Question

我的表是：

barangtbl：id，judul_barang，judul_seo，keywords，deskripsi，id_kat，id_sub，id_supersub，kategori_seo，view，gambar
kategori：id_kat，nama_kat
subkategori：id_sub，id_kat，nama_sub
supersubkategori：id_supersub，id_sub，id_kat，nama_supersub

我在使用PHP从数据库中显示类别数据时出现问题，问题是当我点击链接：localhost / test / category.php？name = HPI时，它没有显示任何数据，但如果我将HPI更改为数字：15，它显示全部。

15是在supersubkategori表上的id_supersub数据，我用barangtbl表加入。所以，我想要的只是有人点击：localhost / test / category.php？name = HPI它将显示内部有HPI类别的数据。怎么解决这个问题？

<?php
if (isset($_GET['name']))
{
    $kategori = $_GET['name']; 
}

include "config.php";

if ((isset($kategori)) =='')
{
$query = "SELECT * FROM barangtbl INNER JOIN supersubkategori on supersubkategori.id_supersub = barangtbl.id_supersub ORDER BY id DESC LIMIT 0,12";
$hasil = mysql_query($query);
$numrows = mysql_num_rows($hasil);
}
else
{
    echo "
                <table width=\"100%\">
                    <tr>
                        <td align=\"center\"><b><font color=\"red\" size=\"2.5\">[ ".$_GET['name']." ]</b></font></td>
                    </tr>
                </table>";

    $query = "SELECT * FROM barangtbl WHERE id_supersub = '$kategori' ORDER BY id";
    $hasil = mysql_query($query);
    $numrows = mysql_num_rows($hasil);
}
?>

<table cellpadding="10" cellspacing="2" align="center">
    <tr>
    <?php
        $kolom=3;
        $x = 0;
        if($numrows > 0)
        {
            while($data=mysql_fetch_array($hasil))
            {
                if ($x >= $kolom) 
                {
                    echo "</tr><tr>";
                    $x = 0;
                }
        $x++;
    ?>
        <th>             
            <div id="title">
                <a href="product.php?id=<?php echo $data['id']; ?>">
                <?php echo $data['judul_barang']; ?>
                </a>
            <br><br>
          </div>

          <div id="image">
            <a href="product.php?id=<?php echo $data['id']; ?>">
                <img width='150' height='150' valign='top' border='1,5' src="product/<?php echo $data['gambar']; ?>" />
            </a>
            <br><br>
            </div>       

        <div id="action">
        <?php 
            echo '
                    <a href="product.php?id='.$data['id'].'">
                        <img src="images/detail.jpg"\ title="Detail Barang" border="0" width=\"50\" height=\"30\">
                    </a>';
                ?>
            </div>
          <hr />    
        </th>
    <?php
        }
        }
    ?>
    </tr>
</table>
