This is a PHP script I use to get the referring website for each new visitor to my site.
If the visitor came from Google, I get the keyword they used to find the site.
This data is stored in the session then included along with the data from the contact form when an enquiry is sent. This allows clients with little knowledge of analytics to track converting keywords.
I need to convert this PHP to work on a site that uses .aspx pages. After researching asp.net for several hours, I feel like I still don't have a clue where to start!
<code>
<?php
session_start(); // start up your PHP session!
if (empty($_SESSION['google'])) {
// if session is empty, take the referer
$thereferer = strtolower($_SERVER['HTTP_REFERER']);
// see if it comes from google
if (strpos($thereferer,"google")) {
// delete all before q=
$a = substr($thereferer, strpos($thereferer,"q="));
// delete q=
$a = substr($a,2);
// delete all FROM the next & onwards
if (strpos($a,"&")) {
$a = substr($a, 0,strpos($a,"&"));
}
// we have the key phrase
$_SESSION['google'] = urldecode($a);
$_SESSION['referer'] = 'Google';
}
}
if (empty($_SESSION['referer'])) {
$_SESSION['referer'] = $_SERVER['HTTP_REFERER'];
}
?>
</code>
I'd really appreciate a point in the right direction with this.
Thanks.
You need to read up on the HttpRequest and HttpResponse classes. More specifically, the Request.ServerVariables collection, the Request.Cookies object, and the Response.Cookies object.

I am currently trying to build a cURL to automatically log in to a test account at a certain website I am building. So far, so good - it logs me in and displays the first account page after the login sequence.
What I would like to do, is the following:
Retrieve the html code of that page, find a certain part of it and set it as a session variable.
The part in question is:
<span class="welcome-user"><span>Welcome, Lakumba Lekendi</span>Sign Out</span>
Any pointers on how I can achieve that? "Lakumba Lekendi" will not be a constant, since it will change for every user that logs in to their account. I literally wanna find the starting span tag ( class="welcome-user" ) and isolate all of its contents till the closing span tag.
I suppose I can just grab the file contents via file_get_contents, but how do I find that specific piece of code in there, and isolate it properly to set it as a session variable?
If you don't want to learn all those dedicated methods, you can always do exploding until you get it:
$h = '<span class="welcome-user"><span>Welcome, Lakumba Lekendi</span>Sign Out</span>';
$a = explode('<span class="welcome-user"><span>',$h);
$a = $a[1];
$a = explode('</span><a href="/signout',$a);
$a = $a[0];
echo $a;
Gives:
Welcome, Lakumba Lekendi
I am developing a simple system of sample products with Object Oriented PHP, very simple thing. So far, no problem, but I have to create a button that adds a product code recorded in the database to a form in the sidebar. I do not know to develop a shopping cart with OO PHP, and codes that I find always give error because of the call of the database, or when the data list. I've been thinking of doing for JS, any help?
sorry my bad english
I got it, first I did when I click a link step by GET and the ID Code I need after seto it in a cookie, each cookie with an ID. Then I check if cookie has registered with the IDs. Not the best and most correct, but it works (more or less). Now another problem, I need to click two times to get the result as it passes by id and need to be caught refresh = /
I think it was a bit confusing but it is the maximum that dyslexia allows me to do hehehe
Here I set up the structure with the data I have in my product page:
add
<?php
$cod_get = $_GET['cod'];
setcookie("SITENAME_cod_".$id_get."", $cod_get, time()+3600, "/","", 0);
?>
And here I have a loop checking if cookie with ids, I think it will give problems, but for now I think it works ...
Thank you all.
$produto = new produtos();
$i = 0;
$produto->selecionaTudo($produto);
$produto->selecionaCampos($produto);
while($res = $produto->retornaDados()):
$res->id;
$i++;
$get_cookie = $_COOKIE['SITENAME_cod_'.$res->id.''];
if (isset($get_cookie)) {
echo $get_cookie.', ';
}else{
echo "";
}
endwhile;
I have a custom report called my-newsletters in Google analytics. I want to fetch this report with a php call to $ga->requestReportData(...) and then parse the response and format it up.
