Is it possible to override single plugin translation in function.php file and how that can be done?

  • Would you add the example code containing the string that you're trying to translate? This does sound doable. – Dave Romsey Mar 3 '18 at 20:42
  • Haven't any code, just asking if it is possible. – Roger Wayne Mar 3 '18 at 21:22
  • Okay, I've posted an example of a typical scenario. – Dave Romsey Mar 3 '18 at 21:25

Here's an example where a string from a certain text domain is translated using the gettext filter:

 * Translate a certain string from a particular text domain.
 * @param string $translation  Translated text.
 * @param string $text         Text to translate.
 * @param string $domain       Text domain. Unique identifier for retrieving translated strings.
 * @return string
add_filter( 'gettext', 'wpse_translate_string', 10, 3 );
function wpse_translate_string( $translation, $text, $domain ) {
    if ( 'plugin_text_domain' === $domain ) {
        if ( 'Original string...' === $text ) {
            $translation = 'New string!';

    return $translation;

You can even override single messages if you go directly to your source code.

function foo(){
    // old message is commented, so you can go back anytime.
    //echo wp_send_json(array('status' => 'error', 'error_message' => esc_html__('Error Message', 'osetin')));
    // message is overriden 
    echo wp_send_json(array('status' => 'error', 'error_message' => esc_html__('Overriden message with any text you want', 'osetin')));
