当我在第二页中使用GET方法时，我使用GET方法从一个页面获取的值保留在第二页中

This is my first page nfdata.php

<form action='drop.php' method='get'>
<tr>
<td ><input type="radio" name="radio" value="DGSTO 1">DGSTO 1</td>
<td><input type="submit" name="sub" value="Submit">

This is my 2nd page drop.php

<html>
<form id="form" action"drop.php" method="get">
    <select id="office" name="code">

    <?php
     include 'sql.php';
     if($div = $_GET['radio'])
     {
                     $div = $_GET['radio'];
                        $query="SELECT off_code_nf From non_filer where div_code_nf='$div' group by off_code_nf";
                        $sql = mysql_query($query);
                       // $row = mysql_fetch_assoc($sql);
                       //echo "<select name='to_user'>";
                            while ($row = mysql_fetch_assoc($sql))
                            {
                                echo "<option value='". $row['off_code_nf'] ."'>" .$row['off_code_nf'] ."</option>" ;
                            }
                        //echo "</select>" ;
     }
    
 ?>
 </select>
 <input type="submit" name="sub" value="Submit" />
 <br><br>
 
 <?php
    include 'sql.php';
    $inventory = $_GET['code'];
    $query= "SELECT * FROM non_filer WHERE off_code_nf = '$inventory' "; 
    $result = mysql_query($query);
    if ($inventory = $_GET['code'])
       {    
         echo "<table border='1'>
               <tr>
               <th>State Code</th>
               <th>GSTIN</th>
               
               </tr>";
       }
    while ( $row = mysql_fetch_assoc( $result ) )
                    {
                            $a = $row['state_code_nf'];
                            $b = $row['gstin_nf'];
                            Print("<tr >");
                           print("<td >$a</td>");
                           print("<td >$b</td>");
                    }
            print("</table>");

Use $_GET['radio_val'] when click on submit button on second page
