Question

我正在尝试将html文件中的数据插入到我的数据库“customers”

中

然而，我可以连接到数据库，但无法将html文件中的数据插入到我的数据库中

error的截图注意：

我没有为phpmyadmin设置密码，只是将用户名设置为“root”
所有文件都存储在同一文件夹（C：\ wamp64 \ www）

customers.html客户

<!DOCTYPE html>
<html>
<head>
        <title>customers</title>
</head>
<body>

  <center><form action="SignUp.php" method="POST">
        <input type="text" name="id" placeholder="customer id"><br>
        <input type="text" name="firstname" placeholder="firstname"><br>
        <input type="text" name="orderno" placeholder="order no"> <br>
        <input type="text" name="city" placeholder="city"><br>
        <input type="text" name="price" placeholder="product price"><br>
        <button type="submit">order</button>
     </form>
</center>
</body>
</html>

SignUp.php

<?php

include 'db.php';

$sql= "INSERT INTO customers (id,firstname,orderno,city,price)
VALUES ('345','username','979','city','4465')";

 if($result=mysql_query($sql)==true)
        echo "data inserted successfully";
 else
        echo "failed to insert data";
?>

db.php中

<?php

$conn=mysqli_connect("localhost","root","","customers");
if(!$conn){
        die("connection failed : " .mysqli_connect_error());
}
else{
        echo "connection created successfully"."<br>";
}

?>

我不知道这是否是你的问题但是，customers.html你应该让它customers.php，让你的生活更轻松，而且

本声明

<?php

include 'db.php';

$sql= "INSERT INTO customers (id,firstname,orderno,city,price)
VALUES ('345','username','979','city','4465')";

 if($result=mysql_query($sql)==true)
        echo "data inserted successfully";
 else
        echo "failed to insert data";
?>

应该是

<?php

include 'db.php';

$sql= "INSERT INTO customers (id, firstname, orderno, city, price)
VALUES ('345','username','979','city','4465')";

 if($result=mysql_query($sql)==true) {
        echo "data inserted successfully";
 } else {
        echo "failed to insert data";
 }
?>

您的if/else代码中没有括号。

如果您要使用mysqli连接数据库，您可以将SignUp.php转换为

<?php
$sql = "INSERT INTO MyGuests (id, firstname, orderno, city, price)
VALUES ('345', 'username', '979', 'city', '4465')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
