Re: Re: CGI fails to urlencode & chars in outbound url's

You also may use CGI.pm's own escape function:

This is probably irrelevant to this discussion. The a() function is being used, which already escapes its arguments. Or at least CGI.pm version 2.752 does.

2;0 juerd@ouranos:~$ perl -MCGI=a -le'print a({ -href => "&&&" }, "asd
+f")'
<a href="&amp;&amp;&amp;">asdf</a>

But that's exactly what nobody wants, as the & of & is treated as parameter delimiter. `#!/usr/bin/perl -w use strict; use CGI; my $q = new CGI; print $q->header; print "<pre>\n"; print $_, "=", $q->param($_), "\n" for $q->param; print "\n</pre>\n";` [download] prints `foo=bar amp= baz=` [download] for `http://electra.igd.fhg.de/cgi-bin/test3.pl?foo=bar&baz` [download] but it should print `foo=bar&baz` [download] You need to use CGI::escape or URI::Escape but not CGI::escapeHTML. Update: Just for completeness: a() calls CGI::Util::make_attributes on each attribute, the latter calls CGI::Util::simple_escape for escaping ("&"->"&" and some others). CGI::Util::escape does something different (see my last post). alex pleiner <alex@zeitform.de> zeitform Internet Dienste	[reply] [d/l] [select]

#!/usr/bin/perl -w
use strict;
use CGI;
my $q = new CGI;
print $q->header;
print "<pre>\n";
print $_, "=", $q->param($_), "\n" for $q->param;
print "\n</pre>\n";
