61 | Show Description for Header Images in Twenty Eleven

g+

This code is for a child theme of Twenty Eleven, because the direct editing of the default theme is not recommended.

Since wp3.4, the function get_custom_header() takes care of some of the information of the header images, such as width, height, and also the description or attachment id.

If added in header.php of the child theme, before:

<?php endif; // end check for removed header image ?>

the code below extracts the description information and outputs it below the header image:

<?php 
if ( function_exists( 'get_custom_header' ) && is_child_theme() ) :
if( get_custom_header()->description ) {
$header_description = get_custom_header()->description;
} elseif ( is_singular() && has_post_thumbnail( $post->ID ) && ( /* $src, $width, $height */ $header_img = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), array( $header_image_width, max($header_image_width,$header_image_height) ) ) ) && $header_img[1] >= $header_image_width ) {
$header_img_details = get_posts(array('p' => get_post_thumbnail_id( $post->ID ), 'post_type' => 'attachment'));
$header_description = $header_img_details[0]->post_content;
} elseif( $att_id = get_custom_header()->attachment_id ) { 
$header_img_details = get_posts(array('p' => $att_id, 'post_type' => 'attachment'));
$header_description = $header_img_details[0]->post_content;
} 
if( $header_description ) echo '<span class="header-description">' . $header_description . '</span>'; 
endif; 
?>
