Hello
I have a search page where you select the letter of the alphabet
and the person's information who's name beginning with that letter is displayed.
This function is placed on the web page to search and display the information.
Everything works except one thing.
The problem is if there are 3 pages page one is OK, but when you select next to go to page two the information on page two is no displaying.
Can you see something I missed or have any suggestion?

<?php

   //db connection and selection
   $mysqli = db_connect();

   //if $_GET['page'] defined, use it as page number
   if(isset($_GET['page']))
      {
     $pageNum = $_GET['page'];
      }
   
   //counting the offset
   $offset = ($pageNum - 1) * $rowsPerPage;

I forgot this bit of code that is found under the select.

$pagingQuery = "LIMIT $offset, $rowsPerPage";
  $result = mysqli_query($mysqli,$query.$pagingQuery) or die('Error, query failed');

Thanks for the suggestions.

I have resolved the problem.
Using the next and other navigation links to pass variables via the URL that is used to retrive data from the database like the "ID" was required.
