$stmt = $db->prepare("UPDATE cjv_blog SET blog_title :title, blog_description = :description, blog_content = :content, blog_category = :category WHERE blog_id = :id");

替换为:

$stmt = $db->prepare("UPDATE cjv_blog SET blog_title = :title, blog_description = :description, blog_content = :content, blog_category = :category WHERE blog_id = :id");
