PHP - Adding Form Variables Into Session Cart
Hi all
I have a php form as follows: <form action="basket.php?action=add&id=1&qty=1" method="post" name="buy-product"> <input name="initial_1" id="initial_1" type="text" size="8" maxlength="1" /> <input name="initial_2" id="initial_2" type="text" size="8" maxlength="1" /> <input name="initial_3" id="initial_3" type="text" size="8" maxlength="1" /> <input name="send" type="submit" class="contact-form-button" id="send" value="Submit" /> Basically I need to add the three initials into a session so that they can be shown in the shopping cart next to the product. How do I add the initials to the session and how do I output them to the shopping cart? At the start of my basket.php script I have: $cart = $_SESSION['cart']; $action = $_GET['action']; $id = $_GET['id']; $qty = $_GET['qty']; $initial_1 = $_POST['initial_1']; $initial_2 = $_POST['initial_2']; $initial_3 = $_POST['initial_3']; I now need to create a table with the cart showing item, price and initials. Cheers Pete. Similar TutorialsHey again, Still on the same project but now doing the cart page. I've been bringing my skills up to date a lot doing this project, however, having said that I now can't figure out why my cart is not adding the items to the cart, i've checked the post data and the quantity is set to 1. Would really appreciate someone having a look at it and hopefully can see what i'm missing. you can see what it should look like (well so far lol) at here in my sandbox site. thanks again. (p.s. The parts are all over the place on the page, so thought better put whole page, sorry if shouldn't have done that)

Hi, I have a feeling that this is going to be an easy miss but I've been over is a good few times and cannot see what it could be. Essentially, when I post the form in the first set of code (I've got rid of a load of unecessary html) the SESSION variables are not loaded into the second piece of code. Any ideas? Code: [Select] <?php session_start(); require ("connect.php"); $timeout = 1800; $logout_redirect_url = "login.php"; if (isset($_SESSION['start_time'])) { $elapsed_time = time() - $_SESSION['start_time']; if ($elapsed_time >= $timeout) { session_destroy(); header("Location: $logout_redirect_url"); } } $_SESSION['start_time'] = time(); ?> <div id="leftlink"> <a href="logout.php">Logout</a> </div> <table align="center" width="600px" cellpadding="0" cellspacing="0"> <tr> <td> <h2 align="center"><a href="index.php"><img src="images/logo.jpg" border="0" /></a> <br /> Emergency</h2> <hr /> </td> </tr> </table> </head> <body> <form action="post_reset.php" method="post" name"passre"> <table width="500" border="0" align="center" cellpadding="2" cellspacing="1"> <tr> <td width="230"><div align="right">E-mail Address : </div></td> <td width="40"> </td> <td width="230"><div align="left"> <input name="email" readonly="readonly" value="<?php echo ($_SESSION['email']) ; ?>" /></div></td> </tr> <tr> <td colspan="3"><div align="center"><input type="submit" name="submit" value="Submit" /></div></td> </tr> </table> </form> </body> </html> Code: [Select] <?php session_start; echo ($_SESSION['start_time']); require ("connect.php"); if (isset($_POST['submit'])){ $email = $_POST['email']; $getde = "SELECT * FROM users WHERE email = '$email'"; $getder = mysql_query($getde, $conn); $getdere = mysql_fetch_array($getder) Thanks Gareth This is a multi page registration form. I want to check the user input from form1.php with preg_match in form2.php then return the users details back into form1 with error messages(e.g $errname) so the user doesn't need to re enter the information. Neither the error messages or the session variables are shown in form1.php's form. I've echoed out the session variables found that the value makes it to form 2. But the variables are empty when it goes back to form 1. form1.php <html> <head> <title>Register</title> <style type="text/css"> td { vertical-align: top; } .errText { font-family: Arial; font-size: 10px;

I think I should buy a professional book, instead of my beginner one. I am a little experienced with PHP sessions, but not totally as I haven't got my head completely around its logic yet, as your about to see. I wonder wondering how I can go about adding a session entity from a HTML form input? I'm guessing it will be something like: $_POST['name'] => $_SESSION['delivery']['name']; Then, to echo the session entity, you would simply do something like: echo $_SESSION['delivery']['name']; ? Need help with this code, if someone can help me.. // current session id $sid = session_id(); // check if the product is already // in cart table for this session $sql = "SELECT pd_id FROM tbl_cart WHERE pd_id = $productId AND ct_session_id = '$sid'"; $result = dbQuery($sql); There is a problem with $sid = session_id();, in my code, that