我有php頁面,可以查看,添加,刪除數據庫中的記錄,但是我無法使其工作來編輯記錄。我有問題要id到edit_h.php。當我在(「更新uzytkownik SET LOGIN =:登錄WHERE ID = :ID」)手動輸入ID號時,它可以正常工作。我現在一直堅持這個問題。感謝您的任何建議幫助。獲取編輯記錄的ID PHP + Oracle
這裏是我的代碼:
edit.php
<?php
session_start();
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Edytowanie uzytkownikow</title>
</head>
<body>
<form action="edit_h.php" method="post">
Login:<br>
<input type="text" name="login">
<br>
<input type="submit" value="Edytuj">
</form>
</body>
</html>
edit_h.php
<?php
include_once "polacz.php";
$id = $_GET['id'];
$login = $_POST['login'];
$con = polacz();
$stid = oci_parse($con, "UPDATE uzytkownik SET LOGIN = :login WHERE id = :id");
oci_bind_by_name($stid,':login',$login);
oci_bind_by_name($stid,':id',$id);
if (oci_execute($stid))
{
header("Location: view.php");
}
else
{
echo "blad";
}
view.php
<?php
include_once "polacz.php";
session_start();
if (!isset($_SESSION['id']))
{
header("Location: login.php");
die();
}
?>

<?php

echo '<br><a href="logout.php">WYLOGUJ SIĘ</a><br>';
$con = polacz();
if (isset($_GET['sort']))
{
$sort = (int)$_GET['sort'];
if ($sort == 1)
{
$sort = 2;
}
else
{
$sort = 1;
}
}
else
{
$sort = 1;
}
$dbsort =array(1=>'ASC',2=>'DESC');
$stid = oci_parse($con,"SELECT id, login FROM uzytkownik ORDER BY login ".$dbsort[$sort]);
oci_execute($stid);
echo "<table>";

$login = $row['LOGIN'];
echo "<tr><td>$id</a></td><td>$login</td>

}
echo "</table>";
echo '<br><a href="add.php">Dodaj uzytkownika</a><br>';
?>

那麼,你期望'$ _GET ['id']'應該來自edit_h.php?不過,你可以在'edit.php'中找到它,所以你需要把它作爲隱藏的輸入包含在其中。 – Jeff
