Question

在调用index.php时出现HTML页面提交值时，不会显示错误并刷新页面。但是，数据库表中不会显示任何值。也没有显示错误。请提出解决方案。

数据库名称：cardb 表名：汽车

PHP代码

    <?php

include('index.html');
$conn = new mysqli('localhost','root','','cardb');
if ($conn->connect_error) 
    {
    die("Connection failed: " . $conn->connect_error);
    }
 $seat_value=$_POST['seat'];
 $fuel_value=$_POST['fuel'];
 $class_value=$_POST['class'];
 $body_value=$_POST['bodystyle'];
 $sql = "INSERT INTO car (`seat`,fuel,class,bodystyle)
           VALUES ('$seat_value','$fuel_value','$class_value','$body_value')";  
if ($conn->query($sql) === TRUE) 
    {
    echo "New record created successfully";
    $last_id = $conn->insert_id;
    echo "New record created successfully. Last inserted ID is: " . $last_id;
    } 
    else 
    {
    echo "Error: " . $sql . "<br>" . $conn->error;
    }


$conn->close();
?>

Answer 1

除了what I wrote in comments关于你如何访问该文件（这很重要）：

您的<button type="submit" class="btn btn-embossed btn-primary view" form="inputs" value="Submit">Submit</button> 在<{1}}标记之外。

将“置于”中。

补充说明;您的代码对SQL注入是开放的。使用准备好的声明。
