Re^2: Post from jQuery to Perl - can't access parameters

[stuckdev]

Thanks. I've tried putting in your code. I have two issues (thus far). I'm getting the error:

Can't locate JSON.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at hello_world.pl line 8. BEGIN failed--compilation aborted at hello_world.pl line 8.

on the server. (I'm hosting from 2mhost, so I have no idea what this all means) Do they even have JSON?

The other issue, is that my jquery post is directly in my HTML page, not within a function on a PERL page -- so I'm having a hard time extrapolating your code and putting it into straight HTML format because I'm not exactly what you're doing with the whole J. stuff.

Hi stuckdev,

As marto said, you need to have JSON installed. You could ask 2mhost to install it for you, or try to install it locally (if you have that capability). It's not a complete requirement, but JSON ("Javascript Object Notation") is a wonderful means of simplifying how data is serialized for passing between client and server.

As for your HTML page, if it's separate from your CGI, you can just put everything printed out by subroutine "print_html() into the html page, except for the "Content-type:  text/html" (which will be printed for you automatically by the server, since it's in HTML.

You would then change $url in the function ajax_text(), in this line:

    url:   "$url",

to be whatever the name of your actual CGI/Perl script was instead.

However, please note that you will still need the headers printed from your server-side Perl/CGI script; eg.:

    print "Content-type:  application/json\n\n";

If you forget that, you'll get something like this error (from my /var/log/httpd/error_log file):

[Wed Mar 13 11:41:37 2013] [error] [client 192.168.17.33] Premature en
+d of script headers: 1023196.cgi, referer: http://mymachine.com/10231
+96.cgi

Does that help you get further?

This means your host don't have JSON instaled, depending on your hosting deal you may be able to install modules easily, or it could be something they have to do for you. This is not a Core module. Also 5.8.8 is a fairly old verison of Perl. See also here and here.
