Passing Array Via CGI.pm

[shade]

Hello all,

I'm a Perl newbie here and have a quick question regarding CGI.pm.

I have a CGI script that passes an array to another CGI script as
follows:

# sender.cgi
.... (snipped code)
my @fruit = ('apple','orange','pear');
print $q->startform( -action=>'receiver.cgi' ),
$q->submit( -name=>'Export Data' ),
$q->hidden( -name=>'xlfruit' value='@fruit' ),
$q->endform;
.... (snipped code)

# receiver.cgi
.... (snipped code)
my @fruit = param( 'xlfruit' );
print @fruit\n;
print @fruit[0]\n;
.... (snipped code)

The values of the fruit array pass through okay to the new CGI script
but come as a single list. I.e. the out of print @fruit[0] is the
whole line (apple orange pear) rather than just apple. It doesn't
look like the variable is still an array after the pass. Is this
normal or am I missing something?

Thanks for any help.
Tom

the value should be '@fruit'? i'm sure you don't want that.
i guess you want several hidden fields with the name 'xlfruit'.
(you also forgot the comma and wrote = instead of => )
try:
map { $q->hidden( -name => 'xlfruit', value => $_ )} @fruit,

then this:

> my @fruit = param( 'xlfruit' );

will work.

hth, tina

^^^^ ^^

Do not re-type Perl code

Use copy/paste or your editor's "import" function rather than
attempting to type in your code. If you make a typo you will get
followups about your typos instead of about the question you are
trying to get answered.


Like this one.

You are missing comma (,) and greater than (>) characters.

You have missed other problems which are clearly evident.

"... (snipped code)"

This is repeated four times in the originating article.


Printed in part after corrections:

<input type="hidden" name="xlfruit" value="@fruit" />


This is not a problem of typographical errors as you and
your alter ego, Tina, would have a reader believe.

This is a problem of an ignorant troll trying to pass
off a bunch of baloney based on a presumption readers
are too stupid to take notice.

It is clear to me you are also trying to pass off a
bunch of baloney based on a presumption readers are
too stupid to take notice, just as "Tina" has tried.

No I didn't.

I stopped reading the article as soon as I saw that the
code presented could not be the real code. [1]

If the OP can't be troubled to post the actual code they want
to discuss, then I'll let somebody else help them, and move
on to helping one of the more conscientious posters.




[1] many people will do that silently, which is why the Posting

By your own admission you read the problems you missed,
and by your own admission you read four clear indicators
there are no typographical errors, as you claim.

You have forgotten you have me killfiled.

I don't care much for baloney.
