PHP - Can't Destroy Cookies In Ie8
Hi guys,
I'm having a problem with destroying Cookies in IE8 (maybe other versions of IE but this is the one I'm testing on). I am checking to see if the referrer of the site is not itself, and if not, delete all cookies with the cookie domain. if ($_COOKIE['exp_last_visit'] < mktime("23", "59", "59", "12", "03", "2010")) { if (!strstr($_SERVER['HTTP_REFERER'], $_SERVER['HTTP_HOST'])) { foreach ($_COOKIE as $key => $value) { setcookie($key, $value, time()-10000, "/", ".domain.com"); } } } This works in Chrome and FF, but of course, not IE8. If anyone could shed any light on this I'd be really grateful! Similar TutorialsHey guy's i have a script i did a few months ago and now noticed that it is doing its job but keeps the old file ..so i got the image a few times but on a different angle...
how can i optimize this code to delete the old image when doing the rotation?
<?php
session_start();
include_once 'dbconnect.php';
if (!isset($_SESSION['userSession'])) {
header("Location: index.php");
}
$degrees = -270;
$path = $_GET['Folder'];
$file =$_GET['Pic'];
$fileid =$_GET['id'];
$image = $path.'/'.$file;
$imageN = $path.'/New_'.$file;
//load the image
$source = imagecreatefromjpeg($image);
//rotate the image
$rotate = imagerotate($source, $degrees, 0);
$NewImg='New_'.$file ;
//set the Content type
//header('Content-type: image/jpeg');
//display the rotated image on the browser
//imagejpeg($rotate);
imagejpeg($rotate,$imageN,100);
//free the memory
imagedestroy($source);
imagedestroy($rotate);
$sql = "UPDATE Coupon_list SET product_image_thumb = '$NewImg' WHERE id = '$fileid'";
if (mysqli_query($DBcon, $sql)) {
echo "Rotation ok";
echo('<script language="Javascript">opener.window.location.reload(false); window.close();</script>');
} else {
echo "Error Rotating: " . mysqli_error($DBcon);
}
mysqli_close($DBcon);
?>

My code below, i already imagedestroy($newimage)... but i'm not sure if i should be destroying $oldimg as well? Any thoughts? $newimg = imagecreatetruecolor($sizeA,$sizeA) or die('Problem In Creating image'); $background = imagecolorallocate($newimg, 255, 255, 255); imagefilledrectangle($newimg, 0, 0, $sizeA, $sizeA, $background); $oldimg = imagecreatefromjpeg($source)or die('Problem In opening Source Image'); imagecopyresampled($newimg,$oldimg,0,$move,0,0,$sizeA,$new_height,ImageSX($oldimg),ImageSY($oldimg)) or die('Problem In resizing'); imagejpeg($newimg,$s1DIR,90) or die('Problem In saving'); imagedestroy($newimg); hey guys im having a spot of botter unsetting, destroying a session which has been given a cookie lifetime...i know it is possible to destroy all sessions using session_destroy() but i want to destory a particials session and not all of them. here is my method if anyone can give some advice on how i could do this please...thank you
public function destroy($name = null)
{
$namespace = $this->_namespace;
$sessions = $_SESSION[$namespace];
if ($name == null)
{
foreach ($sessions as $name => $value)
{

// sessions with lifetime
ini_set('session.cookie_lifetime', 0);
ini_set('session.gc_max_lifetime', 0);

ini_set('session.gc_divisor', 1);
$session;
}
}
}
else

Hi all, My session is not destroy even after I have click 'log out' The user will only log out only when I have closed the browser. May I know what could have caused the problem? Below is my code My admin.php page Code: [Select] <?php // For logging out if (isset($_SESSION['username'])) { echo '<a href="admin_logout.php">Log Out (' . $_SESSION['username'] . ')</a>'; // Connect to the database $dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME); // Retrieve the user data from MySQL $query = "SELECT tutor_id, name FROM tutor_profile ORDER BY name ASC"; $data = mysqli_query($dbc, $query); // Loop through the array of user data, formatting it as HTML echo '<h4>Latest members:</h4>'; echo '<table>'; while ($row = mysqli_fetch_array($data)) { echo '<td><a href="viewprofile.php?tutor_id=' . $row['tutor_id'] . '">' . $row['name'] . '</a></td></tr>'; } echo '</table>'; mysqli_close($dbc); } else { echo '<a href="admin_login.php">Log In</a>'; } ?> My logout.php page Code: [Select] <?php // If the user is logged in, delete the session vars to log them out session_start(); if (isset($_SESSION['admin_id'])) { // Delete the session vars by clearing the $_SESSION array $_SESSION = array(); // Delete the session cookie by setting its expiration to an hour ago (3600) if (isset($_COOKIE[session_name()])) { setcookie(session_name(), '', time() - 3600); } // Destroy the session session_destroy(); } // Delete the user ID and username cookies by setting their expirations to an hour ago (3600) setcookie('admin_id', '', time() - 3600); setcookie('username', '', time() - 3600); // Redirect to the home page $home_url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/admin_login.php'; header('Location: ' . $home_url); ?