Jquery AJAX失败了

Question

I am trying to send an ID to a PHP page to update a database. First time using AJAX.

I keep getting an error. The PHP file is in the same directory

function approve(id) {

        $.smallBox({
            title : "Are you sure you would like to approve this indicator?",
            content : "<p class='text-align-right'><a href='javascript:approve_indicator(" + id + ");' class='btn btn-primary btn-sm'>Yes</a> <a href='javascript:void(0);' class='btn btn-danger btn-sm'>No</a></p>",
            color : "#296191",
            //timeout: 8000,
            icon : "fa fa-bell swing animated"
        });


}

function approve_indicator(id){
        $.ajax({
              url: '/approve_indicator.php',
              type: 'post',
              data: 'id='+id,
              success: function() 
              {
                  alert('success, server says '+output);

                  location.reload();

              }, error: function()
              {
                  alert('something went wrong, rating failed');
              }
        });

}

this is the PHP. Not sure if it matters

$id = $_POST['id'];
$update_indicator = $con->preapre("UPDATE indicators SET approved = ? WHERE indicator_id = ?");
$update_indicator->execute(array(1,$id));

Answer 1

Your PHP code contains preapre instead of prepare. This is likely giving you unwanted results. Also, using a web tool such as Firebug lets you see the AJAX responses. If your PHP errors are displayed, the response will tell you what is wrong with your PHP code.
