Hi, I am pretty new to CodeIgniter and PHP in general and have two questions that are somewhat related.
I have a nested category tree with unlimited depth that produces links like myapp.com/language and myapp.com/spanish but I would like to have something like myapp.com/language/spanish.
For reference my model returns an array of arrays like:
[Languages] => Array ( [category_id] => 4 [sub] => Array ( [Japanese] => Array ( [category_id] => 5 ) [Spanish] => Array ( [category_id] => 6 )...
My helper function to create the menu:
function buildMenu($menu_array, $is_sub=FALSE){
/*
* If the supplied array is part of a sub-menu, add the
* sub-menu class instead of the menu ID for CSS styling
*/
$attr = (!$is_sub) ? ' id="menu"' : ' class="submenu"';
$menu = "<ul$attr>\n"; // Open the menu container
/*
* Loop through the array to extract element values
*/
foreach($menu_array as $id => $properties) {
/*
* Because each page element is another array, we
* need to loop again. This time, we save individual
* array elements as variables, using the array key
* as the variable name.
*/
foreach($properties as $key => $val) {
/*
* If the array element contains another array,
* call the buildMenu() function recursively to
* build the sub-menu and store it in $sub
*/
if(is_array($val))
{
$sub = buildMenu($val, TRUE);
}
/*
* Otherwise, set $sub to NULL and store the
* element's value in a variable
*/
else
{
$sub = NULL;
$$key = $val;
}
}
/*
* If no array element had the key 'url', set the
* $url variable equal to the containing element's ID
*/
if(!isset($url)) {
$url = $id;
}
/*
* Use the created variables to output HTML
*/
$menu .= "<li><a href='$url'>$url</a>$sub</li>\n";
/*
* Destroy the variables to ensure they're reset
* on each iteration
*/
unset($url, $display, $sub);
}
return $menu . "</ul>\n";
This leads me to my next problem. How do I get these links to call a dynamic function that can return a list of all posts in that category. I am thinking that if I can get the routes working how I want them above that it will be as easy as having a function like get_cat_posts($cat_id). Am I correct in this assumption? Will having more than one sub-level be a problem?
Sorry for the long post. Thanks for any help.
