[quote author="Michael Wales" date="1242415829"]I prefer example.com/this-is-my-title or example.com/category/this-is-my-title for SEO purposes.

Code:

// Catch example.com/category/this-is-my-title
$route['([a-zA-Z0-9-]+)/([a-zA-Z0-9-]+)'] = 'blog/post/$1';
// Catch example.com/category
$route['([a-zA-Z0-9-]+)'] = 'blog/category/$1';

Code:

<?php echo anchor(url_title($category, 'dash', TRUE) . '/' . url_title($title, 'dash', TRUE), $title);

Code:

function post($title_slug = NULL) {
  if ($title_slug === NULL) {
    // If the user somehow got here w/o having a slug
    // send them to the homepage
    redirect();
  }

  // Load the post from database using the unique slug
  // If num_rows() === 0, throw a 404
  // Else, Display view
}
