PHP - Cookie Probloms?
I'm not really sure if this is a cookie problem but that's all I could think of. I have a web site that users have to log into. I have seen that when I log out of my account and log into my test account my main user name will still show on the welcome page unless I let the computer sit for a bit or if I clear recent history. This happens in all the main browsers. I have also started having a problem where if I update something in my database it shows up in MySQL right away but can take a while to show up on the web page unless i clear the history. Not sure what code to post to give you an idea so if you want to see something let me know and I will put it up.
Thank you Similar Tutorialsi want to store the nickname of the user as a cookie.. somthing like set cookie name=nickname,value=smarty,expires after 1 week i know cookies are stored against domain names. what happens when another person logs in the same computer, with different login, and his nickname is diff how does the cookie get handled, and how does the right nickname flash against the right persons login id... if a user clicks ?hide=1 or ?hide=2 it does Code: [Select] if (isset($_GET['hide'])){ $id = intval($_GET['hide']); setcookie('hide', ''.$id.'',time()+32000000); header('Location: index.php'); exit; } How do I make it so if they click ?hide=1 it ad's 1, but what if they do ?hide=2 also? it would need to be 1,2 not just 2. Hi, I was trying to use setcookie on my website but when I try to use, it wasn't setting anything and then I tried to make sure if it's setting something, I added Code: [Select] echo $_COOKIE;But it shows Array (just the word) instead of tblogvalue. This is the code I'm using; Code: [Select] $Month = 2592000 + time(); setcookie(tblog, tblogvalue, $Month); echo $_COOKIE; Ok I have my login form and previously I was using $_SESSION untill I learned this removes data when browser is closed. Someone said to me to use cookies but I have no clue where to begin on setting a cookie or reading information from it. Can anyone point me to a tutorial on cookies? I have part of my script that I have used many times in many diffrent applications that works just fine. But in this use it refuses to set the cookie or do anything besides the redirect for that matter. // if login is ok then we add a cookie $ip = $_SERVER['REMOTE_ADDR']; $datem = date("j F Y, g:i a"); mysql_query("UPDATE YBK_Login SET date = '$datem' AND ip = '$ip' WHERE ID = '{{$info['ID']}'")or die(mysql_error()); $_POST['username'] = stripslashes($_POST['username']); $hour = time() + 3600; setcookie('ID_WatsonN', $_POST['username'], 0); setcookie('Key_WatsonN', $_POST['pass'], 0); setcookie('UID_WatsonN', $info['ID'], 0); setcookie('LOGIN', $info['ID'], time()+3); //then redirect them to the members area Header("Location: dashboard.php"); I have a question about cookies I want the cookie to work on all the paths / folders / directorys located in a root path. So say like.. http://www.site.com/members/login.php is the folder which sets the cookie, then this cookie will also work on like.. http://www.site.com/bla/boo/works.php I'm trying to do: setcookie(Data1, 'valueofthecookie', '/', '.site.com', 1); But its not working... Hey PHPFreaks! I have a problem with my login script, because when i login it sets a cookie and it all works. But when i got redirected and refresh the page, my script turns an error which says i'm not logged in? how come? This is what finds the cookie and redirects me Code: [Select] if(!isset($_SESSION['auth']) && !isset($_COOKIE['authcookie'])) { $_SESSION['ERROR'] = 7; header('location: index.php?login'); } Hi all, I'm struggling with a program I'm trying to write with cookies, so any help would be very much appreciated!! What I'm wanting to do is when someone visits my site, I want to display content until the end of the day, and once the days up it disappears forever/until the cookies are deleted. Could someone help me with this? Thanks lots in advance, Jake how can i set cookie like a*dm*n@**t*r*c**.*c** ?? Code: [Select] $cookkiee = $islem_1['mail'] ; $sayisi = strlen($cookkiee)-1 ; $cok = $islem_1['mail'] ; for($i=0;$i<=$sayisi;$i++) { $sifr = rand(0,2); if($sifr ==0) { $cok[$i]= '*'; } $dizik = $cok[$i]; setrawcookie("kayip",$dizik,time()+(60*30),"/"); $_COOKIE['kayip'] = $dizik; echo $dizi // etc . a*dm*n@**t*r*c**.*c** } echo $_COOKIE['kayip']; // etc. just one char being like random a My code here Code: [Select] setcookie('hide_div', $_COOKIE['hide_div'].','.