javascript - AJAX no output after evaluation through if-statements -


so i've got file index.php gives form upload image.

<!doctype html> <html>     <head>         <title>unnamed</title>         <meta name="viewport" content="width=device-width, initial-scale=1.0">          <!-- include styles -->         <link href = "bootstrap/css/bootstrap.min.css" rel="stylesheet">         <link href = "css/style.css" rel="stylesheet">          <!-- include jquery -->         <script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>         <!-- include form plugin -->         <script src="http://malsup.github.com/jquery.form.js"></script>         <!-- javascript -->          <script>              // wait dom loaded              $(document).ready(function() {                  // bind 'myform' , provide simple callback function                  $('#insert_movie').ajaxform(function() {                      $('#message').load('upload_file.php');                  });              });          </script>     </head>      <body>         <!-- message banner -->         <div id='message'></div>          <!-- insert movie database -->         <h1>add new movie list</h1>         <form id="insert_movie" action="upload_file.php" method="post" enctype="multipart/form-data">              <label for="file">filename:</label>             <input type="file" name="file" id="file"><br>             <input type="submit" name="submit" value="submit">         </form>      </body> </html>

note: might not familiar guys, i've used plug-in jquery in order easy ajax-ing. might want check link

i evaluate form via upload_file.php:

<?php error_reporting(e_all); //upload image $allow = array("jpg", "jpeg", "gif", "png");  $todir = 'images/';  if(isset($_post['submit'])){     if ( $_files['file']['tmp_name'] ) // file uploaded yet?     {         $info = explode('.', strtolower( $_files['file']['name']) ); // whats extension of file          if ( in_array( end($info), $allow) ) // file allowed         {             if ( move_uploaded_file( $_files['file']['tmp_name'], $todir . basename($_files['file']['name'] ) ) )             {                 echo "great";             }         }         else         {             // error file ext not allowed             echo 'choose file extension';         }     } }  echo "this works";  ?>

so problem nothing beside "this works" ever rendered in tags. upload performed perfectly.

all appreciated!

edit: when forget ajaxing , redirected upload_file.php, gets rendered fine...

the problem form send via ajaxform upload_file.php , should work fine in call returning expected string. server response callback function called , here call upload_file.php again without parameters , render result in div, "this works" . should use plugin following:

$('#insert_movie').ajaxform({       success: function(response) {             $('#message').html(response);        }});
