[OpenCart] how to install vQmod in OpenCart ?

Today, I came up here to make some easy pictures to install “vQmod” (Create xml patches for php files without editing the core system source code so called Virtual file modification system) in OpenCart 1.5.5.1

If you don’t know what is vQmod? then please read before we start.

Assume, we have installed a fresh copy of OpenCart 1.5.5.1 in the system

In this tutorial there are more than one way that vQmod can be installed in the opencart system.

Install vQmod in OpenCart manually:

Step-1: For self securitey! Backup or make a duplicate of your existing installed OpenCart files and folders in safe place.

Step-2: Download the latest version of vQMod

Step-3: Extract vqmod-x.x.x-opencart.zip and upload the vqmod folder to root of OpenCart directory.

Step-4: Now, we need to modify two files. One is /index.php and another one is /admin/index.php file

Search,

//File: /index.php 
// Startup
require_once(DIR_SYSTEM . 'startup.php');

// Application Classes
require_once(DIR_SYSTEM . 'library/customer.php');
require_once(DIR_SYSTEM . 'library/currency.php');
require_once(DIR_SYSTEM . 'library/tax.php');
require_once(DIR_SYSTEM . 'library/weight.php');
require_once(DIR_SYSTEM . 'library/length.php');
require_once(DIR_SYSTEM . 'library/cart.php');
require_once(DIR_SYSTEM . 'library/affiliate.php');

Replace with,

// vQmod
require_once('./vqmod/vqmod.php');
VQMod::bootup();

// VQMODDED Startup
require_once(VQMod::modCheck(DIR_SYSTEM . 'startup.php'));

// Application Classes
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/customer.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/currency.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/tax.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/weight.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/length.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/cart.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/affiliate.php'));

and,

Search,

//File: /admin/index.php
// Startup
require_once(DIR_SYSTEM . 'startup.php');

// Application Classes
require_once(DIR_SYSTEM . 'library/currency.php');
require_once(DIR_SYSTEM . 'library/user.php'));
require_once(DIR_SYSTEM . 'library/weight.php');
require_once(DIR_SYSTEM . 'library/length.php');

Replace with,

// vQmod
require_once('../vqmod/vqmod.php');
VQMod::bootup();

// VQMODDED Startup
require_once(VQMod::modCheck(DIR_SYSTEM . 'startup.php'));

// Application Classes
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/currency.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/user.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/weight.php'));
require_once(VQMod::modCheck(DIR_SYSTEM . 'library/length.php'));

Step-5: vQmod is now ready to use. Upload desired xml script to ‘vqmod/xml’ folder

Step-6: How this .xml file should look? For exampale we need to add a menu item “Homenet” under “Extension” menu in the admin panel. So we need to create a file named admin_menu_modification.xml in ‘vqmod/xml’ folder like;

‘vqmod/xml/admin_menu_modification.xml’

			<add><![CDATA[$this->data['text_homenet'] = $this->language->get('text_homenet');]]></add>
		</operation>
		<operation>
			<search position="after"><![CDATA[$this->data['feed'] = $this->url->link('extension/feed', 'token=' . $this->session->data['token'], 'SSL');]]></search>
			<add><![CDATA[$this->data['homenet'] = $this->url->link('homenet/homenet', 'token=' . $this->session->data['token'], 'SSL');]]></add>
		</operation>
	</file>
	<file name="admin/view/template/common/header.tpl">
		<operation>
			<search position="after"><![CDATA[<li><a href="<?php echo $feed; ?>"><?php echo $text_feed; ?></a></li>]]></search>
			<add><![CDATA[<li><a href="<?php echo $homenet; ?>"><?php echo $text_homenet; ?></a></li>]]></add>
		</operation>		
	</file>
	<file name="admin/language/english/common/header.php">
		<operation>
			<search position="after"><![CDATA[$_['text_feed']                        = 'Product Feeds';]]></search>
			<add><![CDATA[$_['text_homenet']                     = 'Homenet';]]></add>
		</operation>		
	</file>
</modification>

Wallah! You are done!

Step-7: Now log in to admin panel. Mouse over to “Extension” menu item, if everything works good then you can see a new menu item “Homenet” is added whithout changing any core system files.

Install vQmod in OpenCart using Autoinstaller:

Step-1: Download the latest version of vQMod and extract it.
Step-2: Use your FTP to upload the folder “vqmod” to your opencart store. Make sure vqmod/vqcache folders are writable (either 755 or 777).
Step-3: Now browse http://www.your-domain.com/vqmod/install
Step-4: If everything goes well, you should get a success message. If not then check permissions.

