Zend_Locale and 1.8 problems

[bmatzner]

Hello,

before I post these as issues on the Issue Tracker, I wanted to quickly address a few problems I've encountered after upgrading to 1.8.0. The application in question used to work perfectly fine using 1.7.x.

First error I encountered was a "cache_dir is not writable" exception. After some time trying to check why the cache_dir I was setting for my own application would break all of a sudden, I found that Zend_Locale is the culprit, obviously it's using a cache of its own, and the default folder wasn't writable, so I had to set the cache_dir like so:

Zend_Locale_Format::setOptions(array('cache' => $myWritableCacheDir));

With that out of the way, the next obstacle was an empty $locale string passed to the Int and Float validators ("Locale '' not found"). The docs say that these methods are using the application-wide locale, which I'm setting in the bootstrap:

        setlocale(LC_ALL, 'de_DE');
        $locale = new Zend_Locale('de_DE');
        Zend_Registry::set('Zend_Locale', $locale);
        Zend_Locale::setDefault('de_DE');
        Zend_Locale_Format::setOptions(
            array('cache' => $myWritableCacheDir, 'locale' => $locale));

When adding validators to a Zend_Form_Element using the addValidator() method, it is unclear to me on how to pass in a locale, so for now I worked around it by extending Zend_Validate_Int and specifically setting the locale.

Either behavior seems buggish to me...

Zend_Locale does only then use a cache itself when you don't set any.
When you set a cache as demanded in the manual, then your cache is used.
Using no cache when working with the I18N core is really a no-go.

No, you're wrong.
This message means not that you gave a null as parameter, it means that you
gave a empty string ('') as locale.
The question is not what you set into registry, the question is how you
initiate the validator which you did not show.

Also to note:
You set the locale object to registry, but you change it after you saved it
to the registry.
This means that the changes done afterwards are not within the registry.

addValidator accepts as optional parameter a array of options for this
validator.
But you could also call setLocale on that validator like described in the
manual.

Hello Thomas,

thanks for your response.

So far I didn't set locale at all, which is why I'm wondering it's empty and not null...

I don't see what I'm changing there. Isn't the application-wide locale meant to look into the registry for a Zend_Locale setting? If it's set to be de_DE, that's exactly what is available later on.

I switched things around like this:
        $locale = new Zend_Locale('de_DE');
        Zend_Locale::setDefault('de_DE');
        Zend_Locale_Format::setOptions(
            array('cache' => $cache, 'locale' => $locale));        
        Zend_Registry::set('Zend_Locale', $locale);

but the error still occurs. Are you sure the application-wide locale is taken into account there? When looking at the Zend_Validate_Int code I see it expects a $locale param passed in, default to null. Where does it check for the locale stored in the registry when no locale is passed in by me when adding the validator?

I can only get this to work if I'm specifically setting this parameter (however, for others, such as the GreaterThan validator, it won't work, as th

How would I do that when using Zend_Form_Element::addValidator('int')?

I'll try to set up an isolated test case which I can post in the next couple of days.
