Re: [Zope] Newbie question: FORM processing in Zope.
A great resource for newbies is the collection of How-To's http://www.zope.org/Documentation/How-To (or better yet: http://www.zope.org/Members/AlexR/tips/howto_list where you can use browser search to find what you need). Search for "forms" and you will see, for example: http://www.zope.org/Members/jules/smarterforms_html In short, the methods of Zope objects are all "CGI scripts". For the "action" of a form, you supply the url of a form-handling method of some Zope object you have created. When that method runs, form fields are stored in the dictionary (hash, to you) that implements the namespace for the request. You access them as simple DTML variables: e.g. If you want to send the value of that form field on to another form, you do it much the same as in Perl -- you code a hidden form field and assign it the value . -- Hope that helps -- Loren - Original Message - From: "Amit Redij" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: August 28, 2000 04:45 AM Subject: [Zope] Newbie question: FORM processing in Zope. > > hi, > > I am a Perl/CGI programmer, trying out Zope. > I am confused right now about > HOW TO process FORM variables? > and most important thing is > how to validate form inputs.(like same thing is best done in PERL using > regex) > > that is, if I have a html having some form variables and a submit > button.

Re: [Zope] Newbie question: FORM processing in Zope.
Easy and hard answer. The easy answer is forget what you know about scripts/cgi and pulling in form variables from some sort of CGI method (perl module). Since Zope is a constant running process it does not require that you point to a script. Hard Answer: The basics are that all you have to do is give the form element a name (as you would in any form) and point the action of the form to another DTML Method/Document. In that M/D all you have to do to get the variable is call it with 1) Create a form page with 'submit' with one text input box with a name of 'email_address'. 2) Point the action to a method called 'result' and create that 3) In the 'result' method include this code 4) Play around. When you submit from one you should be taken to the second page and the email_address should be there. Now, for validation you can do all sorts of tricky things. I happen to like to have the form point back to itself and have one method handle the entire activity. You can validate things by asking for them, or trying to do something else like put them into a database/email. If they are not there you will get an error so you can use . What makes Zope great is that I can have the form and function in the same page (easier to update/check). Examples: (these are live and in production so please be kind) http://fundraising.gotschool.com/tell_a_friend.html http://market.gotschool.com/ (click on register for either school or supplier and notice how the form is different for both). Same thing done twice.

[Zope] Newbie question: FORM processing in Zope.
hi, I am a Perl/CGI programmer, trying out Zope. I am confused right now about HOW TO process FORM variables? and most important thing is how to validate form inputs.(like same thing is best done in PERL using regex) that is, if I have a html having some form variables and a submit button. I click on the submit button. it should call some script..right? My question is how to pass values from one script to another. how is this done in Zope? thanks a lot in advance. regards Amit .--. |o_o | |\_/ | // \ \Amit Redij (| | ) mailto:[EMAIL PROTECTED] /'\_ _/`\ \___)=(___/ ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
