我在一个网站上工作，我想在 url 上显示 ID 号并获取它的属性(例如用户名、名字、姓氏)
例如，如果我输入:localhost/search/index3.php?u=3，它会在页面上的文本字段中显示数据库值。
这是我的 .htaccess 的代码
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.*)$ http://localhost/search/index3.php?u=$1 [NC]
这是我的其余代码
<?php
$host = "localhost";
$user = "root";
$password ="";
$database = "ntmadb";
$id = "";
$firstname = "";
$lastname = "";
$username = "";
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
// connect to mysql database
try{
$connect = mysqli_connect($host, $user, $password, $database);
} catch (mysqli_sql_exception $ex) {
echo 'Error';
}
// get values from the form
function getPosts()
{
$posts = array();
$posts[0] = $_POST['id'];
$posts[1] = $_POST['firstname'];
$posts[2] = $_POST['lastname'];
$posts[3] = $_POST['username'];
return $posts;
}
// Search
if(isset($_POST['search']))
{
$data = getPosts();
$search_Query = "SELECT * FROM members WHERE id = $data[0]";
$search_Result = mysqli_query($connect, $search_Query);
if($search_Result)
{
if(mysqli_num_rows($search_Result))
{
while($row = mysqli_fetch_array($search_Result))
{
$id = $row['id'];
$firstname = $row['firstname'];
$lastname = $row['lastname'];
$username = $row['username'];
}
}else{
echo 'No Data For This Id';
}
}else{
echo 'Result Error';
}
}
// Insert
if(isset($_POST['insert']))
{
$data = getPosts();
$insert_Query = "INSERT INTO `members`(`firstname`, `lastname`, `username`) VALUES ('$data[1]','$data[2]','$data[3]')";
try{
$insert_Result = mysqli_query($connect, $insert_Query);
if($insert_Result)
{
if(mysqli_affected_rows($connect) > 0)
{
echo 'Data Inserted';
}else{
echo 'Data Not Inserted';
}
}
} catch (Exception $ex) {
echo 'Error Insert '.$ex->getMessage();
}
}
// Delete
if(isset($_POST['delete']))
{
$data = getPosts();
$delete_Query = "DELETE FROM `members` WHERE `id` = $data[0]";
try{
$delete_Result = mysqli_query($connect, $delete_Query);
if($delete_Result)
{
if(mysqli_affected_rows($connect) > 0)
{
echo 'Data Deleted';
}else{
echo 'Data Not Deleted';
}
}
} catch (Exception $ex) {
echo 'Error Delete '.$ex->getMessage();
}
}
// Edit
if(isset($_POST['update']))
{
$data = getPosts();
$update_Query = "UPDATE `members` SET `firstname`='$data[1]',`lastname`='$data[2]',`username`='$data[3]' WHERE `id` = $data[0]";
try{
$update_Result = mysqli_query($connect, $update_Query);
if($update_Result)
{
if(mysqli_affected_rows($connect) > 0)
{
echo 'Data Updated';
}else{
echo 'Data Not Updated';
}
}
} catch (Exception $ex) {
echo 'Error Update '.$ex->getMessage();
}
}

最佳答案
你在引用
if(isset($_POST['search']))
用于获取“已发布”参数(通常来自表单)。
您需要查看 $_GET['u'] 以获取传入的 id。
编辑:只是通读代码，还有一些其他错误，因为以下位来自用户发布表单的示例。 (即 getPost() 位)。如果您尝试根据传入的 ID 从数据库中获取详细信息，则不需要它。
if (isset($_GET['u'])) {
if ($stmt = $mysqli->prepare("SELECT * FROM members WHERE id = ?")) {
/* bind parameters for markers */
$stmt->bind_param("i", $_GET['u']);
/* execute query */
$stmt->execute();
if ($stmt->affected_rows) {
// Deleted
} else {
// Not found / deleted
}
}
}
