PHP - Continue Unique Session After Redirect?
i'm need to retrieve a session after i've collected the data and went to PayPal (...urk...) i think i'm starting off correctly... but how the hell do i get the session name on the other side?
Code: [Select] $uuid = uniqid(); session_name = $uuid; session_start(); // do some stuff // go to PayPal // come back from PayPal ....um... now i'm lost! how do i get the $uuid here?? once i come back from PayPal... this is where i get lost. how do i load a UUID-based session if i can't get the $uuid? and if there's a better way, by all means let me know! someone said i could pass the $uuid through PayPal, but i'm not seeing how yet... TIA gang! WR! Similar TutorialsHello! Everybody in my class have their own folder on a domain, so its like: www.thedomain.no/nameofstudent. The problem we are facing is that when i log in on my site i also get logged in on all the other students sites too... (we are all using Dreamweaver CS5.5) We all have a: Welcome, USERNAME, massage on our sites. However if i first log in on my site, then visit another students site i get the massage: Welcome, (and the username i logged in with on my site!) another problem is when i try to access the shopping cart of student X's site (then i get redirected to the loging page on his site), If i then leave that tab open in chrome and open a new one, then i go to my login page in than new tab ON my site, then i log in on my site. Instead of getting redirected to MY index i get redirected to student X's shopping cart... I tried to rename the Session variable without luck. (default dreamweaver is $_Session['MM_Username']) Any Suggestions? Hope i made myself understandable Thanks I've been trying to grab the unique auto incrementing table id and put into a session variable. $name_id = mysql_insert_id(); $query = sprintf("INSERT INTO profile ( name_id, bio, ex) VALUES (LAST_INSERT_ID(),'%s','%s')", mysql_real_escape_string($_SESSION['pro']['bio']), mysql_real_escape_string($_SESSION['pro']['ex'])); $result = mysql_query($query, $db) or die(mysql_error($db)); $name_id = mysql_insert_id(); $_SESSION['name_id'] = $name_id; //this is the key line $_SESSION['logged'] = 1; header('Refresh: 5; URL=main.php'); I've echoed out the result of $_SESSION['name_id'] and it says '0'. I've tried changing the key line to $_SESSION['name_id'] = LAST_INSERT_ID(); but I get this error message: Fatal error: Call to undefined function LAST_INSERT_ID() in C:\x\xa Is my goal acheivavle or should I just set up a select query after the insert query and extract the id key? Ok so a user tries to access a part of the site that requires them to login. So they are taken to the login page. but when they login I want them transfered to the page they were going to. So i thought of something like: <a href="securepage.php" onClick="<?php echo $_SESSION['clicked_link'] = $site_root.'securepage.php'; ?>"> Click Here </a> But when I echo $_SESSION['clicked_link'] not only am i getting the url i am getting the content after. echoed it looks like: http://www.thevault.cz.cc/securepage.php">Click Here So is there a better way to do it? if not what would i need to do to remove everything after the " ? I've got a weird problem which affects only Safari browsers. Site A offers user a login page and validates the credentials by calling HTTPRequest on site B ( this call starts new session, user password is checked and session id stored in the db). If user login details are OK, site A redirects user to site B ( different domains and physical boxes). It worked well before the last Safari update (5.0.1) - when user login is being checked, server B creates session X, after the redirect, session_start() creates absolutely different session Y. All sessions are maintained by cookies only (SSL). Any ideas how to maintain the same session during the redirect? Thanks! i have a login script im using if someone landed accidentally on a page i want him to be redirected and not have access Code: [Select] <?php if (isset($session->logged_in)){ } else{header("Location: ../index.php");} ?