PHP编码逻辑

Question

I have some code that always is returning $aid=1 within an else/if statement. Can anyone help me figure out why this may be happening within the logic?

<?php
session_start();
require('includes/config.php'); 
if(!$user->is_logged_in()){ header('Location: login.php'); }

include_once("config.php");

if(isset($_SESSION['account_id'])) {
$aid = $_SESSION['account_id'];
} else if(isset($_POST['aid'])) {
$aid = $_POST['aid'];
} else if(isset($_GET['aid'])) {
$aid = $_GET['aid'];
} else {$aid='1';}

include_once('includes/top.php');?>

Quick background (if it helps)... This is for a login. Once a client signs in I am trying to get only their data within the database to show. I have all of the correct data being pulled, but I cannot get the logged in user to call in the correct account_id. If I were to change the last $aid=1 to $aid=2, then it would correctly pull all of account_id=2 information, but it would do it for every logged in person.

Any advice is greatly appreciated.

Thanks!

Below is the login function

<?php 
require_once('includes/config.php');
if( $user->is_logged_in() ){ header('Location: main.php'); } 

if(isset($_POST['submit'])){

    $username = $_POST['username'];
    $password = $_POST['password'];

if($user->login($username,$password)){ 
    $_SESSION['username'] = $username;
    header('Location: main.php');
    exit;

    } else {
        $error[] = 'Invalid username/password or your account has not been activated.';
    }

}
$title = 'Login';
require('layout/header.php'); 
?>

There is some html below the php that calls in the form. I can load that up if that helps too. Thanks!

Also, the account_id's are managed within the admin section. There is an associated account_id within the clients table of the database that specifies which account each user has.

If else condition page your are not post and get any data's so post and get method will not work. Then u need to make sure session is set or not. After that only u can able to find out the exact value of $aid.
