php, sql, html, обновляющий уникальную запись с соответствующей кнопкой

Question

Я новичок в PHP и SQL и пытаюсь выяснить, как я могу заставить кнопку HTML Approve (submit) взаимодействовать с соответствующей записью. В настоящее время при нажатии кнопки «Утверждение» каждое из полей обновляется, но верхняя (первая) запись всегда обновляется. Я хотел бы, чтобы пользователь мог пропустить первую запись и обновить другую запись. Любые предложения и помощь приветствуются.

$conn = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME) or die('there was a problem connecting to the database' . mysql_error()); 

$sql = "SELECT Part, Lot, Qty, AnodTemp, Amp, SealTemp, PerformedBy, DateTimePerformed, FinalAnodThickness, QtyPass, FinalSealCheck, CheckedBy, DateTimeChecked, id FROM logs"; 

$result = $conn->query($sql); 




if ($result->num_rows > 0) 
{ 
    while($row = $result->fetch_assoc()) 
{ 
    $unapproved = $row['CheckedBy']; 
    if($unapproved == null) 
    { 

     echo "<br><br><br> Part: " . $row['Part']. "/Lot: " . $row['Lot']. "/Qty: " . $row['Qty']. "/AnodTemp: " . $row['AnodTemp']. "/Amp: " . $row['Amp']. "/SealTemp: " . $row['SealTemp']. "/PerformedBy: " . $row['PerformedBy']. "/ID: " . $row['id']; ?> 

     <form action="adminapproval.php" method="post"> 
     Final Anod Thickness:<br> 
     <input type="text" name="FinalAnodThickness"> 
     <br><br> 
     Qty Pass:<br> 
     <input type="text" name="QtyPass"> 
     <br><br> 
     Final Seal Check:<br> 
     <input type="text" name="FinalSealCheck"> 
     <br><br> 


     <input type="submit" id="submit" value="Approve" name="submit"> 
     <br><br> 
     </form> 
     _____________________________________________________________________<br> 
     <?php 

     if (isset($_POST['submit'])) 
     { 

      $FinalAnodThickness= $_POST['FinalAnodThickness']; 
      $QtyPass= $_POST['QtyPass']; 
      $FinalSealCheck= $_POST['FinalSealCheck']; 
      $CheckedBy= $_SESSION['CheckedBy']; 
      $id = $row['id']; 





      $sql = "UPDATE logs SET FinalAnodThickness = '$FinalAnodThickness', QtyPass = '$QtyPass', FinalSealCheck = '$FinalSealCheck', CheckedBy = '$CheckedBy', DateTimeChecked = now() WHERE id = $id "; 
      $conn->query($sql); 
      break; 
      $conn->close(); 
      echo "Record Updated."; 
      header("Location: adminapproval.php"); 
     } 

     } 
    } 
} 



echo "<br><br> No further items need to be approved at this time."; 


?>

TWO ФАЙЛЫ

adminapproval.php

<?php 
session_start(); 
$conn = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME) or die('there was a problem connecting to the database' . mysql_error()); 
$sql = "SELECT Part, Lot, Qty, AnodTemp, Amp, SealTemp, PerformedBy, DateTimePerformed, FinalAnodThickness, QtyPass, FinalSealCheck, CheckedBy, DateTimeChecked, id FROM logs"; 
$result = $conn->query($sql); 

if ($result->num_rows > 0){ 
while($row = $result->fetch_assoc()){ 
    $unapproved = $row['CheckedBy']; 
     if($unapproved == null){ 
      echo "<br><br><br> Part: " . $row['Part']. "/Lot: " . $row['Lot']. "/Qty: " . $row['Qty']. "/AnodTemp: " . $row['AnodTemp']. "/Amp: " . $row['Amp']. "/SealTemp: " . $row['SealTemp']. "/PerformedBy: " . $row['PerformedBy']. "/ID: " . $row['id']; ?> 

      <form action="adminapproval-exec.php?id=<?php echo $row['id']; ?>" method="post"> 
       <input type="hidden" name="id" value="<?php echo $row['id']; ?>" /> 
       <input type="hidden" name="checkedby" value="<?php echo $SESSION['CheckedBy']; ?>" /> 
       Final Anod Thickness:<br> 
       <input type="text" name="FinalAnodThickness"> 
       <br><br> 
       Qty Pass:<br> 
       <input type="text" name="QtyPass"> 
       <br><br> 
       Final Seal Check:<br> 
       <input type="text" name="FinalSealCheck"> 
       <br><br> 
       <input type="submit" id="submit" value="Approve" name="submit"> 
       <br><br> 
      </form> 
      <?php 
     } 
    } 
} else { 
    echo "<br><br> No further items need to be approved at this time."; 
} 
?> 

adminapproval-exec.php

<?php 
session_start(); 
if (isset($_POST['submit'])){ 
    $FinalAnodThickness= $_POST['FinalAnodThickness']; 
    $QtyPass= $_POST['QtyPass']; 
    $FinalSealCheck= $_POST['FinalSealCheck']; 
    $CheckedBy= $_POST['CheckedBy']; 
    $id = $_GET['id']; 
    // OR 
    // $id = $_POST['id']; 

    $sql = "UPDATE logs SET FinalAnodThickness = '$FinalAnodThickness', QtyPass = '$QtyPass', FinalSealCheck = '$FinalSealCheck', CheckedBy = '$CheckedBy', DateTimeChecked = now() WHERE id = $id "; 
    $conn->query($sql); 
    $conn->close(); 
    // echo "Record Updated."; 
    header("Location: adminapproval.php"); 
} 
?> 

Answer 2

<?php 
$server = "localhost"; 
$username = "username"; 
$password = "password"; 
$dbname = "db"; 

$con = mysqli_connect($server, $username, $password, $dbname); 
if (!$con) { 
    die("Faild: " . mysqli_connect_error()); 
} 

$sql = "UPDATE xxx SET lastname='Jan' WHERE id=2"; // This is importat 

if (mysqli_query($con, $sql)) { 
    echo "Record updated successfully"; 
} else { 
    echo "Error updating record: " . mysqli_error($con); 
} 

mysqli_close($con); 
?> 

Answer 3

 $CheckedBy= $_SESSION['CheckedBy']; 
     $id = $row['id']; 

Если строка идентификатор выходить из сессии, а? Если нет, то он всегда будет указывать на первый элемент в строке.
