Question

I can’t get all the sub-menu items to show on the “New Motorcycles” section on http://www.mattmaclennan.co.uk/a2. For example, Adventure should have three options coming off, not one. Here is the code I have used.

<?
$output = mysqli_query("SELECT * FROM bikes, bikeTypes WHERE bikes.model_id = bikeTypes.model_id GROUP BY bikeTypes.model_id");
while($row = mysqli_fetch_array($output))
 {
   echo "<li><a href='test.php?id=" . $row['model_id'] . "'>".$row['model'].'</a><ul>';
   echo "<li><a href='details.php?id=" . $row['bike_id'] . "'>" . $row['bikeName'] . "</a></li>";
   echo '</ul>';   
   echo '</li>';
 }
//var_dump($result);
?>

Any ideas guys? Thanks!

EDIT: Here is the structure of both tables from phpMyAdmin:

bikeTypes table:
bike types table http://www.mattmaclennan.co.uk/a2/images/bikeTypesTable.jpg

bikes table:
bikes table http://www.mattmaclennan.co.uk/a2/images/bikesTable.jpg

Answer 1

Try this:

SELECT bikeTypes.id,bikeTypes.name,bikes.name,bikes.id FROM bikeTypes LEFT JOIN bikes ON
bikes.model_id = bikeTypes.model_id

If you see that the query I have written has a LEFT JOIN in it.What are you doing is treated as an INNER JOIN by the DB engine.

But the thing you need here is

 $output = mysqli_query("SELECT * FROM bikeTypes");
    while($row = mysqli_fetch_array($output))
     {

       echo "<li><a href='test.php?id=" . $row['model_id'] . "'>".$row['model'].'</a><ul>';
       $subcat = mysqli_query("SELECT * FROM bikes WHERE model_id = $row['model_id']");

       while($rowSub = mysqli_fetch_array($subcat)){    
       echo "<li><a href='details.php?id=" . $rowSub['bike_id'] . "'>" . $rowSub['bikeName'] . "</a></li>";
       }
       echo '</ul>';   
       echo '</li>';

 }

Just see where you want to close ul and li.
