title: MySQL Table for comments
body: <p>I made a link to a page in a document named "find.php" and made <code>$id</code> equal to the id of an article. When you click on it, the url looks like <code>find.php?id=w/e</code>. I want to be able to post comments on the page. For instance if I wanted to post a comment on <code>find.php?id=40</code>, how would I display the comments? By the way, there's a  table for the articles and a table for the comments. </p>
  
  <p>For reference, I set up my comments table as</p>
  
  <pre><code>com_id int (11)
  title text
  user varchar (255)
  msg text
  </code></pre>
  
  <p>Would I need a foreign key also?</p>