> Hi. I am trying to create a very simple admin login page that will let only me access a number of pages. I am trying the following code for the login page: Code: [Select] <?php session_start(); // Define your username and password $username = "username"; $password = "password"; if ($_POST['txtUsername'] == $username && $_POST['txtPassword'] == $password) { $_SESSION['admin']="true"; header("location: admin.php"); } ?> ### HTML code and form for entering in username and password with action echoing it back to itself ### On the admin.php page i then try: Code: [Select] <?php if ($_SESSION['admin'] != "true") { header("location: login.php");} else { ?> ### code for the rest of the page ### I am fairly new to all this and cant understand why its remaining on the login page and not sending me to admin.php when the password and username are correct. Is this the correct way to be going about it? I envisaged simply adding the above code to the top of any page only the admin could see. Any help is much appreciated. I have four session variables, two I am valueing using $_POST elements from a previous page's form, the other two I am valueing using items retrieved from a database. Here is the code - ---------------------------------------------------- <?php session_start(); $_SESSION['UserLastName'] = strtolower(trim($_POST['txtLastName'])); $_SESSION['BadgeID'] = trim($_POST['txtBadgeID']); //get list for supervisor drop down $q1 = sprintf("select * from emps where emp_last = '".$_SESSION['UserLastName']."' and emp_badge = '".$_SESSION['BadgeID']."'"); $rs_emp_info = hitMSSQL($q1,"intra_sql","employees","xxxx","xxxx",1); $_SESSION['SSN'] = $rs_emp_info->fields("emp_ssn"); $_SESSION['CostCenter'] = $rs_emp_info->fields("emp_costcenter"); if ($_POST['rdoAction'] == 0) { header("Location: http://webapps/injury/empForm.php"); } ?> ---------------------------- When I get to the next page, empForm.php, the Last name and badge ID session vars are populated but the SSN and Cost Center session vars are not. I have tried several things including putting an exit(); after my header statement and first putting the database items into plain old $vars and then trying to populate the session vars with the value of the regular $vars, but nothing seems to work. I have a session_start() at the top of all of my scripts. Any idea why I am losing these values? (and why this box that I am typing into on this site is bouncing around so badly that I can't see what I am typing here???) I am working on getting members that are ready to make a payment after they have logged in and want to view their emails to make the payment first. How can I reprogram my session to stop them from entering the email section and make a payment first. This is my codes which work fine. Just need to know how to amend it to redirect them to payment. <?php //Start session session_start(); //Check whether the session variable SESS_MEMBER_ID is present or not if(!isset($_SESSION['SESS_ID']) || (trim($_SESSION['SESS_ID']) == '')) { header("location: access-denied.php"); exit(); } ?> Hey guys, i always get the error: Warning: Cannot modify header information - headers already sent by (output started at /home/worldw44/public_html/Newsletter/Admin/Admin.php:1) in /home/worldw44/public_html/Newsletter/Admin/Admin.php on line 6 when im tyring to run: <?php if(isset($_SESSION['adminlogin'])) { $run=yes; } else { header( 'Location: http://www.worldwidelighthouses.com/Newsletter/Admin/Log-In.php'); }?> <!DOCTYPE HTML> <html lang="en-GB"> <head> <meta charset="utf-8"> <!--Search Engine Meta Tags--> <meta name="author" content="Worldwide Lighthouses"> <meta name="keywords" content="Lighthouses,Lightships,Trinity House,Fog Signals,Fog Horns,Fresnel"> <meta name="description" content="Worldwide Lighthouses is the number 1 source of information, pictures and videos on the Subject of Lighthouses and Lightships"> <!--Stylesheets/Javascript--> <link rel="stylesheet" href="../../Page-Layout.css" media="screen and (min-width: 481px)"> <link rel="stylesheet" href="../../Mobile-Page-Layout.css" media="only screen and (max-width:480px)"> <!--Mobile Browser Support--> <meta name="viewport" content="width=320; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"> <!--IE Support--> <!