I am trying to pass a variable from jQuery to a PHP file and I am having a difficulty in doing it.
Here is a simple HTML file of "send.html".
<html>
<head>
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$.ajax({
type: 'post',
url: 'receive.php',
data: {message : "Hello World!"}
})
.done(function(data) {
alert(data);
});
});
});
</script>
</head>
<body>
<button>Click here</button>
</body>
</html>
And I have a PHP file of "receive.php".
<?php
session_start();
if(isset($_POST['message'])){
$_SESSION['message'] = $_POST['message'];
echo $_SESSION['message'].'<br />';
} else {
echo "message not set";
}
?>
When I click the button on send.html, I get the correct alert saying "Hello World!". But when I access "receive.php" by typing the URL on my webbrowser, I get the message saying:
message not set
If I want to get "Hello World!" from receive.php, what should I do? Anybody has a solution to this problem?
Thanks.
your receive.php should be
<?php
session_start();
if(isset($_POST['message'])){
$_SESSION['message'] = $_POST['message'];
echo $_SESSION['message'].'<br />';
}else if(isset($_SESSION['message'])){
echo $_SESSION['message'].'<br />';
}else{
echo "message not set";
}
?>
