我有2页;我的索引和我的帐户细节。我的索引页面上有一个名为＆＃34; Account＆＃34;的按钮。点击它进入accountdetails页面。但是，它并没有将用户的信息转换为表格。我该怎么做？
索引
<?php
session_start();
$dbhost = "localhost";
$dbuser = "pc4u0fi_username";
$dbpass = "pc4upc4u1";
$dbname = "pc4u0fi_pc4u";
// Create connection
$conn = new mysqli($dbhost, $dbuser, $dbpass, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$query = "SELECT * FROM Klanten WHERE ID = '".$_GET['wijzigen_id']."'";
$result = $conn->query($query);
?>

答案 0 :(得分：0)
我建议在帐户php页面上按照这些步骤操作， 1.检查是否设置了GET [＆＃39; wijzigen_id＆＃39;]（您可以使用print_r进行打印以确认） 2.检查选择查询是否有效 3.检查$ data数组是否从db获取数据 4.尝试使用echo变量而不是
