I have a landing page, that sets a cookie whenever a user enters the page. If this cookie is set, it redirects the user to my homepage. The problem is that if my user wants to enter the landing page again and they already have this cookie set, it will automatically redirect them to the homepage. My domain will be set on the landing page, meaning that every time a user enters my site they will see this page.
Is there a way to dynamically allow access to the landing page with the cookie? My users should be able to enter the landing page at will; however I also want the users to be directed to my homepage if they are directly entering my website.
Here's my code:
PHP:
<?php
$time = time() + (60 * 60 * 24);
if (isset($_COOKIE['landing'])) {
header('Location: home.php');
} else {
setcookie("landing", true, $time);
}
?>
Well, you could use a query parameter, eg. index.php?noredirect=1, and in your script:
if(isset($_COOKIE['landing']) && $_GET['noredirect'] != 1) {
header('Location: home.php');
} else if(!isset($_COOKIE['landing'])) {
setcookie('landing', true, $time);
}
Now if you append ?noredirect=1 to the url, the user will not be redirected, but by default they will (if the cookie is set).
You need to know if the user wants to stay or not. So you will have to set a variable or something like this.
if ( isset( $_COOKIE['landing'] ) && !$user_wants_to_stay ) {
header( "Location: home.php" );
} else {
...
}
You could use the session or a second cookie which will be set via javascript or simply a get variable in the URL

if(isset($_COOKIE['language']) && isset($_COOKIE['page'])) {
header("Location: index.php?j=".$_COOKIE['language']."&str=".$_COOKIE['page']);}
if(isset($_COOKIE['language'])) {
setcookie('language', $_GET['j'], time()+3600); /* expire in 1 hour */
setcookie('page', $_GET['str'], time()+3600); /* expire in 1 hour */
}
When i'm trying to use header as a redirect from page. I got a message
redirected you too many times. Try clearing your cookies.
You only need to redirect if the j and str parameters are NOT specified.
So when the user visits: index.php redirect to index.php?j=value&str=value.
But if the users visits: index.php?j=value&str=value do not redirect at all.
This is easily accomplished by checking those two parameters are not set before redirecting:
if (isset($_COOKIE['language']) && isset($_COOKIE['page']) && !isset($_GET['j']) && !isset($_GET['str'])) {
header("Location: index.php?j=".$_COOKIE['language']."&str=".$_COOKIE['page']);
}
I created this Cookie alert bar for my site, it works as intented. But you need to click the close link twice to close down the warning for some reason that I cannot figure out.
I use this following function to check if cookie exists or not.
function checkIfCookieExist($cookieName) {
if(isset($_COOKIE[$cookieName])) {
return true;
}
else {
return false;
}
}
if cookie does not exist, and the cookie get parameter exists and equals 1 I create a cookie
if (!checkIfCookieExist('cookieConfirmation') && isset($_GET['cookie']) && $_GET['cookie'] == 1) {
$cookieName = 'cookieConfirmation';
$cookieValue = 'Cookie confirmation';
$cookieDuration = 86400 * 30 * 3;
setcookie($cookieName, $cookieValue, time() + $cookieDuration);
}
Prints out the cookie bar, links to index with a get parameter for the cookie
function renderCookieBar() {
echo('
<div id="cookieBar">
<p>blabla cookie, cookies on this site yo</p>
I understand, close this box!
</div>
');
}
Calls function to print out cookiebar at given place in my html code
if(!checkIfCookieExist('cookieConfirmation')) {
renderCookieBar();
}
I appreciate any answers or help,
Cheers!
When you set the cookie in the header, the cookie is not directly present; means: the cookie is available up on the next page hit.
Check the manual: http://php.net/set_cookie
Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE array. Cookie values may also exist in $_REQUEST.
You can either
1. Set the cookie and immediately reload the page
Set the cookie and force a browser refresah by using header("Refresh:0");.
if (!checkIfCookieExist('cookieConfirmation') && isset($_GET['cookie']) && $_GET['cookie'] == 1) {
$cookieName = 'cookieConfirmation';
$cookieValue = 'Cookie confirmation';
$cookieDuration = 86400 * 30 * 3;
setcookie($cookieName, $cookieValue, time() + $cookieDuration);
header("Refresh:0");
}
2. Use Javascript
When setting the cookie with JavaScript it is directly available from the browser. You may also rewrite your script, so the JavaScript sets the cookie and removes the notification bar.
There are many solutions (also here on SO) how to work with cookies in JavaScript easily. If you are using a JavaScript library like jQuery you also have plugins handling the cookies.
I have a site where the phone number in the header file needs to change depending on the referrer. If someone comes to the site via google, for example, the phone number is different that if they came directly to the site.
I have it working, except for when the user goes to a different page on the site. The code checks the referrer and changes the number to the direct number.
