PHP - Array Or Session Problem In Php Version 5.2.17

how do i set a session array?

e.g. set session with variable $value = 13.

then set the next $value = 15 .


= 13 and [1]=15

how do i set this session. up? so it keeps on updating the array

why is it that i have to click add to cart 2 time inorder for the eventname and eventinfo to show up
if i click one time it add to the cart but it shows nothing

Code: [Select]
<?php 

//if user attempts to add something to the cart
if (isset($_POST['tid'])) {
    $tid = $_POST['tid'];
    $howmany = $_POST['howMany'];
$wasFound = false;
$i = 0;
// If the cart session variable is not set or cart array is empty
if (!isset($_SESSION["cart"]) || count($_SESSION["cart"]) < 1) { 
    // RUN IF THE CART IS EMPTY OR NOT SET
$_SESSION["cart"] = array(1 => array("item_id" => $pid, "quantity" => $howmany));
} else {
// RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
foreach ($_SESSION["cart"] as $each_item) { 
      $i++;
      while (list($key, $value) = each($each_item)) {
  if ($key == "item_id" && $value == $tid) {
  //there will recive a message
  
  $msg = "Item is already in the cart";
  $wasFound = true;
  } // close if condition
      } // close while loop
       } // close foreach loop
   if ($wasFound == false) {
   array_push($_SESSION["cart"], array("item_id" => $tid, "quantity" => $howmany));
   }
}
header("location: cart.php"); 
    exit();
}
?>

<?php 
//render the cart for the user to view on the page
$cartOutput = "";
$cartTotal = "";
$product_id_array = '';
if (!isset($_SESSION["cart"]) || count($_SESSION["cart"]) < 1) {
    $cartOutput = "<h2 align='center'>Your shopping cart is empty</h2>";
} else {
// Start the For Each loop
$i = 0; 
    foreach ($_SESSION["cart"] as $each_item) { 
$item_id = $each_item['item_id'];
$sql = mysql_query("SELECT * FROM events WHERE id='$item_id' LIMIT 1");
while ($row = mysql_fetch_array($sql)) {
$eventname = $row["eventname"];
$eventinfo = $row["eventinfo"];
$studentsprice = $row["studentsprice"];
}

//adding the price of the tickets 
//getting the total
$totalprice = $studentsprice * $howmany;
setlocale(LC_MONETARY, "en_US");

//this will amke it so it looks like real money
$totalprice = money_format("%10.2n", $totalprice );

$cartOutput = "";

//this is the table the will replace the table row below
//this is in order

Hello everyone and thanks in advance for the help. I am working on a permission system for a site I am creating that will be used to restrict access to various areas of the site. I have a table with all the permission that is linked to a group that the user is a member of. I then use a query to get a list of the permission ids the user is part of and put those into the session array. I used a basic login script I found online I planned on modifying to add my own features and to make more secure.

Originally it had just a member id and member name variable in the session array saved in the login script which are both working fine after login. I am using a dynamic variable to set one session variable for each permission with the id being the changing part in the variable name. The problem I found is that the new variables are not being set. When i removed the redirect from my login script so I could check the problem I found that the temp variable, which is also set before it saves to the session array, is blank as well. If I hit refresh on my browser the new variables become set and all is well.

I was talking to nvee in irc chat who said I need to make a function on the page I am redirected to that checks if the variable exists. I looked through the original code of the login script I am using and found that this seems to be how they did it as well so I added an if statement to my index page to check if the variable has a value with and without using if isset. In both cases the new variable is still not getting set. He also gave me some pointers to help make my login checks more secure but the main thing IM concerned with right now is to make my new permission variables accessible to the session. My login script is available in my pastebin.

Hello Everybody, i have shopping-cart with session_product. i add arrays per button to the session.   i want get the shipping1 and shipping2 fields from the array where the field qty great is or equal to 2 >= 2. i did this manualy in my example to get shi1 and shi2 lines 15 and 16. how can i get shipping1 and shipping2 automaticly?   thank you very much for your help.   here is my code

01.<?php
02.$maxshipping1=0;
03.foreach ($_SESSION['products'] as $pro1) {
04.$maxshipping1 = max($maxshipping1, $pro1['shipping1']); }
05.?>
06.<?php
07.$maxshipping2=0;
08.foreach ($_SESSION['products'] as $pro2) {
09.$maxshipping2 = max($maxshipping2, $pro2['shipping2']); }
10.?>

Hi All,

I'm running trying to add key and values to an array on multiple pages, but it seems to override the array each time I add variables on the next page, even though the keys are different.

Each page has something like this:


Code: [Select]
<label class="yes"><input type="radio" name="form_field[<?php echo "number".$f1; ?>]" value="0" > Yes</label>
<label class="no"><input type="radio" checked="checked" name="form_field[<?php echo "number".$f1; ?>]" value="1" > No</label>
<label class="unsure"><input type="radio" name="form_field[<?php echo "number".$f1; ?>]" value="2" > Unsure</label>
I then collect it as well as other page variables with:

Code: [Select]
session_start();

foreach($_POST as $name => $value) {
$_SESSION[$name] = $value;
}
on all following pages. But rather than adding to the array it writes over it each time.

Any ideas on what's going wrong here. Should the array simply be able to continue to collect the keys or do I need to do something else?

Thanks.

Hi Guys,

How can I send a session array through the URL and then use the values on the other page to create an SQL query?

Any Ideas?

