Passing variables

I can't get the variable to pass to php in the following

-----------------------
in kform.htm I have (this form works ok)

<HTML>
<HEAD>
First Form
<?HEAD>
<BODY>

<FORM METHOD="POST" ACTION="kform1.php">
<P> First Name: <INPUT TYPE = "text" Name = "firstname SIZE = "20">
<P><P>

<INPUT TYPE="submit" VALUE="Send info">
<INPUT TYPE="reset">

</FORM>
</BODY>
</HTML>
------------------------------
in kform1.php , I have

<?php

$firstname = $_GET['firstname'];

echo "Hi, your first name is: $firstname" ;

?>

---------------------------
When I run this I get

Notice: Undefined index: firstname in C:\Program Files\BadBlue\PE\kform1.php on line 4
Hi, your first name is:

Hi

If your method of sending the form is POST, the way to access the variable is $_POST['firstname'] not $_GET['firstname']

try:

<?php

$firstname = $_POST['firstname'];

echo "Hi, your first name is: $firstname" ;

?>

Or you could argue why even create another variable ($firstname) use:

<?php

echo "Hi, your first name is: $_POST[firstname]" ;

?>
>>>>note the missing '' around $firstname because the variable is encased in double quotes

Try this:
a) on form kform.htm add an attribute NAME="submit" after input TYPE="submit" have a space in between.

b) on <INPUT TYPE="text" add the " after firstname:
NAME="firstname" SIZE="20">

c) on form kform1.php:

<?php
  $firstname = $_POST['firstname'];
  // This means if submit button is not click.
  if( !array_key_exits('submit', $_POST) || empty($firstname) )
  {
    print <<<_HERE;

    <FORM METHOD="POST" ACTION="kform1.php">
      <P>First Name: <INPUT TYPE="text" NAME="firstname" SIZE="20">
      </P> <P />
      <INPUT TYPE="submit" NAME="submit" VALUE="Send info">
      <INPUT TYPE="reset">
    </FORM>
_HERE;
  }
  else
  {
    echo "Hi, your first name is: $firstname";
  }
?>

Note: the word _HERE; should be at the leftmost side of your code to work.
Hope this helps.

yes, use the array $_POST instead of $_GET, so it's $_POST[firstname] instead of $_GET[firstname]

Need to download code?
