<?php
define('TITLE', 'Requests');
define('PAGE', 'rontgenDoc');
include('includes/header.php'); 
include('../dbConnection.php');
session_start();
 if(isset($_SESSION['is_adminlogin'])){
  $aEmail = $_SESSION['aEmail'];
 } else {
  echo "<script> location.href='login.php'; </script>";
 }
?>
<div class="col-sm-4 mb-5">
  <!-- Main Content area start Middle -->
  <?php 
 $sql = "SELECT file_name, hastaAdi, request, requestDetail FROM images";
 $result = $conn->query($sql);
 if($result->num_rows > 0){
  while($row = $result->fetch_assoc()){
   echo '<div class="card mt-5 mx-5">';
   echo '<div class="card-header">';
   echo 'Hasta Adı : '. $row['hastaAdi'];
   echo '</div>';
   echo '<div class="card-body">';
   echo '<h5 class="card-title">Request Info : ' . $row['request'] . '</h5>';
   echo '<p class="card-text">Açıklama: ' . $row['requestDetail'] . '</p>';
   echo '<p class="card-text">Röntgen Görseli: <img id="myImg" width="100" height="100" src="../patient/uploads/' . $row['file_name'] . '"></p>';
   echo '<div class="float-right">';
   echo '<form action="" method="POST"> <input type="hidden" name="id" value='. $row["hastaAdi"] .'><input type="submit" class="btn btn-info mr-3" name="view" value="View"><input type="submit" class="btn btn-secondary" name="close" value="Close"></form>';
   echo '</div>' ;
   echo '</div>' ;
   echo'</div>';
   $num = 12;
   echo '
   <form action="docYorum.php" method="post" enctype="multipart/form-data">
    <div class="col-sm-9 col-md-12 mt-5">
      <form class="mx-10" action="" method="POST">
        <div class="form-group">
          <label for="docYorum">Doktor Değerlendirmesi</label>
          <input type="text" class="form-control" id="docYorum" placeholder="Doctor Yorumu" name="docYorum" value="'.$row['id'].'">
        </div>
        <button type="submit" class="btn btn-info" name="submit">Gönder</button>
  </form>
   
   ';
  }
 } else {
  echo '<div class="alert alert-info mt-5 col-sm-6" role="alert">
  <h4 class="alert-heading">Well done!</h4>
  <p>Aww yeah, you successfully assigned all Requests.</p>
  <hr>
  <h5 class="mb-0">No Pending Requests</h5>
</div>';
 }
?>
<?php
include('includes/footer.php'); 
$conn->close();
?>

docYorum.php:

<?php
// Include the database configuration file
include('dbConnection.php');
session_start();
$r=session_id();
$statusMsg = '';
$sql = "SELECT file_name FROM images";
$result = $conn->query($sql);
$docYorum = $_REQUEST['docYorum'];
if($result->num_rows > 0){
 while($row = $result->fetch_assoc()){
    if(isset($_POST["submit"]) ){
        $fileName=$row["file_name"];
        $insert = $conn->query("UPDATE images SET docYorum='$docYorum' WHERE id='..'");

 }
}
}

            

// Display status message
echo $statusMsg;
?>
<script>console.log(<?php echo $sql?>)</script>

Answer

this form in rontgenDoc.php should be like

<form action="docYorum.php" method="post" enctype="multipart/form-data">
    <div class="col-sm-9 col-md-12 mt-5">
        <div class="form-group">
          <label for="docYorum">Doktor Değerlendirmesi</label>
          <input type="text" name="id" hidden value="'.$row['id'].'">
          <input type="text" class="form-control" id="docYorum" placeholder="Doctor Yorumu" name="docYorum" value="">
        </div>
        <button type="submit" class="btn btn-info" name="submit">Gönder</button>
   </div>       
</form>

docYorum.php should be like

<?php
// Include the database configuration file
include('dbConnection.php');
session_start();
$r=session_id();
$statusMsg = '';
if(isset($_POST["submit"]) ){
    $id = mysqli_real_escape_string($conn,$_POST['id']);
    $docYorum = mysqli_real_escape_string($conn,$_POST['docYorum']);
    $fileName=$row["file_name"];
    $insert = $conn->query("UPDATE images SET docYorum='$docYorum' WHERE id='$id';");

 }
?>
