Example virtual host and .htaccess configuration for Zend application on OSX Lion

Posted by on August 3, 2012 No comments

I usually work with the backend of web applications so I do not get enough training in setting up virtual hosts, so I thought I better put an example up here. At least to have something to start with.

I use the built in apache server on OSX and I usually put my virtual hosts in the <username>.conf (/private/etc/apache2/users/<username>.conf) where <username> is simply your username 🙂

Example:

<VirtualHost *:80>
        ServerName my.zendapp.com
        DocumentRoot "/Users/<username>/Sites/myzendapp"
        ServerAdmin admin@my.zendapp.com

        <Directory "/Users/<username>/Sites/myzendapp">
                Options Indexes FollowSymLinks
                AllowOverride FileInfo
                Order allow,deny
                Allow from all
        </Directory>

</VirtualHost>

To get my.zendapp.com to work we need to put an entry in the hosts file like this:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost 
fe80::1%lo0     localhost
127.0.0.1       my.zendapp.com

To reach your new zendapp go to: http://my.zendapp.com/public

If you want to use http://my.zendapp.com instead just add the public part to the DocumentRoot:

DocumentRoot "/Users/<username>/Sites/myzendapp/public"
ServerAdmin admin@my.zendapp.com

and the Directory:

<Directory "/Users/<username>/Sites/myzendapp/public">
                Options Indexes FollowSymLinks


NOTE! Depending on your choice in urls you may need to change the .htaccess (/Users/<username>/Sites/myzendapp/public/.htaccess) file accordingly:

For long url (http://my.zendapp.com/public):

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ /public/index.php [NC,L]

For short url (http://my.zendapp.com):

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ /index.php [NC,L]

Tested on OSX 10.7.4 and Zend Framework 1.10.8

Zend_Db syntax cheat sheet

Posted by on July 9, 2012 No comments

A small cheat sheet with simple examples for the Zend_Db syntax in Zend Framework. A smooth way to write sql that will work on many different databases

Connect to database

$db = Zend_Db::factory('Pdo_Mysql', array(
    'host'     => '127.0.0.1',
    'username' => 'myUser',
    'password' => 'myPassword',
    'dbname'   => 'myDatabase'
));

SELECT statement
eg.

SELECT fname, course, grade FROM students 
   WHERE student_id = {$student_id} ORDER BY grade DESC

is written in Zend_Db syntax like this:

$db->select()
  ->from('students', array('fname', 'course', 'grade'))
  ->where('student_id = ?', $student_id)
  ->order('grade DESC');

If you want to fetch all columns (*), just remove the array(‘name’,…) in the from function

INSERT statement
eg.

INSERT INTO students(id, email, passwrd, fname, address, active) 
   VALUES (id + 1, '{$email}', '{$passwrd}', '{$fname}', '{$address}', 1);

Zend_Db syntax:

$student = array( 'id' => new Zend_Db_Expr('id + 1'),
                  'email' => $email,
		          'passwrd' => $passwrd,
		          'fname' => $fname,
		          'address' => $address,
		          'active' => '1');

$db->insert('students', $student);

UPDATE statement
eq.

UPDATE students
   SET passwrd = '{$passwrd}',
       fname = '{$fname}',
       address = '{$address}',
       active = 1
WHERE id = '{$student_id}'

Zend_Db syntax:

$student = array('passwrd' => $passwrd,
                 'fname' => $fname,
                 'address' => $address,
                 'active' => '1');

$db->update('students', $student, 'id = ' . $student_id);

DELETE statement
eq.

DELETE FROM students WHERE id = '{$student_id}'

Zend_Db syntax:

$db->delete('students', 'id = ' . $student_id);

Tested in Zend Framework 1.10.8 on OSX 10.7.4

Setup SQLite in Zend Framework

Posted by on December 19, 2011 No comments

Like many things in Zend Framework this is very simple. I will here show how I usually do.

First we set the required parameters in application.ini:

[production]
...
;Setup database (SQLITE)
resources.db.adapter = "PDO_SQLITE"
resources.db.params.dbname = APPLICATION_PATH "/../db/basic.db"
...

This tells Zend that we will be using a SQLite database (PDO_SQLITE) and then also the path to the SQLite db file (basic.db)

For easy access we will now add the database handle to the Zend registry:
Bootstrap.php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap {
 ...
    protected function _initDbAdapter() {
        $this->bootstrap('db');
        $db = $this->getResource('db');
        Zend_Registry::set('db' , $db);
    }
 ...
}

Then whenever we need to use the database we collect if from the Registry 

// Get SQLite db handle from the registry
$db = Zend_Registry::get('db');

// Use the database
$resultset = $db->fetchAll("SELECT id, name FROM projects");

Done!

Tested on Mac OSX 10.6.8 and Zend Framework 1.10.8
