Question

我正在编写数据库应用程序，但php配置告诉我：

警告：mysqli_execute（）期望参数1为mysqli_stmt，给定布尔值

我的add.php文件如下所示：

$conn=mysqli_connect ($server, $user, $password, $db);
if ( !$conn ) {
  die( 'connect error: '.mysqli_connect_error() );
}

$value1 = $_POST['country'];
$value2 = $_POST['station'];
$value3 = $_POST['stream'];
$value4 = $_POST['stream2'];
$value5 = $_POST['web'];
$value6 = $_POST['genre'];
$value7 = $_POST['desc'];


  $query = mysqli_prepare($conn, 'INSERT INTO `stations`(`station`, `country`, `stream`, `stream2`, `web`, `genre`, `desc`) 
  VALUES ($value1,$value2,$value3,$value4,$value5, $value6,$value7)');
  $stmt1 =  mysqli_prepare($conn, $query);
  /*mysqli_bind_param($query, "sssssss", $value1, $value2, $value3, $value4, $value5, $value6, $value7);*/
mysqli_execute($query);
if ( !mysqli_execute($stmt1) ) {
  die( 'stmt error: '.mysqli_stmt_error($stmt1) );
}
  /*header("Location: index.php");
  echo '<script type="text/javascript">';
    echo 'alert("your station was added!")';
    echo '</script>';*/

Answer 1

请试试这个：

if (!mysqli_query($conn,'INSERT INTO `stations`(`station`, `country`,  `stream`, `stream2`, `web`, `genre`, `desc`) 
  VALUES ($value1,$value2,$value3,$value4,$value5, $value6,$value7)'))
{
    echo("Error description: " . mysqli_error($con));
}

删除所有其他编码

Answer 2

$conn = mysqli_connect ($server, $user, $password, $db);
if ( !$conn ) {
    die( 'connect error: '.mysqli_connect_error() );
}

$value1 = $_POST['country'];
$value2 = $_POST['station'];
$value3 = $_POST['stream'];
$value4 = $_POST['stream2'];
$value5 = $_POST['web'];
$value6 = $_POST['genre'];
$value7 = $_POST['desc'];

if ($stmt = $conn->prepare("INSERT INTO stations (station, country, stream, stream2, web, genre, 'desc') VALUES (?, ?, ?, ?, ?, ?, ?")) {
    $stmt->bind_param('sssssss'. $value1, $value2, $value3, $value4, $value5, $value6, $value7);

    if ($stmt->execute() !== false) {
        // YAY
    } else {
        // Doesn't work
    }
}
