I'v got a problem translating text that is printed dynamically from a mysql
database. I'm printing body part names and the related muscle names by using
nested tal:repeat. In the inner loop I'd like to echo the muscle name and
translate it if there's a translation available. Here's what I got so far:
ul
li tal:repeat=bodyPart bodyParts
tal:block tal:content=bodyPart/name /
ul
li tal:repeat=muscle php:bodyPart.Muscles
tal:block i18n:translate=
span tal:content=muscle/name /
/tal:block
/li
/ul
/li
/ul
.. but all that the inner loop prints is empty li elements. What am I doing
wrong?
Use this instead:
tal:block i18n:translate=muscle/name
i18n:translate= builds translation key at compile time, ignoring tags and
dynamic content.
i18n:translate=expression will use value of the expression as translation key.
I've changed PHPTAL to reject all-whitespace translation keys. Version in SVN
will now prevent this gotcha.
Oh I see. Then I'v got another guestion since I'm creating my own translator similar to this
http://phptal.org/manual/en/split/i18n-translatekey.html and if I use tal:block
i18n:translate=muscle/name all the translations have to exists.
I want my translator to translate if there's a translation available and use
the key text when there isn't. So I added a few lines to translate function.
Does this seem like a good way of doing this?
public function translate($key, $htmlencode=true) {
$value = @$this-_currentDomain[$key];
if (empty($value)) {
return $key;
}
while (preg_match('/\${(.*?)\}/sm', $value, $m)) {
list ($src, $var) = $m;
if (!array_key_exists($var, $this-_context)) {
$err = sprintf('Interpolation error, var %s not set', $var);
throw new Exception($err);
}
$value = str_replace($src, $this-_context[$var], $value);
}
return $value;
}
