get_phrase_info

$info = $language->get_phrase_info( $phraseid )

Returns a hash describing the phrase $phraseid. Contains:

langid - the language the phrase is from
phraseid - the phrase ID
xml - the raw XML fragment
fallback - whether the phrase was from the fallback language
system - whether the phrase was from the system files
filename - the file the phrase came from
 

If $phraseid doesn't exist returns undef.

User Comments


get_phrase_ids

$phraseids = $language->get_phrase_ids( $fallback )

Returns a reference to an array of all phrase ids that are defined in this language (repository and system).

If $fallback is true returns any additional phrase IDs defined in the fallback language.

User Comments


phrase

$xhtml = $language->phrase( $phraseid, $inserts )

Return an XHTML DOM structure for the phrase with the given phraseid.

The $phraseid is looked for in the following order, if it's not in one phrase file the system checks the next.

1. This languages repository specific phrases.

2. The fallback languages repository specific phrases (if there is a fallback).

3. This languages general phrases.

4. The fallback languages general phrases (if there is a fallback).

5. Failing that it returns an XHTML DOM encoded error.

If the phrase contains pin elements then $inserts must be a reference to a hash. Each pin has a name attribute. For each pin there must be a key in $inserts of the name. The value is a XHTML DOM object which will replace the pin when returing this phrase.

User Comments


has_phrase

$boolean = $language->has_phrase( $phraseid )

Returns true if the $phraseid is defined for this language. Returns false if it is only available as a fallback or unavailable.
