This :

foreach($time_attendance as $attn_key => $attn_value){
    $SQL = "INSERT INTO tbl_time(employee_id,time_date,time_attendance) 
        VALUES('$attn_key','$cur_date','A')";
    $atten_date = mysqli_query($this->link, $SQL);

    if ($atten_date) {
        $massage = "<div class=''><h5>Attendance insert successfully</h5></div>";
        return $massage;
    }
}

Literally ask to break the foreach with return $massage; if you query succeed... So yes, you'll only have one record.

Put your return outside the foreach.
