im working on a script that sends a few data stored using GET to a PHP script(process it then put it into database).

here's the ajax script , im using jQuery ajax (i have included the latest jQuery script)

function send(){
  $.ajax({
     type: "GET",
     url: "http://examplewebsite.com/vars/parse.php",
     data: "id=" + id + "&purl=" + purl + "&send" + "true",
     cache: false,
     success: function(){
       alert("Sent");

     }
  });
}

id and purl are JavaScript variables .

send() function is set in :

<a href="#" onclick="send()">Send</a>

PHP code:

<?php

//Connect to database
include ("config.php");

//Get the values
$id = $_GET['id'];
$purl = $_GET['purl'];
$send = $_GET['send'];

if ($send == 'true') {

    $insertdata = "INSERT INTO data (id,purl,send) VALUES ('$id','$purl',+1)";
    mysql_query($insertdata) or die(mysql_error());
} else {
    //do nothing
}
?>

when i type http://examplewebsite.com/vars/parse.php?id=123&purl=example&send=true it works, the php injects the data into the database as i wanted but when i use send() and wanted to use ajax to send the data, failed.

Is there any mistakes that im making?

You're missing the = after send,

function send(){

  $.ajax({
     type: "GET",
     url: "http://examplewebsite.com/vars/parse.php",
     data: "id=" + id + "&purl=" + purl + "&send=" + "true",
     cache: false,
     success: function(){
       alert("Sent");

     }
  });
}

should fix it, also. post more information about your javascript. We just have to assume id and purl are filled out. Did you try debugging them (if this doesn't work).

Also, debug the URL that is requested, you can use firefox or chrome dev-tools for this. What url is being send to the PHP page and is it correct
