How can I get HTML's varibles in embeded ruby?

Zhan feng Wang

E.g.,I have following variables:
myInput, DataFile,TagFile in the following segment HTML codes.

<form name="myInput" action="deTap3-1.rhtml" method="POST">
<pre>
Select Asn1 File: <input name="DataFile" type="file" >
Select Asn1-bas File: <input name="TagFile" type="file">
<input type="hidden" name="action" value="submitted">
<input type="submit" name="Go" value="Go!">
<input type="reset" name="reset" value="Reset" OnClick="init()">
</pre>
</form>



If in PHP, I can easily get them by $p_DataFile, $p_TagFile etc, How can
I get the variables in embeded ruby?

Thanks

<form name="myInput" action="deTap3-1.rhtml" method="POST">
<pre>
Select Asn1 File: <input name="DataFile" type="file" >
Select Asn1-bas File: <input name="TagFile" type="file">
<input type="hidden" name="action" value="submitted">
<input type="submit" name="Go" value="Go!">
<input type="reset" name="reset" value="Reset" OnClick="init()">
</pre>
</form>

just a note, but i don't think you want the 'form' action to go to the
file itself (the rhtml) .. it should go to the corresponding action that
calls that template.

i believe what you are seeking for is params[:DataFile],
params[:TagFile], etc.
(this may be good for the ruby on rails forum, rather than this plain
ruby forum) http://www.ruby-forum.c...

anyway hth.
happy sunday

You probably want to use the CGI class:
http://ruby-doc.org/core/classe...

That page has plenty of tutorials on it, but the basics are:

require 'cgi'
cgi = CGI.new
data_file = cgi['DataFile']

That'll give you the value of the DataFile text field.

Isn't hpricot (http://redhanded.hobix.com/inspect/hpri...) an
html parser package?
