插入查询到不工作

Question

我试图将数据插入到一个在线数据库MySql在线MySQL数据库，我用这个查询在几个月前，现在它似乎没有工作，

我的表格：

$name = "Hilary"; 
$number = "768"; 
$orderss = "Rice x1"; 
$location = "Chilenje"; 

$con= mysqli_connect($host,$user,$pass,$db); 

$query= "insert into orders values('".$name."','".$number."','".$orderss."','".$location."');"; 

$result= mysqli_query($con,$query); 

if(!$result) 
{ 
    $response = array(); 
    $code= "reg_false"; 
    $message="Error Placing Order..."; 
    array_push($response,array("code"=>$code,"message"=>$message)); 
    echo json_encode(array("server_response"=>$response)); 

} 
else 
{ 
    $response = array(); 
    $code= "reg_true"; 
    $message="Order Successful,Please wait for our call..."; 
    array_push($response,array("code"=>$code,"message"=>$message)); 
    echo json_encode(array("server_response"=>$response)); 

} 

mysqli_close($con); 

?> 

当我运行这种形式我得到服务器响应的“错误下单”部分和值不inserted.Please帮我

让您$query很简单的像这样的，如果你插入的所有列你的表

$stmt = $conn->prepare("INSERT INTO orders VALUES (?, ?, ?, ?)"); 
$stmt->bind_param("siss", $name, $number, $orderss, $location); 

或者如果你插入到特定的列，您可以用您的实际列名

$stmt = $conn->prepare("INSERT INTO orders (column_name1, column_name2, column_name3, column_name4) VALUES (?, ?, ?, ?)"); 
$stmt->bind_param("siss", $name, $number, $orderss, $location); 

或者我还修改当前的代码，这样你可以在你结束一个测试替换column_name*使用还有一点"siss"的论据是4种不同类型i - integer, d - double, s - string, b - BLOB

<?php 
$servername = "localhost"; 
$username = "username"; 
$password = "password"; 
$dbname = "myDB"; 

$name = "Hilary"; 
$number = "768"; 
$orderss = "Rice x1"; 
$location = "Chilenje"; 

// Create connection 
$con = new mysqli($servername, $username, $password, $dbname); 

// Check connection 
if ($con->connect_error) { 
    die("Connection failed: " . $con->connect_error); 
} 

// prepare and bind 
$stmt = $conn->prepare("INSERT INTO orders VALUES (?, ?, ?, ?)"); 
$stmt->bind_param("siss", $name, $number, $orderss, $location); 

if($stmt->execute()) { 
$stmt->execute(); 
    $response = array(); 
    $code= "reg_true"; 
    $message="Order Successful,Please wait for our call..."; 
    array_push($response,array("code"=>$code,"message"=>$message)); 
    echo json_encode(array("server_response"=>$response)); 
} else { 

    $response = array(); 
    $code= "reg_false"; 
    $message="Error Placing Order..."; 
    array_push($response,array("code"=>$code,"message"=>$message)); 
    echo json_encode(array("server_response"=>$response)); 

} 
$stmt->close(); 
$con->close(); 
?>