> Currently I have a Javascript button to close a tab window which is great, but annoying problem is when the user opens up the section again all the previous session errors are there. I have tried the following, which didnt work; [ function destroy() { window.open('destroyCode.php'); } <a href='javascript:window.close()' onclick="destroy()" ><img class='close' src='images/close.jpg' alt='Close Window' /></a> ] [ <?php session_unregister("add_customer_errors"); session_unregister("add_customer_form"); session_destroy(); ?> <html> <body onload="javascript:window.close()"> </body> </html> ] Any ideas of how to do it? I have got the session being unregistered if the data is correct and saved to the database. But what is the user wants to start and then changes there mind. Hello, How do I get a user's session destroyed when he closes his browser? Thanks in advance As my title said the question, i want to destroy my session after a particular time if user is being ideal.. currently i am using this code to define my session: Code: [Select] session_start(); // Check, if username session is NOT set then this page will jump to login page if (!isset($_SESSION['myusername'])) { header('Location: admin.php'); } what would be the best way to automate/force session destroy and cookie erase i have a facebook iframe, with facebook login which gets the activation token now the user is not logged out from the login script after he logs out of facebook. any ideas how to force cookie timeout without a logout button? im playing with Code: [Select] <?php session_start(); //Global User Object Var //loggedInUser can be used globally if constructed if (isset($_SESSION['userCakeUser'])) { $obj = casttoclass('stdClass', $_SESSION['userCakeUser']); $_SESSION['userCakeUser'] = $obj; $_SESSION['start'] = time(); // taking now logged in time $_SESSION['expire'] = $_SESSION['start'] + (1 * 60) ; // ending a session in 1 minute } if(isset($_SESSION["userCakeUser"]) && is_object($_SESSION["userCakeUser"])) { $loggedInUser = $_SESSION["userCakeUser"]; } ?> I am using a WordPress theme that uses some of its own functions besides WP functions. Let me make clear from the start that when I say "Multiple Checkboxes" in the paragraphs below I am NOT talking about checkboxes that each hold a single value. I am talking about one Checkbox field that allows multiple values to be selected and puts those values into an array with one Name value and stores the output in a string in a single mysql table field. Right up front, what I need during the Edit Ad functions is the inbuilt function that will Delete the previous Array of values in any multiple checkbox when the ad is updated. Right now updating the ad works for every situation except NO values selected or for Unchecking all previously selected values in a Multiple Checkbox. If I have, for example, 4 checkboxes selected and unselect all of them before submitting the edited ad it will return the last saved array of values but not an Empty array with no checkboxes selected. This theme has a Form Builder with a Custom fields builder used by the admin to create forms for a classified ads website. According to which category of ad the Ad creation procedure will show different forms, with different fields. I had to manually create the capability to generate multiple checkboxes...so that the different multiple checkboxes when selected and updated to the mysql table might hold a variety of values in a comma-delimited array. That works fine. When the Ad is edited on its own page, (outside of the Wordpress admin dashboard) the problem is that if a user would uncheck all checkboxes in a particular multiple checkbox then the unselected state does not overwrite the previous array of values. What returns after editing is the previous selected values. I have tried jquery functions but none of them are working the way I had hoped. so one type of checkbox might have a hypothetical value like this "name="cp_checkbox_help[]" and if three options are selected then on submit the value could be--- name="cp_checkbox_help[Sunday,Monday,Tuesday]" I use implode and explode to store the array as comma separated and retrieve the array for editing or display. I guess I need to create a Null or empty value as a default that only changes when selections are made. But, since I use implode and explode to make the array "pretty" I don't know if simply specifying nothing will erase a whole array on update. Here is some of the code used to see how I get what I get-- This displays the checkboxes that I create and name and fill with different values-- case 'checkbox': ?> <?php $options = explode(',', $result->field_values); echo '<div id="checkboxes"><table width="100%" border="0" cellspacing="0" cellpadding="5"> <tr> <th colspan="2" scope="col">' . $result->field_label. '</th> </tr>'; $myvals= explode(',', $post_meta_val); foreach ($options as $option) { { ?