Hint/Help on creating a new curl parsing module

[megane72]

Hi, I need some hint or help to progress on my development of a new module.

 

I'm trying to create an admin module that will create a new admin entry that when called will use curl to get informations from some b2b http supplier page and hopefully update the DB with those infos.

 

Now I have succesfully created a new module starting from a skeleton module.

 

It will install and create the new entry in admin menu:

public function install()
{
$tab = new Tab(); 
// Need a foreach for the language
$tab->name[$this->context->language->id] = $this->l('cURL Parsing');
$tab->class_name = 'CurlParsing';
$tab->id_parent = 17;
$tab->module = $this->name;
$tab->add();

// Don't know if the following hooks are needed, I leave those there anyway
if (!parent::install() || 
!$this->registerHook('displayHome') || 
!$this->registerHook('displayHeader') || 
!$this->registerHook('displayBackOfficeHeader') || 
!$this->registerHook('displayAdminHomeQuickLinks'))
return false;
return true;
}

and uninstall clean

public function uninstall()
	{
	
		// Uninstall Tabs
		$tab = new Tab((int)Tab::getIdFromClassName('CurlParsing'));
		$tab->delete();
		
		if (!parent::uninstall())
			return false;
		return true;
	}

it calls correctly the controller from the menu entry

 

/modules/curlparsing/controllers/admin/CurlParsingController.php

<?php



class CurlParsingController extends ModuleAdminController
 
{



public function display()    
    {    
         parent::display();  
	 /* {l s='Hello World' mod='curlparsing'}; */
         /* $contents=$this->get_web_page('http://www.google.com'); */
         /* $this->get_web_page('http://www.google.com'); */
         $this->context->smarty->get_web_page('http://www.google.com');
    }

public function __construct()    
    {    
         parent::__construct();        
    }

public function initContent()    
    {
        parent::initContent();       
        /* $this->setTemplate(_PS_THEME_DIR_.'mypage.tpl');   */
	/* $this->setTemplate(_PS_ROOT_DIR_.'/modules/curlparsing/curlparsing.tpl'); */
	/* $this->context->smarty->createTemplate(_PS_ROOT_DIR_.'/modules/curlparsing/curlparsing.tpl', parent); */

    }
        
public function get_web_page( $url )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "spider", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        CURLOPT_SSL_VERIFYPEER => false     // Disabled SSL Cert checks
    );

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    $header['errno']   = $err;
    $header['errmsg']  = $errmsg;
    $header['content'] = $content;
    return $header;
}
/* $contents=$this->get_web_page('http://www.google.com'); */


 
}

but i'm stuck there, you can notice above my various commented attempts.

 

I don't know how and where to call the function get_web_page in order at least to visualize the remote page as an admin page or to visualize the source of the page, is the same for me.

 

After solving this I will continue implementing auth before calling the page and DB update (but i leave those for future help only if I got stuck again).

 

Please keep in mind that i'm a newbie on php and PS so i could need some basic information.

 

I try to search this info on PS manual and various forums, I learned a lot but not enough...

 

Thank you all in advance.
