Question

在php中添加Span

这部分工作正常

<select id="selectbasic" name="country" class="form-control">
<?php
    $mysqli = new mysqli("localhost", "root", "", "gocall");
    if (mysqli_connect_errno()) {
        printf("Échec de la connexion : %s\n", mysqli_connect_error());
        exit();
    }

    if ($result = mysqli_query($mysqli, "SELECT country_name FROM country ")) {
        $row= mysqli_num_rows($result);
        while ($row= mysqli_fetch_array($result)) {
            $id=$row[0];
            echo" <option value=\"FR\">$id</option>";
        }
    }
?>
</select>

将组合框保存在数据库中

这是错误

<?php
    if (isset($_POST['addcustomer'])) {
        $name=$_POST['name'];
        $lastname=$_POST['lastname'];
        $email=$_POST['email'];
        $password=$_POST['password'];
        $country=$_POST['country'];

        $mysqli = new mysqli("localhost", "root", "", "db1");

        if (mysqli_connect_errno()) {
            printf("Échec de la connexion : %s\n", mysqli_connect_error());
            exit();
        }
        $req="INSERT INTO customer 
                VALUES (NULL,'$name','$lastname','$email','$password',$country)";
        $mysqli->query($req);
        $mysqli->close();
    }
?>

   <?php
                            ini_set('display_errors', 1); ini_set('log_errors',1); error_reporting(E_ALL); mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
                            if (isset($_POST['addcustomer']))
                            {
                                $name=$_POST['name'];
                                $lastname=$_POST['lastname'];
                                $email=$_POST['email'];
                                $password=$_POST['password'];
                                $country=$_POST['country'];

                   $mysqli = new mysqli("localhost", "root", "", "db1");

                                if (mysqli_connect_errno()) {
                                    printf("Échec de la connexion : %s\n", mysqli_connect_error());
                                    exit();
                                }
                                $req="INSERT INTO customer VALUES (NULL,'$name','$lastname','$email','$password','$country')";
                                $mysqli->query($req);
                                $mysqli->close();
                            }
                            ?>

Answer 2

你的下拉应该是;

 <select id="selectbasic" name="country" class="form-control">
<?php
    $mysqli = new mysqli("localhost", "root", "", "gocall");
    if (mysqli_connect_errno()) {
        printf("Échec de la connexion : %s\n", mysqli_connect_error());
        exit();
    }

    if ($result = mysqli_query($mysqli, "SELECT country_id,country_name FROM country ")) {
        $row= mysqli_num_rows($result);
        while ($row= mysqli_fetch_array($result)) {
            $id=$row['country_id'];
            $country_name=$row['country_name'];
            echo" <option value='$id'> $country_name </option>";
        }
    }
?>
</select>
