Question

无法弄清楚为什么我的ajax代码没有将数据发送到php文件。已经尝试了很多东西，但它似乎没有用。请有人帮帮我。我的HTML代码：

$password = "password";
$dbname = "testdb";


$conn = mysqli_connect($servername, $username, $password, $dbname);

if (!$conn) {
die("Connection failed: " . mysqli_error($conn));
} 

 $num= (int)$_POST["params"];
 $str = $num;
 $tempid = substr_replace($str,"T",0);
 echo $str;
$sql = "INSERT INTO `test` (`disliked`) VALUES ('$num')";
if (mysqli_query($conn, $sql) === TRUE) {
echo "New record created successfully";
} 
else {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

mysqli_close($conn);
?>

Answer 1

您的代码$route['steam-(:any)/(:any)'] = "main/stream/$1/$2"; $route['movie-(:any)/(:any)'] = "main/movie/$1/$2"; $route['drama-(:any)/(:any)'] = "main/drama/$1/$2";中存在错误。应为var params ={id : (this).id};（并将var params ={id : $(this)[0].id};的所有实例更改为(this).id）

并且您传递了$(this)[0].id参数，因此在服务器端，将id更改为$_POST["params"];

$_POST["id"];
