รบกวนหน่อยค่ะ จะส่งค่า array ใน Datatable ไปในaction form ยังไงให้ค่าแสดงตามมา

<form id="form1" action="process.php" method="post"  >  
    <table  id="example" class="table table-bordered table-hover" >  
	
                  <thead>
                  <tr>
                    <th>No</th>
                    <th>Code</th>
                    <th>Description</th>
                    <th>Action</th>
                  </tr>
                  </thead>
				  <tbody>
<?php
$sql="SELECT count(id_data	) FROM t_data WHERE (name = '$name') ";
$query=odbc_exec($link,$sql);
$num=odbc_result($query,1);
										  
$sql_a="SELECT * FROM t_data WHERE (name = '$name')  ";							 
$query1=odbc_exec($link,$sql_a);
for($p=1;$p<=$num;$p++) {
$rows=odbc_fetch_array($query1);									
$id = $rows['id'];	
$id_a = $rows['id_a'];	
$txt = $rows['txt'];	
$name = $rows['name'];	
?>	
                  <tr>
                    <td> </td>
                    <td><?php echo $id; ?></td>
                    <td><?php echo $name; ?></td>
                    <td align = "center"><input type="checkbox" name="r2[]" id="r2[]"  value="<?php echo $id_a; ?>" ></td>
				     <input type="hidden" name="user" id="user" value="<?php echo $user; ?>">
				  </tr>	
<?php
}
?>
                  </tbody>
                </table>
<button type="submit" id="submit" name="submit" class="btn btn-success ">
