Tengo dos codigos que e intentado modificar viendo post del foro pero no ago funcionar:
1.php:
<?php
include ('conexion.php);
$username = $_SESSION['tusesion'];
mysql_query("SELECT * FROM registro WHERE username = '$username'");
echo '<form method="POST" action="2.php">
<table>
<tr>
<td>Nick</td><td><input type="text" name="nuevo_username" value="'.$row["nuevo_username"].'" />
</tr>
<tr>
<td>Password</td><td><input type="text" name="nuevo_password" value="'.$row["nuevo_password"].'" />
</tr>
<td>Email</td><td><input type="text" name="nuevo_email" value="'.$row["nuevo_email"].'" />
</tr>
<tr><td></td><td><input type="submit" value="Guardar Datos" />
</table>'
?>
2.php
<?
include (conexion.php);
$username = $_SESSION['tusesion'];
$nuevo_username = ($_POST['nuevo_username']);
$nuevo_password = ($_POST['nuevo_password']);
$nuevo_email = ($_POST['nuevo_email']);
mysql_query("UPDATE registro SET username = '$nuevo_username', password = '$nuevo_password', email = '$nuevo_email' WHERE username = '$username'");
echo 'Se ha modificado tu perfil.';
?>
Saludos
