Try something like this to get an idea of how this works..

Assume that your form is described in the code below, and 'frm_process.php' is the script that processes it.

Code: Select all

echo "<FORM name = 'frm_vars' method = 'post' ";

echo " action = 'frm_process.php?get_x=" . $var1;

echo "&get_y=" . $var2 . "'>";

echo "<INPUT type = 'hidden' name = 'post_x' value = '" ;

echo $var1 . "'>";

echo "<INPUT type = 'hidden' name = 'post_y' value = '" ;

echo $var2 . "'>";

echo "<INPUT type = 'submit' value = 'Submit'>";

echo "</FORM>";




and a little bit of the script frm_process.php..

Code: Select all

if (isset($_POST['post_x'){

  echo "value of x from post is: " . $_POST['post_x'];

  }

if (isset($_POST['post_y'){

  echo "value of y from post is: " . $_POST['post_y'];

  }

if (isset($_GET['get_x'){

  echo "value of x from post is: " . $_POST['post_x'];

  }

if (isset($_GET['get_y'){

  echo "value of y from post is: " . $_POST['post_y'];

  }







That should get you started. POST values come from form elements, such as inputs, hidden, selects, text areas, text boxes, etc. GET values can come from forms wich have there method set to 'get', (which I never do..) but usually contain the querystring values.

Best of luck, hope this helps.
