i have been making login/register system , 1 problem have run not allowing duplicate email addresses being registered. want work database wont accept data duplicate email , user alerted too. sort of new php unsure of how this. thanks. my php if (empty($_post['email'])) { $error[] = 'please enter email '; } else { if (preg_match("/^([a-za-z0-9])+([a-za-z0-9\._-])*@([a-za-z0-9_-])+([a-za-z0-9\._- ]+)+$/", $_post['email'])) { //regular expression email validation $email = $_post['email']; } else { $error[] = 'your email address invalid '; } } if (empty($_post['password'])) { $error[] = 'please enter password '; } else { $password = $_post['password']; } if (empty($error)) //send database if there's no error ' { // if everything's ok... // make sure email address available: $query_verify_email = "select * members email ='

i've tried replace while loop stream when use stream version, last element missing. think understand why it's missing can't figure how fix this. suggesting? there better way this? thanks using stream: if(cursor.movetofirst) { val result = stream.continually(( song( cursor.getlong(c(basecolumns._id)), cursor.getstring(c(mediacolumns.title)) ), cursor.movetonext)) .takewhile(_._2) .map(_._1) result.tolist } here while loop version works fine. cursor.movetofirst() var = 0 var list: list[song] = list.empty while (i < cursor.getcount()) { val s = song( cursor.getlong(c(basecolumns._id)), cursor.getstring(c(mediacolumns.title))) = + 1 list = list :+ s cursor.movetonext() note: movetonext move cursor next row. method return false if cursor past last entry in result set. suppose have 1 entry. produce tuple (song, false) and throw away. that's no good. want keep song though there's not another song ther

http://docs.phonegap.com/en/2.8.0/cordova_storage_storage.md.html#storage this link official guide. very confused. first half of page describes storage method , seemingly lower down on page local storage method described. are these 2 things distinctly different. know there size limit of 5mb local storage implementation, there similar size limit on sqlite storage method. or wrong , these 2 things describing 2 sides of same coin? any clarification appreciated. the local storage key value paired methodology storing data sqlite storage uses actual database structure store complex data. however there 1 more option jstorage.

compare 2 maps ( std::map<std::string, std::unsigned int> ) value , identify distinct elements. typedef std::map<std::string /* file name*/, unsigned int /*crc*/> mmap; list of files each file in list calculated crc. file name not changed, crc changet. if have 2 maps, distinct entries, named oldmap , newmap , can use std::set_difference unique entries both maps. see following example of how can done. #include <map> #include <string> #include <algorithm> #include <utility> #include <iterator> #include <iostream> int main() { // 2 maps containing values. std::map<std::string, int> oldmap { {"test1", 1}, {"test2", 2}, {"test3", 3} }; std::map<std::string, int> newmap { {"test2", 2} }; // create new map holds distinct pairs. std::map<std::string, int> diffmap; // add distinct pairs diffmap. std::set_difference(begin(oldmap), end(oldma

i have button used part of navigation bar. what need when user hovers on button, buttons text becomes hidden, , 3 different links appear inside button. the initial button shouldn't have link attached it, 3 options appear after hovered over. hopefully makes sense; here fiddle might make clearer. <ul class="ulmenu"> <li><a href=# class="a">test</a></li> </ul> at simplest, i'd suggest following: <ul id="nav"> <li>navigation</li> <li><a href="#opt1">option 1</a></li> <li><a href="#opt2">option 2</a></li> <li><a href="#opt3">option 3</a></li> </ul> with following css: /* default display 'li' elements: */ #nav li { display: inline-block; } /* hides 'li' elements follow 'li' element, hides 'li:first-child' w

i have centos6 installed image in vmware, lets call dev environment. host pc running windows 7. i've been developing websites setup quite time now. my problem begins when started working on themes mobile devices. sure can use chrome or firefox's developer tools over-ride user-agents , test layout in regular browser. test in android phone, i'll have commit changes , deploy site(to staging), time-consuming. i able able test work in android phone while it's still in dev environment. imagine quite possible, don't know how. so, here issues: how access vmware images on wifi? have laptop , can't access domain registered in dev environment on wifi? there setting this? or should able access have problem in laptops wifi?(which do, btw) if i'm correct, there should 'hosts' file in linux edit redirect domain? how find this? need root phone? if i'm not correct, how should able this? i able access dev environment on ssh in android device. i'

got complicated problem little information on it. ok have site people upload files onto, files base 64 encoded , sent site. second site saves file , adds database record file. somewhere in process, 1 in 8 files losing content. this system has been 5 months, error has appeared in last month, co-inciding server move. there nothing in common files e.g. extension or source, nothing significant time, , no php errors being logged. have got copies of files failed, , when try upload them, work fine. the first site wont let through blank file, has happening in second site, believe maybe have missed php config option thats causing this. thoroughness sake here code saving file: $filename = time() . ($id->count + 1) . '-' . $this->post['jobid'] . $this->post['filetype']; file_put_contents(dir_tmp . "cvs" . ds . $filename, base64_decode($this->post['cv']), file_append); the server in question linux centos 6 64 bit. so sum up, probl

my real question is, 'why doesn't backtracking speed search?' i'm not sure if makes sense without more context... this question academic - code 'works' , program finds solutions i'm expecting....but want make sure understand terminology. illustrate things, let's use specific example we'd need search algorithm - n-queens problem. n-queens problem - placing n queens on n×n chessboard in such way no queen can attack another. one solution there lots of example code on internet can found searching for, 'n-queens backtracking', , wikipedia's article on backtracking uses n-queens in explanation of backtracking ( http://en.wikipedia.org/wiki/backtracking ). idea, understand it, given board configuration invalid - let's 2 places queens can attack each other, algorithm disregards board configurations made adding additional pieces. i've implemented (non-recursive/non-backtracking) depth-first , breadth-first version
