PHP - Settings Cookies But Needs Page Refresh To Adapt Changes
Hello
I'm trying to build a plugin to get my site up to scratch for the new EU laws on cookies coming in place on the 26th What my main goal is a notification that when the users click accept the cookies set on machine but untill a "approval" cookie is found the site shouldn't set any cookies. Ive written this code, which allows me to set & unset a cookies via a form, using php and html, then depending on the submission either set or unset (which is a good start because im a noob!) but: the page needs an extra refresh in order to show the set cookie? does anyone know why or how i can resolve this? kind regards, and thank you Code: [Select] <? $set = $_POST["set"]; if($set == "on") setcookie(EURegulations, $set, time() + (20*365*24*60*60), www.domain.net); else if($set == "off") setcookie("EURegulations", "", time()-3600); ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>EU Cookie Plugin</title> </head> <body> <?php if (isset($_COOKIE["EURegulations"])) echo "Cookie Permission " . $_COOKIE["EURegulations"] . "!<br />"; else if(!isset($_COOKIE["EURegulations"])) echo "Cookie Permission off"; else echo "Error no cookie Set"; ?> <form name="setform" method="post" action="<?php echo $_SERVER['$PHP_SELF'];?>"> <button name="set" type="submit" value="on">On</button> <button name="set" type="submit" value="off">Off</button> </form> </body> </html> Similar TutorialsI am writing the code for my options page in my wordpress theme. It was working for awhile and the next time i checked, it couldnt save. When i hit save, it redirects to options.php. When i remove the code for the social options it still doesnt work and yet it was working before i included that code. What could be the problem here is the code

Hello, It's as subject says. Here is the code: <? //Config include_once "../../config/config.php"; //Variables $username = $_POST["username"]; $username = mysql_real_escape_string($username); $password = $_POST["password"]; $password = md5($password); //Check for User $query = "SELECT * FROM users WHERE username='$username' AND password='$password'"; $query = mysql_query($query); //If user not found if(mysql_num_rows($query)!="1") { echo "No User Found"; } //If User Found else { while($row=mysql_fetch_array($query)) { $fname = $row["fname"]; $lname = $row["lname"]; $userid = $row["id"]; $admin = $row["admin"]; } setcookie("fname", "$fname"); setcookie("lname", "$lname"); setcookie("userid", "$userid"); setcookie("admin", "$admin"); header('Location: ../../../portal/index.php'); } ?> On the page it forwards to, I write print_r($_COOKIE); Yet it doesn't show my newly set cookies, yet the above snipped does on the script code above. George Hello, I am having issues with getting cookies to function how i'd like them to. My goal is to be able to capture a cookie value from the url if a user comes to my site via something like adwords. An example URL they could come to is http://www.mysite.com?kw=hello I am trying to capture the word 'hello' and tie it to that visitor regardless of where they go on the site. I need to use that value to pass through if they complete a form on my site so that i can track the keyword source. I have included the following as the first line of code on every page of my site: Code: [Select] $kw = $_GET["kw"]; setcookie('kw',$kw); Then, if i go to this url: http://www.mysite.com?kw=hello and then later go to a url like this: http://www.mysite.com/page1.html, i am able to echo out the cookie on page1.html using the following code which is contained in page1.html: Code: [Select] echo $_COOKIE["kw"]; The problem is, if i then refresh page1.html i can no longer echo out the cookie--it disappears. I need the cookie to stay with the user no matter what page they are on within the site and not matter how many different pages they visit. I hope i am explaining myself in a way someone can understand. Perhaps cookies aren't the best way? Should i use sessions instead? Thanks in advance for your help i have already echoed title and included that file in my php script, a header file.... but now i want to refresh my php script if the comment has been successfully added else remain in the same page....it remains in the same page now with just a msg that the comment is added....but i cant see the comment unless i refresh the page... i get he headers already sent error when i put a header() there as i have included another php file which already echoes title to screen....so what do i do now? i want the comment to be displayed to the user once he clicks on save and not make it tedious for him to refresh....any suggestions?any way around? After I submit form data how can I force the page to refresh so I can see the changes take effect? I know this is probably a very basic question. I'm having trouble getting my script to refresh the page. If the username, password match it falls into this if statement. Sometimes it works and other times and won't refresh the page automatically. I'm trying to use this line to refresh the page Code: [Select] echo "<meta http-equiv='refresh' content='=2;index.php' />"; Here is the if statement Code: [Select] if(mysql_num_rows($checklogin) == 1) { // store the row returned from query $row = mysql_fetch_array($checklogin); // get email address from row returned $email = $row['EmailAddress']; // store user variables in session array $_SESSION['Username'] = $username; $_SESSION['EmailAddress'] = $email; $_SESSION['LoggedIn'] = 1; // boolean echo "<h1>Success</h1>"; echo "<p>We are now redirecting you to the member area.</p>"; echo "<meta http-equiv='refresh' content='=2;index.php' />"; } here is the entire index.php file Code: [Select] <?php include "base.php";?> <!-- base.php contains session_start() --> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>User Management System (Tom Cameron for NetTuts)</title> <link rel="stylesheet" href="style.css" type="text/css" /> </head> <body> <div id="main"> <?php // check if user is already logged in if(!empty($_SESSION['LoggedIn']) && !empty($_SESSION['Username'])) { ?> <h1>Pitch Shark Member Area</h1> <p>Thanks for logging in!

