wpml_current_language

Filters the current language code being displayed, allowing modification before it's used.

add_filter( 'wpml_current_language', $callback, 10, 1 );

Description

This filter allows you to dynamically change the current language code in WordPress. It's useful for scenarios where you need to programmatically influence language-specific functionality, such as content retrieval or display, overriding the default language detection. Use it before language-dependent operations.

Usage

add_filter( 'wpml_current_language', 'your_function_name', 10, 1 );

Return Value

The filtered value.

Examples

/**
 * Example of how to use the 'wpml_current_language' filter to dynamically set the current language.
 * This is useful if you need to temporarily override the globally set language for a specific operation,
 * for instance, when programmatically creating or updating content in a different language.
 *
 * @param string $current_language The current language code, defaults to 'en'.
 * @return string The language code to be used for the current operation.
