This plugin now has the following features;

• Optionally provide a caption message and customise its CSS properties from admin screen
• Works with the existing Media Library
• Uses timthumb.php to dynamically size images
• Multiple galleries can be added without invalidating the HTML markup
• Providing a link from the image is optional

The plugin will appear on wordpress.org shortly, but if you want to get you hands on version 1.0 early, you can download it from the official project page on Google Code.

Here’s a sample gallery!

$ mount -t cifs [server-address]/MyVolume /mnt/cifs -o username=[username],password=[password]

The volume will then be found at /mnt/cifs.

You can obtain the latest version of this plugin by visiting the plugin page on wordpress.org or by using your WordPress admin area.

Once installed, go to your admin area > Media > WPS3Slider where you can start creating your galleries. Before you install, make sure the temp, cache and uploads folders are read, write and executable by the server.

chmod 777 {temp,cache,uploads}

To insert a gallery in a post, click on the pictures icon above the media menu above the TinyMCE editor and select the gallery you want. This will then render you the shortcode to use within the post/page. If you want to place a gallery within your template files, you can simply use the do_shortcode method.

do_shortcode('[wps3 id="5"]');

If you find any issues with the plugin, please report them to the project on google code.

Enjoy.

In your main.php config file, you may already have a db component set up by default.

//.. main.php
'db'=>array(
	'connectionString' => 'mysql:host=localhost;dbname=testdrive',
	'emulatePrepare' => true,
	'username' => 'root',
	'password' => 'password',
	'charset' => 'utf8',
),

This will be enabled by default. Now, if you want to enable another connection component, simply add another CDbConnection component and give it a different name.

//.. main.php
'db'=>array(
	'connectionString' => 'mysql:host=localhost;dbname=testdrive',
	'emulatePrepare' => true,
	'username' => 'root',
	'password' => 'password',
	'charset' => 'utf8',
),
'db2'=>array(
        'class'  => 'CDbConnection',
	'connectionString' => 'mysql:host=localhost;dbname=database2',
	'emulatePrepare' => true,
	'username' => 'root',
	'password' => 'password',
	'charset' => 'utf8',
),

Now, in your models you can pass the connection instance using getDbConnection()

class DbTable extends CActiveRecord
{
     public static function model($className=__CLASS__)
    {
        return parent::model($className);
    }

    public function getDbConnection()
    {
        return Yii::app()->db2; // select the connection you want
    }
//.. etc

Using this technique you can have your model classes connect to numerous databases.

Enjoy

The in built contact page features field verification and csrf security prevention.

You can download or clone a copy of the theme by visiting the Git Repo at GitHub.

An example

We’ll create two tables, a users and account table. The account table holds account names (e.g. Guest, Admin, Super Admin) and the users table contains one foreign key that relates to the account type.

The structure looks like this;

And here’s some data that we’ll work with…

Now to perform a simple join of these two tables, we could use…

This simple query will return all records but using this as a base we can further customise our query to make it more useful. If we wanted to find out all users who have Admin accounts we’d use this statement.

SELECT * FROM users u LEFT JOIN accounts a ON u.account_type = a.id WHERE a.name = 'Admin'

// or we could use the ID from the accounts table

SELECT * FROM users u LEFT JOIN accounts a ON u.account_type = a.id WHERE a.id = 2

A note on usage

This is MySQL join in its most simplest terms. You can join multiple tables providing you database design allows it. So with that cleared up, if you are not already using joins in your queries, start using them and cut down on the number of transactions you make…it’ll also make your life a lot easier retrieving data.

function geoRadius($lat, $lng, $rad, $kilometeres = FALSE, $out = 'OBJ')
	{
		$radius = ($kilometers) ? ($rad * 0.621371192) : $rad;

		(float)$dpmLAT = 1 / 69.1703234283616; 

		// Latitude calculation
		(float)$usrRLAT = $dpmLAT * $radius;
		(float)$latMIN = $lat - $usrRLAT;
		(float)$latMAX = $lat + $usrRLAT;

		// Longitude calculation
		(float)$mpdLON = 69.1703234283616 * cos($lat * (pi/180));
		(float)$dpmLON = 1 / $mpdLON; // degrees per mile longintude
		$usrRLON = $dpmLON * $radius;
		$lonMIN = $lng - $usrRLON;
		$lonMAX = $lng + $usrRLON;

		$output = array("lonMIN" => $lonMIN, "lonMAX" => $lonMAX, "latMIN" => $latMIN, "latMAX" => $latMAX);
		return ($out == 'OBJ') ? (object)$output : $output;
	}

Okay, so how do you use it? Well, the first two paramaters are the Latitude and Longitude of your origin. The third is the radius ammount. If you want to calculate it based on kilometers (default is in miles), enter a boolean value of TRUE for the fourth parameter. The last paramter specifices the output method, by default it will return an object, enter anything other that OBJ here will return an associative array.

So, once we’ve done that what do we have? You will then have 4 variables to use, each of them minimum and maximum values of Latitude and Longitude. This is how you could use the output of this function to query a database that contains geo data.

$radius = geoRadius(53.741690, -2.397750, 48.28032);
$sql = "SELECT * FROM `mytable` WHERE `latitude` BETWEEN {$radius->latMIN} AND {$radius->latMAX} AND `longitude` BETWEEN {$radius->lonMIN} AND {$radius->lonMAX}";

The ‘page.php’ file displays your generic page content using this template. You could customise this page to make it look as you want and set it as the home page in the WordPress admin screen. But what happens if we want to create a contact form section? or maybe a one off page that contains some bespoke code? This is how you do it…

In your theme folder, create a new file. In this example, I’ll call it custom.php. Now insert the following code to it.

<?php
/*
Template Name: Custom Page Layout
*/
get_header(); ?>;

// enter your code here

<?php get_footer(); ?>

Now with that, create a new page in the admin section and on the right where it says “Attributes”, select the template name you wrote in the custom.php (Custom Page Layout in this case).

Easy

Connect via SSH and login to mysql…

# mysql -u root -p

// now grant access for the root account
mysql > GRANT USAGE ON *.* to root@'%' IDENTIFIED BY '[password]';
mysql > FLUSH PRIVILEGES;

Change [password] to whatever the password is for the root account and include the single quotes (‘). The % sign means it will accept connections from this account on all IP addresses. You could if you wanted, choose a specific IP here.

You’ll now be able to login remotely.
