mysql - My php loop is looping 11 times, instead of one. Cant find the bug -


here php code. functions require, query , render given us.

<?php  // configuration require("../includes/config.php");   $rows = cs50::query("select `symbol`, `shares`, `cash` `portfolios`, `users` ?", $_session["id"]);  $positions = []; foreach ($rows $row) {     $stock = lookup($row["symbol"]);     $total = ($stock["price"] * $row["shares"]);      if ($stock !== false)     {         $positions[] = [             "name" => $stock["name"],             "price" => $stock["price"],             "shares" => $row["shares"],             "symbol" => $row["symbol"],             "total" => $total,             "cash" => $row["cash"]         ];     } }  // render portfolio render("portfolio.php", ["positions" => $positions, "title" => "portfolio"]);

here html output

<div id="middle"> <table class="table table-striped">  <thead>     <tr>         <th >symbol</th>         <th >name</th>         <th >shares</th>         <th >price</th>         <th >total</th>     </tr> </thead> <tbody>      <?php foreach ($positions $position): ?>         <tr>             <td align="left" ><?= $position["symbol"] ?></td>             <td align="left" ><?= $position["name"] ?></td>             <td align="left" ><?= $position["shares"] ?></td>             <td align="left" ><?= number_format($position["price"], 2) ?></td>             <td align="left" ><?= number_format($position["total"], 2) ?></td>         </tr>     <?php endforeach ?>  <tr>     <td colspan="4" align="left">cash</td>     <td align="left"><?= number_format($position["cash"], 2) ?></td> </tr>  </tbody>  </table>

my guess there wrong foreach loop. im not quite sure, there faults in sql database.

my mysql database consist of 3 rows user_id, symbol, shares. , user_id have 3 diffrent stocks 10 shares each.

anyone know wrong?

if runs 7 times means there 7 rows returned, foreach loop fine. issue here:

 $rows = cs50::query("select `symbol`, `shares`, `cash` `portfolios`, `users` ?", $_session["id"]);

you aren't indicating column should equal id, it's returning of them likely. need this:

$rows = cs50::query("select `symbol`, `shares`, `cash` `portfolios`, `users` portfolios.user_id = ?", $_session["id"]);

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
