Lots of ways.

You could write your array out to a file and get your next cgi to read
it from the file, or you can pass it along with the URL request using a
hidden form variable eg:

Put something like this inside your <form> tag on your first page:

<input type=3Dhidden name=3Dmyarray value=3D"foo bar bop">

and then your next cgi can then get at it by doing the following:

do ../web-lib.pl
&ReadParse;
my @myarray =3D split(" ", $in{'myarray'});  =20

Which is fine as long as your values don't contain spaces.

Another handy trick is that if you have multiple form variables with the
same name e.g. something like:
<input type=3Dhidden name=3Dmyarray value=3D"foo">
<input type=3Dhidden name=3Dmyarray value=3D"bar">
<input type=3Dhidden name=3Dmyarray value=3D"bop">
in your html then when the form is submitted, $in{'myarray'} will
contain "foo\0bar\0bop"

you can then make an array out of what gets submited by doing

do ../web-lib.pl
&ReadParse;
my @myarray =3D split("\0", $in{'myarray'});

None of this code is tested by the way - should be close enough to find
out what is wrong if it is isn't though.

Hope this helps,

Jon

Hello,

  I have a question,about the miniserv...   =20

  How can I pass an array to another page? for example, I add an array
in some module, and I want to process it in another cgi file, How should
I do?

  In fact, that's a CGI problem,but it's always trouble me, I have to
produce a new array in every CGI...

   How do you deal with it?

Thank you.

Andrew.R.J
