hello every body i have a simple question .

i have this form :

\<%= form\_tag :action=\>‘password’ %\>

Password:\<%= password\_field 😛 , :pass1 , :size=\>‘20’%\>  
Again:\<%= password\_field 😛 , :pass2 , :size=\>‘20’%\>

how can i access the contents of the two field in ruby ?

by doing this : ch1=params[:p][:pass1] i have an error

You have a nil object when you didn’t expect it!  
You might have expected an instance of ActiveRecord::Base.  
The error occurred while evaluating nil.[]

thanks 🙂

give this a try:

\<%= form\_tag( :action =\> ‘search’ ) do %\>  
Password:\<%= password\_field\_tag :pass1, nil , :size=\>‘20’%\>  
  
Password:\<%= password\_field\_tag :pass2, nil , :size=\>‘20’%\>  
  
\<%= submit\_tag %\>  
\<% end %\>

then you can access the values from you controller, like this:

ch1 = params[:pass1]  
ch2 = params{:pass2]

correction: sorry for the typo, you can access the values from your  
controller like this:

ch1 = params[:pass1]  
ch2 = params[:pass2]

Whenever you have a page that sends confidential information back and  
forth  
you have to encrypt it, because when a user hits submit, the html goes  
back  
to the server in pure text and can be read by anyone along the way to  
the  
server. What is done is that PKI infrastructure is used to ensure no one  
in  
the network can intersect the data an read it.

Google SSL, TLS , PKI, Certificates, CA and encryption.

HINT: pages with ssl show a little lock in the status bar of the browser
