PHP - I Don't Understand How Array_pop Is Supposed To Work On A Session 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. Similar TutorialsHi everyone, It's been awhile since I've coded in PHP and I can't figure out whats wrong with my code... I have a simple function to grab a field from my database and return it. I can make it work without the function, but when I implement it as a function, it breaks - no error, just a blank page. This works fine: $page = "page_about"; $sql = "SELECT body FROM " . $page . " WHERE id=1"; $result = @mysql_query($sql,$connection) or die(mysql_error()); $row = mysql_fetch_array($result); $display = $row[0]; But this does not: function grabBody($page) { $sql = "SELECT body FROM " . $page . " WHERE id=1"; $result = @mysql_query($sql,$connection) or die(mysql_error()); $row = mysql_fetch_array($result); return $row[0]; } $display = grabBody("page_about"); If anyone has any idea whats wrong, please let me know!! Thank you, - Jeff Miller Hello, I've been stuck on this code for nearly 3 days and i still am not able to understand this too well. The PHP manual says "Unless the array is referenced, foreach operates on a copy of the specified array and not the array itself. foreach has some side effects on the array pointer. Don't rely on the array pointer during or after the foreach without resetting it." Right , so from what i understand from that,if i want to modify an array inside a foreach , i need to reference the array. This example was given in the PHP manual to demonstrate this reference requirement <?php $arr = array(1, 2, 3, 4); foreach ($arr as &$value) { $value = $value * 2; } // $arr is now array(2, 4, 6, 8) unset($value); // break the reference with the last element ?> But, when i try this code : <?php $array = array('Ibanez'); foreach ($array as $guitar) { $array['guitar'] = $array[0]; unset($array[0]); $array['guitar'] = 'Gibson'; } print_r($array); ?> The output of the array outside the foreach shows the changed array and not the original anymore. So doesn't this mean that the foreach CAN indeed operate on the array itself without the array being referenced? The reason i'm stuck with this code is that i'm trying to use another slightly bigger array which needs to have its keys modified within the foreach statement, but the changes refuse to leave the foreach loop. But when i tested this small piece of code above, changes are indeed getting reflected without any reference. I'm really confused now about how this works. Help is greatly appreciated is it possible to calculate sum of the element in the array_pop . i have to get sum of 3 maximum subject with grade from student .

I'm curious, is there any reason to use array_pop($value) at all when you can explode(' ', $value, -1) ??? Besides being php version < version 5.1.0 compatible of course. Hi, <?php session_start(); if(isset($_SESSION['views'])) $_SESSION['views'] = $_SESSION['views']+ 1; else $_SESSION['views'] = 1; echo "views = ". $_SESSION['views']; session_destroy(); ?> above code asically shows howmany times user refresh the page. is it possible to return counting to 1 after user refresh page 8 times. for example : User comes for the first time. Script gives 1 as output after user refresh the page. Script gives 2 as output it goes so on. i want code to return to 1 after it been refresh 8 times. how can i do that. In Firefox and Google Crome my code works correct, but in IE it doesnt. The problem is that before or after loading a page in IE, $_SESSION is unsetted. If i set $_SESSION['online'] = 1, then after reloading the page then print_r($_SESSION) outputs nothing. Hello all, I have an error handler that I need to append messages to (First name not right, Last name not right, etc) I'm using a session array to handle all error messages titled GORB. How come this code won't work? $_SESSION['GORB']['message'][] = "First name wrong"; $_SESSION['GORB']['message'][] = "Last name wrong"; How can I get it to work? I already have the handler output written and functioning fine, I just need to get it to loop over an array of errors instead of just one. I have a site with a members area that uses sessions. I migrated my DB from MySQL 4 to 5. Now my login page does not work. Please help.

