checkbox query in CGI

RajNaidu has asked for the wisdom of the Perl Monks concerning the following question:

I have a CGI form in the below tabular format , with checkbox present only in T1 column. 
In this form , if the checkbox is checked, how do I get the checked value ?

T1 | T2 | T3 | T4

It's hard to tell what part you are having trouble with, so I'm just going to take wild guess. Assuming you have a checkbox in each column, like: `<input type="checkbox" name="T1" value="row1"> <input type="checkbox" name="T1" value="row2"> <input type="checkbox" name="T1" value="row3"> ...` [download] in perl, you would get a list of the values for which the checkbox is checked by `@values = CGI::param("T1");` -- A math joke: r = \| \|csc(θ)\|+\|sec(θ)\|-\|\|csc(θ)\|-\|sec(θ)\|\| \| Online Fortune Cookie Search Office Space merchandise	[reply] [d/l] [select]

Hi, Thanks for the reply. I have two CGI forms, basically. The values checked in one form should be made visible in the other form. Is there a way in CGI to achieve this. -Rajini	[reply]

Yes. The simplest way is to have the form action for the first form be a CGI script that generates the second form, doing whatever it needs to do to make the values visible. You probably want to read the CGI doc and look at some examples, then try to write the code. -- A math joke: r = \| \|csc(θ)\|+\|sec(θ)\|-\|\|csc(θ)\|-\|sec(θ)\|\| \| Online Fortune Cookie Search Office Space merchandise	[reply]
