如何在分页中保持单选按钮的选中值？

Question

How will I make stay and hold the value of the checked radio button when I go to the next page? should I use session method? Here's my code:

include('includes/dbconn2.php');

// PAGINATION
if(isset($_GET['pageno'])){
    $pageno = $_GET['pageno'];
}else{
    $pageno =1;
}

$no_of_records_per_page = 5;
$offset = ($pageno-1) * $no_of_records_per_page; 
// get no of total no. pages
$total_pages_sql = "SELECT COUNT(item_id) AS total FROM items WHERE cat_id = 4";
$result = $conn->query($total_pages_sql);
$total_rows = $result->fetch_assoc();
// calculate total pages with results
$total_pages = ceil($total_rows['total'] / $no_of_records_per_page);
// sql query for pagination
$get_items = "SELECT item_id, item_name FROM items WHERE cat_id = 4 LIMIT $offset, $no_of_records_per_page";
if($results=$conn->query($get_items)){
    while($row=$results->fetch_assoc()){
        $app_id=$row['item_id'];
        $app_name=$row['item_name'];
        ?>
        <tr> 
            <td><?php echo $app_name; ?> </td>
            <td> <label class="container"><input type="radio" name="<?php echo $app_name?>-<?php echo $app_id; ?>" value="P0"><span class="checkmark"></span></label> </td>
            <td> <label class="container"><input type="radio" name="<?php echo $app_name?>-<?php echo $app_id; ?>" value="P1"> <span class="checkmark"></span></label></td>
            <td> <label class="container"><input type="radio" name="<?php echo $app_name?>-<?php echo $app_id; ?>" value="P2"> <span class="checkmark"></span></label></td>             
        </tr>
        <?php                        
    }
    $results->close();
}

Answer 1

• You could use $_SESSION["values"] = "SOMETHING";
• Another method could be <input type="checkbox" name="pagination" value="SOMETHING" hidden> inside a form
• And the last and most insecure resourse is sending info through URL like this <a href="nexturl.php?values=SOMETHING" and in the page that you want to get the info, you have to use $_GET['values']
• after that, you can use inside the checkbox <input type="checkbox" name="whaTever" value="SOMEVALUE" checked>
