Thanks for the suggestion. That - almost - works. One problem though.
- We use PHP arrays for translations (don't ask me why), so using the ${var}
notation gives undefined variable errors. I can hack around that by using
{var} instead and use a modified PHPTAL_TranslationService::translate()
method. Grabbed from DummyTranslator in the test dir ;-)
function translate($key, $escape=true) {
$translations = $this->getTranslations();
if (array_key_exists($key, $translations)) {
$v = $translations[$key];
} else {
$v = $key;
}
if ($escape) $v = htmlspecialchars($v);
while (preg_match('/\{(.*?)\}/sm', $v, $m)) {
list($src, $var) = $m;
if (!isset($this->vars[$var])) return "!*$var* is not defined!";
$v = str_replace($src, $this->vars[$var], $v);
}
return $v;
}
and a PHPTAL_TranslationService::setVar method like this:
public function setVar($key, $value) {
$this->vars[$key] = $value;
}
The entry in the translation array is:
"titleTranslationKey" => "Drop foto her for at uploade det (max. {maxFilesize}
MB)"
My problem is that setVar() is called *after* translate() so the title in the
resulting document ends up as "!*$var* is not defined!".
If I cheat and initialize the variables array:
private $vars = array('maxFilesize'=>'512 MB');
The result is correctly "Drop foto her for at uploade det (max. 512 MB)".
Well, this was a very long-winding way of asking: Is there any way I can set
the variable in the markup before using it?
