I had asked a question earlier, on getting post-thumbnails from another WP-site. There, the awesome Mike coded a SQL query whose results are then passes on to a PHP array. The piece of code from that answer that I want to modify is this.
$post_urls = $wpdb->get_col($sql); if (is_array($post_urls)) echo implode("\n",$post_urls);
Now the array holds values in the form of
<img src="/link/to/image.jpg"/>. Now how do I..
- Call the WP
image_resizefunction on each image URL?
- Apply my own CSS class to each image?
Thanks to Jan for the tips on optimizing the SQL query. Now the
$post_urls array will hold only plain URLs to the images. Can someone show me how to loop through each URL in the array and add prefixes (like
<img src=") and suffixes (like
" class="awesome-image"/>) to each of them?
