Take out your customer route - you don't need it. Just use links in the format:
echo $this->Html->link(
'Text',
array(
'controller' => 'controller_name',
'action' => 'action_name',
$variable
)
);
Cake will sort the rest out for you. $variable can be the id if you want, or
the category.
The reason you are getting the funny url is because you are specifying names
for the third and forth parameters (id and category), so they appear with a
colon before them. If you really insist on sending over two parameters, just do
this:
echo $this->Html->link(
'Text',
array(
'controller' => 'controller_name',
'action' => 'action_name',
$variable,
$category
)
);
Your receiving action will just match the variables with the parameters in
expects in order:
function action($variable = null, $category = null) {}
The same holds true for a redirect, where the syntax would be:
$this->redirect(
array(
'controller' => 'controller_name',
'action' => 'action_name',
$variable,
$category
)
);
Note that the 'Text' has gone but the array is the same.
