Question

我一直试图将地图坐标传递给MySQL数据库，但我不知道如何传递我拥有的代码的数据。我昨晚尝试了，但它显示了许多错误....有谁可以帮助我如何解决问题...
这是我的MapActivity代码.... 如果有人能帮助我，我会很感激吗？我想使用php脚本连接到MySQL，但我不介意任何人都可以提供更简单的连接数据库的解决方案

创建表格

<?php
//this opens the connection to the database you need to change this for your database
$con = mysqli_connect("http://localhost/phpmyadmin","root","password", "root");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

    $sql = "CREATE TABLE data
    (
    long varchar(30),
    lat varchar(30)
    )";

// Execute query
mysqli_query($con, $sql);

mysqli_close($con);
?>

的GetList

<?php
ini_set("display_errors", 1);
error_reporting(E_ALL);
// This opens the connection to the database you need to change this for your database.
$con = mysqli_connect("http://localhost/phpmyadmin","root","password", "root");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

// Retrieve all the data from the "data" table.
$result = mysqli_query($con, "SELECT * FROM data")
or die(mysqli_error());  

// Initialise contacts array to hold our data.
$data = array();

// Add each row to contacts array.
while($row = mysqli_fetch_assoc($result)){
    $data[] = $row;
}

// Pring data as json string.
print(json_encode($data));

// Close DB connection.
mysqli_close($con);
?>

插入

<?php
//this opens the connection to the database you need to change this for your database
$con = mysqli_connect("http://localhost/phpmyadmin","root","password", "root");
if (!$con)
  {
  die('Could not connect: ' . mysqli_error());
  }

mysqli_query($con, "INSERT INTO data (long, lat)
VALUES ('".$_POST['Description']."', '".$_POST['long,lat']."')");

mysqli_close($con);
?>
