Retrieve query_string on my CGI in ksh/html ?
I've this ksh script in my CGI :

Code:
SERV_LINUX=$(cat /xxx/xxx/xxx/xxx/xxx/xxx/foo.txt | awk -F';' '{print $2}' | sort | uniq)
    
    DATE_Linux=$(cat /xxx/xxx/xxx/xxx/xxx/xxx/foo.txt | awk -F';' '{print $3}' | sort | uniq)

    echo "<form action="LINUX_GNU.ksh" method="post">"
    echo "<select name="SERV">"
    echo "$SERV_LINUX" | while read SERV_LINUX; do
    echo " <option value="$SERV_LINUX">$SERV_LINUX</option>"
    done
    echo "</select>"
    
    echo "<select name="DATE_Linux">"
    echo "$DATE_Linux" | while read DATE_Linux; do
    echo " <option value="$DATE_Linux">$DATE_Linux</option>"
    done
    echo "</select>"
    
    echo "<input type="submit" value="Select">"
    echo "</form>"
    
     echo "</div>"

This piece of script create a dropdown menu which allow to choose a server. On my second page, If I put this :

Code:
read a 
echo $a

I'm able to retrieve the query string like this :

Code:
SERV=my_serv&DATE_Linux=2019-10

I want to know if it's possible to do the same things but only with button ? I mean, If I've 4 options in my dropdown menu, I would like to create 4 buttons, like that :

Code:
SERV_LINUX=$(cat /xxx/xxx/xxx/xxx/xxx/xxx/foo.txt | awk -F';' '{print $2}' | sort | uniq)

echo "<form action="test.ksh" method="post">"
echo "$SERV_LINUX" | while read SERV_LINUX; do
echo "<input type="submit" value="$SERV_LINUX">"
done
echo "</select>"
echo "</form>"

One button for each options of the dropdown. When I will click on the button, a new page will open with the result :

Code:
SERV=my_serv

But When I try that, I've no result... Do you think it's possible ? Do u have any idea to do this ?

Thanks ! Smilie

cgi::compile

CGI::Compile(3pm)					User Contributed Perl Documentation					 CGI::Compile(3pm)

NAME

       CGI::Compile - Compile .cgi scripts to a code reference like ModPerl::Registry

SYNOPSIS

	 use CGI::Compile;
	 my $sub = CGI::Compile->compile("/path/to/script.cgi");

DESCRIPTION

       CGI::Compile is an utility to compile CGI scripts into a code reference that can run many times on its own namespace, as long as the script
       is ready to run on a persistent environment.

       NOTE: for best results, load CGI::Compile before any modules used by your CGIs.

RUN ON PSGI

       Combined with CGI::Emulate::PSGI, your CGI script can be turned into a persistent PSGI application like:

	 use CGI::Emulate::PSGI;
	 use CGI::Compile;

	 my $cgi_script = "/path/to/foo.cgi";
	 my $sub = CGI::Compile->compile($cgi_script);
	 my $app = CGI::Emulate::PSGI->handler($sub);

	 # $app is a PSGI application

CAVEATS

       If your CGI script has a subroutine that references the lexical scope variable outside the subroutine, you'll see warnings such as:

	 Variable "$q" is not available at ...
	 Variable "$counter" will not stay shared at ...

       This is due to the way this module compiles the whole script into a big "sub". To solve this, you have to update your code to pass around
       the lexical variables, or replace "my" with "our". See also <http://perl.apache.org/docs/1.0/guide/porting.html#The_First_Mystery> for more
       details.
