My bag of tricks

Utiliser Google Analytics Export Api

Quentin — Tue, 04 Oct 2011 17:11:44 +0000

Dans cet article je vous propose une solution pour récupérer le nombre de visiteurs d’un de vos site tracé par google analytics. Cela deux étapes :

Authentification : utilisant la méthode ClientLogin avec votre email et mot de passe de votre compte google pour récupérer un auth token
Requête : utilisant le auth token.

Authentification

$url = 'https://www.google.com/accounts/ClientLogin';
$fields = array(
 'accountType'=>urlencode('GOOGLE'),
 'Email'=>urlencode('YOUR EMAIL'),
 'Passwd'=>urlencode('YOUR PASSWORD'),
 'service'=>urlencode("analytics"),
 'source'=>urlencode('GROUP NAME-APP NAME-VERSION')
 );

$fields_string='';
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');

$ch = curl_init();
// utile pour les problème de ssl (mais pas parfait niveau sécurité)
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

if(($result = curl_exec($ch))===false)
{
 curl_close($ch);
 exit('Curl Error: '.curl_error($ch));
}
curl_close($ch);

echo $result;
/*
de la form "**********************\n Auth=********"
*/

Il faut récupérer la variable Auth Si vous ne savez pas comment :


if(strpos($result,"\n")!==false)
{
  $results=array();
  $result=explode("\n",$result);
  foreach($result as $r)
  {
    if(strpos($r,'=')===false)
    {
      continue;
    }
    $temp = explode('=',$r,2);
    $results[$temp[0]] = $temp[1];

  }

}
$auth = $results['Auth'];

Requête

ensuite on peut faire les requêtes qu’on veut. Un exemple simple : le nombre de visiteurs depuis le début du mois:

</pre>
$url = 'https://www.google.com/analytics/feeds/data?'.
'ids=SITE ID exemple : ga:12345&metrics=ga:visits&start-date='.$first_day_of_last_month.'&end-date='.$last_day_of_last_month.'&v=2';

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_HTTPHEADER,
array( "GData-Version: 2",
'Authorization: GoogleLogin auth='.$_SESSION['ga']['auth']
));
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
if(($result = curl_exec($ch))===false)
{
curl_close($ch);
exit('Curl Error: '.curl_error($ch));
}
curl_close($ch);

echo $result; // xml

On peut traiter facilement le résultat, par exemple dans notre cas :

$doc = new DOMDocument();

$doc->loadXML(request($params));

$metrics = $doc->getElementsByTagName('metric')->item(0)->getAttribute('value');

echo 'Visiteurs : '.$metrics;

[Javascript] quelques astuce de compatibilité

Accéder à la fenêtre parent avec Opéra

Un petit truc à ce rappeler sur Opéra : lorsqu’un script ce trouve dans une iframe veut appeler une fonction qui se situe dans la fenêtre parent : parent.foo(); la fonction foo() doit obligatoirement se trouver dans le <head> sinon l’appel echoue.

iframe Cross Domain et cookie de session

Si vos utilisateur sont logué sur un site hébergé sur un serveur A, lorsqu’une page d’un serveur B insert une iframe du site A, l’iframe n’a pas accés au cookie de session, l’utilisateur n’est donc pas logué, et parfois même cela réinitialise la session sur le serveur A. Une technique simple consiste a passé par une page intermédiaire i.php.

fenetreSurB.php


<body>
<iframe src="http://A/i.php?page=pageSurA.php"></iframe>
</body>

i.php


<body>
<div id="content">
</div>
<script type="text/javascript">
$.post("http://A/<?php echo $_GET['page'];  ?>",
function(d)
{
$('#content').html(d);
});
</script>
</body>

voilà , ainsi l’utilisateur apparaît comme connecté dans l’iframe.

plugin jQuery backgroundPosition + hack Opéra

Le plugin http://plugins.jquery.com/project/backgroundPosition-Effect permet d’animer correctement backgroundPosition dans jQuery. Mais dans Opéra qui ne connait pas background-position-x et background-position-y, l’animation d’un des deux composantes reste impossible d’où une version modifier du plugin que l’on utilise de la façon suivante :


$('.element').animate({backgroundPosition: 'initial 40px'},'fast');
// anime baground-position-y jusqu'a 40px

$('.element').animate({backgroundPosition: '40px initial'},'fast');
// anime baground-position-x jusqu'a 40px

Install the Symfony framework on Windows

Quentin — Tue, 12 Apr 2011 07:16:59 +0000

Symfony est un framework php de développement de site web.Comme d’autres, notamment cakePHP, il permet de facilité le développement de site web, et offre des outils puissants (Debug, …)

Je m’intéresse a ce framework car il est open source, très suivie, et qu’il est très puissants (le site du zero et dailymotion l’utilisent) .

Il y a un chose qui est assez nouvelle (surtout pour les utilisateur de windows) c’est l’utilisation de ligne de commande pour effectuer des tache, qu’on a donc plus a faire a la main . Le problème pour ceux qui on pas l’habitude de l’utilisé, c’est qu’il faut faire en sorte qu’elle marche, et qu’elle sorte la même chose que sur les tutoriels, et pas “symfony n’est pas reconnue en tant que commande int…”, voici donc comment s’y prendre.

Tout d’abord il faut avoir un serveur local installé.

-Télécharger le dernière version stable de Symfony.

