The server stores a version of the result so that, on subsequent
requests, it need not request the data from the DB, filter it, turn it
into a view (the HTML). Although there are several different types of
caching with Cake, including caching queries or caching the entire
view.

Also, there are different types caching engines one can use. The
config is in app/config/core.php. The most basic is file, which
stores the cache as files (big surprise). MemCache uses, as the name
suggests, the server's memory. That's the one i prefer but it involves
installation on the server. If you do not control your own server,
this option is likely not available. But it couldn't hurt to ask you
hosting company if it is. APC may also be available.

Anyway, the basic idea would be to check the cache in your action and,
if available, return that. Otherwise, do a find() as normal and write
the result to the cache.

How can I build a navigation menu in cakephp?

2009-09-24 Thread Barney 

first, I am very new to cakephp.

I have 2 tables categories and products

I want to make a menu like category-product tree

in the view,  i use those code to display the categories:

ul
?php foreach($categories as $category): ?
li
?php echo $category['Category']['name']; ?
/li

?php endforeach; ?
/ul

But if I want to add links to these categories

how can I use $html-link to achieve it?


$html-link('$category['Category']['name']',array
('controller'='Products','action'='view', $category['Products']
['id']));


but this line code goes error,

I know $html-link first parameter should be a string value, how can I
assign a variable ?


please help,thank you

 Remove the single quotes. $category['Category']['name'] is already a
 string so you don't need them. What you'd done is passed the literal
 string, '$category['Category']['name']'.

 As for creating a menu, once you have something working, you might
 want to look at caching the result so you're not hitting the database
 on every page view.
