MySQL subselect in query -


i following results query:

id_product_attribute | id_product | reference | name         | total 12                   | 1          | 234235    | product_name | 2 14                   | 2          | 235435    | product_name | 7 16                   | 3          | 235325    | product_name | 4

etc

but when use query: 

select pa.id_product_attribute, p.id_product, pa.reference, cl.name, sum(od.product_quantity) total ps_product_attribute pa left join ps_order_detail od on od.product_attribute_id = pa.id_product_attribute left join ps_product p on pa.id_product = p.id_product left join ps_category_product cp on cp.id_product = p.id_product left join ps_category_lang cl on cp.id_category = cl.id_category cp.id_category = 141 , cl.id_lang = 6;

it gives me results:

id_product_attribute | id_product | reference | name         | total 12                   | 1          | 234235    | product_name | 13

so in 'total' column shows me total of all, instead of seperate per row.

can tell me i'm doing wrong in query?

your source data help, @ least forgot group by @ end. current query, should add;

group pa.id_product_attribute, p.id_product, pa.reference, cl.name

with mysql, can choose group by less columns , random selection of values in other ones, if possible, should group by columns don't have aggregates (like sum in case) on them.

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...
