JQuery Ajax

[jnicholls92]

// JavaScript Document
function JNChatroom_Submit() {
	var field_a = $("#chatareabox").val();
	$.ajax({
		type: "POST",
		url: "php-script.php?fun=post",
		data: "message="+field_a,
		success: function(done) {
			$("#chatareabox").val('');
		}
		error: function(e) {
			alert("Error: "+e);
		}
	}) 
}

For some reason i cant get this code working, it used to work but now it wont i cant find the problem and i have been looking for 2 hours. Please help

This is for a chatroom, after typeing there post they click a button 'onClick="JNChatroom_Submit()" ' but nothing happens, not alert or clearing of the textarea, there is also no submition to my database.

below is my PHP

PHP Code:

if($MySQL){

    if($_GET['fun'] == 'post'){
        $POST = mysql_query("INSERT INTO chatroom (user_id, post) VALUES ('".$User['id']."', '".$_POST['message']."')");
    }

}

You should start debugging

There's at least a simple syntax error. A missing comma after the success callback

Then you are mixing a POST request with a GET request ... I don't know if jQuery is tolerant about that, but it's not good habit. Hint: Appending a parameter with ? to the URL usually will make the request a GET request

Mixing them together seems to work with chatrooms i have created in the past, all it does is looks thought the PHP page to find the correct code

PHP Code:

<?PHP
if($_GET['fun'] == 'post'){
 // Submit
}
if($_GET['fun'] == 'retreave'){
 // Retrive Data
}
?>

This seems to work and does the job very well rather then making many different pages it read the code you ask it to.

How do you access the second parameter "message" in PHP then? With $_GET['message'] or $_POST['message']?

[jnicholls92]

$_POST['message']

GET And POST are used in different ways

$_GET['id'] is in the URL index.php?id=1
$_POST['message'] has been posted from a form within the last page.

PHP Code:

 if($_GET['fun'] == 'submit'){
  mysql_query("INSERT INTO chatroom (user_id, post) VALUES ('".$_SESSION['abc123']."', '".$_POST['message']."'");
}
if($_GET['fun'] == 'retrive'){
 echo $_POST['message'];
} 


my chatroom is finished and i would quite happyly show you it, please email me jnicholls92@hotmail.co.uk