function always get me 0 in my php code.. do i need to set this in some other way.. Anyway, there are no registred users, i just need to set session for current user.. Like this tutorial: Code: [Select] http://www.phpwebcommerce.com/shop-add-to-cart.php What's the best way to store shopping cart information? I want things to stay in the cart for up to 2 weeks after they're added, without the need for somebody to log-in to their account to store them. Should I store the information in a database some how and then set a cookie referencing the cart_id in the db? I have am working on a shopping cart, for coupong buying. Here it only allows me to add one Item or One deal ata time into shopping cart. How can I change this code to accept more than one deal at a time before checking out. Code: [Select] { // add to cart /* $cart = unserialize(JFactory::getSession()->get('cart')); if (empty($cart)) $cart = new Cart(); */ // We only allow 1 item per cart from now one... $cart = new Cart(); $cart->addItem($deal); JFactory::getSession()->set('cart', serialize($cart)); $dealName = $deal->name; $buy4friend = $_GET['buy4friend']; $cartItemCount = $cart->getItem($dealId)->getCount(); if($buy4friend == 1) { $msg = $dealName . " :::<b> ". JText::_("DEAL_ADD_TO_CART_MESUN"); $link = JRoute::_("index.php?option=com_enmasse&controller=shopping&task=viewCart&buy4friend=1", false); JFactory::getApplication()->redirect($link, $msg); }else{ $msg = $dealName .

JText::_( "DEAL_ADD_TO_CART"); $link = JRoute::_("index.php?option=com_enmasse&controller=shopping&task=viewCart&buy4friend=0", false); JFactory::getApplication()->redirect($link, $msg); } This topic has been moved to Third Party PHP Scripts. http://www.phpfreaks.com/forums/index.php?topic=358003.0 Hi Guys I'm building a shopping cart based on the http://www.phpwebcommerce.com/ free tutorial. I'm getting stuck on adding sizes to the product options. what I need: Mens - available in Medium Large and XLarge Womens - available in Small Medium and Large Baby - available in 6, 12, 18 and 24 months I've created arrays to hold the sizing options: Code: [Select] $catAlias = (isset($_GET['a']) && $_GET['a'] != '') ? $_GET['a'] : 0; $product = getProductDetail($pdId, $catId, $catAlias); // populate the arrays $size_m = array("medium", "large", "x-large"); $size_w = array("small", "medium", "large"); $size_b = array("6 months", "12 months", "18 months", "24 months"); // create dropdown function createDropdown($arr, $frm) { echo '<select name="'.$frm.'" id="'.$frm.'"><option value="">Select one</option>'; foreach ($arr as $key => $value) { echo '<option value="'.$value.'">'.$value.'</option>'; } echo '</select>'; } and can call them into a dropdown depending on the department alias Code: [Select] <p>Choose your Size: <?php if ($catAlias == "mens-tees") { createDropdown($size_m, 'frmsize');} elseif ($catAlias == "womens-tees") { createDropdown($size_w, 'frmsize');} elseif ($catAlias == "inkababy") { createDropdown($size_b, 'frmsize');} ?> </p> The resulting HTML looks like this: Code: [Select] <p>Choose your Size: <select name="frmsize" id="frmsize"><option value="">Select one</option><option value="medium">medium</option><option value="large">large</option><option value="x-large">x-large</option></select></p> - so far so good. I'm struggling to find a way to pass the chosen size (frmsize) to the mini-cart and cart pages to store as an order. I've been Googling for days, reading through O'Reilly PHP, MYSQL book and haven't been getting anywhere. The flow is: Choose size click buy now > All detail are pass through getCartcontents function to mini-cart (shown in sidebar) and cart > details then passed through to checkout. Where do I store the chosen size variable for each t-shirt? How do i declare that this one is for product X in mens size or product X in womens size Would really appreciate some advice, I just can't get my head around the concept of where the chosen size goes and how to pass it to the cart(s). Thanks This is the code that I'm using for a shopping cart in order to update the quantity if the same product id is chosen. $cart_items is a two-dimensional session array composed of the id session array and the quantity session array. While looping through $cart_items, I create a temporary array $temp_array so that I can execute some logic on the array without changing the normal output. $temp_array is the $cart_items array without the last items which would be the $_REQUEST id and the $_REQUEST quantity. So the two $_REQUESTs are popped off with array_pop and then the remaining $_SESSIONs are compared to the $_REQUEST id with
$j = array_search($_REQUEST["element_id_$i"], $temp_array); if( $j==$temp_array[$i]) If $j is the key of the item in $temp_array, then the $_REQUEST is unset and the quantities for the item are added together.
