Let's take a look at the view:
<div class="post-body">
<hr>
<?php echo form_open('/posts/delete/'.$posts['id']);?>
<?php if($this->session->userdata('user_id')==$posts['user_id']);?>
<a class="btn btn-default " href="posts/edit/">Edit</a>
<input type="submit" value="Delete" class="btn btn-danger">
</div>
Here are a few problems:
Your if-statement has a semicolon at the end, which essentially makes it a no-op.
You have two forms in your view, but only one </form> or form_close() call (and it's after the comment creation form). Essentially, it boils down to invalid HTML; pressing the Submit button will submit the first form (since it was never closed).
The below code addresses those problems:
<div class="post-body">
<hr>
<?php if ($this->session->userdata('user_id') == $posts['user_id']): ?>
<?= form_open('/posts/delete/' . $posts['id']) ?>
<a class="btn btn-default" href="/posts/edit/<?= $posts['id'] ?>">Edit</a>
<input type="submit" value="Delete" class="btn btn-danger">
<?= form_close() ?>
<?php endif ?>
</div>
