Today I wanted to be able to pass a custom field variable to the WordPress localization (l10n) functions. The custom field is a select field, so all the possible outputs are known.<\/p>\n

WordPress uses PO and MO files for translations. These are generated by scanning the site for __()<\/code> and _e()<\/code> functions, with a programme such as Poedit, to generate the list of translatable strings.<\/p>\n

Using variables in these functions, like _e($output, 'text-domain')<\/code>, causes a problem. When the scan is done, there is no string to add to the PO file.<\/p>\n

In my case, because the outputs are known, I created a file called manual-translations.php<\/code>, included it from my functions.php<\/code> file and added the translatable strings like:<\/p>\n

[code]__( ‘String one’, ‘text-domain’ );
\n__( ‘Second string’, ‘text-domain’ );
\n__( ‘Stringy cheese’, ‘text-domain’ );[\/code]<\/p>\n

Now when the site is scanned it picks these up and I can now add the translations in Poedit.<\/p>\n

Hope that helps someone out there!<\/p>\n","protected":false},"excerpt":{"rendered":"
