I am trying to write a cgi program which takes some parameters. I have the following test cgi file:

Code:

#!/bin/sh

start_html()

{

        echo "Content-Type: text/html"

        echo ""

        cat <<EOF

<html>

<head>

<title>

Title

</title>

</head>

<body>

EOF

}

# Send the closing HTML

end_html()

{

  cat <<EOF

</body>

</html>

EOF

}

start_html

cat <<EOF

parm1=$1

parm2=$2

input1=$INPUTPARM1

input2=$INPUTPARM2

EOF

end_html

exit 0

If I call it like this, $1 comes through as expected (I use the Play button to activate the link):

Code:

<a href="http://localhost.drives:8883/HARD_DISK/test.cgi?test" TVID="PLAY"/>

parm1=test

parm2=

input1=

input2=

However, if I try to set up a variable like this, it does not work as expected:

Code:

<a href="http://localhost.drives:8883/HARD_DISK/test.cgi?INPUTPARM1=test" TVID="PLAY"/>

parm1=INPUTPARM1=test

parm2=

input1=

input2=

Multiple input variables are also not working as expected:

Code:

<a href="http://localhost.drives:8883/HARD_DISK/test.cgi?INPUTPARM1=test&INPUTPARM2=test" TVID="PLAY"/>

parm1=INPUTPARM1=test1%26INPUTPARM2=test

parm2=

input1=

input2=

Am I doing something wrong? Is what I am trying to do even possible?

You are doing nothing wrong, just all the HTTP GET parameters are stored in $1.
You need to manually split them to correct variables.

Ah right, of course.

Thanks for the quick reply. I saw examples somewhere of being able to pass in key/value pairs to a CGI, but I guess those programs were manually splitting the parms as you suggest.
