Get the first image from the wordpress post and display it
February 25, 2009 · Print This Article
Most WordPress users are using custom fields to display thumbs on their blog homepage.
It is a good idea, but do you know that with a simple php function, you can grab the first image from the post, and display it.
You can simply call the function within the loop to display the first image from the post:
<?php echo get_first_image() ?>
But first, paste this function follow on your functions.php file.
function get_first_image() {
global $post, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i’, $post->post_content, $matches);
$first_img = $matches [1] [0];
if(empty($first_img)){ //Defines a default image
$first_img = “/images/default.jpg”;
}
return $first_img;
}

Would you know how I could use this code to display images with my recent posts as well as with related posts.
