PHPでボタンがクリックされたときの動的ボタンの値の取得方法

私はPHPで動的ボタンを作成しました。特定のボタンがクリックされたときに、そのボタンの値を取得する必要があります。ボタンをクリックすると、すべての情報がフォームに取り込まれます。ここで PHPでボタンがクリックされたときの動的ボタンの値の取得方法

<?php 

function dash() 
{ 
    include 'config.php'; 
    $sql = "SELECT roomno FROM roombook"; 

    if($result = mysqli_query($db, $sql)) 
    { 
      $str = ''; 

      while($row = mysqli_fetch_array($result)) 
      { 
       // generate array from comma delimited list 
       $rooms = explode(',', $row['roomno']); 

       //create the dynamic button and set the value 
       foreach ($rooms as $k=>$v) 
       { 
        $str .= '<input type="button" onClick="showDiv()" name="btn_'.$k.'" value="'.$v.'" id="btn_'.$k.'"/>'; 
       } 
      } 

      return $str; 
     } 
     else { 
      echo "ERROR: Could not able to execute $sql. " . mysqli_error($db); 
      } 

    mysqli_close($db); 
} 
?> 

<!Doctype html>

    <meta charset="UTF-8"> 
    <title>room boking</title>

<body> 
<form method="post" action=""> 
<div class =" row box col-md-4" > 
<div style="color:black"><?php echo dash();?></div> 
</div> 

</form>

フォームコードの値を取得するための私のコードです。この

$str .= '<input type="button" onClick="showDiv()" data-atribute-id="valueyouwant" name="btn_'.$k.'" value="'.$v.'" id="btn_'.$k.'"/>';

スクリプトは

ようにする必要があります

$("button").click(function() { 
    alert(this.id); OR 
    alert($(this).attr('id')); OR 
    alert($(this).attr('data')); OR 
    var btnid = $(this).attr('data');//which give you current clicked btn id 
});

あなたはこれを使用することができます助けることができる

// is going to select all elements that its name start with *btn_* (your dynamic buttons) 

$('[name^="btn_"]').click(function() { 
    //get the value of the button that was clicked 
    var buttonValue = $(this).val(); 

    // send data to the other file using the action attribute of the form 
    $('form').submit(); 
});

希望を。
