Par un détour à Yoda

It's possible, when validating a form, to check if a field is correct dependently of an other field's value.

First, in your configure method, after the declaration of your validators, add :

$this->validatorSchema->setPostValidator(
    new sfValidatorCallback(
        array('callback' => array($this, 'checkRequiredFields'))
    )
);

And create a new method in your form class !

public function checkRequiredFields($validator, $values) {
    $errors = array();
    /**
     * checking if mandatory_field == 3, then other_field must be filled
     */
    if(3 == $values['mandatory_field'] && null == $values['other_field']) {
        $error = new sfValidatorError($validator, 'if you choose the option 3 for mandatory_field, you need to fill the other_field');
        $errors['other_field'] = $error;
        //throw new sfValidatorErrorSchema($validator, array('other_field' => $error));
    } else {
        // nothing to check
    }
 
 
    /**
     * checking if foo is selected, then bar must be filled
     */
    if(1 == $values['foo'] && null == $values['bar']) {
        $error = new sfValidatorError($validator, 'if you check foo, you need to fill bar');
        $errors['bar'] = $error;
    } else {
        // nothing to check
    }
 
    /**
     * more depency checking here
     */
 
    /**
     * if there is errors
     */
    if(count($errors)) {
        throw new sfValidatorErrorSchema($validator, $errors);
    }
    /**
     * dont forget to return values !
     */
    return $values;
}

2010-02-23 Updated: All errors are now returned once. 2010-02-23 Updated: Deleted the commented throw, added another check.

In symfony, it's possible to return a value in your execute() method.

Let's create a test task :

┌─(yoda@box)(09:46:59)
└─(~/var/www/test)-> ./symfony generate:task test
>> task      Creating "/home/yoda/var/www/test.../testTask.class.php" task file

Adding a return value at the end of the method. :

<?php
 
class testTask extends sfBaseTask
{
  protected function configure()
  {
    // // add your own arguments here
    // $this->addArguments(array(
    //   new sfCommandArgument('my_arg', sfCommandArgument::REQUIRED, 'My argument'),
    // ));
 
    $this->addOptions(array(
      new sfCommandOption('application', null, sfCommandOption::PARAMETER_REQUIRED, 'The application name'),
      new sfCommandOption('env', null, sfCommandOption::PARAMETER_REQUIRED, 'The environment', 'dev'),
      new sfCommandOption('connection', null, sfCommandOption::PARAMETER_REQUIRED, 'The connection name', 'doctrine'),
      // add your own options here
    ));
 
    $this->namespace        = '';
    $this->name             = 'test';
    $this->briefDescription = '';
    $this->detailedDescription = <<<EOF
The [test|INFO] task does things.
Call it with:
 
  [php symfony test|INFO]|>
EOF;
  }
 
  protected function execute($arguments = array(), $options = array())
  {
    // initialize the database connection
    $databaseManager = new sfDatabaseManager($this->configuration);
    $connection = $databaseManager->getDatabase($options['connection'] ? $options['connection'] : null)->getConnection();
 
    // add your code here
    return 42;
  }
}

And now, execute the task :

┌─(yoda@box)(09:47:32)
└─(~/var/www/test)-> ./symfony test
┌─(yoda@box)(09:47:40)
└─(~/var/www/test)-> echo $?
42

The return value is correctly returned. Note that without return value, the task simply returns 0.

In the case that an exception occurs, let's see what is returned. I added a dummy exception in the execute method :

<?php
 
class testTask extends sfBaseTask
{
  protected function configure()
  {
    // // add your own arguments here
    // $this->addArguments(array(
    //   new sfCommandArgument('my_arg', sfCommandArgument::REQUIRED, 'My argument'),
    // ));
 
    $this->addOptions(array(
      new sfCommandOption('application', null, sfCommandOption::PARAMETER_REQUIRED, 'The application name'),
      new sfCommandOption('env', null, sfCommandOption::PARAMETER_REQUIRED, 'The environment', 'dev'),
      new sfCommandOption('connection', null, sfCommandOption::PARAMETER_REQUIRED, 'The connection name', 'doctrine'),
      // add your own options here
    ));
 
    $this->namespace        = '';
    $this->name             = 'test';
    $this->briefDescription = '';
    $this->detailedDescription = <<<EOF
The [test|INFO] task does things.
Call it with:
 
  [php symfony test|INFO]|>
EOF;
  }
 
  protected function execute($arguments = array(), $options = array())
  {
    // initialize the database connection
    $databaseManager = new sfDatabaseManager($this->configuration);
    $connection = $databaseManager->getDatabase($options['connection'] ? $options['connection'] : null)->getConnection();
 
    // add your code here
    throw new Exception('foo');
    return 42;
  }
}

┌─(yoda@box)(09:51:37)
└─(~/var/www/test)-> ./symfony test

               
  foo         
               

┌─(yoda@box)(09:51:43)
└─(~/var/www/test)-> echo $?
1

The task returns 1 in case of an exception.

I recently had a problem when loading fixtures in my symfony project. I was loading cities, about 37 000 of them, and the doctrine:data-load was extremly slow (about 5 minutes). I finally found a solution to load an sql dump wihtin a task, using the doctrine/default connection.

With this solution, I reduced the time from minutes to 2 secondes.

