Encoding spaces in CGI form data

fepifanio has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

Got I'm in troubles with an html form. I'm getting some data from a mysql DDBB, so finally showing it in a form to let the user edit the fields.

I recived the data in hex format, so by means the tr function I'm writing white spaces instead the + symbol, so if theres writed: hello+ferran, the translation should be hello ferran: tr/+/ /. but... what if the user really wants to insert the simbol +?

Any idea?

Many thanks MONKS

Enter CGI: `use CGI; my $q = CGI->new(); my $user_input = $q->param( 'user_input' );` [download] -- edan	[reply] [d/l]

That's what the CGI::unescape function for: `use CGI; print CGI::unescape("hello+ferran%21"), $/; __END__` [download] prints `hello, ferran!` [download]	[reply] [d/l] [select]

Special characters other than spaces are replaced with their UTF-8 value in hex, each byte preceeded by a '%': '+' becomes '%2B', '%' becomes '%25', etc. `$cgi->param()` and `$cgi->params()` will properly unescape everything for you.	[reply] [d/l] [select]
