How
a web application can be completed without usage of database. Different
web application uses different database. Some uses Mysql, other SQLite,
SQL server and Oracle. One of the nice thing about Zend Framework is
that it support multiple database servers.

 [general]
db.adapter = PDO_MYSQL
db.params.host = localhost
db.params.username = root
db.params.password = 
db.params.dbname = zend_framework

<?php
define('ROOT_DIR', dirname(__FILE__));

set_include_path('.'
. PATH_SEPARATOR . ROOT_DIR . '/library'
. PATH_SEPARATOR . ROOT_DIR . '/application/models'
. PATH_SEPARATOR . ROOT_DIR . '/application/forms'
. PATH_SEPARATOR . get_include_path()
);

require_once "Zend/Loader.php";
Zend_Loader::registerAutoload();

$config = new Zend_Config_Ini(ROOT_DIR.'/application/config.ini', 'general');
$db = Zend_Db::factory($config->db);
Zend_Db_Table::setDefaultAdapter($db);

$frontController = Zend_Controller_Front::getInstance();
$frontController->throwExceptions(true);
$frontController->setControllerDirectory(ROOT_DIR.'/application/controllers');
$frontController->dispatch();
?>

How to create Custom Block?

Following is a simple example of custom block. For more information on blocks in general,
see the Blocks page of the handbook.
Adding A 'Contact Information' Block
A business or support group should always let people know how to contact them. One easy
thing is to include your mailing address on your pages. This is about the easiest kind of
block to start with.
1. Go to Administer>>Site building>>Blocks. It should already be sitting on your default theme, but if not, select the right one.

2. Click on the "Add block" tab.

3. Fill in the "Description" and "Body." Here's a sample body:
Example Organization<br>
The Drupal Cookbook (for beginners) http://drupal.org/book/export/html/120612
19 of 39 25.10.2008 18:42
123 Main St.<br>
Mytown, State Zip<br>
USA<br>
(123) 456-7890

4. Save the block.

5. Now you can "Configure" the block to add the block's title and define it's "Visibility".

6. Follow the Configure link next to the block and enter "Contact Information" as the Block's title.

7. Decide if you want to allow users to turn the block on or off, and, if so, which roles should have that ability. You can leave this with no changes to allow everyone to see it. Then choose which pages it will be shown on; Leave this empty to show the block on all pages.

8. Save the block.

9. Now you're back on the block list. Find the block you just created in the list and choose a "Region". You can use the "Weight" parameter to set its position with in the selected area; again, I like the address at the bottom, so I use a heavier weight.

10. Click on the "Save blocks" button.


and done.

Enjoy Drupaling !

How to create pages for "Page Not Found" and "Access Denied"?

Just go to "Create content" and select "Page." I title them "Access Denied" and "Page Not
Found" but you can call them whatever makes sense to you and your users. When you
submit them, note the node ids. Then go to Administer >> Site Configuration >> Error Reporting  and
enter "node/__" in the appropriate boxes.

Suppose for Access Denied page node id is 8 and I give content as follows:

<p>We're sorry, but you must have permission to view the page you requested.</p>
<p>&nbsp;</p>
<p>If you are already a registered member of this site, please try <a href="user">logging in</a>.</p>
<p>&nbsp;</p>
<p>If you are not a member, you need to <a href="/join_us">join us</a>.</p>
<p>&nbsp;</p>
<p>If you have any questions about our site or group, please feel free to <a href="/contact">contact us</a>.</p>
<p>&nbsp;</p>
<p>--Webmistress</p>


And for Page Not Found page node id is 9 and I give content as follows:

<p>Sorry! The page you were looking for no longer exists. We redesigned our site and many of the pages have
changed.</p>
<p>&nbsp;</p>
<p>If you are unable to find something on our new site or have a question about our site or services feel free to
<a href="/contact">contact us</a>.</p>
<p>&nbsp;</p>
<p>--Webmistress</p>

Now go to Administer >> Site Configuration >> Error Reporting
Here, assign your content node id and Save Configuration.


So, we will give node/8 for Access denied and node/9 for Page Not Found.


Also, you can create page for both :

Page Not Found: page-node-8.tpl.php

Access Denied: page-node-9.tpl.php

Enjoy Drupaling !
