Pass parameters to an #exec cgi instruction

[chapo]

Hi Everyone,

I am trying to pass parameters to a perl script using

<!--#exec cgi="/cgi-bin/mywebsite/myscript.pl?param1=value1&param2=value2" -->

but it doesn't seem to work.

Can I do something like

<!--#include virtual="/cgi-bin/mywebsite/myscript.pl value1 value2" -->

instead ?

If not, what is the recommended way ?

Thank yo for your help.

welcome to WebmasterWorld, chapo!


http://httpd.apache.org/docs/2.0/mod/mod_include.html#element.exec

The include virtual element should be used in preference to exec cgi. In particular, if you need to pass additional arguments to a CGI program, using the query string, this cannot be done with exec cgi, but can be done with include virtual, as shown here:

<!--#include virtual="/cgi-bin/example.cgi?argument=value" -->

Thank you for your answer.

What I need to do is have a mix of "local" variables (that I would pass as arguments of the

#include virtual

) and "global" variables in the URL of the webpage.

So I need to use CGI within my

#include virtual

for "global" as well as "local" variables but it doesn't seem to work. It allows me to get the "local" variables with

cgi->param("myvariablename")

but it won't detect the "global" ones.

Any pointers ?

Cheers

You can set variables using SSI. These would be available to the script if they are set before the script is called:

<!--#set var="widget" value="red" -->

You can also pass environmental variables to the script by prepending a $ character to the env name:

<!--#include virtual=/cgi-bin/example.cgi?ip=$REMOTE_ADDR" -->

Hope this helps.

Sorry I am a bit of a newbie here but what is the difference between a regular variable on my webpage and an environmental variable ?

Let's say my URL looks like www.blabla.com/index.shtml?dt=20130625
And I want to use dt (20130625) as one of the parameters to my Perl script. Is that doable using your syntax of #include virtual ?

You're passing a query string parameter to your perl script. This is stored in environmental variable QUERY_STRING. What you need to do is parse $ENV{'QUERY_STRING'} for dt=value

I am not though.

My URL is as above (www.blabla.com/index.shtml?dt=20130625) but the call to my script is done through an include virtual

<!--#include virtual="/cgi-bin/mywebsite/myscript.pl?param1=value1&param2=value2" -->
and the QUERY_STRING variable only contains what I have called the "local" variables (param1 and param2).

dt=20130625 is not part of the QUERY_STRING.

What I would like to do is have
<!--#include virtual="/cgi-bin/mywebsite/myscript.pl?param1=value1&param2=value2&dt=20130625" -->

where the dt=20130625 is dependant on what is in the URL (I can also store the 20130625 value in a variable)

Have I misunderstood something ?

[Key_Master]

Maybe I am misunderstanding something. Where is dt=20130625 coming from? If it's a query string parameter in the url of the page that is using SSI you can try:

<!--#include virtual="/cgi-bin/mywebsite/myscript.pl?param1=value1&param2=value2&$QUERY_STRING" -->

Great that did the trick !
Thank you very much for your help.
