NAME

OpenPlugin::Param - Retrieve GET/POST/other values sent by client with a request

SYNOPSIS

 $OP = OpenPlugin->new();

 @params = $OP->param->get_incoming();

 $param  = $OP->param->get_incoming('param');

DESCRIPTION

The Param plugin offers an interface to retrieve parameters sent from the browser to the server.

METHODS

get_incoming( [ $fieldname ] )

get( [ $fieldname ] )

Called with no parameters, get_incoming() returns a list containing the names of each parameter sent to the server.

Called with one parameter, get_incoming returns value(s) for $fieldname. Call in list context to return multiple values for $fieldname.

set_incoming( $fieldname = $value )>

Set the value of an incoming parameter. This is typically called internally when the server receives parameters by the browser. However, sometimes developers find it useful to be able to modify this value, perhaps in order to do sanity checking on the information sent from the user.

The $value parameter can be a reference to a hash, if there are multiple values for a particular field.

BUGS

None known.
