Name of the HTTP method by which the parameters were sent:
"POST" - Sending parameters from the HTML form
"GET" - Sending parameters as a part of the required new page
String that contains values of individual elements from the HTML form. This string has the form, for example "a=13&b=xyz"
. It means that "a"
has the value "13"
has the value "xyz"
By the Pm.HTTPGetFormValue method it is possible to separate individual values from this string (see example).
The event fires after the PmWeb.onNewRequest event and before creating the answer to the client (before loading and modifying the file pEvent.FilePath and before the PmWebDir.onPageModify event).
The event fires only when the client that sends the data, has the access right WebWrite.

<form action="main.htm" method="POST">
<input type="text" name="V1" value="22"/>
<input type="submit" value="Send to the server"/>
