WordPress Custom Fields and Checking for Values

I have been building sites with WordPress for about a year now and I love it. I love the versatility that WordPress offers and I have had great success with Search Engine Visibility. I just recently read a great article on how to use custom fields to take your wordpress site to the next level.

I setup a few pages on my site StamfordCTGuide, which one section in particular, hotels. I added a few hotels and ran into some issues of missing images. Instead of adding the missing images image to each custom field entry in Admin. I wrote a little php if statement to check to see if there is a value present, and if there isnt - to show a default "no image available".

Here is the php that I wrote, its simple - but really my first experience with writing php. I have been doing ActionScript 3 for about 6 months, and the basic principles are the same.

PHP:
  1. <a href="<?php the_permalink() ?>" rel="bookmark"><img src="<?php
  2.             if ($hotels_img != null) {
  3.             echo $hotels_img[0];
  4.             }
  5.             else if ($hotels_img == null) {
  6.             echo "http://www.stamfordctguide.com/wp-content/themes/stamfordctguide/images/noimage.gif";
  7.             }
  8.            
  9.             ?>" border="0" width="50"></a>
