Validate classes provide a setTranslator() method with
which you can specify a instance of Zend_Translate which
will translate the messages in case of a validation failure. The
getTranslator() method returns the set translator instance.
<?php
$validator = new Zend_Validate_StringLength(array('min' => 8, 'max' => 12));
$translate = new Zend_Translate(
array(
'adapter' => 'array',
'content' => array(
Zend_Validate_StringLength::TOO_SHORT => 'Translated \'%value%\''
),
'locale' => 'en'
)
);
$validator->setTranslator($translate);
With the static setDefaultTranslator() method you can set
a instance of Zend_Translate which will be used for all
validation classes, and can be retrieved with
getDefaultTranslator(). This prevents you from setting a
translator manually for all validator classes, and simplifies your code.
<?php
$translate = new Zend_Translate(
array(
'adapter' => 'array',
'content' => array(
Zend_Validate_StringLength::TOO_SHORT => 'Translated \'%value%\''
),
'locale' => 'en'
)
);
Zend_Validate::setDefaultTranslator($translate);
Note
When you have set an application wide locale within your registry, then this locale will be used as default translator.
Sometimes it is necessary to disable the translator within a validator.
To archive this you can use the setDisableTranslator() method,
which accepts a boolean parameter, and translatorIsDisabled()
to get the set value.
<?php
$validator = new Zend_Validate_StringLength(array('min' => 8, 'max' => 12));
if (!$validator->isTranslatorDisabled()) {
$validator->setDisableTranslator();
}
It is also possible to use a translator instead of setting own messages with
setMessage(). But doing so, you should keep in mind, that the
translator works also on messages you set your own.
