time to time. I don't know what is the reason but I'll try to figure it out and will post a message back.

Sorry for not helping!
