Create output_html_with_http_headers function to contain the "print $query ->header(-type => guesstype...),..." call. This is in preparation for non-HTML output (e.g., text/xml) and charset conversion before output in the future. Created C4/Interface/CGI/Template.pm to hold convenience functions specific to the CGI interface using HTML::Template Modified moremembers.pl to make the "sex" field localizable for languages where M and F doesn't make sense

|
C4::CGI::Output - Convenience functions for handling outputting HTML pages
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use C4::CGI::Output;
|
|
|
|
print $query->header(-type => C4::CGI::Output::gettype($output)), $output;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The functions in this module peek into a piece of HTML and return strings
|
|
related to the (guessed) charset.

|

|
&guesscharset($output)
|
|
|
|
"Guesses" the charset from the some HTML that would be output.
|
|
|
|
C<$output> is the HTML page to be output. If it contains a META tag
|
|
with a Content-Type, the tag will be scanned for a language code.
|
|
This code is returned if it is found; undef is returned otherwise.
|
|
|
|
This function only does sloppy guessing; it will be confused by
|
|
unexpected things like SGML comments. What it basically does is to
|
|
grab something that looks like a META tag and scan it.

&output_html_with_http_headers($query, $cookie, $html)
|

Outputs the HTML page $html with the appropriate HTTP headers,
|
|
with the authentication cookie $cookie and a Content-Type that
|
|
corresponds to the HTML page $html.
