Iankulov Miodrag The Blog

Am pornit de la clasa asta, si am "curatato un pic" dupa bunul meu plac si deasemenea am folosit Zend_Log nu Zend_Mail, ca nu am chef sa primesc 5000 precum ca niste idiotii nu au nimerit un url corect si etc, mai bine frumos totul scris!

Nu stiu daca titlul e prea maret, dar in fine sa va explic repede cum sta situatia.Daca aveti intr-un camp unixtime si vreti sa afisati toate luniile, din db pentru field-ul respectiv si faceti:

SELECT DISTINCT EXTRACT(YEAR_MONTH FROM FROM_UNIXTIME(date)) FROM `posts`

Veti primi un raspuns de genul:200908; well asta e superb, dar daca vreti sa faceti o archive, de genu cum au toate blogurile: August 2009 trebuie sa faceti cateva tricks.

Eu am scris un view helper pentru Zend Framework care face asta, sper sa va fie de folos:

class Zend_View_Helper_DateHelper extends Zend_View_Helper_Abstract
{   
    public function dateHelper($string = false)
    {
        if ($string !== false) {
            $_month = substr($string, -2);
            $_year = substr($string, 0, strlen(date("Y")));
            $months = array('01' => "January",
                            '02' => "February",
                            '03' => "March",
                            '04' => "April",
                            '05' => "May",
                            '06' => "June",
                            '07' => "July",
                            '08' => "August",
                            '09' => "September",
                            '10' => "October",
                            '11' => "Novemeber",
                            '12' => "December");
            return $months[$_month].' '.$_year;
        }else{
            return false;
        }
    }
}

Trebuie doar sa ii dati un string de genu 200908, si va prelucra el totul.Sper ca este cuiva de folos.

Inainte de toate vreau sa spun ca nu voi acoperii prea mult in acest post, decat basics, cum sa setati url-ul, presupun ca deja aveti basics cu Zend_Paginator so:

Ok, url-urile default pt Zend_Paginator sunt: controller/action/page/age, well astazi am avut nevoie de ceva diferit, din moment ce am mai avut m-ai multe pagina-ri pe o pagina.

In controller face-ti normal de exemplu:

    private function showData($_id)
    {
        $data = $this->artists_categories
                     ->select();
        $do = $this->db->fetchAll($data);
       
        if (count($do) > 0) {
            $paginator = Zend_Paginator::factory($do);
            $paginator->setItemCountPerPage(5)
                      ->setPageRange(5)
                      ->setCurrentPageNumber($_id);
            return $paginator;
        }else{
            return false;
        }
    }

In views/scripts/action_name/pag/file_name setati:

<?php if ($this->pageCount): ?>
  <ul class="top pag clearfix">
      <?php if(count($this->pagesInRange) >= 2): ?>
      <li>Go to page:</li>
      <?php endif;?>
<?php if (isset($this->previous)): ?>
      <li><a href="<?= $this->url(array('artists' => 'page', 'id' => $this->previous)); ?>">&laquo; Previous</a> </li>
<?php endif; ?>
<?php if(count($this->pagesInRange) >= 2): ?>
    <?php foreach ($this->pagesInRange as $page): ?>
          <li><a href="<?= $this->url(array('artists' => 'page', 'id' => $page)); ?>" <?php if($page == $this->current): ?>id="selected"<?php endif;?>><?=$page;?></a> </li>
    <?php endforeach; ?>
<?php endif; ?>
<?php if (isset($this->next)): ?>
      <li><a href="<?= $this->url(array('artists' => 'page', 'id' => $this->next)); ?>">Next &raquo;</a></li>
<?php endif; ?>
  </ul>
<?php endif; ?>

Url-ul setat mai sus arata cam asa controller/action/artists/page/id/Id-ul

Sa nu uitati sa setati si route

/* Artists */

$ad->addRoute( 'artists', new Zend_Controller_Router_Route('artists/index/page/artists/id/:id', array('module' => 'admin','controller' => 'artists', 'action' => 'index')) );

Sper sa va fie de folos.

Cred ca este cel mai cool pe care l-am vazut pana acuma, thx to iamntz, font-ul se numeste Inconsolata, m-ai jos aveti si o poza, asa ca bonus de la mine , poate va convingeti asa:

In general la aplicatii mari, esti tampit daca nu faci si un easy debug, ca daca "pusca" ceva sa stii imediat unde sa repari, well solutia e logica: logs, dar cam 90% din mesajele de eroare nu vrei sa fie publice, pentru ca contin prea multe informatii, so daca scrii log-urile de eroare intr-un fisier e cel mai bine, si asta o face Zend_Log si mai bine.

Eu acuma am sa dau doar un exemplu, de genul cum gasiti in documentatie.

$writer = new Zend_Log_Writer_Stream(root.'/logs/logs.ini');
$logger = new Zend_Log($writer);       
$logger->log('Sunt in exstaz', Zend_Log::INFO);

root = path-ul de root al aplicatiei

/logs/logs.ini = folderul/numele fisierului unde se vor scrie datele

Zend_Log::INFO = Prioritate built-in de la ZF, mai jos aveti toate exemplele de prioritati.

EMERG = 0; // Emergency: system is unusable
ALERT = 1; // Alert: action must be taken immediately
CRIT = 2; // Critical: critical conditions
ERR = 3; // Error: error conditions
WARN = 4; // Warning: warning conditions
NOTICE = 5; // Notice: normal but significant condition
INFO = 6; // Informational: informational messages
DEBUG = 7; // Debug: debug messages

Ok, iar in logs.ini errorile vor avea urmatorul format:

2009-07-21T18:56:37+03:00 INFO (6): Sunt in exstaz

Mult noroc la curve!
