来自php mysql的Android响应代码200，但不在数据库中创建条目
问题描述：
I am sending data from my android app form to php mysql server and from server i am getting response code 200 but failed to make any entries into database.
Here is my php file where i am sending POST variables
<?php
$host='localhost';
$uname='root';
$pass='pass';
$db='App';
$con=mysqli_connect($host,$uname,$pass,$db);
$First_Name=$_POST['First_Name'];
$Last_Name=$_POST['Last_Name'];
$Phone=$_POST['Phone'];
$Mail_ID=$_POST['Mail_ID'];
$Password =$_POST['Password'];
$La=$_POST['La'];
$Lo=$_POST['Lo'];
$Ac=$_POST['Ac'];
$Pro=$_POST['Pro'];
if($con){
echo "Connected Successfully to database $First_Name "; //Print Variable to Check that file is getting inputs.Its Working.
}
else{
echo 'Failed To Connect to database ';
}
$sql="INSERT INTO `mobile_App`(`First_Name`, `Last_Name`, `Phone`, `Mail_ID`, `Password`, `La`, `Lo`, `Ac`, `Pro`)
VALUES ($First_Name,$Last_Name,$Phone,$Mail_ID,$Password,$La,$Lo,$Ac,$Pro)";
if(mysqli_query($con,$sql)){
echo 'Data Inserted Successfully';
}
else{
echo "ERROR: could not able to execute $sql.".
mysqli_error($con) ;
}
mysqli_close($con);
?>
This is my Java File
public class Sending_Data_To_Server extends AsyncTask{
String Lo,La,Ac,Pro,First_Name,Last_Name,Phone,Mail_ID,Password;
BufferedReader reader;
@Override
protected String doInBackground(String... params) {
//Variables
First_Name=params[0];
Last_Name=params[1];
Phone=params[2];
Mail_ID=params[3];
Password=params[4];
Lo=params[5];
La=params[6];
Ac=params[7];
Pro=params[8];
Log.d("SEND DATA VALUES",First_Name+Last_Name+Lo+La+Phone);
try {
String data= URLEncoder.encode("First_Name","UTF-8")+ "=" +URLEncoder.encode(First_Name,"UTF-8");
data+= "&" +URLEncoder.encode("Last_Name","UTF-8")+ "=" +URLEncoder.encode(Last_Name,"UTF-8");

data+= "&" + URLEncoder.encode("Pro","UTF-8")+ "=" +URLEncoder.encode(Pro,"UTF-8");
URL url=new URL("test/Android/Data/data.php"); // can't post complete url due to restriction to new users
HttpURLConnection connection= (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoInput(true);
connection.setDoOutput(true);
//For POST Only - Begin
connection.setDoOutput(true);
OutputStream os=connection.getOutputStream();
BufferedWriter writer=new BufferedWriter(new OutputStreamWriter(os,"UTF-8"));
writer.write(data);
writer.flush();
writer.close();
os.close();
connection.connect();
//For POST Only End
int responseCode=connection.getResponseCode();
Log.d("Sending Class----","POST RESPONSE CODE "+responseCode);
if (responseCode==HttpURLConnection.HTTP_OK){
//Success
reader=new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuffer response=new StringBuffer();
while((inputLine=reader.readLine())!=null){
response.append(inputLine);
}
reader.close();
//Print Result
Log.d("SENDING CLASS----",response.toString());
}
else{
Log.d("SENDING CLASS---","POST did not work");
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return "DATA SUBMITTED";
}
}

And my Database structure Rows Where I want to insert app data
Till now i have tried so many tutorials and guide and most of the places i have seen HttpClient which is depreciated so i am working with only HttpUrlConnection and as server returned status code 200 i think its some fault in php mysql file but not sure.
As @Adam Forbis suggest to print mysql error and check that value is getting by php file.So i did and i edit my PHP file to get those details and now i m updating logcat with mysql error

Maybe try as follow in you're php file (replace you're $sql var by this one):
$sql="
INSERT INTO `mobile_App`
(
`First_Name`,
`Last_Name`,
`Phone`,
`Mail_ID`,
`Password`,
`La`,
`Lo`,
`Ac`,
`Pro`
)
VALUES (
'".$First_Name."',
'".$Last_Name."',
$Phone,
'".$Mail_ID."',
'".$Password."',
$La,
$Lo,
$Ac,
'".$Pro."'
)
;";
This is also the same answer at f_anto, but i confirm that you must have the single quote arround you're strings. (i only prefere write '".$var."' at '$var')
this work perfectly for me (similar code) for testing you're problem :
<?php
$db = mysqli_connect("host", "userLogin", "userPwd", "dbName");
$id = 999;
$idc = 1;
$idd = 0;
$p = "gpog@email.com";
$la = 15478.12;
$l = 0;
$sql="
INSERT INTO `table`
(
`field1`,
`field2`,
`field3`,
`field4`,
`field5`,
`field6`
)
VALUES (
$id,
$idc,
$idd,
'".$p."',
$la,
$l
)
;";
mysqli_query($db, $sql);
var_dump(mysqli_error($db));
答
For the value of inserting query you should make like this (add quote in each value)
$sql="INSERT INTO mobile_App(First_Name,Last_Name,Phone,Mail_ID,Password,La,Lo,Ac,Pro)
VALUES ('$First_Name','$Last_Name','$Phone','$Mail_ID','$Password','$La','$Lo','$Ac','$Pro')";
答
Use this Async task instead to call php api.
public static class backgroundTask extends AsyncTask<String, String, String[]> {
@Override
protected void onPreExecute() {
//do something before putting values in database
}
@Override
protected String[] doInBackground(String... f_url) {
//call php api here with the arguments
String url = "YOUR_PHP_API_URL_WITH_ARGUMENTS";
HttpClient client = new DefaultHttpClient();
try {
client.execute(new HttpGet(url));
} catch (IOException e) {
e.printStackTrace();
}
return f_url;
}
@Override
protected void onPostExecute(String[] f_url) {
//do something after putting values in database
}
}
Also, make changes in your php api. Make it like this. I removed single quotes.
$sql="INSERT INTO mobile_App(First_Name,Last_Name,Phone,Mail_ID,Password,La,Lo,Ac,Pro)
VALUES ($First_Name,$Last_Name,$Phone,$Mail_ID,$Password,$La,$Lo,$Ac,$Pro)";
