Hi all freaks!! :P

I'm working on a Local Commerce WebGIS application for a final master thesis and i'm having troubles with the dynamic links. I have the following database structure:

Comercial categories
ID_CAT
Categorie

Comercial Sub-Categories
ID_CAT
ID_SUB_CAT
Sub_Categorie

(and then the comercial stores table wich dont matter for this case)

When i try to make dynamic link with the ID_CAT to the Sub_Categorie matching the same ID_CAT i get the following error:

Parse error: parse error, unexpected T_STRING, expecting ']' in C:\ServidorGis\web\Database\subcategorias.php on line 14

the code for the subcategories.php is:
(line 14 is in bold)

can anyone please tell me what am i doing wrong??
Thanks in advance!

O I might see your problem!

if (isset($_GET['<?php echo $row_Categorias['ID_Cat']; ?>
']))

I think your single quotes are confusing it... also try taking out the <?php echo... reading through your code it is unneeded. The ; or the ?> could be confusing it considering you have so many of the <?php open
if (isset($_GET["$row_Categorias['ID_Cat']"]))

Hi all!

Thank you very much noobie! It worked!! :D
The problem was that, as you know (i didn't), dreamweaver don't delete unnecessary code generated after arranging and re-arranging url parameters for the dinamic links!! So...i've tryed to rebuild my sub_cat php page and it worked!!

the new code is:

<?php require_once('../Connections/MySQL_connection.php'); ?>
<?php
$colname_Subcategorias = "1";
if (isset($_GET['categoria_link'])) {
$colname_Subcategorias = (get_magic_quotes_gpc()) ? $_GET['categoria_link'] : addslashes($_GET['categoria_link']);
}
mysql_select_db($database_MySQL_connection, $MySQL_connection);
$query_Subcategorias = sprintf("SELECT * FROM com_sub_cat WHERE ID_Cat = '%s'", $colname_Subcategorias);
$Subcategorias = mysql_query($query_Subcategorias, $MySQL_connection) or die(mysql_error());
$row_Subcategorias = mysql_fetch_assoc($Subcategorias);
$totalRows_Subcategorias = mysql_num_rows($Subcategorias);
?>

<tr>
<td><a href="lojas.php?sub_categorias=<?php echo $row_Subcategorias['ID_Sub_Cat']; ?>"><?php echo $row_Subcategorias['Nome_Sub_Cat']; ?></a></td>
</tr>
<?php } while ($row_Subcategorias = mysql_fetch_assoc($Subcategorias)); ?>
</table>
</body>
