將功能綁定到循環中的onclick按鈕

Question

我有一個嵌套在表格中的表格，如下所示：

從上述文件接收發布請求的“ leave_request_processor.php”文件如下所示：

$approved = "Approved";

$rejected = "Rejected";

foreach($all_leave_ids as $leave_id){

    if(isset($_POST["approve"])){

    $strQuery2 = "UPDATE leave_applications SET status = '$approved' WHERE application_id = '$leave_id' ";

    $result2 = mysqli_query($connection,$strQuery2) or Exit ("Query execution failed");

    mysqli_close($connection);

    header("Location: leave_check.php"); /* Redirect browser */

    exit();

        }

    else if (isset($_POST["reject"])){

    $strQuery3 = "UPDATE leave_applications SET status = '$rejected' WHERE application_id = '$leave_id' ";

    $result3 = mysqli_query($connection,$strQuery3) or Exit ("Query execution failed");

    mysqli_close($connection);

    header("Location: leave_check.php"); /* Redirect browser */

    exit();

    }

   }

該代碼有效，但是從第一行（單擊的任何行的按鈕）開始按降序排列，然后重新加載頁面，剩下未決的請求。

我敢打賭，有一種方法可以對它進行編碼（我在考慮JavaScript），這樣，如果我在第23行單擊“批准”，它將作用於該行。 有人知道我能做到這一點嗎？

@Rasclatt我嘗試了這個。 這就是您的想法嗎？ 沒用。

$strQuery = "SELECT * from leave_applications WHERE status = 'Pending' ";

$result = mysqli_query($connection, $strQuery) or Exit("Query execution failed");

if($result->num_rows>0){


    // output data of each row

echo "<table class='pure-table pure-table-bordered'>
<thead>
    <tr>
        <th>Application ID</th>
        <th>Student ID</th>
        <th>Email</th>
        <th>Days Requested</th>
        <th>Status</th>
        <th colspan='2'>ACTION TO TAKE</th>
    </tr>
</thead>";

while($row = $result->fetch_assoc()){

    array_push($allleaveids,$row["application_id"]);

    echo 
"<form action='leave_request_processor.php' method='post' target='_self' name='leave_check' class='pure-form pure-form-aligned'>
    <tr>
    <td>".$row["application_id"]."</td>
    <td>".$row["student_id"]."</td>
    <td>".$row["email"]."</td>
    <td>".$row["days_requested"]."</td>
    <td>".$row["status"]."</td>
    <td><button class='button-success pure-button' name='approve' type='submit'>Approve</button></td>
    <td><button class='button-error pure-button' name='reject' type='submit'>Reject</button></td>
    </tr>
    </form>";   
echo "</table>";
}   

}