Hi everyone, Im using the code below to insert an item to auction, then calculate and display the time remaining until the auction ends.

I have a script where I use the code include("pagerefresh.php"); where pagerefresh.php is <?php $page = $_SERVER['PHP_SELF']; $sec = "0"; header("Refresh: $sec; url=$page"); ?> I use the include function several times on the page and everything's cool with it. But once I put this: <html> <head> <title>Title</title> <script type="text/javascript"> <?php some mysql function include("timecounter.js"); ?> </script> </head> in the page, the following error pops out whenever I use some of the form functions in the page.

And Merry Christmas!!!!! Thauwa Hi All, I was wondering if there is any way that a PHP page can update itself when a row in a DB is added or updated? I am trying to get a feed up and running and want it to update when a row is updated/inserted. Thanks Matt anyone know how to get rid of an echo when you hit refresh on the browser? My browser is remembering the echo from with in a if statement when refresh is hit even if the if statement remains false on refresh. Is it possible to refresh parent page before header() So let say i have 2 page, and 1st page is parent page and the other is pop up window Assume that there is an execution of certain script at the pop up window and it redirected to another page and redirected back again to that page As certain data being displayed in both pop up window and parent page..so i wish to have parent page being refreshed once pop up window execute header() is that possible?? I have an issue with refreshing pages on the website. I have a simple code using php to login to the website fill in a form and exit. The code works fine and adds the enterd data correctly in the table in MySql. I have another link where the user can retrieve the recods to update any fields after logging in. The problem I encountered was that the retreving records page does not show the newly added records until the page is refreshed on the server. Whenever the new record does not show, I just open the php code page save without making any changes to the code (just to enforce new time stamp), upload the page to the server only when I do that the new record shows. I would appreciate any help to solve this problem and not having to upload the page to get it to work. Thanks, MB I would like the page orderform.php to reload or refresh to normal after I click this link: this is what i have and this link is on a different page though... if($myError==true) echo "<br /><br />Click here to <a href='orderform.php?nocache='.time().'>go back...</a>"; else header("location: orderform.php"); Hi, I have a form with a submit button (Delete button). after I click the button I do few changes in database. Problem is that in this form, after the submit made, it still shows me old data that deleted.... So, I guess I need somehow to make a page refresh through a GET method. How do I do this? Thank u! Hello, I'm having trouble figured out how to do this... Basically I want update.php to run after the user hits the 'update' button, and after update.php runs (which will take about 60 seconds) I want the index.php to reload. How can this be done? thanks! <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Server List</title> </head> <body> <?php $mlink = @mysql_connect("localhost","user","pass"); mysql_select_db("dbname", $mlink); $result = mysql_query("SELECT * FROM ServerList"); while($row = mysql_fetch_array($result)){ echo $row['HostName'].

