Question

My Profile php

<?php
//profile.php

require_once 'includes/global.php';

//check to see if they're logged in
if(!isset($_SESSION['logged_in'])) {
    header("Location: login.php");
}

// finding user and viewing it
$tools = new FindUser();
$user = $tools->get($_REQUEST['userID']);

?>

This is my php for viewing user profile.

http://mywebsite.com/profile.php?userID=5 its working fine in this way.

i want my code to check if user is available in database for example if i add ?userID=10 which is not present in database it gives out mysql error or even if i use http://mywebsite.com/profile.phpthen also it give error.

so now i want if user is not available in database it should give that user is not available and when we use simple http://mywebsite.com/profile.php it should give auto add it to userID=1 OR REDIRECT it to home.php

If there is other way of doing this please let me know. well im very newbie in this field

Thanks for looking my question and answering 🙂

require_once 'includes/global.php';

//check to see if they're logged in
if(!isset($_SESSION['logged_in'])) {
    header("Location: login.php");
}

$UserID = $_GET['userID'];
$CheckQuery = mysql_query("SELECT * FROM users WHERE id='$UserID'");

$CheckNumber = mysql_num_rows($CheckQuery);
if ($CheckNumber !== 1)
{
    header("Location: index.php");
}

// finding user and viewing it
$tools = new FindUser();
$user = $tools->get($_REQUEST['userID']);

You shouldn’t use MySQL As it’s depreciated,

If you really wish to use MySQL You could check at the start of the script if there is a row count for the User ID, Example:

<?
    $UserID = $_GET['UserID'];
    $UserID = mysql_real_escape_string($UserID);
    $CheckQuery = mysql_query("SELECT * FROM users WHERE userID='$UserID'");

    $CheckNumber = mysql_num_rows($CheckQuery);
    if ($CheckNumber !== 1)
    {

    // Do something If user is Not Found
    // Redirect to Another Page OR Something
    }
?>
