Method HttpMessage() :getParameter() Foundation
Gets the value of a HTTP parameter by its name.
Syntax
:getParameter( <cName> ) --> cValue | NIL
Parameters
<nName>
A character string with the name of the parameter.
Return
:getParameter() returns a character string with the value of the parameter. If the parameter is empty, return is the empty string (""). For undefined parameters, :setParameter() returns NIL.
Description
The method :getParameter() gets the value of a HTTP parameter given its name. For parameters which appear several times in the query string (multiple parameter values), only the value of the first parameter is returned. The method :getParameters() can be used for retrieving multiple parameter values.
HTTP parameters are transferred as part of the query string. The methods :addParameter(), :delParameter(), :getParameter(), :getParameters() and their respective :set..() counterparts allow direct and easy manipulation of this part of the HTTP query string. Use the method :getQueryString() for obtaining a reference to the complete string.
