<@POSTARGNAMES>
Description
Returns an array containing the names of all post arguments.
Post arguments are passed to Tango through forms. A form that has a method of POST returns the results of its fields through post arguments. <@POSTARGNAMES> provides a mechanism for identifying the names of all post arguments received in the current request.
The array returned has one column and n rows where there are n unique post arguments.
Example
The following returns all post argument names using the default array formatting:
<@ASSIGN NAME="mypostargs" VALUE="<@POSTARGNAMES>">
Note:
If multiple post arguments
with the same name are received, the name of the post argument is
listed only once.
