Why is the data not going to the database?

Question

PHP

Why is the "status" select data not being passed to the database?

<div class="row">
                
                
                <form method="POST" action="add_orders.php">
                    <div class="col-md-4">

            <div class="container-form">
                <div class="input_class">
                <input type="title" name ="title" class="input_text input_form" placeholder="Заголовок">
                <input type="name" name ="name" class="input_text input_form" placeholder="Заказчик">
               

                
                </div>
            </div>
            </div>

            <div class="col-md-4">
                <div class="container-form">
                <div class="input_class">
                <input type="hidden" name="date" class="input_text input_form" value="<?php echo date('Y-m-d') ?>">
         
                </div>
                </div>
            </div>

            <div class="col-md-4">
                <div class="container-form">
                <div class="input_class">
               
                <input type="text" name="summ" class="input_text input_form" placeholder="Сумма">

                <select name="status" class="select_option input_form">
                    <option value="0">Статус</option>
                    <option value="1">Завершен</option>
                    <option value="2">Идут работы</option>
                </select>


                </div>
                </div>
            </div>


            <input type="submit" name="add" value="Добавить">

            </form>


            <?php 
            include("config/config_database.php");

            if(isset($_POST['add'])){

            $title = strip_tags(trim($_POST['title']));
            $name = strip_tags(trim($_POST['name']));
            $summ = strip_tags(trim($_POST['summ']));
            $status = $_POST['status'];
           $date = $_POST['date'];
                        

            mysql_query(" INSERT INTO eb_orders(title, name, summ, status, date) 
                VALUES ('$title', '$name', '$summ', '$status' $date') ");

            mysql_close();

            echo "News added";
        }
             ?>
            </div>

Answer 1

This is:
mysql_query(" INSERT INTO eb_orders(title, name, summ, status, date)
VALUES ('$title', '$name', '$summ', '$status' $date')");
Replace with this:
mysql_query(" INSERT INTO eb_orders(title, name, summ, status, date)
VALUES ('$title', '$name', '$summ', '$status', '$date') ") ;

Answer 2

Judging by the code, the request processing should take place in the add_orders.php file, but in fact it takes place in the same file as the form code. Replace form method="POST" action="add_orders.php" with form method="POST" action=""
