This is my link:

```
<td><a href="repondre.php?id=<?php echo $user['id'] ?>;">Repondre</a></td>

```

I want to display the result in my input text in the other page:

```
$id=isset($_GET['id']);
$reponse = $conn->query("SELECT * FROM demande_client where id='$id'");
$user = $reponse->fetch();
?>
<form action="" method="get">
<label for="field2"><span>Email <span class="required">*</span></span><input type="text" class="input-field" name="email" value="<?php echo $user['mail']; ?>" /></label>

```

I always get nothing in the textbox. What is going wrong, and how do I fix it?
