  • Order a foreach, by the value of a calculation of values in the array

    - by Mark
    I have an array as follows: $players = array( $player = array( 'name' => 'playername', 'speed' => '10', 'agility' => '10', 'influence' => '10' ) etc Then I calculate a $score, based on the sum of speed, agility and influence. $score = $p['speed'] + $p['agility'] + $p['influence']; How can I loop through my array, but order the results from highest to lowest $score?

  • Django: ordering numerical value with order_by

    - by h3
    I'm in a situation where I must output a quite large list of objects by a CharField used to store street addresses. My problem is, that obviously the data is ordered by ASCII codes since it's a Charfield, with the predictable results .. it sort the numbers like this; 1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 20, 21.... Now the obvious step would be to change the Charfield the proper field type (IntegerField let's say), however it cannot work since some address might have apartments .. like "128A". I really don't know how I can order this properly ..

I know the article says Depending on the compiler and settings but I just want to clear this.

  • class classname(value); & class classname=value; difference when constructor is explicit

    - by Mahesh
    When constructor is explicit, it isn't used for implicit conversions. In the given snippet, constructor is marked as explicit. Then why in case foo obj1(10.25); it is working and in foo obj2=10.25; it isn't working ? #include <iostream> class foo { int x; public: explicit foo( int x ):x(x) {} }; int main() { foo obj(10.25); // Not an error. Why ? foo obj2 = 10.25; // Error getchar(); return 0; } error: error C2440: 'initializing' : cannot convert from 'double' to 'foo'

  • initalizing two pointers to same value in "for" loop

    - by MCP
    I'm working with a linked list and am trying to initalize two pointers equal to the "first"/"head" pointer. I'm trying to do this cleanly in a "for" loop. The point of all this being so that I can run two pointers through the linked list, one right behind the other (so that I can modify as needed)... Something like: //listHead = main pointer to the linked list for (blockT *front, *back = listHead; front != NULL; front = front->next) //...// back = back->next; The idea being I can increment front early so that it's one ahead, doing the work, and not incrementing "back" until the bottom of the code block in case I need to backup in order to modify the linked list... Regardless as to the "why" of this, in addition to the above I've tried: for (blockT *front = *back = listHead; /.../ for (blockT *front = listHead, blockT *back = listHead; /.../ I would like to avoid pointer to a pointer. Do I just need to initialize these before the loop? As always, thanks!

  • question on find value in array

    - by davit-datuashvili
    i have seen a few days ago such problem there is given two array find elements which are common of these array one of the solution was sort big array and then use binary search algorithm and also there is another algorithm- brute-force algorithm for (int i=0;i<array1.length;i++){ for (int j=0;j<array2.length;j++){ if (array1[i]==array2[j]){ //code here } } it's complexity is O(array1.length*array2.length); and i am interested the first method's complexity is also same yes? because we should sort array first and then use search method binary search algorithm's complexity is log_2(n) so it means that total time will be array.length*log_2(n) and about sort? please explain me which is better

  • jQuery async ajax query and returning value problem (scope, closure)

    - by glebovgin
    Hi. Code not working because of async query and variable scope problem. I can't understand how to solve this. Change to $.ajax method with async:false - not an option. I know about closures, but how I can implement it here - don't know. I've seen all topics here about closures in js and jQuery async problems - but still nothing. Help, please. Here is the code: var map = null; var marker; var cluster = null; function refreshMap() { var markers = []; var markerImage = new google.maps.MarkerImage('/images/image-1_32_t.png', new google.maps.Size(32, 32)); $.get('/get_users.php',{},function(data){ if(data.status == 'error') return false; var users = data.users; // here users.length = 1 - this is ok; for(var i in users) { //here I have every values from users - ok var latLng = new google.maps.LatLng(users[i].lat, users[i].lng); var mark = new google.maps.Marker({ position: latLng, icon: markerImage }); markers.push(mark); alert(markers.length); // length 1 } },'json'); alert(markers.length); // length 0 //if I have alert() above - I get result cluster = new MarkerClusterer(map, markers, { maxZoom: null, gridSize: null }); } Thanks.

  • PHP login, getting wrong count value from query / fetch array

    - by Chris
    Hello, *EDIT*Thanks to the comments below it has been figured out that the problem lies with the md5, without everything works as it should. But how do i implent the md5 then? I am having some troubles with the following code below to login. The database and register system are already working. The problem lies that it does not find any result at all in the query. IF the count is 0 it should redirect the user to a secured page. But this only works if i write count = 0, but this should be 0 , only if the user name and password is found he should be directed to the secure (startpage) of the site after login. For example root (username) root (password) already exists but i cannot seem to properly login with it. <?php session_start(); if (!empty($_POST["send"])) { $username = ($_POST["username"]); $password = (md5($_POST["password"])); $count = 0; $con = mysql_connect("localhost" , "root", ""); mysql_select_db("testdb", $con); $result = mysql_query("SELECT name, password FROM user WHERE name = '".$username."' AND password = '".$password."' ") or die("Error select statement"); $count = mysql_num_rows($result); if($count > 0) // always goes the to else, only works with >=0 but then the data is not found in the database, hence incorrect { $row = mysql_fetch_array($result); $_SESSION["username"] = $row["name"]; header("Location: StartPage.php"); } else { echo "Wrong login data, please try again"; } mysql_close($con); } ?>

  • Passing trough a datagrid value

    - by Tonz
    I have a datagrid with 2 columns. One databound which display names and the other one is a hyperlink column. Column1 = databound column, Column2 = hyperlink column. column1: column2: --------------------- Name1 Modify Name2 Modify Next when i click on any of the values in Column2 i simply get redirected to a other page. This page contains 2 buttons/hyperlinks with Yes or No. (does not mather wich control, which one would bring the most easy to implement solution atm) When clicked on No it simply redirects back to the orignal page. Now the question is when i press "Yes" how exactly do i acces "Name1" (or Name2 if i press on the second modify)? Meaning if i press Yes i want to use this Name for certain opertions (xml). To put it short if i press on "modify" i want to be able to get that name associated with it (which is already displayed in the first bound column left of it). So the goal is to use that name in Xpath for example so i can make a query towards that node with that certain name. Hopefully this made some sence.
