I have a MySQL database working now (I realized it's easier than using flat files) and I need to get user accounts working. I'm having a lot of trouble understanding how PHP sessions work. Assuming a user has logged in and is now clicking on links and browsing around, on each page load, don't I need to check the session variable to load his username, and also check that his session is current? How do I check that the session is current? None of the examples / tutorials that I'm finding online even mention how my code is to know which user the page is being served to. Does session_start() have a magic feature that makes this check unnecessary? I know I can use cookies, but I figured I would code it without since some articles seem to indicate that cookies don't have to be required to support typical user session functionality. As written here i am trying todo the php remote support. What i was wondering is in sections line $ret .= 'cd client && ..\\win\\'.filename7z ' a ' etc, why does the user use \\ instead of a single \ and whats with the &&? i have the original php file and it reads $ret .= shell_exec('cd client;' . $filename7Z . ' a '' etc Now i know the original was made for Xampp in windows but i can get it nor this guys version to work. I assume that the \\ and && are specific to windows file systems but i can figure out how. I am trying to modify it to work on my 2k8r2 server or win7(running xampp) but get dead ends in both places. My Ubuntu server is a whole diff animal. can anyone give me any guidance? original file location here <?php require_once('nusoap.php'); $soap_server = 'http://www.domain.com/api/api.cfc?wsdl'; $client = new soapclient($soap_server); $client->call() $params = array('user' => 'username@domain.com', 'password' => 'PASSWORD'); $return_string = $client->call('getKey', $params); print_r($return_string); $subId = 'XXXXXX'; $params = array('keyStr' => $keyStr, 'subId' => $subId); $return_string = $client->call('getTodaySubIDStats', $params); print_r($return_string); unset($client); ?> spits out Parse error: syntax error, unexpected T_VARIABLE in /home/site82/public_html/stats.php on line 12 Line 12 is... $params = array('user' => 'username@domain.com', I get this errr message Notice: Undefined index: user in C:\wamp\www\Login\login.php on line 25 Here is line 25: $_SESSION['user'] == $form_username ; Here is the whole page. <?php session_start(); ?> <html> <head> <title>Login</title> <?php include('logic.inc'); ?> </head> <body> <?php if (!isset($_POST['user_name']) && isset($_POST['password'])) { die("Please enter both a username and password"); } $form_username = $_POST['user_name']; $form_password = $_POST['password']; mysqlConnect(); loginvar(); if($passdb = $form_password && $userdb = $form_username) { $_SESSION['user'] == $form_username ; echo "<hr />"; echo "Login Sucssesful <br /> "; echo '<a href="/login/index.php">Return Home</a>'; } else { die("User name does not match password"); } ?> </body> </html> Hellp! Hey all, I'm having some trouble running some mysql statements through mysqli. I've tried to debug them various ways, but to no avail. This is the offending code: class DBOPS { protected $config, $mysqli; public function __construct () { $this->config = array (...snip...); $this->mysqli = new mysqli ($this->config['server'], $this->config['username'], $this->config['password'], $this->config['database']); session_start(); } public function Login ($username, $password) { $toreturn = NULL; //Problem area is from here... $encryptedpassword = hash(...snip...); print_r(array( $this->config['usertable']['username'], $username, $this->config['usertable']['password'], $encryptedpassword)); $statement = $this->mysqli->stmt_init(); $statement->prepare('SELECT * FROM users WHERE ? = ? AND ? = ?'); $statement->bind_param( 'ssss', $this->config['usertable']['username'], $username, $this->config['usertable']['password'], $encryptedpassword); $statement->execute(); print_r($statement->affected_rows); //To here. if ($statement->affected_rows == 1) { $_SESSION[$this->config['sessiondata']['username']] = $username; $_SESSION[$this->config['sessiondata']['lastactivity']] = time(); $toreturn = TRUE; } else { $toreturn = FALSE; } $statement->close(); return $toreturn; } The print_r($statement->affected_rows); statement always returns -1, which means a query error. Is there a problem with the syntax of the predefined query in $statement->prepare('SELECT * FROM users WHERE ? = ? AND ? = ?') ? I really can't seem to find the problem in this code. There are no errors returned. The output from the print_r() statements are Code: [Select] Array ( [0] => Name [1] => Trey [2] => Password [3] => ...snip... )from the first print_r and Code: [Select] -1from the second. And lastly, I know that DIY login systems are generally discouraged, but this is more of a research project. I would greatly appreciate any help with this. Thanks. I'm attempting to convert a huge project I made with mysql to PDO. I have many cases where I would use a WHILE statement to return a query array. Code: [Select] while($row= mysql_fetch_array($result)){From what I've seen so far, it looks as though I need to use a foreach statement to do the same task. Code: [Select] foreach ($dbh->query($sql) as $row){ Is that correct? I have a system that I want to change. Hi, can someone help me figure out why the logo div isn't centering?

