How to create a download button?

printec

Hi,

Back to this XeroConnect module. I have found some code to generate x509 keys. However once PHP generates these keys and stores them in the modules data directory I need a way to download them. I have added a button but don't know how to connect it up within your framework to download a file from module data directory. This is what my form looks like so far.

Screenshot of XeroConnect

and the code so far...

<?php

//ini_set( 'error_reporting', E_ALL );

//ini_set( 'display_errors', true );

defined("_VALID_ACCESS") || die('Direct access forbidden'); // - security feature

//require_once 'x509_keys.php';

class Custom_XeroConnect extends Module { // - notice how the class name represents its path

  public function body() { // - modules main code

    //print('Xero Connect');

    $form = $this->init_module('Libs/QuickForm');

		$form->addElement('header', 'title', __('Xero Connect'));

    $form->addElement('text','consumer_key',__('Consumer Key'));

    $form->addElement('text','secret_key',__('Secret Key'));

    $form->addElement('header', 'subtitle1', __('Certificates'));

    $form->addElement('button', 'download_btn', __('Download public certificate'), $form->get_submit_form_href());

    $form->addElement('button', 'cert_btn', __('Generate Certificate'), $form->get_submit_form_href());

    $form->addElement('submit', 'button', __('Save'), $form->get_submit_form_href());

//echo realpath(dirname(__FILE__));

    if ($form->validate()) {

      $values = $form->exportValues();

      var_dump($values);

      $local = $this->get_data_dir();

      var_dump($local);

    }

    $form->display();

  }

  public function get_x509_keys() {

  }



}

?>

To download files and authorize user you have to create separate script. For instance download.php
Script should be something like this:



<?php

if(!isset($_REQUEST['file'])) // pass file type if you wan't to handle more file types: public cert, private key

	die('Invalid usage');

$file = $_REQUEST['file'];

// code required to load EPESI runtime

define('CID', false);

define('READ_ONLY_SESSION',true);

require_once('../../../include.php');

ModuleManager::load_modules();

//

if(!Acl::i_am_sa()) // only allow for super admin

	die('Permission denied');

$filename = '';

if ($file == 'pub') $filename = ' ... '; // just file name

if ($file == 'priv') $filename = ' ... ';

if (!$filename) die('Invalid file');

$file_path = 'data/Custom_Xero/' . $filename; //real path to file relative to EPESI root

if (!file_exists($file_path)) die('Invalid file');

$buffer = file_get_contents($file_path);

header('Content-Type: xxx '); // fill proper content type

header('Content-Length: '.strlen($buffer));

header('Content-disposition: filename="'.$filename.'"');

echo $buffer;

Something like this. I've made this script specially for you mixing those files:
modules/Libs/TCPDF/download.php
modules/Utils/Attachment/get.php
