-map is a description of the view of the earth viewed from above, in this paper will be explained about the stages in making the form input data into the map.

buatlah sebuah database dengan mengikuti sytax dibawah ini :

create database datapeta;
use datapeta;
create table tempat(
    id_tempat int not null auto_increment primary key,
    latlng varchar(100) not null,
    nama_tempat varchar(50) not null,
    keterangan_tempat text
    )

setelah membuatnya, silakan diperiksa di phpmyadmin, pasti akan tampil data seperti gambar dibawah ini :

selanjutnya buat sebuah file php dengan nama peta.php, codingnya dapat dilihat dibawah ini :

<html>  
  <head>  
   <title></title>  
  </head>  
  <body>  
  <div id="map_canvas" style="width:70%; height:70%;">       
   </div>  
  </body>  
  <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>  
  <script type="text/javascript">  
  var infowindow = null;  
  (function() {  
   initialize();  
     
  })();  
    function initialize() {   
       var sites = [  

    ];
        var centerMap = new google.maps.LatLng(5.041453040397738,97.32267737388611);
        var myOptions = {  
        
          zoom: 14, 
          center: centerMap, 
          mapTypeId: google.maps.MapTypeId.ROADMAP   
        }  
    
       var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); 
    
        setMarkers(map, sites);  
        setAction(map);  
        infowindow = new google.maps.InfoWindow({  
            content: "loading..."  
          });  
    
      var bikeLayer = new google.maps.BicyclingLayer();  
        bikeLayer.setMap(map); 
          
     }  

        function setMarkers(map, markers) {  
        for (var i = 0; i < markers.length; i++) {  
          var sites = markers[i];  
          var siteLatLng = new google.maps.LatLng(sites[1], sites[2]);  
          var marker = new google.maps.Marker({  
            position: siteLatLng,  
            map: map,  
            title: sites[0],  
            zIndex: sites[3],  
            html: sites[4]  
    
          });  
    
          var contentString = "Some content";  
          google.maps.event.addListener(marker, "mouseover", function () {  
              
            infowindow.setContent(this.html);  
            infowindow.open(map, this);  
          });  
        }  
      }  
    
        function setAction(map){  
            
          google.maps.event.addListener(map, "rightclick", function(event) {  
    
          if(confirm("Tandai Titik Ini? (klik pada tanda yang muncul untuk melihat pilihan)")){  
            var lat = event.latLng.lat();  
            var lng = event.latLng.lng();
            var form = '<h4>Tambah Data</h4><form id="formtambahdata" method="post" action="save.php"><br><input type="text" id="nama" placeholder="nama tempat" name="nama"><br><textarea id="keterangan" name="keterangan" placeholder="Isi Keterangan tempat"></textarea><br><input type="text" id="latlng" name="latlng" value="'+lat+','+lng+'"><br><input type="submit" value="save"></form>'; 
              
            var siteLatLng = new google.maps.LatLng(lat, lng);  
            var marker = new google.maps.Marker({  
                position: siteLatLng,  
                map: map,  
                title: "add data",  
                zIndex: 100,  
                html: form 
    
              });  
             google.maps.event.addListener(marker, "mouseover", function () {  
                  
                infowindow.setContent(this.html);  
                infowindow.open(map, this);  
              });  
          }   
        });  
        }  
  </script>  
  </html>

berdasarkan coding diatas akan didapat hasil seperti ini :

buat sebuah file php dengan nama save.php dan ikuti coding berikut ini :

<?php  
 mysql_connect('localhost','root',''); 
 mysql_select_db('datapeta'); 
 $nama_tempat = $_POST['nama'];  
 $keterangan = $_POST['keterangan'];
 $latlng = $_POST['latlng'];
 $query = "insert into tempat (nama_tempat,keterangan_tempat,latlng) values('$nama_tempat','$keterangan','$latlng')"; 
 if(mysql_query($query)){  
      header('location:peta.php');
      }  
 ?>

pada baris yang ditandai dibawah ini :
masukan coding php berikut :

    <?php  
           mysql_connect('localhost','root','');  
           mysql_select_db('datapeta');  
           $query="select * from tempat";  
           $datas = mysql_query($query);  
           while ($data=mysql_fetch_array($datas)) {  
             ?>  
             ["<?php echo $data['nama_tempat'];?>", <?php echo $data['latlng']; ?> ,1, "<h4><?php echo $data['nama_tempat'];?></h4><p><?php echo $data['keterangan_tempat'];?></p>"],  
             <?php  
           }  
         ?>
