terminology - Looking for a general name or term for this particular database table design -


i've run particular sql table design , i'm trying see if there's common name people use describe it. table has definition this:

create table [attributes] (   [id] [int] not null,   [field_1] [varchar](30) null,   [value_1] [varchar](30) null,   [field_2] [varchar](30) null,   [value_2] [varchar](30) null,   [field_3] [varchar](30) null,   [value_3] [varchar](30) null,   [field_4] [varchar](30) null,   [value_4] [varchar](30) null,   [field_5] [varchar](30) null,   [value_5] [varchar](30) null,   [field_6] [varchar](30) null,   [value_6] [varchar](30) null,   [field_7] [varchar](30) null,   [value_7] [varchar](30) null,   [field_8] [varchar](30) null,   [value_8] [varchar](30) null,   [field_9] [varchar](30) null,   [value_9] [varchar](30) null,   [field_10] [varchar](30) null,   [value_10] [varchar](30) null )

the idea allow variable number of attributes defined (up max of 10 in case), without using more normalized design.

i'm not looking pros/cons of approach, know of common name or term used describe type of database table design?

i call (particularly nasty) form of key-value store.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
