In the comment.php file the values are available in the $_POST array.

$_POST['comment'] // -> what the user wrote in the textarea.

first in comment.php use print_r($_POST) and check data is get or not.

and you use post method to send data so you can get value using $_POST['field_name'].

and try to make html,javascript and php code like this:

<html>
<script type='text/javascript'>
function submitform(){
   document.getElementById('myform').submit();
}
</script>
<form id='myform' action='comment.php' method='post'>                       
<tr>
 <td><img src='photos/<?php echo $file;?>' alt='<?php echo $file;?>'><br></td>
  :
  :
 </tr>
</form>
</html>
