Simple PHP upload form not working_问答_开发者

I seem to run into so many issues when dealing with writing to directories. If someone could please look over this script, and tell me why it's not working, I'd be so appreciative.

Upon uploading the file from the form, I don't get anything.. It doesnt output any errors, it simply just refreshes.

Thanks, Lea

<?php include ('config.php');
 if( isset($_POST['submit']) ) {

$target = ''.$_SERVER['DOCUMENT_ROOT'].'/images/';
$target = $target . basename( $_FILES['photo']['name']) ;
$url = basename( $_FILES['photo']['name']) ;

if(move_uploaded_file($_FILES['photo']['tmp_name'], $target)) {
$moved =  "File has been moved to location $target";

$name = mysql_real_escape_string($_POST['photona开发者_Python百科me']);
mysql_query("INSERT INTO photos (photo_name, photo_image) VALUES ('$name',  '$url' )") or die(mysql_error());
$success = "Photo has been added!";

  } else {

$moved = "File has not been moved to $target";
$success = "Failed to upload:(";

  }

} ?>

            <br />

        </tr>
        <tr>
          <td valign="top">Photo:</td>
          <td valign="top">
  <input type="file" name="photo"><br />
            <br />
            </td>
        </tr>
      </tbody>
    </table>
    <input type="submit" value="submit" />
  </form>
</div>
</body>
</html>

Without checking the PHP code for errors, the first thing that stands out is that this:

isset($_POST['submit'])

always returns false. The input type="submit" must have the name attribute "submit" in order to be sent:

<input type="submit" value="submit" name="submit" />

Here is mistake, in submit button use like this :

<input type="submit" value="submit" name="submit" />

Ok done

<?php 
if( isset($_POST['submit']) ) {
 $target = 'images/';
 echo $target = $target . basename( $_FILES['photo']['name']) ;

 if(move_uploaded_file($_FILES['photo']['tmp_name'], $target)) {
  $moved =  "File has been moved to location $target"; 
  $success = "Photo has been added!";
 } 
 else { 
 $moved = "File has not been moved to $target";
 $success = "Failed to upload:(";
  }
} 
?>
