Passing a string to a dtml method
by Bruce Eckel 01 Dec '01

01 Dec '01

I do have a question about the anti-spam solution, though. If I create a dtml-method, call it "email", like this: <FORM METHOD="POST" ACTION="/Util/send"> <INPUT TYPE="HIDDEN" NAME="name" VALUE="bruce"> <INPUT TYPE="HIDDEN" NAME="domain" VALUE="EckelObjects.com"> <INPUT TYPE="HIDDEN" NAME="subject" VALUE="Here is the subject line"> <INPUT TYPE="SUBMIT" VALUE="Send Email to Bruce"> </FORM> is there a way to pass the 'subject' string in during a call to the dtml method, so that I could do something like this inside a dtml document or method: <dtml-var email, subject="Here is the subject line"> (obviously I can't use that syntax) Most current information can be found at: http://www.mindview.net/Etc/notes.html =================== Bruce Eckel http://www.BruceEckel.com Contains free electronic books: "Thinking in Java 2e" & "Thinking in C++ 2e" Please subscribe to my free newsletter -- just send any email to: join-eckel-oo-programming(a)earth.lyris.net My schedule can be found at: http://www.mindview.net/Calendar ===================

Email Anti-spam solution

Here's the solution. Instead of using a mailto tag, put something like this on your web page: <FORM METHOD="POST" ACTION="/Util/send"> <INPUT TYPE="HIDDEN" NAME="name" VALUE="bruce"> <INPUT TYPE="HIDDEN" NAME="domain" VALUE="EckelObjects.com"> <INPUT TYPE="HIDDEN" NAME="subject" VALUE="Here is the subject line"> <INPUT TYPE="SUBMIT" VALUE="Send Email to Bruce"> </FORM> Add this in as the external method 'send' (which in my case is in the /Util directory): '''Send email via anti-spam mechanism''' def send(self): mailto = 'mailto:%s@%s' % (self.REQUEST['name'], self.REQUEST['domain']) if self.REQUEST['subject'] != '': mailto += '?Subject=%s' % self.REQUEST['subject'] return self.REQUEST.RESPONSE.redirect(mailto) Voila! No more spambots collecting your address!

Email anti-spam solution

As a follow up to the previous message, on the page: http://www.turnstep.com/Spambot/cgi.html#nomailto I found this: A far better way is to use a POST method. Spambots cannot follow a POST. If they did, they would have to parse apart every FORM tag and also try to set any INPUT tags as well. We're approaching artificial intelligence at this point, so this method is pretty safe. Some example HTML code for a POST method: <FORM METHOD="POST" ACTION="/cgi-bin/Nomailto.pl"> <INPUT TYPE="HIDDEN" NAME="spambot" VALUE="greg"> <INPUT TYPE="HIDDEN" NAME="beware" VALUE="turnstep.com"> <INPUT TYPE="SUBMIT" VALUE="Send me email!"> </FORM> Note that this will work with non-graphical broswers as well. An even nicer way is to tie the submit button in with a button - such as a graphic with your email on it: <INPUT TYPE="IMAGE" SRC="Images/email1.gif"> Most current information can be found at: http://www.mindview.net/Etc/notes.html =================== Bruce Eckel http://www.BruceEckel.com Contains free electronic books: "Thinking in Java 2e" & "Thinking in C++ 2e" Please subscribe to my free newsletter -- just send any email to: join-eckel-oo-programming(a)earth.lyris.net My schedule can be found at: http://www.mindview.net/Calendar ===================

Zope Anti-spam solution

Fooling around, I came up with this external method, which seems to work perfectly: def rewrite(self): return self.REQUEST.RESPONSE.redirect('mailto:Bob@Whoopee.com?Subject=A test of unspam') It seems to do the right thing: pop up email on my machine. And you just put a URL on your page, no javascript needed. I mean, is this cool or what? The question is, would a spider -- which is visiting every url -- know what to do with what comes back from this particular URL? Hmm. I wonder if I can pass the subject string in to the external method somehow.

AUTHENTICATED_USER reverts back to Anonymous User
by Etienne Labuschagne 01 Dec '01

01 Dec '01

Hi there, This is what happens 1) User enters site (REQUEST.AUTHENTICATED_USER == "Anonymous User") 2) User logs in when accesing a "secure" page. (REQUEST.AUTHENTICATED_USER == "myUser") 3) User goes to page that is available for Anonymous Users but which is rendered differently for logged in users. Page must now render as if user is logged in, but does not because REQUEST.AUTHENTICATED_USER == "Anonymous User" again?? After doing some reading it seems as if this is a problem with the way HTML authentication works (Zope does not receive a browser authentication challenge or something like that). Is there a way around this other than using cookies or url mangling? Thanks Etienne
