Can anyone provide advice with my pagination php code?

Hey guys, I am creating a way to display products on a page with page numbering, I am aiming that each page will contain the next amount of products. For testing purposes, I have 14 products in my table and I have set the items per page to 1 so that generates 14 pages, but when I click on a different page it just always displays the same product. Here is my code:

if($main == go){

			
			if (isset($_GET["page"])) { 
			
			$page  = $_GET["page"]; 
			
			} 
			else { 
			$page=1; 
			$_GET["page"] = 1; 
			} 
			$start_from = ($page-1) * $pageitems; 
			
			
			$pageitems = 1;
			
							//SQL to calculate amount of pages need for product listing
				$sql2 = "SELECT COUNT(productID) AS 'rowcount' FROM products";
				$stmt2 = sqlsrv_query( $conn, $sql2,array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));
				if(!$stmt2) 
				{
					die( print_r( sqlsrv_errors(), true));
				}	while( $row2 = sqlsrv_fetch_array( $stmt2)){$total_records = $row2['rowcount'];}

				$total_pages = ceil($total_records / $pageitems);

						
			
			
			$sql = "SELECT productID, productName, category, range, price, picture, description, ROW_NUMBER() OVER(ORDER BY category) AS rownumber FROM products "; 


			//Check SQL Query		
			$stmt = sqlsrv_query( $conn, $sql,array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));
			if(!$stmt) 
			{
				die( print_r( sqlsrv_errors(), true));
			}

				while( $row = sqlsrv_fetch_array( $stmt)) 
										{							
								$rownumber = $row['rownumber'];
								$end_at = $pageitems + $start_from;
								
								if (($rownumber>$start_from)&&($rownumber<=$end_at))
								{
								
								echo '<p class="productsContent">'.$row['productName'];
								echo '<br/>'.$row['category'];
								echo '<br/>'.$row['range'];
								echo '<br/>&pound;'.$row['price'];
								echo '<br/><br/><a href="products.php?productID='.$row['productID'].'"><img  src="' . $row['picture'] .'" /></a>';
								echo '<br/><br/></p>';
											}
								
							}	

		
						for ($i=1; $i<=$total_pages; $i++) { 
						echo "<a href='products.php?main=go&page=".$i."'>".$i."</a> "; 
						} 
						
			}

I have almost finished this, but just cant figure out the last part, I feel this would have been easier using the LIMIT function, but this is not supported in SQL Server.

If anyone can help out that would be great.


Thanks!