What I want is for the number to be set by the referrer the first time the user visits the site, and for it not to change. I imagine cookies or sessions are the way to go here, I"m just not sure how the code should be structured.
if (!empty($_SERVER['HTTP_REFERER'])) //user has come via search engine or a page within our site
{
$referer = $_SERVER['HTTP_REFERER'];
if (strpos($referer,'google') !== false) {
$callin_number='1-444-444-4444';
$callin_dialer=preg_replace("/[^0-9,.]/", "", $callin_number);
}
elseif (strpos($referer,'bing') !== false) {
$callin_number='1-111-111-1111';
$callin_dialer=preg_replace("/[^0-9,.]/", "", $callin_number);
}
else {
$callin_number='1-222-222-2222';
$callin_dialer=preg_replace("/[^0-9,.]/", "", $callin_number);
}
}
else { //user has come directly to site
$callin_number='1-333-333-3333';
$callin_dialer=preg_replace("/[^0-9,.]/", "", $callin_number);
}
If you want to use session or cookie:
semi-pseudo:
<?php
session_start();
if ( !isset( $_SESSION['referer'] ) )
{
put your code here, and put whatever you need to session:
$_SESSION['referer'] = ...
$_SESSION['dialin'] = ....
}
and use $_SESSION['referer etc'] in your code instead of $referer etc.
$_SESSION['referer etc'] will be available on the next page load,
the IF condition above will be false on the next page load.
Cookies are just a bit different: http://php.net/manual/en/function.setcookie.php
I'm having two issues with setting and retrieving cookies.
Cookie gets loaded but can't be called until page is refreshed. Meaning that the cookie shows up in developer tools but not when trying to use its value on the page. The value does seem available to use on page after refreshing.
Cookie is not available across entire domain and subdirectories. For example, if the user enters at http://example.com/sub/ the goes to http://example.com/, the cookie gets destroyed.
Here's my code:
$ad_source = $_GET['source'];
$date_of_expiry = time() + (86400 * 7);
setcookie('ad_source',$ad_source,$date_of_expiry,'/');
if ( $_COOKIE['ad_source'] == 'adwords_campaign_01' ) {
echo '... do something';
} elseif ( $_COOKIE['ad_source'] == 'adwords_campaign_02' ) {
echo '... do something else';
}
I'm trying to to show different information throughout entire site by determining what adwords campaign the user clicked in on.
I don't usually use cookies and prefer to set a session, but in this case I want be able to track the source for a longer amount of time.
Everything is working as expected now. A little more insightful information into cookies at this post helped a lot.
PHP cookie set in second refresh page
Redirect user to page after cookie is set. Second request from browser sends cookie, server returns info relative to its value.
Check to see if $ad_source is set before creating cookie.
The updated code:
$ad_source = $_GET['source'];
$date_of_expiry = time() + (86400 * 7);
if ( $ad_source ) {
setcookie('ad_source',$ad_source,$date_of_expiry,'/','example.com');
if ( $_COOKIE['ad_source'] == 'adwords_campaign_01' ) {
header( 'Location: http://example.com/' );
echo '... do something';
} elseif ( $_COOKIE['ad_source'] == 'adwords_campaign_02' ) {
header( 'Location: http://example.com/' );
echo '... do something else';
}
}
I have 3 pages that I am trying to "track" so to speak. The signup process is 3 pages. Basically, I'm not wanting to count hits that are out of sequence (ie. if the user checks back into the thank you page (3rd page)) I don't want it to count a conversion again.
So something like this
1. User enters landing page +1 hit
2. User enters intermediary page +1hit
3. User enters thank you page +1 conversion
I know how to increment the count pretty easy for hits, but am unsure how to "not" count it if they are out of sequence.
You would set up a session variable so that on page 1 it was set to '1', page 2 = '2' and so on, but only set the variable if it is currently less then the current page number, so:
session_start();
if($_SESSION['cur-page'] < [CURRENT PAGE NUMBER]) {
$_SESSION['cur-page'] = [CURRENT PAGE NUMBER];
logHit();
}
Where logHit() tracks the page hit.
SESSIONS will solve your problem here.
On the first page do something such as:
session_start();
$_SESSION['page'] = '1';
// Store signup values in session
On the second:
session_start();
if ($_SESSION['page'] != 1 || $_SESSION['page'] != 3) {
header("Location: /page1");
exit();
} elseif ($_SESSION['page'] == 'complete') {
header("Location: /resubmit-error");
} else {
$_SESSION['page'] = 2;
}
// Store additional values in session
On the third:
session_start();
if ($_SESSION['page'] != 2) {
header("Location: /page2");
exit();
} elseif ($_SESSION['page'] == 'complete') {
header("Location: /resubmit-error");
} else {
$_SESSION['page'] = 3;
}
// Store additional values in session again and submit values to database or other source.
And finally the thank you page:
if ($_SESSION['page'] != 3) {
header("Location: /page3");
} elseif ($_SESSION['page'] == 'complete') {
header("Location: /resubmit-error");
} else {
$_SESSION['page'] = 'complete';
// Store data
}
On final submission of the third page redirect to completion / thank you page.
With this method a user wouldn't simply be able to return to the final page without re-completing the form.
Set a cookie or session variable called step. Before you run the tracking code, make sure the current step is greater than the step stored in the cookie, else don't track it. Usually for conversion tracking, it's desirable to use cookies over a session because you can track conversions for 30 days (or however long you want), rather than a short session which usually ends when a user closes the browser window.
On Page 1
$step=1;
if (!$_COOKIE['step']) {
setcookie('step',$step,time()+(86400*30),'/','.yourdomain.com');
//run tracking code (log database, whatever)
}
On Page 2+
$step=2;
if ($_COOKIE['step'] && $_COOKIE['step']<$step) {
setcookie('step',$step,time()+(86400*30),'/','.yourdomain.com');
//run tracking code (log database, whatever)
}