I (think I) get that it takes an argument which in this case is a number, an checks to see if the array isset, then uses a while loop to loop through the possible values taking each value and placing it into another function which performs some task. What I'm really confused about is how the code is using unset, If I'm correct it's unsetting the incremented value which is the value that should be used in the next iteration, now I know this is not the case, but I don't understand why this is working. I have included the code in the topic and I also wrote a small piece of code to mirror this so I could play around with it in hopes of understanding the logic but it gives me a syntax error in my IDE when I try to unset the incremented value. I know this is probably something really stupid so be kind. <?php define("NUM_0", 0); define("NUM_1", 1); define("NUM_2", 2); define("NUM_3", 3); define("NUM_4", 4); function function_1($position) { static $positions = array(NUM_0, NUM_1, NUM_2, NUM_3, NUM_4,), $index = 0; if (isset($positions[$index])) { while ($position >= $index) { $current_position = $positions[$index]; unset($positions[$index++]); function_2($current_position); } } } function function_2($position) { switch ($position) { case 0: echo '$position equals 0 <br />'; break; case 1: echo '$position equals 1 <br />'; break; case 2: echo '$position equals 2 <br />'; break; case 3: echo '$position equals 3 <br />'; break; case 4: echo '$position equals 4 <br />'; break; } } function_1(NUM_4); [b] [u]output![/u] $position equals 0 $position equals 1 $position equals 2 $position equals 3 $position equals 4 [/b] function test() { static $var_1; $var_1 = 10; if (isset($var_1)) { while ($var_1 >= 0) { $var_2 = $var_1; unset ($var_1++); // syntax error on this line. echo $var_2; } } } test(); ?> Hi guys Sorry i keep asking noob questions today... I'm working on something that has a user facing image upload facility. So i'm slowly working through a class to make this as secure as possible. One of the tips online is to use the method "is_uploaded_file ( )". According to php.net - "Returns TRUE if the file named by filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried to trick the script into working on files upon which it should not be working--for instance, /etc/passwd. " I'm not one to just use things without understanding why. So how exactly could someone get a script to work on an internal file via a browse/upload facility? Let's see.... You add values to variables but you can declare them before assigning a value... Loops are great - they do things until a specific criteria is met....then I exit or break out of them. Functions are code that do specific tasks (or series of tasks) & can be called upon at any given time during a script. An array is like a....hotel with many different rooms - each room being a different value. I get GET and POST...and know how to use them between pages. Sessions can be used to pass data between pages - they help to keep track of things.... Cookies are like little signatures from your script that you can give to a users browser for any number of reasons. I guess you could say I'm starting to get it. It's only been 4 months. That being said can someone give me a brief and yet simple summary of what a PHP Class is... Hi.
I haven't done a lot of OOP. Hardly any really. I've had a go at writing a very small class that outputs a greeting depending on what time of day it is. What do the OOP experts here make of it? What do you like, what do you hate? Is there anything I could do to make it more useful?
Here is the code;
class Greeting { // the __construct didn't do what I originally wanted. Denfine the hour outside the method (I don't know why this is a good/bad idea) /* public function __construct() { $hour_of_day = date('G'); } */ public function callGreetingPhrase() { return $this->getGreetingPhrase(); } // the setter doesn't seem to have a purpose here. I tried using it so that I could pass in a value of my choosing (for testing purposes) can't get it to work though /* public function setGreetingPhrase($value) { $this->hour_of_day = $value; } */ private function getGreetingPhrase() { $hour_of_day = date('G'); if($hour_of_day < 12 ) { // if it's before 12pm $greeting_phrase = "good morning"; } elseif($hour_of_day >= 12 && $hour_of_day < 18 ) { // if it's after 12pm but before 6pm $greeting_phrase = "good afternoon"; } else { // what is left over - after 6pm until midnight $greeting_phrase = "good evening"; } return $greeting_phrase; } } $greeting = new Greeting; echo $greeting->callGreetingPhrase();It annoyed me that I could 't figure out how to use the __constructor here to store the hour. But should that have bothered me? Can someone maybe explain a bit about the setter that I tried to use setGreetingPhrase. I only put it in because I've seen other Classes with one. Could I use a setter method here for anything useful? Any feedback appreciated! I need some help understanding the below syntax (the ? and the colon are throwing me) isset($_POST['cardType']) ? $_POST['cardType'] : ''; Thanks for any help on this .. Frank Hello, After a user gets input into my Users table in my database, I'm using lastInsertId() to grab the newly created ID and then enter the newly created ID (along with some other stuff) into a separate table. Could this potentially be a problem? In other words, what happens if 2 users on 2 different computers both sign up a the same time? How will be database know which lastInsertId() to use? Here's my current code: $dbWrite->insert('users', $data); $last_id = $dbWrite -> lastInsertId(); // get the ID that was just created $data = array ('course_id' => $_POST['course_id'], 'user_id' => $last_id); $dbWrite->insert('course_enrollment', $data); // Use that new ID in a different table Perhaps there's a way to combine the steps? Thank you for your thoughts... I don't really understand what htmlentities() does and when to use it?! The manual says this... <?php $str = "A 'quote' is <b>bold</b>"; // Outputs: A 'quote' is <b>bold</b> echo htmlentities($str); // Outputs: A &#039;quote&#039; is <b>bold</b> echo htmlentities($str, ENT_QUOTES); ?> 1.)

