Re: [fw-general] How are you using Zend_Filter_Input?
What I've been doing is creating a subclass of Zend_Filter_Input that
adds the ability to automatically add filters and inputs from class
members and automatically sets up paths for filters/validators. So
the following is possible:
class Input_Form extends Jb_Filter_Input
{
$_filters = array ( ... );
$_validators = array ( ... )';
}
This simplifies code a lot, and is especially useful if you have a
lot of forms requiring validation.
If you're expecting one of your incoming variables to be an array
(say for instance the 'phone[]' variable you described) then
Zend_Filter_Input will automatically apply Filters and Validators to
each element of that array separately (i.e. it wont actually pass an
array to your filters and validators). So in your case you need to
name each of the fields separately and use the fields Meta-command to
specify which fields should be passed to your validator. That way,
your validator will recieve an array containing the fields you
specified. e.g.:
class Input_Form extends Jb_Filter_Input
{
$_filters = array ( ... );
$_validators = array (
'phone' => array (
'fields' => array ('phone-1', 'phone-2', 'phone-3',
'phone-4'),
'PhoneValidator'
)
);
}
Obviously you'd need to implement the phone validator first. SpotSec
had a great example article regarding validating multiple fields with
a single rule:

Re: [fw-general] [fw-core] Utility functions: Calculating binary string length
I disagree - the point in grouping functions by static classes instead of
plain old functions would be to avoid the annoying outcome of php functions
in the past: no standard naming implementation.
Example: what's clearer and more predictable:
strlen()
String::length()
str_split();
String::split()
Other examples of poor function naming conventions which would not be
repeated in static classes of method types:
html_ entity_ decode()
htmlentities()
See what I mean?

I agree that a plain old function would be the best solution in this
situation. I think classes full of static methods provide no real value,
from an object-oriented design perspective. All you get is a bunch of
extra typing.
It's true the framework currently has no place for normal function
libraries, but, personally, I think it would be better to make one than
to start introducing such static classes. The core contributors to this
framework are really smart people; they should be more than capable of
keeping these kinds of function libraries from getting out of control.

Yes - as static class methods ;)
This of course depends on real need - I currently only have one itch to
scratch - but there might be more similar itches, that might be grouped
into related classes - for example:
class Zend_Utility_String
{
/**
* Calculate the byte-length of a string
*
* @param string $string
* @return integer String length
*/
static public function ByteLength($string);
/**
* Split a string into words, grouping quoted phrases together
*
* @param string $string
* @param string $groupBy
* @return array Tokenized words
*/
static public function tokenize($string, $groupBy = '"');
static public function ...
}
class Zend_Utility_Math
{
static public function ...
}
// .. and so on -
// I'd even rename classes like Zend_Debug to Zend_Utility_Debug...
?>
Of course, this approach depends on actual need - since I don't have
good examples, I can't say there really is a need.

[fw-general] Re: [fw-core] Utility functions: Calculating binary string length
This may go against the intended design of the framework in the first place, but in a typical application such a function would just be a standard function, not part of any class. There's no doubt that there are plenty of gaps in the functions that come with PHP, so a problem like this may well crop up again. Couldn't the framework introduce a standard way of defining these utility functions, which could easily be included by Zend_Loader? I've run into the same problem myself when developing a set of my own components that work with/extend ZF.

[fw-general] CGI server, htaccess problem. cannot do rewrite rule to use ZF
Hi, using php 5.2.1 running as php5 I have following .htaccess file AddType application/x-httpd-php5 .php RewriteEngine on RewriteRule !\.(js|ico|gif|jpg|png|css)$ index.php problem is when I try to run example.com I get The requested URL /example.com/www/root/index.php was not found on this server. And I see it is there..Was thinking this is perhaps of CGI or what..as I have never had this problem before. If I change index.php to something else... error messages changes so I guess rewrite engine is actually working. Any idea someone?
[fw-general] Re: [fw-core] Utility functions: Calculating binary string length
Hi,
Well, that's one solution, but IMHO it seems a bit artificial - I mean,
we're not really filtering anything, as in taking input and manipulating
it.

Hi Shahar,
This operation may fit nicely as:
class Zend_Filter_StringByteLength implements Zend_Filter_Interface
{
/**

[fw-general] Utility functions: Calculating binary string length
Hi all, I am working on one of the Http_Client bugs, ZF-2098, which describes a problem the Http_Client has when sending multi-byte encoded (eg. UTF8 Chinese) text in the request body when mbstring is loaded and overloads the strlen() function. This happens because I've been using strlen() to calculate the body size (in bytes - not in characters). This works in most cases, but when mbstring overloads strlen with mb_strlen - what you get is the string length in characters and not in bytes. Brian DeShong already proposed a patch fixing the problem, but I've found that there are several Zend_Http classes that suffer from the same problem. I'm sure that other ZF classes, as well as users, who need a transparent way to calculate string length in bytes, irregardless of loaded extensions or PHP version (no idea what PHP 6 / 5.3 would cause in this case).

[fw-general] Zend_Session_Namespace - Optional argument to create namespace in deeper nodes
Currently, the namespace component creates namespaces only at the root of the session: $user = new Zend_Session_Namespace( 'user' ); => $_SESSION['user'] = array() What if I want to store data deeper in the auth node to just group it and reduce clutter (aka modules) and to be able to count the number of items/namespaces in a node: $_SESSION['auth']['user']['id'] = 1; ([node][namespace][key] = value) In the above case, it would be much more powerful to be able to create the namespace under the 'auth' node so we could configure the keys in the 'user' namespace. We could introduce an optional 'node' argument to the Zend_Session_Namespace::__construct(), like so: $user = new Zend_Session_Namespace( 'user', 'auth' ); [create the user namespace under auth node - auth node created automatically if it does not exist in session] We can even go as deeper as we could by specifying an intelligent node-path: $user = new Zend_Session_Namespace( 'user', 'auth:node2:node3' ); (create the user namespace under $_SESSION[auth][node2][node3] - all created automatically if they do not exist in session) I guess the above feature adds more muscle to the namespace component and enables us to use it more powerfully. http://framework.zend.com/issues/browse/ZF-2103 Thoughts...?
