  • Adding different objects to array, but only one object repeating

    - by Carpetfizz
    I have a small piece of PHP code that goes through valid values and fetches information about them. It then pushes it to an array. For some reason, I'm only getting the last item of $row, repeated several times. When I try to print_r at #1 in the code, the expected values are outputted. However, at the end of the loop, or outside of it, when I try to print_r($ipArray), I'm only getting the last value repeated multiple times. Any help would be much appreciated! while($row = mysqli_fetch_array($getIpQuery, MYSQLI_NUM)){ for($x=0;$x<count($row);$x++) { $getIpInfo = mysqli_query($dbcon, "SELECT * FROM ipInfo WHERE address='$row[$x]'"); $retrievedInfo = mysqli_fetch_array($getIpInfo, MYSQLI_NUM); $ipInfo->ipAddress = $retrievedInfo[0]; $ipInfo->portNum = $retrievedInfo[1]; print_r($ipInfo); //#1: Works perfectly fine. array_push($ipArray,$ipInfo); } } print_r($ipArray); //this is where I'm getting an output of only the last element of `$row`. Thanks! ~Carpetfizz

  • C++: How to require that one template type is derived from the other

    - by Will
    In a comparison operator: template<class R1, class R2> bool operator==(Manager<R1> m1, Manager<R2> m2) { return m1.internal_field == m2.internal_field; } Is there any way I could enforce that R1 and R2 must have a supertype or subtype relation? That is, I'd like to allow either R1 to be derived from R2, or R2 to be derived from R1, but disallow the comparison if R1 and R2 are unrelated types.

  • Pass two string to Detail View from Search Array

    - by waqqas
    I am using a tableview with a search function and is populated by a plist. I want to pass 2 strings through to a DetailView. But I can only get the sting used to populate the cell to pass over. I have tried many variations but can't figure it out. Any help would be greatly appreciated. DetailView *nextLevel = [DetailView alloc]; NSString *valueString; NSString *selectedTitle; if (arraySearch == nil) { NSString *key = [arrayDataKeys objectAtIndex:indexPath.section]; NSArray *nameSection = [dictAllData objectForKey:key]; NSDictionary *dict = [nameSection objectAtIndex:indexPath.row]; valueString = [dict objectForKey:@"name"]; selectedTitle = [dict objectForKey:@"word"]; } else { valueString = [arraySearch objectAtIndex:indexPath.row]; **selectedTitle = [arraySearch objectAtIndex:indexPath.row];** //Obviously this is wrong but this is the line I need help with } nextLevel.title = valueString; nextLevel.itemname = valueString; nextLevel.itemWord = selectedTitle;

  • How to connect two query results?

    - by nijansen
    I want to retrieve all ids within a certain timespan. The timestamps however, are stored in a different table: Table A has column my_id Table B has columns my_id, timestamp I would want something like SELECT id, time FROM (SELECT my_id AS id FROM A) q1, (SELECT timestamp AS time FROM B WHERE my_id = id) q2 ; But how can I get the value of id within a different subquery? Is there an elegant solution for this problem?

  • Getting changes in one column of an historical table

    - by Javi
    Hello, I have a table which stores historical data. It's mapped to an Entity with the following fields (I use JPA with Hibernate implementation): @Entity @Table(name="items_historical") public class ItemHistory{ private Integer id; private Date date; @Enumerated(EnumType.ORDINAL) private StatusEnum status @ManyToOne(optional=false) private User user; @ManyToOne(optional=false) private Item item; } public enum StatusEnum { OK, BAD,...//my status } In every row I store historical data of another table. I need to get the list of the changes on "status" column: the status, the date and the previous status on a specified item (It would be good as well getting the status and date when status was changed). I don't know if this is possible by using HQL. Thanks.

  • R: optimal way of computing the "product" of two vectors

    - by Musa
    Hi, Let's assume that I have a vector r <- rnorm(4) and a matrix W of dimension 20000*200 for example: W <- matrix(rnorm(20000*200),20000,200) I want to compute a new matrix M of dimension 5000*200 such that m11 <- r%*%W[1:4,1], m21 <- r%*%W[5:8,1], m12 <- r%*%W[1:4,2] etc. (i.e. grouping rows 4-by-4 and computing the product). What's the optimal (speed,memory) way of doing this? Thanks in advance.

  • How to convert from one co-ordinate system to another (graphics)

    - by Dororo
    I've been having issues with this for a little while now. I feel like I should know this but I can't for the life of me remember. How can I map the screen pixels to their respective 'graphical' x,y positions? The co-ordinate systems have been configured to start at the bottom left (0,0) and increase to the top-right. I want to be able to zoom, so I know that I need to configure the zoom distance into the answer. Screen |\ Some Quad | \--------|\Qx | \ Z | \ | \ \|Qy \ | Sx\ |Sy \| I want to know which pixels on my screen will have the quad on it. Obviously as Z decreases, the quad will occupy more of the screen, and as Z increases it will occupy less, but how exactly are these calculated? Thanks for any help.

  • which one is a faster/better sql practice?

    - by artsince
    Suppose I have a 2 column table (id, flag) and id is sequential. I expect this table to contain a lot of records. I want to periodically select the first row not flagged and update it. Some of the records on the way may have already been flagged, so I want to skip them. Does it make more sense if I store the last id I flagged and use it in my select statement, like select * from mytable where id > my_last_id order by id asc limit 1 or simply get the first unflagged row, like: select * from mytable where flagged = 'F' order by id asc limit 1 Thank you!

  • Create rails record from two ids

    - by Michael Luby
    The functionality I'm trying to build allows Users to Visit a Restaurant. I have Users, Locations, and Restaurants models. Locations have many Restaurants. I've created a Visits model with user_id and restaurant_id attributes, and a visits_controller with create and destroy methods. Thing is, I can't create an actual Visit record. Any thoughts on how I can accomplish this? Or am I going about it the wrong way. Here's the code: Model: class Visit < ActiveRecord::Base attr_accessible :restaurant_id, :user_id belongs_to :user belongs_to :restaurant end View: <% @restaurants.each do |restaurant| %> <%= link_to 'Visit', location_restaurant_visits_path(current_user.id, restaurant.id), method: :create %> <% @visit = Visit.find_by_user_id_and_restaurant_id(current_user.id, restaurant.id) %> <%= @visit != nil ? "true" : "false" %> <% end %> Controller: class VisitsController < ApplicationController before_filter :find_restaurant before_filter :find_user def create @visit = Visit.create(params[:user_id => @user.id, :restaurant_id => @restaurant.id]) respond_to do |format| if @visit.save format.html { redirect_to location_restaurants_path(@location), notice: 'Visit created.' } format.json { render json: @visit, status: :created, location: @visit } else format.html { render action: "new" } format.json { render json: @visit.errors, status: :unprocessable_entity } end end end def destroy @visit = Visit.find(params[:user_id => @user.id, :restaurant_id => @restaurant.id]) @restaurant.destroy respond_to do |format| format.html { redirect_to location_restaurants_path(@restaurant.location_id), notice: 'Unvisited.' } format.json { head :no_content } end end private def find_restaurant @restaurant = Restaurant.find(params[:restaurant_id]) end def find_user @user = current_user end end

    - by sciguy
    How do I remove the numbers on the x-axis only not the y-axis? Is it possible to shift the y-axis without shifting the functions? What I mean is, instead of having the y-axis at x = 0, could I have it at x = -5?
