Buenas,
acabo de probar esto si funciona
Código PHP:
<?php
session_start();
if( isset($_POST['email']) )
{
//require_once 'inc/conexion.php';
$email = $_POST['email'];
$password = $_POST['password'];
//$newpassword = $_POST['newpassword'];
$conexion = mysql_connect('localhost','root','rodnopass');
mysql_select_db("test", $conexion);
if ($_POST['choose'] == 'login')
{
$query = "SELECT * FROM users WHERE email = '".$_POST['email']."' AND password = '".$_POST['password']."';";
$result =mysql_query($query) or die(mysql_error());
if (mysql_num_rows($result) > 0)
{
$_SESSION['logged'] = 1;
echo 'Usuario login';
}
else
echo 'Usuario y/o Password Incorrecto';
}
else
if($_POST['choose'] == 'signup')
{
if(isset($_POST['password']) && !empty($_POST['password']) && isset($_POST['newpassword']) && !empty($_POST['newpassword'])
&& $_POST['password'] == $_POST['newpassword'])
{
$query = "INSERT INTO users ( email, password ) VALUES ( '".$_POST['email']."', '".$_POST['newpassword']."');";
$result = mysql_query($query) or die(mysql_error());
if ($result)
echo 'Usuario Insertado';
else
echo 'Error al Insertar Usuario';
}
else
echo 'Los Password\'s deben coincidir y no puede esta vacíos.';
}
else
echo 'error inesperado';
}
else
echo 'Debe insertar el Email';
//style="display:none"