--[if lt IE 9]><script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <link rel="stylesheet" href="../Page-Layout.css"><![endif]--> <meta name="application-name" content="Worldwide Lighthouses"> <meta name="msapplication-starturl" content="http://worldwidelighthouses.com/"> <meta name="msapplication-tooltip" content="Worldwide Lighthouses: Your number one source of Lighthouse Information, Videos and Pictures"> <meta name="msapplication-task" content="name=Lighthouses;action-uri=http://worldwidelighthouses.com/Lighthouses.php;icon-uri=http://worldwidelighthouses.com/IE9/Lighthouses.ico"> <meta name="msapplication-task" content="name=Lightships;action-uri=http://worldwidelighthouses.com/Lightships.php;icon-uri=http://worldwidelighthouses.com/IE9/Lightships.ico"> <meta name="msapplication-task" content="name=Fog Signals;action-uri=http://worldwidelighthouses.com/Fog-Signals.php;icon-uri=http://worldwidelighthouses.com/IE9/Fog-Signals.ico"> <meta name="msapplication-task" content="name=Glossary;action-uri=http://worldwidelighthouses.com/Glossary.php;icon-uri=http://worldwidelighthouses.com/IE9/Glossary.ico"> <title>Mailing List Administration | Worldwide Lighthouses</title> </head> <body> <header> <h1 id="WWLH">Worldwide Lighthouses</h1> <form method="get" action="http://www.worldwidelighthouses.com/Search/search.php" id="Search-Box"> <input type="search" placeholder="Search Worldwide Lighthouses" name="query" id="query" size="30" value="" autocomplete="off"> <input type="submit" value="Search"> <input type="hidden" name="search" value="1"> </form> </header> <nav> <ul id="Nav"> <li class="MenuButton" id="Index"><a href="../Index.php"><p class="Nav">Home</p></a></li> <li class="MenuButton" id="Lighthouses"><a href="../Lighthouses.php"><p class="Nav">Lighthouses</p></a></li> <li class="MenuButton" id="Lightships"><a href="../Lightships.php"><p class="Nav">Lightships</p></a></li> <li class="MenuButton" id="FogSignals"><a href="../Fog-Signals.php"><p class="Nav">Fog Signals</p></a></li> <li class="MenuButton" id="Daymarks"><a href="../Daymarks.php"><p class="Nav">Daymarks</p></a></li> <li class="MenuButton" id="Buoys"><a href="../Buoys.php"><p class="Nav">Buoys</p></a></li> <li id="MenuButtonLast"><a href="../Glossary.php"><p class="Nav">Glossary</p></a></li> </ul> </nav> <article> <h1 class="Title">Contact Admin Centre</h1> <div class="Textbox"> <div id="Social"> <a href="http://twitter.com/share" class="twitter-share-button" data-count="horizontal" data-via="WWlighthouses">Tweet</a><script type="text/javascript" src="http://platform.twitter.com/widgets.js"></script> <object id="Facebook" data="http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fworldwidelighthouses.com/&layout=button_count&show_faces=false&width=450&action=like&colorscheme=light&height=21"></object> </div> </div> </article> <footer> <ul> <li><a href="../About.php">About</a></li> <li><a href="../Contact-us.php">Contact</a></li> <li><a href="../Use-Our-Media.php">Use our media</a></li> <li><a href="../Search/search.php">Search</a></li> <li><a href="../Social-Networking.php">Social</a></li> <li><a href="#Top">Back to top</a></li> </ul> <br> <br> &#169; Worldwide Lighthouses <?php echo date("Y"); ?> </footer> </body> Cany anyone offer some suggestions as to why? Note i have no ability to change phpconfig. I have a mysql table which will store users email addresses (each is unique and is the primary field) and a timestamp. I have added another column called `'unique_code' (varchar(64), utf8_unicode_ci)`. What I would very much appreciate assistance with is; a) Generating a 5 digit alphanumeric code, ie: 5ABH6 b) Check all rows the 'unique_code' column to ensure it is unique, otherwise re-generate and check again c) Insert the uniquely generated 5 digit alphanumeric code into `'unique_code'` column, corresponding to the email address just entered. d) display the code on screen. What code must I put and where? **My current php is as follows:** Code: [Select] require "includes/connect.php"; $msg = ''; if($_POST['email']){ // Requested with AJAX: $ajax = ($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest'); try{ if(!filter_input(INPUT_POST,'email',FILTER_VALIDATE_EMAIL)){ throw new Exception('Invalid Email!'); } $mysqli->query("INSERT INTO coming_soon_emails SET email='".