HELP Cannot figure very simple stupid question out.

rbaron · Aug 22, 2003

This is an extremely newbie question but I cannot figure out why this does not work. I have two forms one html that allows the user to enter a value in val1. The user submit and it goes to the second form calculate.php.
That form is supposed to display the value of the calculate_form.html. It does not, and I have tried about two thousand variations. I am stuck and apparently struck stupid. Any help would be greatly appreciated.

Here is the form and hence the problem. I checked other posts and found that the register_globals is set to on. I also see that the form method of php is set to GET. I tried that as well and although I could see the get results in the url I could not get it to display.

calculate_form.html

<HTML>
<HEAD>
<TITLE>New Page 1</TITLE>
</HEAD>
<BODY>
<FORM METHOD="POST" ACTION="calculate.php">
<P>Value 1: <INPUT TYPE="text" NAME="val1" SIZE=10></P>
<P><INPUT TYPE="submit" NAME="submit" VALUE="Calculate"></P>
</FORM>
</BODY>
</HTML>
----------------------------------------------------------
calcualte.php

<?php
$result=($_POST[val1]);
?>

<HTML>
<HEAD>
<TITLE></TITLE>
</HEAD>
<BODY>
<?php
echo $result;
?>

</BODY>
</HTML>

Have you tried:

<?php
$result=$_POST['val1'];
?>

?

Just tried that method with the same results. No information is displayed. I changed the METHOD to $GET with the code you supplied and same result. Although the get method does list this in the url address

http://www.hubbardohio.net/calculate.php?val1=1&submit=Calculate

Which is correct.

Here was the syntax that I used.

<?php
$result=$_GET['val1'];
?>

<HTML>
<HEAD>
<TITLE></TITLE>
</HEAD>
<BODY>
<?php
echo $result;
?>

</BODY>
</HTML>

No, since you're using a POST-method form, it's got to be $_POST.

Unless, of course, your version of PHP is older than 4.1.0. In which case you should be referencing $HTTP_POST_VARS instead of $_POST.

I tried both $POST and $GET with the same result. I see you reference PHP version I am using 4.2.3. I thought $POST was the correct syntax but when I apply it it does not display the value of val1.

I am knew to PHP but not to programming and this is driving me nuts.

I don't know what it could be. I'm running PHP 4.3.2 on a LAMP box, and the original code you posted worked perfectly.

Have you tried $HTTP_POST_VARS['val1']?

Have you tried performing: print_r($_POST);
?

These did not work either. There must be some problem with my PHP. I will contact my ISP and see if they can help. Thank your for the assistance.
