Question

我正在开发一款Android应用，但我实际上是新手。我试图将一些数据发布到我的数据库，但我不知道我的代码出了什么问题。我正在使用齐射库来处理请求和后端的php / mysql。我认为问题在于我的PHP代码，因为我正在尝试将我的数据保存到表格＃34; social＆＃34;在表用户中具有对uid的外键user_id引用。我不知道我是否正确解释我的问题，但下面是我的代码。对不起英语不好并提前致谢

function.php

    public function storeSocial( $itemName, $email, $password, $URL,$note ){
    $em = $_SESSION['email'];
    $query = mysql_query("Select * from users where email = '$em'");
    $row = mysql_fetch_array($query);
    if($row)
    {
        $id = $row['uid'];
    }
    else return false;

    $res = mysql_query("INSERT INTO social ( user_id, ItemName, email,     password, URL,note)
    VALUES( '$id','$itemName', '$email', '$password', '$URL', '$note')" );
    // check for successful store
    if ($res) {
       return true;
    } else {
        return false;
    }

的index.php

<?php
session_start();

if (isset($_POST['tag']) && $_POST['tag'] != '') {
// get tag
$tag = $_POST['tag'];

// include db handler
require_once 'include/DB_Functions.php';
$db = new DB_Functions();

// response Array
$response = array("tag" => $tag, "error" => FALSE);
if ($tag == 'social')
{
    // Request type is Saving data
    $itemName = $_POST['ItemName'];
     $URL = $_POST['URL'];
    $email = $_POST['email'];
    $password = $_POST['password'];
    $note = $_POST['note'];

    $data = $db ->storeSocial($itemName, $email, $password, $URL, $note);
    // check for successful store
     if ($data)
    {
        // user stored successfully
        $response["error"] = FALSE;
        echo json_encode($response);
    }
    else {
        // user failed to store
        $response["error"] = TRUE;
        $response["error_msg"] = "Failed to store";
        echo json_encode($response);
    }
}

我无法在我的PHP脚本中发布任何数据
