Dear Xibo developers
I got a question want to ask.
I changed some words in the code of PHP files.
If I want to add the words to locale/zh\_TW.mo file, how should I do???
Thanks.

You’d need to re-parse the files into a POT and translate manually… using something like PoEdit. Unless your changes are something that the project should also change, in which case we can raise a bug for it and get it fixed in the next release.

Dear Xibo developers
Thanks your previous response.
My condition is that I create a new word in the php code.
Ex: At display page, I create a “Preview” word next to default layout button. Then I add this new word to default.pot file and output to zh\_TW.mo file. But it doesn’t to be translated.
What step I missed???
Thank you for reading.

Please can you provide a code snippet for what you have changed?

Hi, Dan
Sure.
I use Xibo version 1.2.0.
Here is the code segment I new added in display.class.php, line 547.
Code: &button id=“preview\_btn” class=“XiboFormButton” onclick=“Preview($displayid, ‘$defaultlayout\_url’, this);” &&span&Preview&/span&&/button&
I’m sorry that the code can not be display directly on the webpage, so I change “\<”, “\>” symbol to “&”.
The word “Preview” between “span” tag wasn’t exist in the original default.pot and display.class.php file.
I created it.
If I want this word can be translated to zh\_TW correctly.
How should I do???
Thanks.

Translatable strings have to be enclosed in `__()` so that they are translated at run time - it doesn’t just translate text (otherwise it wouldn’t know what to translate)