There are two problems with this code. First of all the var_dump of the $temp_array is always an empty array but I am expecting to get an array with just the last element popped off. Secondly,
foreach($cart_items as $item) {
foreach($item["id"] as $key => $val) {
foreach($item["quantity"] as $i => $value) {
if ($key == $i){
$temp_array = $cart_items;
$array = array_pop($temp_array);
var_dump($temp_array);
if (isset($_REQUEST["element_id_$i"]) && isset($_REQUEST["quantity_$i"])&& isset($value)){
$j = array_search($_REQUEST["element_id_$i"], $temp_array);
if( $j==$temp_array[$i]) {
echo "<b>SAME PRODUCT ADDED</b>";
$value += $_REQUEST["quantity_$i"];
unset($_REQUEST["element_id_$i"]);
}}}}}}
Hi. I'm brand new to this forum, so sorry if I do something wrong... I'm someone who has thought myself to code in php to add dynamic objects to my basic static websites. I have had no formal education. This is not my first project however. I'm having problems with session variables working fine up to a point when I call a new file and then all my session variables are lost. I have tried everything, but cannot keep them alive when I get into this or any other new file. I display a form, get user data submitted, then display a next form and after the user submits this next form all the session variables are lost. Anyone have any idea what is killing my session variables? Thanks in advance. Say I have a dropdown menu consisting of user specific options. I need to be able to set a session variable depending on the option chosen & then re-access it on the following page. Can someone give me a crash course on how to utilize session variables? they recently reset my website so my php.ini file has been adjusted. One of my sites is no longer passing a session variable to the next page. I am sure its one of the settings being reset. here is the data from my phpinfo file. Anything that looks off to anyone? session Session Support enabled Registered save handlers files user sqlite Registered serializer handlers php php_binary wddx Directive Local Value Master Value session.auto_start Off Off session.bug_compat_42 On On session.bug_compat_warn On On session.cache_expire 180 180 session.cache_limiter nocache nocache session.cookie_domain no value no value session.cookie_httponly Off Off session.cookie_lifetime 0 0 session.cookie_path / / session.cookie_secure Off Off session.entropy_file no value no value session.entropy_length 0 0 session.gc_divisor 100 100 session.gc_maxlifetime 1440 1440 session.gc_probability 1 1 session.hash_bits_per_character 4 4 session.hash_function 0 0 session.name PHPSESSID PHPSESSID session.referer_check no value no value session.save_handler files files session.save_path /home/users/web/b535/ipw.plevtech/public_html/cgi-bin/tmp /home/users/web/b535/ipw.plevtech/public_html/cgi-bin/tmp session.serialize_handler php php session.use_cookies On On session.use_only_cookies Off Off session.use_trans_sid 0 0 ...anyone know anything about Internet Explorer not printing values from session variables. It works on Firefox but not on Internet Explorer. The session variable value works find on the web page but click on Print preview and it dissapears and will not print. Hi Can some steer me in the right direction. I am having issues subtotaling 2 session variables: <td>'.$_SESSION['itemqty'][$key].'*'.$_SESSION['itemprice'][$key].'</td> Can you advise if I am doing this right? Cheers Hi all I am trying to write a piece of code that takes the value from a form and checks it via an SQL table then adds the session value and the value from the SQL table into the rest of the code as a string. It is for a voucher code in a shopping basket: if(isset($_POST['voucher_code'])) { $vouchercode = $_POST['voucher_code']; $sqlvoucher_code = mysql_query(" SELECT * FROM `voucher_codes` WHERE name = ".