php - How to fetch all data from 2 tables and display all not working -


i'm trying fetch data items table , inventory table , display information. problem i'm having displayed right except displays whats in inventory table, , display items items table , quantity inventory table. how correctly here code

$result= mysqli_query($link, "select * items left outer join inventory on inventory.itemid=items.id inventory.userid = '".$userid."'");   while($row = mysqli_fetch_array($result) ) {        if ($row['type'] == 0 && $row['level'] > 0){         $item .= "          <td width='200px'>             <form action='gear.php' method='post'>                 <div class='featured_items'><img src='". $row['image']."' width='80' height='80' style='border: 1px solid #333'></div>                 <div class='featured_items_info'>". $row['itemname'] ." <br />                     att ". $row['attack'] ."                     | def ". $row['defense'] ."<br />                     cost ". $row['cost'] ."<br />                     own ". $row['quantity'] ."<br />                    <input type='hidden' name='gear_id' value='". $row['id'] ."' />                 <input type='submit' value='buy' />             </form>          </td>          ";      }    }

the left join didn't work way intended because used user_id field, belonged inventory. moving condition on fix it:

select id, type, level, image, itemname, attack, defense,      cost, coalesce(inventory.quantity, 0) quantity items  left outer join inventory on inventory.itemid=items.id , inventory.userid = '".$userid."'"

just make sure use coalesce in select handle items user doesn't have.

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; } &l
