• CakePHP 3.x

Installation

Table entry

Add the fields (choose your names, or use the default 'latitude' and 'longitude'). I suggest to use the FLOAT(10,6). Note that, if you change the field names, you must provide them in the plugin configuration.

Setting up the code

Add in config/bootstrap.php the line

Plugin::load('Gps');

and in src/Model/Table/YourModelTable.php the lines

class ArticlesTable extends Table
{
    public function initialize(array $config)
    {
    	...
        $this->addBehavior('Gps.Gps');
        ...
    }
}

You can also provide a configuration with the plugin, extending this lines:

class ArticlesTable extends Table
{
    public function initialize(array $config)
    {
    	...
        $this->addBehavior('Gps.Gps',[
        	'radius'=>6896000000.231,
        	'fields'=>[
        		'latitude'=>'lat',
        		'longitude'=>'lon'
        	]
        ]);
        ...
    }
}

For example, in this configuration, we're informing the plugin that the fields in the table will be of names 'lat' for latitude, and 'lon' for longitude. The Earth radius will be of 6896000000.231 km.

Usage

in src/Controller/YourModelController, for example, in a nearBy action, you could have

public function nearBy(){
	$yourmodel = $this->YourModel->find('near',['gps'=>$this->request->query]);
	$this->set(compact('yourmodel'));
	$this->set('_serialize',['yourmodel']);
}

and so the conditions will be the ones urlencoded:

http://yourdomain.com/youmodel/near-by.json?latitude=43.2&longitude=24.356&radius=20000

With this url we're telling ours API software to take the objects in a square with center in 43.2,24.35 and side of 20000 meters
