[PHP] $_Request from 4.3 to v5.x

[Michael Purdy]

 
Folks

I am currently using 4.3.7.

I have a script which accepts three POSTed variables from a basic form.  Under 4.3.7 
the script
runs fine and the variables are successfully passed to the script.

I am testing 5.0 C3 and receive the following error 

PHP Notice: Undefined index: searchtype in c:\http\cgi\list7.php on line 13

<script language='php'> 
  $searchtype = $_REQUEST['searchtype'];  -- this is line 13
  $searchterm = $_REQUEST['searchterm'];
  $matchtype  = $_REQUEST['match'];

Any suggestions on the best way to access data input into a FORM in version 5.x would 
be most appreciated.

Mike