Thanks in advance.

Hi Guys,

I am having a small problem with an array.

I want to push information from a form into an array.

However each time I do it it just replaces the last entry in the array with the information in stead of adding a new value to the array.

Code: [Select]

<?php

// if generate is pressed
if(isset($_POST['generate'])){

// get values from form
$name = htmlspecialchars($_REQUEST['add']);
array_push($stack, $name);

print_r($stack);
}
?>


Can anybody help?

Thanks

Ed

I have created a session array on one page and stored some values as

$_SESSION['users'] = array(
  "id"      => $row['id'],
  "fname"   => $row['ufname'],
  "lname"   => $row['ulname']
);

and then on another page I have some more values for the same session array

  "boss"      => $row['bossid'],
  "tasks"     => $row['tasks'],
  "timeframe" => $row['tframe']

I want to add these values into session array both keys and values.

is there any way of doing this? Please help

I am trying to create a website that after you receive an email you have to use the email address and password to confirm account. Then the next page allows you to change your password. I want to save the users email from the first page and use it in the SQL statement in the second page to locate the user in the DB and update the data.

There must be some problem with the way I have my code logically set up. It will make it to the 2nd step but then it will go back to the main email confirmation page.

<?php
include('common.php');
include('db.php');

session_start();
session_register('umail');
session_register('password');
session_register('pwd1');
session_register('pwd2');

Hi everyone,

I am very new to PHP and trying to learn so please bear with me.  I have a simple form which passes fields to a PHP script:

<form method="post" action="cartaction.php">
               <p>
                  <input type="submit" name="submit" value="Buy" />
                  <input type="hidden" name="cartaction" value="add" />
                  <input type="hidden" name="item" value="steelcasserole" />
               </p>
            </form>


I am trying to produce a shopping cart type page which will display the item(s) purchased.  The problem is I have more than one submit button on the page for different products but with the same fields.

I have tried to create the cartaction.php script to save the information from the form in a session variable which will allow me to output the item(s) purchased into this page prior to sending everything to a checkout page.  I can get the information to appear for a single item but the problem is I want to output the details for each product added to the cart.  At the moment, when I go back to the products page and try to add a new item to the shopping cart it just replaces the previous item that was there rather than retaining it and adding a new item underneath.

I realise its probably really obvious but I am really new to this and getting myself confused!  Any help on how to add an item then be able to go back to the products page (with the submit buttons for each product) and add a new item underneath the existing item in the shopping cart would be much appreciated!  The code I have so far is:

$submit = $_POST["submit"];
 
//If form is submitted, call the function and save all data into the array $_SESSION['form']
if($submit = "Buy"){setSessionVars();}
 
function setSessionVars() {
 
    foreach($_POST as $fieldname => $fieldvalue) {
        $_SESSION['form'][$fieldname] = $fieldvalue;
      
        } 
                                          
          echo "<table> <tr> <td>" .'<img src="images/'.$_SESSION['form']['item'].'.jpg"' . "<td/> <td>"
          . $_SESSION['form']['item'] . "</td> <td>" . '<input type="text(30)" name="value" value="1" />
                  <input type="submit" name="puchasednum" value="Update This One Item" />' . "</td> </tr> </table>";
      
};
?>


I have the session_start() function at the very top of every page.   I have also attached the entire files for the two pages I talk about above.   Thanks

Graham

When 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??

When I use the following code, it doesn't print out "test" until after I refresh the page.

unset($_SESSION["product"]);

if ( !empty($_SESSION["product"]) && ($_SESSION["product"] != NULL)) {
echo "test";
}

When I use:

var_dump($_SESSION["product"]);

It shows:

array(0) { } 

I'm wondering it that's the problem. That it's array(0) when it should be array().

I want to use array_pop to remove the last item added to the SESSION array. So it would remove the REQUEST item. The problem is that nothing is left in the session array because I pop off the last item each time that the form is submitted. Maybe I need to use array_push to push the popped items back on to the SESSION array after the logic has been applied. I don't understand how array_pop is supposed to work on a SESSION array. Can anyone explain to me what behaviour to expect? I expected to get a SESSION array with the REQUEST item removed but I thought that I would still have all of my SESSION items.
 

Hi,
I"m trying to make an external link to a web page. Them problem is that when my user clicks on the link they are taken to the destination web page, but they see an error "Your session has expired". At that point, they must either refresh the browser or exit out and click again in order to see the page.
My question is, how can I go around this problem in my code? If at all possible, I like to be able to add something to the URL so that this does not happen. Any help or guidance is appreciated.

Hello Everyone!

I have 2 problems with sessions that I'd like some assistance with.
1. The session often ends after clicking any link after logging in. (sometimes it remains alive, and in those cases it stays alive until browser is closed.)
2. The function that should start a session if a cookie is found (and correct) is not working, so if the browser is closed and re-opened the session won't start the session.

I'll include the code that I think is relevant. The odd part is that these problems occur in every browser, I have tried multiple tutorials (so different scripts) to creating a login form but somehow the same result appears every time.

function login($username, $password, $remember = false) 
{


    $sql = mysql_query("SELECT * FROM users WHERE password = '" . md5($password) . "' AND username = '" . $username . "' LIMIT 1");

            {
                setcookie("auth_key", "", time() - 3600);
            }
        }
 
}

<?php 
session_start();
include("connect.php");
include("functions.php");
include("actions.php");

initiate();
 ?>
