Automatically Get Images on Post Content
Nov 20th
The problem. Using custom fields to display images associated with your post is definitely a great idea, but many WordPress users would like a solution for retrieving images embedded in the post’s content itself.
The solution. As far as we know, there’s no plug-in to do that. Happily, the following loop will do the job: it searches for images in post content and displays them on the screen.
<?php if (have_posts()) : ?> <?php while (have_posts()) : the_post(); ?> <?php $szPostContent = $post->post_content; $szSearchPattern = '~<img [^\>]*\ />~'; // Run preg_match_all to grab all the images and save the results in $aPics preg_match_all( $szSearchPattern, $szPostContent, $aPics ); // Check to see if we have at least 1 image $iNumberOfPics = count($aPics[0]); if ( $iNumberOfPics > 0 ) { // Now here you would do whatever you need to do with the images // For this example the images are just displayed for ( $i=0; $i < $iNumberOfPics ; $i++ ) { echo $aPics[0][$i]; }; }; endwhile; endif; ?>
