Re: How do you pass a variable that contains a % character in it to the RPG program

I think that encode() in CGIDEV2 is an HTML encoding procedure rather than an a URL encoding procedure (and a pretty lightweight one at that).

I think CGIDEV2 has an encode() function you'd want to pass the input through...

You need to encode it when you create the url so that

.Program.pgm?mode=view&key=freight%&id=k3

is encoded as

.Program.pgm?mode=view&key=freight%25&id=k3

I understand this part, however, I pass 3 parameters example:



.Program.pgm?mode=view&key=freight%&id=k3



This is a CGIDEV2 program.



The program reads mode correctly but it gets confused with key and ID,
which it sees as 1 field. I see the value for key = freight%#@$ where
#@$ is some hex value. As a result, I cannot get to use the URLESCSEQ
or did I get this wrong?



How do I set this in the HTML HREF statement?

The percent sign is a special character on a URL so you need to "encode".
Every percent needs to be replaced with %25.



Since you're replacing an actual percent sign it makes it a little
confusing. The % in %25 has nothing to do with your data. On a URL, %
is a way to indicate to the browser/server that next 2 positions of
the contain the hex code of a character. The hex code for the percent sign is 25.



So if your data was "my%percent" and it was passed on a URL, it would
need to be encoded "my%25percent".



If your text was "my percent", it would need to be encoded
"my%20percent", as 20 is the character code of space.



So you will use % when encoding special characters for a URL, which is
why your URL doesn't work.



If you are using CGIDEV2 and have a version released this year, it has
a new procedure called UrlEscSeq to make encoding URL parameters easy.


D inpString s 32767 varying
D outString s 32767 varying
*
C eval outString=UrlEscSeq(inpString)

I have a situation in a web program where the percent sign is in
fields in a table. The fields display normally when rendered to the
browser, but when I try to use the field to go to an update page as a
passed parameter, the system/RPG gets confused with the % sign and
does not recognize it as a valid character in the parameter.



I cannot remember how to encapsulate or wrap these field values so
that I can read them normally in the RPG program.



How do we get around this type of error?