First I made an account to collect all my newsletter open and click hits - each time someone opens a newsletter or clicks on a link in the newsletter I capture that with a call to the __utm.gif on Google. That part is working and I include in the call ( in the Landing Page aka utmp parameter) some data such as the word 'open' and 'click' to distinguish the events and also some other data i hope to parse out later, plus i use the campaign field and maybe I should do something with the source field too - now I just dup the utmp field. So far that part seems to work.
Now I need help to define a report that will return that utmp and campaign field info and the number of hits each has taken, sorted by date of hit I guess. then i need to call that report from my php and then later parse it - the parsing part I'm not worried about yet.
PS: here is the code I use to generate the utm url
function getGoogleUtmUrl($source='Emails', $referer='opens', $estid='0',$mailid='0', $campaign){
$stat_id='MO-xxx31982-1';
$var_utmcs=urlencode( 'UTF-8');
$var_utmac = $stat_id;
$var_utmhn = 'mysite.com'; //enter your domain
$var_utmn = rand(1000000000,9999999999); //random request number
$var_cookie = rand(10000000,99999999); //random cookie number
$var_random = rand(1000000000,2147483647); //number under 2147483647
$var_today = time(); //today
$var_referer = $referer; //referer url
$utm_source = 'my_newsletter';
$utm_medium = 'Emails';
$utm_campaign = $campaign;//$_GET['url'];
$var_uservar = $estid.'_'.$mailid; //enter your own user defined variable
$var_utmp = 'mysite.com/newsletters/'.$referer.'/'.$estid.'/'.$mailid;//.$estid;//$_GET['url']; //this example adds a fake file request to the (fake) tracker directory (the image/pdf filename).
$urchinUrl1 = 'http://www.google-analytics.com/__utm.gif?utmwv=4.3&utmn='.$var_utmn.'&utmsr='.$referer.'&utmcs='.$var_utmcs.
'&utmul=en&utmje=0&utmfl=-&utmdt='.$utm_campaign.'&utmhn='.$var_utmhn.
'&utm_source='.$var_utmp.'&utm_medium='.$utm_medium.'&utm_campaign='.$utm_campaign.'&utmr='.$var_referer.
'&utmp='.$var_utmp.'&utmac='.$var_utmac.
'&utmcc=__utma%3D'.$var_cookie.'.'.$var_random.'.'.
$var_today.'.'.$var_today.'.'.$var_today.
'.2%3B%2B__utmb%3D'.$var_cookie.'%3B%2B__utmc%3D'.
$var_cookie.'%3B%2B__utmz%3D'.$var_cookie.'.'.$var_today.
'.2.2.utmccn%3D(direct)%7Cutmcsr%3D(direct)%7Cutmcmd%3D(none)%3B%2B__utmv%3D'.
$var_cookie.'.'.'%3B';
// Now fire off the HTTP request
echo "urchinURL1 == ".$urchinUrl1.' '.__FILE__.' '.__LINE__.'<br/>';
return $urchinUrl1;
seems like over kill to me but it works, I tried the code at https://developers.google.com/analytics/devguides/collection/other/mobileWebsites and it doesn't work - the opens and clicks do not register in analytics - at least not on the real time page.
Please help.
I suggest that you build your report query first, I recommend that you use Google Analytics Query Explorer for that.
And next use the reporting API from PHP to transpose the resulting query and extract the data from within your app.
Here is what I would do in JavaScript. Is there any way to do it in php?
I am working on a project that needs this functionality but cannot use JavaScript.
setInterval ( "checkHistory()", 1000 );
function checkHistory() {
if (oldHistLength != history.length) {
removegateway();
oldHistLength = history.length;
}
}
Sorry to say that it's not possible to do that using PHP. Your only option is to use JavaScript somewhere.
You can however achieve what I believe you're trying to do with another technique - PHP Sessions and Request URIs.
This involves storing the user's accessed URLs into a variable (or you could use MySQL) which can be referenced anywhere on the website within that current session.
Here's an (untested) example:
<?php
session_start();
// Retrieve/create the current list
if( isset($_SESSION['history']) ) {
$history = $_SESSION['history'];
} else {
$history = new array();
}
// Add the current URL to the history array
array_push($history, $_SERVER['REQUEST_URI']);
// Do anything else you want to here
// Store the array again
$_SESSION['history'] = $history;
?>
In your code, you can keep an array containing the values of $_SERVER['php_self'], serialize() it, and store it in a session variable. This may not be sufficient for what you are trying to do though. I'm not sure what removegateway() does, but is this code attempting to prevent the back button from being used?
