Zend - Example For Using Lucene

Zend - Lucene Search

To create a search application using Zend, you use lucene class:

<?php

require_once "Zend/Search/Lucene.php";

$index = new Zend_Search_Lucene('lola', true);
The above code will create a directory folder for search index. There are five files for it:
1. read.lock.file
2. write.lock.file
3. segments_1
4. segments_2
5. segments_gen

$doc->addField(Zend_Search_Lucene_Field::Keyword('link', '<a href="#">Boo</a>'));
$doc->addField(Zend_Search_Lucene_Field::Text('title', 'Hello World'));
$doc->addField(Zend_Search_Lucene_Field::Unstored('contents', 'This is description'));
$index->addDocument($doc);
$index->commit();
echo $index->count()." Documents indexed";

For displaying the result:

$index = new Zend_Search_Lucene('lola');
$query = 'World';
$hits = $index->find($query);
echo "Index contains: ".$index->count()." documents.<br/>";
        echo "Search for: \"".$query."\" returned \"".count($hits)."\" hits";
foreach($hits as $hit){
     echo "<ul>";
     echo "<li>".$hit->link."</li>";
     echo "<li>".$hit->title."</li>";
     echo "<li>".$hit->score."</li>";
      echo "</ul>";
}

Zend - Linking CSS File

You can use either one of this below in your view file:

<?php
    $this->headLink()->appendStylesheet($this->baseUrl().'/css/style.css');
    echo $this->headLink();
?>

Or just use:
<link rel="stylesheet" href="<?php echo $this->baseUrl();?>/css/style.css"/>

Zend - Linking CSS File

Zend - .htaccess

RewriteEngine On
RewriteRule .* index.php

Instead of using the above .htaccess file, use this below one:

RewriteEngine On

RewriteCond $1 !^(index\.php|img/*|js/*|css/*)

RewriteRule ^(.*)$ index.php/$1 [L]

Zend - Built In Helpers

Helper is a function that you call from views.

1. Button Helpers

<?php

    $attr = array(

        'style' => 'background: yellow; border: 1px solid #ccc;',

    );

    echo $this->formButton('init', 'Init', $attr);

?>

Zend - Zend Helper

File: application/views/helpers/HelloHelper.php

<?php

require_once 'Zend/View/Helper/Abstract.php';

class Zend_View_Helper_HelloHelper extends Zend_View_Helper_Abstract{

    function helloHelper(){

        return 'Hello Comes From Helper';

    }

}

?>

Then in the views file, call it using:
<?php echo $this->helloHelper();?>

Zend - Authentication

    public function authAction(){
        $request = $this->getRequest();
        $registry = Zend_Registry::getInstance();
        $auth = Zend_Auth::getInstance();
       
        $db = $registry['db'];
       
        $authAdapter = new Zend_Auth_Adapter_DbTable($db);
        $authAdapter->setTableName('users')
                    ->setIdentityColumn('username')
                    ->setCredentialColumn('password');
                   
        // set the input credential values
        $uname = $request->getParam('username');
        $passwd = $request->getParam('password');
        $authAdapter->setIdentity($uname);
        $authAdapter->setCredential(md5($passwd));
       
        // perform the auth query, saving the result
        $result = $auth->authenticate($authAdapter);
       
        if($result->isValid()){
            $data = $authAdapter->getResultRowObject(null, 'passwd');
            $auth->getStorage()->write($data);
            $this->_redirect('/user/userpage');
        }else{
            $this->_redirect('/user/loginform');
        }
    }
   
    public function userpageAction(){
        $auth = Zend_Auth::getInstance();
       
        if(!$auth->hasIdentity()){
            $this->_redirect('/user/loginform');
        }
       
        $request = $this->getRequest();
        $user = $auth->getIdentity();
        $real_name = $user->real_name;
        $username = $user->username;
        $url = $request->getBaseURL().'/user/logout';
       
        $this->view->assign('username', $real_name);
        $this->view->assign('url', $url);
       
    }
   
    public function logoutAction(){
        $auth = Zend_Auth::getInstance();
        $auth->clearIdentity();
        $this->_redirect('/user');
    }
