Question

Connection.php file which stored database connection code with json:

<?php
    $username = "root";
    $password = "";
    $database = "roadmap";
    $url = "localhost";

    $con = mysql_connect($url, $username , $password);
    if (!$con) {
       die('Could not connect:' . mysql_error());
    }

    mysql_select_db($database, $con) ;
    $data = array();
    // query your DataBase here looking for a match to $input
    $query = mysql_query("SELECT * FROM students");
    while ($row = mysql_fetch_assoc($query)) {
       $json = array();
       $json['Id'] = $row['Id'];
       $json['Lon'] = $row['Lon'];
       $json['Lat'] = $row['Lat'];
       $data[] = $json;
    }
    header("Content-type: application/json");
    echo json_encode($data);
    mysql_close($con);
?>

In separate file index.php:

$.getJSON("connection.php", function(data) {
    addMarker( data[0].Lon,data[0].Lat ,data[0].desc);
    addMarker(-0.13264,51.50918 , );
    addMarker( -0.12498,51.50807 , );
    center = bounds.getCenterLonLat();
    map.setCenter(center, map.getZoomForExtent(bounds) - 1);
    zoom = map.getZoom();   
});

this currently pulls the json data through and I have to use it for each individual assigning of a part from the database such as data[0].lon will get the longitude entry for the first record with in the database.

As I am going to be working with quite a few entry’s. I want to loop through the json array and then out put all records as so:

addMarker( RECORD 1 );

addMarker( RECORD 2 );

addMarker( RECORD 3 );

Can anyone help me with this.

Answer 1

use something like this

$.each(data, function(i,row){
  addMarker( row['Lon'],row['Lat'] ,row['desc'])
})
