[Solved] codeigniter pagination question

#1
When I view my table it shows a list of my files controllers. But inside that list I have a $data['controller_files'] = array();

Is it possible to some how make the controller_files array work with the codeigniter pagination.

On the view I have set up foreach ($controller_files as $controllers) {}

$route['admin/extension/permissions'] = "admin/extension/extension_permissions/index";
$route['admin/extension/permissions/(:any)'] = "admin/extension/extension_permissions/index/$1";

I have attached the files

Sure, the pagination library is agnostic and can be used for anything that needs pagination, whether it's coming from the db, a xml feed, files on your server, images, whatever. It doesn't care what kind of data it is. All it's doing is creating links to pages based on:
1) the max number of entities you are trying to paginate
2) how many "per page" you set to view
3) what the current page number you are on is.

I haven't looked at your code, and I won't give a complete answer as I have no idea what your actual data looks like, but let's say your $data['controller_files'] array looked like this:

PHP Code:
$data['controller_files'] = array(
  
'item 1',
  
'item 2',
  
'item 3',
  
'item 4',
  
'item 5',
  
'item 6'
); 

And you wanted your pagination to display 2 items per page. You could just use array_chunk().
PHP Code:
$data['controller_files'] = array_chunk($data['controller_files'], 2); //2 for how many per page to display 

Now your array will look like:
PHP Code:
array(
  
=> array(
    
'item 1',
    
'item 2'
  
),
  
=> array(
    
'item 3',
    
'item 4'
  
),
  
=> array(
    
'item 5',
    
'item 6'
  
)
); 

As you can see it broke it up into sub arrays with each containing 2 entries from the original array (the number per/page you want to display), and we have 3 total pages (3 arrays within the main array). To get total number of pages that you'd use in the pagination config, you'd just use the value from count($data['controller_files']), which will return 3.

Now if you want to display page 1, you'd just send to the view:
PHP Code:
$data['controller_files'][0]; //which is item 1, item 2 

If you wanted to display page 3, you'd send:
PHP Code:
$data['controller_files'][2]; //which is item 5, item 6 

Hope that gets you on the right track.

You mean some thing like this Working
