How do I call a custom class in the cakephp framework, need some light

bluecake · May 11, 2010

Guys I am abit stuck here.. I have a class called curl() and a function called get_lat_long($postcode,$domain=null) that uses the class curl. But I don't know how to call the "curl class" and run the function get_lat_long() in the controller file in the cakePHP framework. So for example, how do I run that get_lat_long() in the posts_controller.php file in the controllers folder of the framework.

Here is the code for the curl() class:

/** 
* The curl class
*/    
class curl {

    /** 
    * COnstructor
    */    
   function  __construct() {
    

        
    }

    function init_curl($ch,$url,$postfields=null,$follow=null,$cookie=null,$referer=null) {
        
        // Set url
        curl_setopt($ch, CURLOPT_URL, $url);
        
        // Enable Post
        if($postfields) {
            curl_setopt ($ch, CURLOPT_POST, 1);
            curl_setopt ($ch, CURLOPT_POSTFIELDS, $postfields);
        }
        
        if($follow) {
        curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1 );         
        }
                
        if($referer) {
        curl_setopt($ch, CURLOPT_REFERER, $referer);
        }
                        
        //Enable SSL
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        
    
        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)');
        
        //Return results as string
        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
                
        return $ch;
    
    } // end function
    

    /*
    Grabs a page
    */

    function get_page($options) {

    //Set options
    foreach($options AS $key=>$value) {
    $$key = $value;    
    }    
            
        $ch = curl_init();        
        $ch = $this->init_curl($ch,$url,$postfields,$follow,$cookie);
        $page = curl_exec($ch);
        curl_close($ch);
        return $page;
    
    
    }

and here is the function that uses the curl class:

/**
    * Returns a lat / long of a given postcode
    *
    */    
    function get_lat_long($postcode,$domain=null) {
        
        if(!$domain) {
        $domain = "co.uk";
        }

        $url = "http://maps.google." . $domain . "/maps/geo?q=" . urlencode($postcode) . "&output=json&key=ABQIAAAAWjc0ZH2RENLxziofASg9ABQH987j_SlqISv1l93HS7ksPkvN9xRAXjKLSj-Yj2Xw7I6gP3RHQb4UQg";
                        
        $json = $this->curl->get_page(array("url"=>$url));
                        
        $store_data = json_decode(str_replace(""","\"",htmlentities($json))); //Take care of accents
                                
        $lng = $store_data->Placemark[0]->Point->coordinates[0];            
        $lat = $store_data->Placemark[0]->Point->coordinates[1];
        
            //Return
            if($lng && $lat) {
    
                return array('lat'=>$lat,
                             'lng'=>$lng
                             );
                         
            } else {
            
                return false;
            
            }

    }

Could some share some light on how to use the class and the function in cakephp!

Thanks,

Blue..

First locate folder vendors, then in that folder create another folder named curl and in that folder create the file curl.php with your code.

then in your controller do:

App::import('Vendor','curl',array('file'=>'curl/curl.php'));
$curl = new Curl; // creates instance of that class

Now when you want to access functions from that class just do

$curl->get_page(array("url"=>$url)); // from your code

Thanks for your reply but I get the following error

parse error, expecting `T_FUNCTION' in C:\wamp\www\versionOne\controllers\assessors_controller.php on line 7

Here is the code to line 7:

$curl = new Curl; // creates instance of that class

And this is my full code:

<?php
App::import('Vendor','curl',array('file'=>'curl/curl.php'));
class AssessorsController extends AppController {

var $name = 'Assessors';
$curl = new Curl; // creates instance of that class
var $helpers = array('Html', 'Form');



function index() {
	$this->Assessor->recursive = 0;
	$this->set('assessors', $this->paginate());
}

function view($id = null) {
	if (!$id) {
		$this->Session->setFlash(__('Invalid Assessor', true));
		$this->redirect(array('action' => 'index'));
	}
	$this->set('assessor', $this->Assessor->read(null, $id));
}

Do let me know if I have done anything silly! :confused:
