我在详细信息页面上创建了一个删除按钮,删除了必须删除的值....删除后似乎代码正常工作,因为它不会在详细信息页面上显示任何信息但是当我去的时候到PHPMyAdmin它仍然显示一些值...我使用三个表人,地址,简历后按删除人的值被删除但不是从地址和简历。
我的删除代码:
<?php
$servername = "localhost";
$username = "root";
$password = "usbw";
$dbname = "persons";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$id=$_GET['id'];
$stmt = $conn->prepare('DELETE FROM person WHERE person_id = ?');
$stmt->bind_param('s', $id);
$result = $stmt->execute();
if ($result === FALSE) {
die("Error: " . $stmt->error);
}
$conn->close();
?>
我在CASCADE上为address_id和cv_id设置了ON DELETE,它与person_cv和person_address有关系。此外,我不想为这个小问题开始一个新主题......当我按下删除时,它会转到一个名为http://localhost:8080/Website/delete.php?id=(randomid)的空白页面。我希望它返回到详细信息页面。

检查foreignKey Cascade
<?php
$servername = "localhost";
$username = "root";
$password = "usbw";
$dbname = "persons";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$id=$_GET['id'];
if ($conn->query(sprintf ( "DELETE FROM person WHERE person_id = '%s' ", mysql_real_escape_string ( $id ) ) )) {
header('Location: detailpage.php');
}
else{
printf("Errormessage: %s\n", $mysqli->error);
exit();
}
$conn->close();
?>