$vouchercode.""); $getvoucher_code = mysql_fetch_array($sqlvoucher_code); $_SESSION['voucher_code'] = $_POST['voucher_code']; $voucher_code = $getvoucher_code['value']; header("Location: basket.php"); exit; } Every time I add a value into the form that I know is in the DB it returns a value of 0 even though the value in the DB is 15.95. Please help! Thanks Pete How can i keep adding value to a session??? I need to somehow keep storing more values into an array. session_start(); // store session data $_SESSION['tune_name']=$_GET['tune_name']; $_SESSION['tune']=$_GET['tune']; print_r($_SESSION); So this is what i get from the print_r(); Array ( [attach] => Array ( ) [backups-2] => true [dnb] => true [house] => true [tech-house] => true [uk-garage] => true [uk-grime] => true [uk-hip-hop] => true [uncategorized] => true [warehouse] => true [views] => Music/dnb/Gold Dust (Vocal VIP Mix)_DJ Fresh_192.mp3 [tune_name] => Music/dnb/Dj Ss - We Came To Entertain (Sub Zero Remix).mp3 [tune] => Array ( ) ) ok what i need to do is everytime i click it saves that value above but just appends another value to the array so the session can keep getting larger and larger??? Any help please. Hello! I'm a bit of a novice on PHP variables still and perhaps I'm trying to run before I can walk. I have an SQL database that I am able to successfully write to without any problems. I have also created a session variable for the user id number that I am able to retrieve on a later page. My problem is that I have hit a wall when it comes to retrieving the data from the database based upon the session variable user id. Here is my code and error: $_SESSION['ID_ASSIGNED']=$_POST[KSU_ID]; //this line takes the form data and successfully assigns it to the session variable on an earlier page echo $_SESSION['ID_ASSIGNED']; //that line works normally. Here's my problem code (the line starting with $result ). The line works fine if I input: $result = mysql_query("SELECT * FROM $usertable WHERE KSU_ID='some id number'");: <?php $result = mysql_query("SELECT * FROM $usertable WHERE KSU_ID=$_SESSION['ID_ASSIGNED']"); $row = mysql_fetch_array($result); echo "<br />Participant Number:"; echo $row['ID']; echo "<br />Name: "; echo $row['lname']; echo ", "; echo $row['fname']; echo "<br />Student Number:"; echo $row['KSU_ID']; echo "<br />Age: "; echo $row['age']; echo "<br />Gender: "; echo $row['gender']; echo "<br />Grade: "; echo $row['grade']; mysql_close($con); ?> I have created a test account in my database with a user level of -1 and i think my code might be wrong but i am hoping someone can spot where i have gone wrong as i cannot, also a similar problem with another session variable loggedIn this is what i get when i login this is on the index page.
Notice: Undefined index: loggedIn in C:\xampp\htdocs\Login\index.php on line 11 Notice: Undefined index: loggedIn in C:\xampp\htdocs\Login\index.php on line 17 You must be logged in to view this page!Index page source code:

Also if you need my login source code:

exit();
}
if (empty($password)) {
echo "You did not enter a password, Redirecting...";
echo "<meta http-equiv='refresh' content='2' URL='login.php'>";
exit();
}
//Prevent hackers from using SQL Injection to hack into Database
$username = mysqli_real_escape_string($con, $_POST['username']);
$password = mysqli_real_escape_string($con, $_POST['password']);
$result = $con->query("SELECT * FROM $tbl_name WHERE username='$username' AND password='$password'");
$row = $result->fetch_array();
$user_level = $row['user_level'];
// check to make sure query did execute. If it did not then trigger error use mysqli::error to see why it failed
if($result->num_rows > 0)
{
//Set default user
$_SESSION['loggedIn'] == 1;
$_SESSION['user_level'] == 1;
$_SESSION['username'] == trim($_POST['username']);
header("Location: index.php");
exit();
} else if($row['user_level'] == 1) {
$_SESSION['user_level'] == 1;
//Location admin
header("Location: admin.php");
exit();
} else if($row['user_level'] == -1) {
$_SESSION['user_level'] == -1;
$_SESSION['username'] == trim($_POST['username']);
//Location banned
header("Location: banned.php");
exit();
} else if($_SESSION['loggedIn'] == true) {
//Location default user home page
header("index.php");
} else {
echo "Invalid Username/Password";
}
//Kill unwanted session
} if(isset($_POST['killsession'])) {
session_destroy();
echo "<br> <br> The Session Destroyed. (Basically means you have been logged out)";
exit();
}
?>
I appreciate all help
Question about variable variables and using session variables for them. O.K. So if I have: $foo = 3; $_SESSION['bar'] = "foo"; $$_SESSION['bar'] should equal the value of $foo, however I can't get it to work. Can someone tell me what I am doing wrong..... is it formatting??? Thanks, Thomas |
