$Web IsIndex Parm Lstr

<section begin="desc" />Value of URL parameter to longstring<section end="desc" />

$Web_IsIndex_Parm_Lstr retrieves the value of a URL parameter as a longstring.

Since isindex fields are more commonly called "URL parameters," you may want to use the synonym for this $function, $Web_URL_Parm_Lstr.

Syntax

<section begin="syntax" /> %STRING = $Web_IsIndex_Parm_Lstr( name, occurrence ) <section end="syntax" />

$Web_IsIndex_Parm_Lstr takes two arguments and returns a longstring (or null for any error condition).

name	The name of the URL parameter, returned by $Web_IsIndex_Name. This is a required argument if occurrence is not specified; otherwise it is optional.
occurrence	The occurrence number of a URL parameter, or the occurrence number of the URL parameter matching name, if name is specified. This is an optional argument if name is specified; otherwise it is required.

If you have a URL that looks like:

http://myhost.edu/whatever?war=peace&love=hate

The following will retrieve the values of the War andLove fields into longstrings called %war and%love.

%war = $web_form_parm_lstr('WAR') %love = $web_form_parm_lstr('LOVE')

$Web_IsIndex_Parm_Lstr works much like $WEB_ISINDEX_PARM, except for the following:

• It can return more than 255 bytes of data into a longstring.
• It causes request cancellation if the result would be truncated, either on assignment to the target STRING %variable, or as input to a STRING $function argument or subroutine parameter.
• It does not have position and length arguments (arguments 3 and 4).

$Web_IsIndex_Parm_Lstr is only available in Sirius Mods Version 6.7 and later.

For more information about longstrings, see the Sirius Functions Reference Manual.
