PHP, Comment calculer N jours depuis une date

HiO — Tue, 08 Jun 2010 18:57:37 +0000

J’ai eu besoin de calculer 92 jour depuis le jour J+1, donc voila, le petit algo mignon.

    $month = date('m');
    $year = date('Y');
    $day = date('d', mktime(0, 0, 0, $month, date('d', strtotime("+1 day")), $year));
    if(date('d') == date('t'))
      $month = date('m', strtotime('+1 month'));
    $dateArray = array();
    $dateArray[] = '';  
    for($i = 0,$j = $day; $i < 92; $i++,$j++) {
      $tmp = array();
      if($j > date('t', mktime(0, 0, 0, $month, '01', $year))) {
        $j = 1;
        if($month == 12) {
          $year = date('Y', mktime(0, 0, 0, '01', '01', $year+1));
        }
        $month = date('m', mktime(0, 0, 0, $month+1, '01', $year));
      }
      if(strlen($j) != 2)
        $tmp[] = '0'.$j;
      else
        $tmp[] = $j;
      if(strlen($month) != 2)
        $tmp[] = '0'.$month;
      else
        $tmp[] = $month;
      $tmp[] = $year;
      $dateArray[] = implode('-', $tmp);
    }

ce qui donne une fois passer a un widget symfony qui va bien

$this->widgetSchema['date_demarage'] = new sfWidgetFormSelect(array('label' => 'Date de démarrage',
                                                                    'choices' => array_combine($dateArray, $dateArray)
                                                                    ));

PHP Symfony, exemple d’utilisation de widget et validateur

HiO — Fri, 16 Apr 2010 12:53:59 +0000

Voici des exemples d’utilisation des widgets et des validateurs symfony, liste mise a jour au fur et a mesure de mes besoins ^^

Widgets

sfWidgetFormDoctrineChoice

$this->widgetSchema['cat_id'] = new sfWidgetFormDoctrineChoice(array('label' => 'Category',
                                                                      'model' => 'hosts_categories',
                                                                      'add_empty' => true));

sfWidgetFormInputPassword

$this->widgetSchema['password'] = new sfWidgetFormInputPassword();

Validateurs

sfValidatorRegex

$this->validatorSchema['intervalle'] = new sfValidatorRegex(array('pattern' => '/^[0-9]{1}[i,m,d]{1}$/'));

sfValidatorOr

$this->validatorSchema['intervalle'] = new sfValidatorOr(array(new sfValidatorRegex(array('pattern' => '/^[0-9]{1}[i,m,d]{1}$/')),
                                                                new sfValidatorRegex(array('pattern' => '/^[0-9]{1}[i,m,d]{1};[0-9]{2}h[0-9]{2}$/'))));

sfValidatorAnd

$this->validatorSchema->setPostValidator(new sfValidatorAnd(array(new sfValidatorSchemaCompare('repassword',  sfValidatorSchemaCompare::EQUAL, 'password'),
                                                                  new sfValidatorDoctrineUnique(array('model' => 'sfGuardUser',
                                                                                                      'column' => 'username'), array('invalid' => 'This username already taken.')),
                                                                  new sfValidatorDoctrineUnique(array('model' => 'sfGuardUser',
                                                                                                      'column' => 'email_address'), array('invalid' => 'This email address already taken.'))
                                                                  )));

sfValidatorSchemaCompare

$this->validatorSchema['password'] = new sfValidatorString(array('min_length' => 5, 'max_length' => 15));
$this->validatorSchema['repassword'] = new sfValidatorString(array('required' => true));
$this->validatorSchema->setPostValidator(new sfValidatorSchemaCompare('repassword',  sfValidatorSchemaCompare::EQUAL, 'password'));

PHP Symfony, Comment changer les messages par defaut des validateurs Symfony

Comment faire , quand on veut changer tous les messages par défaut des validateurs Symfony , sans les définir un par un par un bete ‘message’ => ‘mais blublu’ et sans allez les changer directement dans les entrailles de symfony ce qui est mal !!! C’est mal !!!

Et bien comme ça

    sfValidatorBase::setInvalidMessage('Champ invalide');
    sfValidatorBase::setRequiredMessage('Champ obligatoire');
    parent::setup();

Ce qui nous donne dans un vrai bout de php

VentesForm.class.php


class VentesForm extends BaseVentesForm
{
  public function configure()
  {
    sfValidatorBase::setInvalidMessage('Champ invalide');
    sfValidatorBase::setRequiredMessage('Champ obligatoire');
    parent::setup();
    unset($this['created_at'], $this['updated_at'],
          $this['expires_at'], $this['is_active']);
    $this->widgetSchema['uid'] = new sfWidgetFormInput(array('type' => 'hidden', 'is_hidden' => true));
    $this->widgetSchema['civ'] = new sfWidgetFormChoice(array('choices' => array('M.' => 'M.', 'Mme' => 'Mme', 'Mlle' => 'Mlle')));
    $this->widgetSchema['adresse1'] = new sfWidgetFormTextarea();
    $this->widgetSchema['adresse2'] = new sfWidgetFormTextarea();
    $this->widgetSchema['adresse3'] = new sfWidgetFormTextarea();
    $this->validatorSchema['email'] = new sfValidatorEmail(array(), array('invalid' => 'L\'adresse email saisie est incorrecte'));
    $this->widgetSchema->setLabel('numeroabo', 'N°Abonné');
  }
}