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. 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, $pro2['shipping2']); }
10.?>
11.<?php
12.$maxqty=0;
13.foreach ($_SESSION['products'] as $quant) {
14.$maxqty = max($maxqty, $quant['qty']); }
15.$shi1 = $_SESSION["products"][0]["shipping1"];
16.$shi2 = $_SESSION["products"][0]["shipping2"];
17.?>

Ed 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'); if(!isset($_POST['email']) && !isset($_POST['password'])) { ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "BLOCKED URL"> <html> <head> This is a test of my patience</head> <meta http-equov="Content-Type" content="text/html; charset=iso-8859-1"/> </head> <body> <form method="post" action="<?=$_SERVER['PHP_SELF']?>"> Email: <input type="text" name="email" size="8" /> password:<input type="password" name="password" size="8" /> <input type ="submit" name ="submit" value ="submit" /> </form> </body> </html> <? exit; } else { $umail = $_SESSION['umail'] = $_POST['email']; $password = $_SESSION['password'] = $_POST['password']; dbConnect("web2"); $sql ="SELECT * FROM `user` WHERE email ='$umail'"; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); if(!$result) error('Contact DB admin'); if($result='') error('not in db'); if($_SESSION['umail'] != $row['email'] && $_SESSION['password'] != $row['password']) error('Wrong email or password'); } if(!isset($_POST['pwd1']) && !isset($_POST['pwd2'])) { ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "BLOCKED URL"> <html> <head> This is a test of my patience</head> <meta http-equov="Content-Type" content="text/html; charset=iso-8859-1"/> </head> <body> <form method="post" action="<?=$_SERVER['PHP_SELF']?>"> password: <input type="text" name="pwd1" size="8" /> password confirmation:<input type="password" name="pwd2" size="8" /> <input type ="submit" name ="submit" value ="submit" /> </form> </body> </html> <? } else { $pwd1 = $_SESSION['pwd1'] = $_POST['pwd1']; $pwd2 = $_SESSION['pwd2'] = $_POST['pwd2']; if($_SESSiON['pwd1'] == $_SESSION['pwd2']) { dbConnect("web2"); mysql_query("UPDATE user SET password ='$pwd1' WHERE email ='$umail'"); $sql="SELECT * FROM 'user' WHERE email='$umail'"; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); if($_SESSION['pwd1'] != $row['password']) { ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "(BLOCKED URl"> <html> <head> This is a test of my patience</head> <meta http-equov="Content-Type" content="text/html; charset=iso-8859-1"/> </head> <body> <form method="post" action="<?=$_SERVER['PHP_SELF']?>"> password: <input type="text" name="pwd1" size="8" /> password confirmation:<input type="password" name="pwd2" size="8" /> <input type ="submit" name ="submit" value ="submit" /> </form> </body> </html> <? } else { error(' the man'); session_unset(); session_destroy(); } } } ?> Hi Everyone, I'm building a custom shopping cart. I'm having trouble getting my code to work on a production server that is running PHP version 5.2.17. My test machine is running version 5.3.0 and the code works just fine. I do not have the ability to upgrade the version of PHP on the production machine. Here is part of my code. If we can fix this, I can fix the other switch cases: //this code adds the item to the cart and creates an array and session variable for the cart. The array is multidimensional (item id1 => quantity, item id2 => quantity, item id3 => quantity and so on...). if (isset($_GET["action"])) { $action = $_GET["action"]; $id = $_GET["id"] ; $q = $_GET["quantity"]; $cart = array(); switch ($action) { case "add": if ($_SESSION["cart"]) { $cart = $_SESSION["cart"]; if (array_key_exists($id,$cart)) { $cart[$id] = $cart[$id] + $q; } else { $cart[$id] = $q; } } else { $cart[$id] = $q; } $_SESSION["cart"] = $cart; break; } } //this code displays the cart array if ($_SESSION["cart"]) { $cart = $_SESSION["cart"]; foreach($cart as $key => $value) { $runQ1 = mysql_query("SELECT * FROM products WHERE id='$key'") or die(mysql_error()); $results = mysql_fetch_array($runQ1); print "<table><tr><td>$results[1]</td><td>$results[2]</td><td>$results[3]</td><td>$results[4]</td></tr></table>"; } } else { print "<table><tr><td>There are no items in your shopping cart.</td></tr></table>"; } The cart session variable is being set but it is only holding one item at a time. If I add a second item to the cart, the 1st item disappears and only the second one is present in the session variable and the table. I'm not sure if it is a session problem or an array problem. Please help before I lose all of my hair! I don't understand why this code works on 5.3.0 and not 5.2.17... Thanks in advance! -Isaac 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 |
