我目前正在从事一个项目，但不幸的是，我现在需要向通过php从mysql获取的表内容添加一个编辑功能

假设我有一张桌子：

id名称城市

1克里斯·米兰
2玛雅都灵

我希望增加一项功能，用户可以直接编辑特定行的内容，因此类似于

id名称城市
1克里斯米兰编辑部
2玛雅都灵编辑

我查阅了很多教程，但无法理解它们的过程

这是我的密码：

<?php
require_once 'welcome.php';
?>
<?php
echo "<table style='width: 600px; border: solid 1px black; padding: 10px'>";
 echo "<tr><th>Id</th><th>Codice Cliente</th><th>Data</th><th>Tipo di Trattamento</th><th>Note Trattamento</th><th>Costo Trattamento</th><th>Offerta</th><th>Rivendita</th><th>Note rivendita</th><th>Prezzo</th><th>Action</th></tr>";

class TableRows extends RecursiveIteratorIterator {
    function __construct($it) {
        parent::__construct($it, self::LEAVES_ONLY);
    }

    function current() {
        return "<td style='width: 190px; border: 1px solid black;'>" . parent::current(). "</td>";
    }

    function beginChildren() {
        echo "<tr>";
    }

    function endChildren() {
        echo "</tr>"  . "\n";
    }
}


$servername = "localhost";
$username = "e";
$password = "0";
$dbname = "e";

try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $codice_cliente = filter_var($_POST["codice_cliente"], FILTER_SANITIZE_NUMBER_INT);
    $data = $_POST["data"];
    $user_id = $_POST["user_id"];
    $edit= $_POST["edit"];

    $stmt = $conn->prepare("SELECT id, codice_cliente, data, trattamento, note_trattamento, costo_trattamento, offerta, rivendita, note_rivendita, prezzo FROM Dati_Clienti WHERE user_id='Beauty' AND (codice_cliente='$codice_cliente' OR data='$data')");
    $stmt->execute();

    // set the resulting array to associative
    $result = $stmt->setFetchMode(PDO::FETCH_ASSOC);

    foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) {
        echo $v ;
    }
}
catch(PDOException $e) {
    echo " ". $e->getMessage();
}
$conn = null;
echo "</table>";
?>


为了在mysql中编辑记录，我们使用UPDATE
语句
例如：
# Update the name for record 1
UPDATE Persons
SET name='Jane Doe'
WHERE id=1;

因为您使用的是PHP，所以您可能知道如何执行查询。所以理论上你只需要以下几点
示例代码

身份证件
名称
城市

要编辑：
<?php
/**
 * edit.php
 */

// If the form is submitted
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $stmt = "UPDATE Persons
    SET name='".$_POST['name']."',
    city='".$_POST['city']."'
    WHERE id='".$_POST['id']."'
    LIMIT 1
    ";

    $database->execute($stmt);

    echo "Data saved";
    exit;
}

// Get the data for the chosen record to edit
$personId = $_GET['id'];

$stmt = "SELECT
*
FROM Persons
WHERE id='".$personId."'
";

// Again, get your data
$person = $database->execute();
?>

<!-- Your form -->
<form action="<?= $_SERVER['PHP_SELF']; ?>" method="POST" role="form">
    Name: <input type="text" name="name" value="<?= $person['name']; ?>"><br />
    City: <input type="text" name="city" value="<?= $person['city']; ?>"><br />
    <input type="hidden" name="id" value="<?= $person['id']; ?>">
    <button type="submit" class="btn btn-primary">Submit</button>
</form>

如果有人遇到这种情况，这里有一个我必须开发的快速代码，它工作得非常完美

    border: 1px solid black;

$servername = "localhost";
$username = "un";
$password = "up";
$dbname = "dbn";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
$codice_cliente=$_POST["codice_cliente"];
$data=$_POST["data"];

$sql = "SELECT id, codice_cliente, data, trattamento, note_trattamento, costo_trattamento, offerta, rivendita, note_rivendita, prezzo FROM Dati_Clienti WHERE (codice_cliente='$codice_cliente' OR data='$data')AND user_id='Beauty'";
$result = $conn->query($sql);

if (empty($codice_cliente) && empty($data)){
      echo ("<br/><font color='red'><center> Enter either cliente code or date!</center></font>");
} else {
if ($result->num_rows > 0) {
    echo "<table><tr><th>Codice Cliente</th><th>Data</th><th>Trattamento</th><th>Note</th><th>Costo Trattamento(€)</th><th>Offerta</th><th>Rivendita</th><th>Note</th><th>Prezzo(€)</th></tr>";
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "<tr><td>" . $row["codice_cliente"]. "</td><td>" . $row["data"]. "</td><td>" . $row["trattamento"]. "</td><td>" . $row["note_trattamento"]. "</td><td>" . $row["costo_trattamento"]. "</td><td>"

    }
    echo "</table>";

    echo "0 results";

有什么不符合你的要求？没有提到这一点，或者有任何错误。你没有为此发布html/表单，所以我们不知道这是否可以。嗨，funk，事情是在表中添加编辑选项，我可以通过创建一个编辑表单，然后制作一个php端来执行此操作来实现这一点，但是直接将此添加到表中是个问题，我以前没有这样做过，希望你现在就了解我Hiya！好的，下面有一个答案，您可以尝试，但要注意，您的代码对sql注入是开放的。你最好使用一个准备好的语句。好的，谢谢pete，我现在就试试，非常感谢Mate。我已经在我的确切项目中修改了代码，但它现在只显示了一个空白页，我将在这里粘贴代码，'可能我忘了指出查询是根据用户提供的详细信息执行的，（即日期和代码）ID codice_客户数据策略尝试使用ini_集（“显示错误”，“打开”）启用错误报告和错误报告（E_ALL）