-Repéré ou ce trouve le fichier php.exe.
Pour cela faite une recherche dans le dossier d’installation de votre serveur local

-Dézipez symfony dans le même dossier que php.exe

[cakephp] upload images component

Quentin — Sun, 12 Dec 2010 11:59:09 +0000

Voici un petit composant que j’ai créé afin d’uploader des images facilements dans cakePhp. Il permet en quelques ligne de décider quelles tailles d’ images on veut et dans quels dossier en lui donnant en paramètre des options très simple comme :

$option = array(0 => array('folder'=>'',
 'width'=> 1600,
 'height'=> 1600),
 1 => array('folder'=>'thumb',
 'size'=> '210x310',
 'crop' => true));

voici le code source du composant. Il a été inspiré d’un petit composant d’upload d’image simple.


<?php
/*
 File: /app/controllers/components/QBimage.php
*/
class ImageComponent extends Object
{
 /*
 *    Uploads an images with options : images with max size, cropped images with max height and width.
 *   each image can be put on different folder
 *     Directions:
 *    In view where you upload the image, make sure your form creation is similar to the following
 *    <?= $form->create('FurnitureSet',array('type' => 'file')); ?>
 *
 *    In view where you upload the image, make sure that you have a file input similar to the following
 *    <?= $form->file('Image/name1'); ?>
 *
 *    In the controller, add the component to your components array
 *    var $components = array("QBImage");
 *
 *    In your controller action (the parameters are expained below)
 *    $op = array(0=>array('size'=>1600),
 *               1 => array('folder'=>'thumb', 'crop'=>true, 'size'=>'250x400'));
 *    $filename = $this->Image->upload_images($this->data,"name1","sets",$op);
 *    this returns the file name of the result image.  You can  store this file name in the database
 *
 *    Note that your image will be stored under the $folderName
 *    Image: /webroot/img/$folderName/*
 *
 *    Finally in the view where you want to see the images
 *    <?= $html->image('sets/big/'.$furnitureSet['FurnitureSet']['image_path']);
 *     where "sets" is the folder name we saved our pictures in, and $furnitureSet['FurnitureSet']['image_path'] is the file name we stored in the database

 *    Parameters:
 *    $data: CakePHP data array from the form
 *    $datakey: key in the $data array. If you used <?= $form->file('Image/name1'); ?> in your view, then $datakey = name1
 *    $folderName: the name of the root folder
 *    $options: an array with the upload options
 *               $option = array(0 => array('folder'=>'',
 *                                           'width'=> 1600,
 *                                           'height'=> 1600),
 *                               1 => array('folder'=>'thumb',
 *                                           'size'=> '210x310',
 *                                           'crop' => true));

Redirection of the Whole Url with UrlReWriting

Quentin — Fri, 15 Oct 2010 00:01:25 +0000

Voici une astuce pour redirigé tout un domaine vers un autre en utilisant le module UrlReWriting dans un fichier .htaccess.

exemple : on veut rediriger tout ce qui pointe sur www.monsite.fr vers monsite.fr

Une simple page de redirection ne suffirait pas a rediriger un lien comme
www.monsite.fr/news/sports?until=20-10-2009
vers : monsite.fr/news/sports?until=20-10-2009

il faut donc tout recupérer et ensuite redirigé :

www/httpdocs/.htaccess

   RewriteEngine on
   RewriteBase /
   RewriteRule    (.*) redir.php?$1 [QSA,L]

www/httpdocs/redir.php

1){ $page .= $a.’&’; } $i++; } header(‘Location: ‘.$page); ?>

NoScale for full flash website

Quentin — Mon, 17 May 2010 18:26:04 +0000

How configure it: Comment le configurer:

stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.BOTTOM;

StageAlign.TOP	Top	Center
StageAlign.BOTTOM	Bottom	Center
StageAlign.LEFT	Center	Left
StageAlign.RIGHT	Center	Right
StageAlign.TOP_LEFT	Top	Left
StageAlign.TOP_RIGHT	Top	Right
StageAlign.BOTTOM_LEFT	Bottom	Left
StageAlign.BOTTOM_RIGHT Nothing	Bottom Center	Right Center

De plus il faut remplacé les valeurs width et height à 100% partout dans le fichier .html où est intégré le .swf. Moreover you have to replace all width and height value to “100%” in the .html file.

[Qt] Choose the language

Quentin — Fri, 07 May 2010 12:38:44 +0000

It’s a good thing to ask for the language at the first launch of the software because it allows the user to choose even if his language isn’t available (Qt example doesn’t do that).

#include <QTranslator>
#include <QSettings>
#include <QInputDialog>

void setLang(QApplication& app, const QString& idl){
        qWarning(QString("Lang is %1 (lang_%1)").arg(idl).toLatin1());

        QTranslator* translator = new QTranslator();
        translator->load("SepMin_" + idl,":/Translations/release");
        app.installTranslator(translator);
}

void manageLang(QApplication& app){
        QSettings settings("Bramas.fr", "AllSepMin");
        int lang = settings.value("lang", -1).toInt();
        if( lang == -1){
                QStringList languages;
                languages << "English" << "Francais";
                lang = languages.indexOf(QInputDialog::getItem(0, "Preference", "Choose your language ?", languages, 0, false));
                if(lang == -1){
                        lang = 0;
                }
                settings.setValue("lang", lang);
        }

        switch(lang){
                case 0:
                        setLang(app,"en");
                        break;
                case 1:
                        setLang(app,"fr");
                        break;
        }
}
int main(int argc, char *argv[])
{

    QApplication a(argc, argv);

    manageLang(a);

    MainWindow w;
    w.show();
    return a.exec();

Users having access to multiple folders in FileZilla Server

Quentin — Tue, 16 Mar 2010 17:35:34 +0000

There is a little stuff if you want to add a user having access to multiple folders in FileZilla Serve.

Off course you don’t want to add for each folder a new user, so let’s do this.

You have to create a new alias, click right on the folder which is not the home directory, and select “Edit aliases..”, and fill in /Folder . Now this folder is accessible by the home directory as a folder named Folder, great!!
