Custom strings for translation using Polylang plugin

Question

I'm using WP 3.5 and Polylang 0.9.8 plugin to make translations to different languages.

All is good, and the plugin works fine, but now I'm facing a problem -- I need to translate custom strings, for example, strings inside widgets.

What can you recommend me to solve this problem?

ADDED: For example (I'm taling about text in widgets, but not header), can I add some string constants or so and write them from php-code into my page -- and got them to translate on String translation page of Polylang?

Answer 1

Use this

pll_register_string()

on functions.php

Use it like this:

pll_register_string

Allows plugins to add their own strings in the “strings translation” panel. The function must be called on admin side (the functions.php file is OK for themes).
Usage:

pll_register_string($name, $string, $multiline);
‘$name’ => (required) name provided for sorting convenience (ex: ‘myplugin’)
‘$string’ => (required) the string to translate
‘$multiline’ => (optional) if set to true, the translation text field will be multiline, defaults to false

So:

pll_register_string('Header Title', 'The title you want to appear');

Then on dashboard config, on languages, you are going to find a tap called "strings". There you're going to have this new created string, and an input text to fill the translation text for every active language on your site. Write translations, and then use the funcions:

pll_e() to directly echo, or pll__() to manually echo it. Your'ge going to use it like:

pll_e('The title you want to appear'); or
echo pll__('The title you want to appear');

That's it! :)
