PHP - Update Items In Session
Hi,
i have had some help from these forums building a shopping cart system and i can add items to cart, empty cart but i need some help on how to update quantities. Here is the code i use to add items Code: [Select] $pid = $_POST['prodid']; $q = $_POST['qty']; if(array_key_exists($pid, $_SESSION['cart'])) { $_SESSION['cart'][$pid]=$_SESSION['cart'][$pid]+$q; } ELSE { $_SESSION['cart'][$pid]=$q; } Im displaying my items in a table with a text field for quantities which can be changed then click update. i see there is 2 things i need to do, first is to somehow create a loop for all the items in my table, i have no clue where to start on that, and then in that loop i have my update command. im assuming the code to update would be something like Code: [Select] $_SESSION['cart'][$pid]=$_SESSION['cart'][$pid][$qty] where $qty is the value of the text box in my table. Any help would be appreciated. Similar TutorialsWhen I remove 1 session item using this it works fine when I select more than 1 item to be removed I get unexpected results, I have checked the outputted html to see what positions get echoed into the remove check box and they are correct, so I guess the problem lies in my remove code here is the part of the form that sends the remove check box <?php for ($basket_counter=0;$basket_counter<$_SESSION['ses_basket_items'];$basket_counter++) { $price=sprintf("%01.2f",$ses_basket_price[$basket_counter]); $quantity=$ses_basket_amount[$basket_counter]; $code=$ses_basket_stockcode[$basket_counter]; $itemID=$ses_basket_id[$basket_counter]; $name=$ses_basket_name[$basket_counter]; $image=$ses_basket_image[$basket_counter]; $size=$ses_basket_size[$basket_counter]; $sizechoice=$ses_basket_sizechoice[$basket_counter]; // create array from sizes and make the option box selections if ($sizechoice!="" && (!in_array($sizechoice, array('One Size', 'one size', 'free size', 'Free Size', 'Adjustable', 'adjustable')))) { // add size trigger $sizelist="add"; //create the array $sizepick=explode(",", $sizechoice); } else { $sizepick=$sizechoice; } // adjust gst for AU customers if ($country=='AU') { $price=sprintf("%01.2f",($price*1.1)); $unit=sprintf("%01.2f",($price/$quantity)); } else { $unit=sprintf("%01.2f",($price/$quantity)); } ?> <tr> <td align='center' class='rescon' style="border-bottom:solid #330000 1px;"><input type="checkbox" name="remove[<?php echo $basket_counter; ?>]" value="<?php echo $basket_counter; ?>" /></td> and here is the part of the code that processes the removal of the items $remove = $_POST['remove']; if (isset($remove) && ($remove!='')) { foreach($remove AS $key => $remove_position){ array_splice ($ses_basket_name, $remove_position, 1); array_splice ($ses_basket_amount, $remove_position, 1); array_splice ($ses_basket_price, $remove_position, 1); array_splice ($ses_basket_stockcode, $remove_position, 1); array_splice ($ses_basket_image, $remove_position, 1); array_splice ($ses_basket_size, $remove_position, 1); array_splice ($ses_basket_sizechoice, $remove_position, 1); array_splice ($ses_basket_id, $remove_position, 1); $_SESSION['ses_basket_items']--; } } I am using a form with checkboxes named remove[$remove_position] and the positions in the form are correct for each item in the array, but when I select more than 1 item to delete they are not always the correct items only the first 1 selected. What am I doing wrong here?? I have the following session variables for each item in a cart, which gets updated each time an item is added from the catalog // Register the session variables $_SESSION['ses_basket_items']=$ses_basket_items; $_SESSION['ses_basket_name']=$ses_basket_name; $_SESSION['ses_basket_amount']=$ses_basket_amount; $_SESSION['ses_basket_price']=$ses_basket_price; $_SESSION['ses_basket_stockcode']=$ses_basket_stockcode; $_SESSION['ses_basket_image']=$ses_basket_image; $_SESSION['ses_basket_size']=$ses_basket_size; $_SESSION['ses_basket_sizechoice']=$ses_basket_sizechoice; $_SESSION['ses_basket_id']=$ses_basket_id; I have a current cart page which loops through the sessions and displays them in a form. I have a check box for each item with the name="remove[]" and the value is the itemID which is the $ses_basket_id of item in the session. I have a select box with name="size[]" and the value is the users selected size for each item in the session which is $ses_basket_size Finnally I have a quantity text box with name="quantity[]" and the value is the users quantity value selected which is $ses_basket_amount. After all the looping through the products displaying each item in a row I have an update cart submit button name="change" outside the loop. What I want to know is how do I setup to perform each of these actions for each item in the session, how do I create the foreach loops for each array to delete or modify the correct items in the session if they are modified. I have the code to perform each task but dont know how to loop it through for each item in the