> <tr> <td width="4%"><input style="display:inline-block; float:left;" type="<?php echo $result->field_type; ?>" name="<?php echo $result->field_name; ?>[]" class="checkbox<?php if($result->field_req) echo ' required'?>" id="<?php echo $field_label; ?>" value="<?php echo $option; ?>" <?php foreach ($myvals as $myval) { if (in_array($myval, array($option), true)) {echo 'checked="yes"';}}?>/></td> <td width="96%"style="vertical-align:top; text-indent: 7px; text-align: left;" ><?php echo $option . '</td> </tr> ' ?> <?php } } echo ' </tr> </table></div><div class="clr"></div>'; break; Following is the main part of the code that updates the Ad form-- // update the ad and return the ad id $post_id = wp_update_post($update_ad); if($post_id) { // now update all the custom fields foreach($_POST as $meta_key => $meta_value) { if (cp_str_starts_with($meta_key, 'cp_')) if (cp_str_starts_with($meta_key, 'cp_checkbox_charley')) $meta_value= implode(',', $_POST['cp_checkbox_charley']); if (cp_str_starts_with($meta_key, 'cp_checkbox_help')) $meta_value = implode(',', $_POST['cp_checkbox_help']); if (cp_str_starts_with($meta_key, 'cp_checkbox_hello')) $meta_value= implode(',', $_POST['cp_checkbox_hello']); //echo $meta_key . ' <--metakey <br/>' . $meta_value . ' <--metavalue<br/><br/>'; // for debugging update_post_meta($post_id, $meta_key, $meta_value); } $errmsg = '<div class="box-yellow"><b>' . __('Your ad has been successfully updated.','cp') . '</b> <a href="' . CP_DASHBOARD_URL . '">' . __('Return to my dashboard','cp') . '</a></div>'; } else { // the ad wasn't updated so throw an error $errmsg = '<div class="box-red"><b>' . __('There was an error trying to update your ad.','cp') . '</b></div>'; } return $errmsg; } Back on the Edit Ad page this is the Submit <p class="submit center"> <input type="button" class="btn_orange" onclick="window.location.href='<?php echo CP_DASHBOARD_URL ?>'" value="<?php _e('Cancel', 'cp')?>" /> <input type="submit" class="btn_orange" value="<?php _e('Update Ad »','cp') ?>" name="submit" /> I have a feeling what I need is just a couple of lines to detect no posted values and then... but if one checkbox array has 6 values in it and another checkbox array has only 3 values, for example, do I need to count each specific checkbox for number of values and then overwrite or will one function completely delete the previous array and its commas? I would really appreciate some expert assistance here! hello; it seems strange that php can set cookies, since php is on the serer-side, but the cookies are on the client-side ... is there something that I am missing? Okay im having a problem with cookies so if anyone can help i would be grateful. When you login you can choose how long to stay in for. For testing purposes the choices a Forever 1 Hour 1 Day Never Based on your choice i am setting the cookie expiration as follows: if ($_POST['remember_me'] == '1') { setcookie('remember', time() + 99999999999999); } elseif ($_POST['remember_me'] == '3600') { setcookie('remember', time() + 3600); } elseif ($_POST['remember_me'] == '84600') { setcookie('remember', time() + 84600); } elseif ($_POST['remember_me'] == '0') { setcookie('remember'); } echo $_COOKIE['remember']; } Then for testing I am echoing the cookie at the head of the document: echo "Cookie: " . @$_COOKIE['remember']; The problem is that when the browser is closed the cookie is gone. Only the last option "never" is set as a session cookie which means the others should stay active even when the browser is closed shouldnt they? Anything i have missed here? I'm trying to write a script that allows the user to select their personal settings for the site. They can pick the color of their background, link color, link hover color and the header color. the first file is supposed to use the defaults, blue for the links, orange for the link hover color red for the background and blue for the header. the second file is supposed to configure the cookie variables to store the values entered by the user and the third file i'm supposed to modify the internal stylesheet to utilize the values stored in the session variables. I tried to set each of the values in file two but i think i messed it up. I dont know how to modify the stylesheet to accept and change to the values of the cookies...Please help here are the files file1.php Code: [Select] <?php //Handle the form if it has been submitted: if (isset($_POST['background_color'], $_POST['link_color'], $_POST['link_hover_color'], $_POST['header_color'])){ //send the cookies: setcookie('background_color', $_POST['background_color'], time()+10000000); setcookie('link_color', $_POST['link_color'], time()+10000000); setcookie('link_hover_color', $_POST['link_hover_color'], time()+10000000); setcookie('header_color', $_POST['header_color'], time()=10000000); //Message to be printed later: $msg = '<p>Your settings have been entered!

