Recently, I have had this request from a friend of mine, who had trouble with adding images into their post. In the following code, you will find “thickbox no_icon”, which is added for the plugin “auto-thickbox” used in that site. Enjoy!
/* Make all images inside the post links */
function make_all_images_links($content) {
// Make a list of images with a link
$list_with_links = array();
preg_match_all('#<a ([^>]*)><img ([^>]*)></a>#is', $content, $matches);
foreach ($matches[2] as $key=>$value) {
if (strstr($value, '/wp-content/uploads/'))
{
preg_match('#src="([^"]*)"#is', $value, $match);
$list_with_links[$match[1]] = $match[1];
}
}
// Get all the other images
preg_match_all('#<img ([^>]*)>#is', $content, $matches);
foreach ($matches[0] as $key=>$value) {
if (strstr($value, '/wp-content/uploads/'))
{
preg_match('#src="([^"]*)"#is', $value, $match);
$image = $match[1];
if ( !isset($list_with_links[$image]) )
{
preg_match('#-([0-9]*)x([0-9]*)#', $image, $parts);
if (isset($parts[0])) { $image = str_replace($parts[0], "", $image); }
$content = str_replace($value, '<a class="thickbox no_icon" href="'. $image .'">'.$value.'</a>', $content);
}
}
}
return $content;
}
add_filter( 'the_content', 'make_all_images_links', 99999 );
