Sorry my bad english

I am working on a project in CodeIgniter 3.1.11, the project in general is working fine and everything, but there is a problem, in my local I use xampp, and the codeigniter paging system works fine, but when publishing on my server or any server does not work, does not show the page.

It would have to show me something like that but it doesn't: (example)



I do not know what will be happening so that this is not showing it to me, and for the project it is essential that this is in operation.


here is my controller and model

Controller

            }else if($this->user->TIP == 3){
                $user = $this->user->TIP;

Yes, I know that there is a lot of code redundancy and spaghetti code, but for now I am starting in the project and later it will be debugged.

If anyone knows why this error is generated, I would appreciate it very much

What error? Copy the full error message so we can know what the problem is.

That is the problem that the log does not mark an error, it simply does not show the pagination to make the change of pages and show the rest of the information

You may need to change your uri protocol in app/Config/app.php see below.

PHP Code:

/**
 * --------------------------------------------------------------------------
 * URI PROTOCOL
 * --------------------------------------------------------------------------
 *
 * This item determines which getServer global should be used to retrieve the
 * URI string.  The default setting of 'REQUEST_URI' works for most servers.
 * If your links do not seem to work, try one of the other delicious flavors:
 *
 * 'REQUEST_URI'    Uses $_SERVER['REQUEST_URI']
 * 'QUERY_STRING'   Uses $_SERVER['QUERY_STRING']
 * 'PATH_INFO'      Uses $_SERVER['PATH_INFO']
 *
 * WARNING: If you set this to 'PATH_INFO', URIs will always be URL-decoded!
 *
 * @var string
 */
public $uriProtocol = 'REQUEST_URI';

I have modified by the different options that {REQUEST_URI, QUERY_STRING, PATH_INFO} offers and it still does not show me the pagination

[alcadio]

I was doing some tests with var_dump ($ this-> pagination-> create_links ()) and what rotorna me is string (0) "", I have no idea why this, if anyone knows, please help me with this

That means that it is not retrieving anything from the database check your queries.

See if they run in phpMyAdmin.