$_GET['hide'],time()+32000000); When I set it, it works wonderful, but then when I see view it in my cookie it shows this code between my $_GET['hide'] values Code: [Select] %2C how do I clean it up and just make it show my " , "? Thank you Hello A few days back I searched for a (very) easy php login script, basicly just to show hidden content that's not for everyone. This is the script I found (and it works): <?php $username = "Username"; $password = "Password"; $randomword = "one"; if (isset($_COOKIE['MyLoginPage'])) { if ($_COOKIE['MyLoginPage'] == md5($password.$randomword)) { ?> <?php include 'projecten_.php'; $name = "0"; ?> <?php exit; } else { echo "<p>Bad cookie. Clear please clear them out and try to login again.</p>"; exit; } } if (isset($_GET['p']) && $_GET['p'] == "login") { if ($_POST['name'] != $username) { echo "<p>Sorry, that username does not match. Use your browser back button to go back and try again.</p>"; exit; } else if ($_POST['pass'] != $password) { echo "<p>Sorry, that password does not match. Use your browser back button to go back and try again.</p>"; exit; } else if ($_POST['name'] == $username && $_POST['pass'] == $password) { setcookie('MyLoginPage', md5($_POST['pass'].$randomword)); header("Location: $_SERVER[PHP_SELF]"); } else { echo "<p>Sorry, you could not be logged in at this time. Refresh the page and try again.</p>"; } } ?> <body style="background:url(images/repeat.gif) repeat-x #0a0a09; height:106px; margin:0px; padding:0px; text-align: center;"> <div style="margin-left: auto; margin-right: auto; position: relative; top: 120px; width: 250px; text-align: left; line-height: 28px;"> <img src="images/zenze.png" alt="Zenze" style="position: absolute; top: -100px; left: -375px;" /> <h5 style=" font-weight: none; font-size: 18px; font-family: verdana; margin: 0px; margin-bottom: 20px; color: #96ff00">Login</h5> <form action="<?php echo $_SERVER['PHP_SELF']; ?>?p=login" method="post"> <label><input type="text" name="name" id="name" /><span style="color: #999999; font-size: 12px; font-family:verdana"> Name</span></label><br /> <label><input type="password" name="pass" id="pass" /><span style="color: #999999; font-size: 12px; font-family:verdana"> Password</span></label><br /> <input type="submit" id="submit" value="Login" style="margin-top: 10px;" /></form> </div> </body> The only problem is, there is no log out fuction. I see this script works with cookies and I gave it a try, and I ended up with nothing but errors. Does anyone one has an idea to how a logout script would look like for this script? Thanks in advance, Crow test.php Code: [Select] <?php setcookie("test", 'tester', time()+3600*24*30 , "/", ".mystagingsite1.com"); header('Location: test2.php'); ?> test2.php Code: [Select] <?php echo '<pre>'; print_r($_COOKIE); echo '</pre>'; ?> This does not work. It's not setting the cookie at all. Is there something I am doing wrong here? What I want is to let visitors select a county they want to search in. And when the choice is made - all ads, news, info that is shown is from the chosen county. What I'm trying to say here, is that when a location is set, visitors don't need to set the location again. But they can change it all the time. I belive this is done by setting a cookie with PHP. But don't know how. Can anyone point me in the right direction? Hey guys I'm pretty new to both PHP and Javascript. I think my problem is a PHP one, not a Javascript one. But it involves both. I'm trying to delete a cookie by clicking a link. I call the javascript function like so: if (isset($_COOKIE["active"])) { echo "<a href='addpost.php'>Add Post</a> <a href onClick='eraseCookie()'>Log Out</a>"; } And the function looks like this: Code: [Select] function eraseCookie() { <?php setcookie(active, 0, time()-3600); echo "It works"; ?> } The function doesn't delete the cookie and doesn't echo "It works". Like I said this could be a Javascript error, not a PHP one, but I have to start somewhere. Can someone tell me what I'm doing wrong? Hi, I'm trying to set cookie but all in vain. I've already posted my php code in my last post. "COOKIE PROBLEM". I think there is nothing wrong with code. may be i need to enable to load some library or something in xampp. Is there anyone who knows what setting do i need to do for enable cookies and in which file? Please help Can you send a cookie through ajax? Will it still be read by the browser? Hi again all, I wondered if anyone could help again (sorry). I have one single page which I would like to record a cookie when the user hits submit. The next time the user visits the site, I want it to recall the cookie and put the value in the textbox on the page. I think I have it storing the cookie (not sure though), but I am having trouble getting it to recall in the text box. I wondered if someone could look at this code and see where I am going wrong or help with what I need to add. New to PHP so having trouble getting my head around things. Thanks in advance. Code: [Select] <? setcookie('user',$userName,(time()+60*60*24*30) ); ?