How to use regex route rewrite in zf1

Just add construction like this to your config file:

resources.router.routes.exhange.type = "Zend_Controller_Router_Route_Regex"
resources.router.routes.exhange.route = "([a-zA-Z0-9]+)-to-([a-zA-Z0-9]+).html"
resources.router.routes.exhange.defaults.module = default
resources.router.routes.exhange.defaults.controller = index
resources.router.routes.exhange.defaults.action = exchange
resources.router.routes.exhange.map.1 = "from"
resources.router.routes.exhange.map.2 = "to"

Then you will be able to use links like: /one-to-two.html, where $_GET['from'] will be "one" and $_GET['to'] - "two".

How to group WHERE clause in zf1

$db = $this->getAdapter();
$select = $db->select();
$select->from($this->_name);

$select->where('ip = ?', '120.0.0.1');

Access control list (ACL) in zend framework 1

For implementing ACL you have to create class, in which will be created roles, resources and settings permissions. For this reason add to application/configs/application.ini:

autoloadernamespaces.app = "App_"

And create file library/App/Acl.php:

/**
 * Class App_Acl
 */
class App_Acl extends Zend_Acl
{
    function __construct()
    {
        $defaultResource = new Zend_Acl_Resource('default');
        $adminResource = new Zend_Acl_Resource('admin');

        $this->addResource($adminResource);
        $this->addResource($defaultResource);

        // guest/client resources
        $this->addResource(new Zend_Acl_Resource('index'), $defaultResource);
        $this->addResource(new Zend_Acl_Resource('payment'), $defaultResource);
        $this->addResource(new Zend_Acl_Resource('panel'), $defaultResource);
        $this->addResource(new Zend_Acl_Resource('user'), $defaultResource);

        // admin resources
        $this->addResource(new Zend_Acl_Resource('admin_user'), $adminResource);
        $this->addResource(new Zend_Acl_Resource('admin_exchange'), $adminResource);
        $this->addResource(new Zend_Acl_Resource('admin_rate'), $adminResource);
        $this->addResource(new Zend_Acl_Resource('admin_eps'), $adminResource);
        $this->addResource(new Zend_Acl_Resource('admin_page'), $adminResource);

        $this->addRole(new Zend_Acl_Role(App_Acl_Roles::GUEST));
        $this->addRole(new Zend_Acl_Role(App_Acl_Roles::CLIENT), App_Acl_Roles::GUEST);
        $this->addRole(new Zend_Acl_Role(App_Acl_Roles::ADMIN), App_Acl_Roles::CLIENT);

        $this->deny();

        $this->allow(App_Acl_Roles::GUEST, 'index');
        $this->allow(App_Acl_Roles::GUEST, 'payment');
        $this->allow(App_Acl_Roles::CLIENT, 'user');
        $this->allow(App_Acl_Roles::CLIENT, 'panel');

        // Allow all to administrator
        $this->allow(App_Acl_Roles::ADMIN);
    }

    /**
     * Check if user has permission to the requested resource
     *
     * @param null $resource
     * @param null $privilege
     *
     * @return bool Return true if user has permission
     */
    public static function checkPermissions($resource = null, $privilege = null)
    {
        $acl = new App_Acl();

        $auth = Zend_Auth::getInstance()->getIdentity();

        $role = App_Acl_Roles::GUEST;

        if (isset($auth->role) && $auth->role) {
            $role = $auth->role;
        }

        return $acl->isAllowed($role, $resource, $privilege);
    }
}

Note: your auth instance must contains 'role' property.
Then create file library/App/Acl/Roles.php:

/**
 * Class App_Acl_Roles
 */
class App_Acl_Roles
{
    const ADMIN = 'admin';
    const CLIENT = 'client';
    const GUEST = 'guest';
}

From this moment you can add to your controller:

public function preDispatch()
{
  parent::preDispatch();

  if (!App_Acl::checkPermissions($this->getRequest()->getModuleName())) {
      $this->redirect('/login');
  }
}

And if user doesn't have permissions to the controller - it will be redirected to the login page or whatever you want.

Writing errors/exceptions to a log file in zend framework 1

Add to application.ini

resources.log.stream.writerName = "Stream"
resources.log.stream.writerParams.stream = APPLICATION_PATH "/data/logs/application.log"
resources.log.stream.writerParams.mode = "a"
resources.log.stream.filterName = "Priority"
resources.log.stream.filterParams.priority = 5

Add method to application/Bootstrap.php:

/**
* Error handler
*
* @param $errno
* @param $errstr
* @param $errfile
* @param $errline
*
* @throws ErrorException
*/
public function exceptionErrorHandler($errno, $errstr, $errfile, $errline)
{
  throw new ErrorException($errstr, $errno, 0, $errfile, $errline);
}

and to constructor in the same file:

set_error_handler([$this, 'exceptionErrorHandler']);

Then in application/controllers/ErrorController.php. Find method "errorAction" and replace:

$log->log($this->view->message, $priority, $errors->exception);
$log->log('Request Parameters', $priority, $errors->request->getParams());

with

$logMessage = $errors->exception->getMessage() . PHP_EOL .
    $errors->exception->getTraceAsString() . PHP_EOL .
    'Request Parameters:' . PHP_EOL .
    var_export($errors->request->getParams(), true) . PHP_EOL .
    str_repeat('-', 50) . PHP_EOL;
$log->log($logMessage, $priority, $errors->exception);

And in the same file change $priority = Zend_Log::CRIT; to $priority = Zend_Log::NOTICE;
Don't forget to create application/data/logs/application.log and set writing permissions to it. Exceptions will be written to this file.

