wordpress - Show attached media image if no thumbnail image detected -

i'm using

 if ( has_post_thumbnail() ){} 

to check if post have thumbnail image,

 echo get_attached_media('image', $post->id); 

display word

 array 

i need show attached image

if trying 1 image in post , use thumbail, might want try one:

add you're functions.php :

// url of first image in post function catch_that_image() { global $post, $posts; $first_img = ''; ob_start(); ob_end_clean(); $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches); $first_img = $matches [1] [0];  // no image found display default image instead if(empty($first_img)){ $first_img = "/images/default.jpg"; } return $first_img; } 

to call put

<?php echo catch_that_image() ?>

in template file within loop.

i found brilliant code forum thread. saved me lot of times.