If you prevent the pages from being cached, you might be able to compare the second to the last value in your array to the current page, and if they match, you detected a back button. This would only be possible if there's no way to go back to the previous page on the front end.
Preventing the back button is generally considered a Bad Thing, so it might be better to reconsider the way you are doing things and come up with a better solution.
I'm looking for a good, simple PHP function to get my latest Facebook status updates. Anyone know of one?
Thanks!
EDIT: I've added a half-solution below.
Or if anyone knows a good way to read in the RSS feed and spit out the recent status update?
A quick check on PEAR found Services_Facebook
This is an incomplete answer, but this is what I've gotten so far:
First: add the developer application on FB. Then create a new application. Call it whatever you want.
Second: Download the PHP client. Dump it somewhere on your webhost, i.e. /facebook/
Third: Copy the following beginner code to get yourself started into a php file:
<?php
require_once('facebook/php/facebook.php');
$facebook = new Facebook("YOUR_API_KEY","YOUR_SECRET_KEY");
$result = $facebook->api_client->fql_query("SELECT status FROM user WHERE uid = YOURIDNUMBER");
// OR --- they both get the same data
$result = $facebook->api_client->users_getInfo(YOURIDNUMBER,'status');
print_r($result);
echo "<pre>Debug:" . print_r($facebook,true) . "</pre>"; // debug info
?>
Other info:
You must be logged in and have the
application added. OR you give the
application offline_access
permissions and have the
aapplication added.
You can add offline_access by typing
in the following url:
http://www.facebook.com/authorize.php?api_key=YOUR_API_KEY&v=1.0&ext_perm=offline_access
more info on permissions found here: http://wiki.developers.facebook.com/index.php/Extended_permissions
I'm at a stopping point: anything my
program calls the fql query or
users_getInfo, my page stops
executing the php? I'm guessing
there are a limited amount of calls
for new applications? I've never
done any FB development so I'm
completely new to it. Maybe make
the call and save your recent status
(or most recent statuses) in your
own DB to prevent excessive calls to
the API?
I hope this helps someone get started!
EDIT: It seems that FB won't let you access someones status, even if the offline_access is on, unless you are that person or their friend (depending on their privacy settings).
I did however, finally manage to find the RSS feed in the new profile version: http://www.new.facebook.com/minifeed.php?filter=11
I have found a way to fetch your latest facebook status. This is how you do it:
1) Create a facebook app, and copy your application secret and application id.
2) Grant the app read_stream and offline_access to your profile. (http://developers.facebook.com/docs/authentication/permissions) To fetch your latest status the app needs an access_token. With offline_access granted the access_token should "never" expire. The easiest way to do this is to click the button generated by this code: (be sure to fill in 'your app id' and set cookie to true!)
<fb:login-button perms="read_stream,offline_access"></fb:login-button>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>FB.init({appId: 'your app id', status: true, cookie: true, xfbml: true});</script>
3) Now try to find out what access_token it is using. The access_token is saved in the fbs_appId cookie. Locate it using your browser or using $_COOKIE['fbs_appId']. Look for access_token=....
4) Now that you have a (hopefully) never expiring access_token you can use the following code:
$access_token='xxxxxxxxxxxxxxxxxxxx';
$appId='123456789132456789';
$appSecret='xxxxxxxxxxxxxxxxxxxx';
$profileId='123456789';
//http://github.com/facebook/php-sdk/blob/master/src/facebook.php
require 'facebook.php';
$facebook = new Facebook(array('appId' => $appId,'secret' => $appSecret));
$response = $facebook->api('/'.$profileId.'/feed?limit=1&access_token='.$access_token);
5) The message part should be located: $response['data'][0]['message']
I don't know HOW long the access token is valid. Facebook says:
Enables your application to perform authorized requests on behalf of the user at any time. By default, most access tokens expire after a short time period to ensure applications only make requests on behalf of the user when the are actively using the application. This permission makes the access token returned by our OAuth endpoint long-lived.
Here is a REALLY simple function if you just want to get the latest status. It doesn't depend on the Facebook SDK or anything. You just need CURL and JSON support.
Simple PHP function to get facebook status
I never seem to get along with PEAR, but if you have better luck than I, then the PEAR solution seems the best route long term.
