我试图通过php将所有Json数据放入我的Mysql数据库中，我在这个json对象中有我所有的手机联系人详细信息，但它只在我的数据库中插入最后一个电话联系人详细信息，请帮助我，因为我有已经发布了一个问题，但没有找到满意的答案。我调试了应用程序，它包含了makehttprequest（.....）函数参数中的所有联系人详细信息，但只将最后一个联系人详细信息插入到数据库中。
我的php代码如下：
$response = array();
// check for required fields
if (isset($_POST['name']) && isset($_POST['id']) && isset($_POST['phone'])&& isset($_POST['email'])) {
$id = $_POST['id'];
$name = $_POST['name'];
$phone = $_POST['phone'];
$email = $_POST['email'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("INSERT INTO crm(id, name, phone, email) VALUES('$id', '$name', '$phone', '$email')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Product successfully created.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>
我在调试应用程序时复制的json对象是：
[id = 85，name = ，phone = ，email = 2，id = 106，name = ，phone = ，email = 2，id = 93， name = ，phone = ，email = 2，id = 62，name =。，phone = * 100＃，email = 2，id = 104，name = 00，phone = 00，email = 2 ，id = 90，name = 03005103877，phone = 03005103877，email = 2，id = 26，name = 03005580234，phone = 03005580234，email = 2，id = 154，name = Wajaht，phone = + 923336124178，email = 2， id = 230，name = Yasir Altaf，phone = 03215169284，email = 2，id = 55， name = Zafar Abbas，phone = 03016775189，email = 2 ]
但它插入了最后一个联系人详细信息，名称= Zafar Abbas，电话= 03016775189，电子邮件= 2但是我想一次性插入所有细节，请帮助我谢谢

答案 0 :(得分：0)
问题在于：
for(int i = 0; i < contactArray.size(); i++){
SavingContacts contact = contactArray.get(i);
params.add(new BasicNameValuePair("id", contact.id));
params.add(new BasicNameValuePair("name", contact.name));
params.add(new BasicNameValuePair("phone", contact.phone));
params.add(new BasicNameValuePair("email" , contact.email ));
}
JSONObject jsonObject= new JSONParser().makeHttpRequest(URL, "POST", params);
您只在循环之后发出请求，这将解释为什么您只有INSERT最后一个值。
在循环中移动请求，以便在每次迭代时执行插入：
bool isSuccessful;
for(int i = 0; i < contactArray.size(); i++){
SavingContacts contact = contactArray.get(i);
params.add(new BasicNameValuePair("id", contact.id));
params.add(new BasicNameValuePair("name", contact.name));
params.add(new BasicNameValuePair("phone", contact.phone));
params.add(new BasicNameValuePair("email" , contact.email ));
//INSERT at each iteration
JSONObject jsonObject= new JSONParser().makeHttpRequest(URL, "POST", params);
if(jsonObject != null){
try {
int success = jsonObject.getInt(TAG_SUCCESS);
if (success == 1) {
Log.d("debug", "Contact Id# " + contact.id +" Inserted");
} else {
Log.d("debug", "Contact Id# " + contact.id +" FAILED");
}
isSuccessful = true;
} catch (JSONException e) {
Log.d("exception","exc "+e);
Log.d("create","lpc");
isSuccessful = false;
}
}else{
Log.d("debug", "json is null");
isSuccessful = false;
}
}
return isSuccessful;
