c# - Possible to automatically add elements to collection? -

-
i new @ entity framework (and stack overflow - first question!): right got following entities in db: blog: [key] [databasegeneratedattribute(databasegeneratedoption.identity)] public int id { get; set; } public virtual ilist<post> posts { get; set; } post: [key] [databasegeneratedattribute(databasegeneratedoption.identity)] public int id { get; set; } public int blogid { get; set; } [required] [foreignkey("blogid")] public virtual blog blog { get; set; } currently whenever add post manually add collection of corresponding blog. wonder if it's possible automatically add them collection add posts referencing corresponding blog? you use entity class create entity rather new , ie: posts.add(post.create()); instead of posts.add(new blog()); but if must pass arguments, need do post p = post.create(); p.blogid = 1234; p.somestring = "test"; p.somedate = datetme.now; posts.add(p); and always, call db.savechanges();

PHP array_filter with get_class filter -

-
i have array of objects, , want check if classname in it. tried: $all_classnames = array_filter($obj_array, 'get_class'); $found = in_array("classname_to_test", $all_classnames); only, $all_classnames still holds original object array instead of array of classnames (through get_class). missing here? you want use array_map (which transforms input array based on callback function) instead of array_filter : $all_classnames = array_map('get_class', $obj_array); note array_map takes arguments in reverse order other array functions use callback because php.