$mysqli->real_escape_string($_POST['email'])."'"); if($mysqli->affected_rows != 1){ throw new Exception('You are already on the notification list.'); } if($ajax){ die('{"status":1}'); } $msg = "Thank you!"; } catch (Exception $e){ if($ajax){ die(json_encode(array('error'=>$e->getMessage()))); } $msg = $e->getMessage(); } } hi i am stuck in a loop please can someone check what is miss. I wants to quit from loop and go to next title if that tile is found but cant figure out how should i go. my code: $feed_url = "http://www.myfeed.com/feed/"; $xml = simplexml_load_file($feed_url); foreach ($xml->channel->item as $item) { $ns_content = $item->children('http://purl.org/rss/1.0/modules/content/'); $title = $item->title; // opening file which contain titles already $content = file('file.txt'); foreach ($content as $aline) { if (strstr($title, $aline)) { $found = true; } } // i dont wants to print that $title which is already in file.txt so loop continue. if($found) { continue; } echo $title . "<br>" ; } Problem is with that continue statement if a title is matched from file.txt it will display me nothing, i only wants to skip that title and echo other titles. thanks for any help im building a form in php and is their away to have a submit or continue button on the same page so if ya want to fill in more it will go to the next page if not it will e-mail the info By calling function two will it break the loop?; or do i have to echo what is returned? Code: [Select] functione one() { $getids = mysql_query("SELECT * FROM table"); while($row=mysql_fetch_assoc($getids); { $this->two(); } } function two() { return 'break;'; } hello i need someone to take a look on this , General comments on the code process and how should i continue !!! [attachment deleted by admin] Help...I almost had this but I included the password field in my form now it is not working. What was happening before I had all the tested members added to the Welcome page at once. When I put in the password field it is not welcoming anyone so sessions is not operating. // Get the user session id variable into a local php variable for easier use in scripting $id = $_SESSION['id']; // Now let's initialize vars to be printed to page in the HTML section so our script does not return errors // they must be initialized in some server environments $firstname = ''; $lastname = ''; $country = ''; $email = ''; //Formulate Query //This is the best way to perform an SQL query $query = "SELECT id, firstname FROM `Members` WHERE id='$id'"; $result = mysql_query($query); //Check result //This shows the actual query sent to MySQL and the error. Useful for debugging. if(!$result){ $message = 'Invalid query:' . mysql_error() . "\n"; $message .= 'Whole query:' . $query; die($message); } //Use result //Attempting to print $result won't allow access to information in the resource //One of the mysql result functions must be used //See also mysql_result(), mysql_fetch_array(), mysql_fetch_row(), etc. while($row=mysql_fetch_assoc($result)){ echo "Welcome, {$row[firstname]}"; } //Free the resources associated with the result set mysql_free_result($result); At one point it when it was including everyone all at once it was able to view the private pages but the new update password takes me back to square one. It was showing a error message with SQL " after the WHERE clause where I had the id={$_SESSION['id']} so I just tested to see how the codes id='$id' would work and it does not have the echo Welcome, firstname. these codes are very tricky. I have spent the last few days going over Zend framework 2, and I am finding it extremely complex. Not saying it shouldn't be, but it seems to solve problems I never have come across (so to speak) .
For instance:
Routing is super complex. I usually use torophp - which is simple & gets the job done.
Dependency injection - example of problem I have never come across.
My motivations for learning zend, are -
1. To write modular reuseable code.
2. Learn advanced / modern PHP , as far as frameworks are concerned I just know codeigniter.
3. A framework with good long term support.
Is there some other framework that is easier to learn ? and that would satisfy my requirements ?
I have been programming in PHP for the last 2-3 years btw, so I know my way around
Thanks
