public static function listenToPostConfigure($event)
{
  $form            = $event->getSubject();
  $widgetSchema    = $form->getWidgetSchema();
  $validatorSchema = $form->getValidatorSchema();
 
  $fields = $form->getFormFieldSchema()->getWidget()->getFields();
  foreach ($fields as $key => $object)
  {
    $label = $form->getFormFieldSchema()->offsetGet($key)->renderLabelName();
    if (isset($validatorSchema[$key]) and $validatorSchema[$key]->getOption('required') == true)
    {
      $title  = $key . '_field_is_required';
      $label .= '<sup>getFormFormatter()->translate($title) . '">*</sup>';
    }
    $widgetSchema->setLabel($key, $label);
  }
}

Add a listener to the form.post_configure event with your function

$dispatcher = $this->getEventDispatcher();
$dispatcher->connect('form.post_configure', array('BaseForm', 'listenToPostConfigure'));

Change from Doctrine to Doctrine_Core with one command

To change all your code from Doctrine to Doctrine_Core you can use the following command

1

for fl in `find apps/ config/ lib/ test/ -name *.php`; do mv $fl $fl.old; sed 's/Doctrine::/Doctrine_Core::/g' $fl.old &gt; $fl; rm -f $fl.old; done

When you have a plugin you can use this command

1

for fl in `find . -name *.php`; do mv $fl $fl.old; sed 's/Doctrine::/Doctrine_Core::/g' $fl.old &gt; $fl; rm -f $fl.old; done

How can i run multiple instances of memcached on one server?

Problem

I need more then one memcached server.

Solution

Virtual machine

I can build for each memcached server a virtal machine.

Problems

  • more memory (system+memcached)
  • one ip address for each instance
  • more work

Multiple instances via ports

For this it needs to patch the init.d and start-memcached scripts to run multiple instances.

After the patch it search for configuration files that match the following pattern /etc/memcached_*.conf. When it found no file it use the /etc/memcached.conf configuration file. So it breaks no backward compatibility.

When you want to create 2 memached instances copy the configuration file and change the port, memory …

cp /etc/memcached.conf /etc/memcached_myserver_1.conf
cp /etc/memcached.conf /etc/memcached_myserver_2.conf

Commands

start all servers

/etc/init.d/memcached start

start only a specific server

/etc/init.d/memcached start myserver_1

stop all servers

/etc/init.d/memcached stop

stop only a specific server

/etc/init.d/memcached stop myserver_1

The patches

How can i use embed forms or simgle form fields depend on a form field?

You have a register form with a field account_type and two embed forms Company and Address.

You want remove the embed Company form, when the field account_type is sfGuardUserProfile::TYPE_PRIVATE otherwise you want remove the embed Address form.

The solution is to override the bind method in your form.

  {
    // unset request param and validator
    if($taintedValues['account_type'] == sfGuardUserProfile::TYPE_PRIVATE)
    {
      unset(
        $taintedValues['Company'],
        $this->validatorSchema['Company']
      );
    }
    else
    {
      unset(
        $taintedValues['Address'],
        $this->validatorSchema['Address']
      );
    }
 
    parent::bind($taintedValues, $taintedFiles);
