postgresql supports using clauses in join statements, , want use simplify query. example: select * join b using (x, y, z) ... order x; how express laravel's query builder or eloquent? db::table('a') ->select('*') ->join('b', function($join)) ->where(...) ->orderby('x'); note question different https://stackoverflow.com/questions/31465918/how-to-generate-a-natural-join-query-with-laravels-query-builder asking natural join, not join using. also, i'm aware can have same effect multiple $join->on(...) statements, have duplicate columns , must quality columns in both a , b . is, i'd have write 'a.x' instead of 'x' though doesn't matter, because join query ensures both equal anyway. using clause solves problem neatly, generating single result column x , knowing there 1 value. so, answer - it's impossible. i continued question on laravel 5, , it's still imposs

(e.g. in php need add $this-> non-static method call) if that's correct make calls without this there way (any .jshintrc flag) turn off warning in jshint? no, , never correct in javascript. methods need called on receiver explicitly make this work , , need referred using property access notation because methods functions on properties in javascript. they&

i have old site uses xml path, reads , shows desired content. i used create new page, different xml-url. <?xml version="1.0" encoding="utf-8" ?> <items> <item> <link>http://www.url.to/image.html</link> <itemname>teapot</itemname> <city>munich</city> <countryid>de</countryid> <desc> <![cdata[here comes item description]]> </desc> <imageurl>http://www.url.to/image.jpg</imageurl> </item> </items> thats how items created. plain , simple. the php code generates site looks simple this: <?php //###################config start######################### $maxanzahl = 50; $zaehler = 4; //###################config end######################### $feed = simplexml_load_file('http://www.domain.tld/path-to-xml.php&filter1=rule1&filter2=rule2'); $items = $feed->items;

let's have 3 identical arrays, each looks this: [1,2,3,4] . by choosing value each array, want exhaust combinations, in example, desired result be: [1,2,3], [1,2,4], [1,3,4],[2,3,4] order doesnt matter. i'm iterating on every possibility, , that's waaaay slow. thought first doing check make sure iterator greater 1 left of it, in case of 1,4,... fail because 3rd array doesn't have bigger 4. additionally i'd need check make sure max of each column no greater column length - (# of repeating columns - column position . example column 2 not exceed 3. think i'm going down rabbit hole. any clever ways desired result in fewest iterations possible? modifying arrays fair game, too.

i'm attempting create 'popular products' bar @ bottom of page. here example: however, i've run problem multiple divs don't appear on same line. i've read different ways of doing including display:inline-block(everywhere says bad idea), display:table-cell(this creating new line still), , using spans display:inline-block(also still creating new line.) i've tried removing 'display' in .productbox class, doesn't show box @ all. here's code productbox: .productbox { width: 168px; height:135px; display:inline-block; background-color: #b2b2b2; } how using flex box ? here's html & css .wrapper { display: flex; } .wrapper div { width: 100px; height: 100px; background-color: blue; margin: 10px; } <div class="wrapper"> <div>div 1</div> <div>div 2</div> <div>div 3</div> <div>div 4</div> </div> note depe
