SQL语句似乎正常工作，但未显示在网站php SQL上

Question

hello im doing a website that sells games as a project and one of my problems is that i cant seem to display a value from the database on phpmyadmin onto the webpage, no errors are flagging up when i go on the page i want the value to be displayed so im presuming its working to some degree.

I have also entered the query into phpmyadmin to test it to see if there are any errors, but it displayed none and did the SELECT query just fine and outputted the desired result.

Here is my query statement at the top of the page

$query = "SELECT rectable.gameID, rectable.gameIMG, rectable.gamePrice, rectable.gameName, members.country, basket.quantity FROM rectable INNER JOIN basket 
ON rectable.gameID=basket.gameID INNER JOIN members ON basket.id=members.id

It outputs the following

basically im trying to get the Country from the database and display it.

My code within php is this

<?php
$count = 0;
while ($count < $numrow)
{
$row = $results -> fetch_assoc();
extract($row);
echo"<div>";
echo"<div id='recommended_games2'>";
echo "<img src='images/".$gameIMG."' />";
echo "</div>";


echo '<div id="price_tag2">';
echo '<div class="price_tag" name="price" method="POST">£'.$gamePrice. '</div>';
echo'</div>';

echo '<div id="quantity_tag">';
echo '<div id="quantity_tag" >Quantity  '.$quantity.'</div>';
echo'</div>';

echo"<img class='box1' src='Images/Grey-Banners.png' />";
echo"</div>";
$count = $count + 1;  


}     
echo '<div id="delete_all">';
echo '<form action="cart.php">';
echo '<input id="hide_button" type="submit" value="Edit Cart"  />';
echo '</form>';
echo '</div>';

echo '<div id="totalprice">';
echo '<form action="" method="POST">';
echo '<input type="submit" value="Order Items"  />';
echo '</form>';
echo '</div>';

echo '<div id="address" >'.$country.'</div>';


?>

It displays the website something like this

But as you can see i cant get the country to be displayed.

try to change your loop like the following:

while ($row = $results -> fetch_assoc()) {
    echo"<div>";
    echo"<div id='recommended_games2'>";
    echo "<img src='images/".$row['gameIMG']."' />";
    echo "</div>";


    echo '<div id="price_tag2">';
    echo '<div class="price_tag" name="price" method="POST">£'.$row['gamePrice']. '</div>';
    echo'</div>';

    echo '<div id="quantity_tag">';
    echo '<div id="quantity_tag" >Quantity  '.$row['quantity'].'</div>';
    echo'</div>';

    echo"<img class='box1' src='Images/Grey-Banners.png' />";
    echo"</div>";
    echo '<div id="address" >'.$row['country'].'</div>';
}

I'm not sure here, but you have "INNER JOIN members ON basket. id =members.id" in your code while you joined basket on rectable with gameID. Do you have two different ID columns in your "basket" table?

Thank you all for you help but i have realised the problem which i think brian driscoll sort of answered, Basically it was basically working but the reason for it not displaying is because in my database i only entered the address for one of the users and for it to be displayed you had to be logged on as that user, since i have set up session variables and ids which meant each cart was specific to the user. Which meant only the country that was associated with the user was displayed.

Thanks for the help guys
