This is how I was able to change the messages, there may be a better way to go about it but to see all messages echo print_r($messages) or maybe if the creator catches this thread he could list all the $messages names:
/** Contact Form 7 Default Messages **/
function wpcf7_custom_messages($messages){
$messages['mail_sent_ok']['default'] = 'Your message has been sent!';
$messages['mail_sent_ng']['default'] = 'Your message could not be sent.';
$messages['validation_error']['default'] = 'Validation errors occurred. Check your information and submit again.';
$messages['spam']['default'] = 'Your message could not be sent.';
$messages['invalid_required']['default'] = 'This field is required.';
$messages['captcha_not_match']['default'] = 'Incorrect CAPTCHA - try again.';
$messages['invalid_email']['default'] = 'Invalid email address.';
return $messages;
}
add_filter( 'wpcf7_messages', 'wpcf7_custom_messages', 999 );
It works. A big thank you for this!
I’ve been messing around trying to do it with a translation file, which worked but is not really the right way to do it 😀 Luckily just searched again and caught this post.
Folks, remember that if you’ve already made a form, the result messages won’t change there, because they have already been saved. Only when you start a new form. (It only took me a couple days to figure out why my messages weren’t changing — hopefully you are smarter than me!)
