Site language –> Available languages empty

Here’s a screenshot

Hello,

please make sure that you return also the array languages that is incoming when you use the hook my_msls_options_get_available_languages to add a language.

Here is an example of your specific use-case:

/**
 * @param array $languages
 * @return string
 */
function my_msls_options_get_available_languages( languages ) {
    if ( ! isset( $languages['en_IN'] ) ) {
        $languages['en_IN'] = 'English (India)';
    }
    return $languages;
}
add_filter( 'msls_options_get_available_languages', 'my_msls_options_get_available_languages' );

As you can see, languages is an associative array. The keys are the language and region code and the value is the description.

Thanks for the quick reply!
Where do I paste this hook?

When I paste this hook in functions.php I get a ‘critical error’ in the backend.

When I create a plugin, I get this warning: “Plugin could not be activated because it triggered a fatal error.”

I just realized that the above is not correct. This one is better:

/**
 * @param array $languages
 * @return array
 */
function my_msls_options_get_available_languages( $languages ) {
	if ( ! isset( $languages['en_IN'] ) ) {
		$languages['en_IN'] = 'English (India)';
	}
	return $languages;
}
add_filter( 'msls_options_get_available_languages', 'my_msls_options_get_available_languages' );

Thanks again.
I wrote this hook in a plugin and was able to activate the plugin without any warnings.
I guess now I should see the option of ‘Englisch (India)’ in the available languages dropdown.
Unfortunately, this option isn’t shown.

I guess that this has to have also a language file in /wp-content/languages/ — at least as far as I remember.

Thanks, wer’re getting closer!
I copied the en_NZ.po and renamed it to en_IN.po and en_IN.mo.
Now finaly I can select the language en_IN in WordPress, but the code of the site still shows the href lang en-GB

Do you refer to the description that you can set in the settings of the plugin?

This is the language dropdown that extended by your hook (would prefer to have the listing ‘English (India)’ instead of ‘en_IN’:

And this is the html code of the website that has the language en_IN assigned.
The href lang is en-GB, but it needs to be en-IN.

Thanks a lot for your superb support!

I have found a solution for my last problem with the wrong HTML lang attribute.
There’s a plugin called ‘CHL-Change HTML Lang‘ that lets you enter the desired HTML lang attribute in WP –> Settings –> General.

Thanks again for the great support!

Glad I could help! Have fun with the Multisite Language Switcher. ??
