我想预先填写一个应该编辑数据库中条目的表单。当我单击一行中的“编辑”时，模式应显示为预填充表单。到目前为止，一切工作正常，但我不知道如何更改我的代码以获得预填充表单的Modal。
<?php $page='database'; $php='yes'; $title='Datenbank' ; include( 'header.php'); ?>
<body>
<?php include( 'menu.php'); ?>
<div class="container">
<h1>Datenbank</h1>
<button class="btn btn-default" data-toggle="modal" data-target="#addToDatabase">Neuer Eintrag</button>
<br><br>
<p style="font-size: 16px; "><strong>Datenbankeinträge</strong></p>
<?php
$servername = "localhost";
$username = "xxx";
$password = "*******";
$dbname = "xxx";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT id, name, year, regie, actors, length FROM films";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "<div style=\"overflow: auto\"><table> <tr> <th>ID</th> <th>Filmname</th> <th>Jahr</th> <th>Regie</th> <th>Schauspieler</th> <th>Länge [Minuten]</th> <th><a data-toggle=\"modal\" data-target=\"#updateDatabase \"><i class=\"glyphicon glyphicon-pencil\"></i></a></th> </tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
$id = $row["id"];
echo "<tr><td>". $row["id"]. "</td><td>". $row["name"]. "</td><td>". $row["year"] . "</td><td>". $row["regie"] . "</td><td>". $row["actors"] . "</td><td>". $row["length"] . "</td><td><a data-toggle=\"modal\" data-target=\"#updateDatabase \"><i class=\"glyphicon glyphicon-pencil\"></i></td></tr>";
}
} else {
echo "Noch keine Einträge vorhanden. Bitte welche hinzufügen...";
}
echo "</table></div>";
$conn->close();
?>