Code: [Select] <?php echo "<div class='gallery_row_divide'>"; include "processes/connection.php"; $table = "gallery"; $i = 0; $data = mysql_query("SELECT id, name, filetype FROM $table ORDER BY id DESC") or die(mysql_error); while ($datarow = mysql_fetch_array($data)) { $name = $datarow['name']; $id = $datarow['id']; //determine photo & thumbnail name and location if($datarow['filetype'] == "image/png") $type = "png"; else $type = "jpg"; $photo_name = "000". $id; $photo_name = substr($photo_name, -4); $photo_name = $photo_name. "." .$type; $thumbname = "tb_" .$photo_name; $thumbname_address = "uploads/thumbs/" .$thumbname; $photo_address = "uploads/" .$photo_name; //display image echo "<div class='gallery_photo_divide'><div class='gallery_photo_valouter'><div class='gallery_photo_valmid'><div class='gallery_photo_valinner'><a href='$photo_address' class='lightbox'><img src='$thumbname_address' alt='photo by $name' class='shadow pic' /></a><br />"; if(!empty($name)) echo "<div class='gallery_text_divide'>Photo taken by " .$name. "</div><!--end of .gallery_text_divide-->"; else echo "<div class='gallery_text_divide'> </div><!--end of .gallery_text_divide-->"; echo "</div><!--end .gallery_photo_valinner--></div><!--end .gallery_photo_valmid--></div><!--end .gallery_photo_valouter--></div><!--end of .gallery_photo_divide-->"; ++$i; if($i % 3 == 0) echo "</div><!--end of .gallery_row_divide--><div class='gallery_row_divide'>"; } if(!($i % 3 == 0)) echo "</div><!--end of .gallery_row_divide-->"; mysql_close($con); ?> Is there some way of a php include which is visible on every page (footer), itself having two php includes, but only one of which would be visible, then on the user refreshing the page or on visiting another page on the site, that include would be replaced with another php include? Preferably done without any js. Any help appreciated. Chris Hi All, Is there any way that PHP can detect if a page has been refreshed? Basically I have a form that when submitted, inserts a row in to a database, but I am finding that when I refresh the page, it repeats the insert statement. Any ideas? Thanks Matt When someone types in thier information in my Sign Up form i want the information they entered to stay after the page refresh. For example: I type in my information, but in the email field i forget the '@' symbol and then hit "Sign Up". Then the page would refresh and i would get an error message saying "You must enter a valid email address!" and all the information i typed in before would be gone and i'd have to start over with everything.. My question is, how can i make so that all the information I entered stays after the page refresh? Is there a simple way to do it or do I have to rewrite all my code? (i've provided it below) I know that you can use jQuery, AJAX and JS to acomplish this and also show the error message without refreshing the page but I don't know much about that and i'm trying to use as little JS as I can. So if there is another easier way? Here is my PHP script that holds the validation process and shows the errors etc: <?php class Register { private $username; private $first_name; private $last_name; private $password; private $passmd5; private $email; private $confemail; private $gender; private $birth_month; private $birth_day; private $birth_year; private $iagree; private $errors; private $token; public function __construct() { $this->errors = array(); $this->username = $this->filter($_POST['username']); $this->first_name = $this->filter($_POST['first_name']); $this->last_name = $this->filter($_POST['last_name']); $this->password = $this->filter($_POST['password']); $this->email = $this->filter($_POST['email']); $this->confemail = $this->filter($_POST['confemail']); $this->gender = $this->filter($_POST['gender']); $this->birth_month = $this->filter($_POST['birth_month']); $this->birth_day = $this->filter($_POST['birth_day']); $this->birth_year = $this->filter($_POST['birth_year']); $this->iagree = $this->filter($_POST['iagree']); $this->token = $_POST['token']; $this->passmd5 = md5($this->password); } public function process() { if($this->valid_token() && $this->valid_data()) $this->register(); return count($this->errors)? 0 : 1; } public function filter($var) { return preg_replace('/[^a-zA-Z0-9@.]/','',$var); } public function register() { mysql_connect("localhost","root","") or die(mysql_error()); mysql_select_db("membership") or die (mysql_error()); $sql = "INSERT INTO users(username,password,first_name,last_name,email,gender,birth_month,birth_day,birth_year) VALUES ('{$this->username}','{$this->passmd5}','{$this->first_name}','{$this->last_name}','{$this->email}','{$this->gender}','{$this->birth_month}','{$this->birth_day}','{$this->birth_year}')"; mysql_query($sql) or die(mysql_error()); if(mysql_affected_rows()< 1) $this->errors[] = "Could Not Process Form"; } public function user_exists() { mysql_connect("localhost","root","") or die(mysql_error()); mysql_select_db("membership") or die (mysql_error()); $data = mysql_query("SELECT username FROM users WHERE username = '{$this->username}'"); return mysql_num_rows($data) > 0 ? 1 : 0; } public function show_errors() { foreach($this->errors as $key=>$value) echo "<div class=errormessages> $value </div> <br />"; } public function valid_data() { if ($this->user_exists()){

(empty($this->birth_month)){ $this->errors[] = 'Select which month you were born!'; } if (empty($this->birth_day)){ $this->errors[] = 'Select which day you were born!'; } if