session affecting only the correct session items. so if I have 3 items in the session for example, and I want to change the size of item 1, remove item 2 and change item 3 for quantity 1 to quantity 3 with only the 1 form and change button for all items and actions? Hope that makes sense any help with this would be appreciated. hello all, I was hoping someone could help me figure out how to add sizes to my shopping cart. Right now the items add just fine. The site sells shirts and I'm having trouble displaying the sizes once selected and added to the cart. It will post the size selected, but if the customer tries to add another shirt the size will overwrite the last. Any help is appreciated. Heres how I add items to the cart... Code: [Select] session_start(); // Process actions $cart = $_SESSION['cart']; $action = $_GET['action']; switch ($action) { case 'empty': if($cart) { unset($cart); } break; case 'add': if ($cart) { $cart .= ','.$_GET['product_id']; } else { $cart = $_GET['product_id']; } break; The form with the size selection and add to cart button.. Code: [Select] <form action="cart.php?action=add&product_id=<?php echo $row_rs_products['product_id'] ?>" method="POST" name="addcart" id="addcart"> <table width="300" border="0"> <tr> <td><label for="sizes"></label> <select name="product_size" id="product_size" title="<?php echo $row_rs_products['product_size']; ?>"> <?php do { ?> <?php } while ($row_rs_sizes = mysql_fetch_assoc($rs_sizes)); $rows = mysql_num_rows($rs_sizes); if($rows > 0) { mysql_data_seek($rs_sizes, 0); $row_rs_sizes = mysql_fetch_assoc($rs_sizes); } ?> </select></td> <td><input type="submit" name="submit" id="submit" value="add to cart"> function displaying the cart..

My problem here is that.. i just wondering what make the session variables display its own value (not expected value).. this variable name got no similar across the whole site. i just wanna hear what are the possible causes why this happen... thanks I'm helping out a friend who owns a boarding kennel. She would like an online site where she or a client can register, add their dogs to their profile and other info. I know CSS and HTML but have very, very little experience in PHP, I figured it would be fun to give this a try and learn something new. So far I've managed to create a register and log in area, and now I'm trying to make it possible for someone to add a dog breed from a drop down list to their "page" after they've logged in. I cannot get the data to insert into that specific user's table. I'm trying to use the session id and session username as the variable, and this is where the problem comes in. If I type the userid and the username out then the data will update fine...but that's not practical. I need it to know which user is logged in and update them accordingly. Anyway, what I'm typing here makes sense in my head but I've been staring at this computer all day and it's possible I'm way out in left field, so here's the code to see for yourself. (chances are it's something totally obvious....or I have stuff in there that doesn't belong, I haven't a clue.) Thank you in advance to anyone willing to help me out!

Sorry!</p>"; exit; } ?> Thanks in advance I'm making a simple login system with MySQL and PHP (very simple, I'm just starting with PHP). The MySQL portion is done, but I need to ensure only people who are logged in can see certain content. To check if people are logged in, my website checks that they have the $_SESSION['user'] variable set. If it is set, then it lets them continue through the website, if not, it tells them to login. Is that enough security, or can people simply inject a session cookie into their browser to spoof that they are logged in? My idea was to generate a session key cookie when they login (just a random string of letters and numbers) and store that in the database, then on every page, check to make sure their session key is the same thing that's in the database. Is this necessary? It seems expensive. hi everyone. i'm wondering what the best way is to create a session variable and pass it to an iframe. i need to do something along these lines, but it doesn't seem to pass the ID. Any hints on how i should accomplish this? Code: [Select] session_start(); $_SESSION['ID']=$_GET['ID']; // id from previous page $ID=session_id(); <iframe src="iframepage.php?ID=<?php echo $ID; ?>" style="width:680px; height:200px;" noresize="noresize" frameborder="0" border="0" scrolling="Yes" allowtransparency="true" /> </iframe> what Im basically trying to do is just like a phpmyadmin function... you select rows you want to update with a checkbox and then it takes you to a page where the rows that are clicked are shown in forms so that you can view and edit info in them... and then have 1 submit button to update them all at once. Just curious how other people feel about this. I am working on an application where a lot of info is pulled from MySQL and needed on multiple pages.
Would it make more sense to...
