Question

我正在编写一段能够找到用户的LATITUDE和LONGITUDE的代码，并且会在点击按钮时通过PHP保存MySQL数据库。它给了我弹出窗口的坐标，但没有将它保存到数据库。这里＆＃39;我的代码 -

我相信我在edit.php上的客户端不正确。

<?php

include_once("php_includes/database.php");
 // If not logged in - Redirect to login
if( $log_user == ""){
header("location: index.php");
exit();
 }
    ?>

   <?php

         $sql     = "SELECT * FROM users WHERE user='$log_user' LIMIT 1";
         $result  = $database->query($sql);
         while($record = $database->fetch_array($result)){
         $fn                    = $record['fname'];
         $ln                    = $record['lname'];
         $latlon                = $record['latlon'];
          }
        ?>
 <?php
  if(isset($_POST['submit'])){

        $fname                   = trim($database->escape_value(ucfirst(preg_replace('#                        [^a-zA-Z ]#i', '',$_POST['fname']))));
      $lname                   = trim($database->escape_value(ucfirst(preg_replace('#[^a-zA-Z ]#i', '',$_POST['lname']))));
       $latlon                  = trim($database->escape_value(preg_replace('#[^a-z0- 9., ]#i', '', $_POST['latlon'])));



     $sql = "UPDATE users SET
            fname             = '{$fname}',
    lname             = '{$lname}',
    latlon            = '{$latlon}',
    WHERE user        = '{$log_user}'";



           $query = $database->query($sql);
          if($database->affected_rows() == 1){
          header("location: profile.php?u=$log_user");
            exit();
           }        

              }
              }
             ?>
         <?php
            if(isset($_POST["latlon"])){// Button which updates location VIA Google Map API
    // CONNECT TO THE DATABASE
         include_once("php_includes/db_conn.php");
    // GATHER THE POSTED DATA INTO LOCAL VARIABLES

    $latlon = trim($database->escape_value(preg_replace('#[^a-z0-9.,]#i', '',  $_POST['latlon'])));

         // FORM DATA ERROR HANDLING
          if($latlon =="notSet"){
         echo "The form submission is missing values.";
            } else {
            // END FORM DATA ERROR HANDLING
           // Begin UPDATING Location data into the database
           $sql    = "UPDATE users SET
                       latlon            = '{$latlon}',
               WHERE user        = '{$log_user}'";
               $query  = mysqli_query($db_conx, $sql); 
               echo "update_done";

                }

                   }
                 ?>



       <html>
            <head>
                  <title>Edit Profile</title>

                 <script type="text/javascript" src="js/main.js"></script>

      <body>

         <div class="page_index">

         <div id="abcd"></div>


           <br/>
            <form id="edit_form"  action="edit_profile.php" method="post">


             <h4>Name</h4>

           <button class="upbtn" onClick="getLocation();locme();">Locate me now</button>    //Button which find LONG and LAT of user when user hits.
         </form>

               <?php include_once("footer_bar_1.php"); ?>
           </body>
         </html>

这是MAP API代码

       var latlon = "notSet";
       function getLocation (){
       navigator.geolocation.getCurrentPosition(getPos, getError);
           }

         function getPos(position){
         latlon = position.coords.latitude+","+position.coords.longitude;
         alert(latlon);
           }

              function getError(error){
              var locError = error.code;
              var latlon   = "notSet";
              alert(latlon);
              }

使用html，google Map API和PHP在10分钟间隔后更新位置
