Question

I am, using the Codeigniter pagination library,

I am wondering how I can grab the number of the first and last items displayed using the pagination class?

So, if I had 12 results, and per_page was set to 5. I would want

Page 1: Displaying 1 to 5 of 12 results
Page 2: Displaying 6 to 10 of 12 results
Page 3: Displaying 11 to 12 of 12 results.

Answer 1

Keeping it simple.

You need 3 variables. Result start, result end (in the page, not the whole) and total result.

1. You already know the total results (from the pagination). Let’s call it $total.

2. so, now get the current page ($curpage) value from CI instance. Then,

   $result_start = ($curpage - 1) * $per_page + 1;
   if ($result_start == 0) $result_start= 1; // *it happens only for the first run*
   

3. for $result_end, you just need to add the per page value but considering it’ll be 1 less,

   $result_end = $result_start+$per_page-1;
   
   if ($result_end < $per_page)   // happens when records less than per page  
       $result_end = $per_page;  
   else if ($result_end > $total)  // happens when result end is greater than total records  
       $result_end = $total;
   

4. send all those 3 values to view.

   echo "displaying $result_start to $result_end of $total";