I've been trying to understand the concept of password_hash but so far it has eluded me!
registration
<?php if(isset($_POST['submit'])){ $name = $_POST['name']; $email = $_POST['email']; $password = $_POST['password']; //$pass_hash = PassHash::hash($_POST['password']); $hash = password_hash($password, PASSWORD_BCRYPT); $stmt = $pdo->prepare("INSERT INTO hash_test(name, email, password) VALUES(:name, :email, :password)"); $stmt->execute(array( ':name' => $name, ':email' => $email, ':password' => $hash )); if ($stmt->rowCount() ==1){ echo "Registration Successful"; }else{ echo "There was a problem taking your request"; } } ?>The registration is working fine and all fields are inserted. The problem is when loggin in, its giving me an error : unknown variable which is the $hash. The verify parameter is thus: password_verify($password, $hash) I believe the $password is the users password for login, now how/when/where do assign a value to $hash? since in my db i have email(username) password. Do i need to store the hash separately on the db? Can someone please enlighten me more my login code <?php if(isset($_POST['login'])){ $password = $_POST['password']; $stmt = $pdo->prepare("SELECT email, password FROM hash_test WHERE email=:email AND password=:password"); $stmt->execute(array( ':email' => $_POST['email'], ':password' =>$password )); //if ($stmt->rowCount() ==1){ if (password_verify($password, $hash)) { /* Valid */ echo "Right"; } else { /* Invalid */ echo "wrong"; } //} } ?>THANKS Hi i'm new to the forum and i'm wondering if anyone here could help me out with the problem i'm having. the script i have uses $_SESSION['userid'] = $users['id']; and i'm not exactly sure how to read that .. any information would be helpful. thanks in advance So I have been around the net a few times reading tutorials, watching vids as I try to teach my self php. I have come across a few items that I am having trouble understanding. The first is the use of the % symbol. For example I commonly see the % used in generating random strings of characters. Here is piece of the code I used to generate a random string. What is the purpose of % in this statement. if ($alt == 1) { $rndPKID .= $consonants[(rand() % strlen($consonants))]; $alt = 0; } else { $rndPKID .= $vowels[(rand() % strlen($vowels))]; $alt = 1; } The second is the use of the & or as it is better known. The ampersand symbol. I commonly see it used when declaring a function. function newfunction($var1, &$var2){ //Do Stuff Here. } Can anyone help me understand those 2 symbols purpose and usage in php? Hi All I have a basic login system on my site. How would I go about displaying the current logged in user information from the session Id. its quite confusing..... <?php require 'Mysql.php'; class Membership { function validate_user($un, $pwd) { $mysql = New Mysql(); $ensure_credentials = $mysql->verify_Username_and_Pass($un, ($pwd)); if($ensure_credentials) { $_SESSION['status'] = 'authorized'; header("location: ../selfbuild/Controlpanel.php"); } else return "Please enter a correct username and password"; } function log_User_Out() { if(isset($_SESSION['status'])) { unset($_SESSION['status']); if(isset($_COOKIE[session_name()])) setcookie(session_name(), '', time() - 1000); session_destroy(); } } function confirm_Member() { session_start(); if($_SESSION['status'] !='authorized') header("location: login.php"); } } Just need to display the user name at the moment but am kinda not getting how its done. Do I just need <?php session_start(); echo $un |
