The second day of php practice_PHP tutorial

1. I wrote the add method on my message board

[php] function add(){
//After adding, return the number of affected items. If it is greater than 0, it means the addition is successful
If($this->db->data($_POST)->add()>0){
            echo "Added successfully";
// echo "<script>location.reload()</script>";//Prevent repeated submission of the refreshed form
Header("HTTP/1.1 303 See Other");
        Header("Location: "); //Redirect to the root directory
exit;
                                                        }else {
            die($this->db->error());//Add failure output error message
}  
}

function add(){

//After adding, return the number of affected items. If it is greater than 0, it means the addition is successful
If($this->db->data($_POST)->add()>0){
echo "Added successfully";
//echo "<script>location.reload()</script>";//Prevent repeated submission of the refreshed form
Header("HTTP/1.1 303 See Other");
Header("Location: "); //Redirect to the root directory
exit;
 
}else {
Die($this->db->error());//Add failure output error message
}
