Normally text will be translated without any computation. But sometimes it is necessary
to know if a text is translated or not, therefor the
isTranslated() method can be used.
isTranslated($messageId, $original = false, $locale = null)
takes the text you want to check as its first parameter, and as optional third parameter
the locale for which you want to do the check. The optional second parameter declares
whether translation is fixed to the declared language or a lower set of translations
can be used. If you have a text which can be returned for 'en' but not for 'en_US' you
will normally get the translation returned, but by setting $original
to TRUE, isTranslated() will return
FALSE.
Example 956. Checking if a text is translatable
<?php
$english = array(
'message1' => 'Nachricht 1',
'message2' => 'Nachricht 2',
'message3' => 'Nachricht 3');
$translate = new Zend_Translate(
array(
'adapter' => 'array',
'content' => $english,
'locale' => 'de_AT'
)
);
if ($translate->isTranslated('message1')) {
print "'message1' can be translated";
}
if (!($translate->isTranslated('message1', true, 'de'))) {
print "'message1' can not be translated to 'de'"
. " as it's available only in 'de_AT'";
}
if ($translate->isTranslated('message1', false, 'de')) {
print "'message1' can be translated in 'de_AT' as it falls back to 'de'";
}
