Trouble with $.post

Question

I am trying to insert some values into an sql database.

I am using

<input type="text" name="message" id="message"  />
<input type="image" src="boca.png" onClick="send();" />

to get the value and

function send(){

var mess = $('#message').val('');   
var dataString = 'message:'+ mess;  
$.ajax({  
  type: "POST",  
  url: "atuamae.org/send.php",  
  data: dataString,  
  success: function() {  
    $('#message').val('');
  }  
});  }

to send it to the php file and in the php file:

$message = $_GET['message'];

I think the error occurs either in sending or in the way the var dataString is encoded

Answer 1

Simply enough, you're using the HTTP POST method, not the HTTP GET method, so you need to use $_POST rather than $_GET on the PHP side.

Answer 2

If you are using post you must use $_POST['message'] not $_GET['message']

Answer 3

You are setting the content of the '#message' element

Change

var mess = $('#message').val('');  

to

var mess = $('#message').val();

And also, yes you are using POST but trying to retreive the value through GET

Answer 4

try:

var mess  =   document.getElementById('message').value;
var dataString = 'message='+ mess;
