Hi I’m using some code to create a slideshow with lytebox functionality – the following code is used in the loop to pull each image attached to a post in sequence.
It seems to be only pulling the large image, even thought I’ve set the value to medium – any ideas how I can get .wp_get_attachment_url($attachment->ID, ‘medium’, false, false) to be pulling the medium sized images?
thanks
<?php
$argsThumb = array(
'order' => 'DESC',
'post_type' => 'attachment',
'post_parent' => $post->ID,
'post_mime_type' => 'image',
'post_status' => null
);
$attachments = get_posts($argsThumb);
if ($attachments) {
foreach ($attachments as $attachment) {
echo '<div class="images"><a class="lytebox" href="' .wp_get_attachment_url($attachment->ID, 'medium', false, false). '"><img src="'.wp_get_attachment_url($attachment->ID, 'medium', false, false).'" /><div class="caption">'.apply_filters('the_content', $attachment->post_content).'</div></a></div>';
}
}
wp_get_attachment_url()will only return url to original attachment file, this function only accepts attachment id as parameter.Use
wp_get_attachment_image_src()orwp_get_attachment_image()instead.echo out the following:
wp_get_attachment_image_src( $post->ID, 'medium')[0];to the attachment url for the medium sized image.Update for those finding this all these years later. The function you want is called
wp_get_attachment_image_url(). Documentation here.All you need to do is give it the attachment ID and the size and it will return either a string of the image url or false.
I don’t how above answer makes the answer.
wp_get_attachment_image_srcneed attachment id not post id.<?php echo esc_url((wp_get_attachment_image_src( get_post_thumbnail_id(get_the_id()), 'medium')[0])?>