I am trying to set a cookie: setcookie("username", $_POST['user']); And for a while it wasn't working, then it started randomly working. Now, when I try to use if(isset($_COOKIE['username'])) PHP is saying the cookie does not exist. PLEASE help! Thanks. Hi guys, I am having a sticky problem with Cookies. Basically, I've had to change the settings of my CMS which has resulted in me now having the same cookie names for the cookie domains .domain.com and www.domain.com. I know I can just clear my cookies and the problem will be sorted, but it's not feasible for me to expect users of my site to clear their cookies. So my question is this. How can I delete the cookies created using www.domain.com with PHP? Everytime I set the expiry date of the cookies, it only applies it to those on .domain.com. Any help would be gratefully appreciated!! The code below is the only part of my script failing and I have no clue why. I even tried setting the TestCookie for 352 days. What boggles my mind is that this code used to work and is now failing. Has something changed? $value = "wtf"; setcookie("TestCookie",$value, time()+3600*24); setcookie("user", $name1, time()+14400); setcookie("userid", $uid1, time()+14400); setcookie("coid", $coid1, time()+14400); setcookie("login", "yes", time()+14400); setcookie("status", $status1, time()+14400); Hello all, I hope someone can shed some light/point me in the right direction. I have a site that allows you to search for a customer then view and change their detail. page 1 has a search box for name entry. page 2 displays all the matches retrieved from a db table that match. The user selects which customer is the correct 1 and sets a cookie containing the selected customers unique id. page 3 allows changing of the customers details. now the problem I have: If a user navigates to page 3 and has a customers details on page for viewing all is well. If they open a new tab (leaving page 3 open on first tab) and go to page 1, search for another customer, page 2 select another customer (which overwrites cookie) then to page 3. They now have two tabs open on page 3 both displaying different customer details. If they return to the first tab and change some detail, when they save it actually updates the users details that corrispond to the second tab. I know this is because the cookie has been changed that holds the unique id that is required for the update query. How can I prevent this? I've looked at sessions but it would seem the same issue would excist. Am I wrong? Many Thanks I hope I made sense. This is prob a stupid question.. but i've always wondered..
When deleting a cookie why do we use
why do we use:
setcookie($name, '', time() - 3600, "/", "", 0);
when this works just fine:
setcookie($name, '', 0, "/", "", 0);
isn't the time() just a waste of space?
I ask this because everywhere i look i see:
setcookie($name, '', time() -3600 , "/", "", 0);
i was trying to make a new login script and wanted to make point system which i can add points manually to member so i made a new column and named it userpoint i tried many many codes First i used
$_SESSION['userName'] = $username; echo "Welcome ".$_SESSION['userName']."!"; $_SESSION['userpoint'] = $userpoint; echo "you got".$_SESSION['userpoint']."!";the page showed username but didn`t show the points ! i tried then i figured out cookies
if(isset($_COOKIE['ID_my_site']))
{
setcookie( "userpoint");
$username = $_COOKIE['ID_my_site'];
$userpoint = $_COOKIE['ID_my_site'];
$pass = $_COOKIE['Key_my_site'];
$check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error());
while($info = mysql_fetch_array( $check))
{
this time the page shows both of usernames without mentioning the points ! i changed
$userpoint = $_COOKIE['ID_my_site'];to $userpoint = $_COOKIE['Key_my_site']; and it showed the hashed password i want to set a new $_COOKIE so i can get members point to member area is that possible ? the script is still missing secure and salt and the security stuff i`ll add them later i just want to know if is that possible Edited by Ahmedamer, 03 September 2014 - 09:39 PM. Hey Everyone, I just have a quick question. I have a page that has set a cookie called email_success with the value "yes". I now need some code so that when the user goes to a download page, it checks for the cookie and if there is no cookie it redirects to another page. But if there is the cookie it displays the download page. I tried i few things but didn't work. Can anyone help me please!! Thanks George |
