一、发布文章的时候,设置特色图像:
二、代码自动截取文章特色图像:
在主题根目录下,找到functions.php文件,并复制下面代码:
function autoset_featured() {
global $post;
$already_has_thumb = has_post_thumbnail($post->ID);
if (!$already_has_thumb) {
$attached_image
= get_children(
“post_parent=$post->ID&post_type=attachment&post_mime_type=image&numberposts=1″
);
if ($attached_image) {
foreach ($attached_image as $attachment_id => $attachment) {
set_post_thumbnail($post->ID, $attachment_id);
}
}
}
} //end function
add_action(‘the_post’, ‘autoset_featured’);
add_action(‘save_post’, ‘autoset_featured’);
add_action(‘draft_to_publish’, ‘autoset_featured’);
add_action(‘new_to_publish’, ‘autoset_featured’);
add_action(‘pending_to_publish’, ‘autoset_featured’);
add_action(‘future_to_publish’, ‘autoset_featured’);
