If you want to add a question to Tutor LMS system from your custom plugin or functionality, then you can use the tutor_add_question_data filter. Here is a sample snippet to help you understand the available parameters-
apply_filters('tutor_add_question_data', array(
'comment_post_ID' => $course_id,
'comment_author' => $user->user_login,
'comment_date' => $date,
'comment_date_gmt' => get_gmt_from_date($date),
'comment_content' => $question,
'comment_approved' => 'waiting_for_answer',
'comment_agent' => 'TutorLMSPlugin',
'comment_type' => 'tutor_q_and_a',
'user_id' => $user_id,
));Similarly, the filter tutor_add_answer_data filter lets you add an answer to the Q&A system of Tutor LMS.
apply_filters('tutor_add_answer_data', array(
'comment_post_ID' => $question->comment_post_ID,
'comment_author' => $user->user_login,
'comment_date' => $date,
'comment_date_gmt' => get_gmt_from_date($date),
'comment_content' => $answer,
'comment_approved' => 'approved',
'comment_agent' => 'TutorLMSPlugin',
'comment_type' => 'tutor_q_and_a',
'comment_parent' => $question_id,
'user_id' => $user_id,
));If you want to customize the validation messages on the login screen, you can use the tutor_process_login_errors filter like below-
apply_filters( 'tutor_process_login_errors', $validation_error, $creds['user_login'], $creds['user_password'] );apply_filters( 'tutor_login_credentials', $creds ), is_ssl() );apply_filters('tutor_login_redirect_url', $redirect_to)apply_filters( 'login_errors', $e->getMessage()) );Assets.php
