Merhabalar,
<button data-id="<?=$row['id']?>" onclick="$('#dataid').val($(this).data('id')); $('#acmod').modal('show');" >click me</button>
Buradan Gelen id noyu

$islem = $oku->execute(array("idisi" => "9"));

9 yazan yere aktarıp modal da veriyi getirmek istiyorum.

<table id="example" class="display nowrap" style="width:100%">
        <thead>
            <tr>
                <th>id</th>
                <th>TC No</th>
                <th>İşlem</th>
            </tr>
        </thead>
        <tbody>
            <tr>        
                <?php
$toku = $db->query("SELECT * FROM deneme ORDER BY id desc", PDO::FETCH_ASSOC);
if ( $toku->rowCount() ){
foreach( $toku as $row ){?>
                <td><?=$row['id']?></td>
                <td><?=$row['tc_no']?></td>
                <td>
                <button data-id="<?=$row['id']?>"  onclick="$('#dataid').val($(this).data('id')); $('#acmod').modal('show');" >click me</button>
                </td>
            </tr> 
        <?php
    }
}

?>
        </tbody>
    </table>