> <style type="text/css"> <!-- body,td,th { color: #FFFFFF; } body { background-color: #000000; } .style1 {font-family: Verdana, Arial, Helvetica, sans-serif} --> </style><form id="form1" name="form1" method="post" action=""> <label> <div align="center" class="style1"><strong>My Timetable Search</strong><br /> <br /> Enter Network User ID:<br /> <input type="text" name="txtUserID" id="txtUserID" value=""/> </div> <p align="center"> <label> <input type="submit" name="cmdGo" id="cmdGo" value="Show Timetable" onclick="setcookie('user',$userName,(time()+60*60*24*30);"/> </label> <br /> </p> <hr /> </form> <div align="center"> <?php $userName = $_POST["txtUserID"]; $hostname = "xxxxx"; $dbuser = "xxxxx"; $dbpassword = "xxxxxx"; $dbname = "xxxxx"; $LessonCount = 0; $db_link=mysql_connect($hostname, $dbuser, $dbpassword) or die("Unable to connect to the server!"); mysql_select_db($dbname) or die("Unable to connect to the database"); $fields_array=array(); $num_fields=0; $num_row=0; $sql= "SELECT core.UserID, wstt.Period, wstt.Lesson, wstt.Staff, wstt.Room FROM wstt INNER JOIN core ON wstt.Adno = core.Adno WHERE core.UserID='$userName'"; // find position of "FROM" in query $fpos=strpos($sql, 'from'); // get string starting from the first word after "FROM" $strfrom=substr($sql, $fpos+5, 50); // Find position of the first space after the first word in the string $Opos=strpos($strfrom,' '); //Get table name.

How can I use a cookie to pull data from my db. Right now I have it set up to pull data from a session variable, but I need it to be able to display data from both since I am implementing a remember me checkbox on my login. Current Code: $q = mysql_query("SELECT `firstname`, `lastname`, `firstname`, `lastname`, `email`, `entrepreneur`, `investor`, `companyname`, `companywebsite`, `founder`, `phone`, `address`, `city`, `state`, `zipcode`, `country`, `development`, `capitalamount`, `companydo`, `founderbuilt`, `understand`, `competition`, `money`, `demo`, `incorporation`, `companynameinv`, `phoneinv`, `addressinv`, `cityinv`, `stateinv`, `zipcodeinv`, `countryinv`, `angel`, `vc`, `capital` FROM `users` WHERE username= '" . $_SESSION['username'] . "'"); $r = mysql_fetch_assoc($q); if (!isset ($_GET['u'])&&($_SESSION['username'])||($_COOKIE['username'])) { echo "blahblah" Hello All I wrote a tiny piece of cookie code (to set and record cookies and hits) that works pretty well but seems to have a bug in it that I cannot figure out. First, here is the code: Code: [Select] <?php $my_cookie = (isset($_COOKIE['my_cookie'])) ? true : false; $countFile = "./data/count.txt"; $cookieFile = "./data/cookie.txt"; $dateTime = date('Y-m-d\,H:i:s\,U\,T\,O\G\M\T'); $remoteIPAddress .= $_SERVER['REMOTE_ADDR']; $remoteUserAgent .= $_SERVER['HTTP_USER_AGENT']; $cookieVal = $dateTime; $cookieVal .= ","; $cookieVal .= $remoteIPAddress; $cookieVal .= ","; $cookieVal .= $remoteUserAgent; $cookieVal .= "\r\n"; if(!$my_cookie){ // read the visit counter $countHandle = fopen($countFile, 'r'); $visitCount = intval(trim(@fread($countHandle, filesize($countFile)))); fclose($countHandle); // incremenet the visit counter $visitCount++; // write the new visit count and cookie value to their respective files $countHandle = fopen($countFile, 'w'); $cookieHandle = fopen($cookieFile, "a+b"); if(!preg_match('/bot/',$remoteUserAgent)){ fwrite($countHandle, $visitCount); fwrite($cookieHandle, $cookieVal); } fclose($countHandle); fclose($cookieHandle); setcookie("my_cookie", $cookieVal, time()+31556926); } else{ // read the visit counter $countHandle = fopen($countFile, 'r'); $visitCount = fread($countHandle, filesize($countFile)); fclose($countHandle); } ?> What is happening is that sometimes, not every time, but, sometimes my cookie.txt count gets a 0 (zero) written back to it and I can't figure out why. Can anybody see anything in there that would have this effect? Like I said, it only gets zeroed out from time to time. Thanks to all for taking the time to read. |
