is possible submit hidden name value pair based on button clicked? here's form: <form action="post" action=""> <button> <input type="hidden" name="vote" value="up"/> vote up! </button> <button> <input type="hidden" name="vote" value="down"/> vote down </button> </form> for reason, name value pair received latter (the first 1 got replaced). example user clicked on 'vote down', still $input['vote'] = up does know how fix this? this because put both of them in form parameters received server like vote=up&vote=down assume access using php associative array received latest value in entries having same key. aside, why not just <form action="post" action=""> <button> <input type="hidden" name="vote" value=&quo

i find myself in situation facing multiple compilation/linker errors in c++ project due bad design decisions (made else :) ) lead circular dependencies between c++ classes in different header files (can happen in same file) . fortunately(?) doesn't happen enough me remember solution problem next time happens again. so purposes of easy recall in future going post representative problem , solution along it. better solutions of-course welcome. a.h class b; class { int _val; b *_b; public: a(int val) :_val(val) { } void setb(b *b) { _b = b; _b->print(); // compiler error: c2027: use of undefined type 'b' } void print() { cout<<"type:a val="<<_val<<endl; } }; b.h #include "a.h" class b { double _val; a* _a; public: b(double val) :_val(val) { } void seta(a *a) { _a = a; _a->print();

i have places , locations tables. place have many locations. location belongs place. place: id title location: id place_id floor lat lon class location extends model { public function place() { return $this->belongsto('app\place'); } } and class place extends model { public function locations() { return $this->hasmany('app\location'); } } and need find places, belongs 1st floor. select * places inner join locations on places.id = locations.place_id locations.floor = 1 how should done in eloquent? is similar place::where('locations.floor', '=', 1)->get() exists? yes, know there wherehas : place::wherehas('locations', function($q) { $q->where('floor', '=', 1); })->get() but generates bit complex query counts: select * `places` (select count(*) `locations` `locations`.`place_id` = `places`.`id` , `floor` = '1') >= 1

i new r , save out puts after loop (i in 1:5) { (d in 1:10) { fonction1 fonction2 fonction3 } } at end have 1 list-> contains 5 list-> contains 1*10 data frame -> contains number*3 numeric data. (i dont know if im saying correctly, want have is: in matlab, there 1*5 structure -> contains 5 1*10 structure -> contain number*3 numeric data). thanks in advance looks looking after following: out <- list() (i in 1:5) { outlist <- list() (d in 1:10) { outvect <- c() outvect[1] <- fonction1() outvect[2] <- fonction2() outvect[3] <- fonction3() outlist[[d]] <- outvect } out[[i]] <- outlist } then can at: str(out) to see structure of answer

i made commit on local copy of master , added commit separate branch / pull request. i'm on local master, start here: git:(master) git status on branch master branch ahead of 'origin/master' 1 commit. (use "git push" publish local commits) nothing commit, working directory clean i want out of commit, since merge branch, i: git: (master) git pull origin master https://github.com/basho-labs/the-riak-community * branch master -> fetch_head up-to-date. and i'm still in same state. out of this, i: git:(master) git checkout head~1 note: checking out 'head~1'. in 'detached head' state. can around, make experimental changes , commit them, , can discard commits make in state without impacting branches performing checkout. if want create new branch retain commits create, may (now or later) using -b checkout command again. example: git checkout -b new_branch_name head @ abd0327... but what's cleanest way ha

i looking check variabe type based on value held in variable struggling it. i'm new ruby can tell me how have value of variable interpreted in expression? current code looks like:- if variable.is_a?("#{variable_type}") puts variable end where variable contain , variable_type contains type of variable string or fixnum. code gives me typeerror: class or module required. thoughts? your code sends string object #is_a? method , #is_a method expects class. for example, string vs. "string" : variable = "hello!" variable_type = string "#{variable_type}" # => "string" # code: if variable.is_a?("#{variable_type}") puts variable end #is_a? expects actual class (string, fixnum, etc') - can see in the documentation #is_a? . you can adjust code in 2 ways: pass class, without string. convert string class using module.const_get . here example: variable = "hello!" variable_

is bad idea define #define type(x) typename decltype(x) as fast way member type of class of variable in c++11? justification: consider following (oversimplified) example: #include <iostream> #define type(x) typename decltype(x) class { public: typedef int mtype; void set(mtype const& x) { foo = x; } mtype get() { return foo; } private: mtype foo; }; make() { return a(); } int main() { auto = make(); type(a)::mtype b = 3; a.set(b); std::cout << a.get() << "\n"; return 0; } that is, have class member type "mtype" , function returns me instance of class. auto, don’t have worry name of class long know function job. however, @ 1 point or another, have define variable of specific type, which, convenience, has typedef "mtype" in class. if have variable name "a" around know variable has class, can do typename decltype(a)::mtype b; to define variable b of type a::mtype. is bad idea put &qu