How to enable ssl/https in zend framework 1

Add this to application/Bootstrap.php:

protected function _initForceSSL() {
    if($_SERVER['SERVER_PORT'] != '443') {
        header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
        exit();
    }
}

Localization in zend framework 1

In zf1 you can localize text, date, numbers and many other.
First of all you have to create folders for each locale. E.g. for russian locale: application/languages/ru_RU/, where ru - locale, RU - country.
Then you can create files with translations. As example create FormLabel.csv in your ru_RU folder:

"Login:";"Логин:"
"Password:";"Пароль:"
"Password confirmation:";"Подтверждение пароля:"
"First name:";"Имя:"
"Last name:";"Фамилия:"

Also you need to add locale initialization to your bootstrap file (application/Bootstrap.php):

protected function _initTranslate()
{
  $locale = new Zend_Locale('ru_RU');
  $registry = Zend_Registry::getInstance();
  $registry->set('Zend_Locale', $locale);

  $translate = new Zend_Translate(Zend_Translate::AN_CSV, APPLICATION_PATH . '/languages', null,
      ['scan' => Zend_Translate::LOCALE_DIRECTORY]);

  $registry->set('Zend_Translate', $translate);
}

From this moment localization will be enabled and if you create form with label "Login:" it'll be displayed as "Логин:".
But if you want to handy translate text in your templates add this function

function __()
{
    return Zend_Registry::get('Zend_Translate')->translate(func_get_args());
}

after

require_once 'Zend/Application.php';

to public/index.php.
And then in your phtml you can translate text:

<?= __('Password:') ?>

Creating pagination in zf1

For creating pagination in zend framework 1 you have to perform several steps:
1) Set up pagination template.
Create file application/views/scripts/pagination.phtml:

<div>
    <ul class="pagination">
        <?php if (isset($this->previous)): ?>
            <li><a href="<?= $this->url(array('page' => $this->first)); ?>"><span>&laquo;</span></a>
        <?php else: ?>
            <li class="disabled"><span>&laquo;</span></li>
        <?php endif; ?>

        <?php if (isset($this->previous)): ?>
            <li><a href="<?= $this->url(array('page' => $this->previous)); ?>">&larr;</a></li>
        <?php else: ?>
            <li class="disabled"><span>&larr;</span></li>
        <?php endif; ?>
        <!-- Numbered page links -->
        <?php foreach ($this->pagesInRange as $page): ?>
            <?php if ($page != $this->current): ?>
                <li><a href="<?= $this->url(array('page' => $page)); ?>"><?= $page; ?></a></li>
            <?php else: ?>
                <li class="active"><span><?= $page; ?></span></li>
            <?php endif; ?>
        <?php endforeach; ?>
        <!-- Next page link -->
        <?php if (isset($this->next)): ?>
            <li><a href="<?= $this->url(array('page' => $this->next)); ?>">&rarr;</a></li>
        <?php else: ?>
            <li class="disabled"><span>&rarr;</span></li>
        <?php endif; ?>
        <!-- Last page link -->
        <?php if (isset($this->next)): ?>
            <li><a href="<?= $this->url(array('page' => $this->last)); ?>">&raquo;</a></li>
        <?php else: ?>
            <li class="disabled"><span>&raquo;</span></li>
        <?php endif; ?>
    </ul>
</div>

2) Create an instance of Zend_Paginator with paginator adapter.
For instance, you can create method getPaginator in your table model:

/**
 * Class Application_Model_DbTable_Task
 */
class Application_Model_DbTable_Task extends Zend_Db_Table_Abstract
{
    protected $_name = 'task';
    protected $_rowClass = 'Application_Model_Task';

    public function getPaginator(array $where = [])
    {
        $db = $this->getAdapter();
        $select = $db->select();
        $select->from($this->_name);

        foreach ($where as $key => $value) {
            $select->where($key, $value);
        }

        $select->order('created_at DESC');

        $adapter = new Zend_Paginator_Adapter_DbSelect($select);
        $paginator = new Zend_Paginator($adapter);

        return $paginator;
    }
}

and in your controller:

$user = Application_Model_User::getCurrent();
$tableTask = new Application_Model_DbTable_Task();
$paginator = $tableTask->getPaginator(['id_user = ?' => $user->id]);

$page = $this->getRequest()->getParam('page', 1);
$paginator->setCurrentPageNumber($page);
$config = $this->getInvokeArg('bootstrap')->getOptions();
$paginator->setItemCountPerPage($config['pagination']['per_page']);

$this->view->paginator = $paginator;

3) Configure pagination in settings file and in your bootstrap.
Add to application.ini:

pagination.per_page = 10

and in bootstrap:

protected function _initPagination()
{
    Zend_Paginator::setDefaultScrollingStyle('Sliding');
    Zend_View_Helper_PaginationControl::setDefaultViewPartial(
        'pagination.phtml'
    );
}

4) Print pagination html.
Add in view template:

<?php if (count($this->paginator)): ?>
    <?php foreach ($this->paginator as $item): ?>
        <div class="item">
            <?= $item['value'] ?> (<?= $item['state'] ?>)
        </div>
    <?php endforeach; ?>
<?php else: ?>
    <div class="empty">
        Nothing is found.
    </div>
<?php endif; ?>

<?= $this->paginator ?> 

where $item - a row from db
