How to reload a page in jquerymobile? - php

In My Project I am having some javascript to implement my work, but it is not taking when I am starting the page,but it is working after reloading the page.
Here is the code:
<?php
require_once"session.php";
$slat =$_GET['slat'];
$slang =$_GET['slang'];
$elat =$_GET['elat'];
$elang =$_GET['elang'];
?>

In the above I am having body onload it is not working at the first time after refreshing only it is working.

Here is the answer:
Before You are calling to this page You have to specify in href like the following
assume that you are having the following link to load:
sample
here `href="external" You have to specify otherwise it wont work.....

Always empty $_POST

I'm trying to save a Google Maps Marker's coordinates to my database after the user placed the Marker. When I send the coordinates to the server, I always receive an empty $_POST array.
Where did I go wrong?
Here's my index.php:
<!DOCTYPE html>
<html>
<head>
<title>MyMap</title>
<meta charset="UTF-8">
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">

center: new google.maps.LatLng(46.2428219,20.14682)
};
map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng);
var lat = event.latLng.lat();
var lng = event.latLng.lng();
$.ajax({
type: "POST",
url: "index.php",
data: lat,
success: function (data) {
console.log(data);
}
});
});
function placeMarker(location) {
var marker = new google.maps.Marker({
position: location,
map: map
});
map.setCenter(location);
}
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="result">
<?php

} else {

}
?>
</div>

Add a key to your data?
data: {'lat':lat}
Try something like this:
var lat_value = event.latLng.lat();
var lng_value = event.latLng.lng();
$.ajax({
type: "POST",
url: "index.php",
data: {lat:lat_value},
success: function (data) {
console.log(data);
}
});
In your index.php script use:
$lat=$_POST['lat'];

The <br /> in addMarker() function is causing the problem it and the (& ) are redundant.

Try
echo "addMarker($lat, $lon);\n";

I think the problem is in the query of the INNER JOIN.
Your select query is very limiting. You have only selected two fields in the two tables and the two fields you are trying to join on have been left out of your selection. Try using select * from both the tables and rectify the typos and you will be good to go
If i look at your query there is a typo:
SELECT lattitude, longiude FROM user u
INER JOIN village v
ON u.village = v.id
This:
longiude => longitude

Getting data in a text file after updating it on highcharts but initially retrieving from csv file

I am actually trying to do exactly what has been done in this example "http://jsfiddle.net/BrLp7/" but unfortunately not able to perform this task when retrieving data from csv file. Below is my code which doesn't output anything and when we click on a point in a given example the resulting graph has to be stored in some text file in this form 5,10,13 if last point was clicked.