Another idea is to explore the Facebook Developer API library and see if that might give you anything you are looking for.
Lastly, there used to be a way to get an RSS feed... but I can't seem to find any instructions that work anymore, but you might poke around Facebook help if that interests you. Mine ends up looking something like this:
http://www.new.facebook.com/feeds/status.php?id=[idnumber]&viewer=[viewer]&key=[key]&format=rss20
I got it working using Jens' post to retrieve a valid access_token. Then, I extracted the status messages and the time of posting from the xml file using the following code (you can change $limit to display more or less status messages, or use a form to change it).
Be sure to put in your Facebook ID and the access token you got from the app you created (see Jens' post). You can check the output of this script here.
Have fun!
<?php
if(isset($_POST['limit'])) {
$limit = $_POST['limit'];
}
else {
$limit = 3; // number of status messages to display
}
$f = fopen ("https://api.facebook.com/method/status.get?uid=YOUR_FACEBOOK_ID&limit=".$limit."&access_token=YOUR_ACCESS_TOKEN", "r");
while ($line= htmlentities(fgets($f))) {
if ($line===FALSE) print ("FALSE\n");
else
{
$content = $content." ".$line;
}
}
fclose ($f);
$message = explode("<message>", $content); // search for the <message> tag
$message_cnt = count($message);
$msg_index = 0;
$time = explode("<time>", $content); // search for the <time> tag
for($i=1; $i<$message_cnt; $i++)
{
$tmp = explode("</message>", $message[$i]);
$msg[$msg_index] = $tmp[0]; // status message
$tmp2 = explode("</time>", $time[$i]);
$t[$msg_index++] = $tmp2[0]; // time of posting
}
for($i=0; $i<$msg_index; $i++)
{
echo("<span class=\"status\">".preg_replace('!\015\012|\015|\012!','<br>',$msg[$i])."</span><br>\n
<span class=\"date\">on ".date("d.m.Y", $t[$i])." at ".date("H:i",$t[$i])."</span><br><br>\n");
}
?>
I have tried loads of tutorials over the last few days and none of them have worked. I think it may be due to facebook changing their api requirements. This is the only one I found that works at the moment:
http://www.deanblog.co.uk/article/13/adding-a-facebook-status-feed-to-your-website-with-php
Just use PHPforFB framework (www.phpforfb.com/en/) for the fastest way.
The code looks like this:
require_once('phpforfb_framework.php');
$structInit = array('app_id' => APP_ID,'app_name' => APP_NAME,'sec_key' => APP_SECKEY);
$FacebookAPP = new PHPforFB($structInit);
if($FacebookAPP->lastErrorCode>0){
//Creation failed => Display error message and exit
echo "PHPforFB Error: ".$FacebookAPP->lastErrorCode." -> ".$FacebookAPP->lastError;
}else{
//PHPforFB framework established
if($FacebookAPP->userLoggedIn === TRUE){
//If the user is logged in at Facebook:
//Here you can determine if the user has at least once before
//granted basic permissions to your application.
if($FacebookAPP->userAuthenticated === FALSE){
//The user has not yet granted permissions
//**your code here**
}else{
//The user has already granted permissions, therefore his Facebook ID
//is known to us. It is always available in $FacebookAPP->userID:
$userID = $FacebookAPP->userID;
//**your code here**
}
}
}
Since I couldn't use the API route, I went with the RSS found at: http://www.new.facebook.com/minifeed.php?filter=11
And used the following PHP function, called StatusPress, with some of my own modifications, to parse the RSS feed for my Facebook status. Works great!
<?php
// see http://github.com/facebook/php-sdk/blob/master/facebook.php
require './facebook.php';
// Create our Application instance.
// see http://www.youtube.com/watch?v=jYqx-RtmkeU for how to get these numbers
$facebook = new Facebook(array('appId' => 'XXX','secret' => 'XXX'));
// This call will always work since we are fetching public data.
// this could be /username or /username/friends etc...
// see developer api for FQL for examples
$status = $facebook->api('/haanmc/feed?limit=1');
?>
<p><?php print $status['data'][0]['message']; ?></p>
<p>Likes: <?php print $status['data'][0]['likes']; ?> | Comments: <?php print count($status['data'][0]['comments']['data']); ?></p>
<textarea style="width: 95%; height: 600px;"><?php print_r($status); ?></textarea>
