我正在使用PHP / MYSQL在服务器中编写一个带有数据库的简单Android应用程序。以前我的注册表格数据会被插入到表格中。但是，当我从此表中创建与另一个表的关系时，问题就开始了，数据不再被插入。我使用了一些定制的排球库来进行网络连接，因此它不是问题。我无法找到确切的错误，但我确实知道php文件存在问题。我正在使用PDO，并且已使用SELECT方法将数据插入到外键列中。 Table 1 Structure Table 2 Strucutre PHP CODE如下：
<?php
require 'init.php';
error_reporting(E_ALL);
$category = $_POST['category'];
$ownername = $_POST['ownername'];
$ownerno = $_POST['ownerno'];
$pricing=$_POST['pricing'];
$description=$_POST['description'];
$whatsappno=$_POST['whatsappno'];
$email=$_POST["email"];
$response = array();
$response["SUCCESS"] = 0;
//get database connection
$databse = new Database();
$con = $databse->getConnection();
try
{
$STH = $con->prepare("INSERT INTO Profile (Category_type, Full_name, Personal_no, Pricing, Description, Whatsapp_no, userid) value (?,?,?,?,?,?, (SELECT userid FROM users where email=$email)");
$STH->bindParam(1,$category);
$STH->bindParam(2,$ownername);
$STH->bindParam(3,$ownerno);
$STH->bindParam(4,$pricing);
$STH->bindParam(5,$description);
$STH->bindParam(6, $whatsappno);
$STH->execute();
if ($STH->rowCount() > 0) {
$response["SUCCESS"] = 1;
$response["message"]="User profile is complete now !!";
}else{
$response["SUCCESS"]=2;
}
}catch(PDOException $e){
echo $e->getMessage();
}
echo json_encode($response);
?>

答案 0 :(得分：0)
您进行了这些更改
替换：
(SELECT userid FROM users where email=$email)
到
(SELECT userid FROM users where email=?)
并将此行添加到$ STH行的末尾
$STH->bindParam(7, $email);