1. Pull all data ONCE and store it in SESSION variables to use on other pages
2. Pull the data from the database on each new page that needs it
I assume the preferred method is #1, but maybe there is some downside to using SESSION variables "too much"?
Side question that's kind of related: As far as URLs, is it preferable to have data stored in them (i.e. domain.com/somepage.php?somedata=something&otherdata=thisdata) or use SESSION variables to store that data so the URLs can stay general/clean (i.e. domain.com/somepage.php)?
Both are probably loaded questions but any possible insight would be appreciated.
Thanks!

Edited by galvin, 04 November 2014 - 10:30 AM. Evening! I've been iffing and ahhing over this and well im not too sure, hence the post. Code: [Select] // Redirects if there is no session id selected and echos the error on the previous page if(!isset($_GET['get']) || ($_GET['getget'])){ header("Location: #.php?error"); } So it should simply check if get is set if it isnt then see if getget is set? If not redirect and show the error. Now ive tried it and even when get/getget is set it still redirects, probably something silly. Care to share anyone? Harry. I'm new to PHP and I was able to figure out how to populate data from my database into my text fields. I am trying to add the update information to the same php file; however, I am now receiving errors within the data I was able to populate,
Notice: Undefined variable: stmt in C:\xampp\htdocs\Cust_App\update.php on line 47 and errors with the Update statement
Notice: Undefined variable: stmtupdate in C:\xampp\htdocs\Cust_App\update.php on line 96 I had defined the customerID variable above in the code, but it isn't being captured from here. I tried setting up this query like the one which gathered the data, but I'm off by a little bit. I would like the option to be able to update all fields. Any help is appreciated. I'm trying to learn as I may get asked to update other forms in the future. (new boss asks a lot)

Hi Guys, I want my UPDATE function from the code below to only update those fields that are NOT empty - if they are empty on submit then do not update or change any values from that field. I know that sounds odd, but with my file fields, when I submit to change something else at a later date it will overwrite the photo, download1,2 & 3 values and as a result I loose my files from the mysql table. Cheers, S <?php include('config.php'); if (isset($_GET['Ter']) ) { $ter = (int) $_GET['Ter']; if (isset($_POST['submitted'])) { //Photo & Document Upload Upload $timestamp_photo = time(); $timestamp_download1 = time(); $timestamp_download2 = time(); $timestamp_download3 = time(); //This is the directory where the files will be saved //Photos $photo_target = "images/"; $photo_target = $photo_target .$timestamp_photo. basename( $_FILES['photo']['name']); //Documents $download_target = "documents/"; $download_target1 = $download_target .$timestamp_download1. basename( $_FILES['download1']['name']); $download_target2 = $download_target .$timestamp_download2. basename( $_FILES['download2']['name']); $download_target3 = $download_target .$timestamp_download3. basename( $_FILES['download3']['name']); //This gets all the other information from the form $photo = ($_FILES['photo']['name']); $download1 = ($_FILES['download1']['name']); $download2 = ($_FILES['download2']['name']); $download3 = ($_FILES['download3']['name']); //Pause Photo/Document Upload foreach($_POST AS $key => $value) { $_POST[$key] = mysql_real_escape_string($value); } $sql= "UPDATE `ter` SET `Ter` = '{$_POST['Ter']}' , `BranchName` = '{$_POST['BranchName']}' , `BranchAddress` = '{$_POST['BranchAddress']}' , `BranchTel` = '{$_POST['BranchTel']}' , `BranchEmail` = '{$_POST['BranchEmail']}' , `BranchLink` = '{$_POST['BranchLink']}' , `Theme` = '{$_POST['Theme']}' , `LocalInfo` = '{$_POST['LocalInfo']}' , `BranchInfo` = '{$_POST['BranchInfo']}' , `photo` = '$timestamp_photo{$_FILES['photo']['name']}' , `download1` = '$timestamp_download1{$_FILES['download1']['name']}' , `download1name` = '{$_POST['download1name']}' , `download2` = '$timestamp_download2{$_FILES['download2']['name']}' , `download2name` = '{$_POST['download2name']}' , `download3` = '$timestamp_download3{$_FILES['download3']['name']}' , `download3name` = '{$_POST['download3name']}' WHERE `Ter` = '$ter' "; mysql_query($sql) or die(mysql_error()); //Unpause Photo/Document Upload //Writes the photo to the server if(move_uploaded_file($_FILES['photo']['tmp_name'], $photo_target)) { echo "<br />The file ".$timestamp_photo. basename( $_FILES['photo']['name']).
