How to use ngettext_with_context filter in WordPress

To get started with the ngettext_with_context filter, you’ll need to register it using add_filter. This can be done in the functions.php file of your activated theme or, even better, by creating a custom WordPress Plugin with the WePlugins approach, ensuring your theme updates don’t break anything.

Here’s a quick look at the parameters you’ll be dealing with:

• $translation: Translated text.
• $single: The text to be used if the number is singular.
• $plural: The text to be used if the number is plural.
• $number: The number to compare against to use either the singular or plural form.
• $context: Context information for the translators.
• $domain: Text domain. Unique identifier for retrieving translated strings.

Example 1: Basic Usage

Here’s a straightforward example of how to use the ngettext_with_context hook.

    function weplugins_modify_ngettext_with_context_defaults($translation, $single, $plural, $number, $context, $domain) { 
        // Update the $translation variable according to your website requirements and return this variable.
        return $translation; 
    }
    // Add the filter
    add_filter( "ngettext_with_context", "weplugins_modify_ngettext_with_context_defaults", 10, 6 );
    

Example 2: Conditional Translation

Sometimes, you might need to apply conditional logic to your translations. Here’s how you can do it:

    function weplugins_conditional_ngettext_with_context($translation, $single, $plural, $number, $context, $domain) {
        if($number > 1) {
            $translation = $plural;
        } else {
            $translation = $single;
        }
        return $translation;
    }
    // Add the filter
    add_filter( "ngettext_with_context", "weplugins_conditional_ngettext_with_context", 10, 6 );
    

Example 3: Removing a Hook

If you ever need to remove a hook callback, here’s how you can do it:

    // Remove the filter
    remove_filter( "ngettext_with_context", "weplugins_modify_ngettext_with_context_defaults", 10, 6 );
    

Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.
