I am currently using the JQuery ajax function to call an exterior PHP file, in which I select and add data in a database. Once this is done, I run a success function in JavaScript. What's weird is that the database is updating successfully when ajax is called, however the success function is not running. Here is my code:
<!DOCTYPE html>
<head>
<script type="text/javascript" src="jquery-1.6.4.js"></script>
</head>
<body>
<div onclick="addtask();" style="width:400px; height:200px; background:#000000;"></div>
<script>
function addtask() {
var tid = (Math.floor(Math.random() * 3)) + 1;
var tsk = (Math.floor(Math.random() * 10)) + 1;
if(tsk !== 1) {
$.ajax({
type: "POST",
url: "taskcheck.php",
dataType: "json",
data: {taskid:tid},
success: function(task) {alert(task.name);}
});
}
}
</script>
</body>
</html>
And the PHP file:
session_start();
$connect = mysql_connect('x', 'x', 'x') or die('Not Connecting');
mysql_select_db('x') or die ('No Database Selected');
$task = $_REQUEST['taskid'];
$uid = $_SESSION['user_id'];
$q = "SELECT task_id, taskname FROM tasks WHERE task_id=" .$task. " LIMIT 1";
$gettask = mysql_fetch_assoc(mysql_query($q));
$q = "INSERT INTO user_tasks (ut_id, user_id, task_id, taskstatus, taskactive) VALUES (null, " .$uid. ", '{$gettask['task_id']}', 0, 1)";
$puttask = mysql_fetch_assoc(mysql_query($q));
$json = array(
"name" => $gettask['taskname']
);
$output = json_encode($json);
echo $output;
Let me know if you have any questions or comments, thanks.
