Wordpress login form script

Question

I am looking for something very simple but I'm not quite sure how to achieve this. I have been researching for the past 2-3 hours and gathered a lot of useful information. However, my knowledge in both PHP and WordPress isn't enough to do this from scratch.

What I need is the following:

• When the user is not logged in, this HTML code should be displayed:

  <a href="#">Login</a>
  

• When the user is logged in, the previous HTML code should be replaced with:

  <span>Welcome, *username*</span>
  <a href="actual-link-for-logging-out-the-user">Logout</a>
  

Could anyone please help me out. I'd really appreciate the help :)

Thanks

You're going to want to use the is_user_logged_in() conditional tag to handle this.

global $current_user;
get_currentuserinfo();

if ( is_user_logged_in() ) {
  echo "<span>Welcome $current_user->user_login</span>".
       "<a href='".wp_logout_url()."'>Logout</a>";
} else {
  echo '<a href="#">Login</a>';
}

Other functions referenced: wp_logout_url() & get_currentuserinfo()

FYI, all of this could easily be found on Google or in the WordPress Codex.
