我需要一点帮助，因为我卡住了，而且我对 php 和 vB.net 连接不太好......所以这是问题所在，我设法连接到 db 和 php 脚本显示我是否连接，如果用户获取/pw 是正确的，一切正常，但现在我不知道如何在显示新表单时获取该用户的数据并将其显示在标签中，就像在 db 中它有注册日期、上次登录和电子邮件一样，我想要让它们出现在我的第二个表格中。所以如果有人可以帮助我整理这些东西并设法完成目标，我将非常感激！
用户检查.php
<?php
if($_POST)
{
if(isset($_POST["username"]) && isset($_POST["password"]))
{
$connect = mysql_pconnect("localhost","username","password");
if($connect)
{
$select = mysql_select_db("mydatabase",$connect);
if($select)
{
$user = mysql_escape_string($_POST["username"]);
$pwd = mysql_escape_string($_POST["password"]);
$GetRows = mysql_query("SELECT * FROM MyTableHere WHERE username='$user' AND password='$pwd'");
$RowCount=mysql_num_rows($GetRows);
if($RowCount>0)
{
die("Correct !");
}
else
{
die("Incorrect !");
}
}
else
{
die("Unable to select database." . mysql_error());
}
}
else
{
die("Unable connect to database." . mysql_error());
}
}
else
{
die("Access Denied!");
}
}
else
{
die("Access Denied!");
}
