show_html.pl

Description

Show_html.pl is a HFPM module that reports the value of form fields and environmental variables in an HTML format.

Usage

show_html.pl {$fld | fld |%envvar} in the pipeline.

Usage Explanation

The fields and environmental variables given are as arguments to the program and the non-null ones are displayed back to the user in an HTML format. If none are given as arguments, then a whitespace-separated list of arguments are taken from the "_show_vals" field.

A '%' prefix indicates the argument is an environmental variable and a '$' prefix means a form field argument, which is the default. In addition, a field or environmental variable pseudo-name of "all" refers to all fields or environmental variables except those that are null or whose name begins with an underscore ("_").

The field "_title" is used as the title for the HTML page produced.

Examples

"show_html.pl $username comments %HTTP_USER_AGENT" on the pipeline: This returns something like this.
"show_html.pl" on the pipeline, "$all %all _title" in the field "_show_vals", and "Your comments" in the field "_title": This returns something like this.

Other Notes

The current version number is 1.0.

This module should work on any platform with a perl version 5 and CGI FPI implementation.

This module shouldn't be used more than once in the pipeline or used with another module that returns something to the user.
