compare.html

  THIS:

  <form method="post" action="" accept-charset="UTF-8">
    <input type="hidden" name="action" value="entries/saveEntry">
    <input type="hidden" name="redirect" value="blog/{{ entry.slug }}">
    <input type="hidden" name="GUID" value="{{ entry.guid }}">

    <label for="title">Title</label>
    <input id="title" type="text" name="title" value="{{ entry.title }}">

    <label for="body">Body</label>
    <textarea id="body" name="fields[body]">{{ entry.body }}</textarea>
    
    <input type="submit" value="Publish">
  </form>

  VS:

  <form method="post" action="" accept-charset="UTF-8">
    <input type="hidden" name="action" value="entries/saveEntry">
    <input type="hidden" name="redirect" value="blog/{{ entry.slug }}">
    <input type="hidden" name="entryId" value="{{ entry.id }}">
    <input type="hidden" name="sectionId" value="1">
    <input type="hidden" name="slug" value="{{ entry.slug }}">
    <input type="hidden" name="enabled" value="1">

    <label for="title">Title</label>
    <input id="title" type="text" name="title" value="{{ entry.title }}">

    <label for="body">Body</label>
    <textarea id="body" name="fields[body]">{{ entry.body }}</textarea>

    <label for="keywords">Keywords</label>
    <input id="keywords" type="text" name="fields[keywords]" value="{{ entry.keywords }}">
    
    <input type="submit" value="Publish">
  </form>
