If you want to disable comments in WordPress based on the user’s language, you can do so by using the following steps:
Step 1. Install and activate the “GeoIP Detection” plugin. This plugin allows you to detect the user’s language based on their IP address.
Step 2. Add the following code to your theme’s functions.php file:
function df_disable_comments_based_on_language($open, $post_id) {
// Replace XX with the two-letter language code for the language where you want to disable comments
if (geoip_detect2_get_info_from_current_ip()->language->isoCode == 'XX') {
return false;
}
return $open;
}
add_filter('comments_open', 'df_disable_comments_based_on_language', 20, 2);
This code will disable comments for users using the language with the specified ISO code. You can add multiple languages by separating the ISO codes with a pipe (|) symbol, like this:
if (geoip_detect2_get_info_from_current_ip()->language->isoCode == 'XX|YY|ZZ') {
return false;
}
Keep in mind that this method may not be completely reliable, as it relies on the accuracy of IP address geolocation data. Additionally, some users may use a language other than their native language, so this method may not always accurately detect the user’s language.
