If you have the 4.0.6 version then look at
$HTTP_POST_VARS and $HTTP_GET_VARS.
If your version is over 4.1.x then you have
$POST and $GET collections.
A comon way to combine the Get And Post methods is this
$vars=array();
foreach($HTTP_GET_VARS as $key => $value)
{
$vars[$key]=$value;
}
foreach($HTTP_POST_VARS as $key => $value)
{
$vars[$key]=$value;
}
Now in the $vars array you have all data sended from the form,whatever was send by POST or GET method.
so supossed you have an <input type="text" name="testField">
you will get the value from the $vars in this way.
$testField_value=$vars['testField'];
Hope to help.
Bye.
