PHP Code:

<textarea name="comment_text[]" rows=3 cols=40></textarea>
<input type="hidden" name="post_id[]" value="<?= post_id;?>" /> 


When your form is posted, you can loop through the arrays like this:

PHP Code:

$posts = $this->input->post('post_id');  //returns an array!!
$comments = $this->input->post('comment_text');  //also returns an array
foreach ($posts as $key=>$post_id) {
  if (empty($comments[$key]) continue;  //don't save empty comments fields
  $data = array(
    'post_id' => $post_id,
    'comment' => $comments[$key]
  );
  $this->db->insert('table',$data);
}

Your view builds up a series of forms (within a foreach {  }  loop).
All forms have the same name: post_comment.
In your javascript function do_something(), you submit the form with the name post_comment. Since all forms have that name, only the first one is posted.

Now my question is: when the user hits the Enter key, do you want all comment-forms to be posted, or just the one where the user has filled-in some text and hit Enter?

PHP Code:

//html header etc.

<?php foreach($result as $row) : ?>
 
// info about this post

<div>
<?php
echo form_open('regcheck/comment_insert',array('name'=>'comments_form[]','id'=>'form_' . $row->post_id));
echo form_hidden('post_id[]', $row->post_id);
echo form_input('post_comment[]',NULL,'size="40" class="ta-comment"');
echo form_close();
?> 
</div>
 
<?php endforeach; ?>

<script>

 $('.ta-comment').keypress(function(event) {
  var frm_id = $(this).parents('form').attr('id');
  if (event.which == 13 ) {
   event.preventDefault();
   $('#' + frm_id).submit();
  } 
  
 });  
 
</script>

//html footer etc. 


Take a good look at the Jquery script at the end. This script triggers the submit event only for the form where the user has typed text and hit Enter.

Now in your controller, put this code to fetch the posted values:

PHP Code:

$post_id = $this->input->post('post_id[0]');
$post_comment = $this->input->post('post_comment[0]');
//insert these values into your database 


The reason why you need to add [0] after the post_id and post_comment variables, is that these are arrays. Since only one form is posted, this array contains only one key (0).
