PHP/MySQL编辑帐户信息

首先我有两个文件edit.php和update.php edit.php

<?php
session_start();
$_SESSION['id'] = '9';
$id = $_SESSION["id"];
$username = $_POST["username"];
$fname = $_POST["fname"];
$password = $_POST["password"];
$email = $_POST["email"];

mysql_connect('mysql13.000webhost.com', 'a2670376_Users', 'PASSWORD') or     die(mysql_error());
echo "MySQL Connection Established! <br>";

mysql_select_db("a2670376_Pass") or die(mysql_error());
echo "Database Found!<br>";

$query = "UPDATE members SET username = '$username', fname = '$fname', 
password = '$password' WHERE id = '$id'";

$res = mysql_query($query);

if ($res)
echo "<p>Record Updated $rows[id]<p>";
else
echo "Problem updating record MySQL Error: " . mysql_error();
?>

<form action="update.php" method="post">
<input type="hidden" name="id" value="<?=$id;?>"/>
ScreenName:<br> <input type='text' name='username' id='username' maxlength='25'    style='width:247px' name="username" value="<?=$username;?>"/><br>
FullName:<br> <input type='text' name='fname' id='fname' maxlength='20' style='width:248px' name="fname" value="<?=$fname;?>"/><br>
Email:<br> <input type='text' name='email' id='email' maxlength='50' style='width:250px' name="email" value="<?=$email;?>"/><br>
Password:<br> <input type='text' name='password' id='password' maxlength='25' style='width:251px' value="<?=$password;?>"/><br>
<input type="Submit">
</form>

在您的登录文件中写入以下行

$_SESSION['id'] = $row[id]; 

下面是完整的代码片段

if (!empty($row[username])) // he got it.
{
    $_SESSION[username] = $row[username];
    $_SESSION['id'] = $row[id]; 
    echo "<center>Welcome $_POST[username]! You've been successfully logged in.   <br><h2 style='color: Yellow;'>REDIRECTING.....</H2><br><img    src='http://i1261.photobucket.com/albums/ii586/jacob1899/ajax-loader-1.gif'></center>      <meta http-equiv='REFRESH' content='1;url=/index.htm'>";
    exit();
}
else // bad info.
{
    echo "<center>Error - Couldn't login user!!";
    exit();
}

发布您的用户登录代码。您必须存储来自该代码登录或注册的id，还是两者都要@GBD@GBD上面有我的登录码我仍然认为我的注册码可能更有用。。。如果您需要，请告诉我Write

$\u SESSION['id']=$row[id]就在第行之后
$\u SESSION[username]=$row[username]在您的登录文件中。然后注释掉
$\u会话['id']='9'来自您的edit.phpi，我是在评论部分给出解决方案的同一个人。如果这个答案对你有帮助，那么接受它也会对你有帮助
$_SESSION['id'] = $row[id]; 

if (!empty($row[username])) // he got it.
{
    $_SESSION[username] = $row[username];
    $_SESSION['id'] = $row[id]; 
    echo "<center>Welcome $_POST[username]! You've been successfully logged in.   <br><h2 style='color: Yellow;'>REDIRECTING.....</H2><br><img    src='http://i1261.photobucket.com/albums/ii586/jacob1899/ajax-loader-1.gif'></center>      <meta http-equiv='REFRESH' content='1;url=/index.htm'>";
    exit();
}
else // bad info.
{
    echo "<center>Error - Couldn't login user!!";
    exit();
}

//$_SESSION['id'] = '9'; from your edit.php
