[fw-general] POSTDATA problem

[nickt66]

I have this scenario

Page A
- Gathers data from user in form.
- It POSTS data to Page B

Page B
- Writes POST data to db
- Displays POST data

The problem is if the user goes from Page A -> Page B -> Page C (back
button) -> Page B then when they go back to Page B the POST data gets
written to the db again. Aside from the inefficiency, this is a problem
because stats are being incremented each time. So the data is being made
invalid by the user backing through Page B.

I tried solving it like this:

Page A
- Gathers data from user in form.
- It POSTS data to Page Z

Page Z
- Writes POST data to db
- Redirects to Page B

Page B
- Displays the POST data

This works great in the sense that going from C back to B back to A doesn't
break the db data because Page Z is never hit again. 

But here's the problem - I need to POST the data from Page Z to Page B so
that it can display the data. The data in question is an array of JSON data. 

I tried using Zend_Http_Client and POST but that doesn't cause a redirect
from Z to B. Instead I get an error with the framework complaining it can't
find a view for Page Z (because of course, there isn't supposed to be one).

So, if I'm in a controller action handler, how do I redirect to another
action handler and POST data to that handler?

Thanks

Nick

[fw-general] Zend_Filter_Input problem in Zend Framework 1.9

[nickt66]

I've run into a problem with Zend_FIlter_Input and the ZF1.9 release. I have
various controller actions that start by doing something like this:

$input =  new Zend_Filter_Input(array('lesson' => 'digits'), array('lesson'
=> 'int'), $this->getRequest()->getUserParams()); 

and then go on to use retrieved params like this: $input->lesson 

This code has worked fine on various versions of the Framework up until 1.9.
Now, on 1.9 running on Production (PHP 5.2.1) $input->lesson is NULL. 

If I dump out $input, the debug output is identical under 1.8 and 1.9. (see
below for output). And in either case I can see the correct value for
lesson. But when I retrieve it, as above, I get NULL.

Even more curiously, the code continues to work fine with 1.9 on my
development machine (OS X 10.4.11, PHP 5.2.4).

Obviously it is a show stopper for me as none of my controller actions can
retrieve URL params any more! I'm a newbie, so this kind of system specific
problem has me scratching my head.