<?php
 
class loadALotOfDataTask extends sfBaseTask
{
  protected function configure()
  {
    // // add your own arguments here
    // $this->addArguments(array(
    //   new sfCommandArgument('my_arg', sfCommandArgument::REQUIRED, 'My argument'),
    // ));
 
    $this->addOptions(array(
      new sfCommandOption('application', null, sfCommandOption::PARAMETER_REQUIRED, 'The application name', 'frontend'),
      new sfCommandOption('env', null, sfCommandOption::PARAMETER_REQUIRED, 'The environment', 'dev'),
      new sfCommandOption('connection', null, sfCommandOption::PARAMETER_REQUIRED, 'The connection name', 'doctrine'),
      // add your own options here
    ));
 
    $this->namespace        = '';
    $this->name             = 'loadALotOfData';
    $this->briefDescription = '';
    $this->detailedDescription = <<<EOF
The [loadALotOfData|INFO] task does things.
Call it with:
 
  [php symfony loadALotOfData|INFO]|>
EOF;
  }
 
  protected function execute($arguments = array(), $options = array())
  {
    // initialize the database connection
    $databaseManager = new sfDatabaseManager($this->configuration);
    $connection = $databaseManager->getDatabase($options['connection'] ? $options['connection'] : null)->getConnection();
 
    // add your code here
    $file = '../data/dump.sql';
    if(!file_exists($file)) {
        $this->logSection('File', sprintf('File %s does not exists', $file));
        return;
    }
    // loading the file in the memory. In my case, the file was 
    $data = file_get_contents($file);
    // passing queries to the orm
    $statement = $connection->prepare($data);
    // executing
    $statement->execute();
  }
}

I recently recevied my new Asus eee1005HA-H bough on Materiel.net. Everything seemed fine as there was a Debian project supporting the eee-s. But unfortunately the current installer couldn't support networking devices.

Here is a little tip to display the latest posts of your dotclear blog in your symfony website.

Create a connection

If your blog database is in an other database than symfony's one, you need to create a connection in the /config/databases.yml. Otherwise, skip this step Mine looks like this :

[yml]
dev:
  beta:
    param:
      classname:  DebugPDO

test:
  beta:
    param:
      classname:  DebugPDO

all:
  symfony:
    class:        sfDoctrineDatabase
    param:
      classname:  DoctrinePDO
      dsn:        mysql:dbname=mysymfonydbanem;host=localhost
      username:   mysymfonyusername
      password:   mysymfonypassword
      encoding:   utf8
      persistent: true
      pooling:    true
  blog:
    class:        sfDoctrineDatabase
    param:
      classname:  DoctrinePDO
      dsn:        mysql:dbname=myblogdbname;host=localhost
      username:   myblogusername
      password:   myblogpassword
      encoding:   utf8
      persistent: true
      pooling:    true

Read more about connections.

Create Dotclear models from the database

You must create models from the database to be able to retrieve the posts

$ ./symfony doctrine:build-schema --env=blog
$ ./symfony doctrine:build-model

As you can see, some Dc*.class.php are now created in the /lib/model/doctrine/ folder.

Fetching latests posts

In your controller (actions.class.php), use and customize this request :

public function executeIndex(sfWebRequest $request)
  {
    $this->posts = Doctrine_Query::create()
        ->from('DcPost p')
        ->where('p.post_status = 1')
        ->orderBy('p.post_creadt DESC')
        ->limit(5)
        ->execute();
  }

Displaying posts

<?php foreach($posts as $post) : ?>
  <div class="blog_box">
    <h5><a href="#"><?php echo $post->getPostTitle() ?></a></h5>
    <?php echo __('Posted by') ?> <a href="http://url.to.your.blog/path/index.php?post/<?php echo $post->getPostUrl() ?>"><span><?php echo $post->getDcUser()->getUserDisplayname () ?></span></a> <?php echo __('in') ?> <a href="#"><span><?php echo $post->getDcCategory()->getCatTitle() ?></span></a><br />
    <?php echo substr(strip_tags($post->getRawValue()->getPostContentXhtml()), 0, 40).'...' ?><br />
    <div class="datetime"><?php echo $post->getPostCreadt() ?></div>
  </div>
<?php endforeach; ?>

and that's it, you made it !

PS: This howto is maybe somehow wrong, I made those steps few times before making this working. Feel free to correct.

Update 1 : Added a where clause to select only posts where post_status = 1. Added the link to the post

When your browser is configured to save password fields, it's very easy to reveal that field without knowing the master password (because *of course* you have a master password).

Just use firebug. Load the page, and change change <input type="password" /> by <input type="text" />

I recently installed a fresh debian lenny. To play some music I decided to keep decibel audio player that I already have on my personal pc.

But when I wanted to play some MP3's it kept saying:

** Message: don't know how to handle audio/mpeg, mpegversion=(int)1, layer=(int)3
** Message: don't know how to handle audio/mpeg, mpegversion=(int)1, layer=(int)3
** Message: don't know how to handle audio/mpeg, mpegversion=(int)1, layer=(int)3
** Message: don't know how to handle audio/mpeg, mpegversion=(int)1, layer=(int)3

I finally found why. You just have to install gstreamer0.10-fluendo-mp3

Hope this help

Here is a new version of my plugin.

• Don't show the event if the user is blocked (and the "don't show blocked user notification" config is set
• Added OS Check
• Code cleaning
• Bumped to version 1.4

Thanks to KaKaRoTo for the blocked system.

Récemment, je me suis occupé de la création d'un site web tout joli tout beau, dans lequel les webmasters peuvent composer certaines parties de leur site web via un éditeur online wysiwyg. Mais à certains endroits, j'avais besoin de mettre juste le début du texte suivi des traditionnels 3 petits points.
