more tag with gallery images
I’m still a bit new to WordPress, and to php, so this might be really simple, but here goes:
I’m trying to make my default index.php page display an image from a gallery, instead of a “Read More…” link in place of the <!–more–> tag. I want it to look at each post (all posts contain a gallery) and pick the first image from the post to use. Here is the code I’m using, inside The Loop,
$gallery=get_post_gallery_images( the_ID() );
$image_attributes = wp_get_attachment_image_src( $gallery );
the_content(‘<img src=”‘.$image_attributes.'” width=”300″ height=”211″ />’);
From what I read about get_post_gallery_images it should return an array of the images in the gallery found on the page which is referenced by the_ID(). I’m trying to get the url of the first image in the gallery, and from what I understand about wp_get_attachment_image_src, it should give me the url from the image id.
When I use this code it displays an image, so I know it can be done if I can get the URL:
<?php the_content('<img class="alignleft size-medium " alt="Memories Portfolio" src="http://www.caitlinsabo.com/wp-content/uploads/2013/10/home-page-1-300x211.jpg" width="300" height="211" />'); ?>