***Troubleshooting***
– Make sure you are giving the currect vqmod path like; require_once(‘../vqmod/vqmod.php’);
– Check if the vqmod folder and the vqmod/vqcache folders are writable (755)
– Verify that there are new “vq2” files in the “vqmod/vqcache” folder after loading your store homepage
– Some times you may need to create “mods.cache” file inside “vqmod” folder and make it writable (755)
– You may need to create logs” folder inside “vqmod” folder and make it writable (755)

Implementing Google federated login using Hybrid Protocol (OpenID+OAuth)

How it works ?

Just a few days ago, I was badly in need to implement Google federated login using Hybrid Protocol (OpenID+OAuth). After searching a while I found myself that I was not keen to read. So read the Federated Login for Google Account Users again and found the solution.
To use Google service all you need

OAuth Consumer Key
OAuth Consumer Secret

How to get OAuth Consumer Key and OAuth Consumer Secret

Step 1 : First you need to add your domain name in google. To add your domain click

Add a New Domain

Step 2 : In Add a New Domain put your domain (sign in if you don’t) and you will get Manage your.domain.name below.

Step 3 : Click on Manage your.domain.name will get Verify ownership page. You will have

Site URL
Verification status
Verification method

Verification Status obviously Not Verified . To verified your domain with Google service you can choose Meta Tag, Upload an HTML file or Add a DNS record from select box. Choose whatever you want. Here we take Meta Tag. Something like

<meta name="google-site-verification" content="OTInrbJb1bsZ4JODXahOcdA2Ab16zZEcOURtss2Fnws" />

Add this meta tag in your site root file (i.e: index.php or index.html) on your site and then click verify button.

Step 4 : After verification it’s time to get the OAuth Consumer Secret. Now create your certificate authority first. The easiest way to create X.509 certificates on Linux is the openssl command. In your LINUX box got to terminal and paste the following code.

$ sudo openssl req -x509 -nodes -days 365 -newkey rsa:1024 -sha1 -subj ‘/C=US/ST=CA/L=Mountain View/CN=www.example.com’ -keyout myr
sakey.pem -out /tmp/myrsacert.pem

Now, you have your .pem file in /tmp/myrsacert.pem and upload and save it to your google account management.
You will see something like:

OAuth Consumer Key: your.domain.name
OAuth Consumer Secret: mx4KGNaNdcqHt+BDuJusaUvc

Step 5 : You are all most done! Just download the Source Code and run. You will need Zend Gdata library. If you don’t have you can download it form here.

Source Code
Zend Frameword :: Zend Gdata

“The demo illustrates the simplicity of a combined user interface doing double duty: view a page requesting sign-on approval and access to your Google Docs and Spreadsheets services, click “Continue Sign-in”, and voila: you’re logged into the site and viewing a list of all your Google docs. All the authentication/authorization is happening behind the scenes, while the cost to the user is one page view and one click.”

Now you can play on Google as well. Visit Google Developer’s OauthPlayGround to discover OpenID+OAuth in action

[ubuntu] GrameenPhone’s Internet with Mobidata EDGE modem in ubuntu

Lot’s of UBUNTU users in Bangladesh are searching to configure Mobidata EDGE modem. Well, the most effective way to connect internet is wvdial. If it’s your lucky day then the following steps will work fine.

Step 1: First things first, make sure you are enable your repository from your software source.

Step 2: Now, in the terminal type

$ sudo wvdial

, If you are getting command not found that means you don’t have wvdialconf

For Ubuntu 9.10 (karmic koala) 4 files needed:

1. http://packages.ubuntu.com/karmic/i386/libwvstreams4.6-base/download
2. http://packages.ubuntu.com/karmic/i386/libwvstreams4.6-extras/download
3. http://packages.ubuntu.com/karmic/i386/libuniconf4.6/download
4. http://packages.ubuntu.com/karmic/i386/wvdial/download

All 4 files in .zip can be found (i386) into here

Update for Ubuntu 10.04
Although wvdial and dependencies are included into CD of 10.04 are NOT installed by default! Bug#400573
You do not need to download them, just use the .iso or LiveCD or LiveUSB following the procedure below:

1. right click ubuntu-10.04-desktop-i386.iso and ‘open with archive mounter’
(or mount LiveCD/LiveUSB)
2. right click on icon created (from 1) to ‘browse folder’
3. create a folder on Desktop (ex. named ‘wvdial’)
4. copy into that folder all 4 .deb files that exist into .iso/LiveCD/LiveUSB
… /pool/main/w/wvdial
and /pool/main/w/wvstreams
5. use System > Administration > Synaptic Package Manager
and then from menu File > Add downloaded packages > double click Desktop and then the folder you created at point #3, click open, follow instructions to
install

OR, you can got to step 5.

Step 3:If you can manage internet connection some how then go to terminal type

$ sudo apt-get install wvdialconf

Without installing PLEASE DON’T PROCEED.

Step 4: After installing wvdialconf you have a file name wvdial.conf in

/etc/wvdial.conf. Go to terminal type

$ sudo gedit /etc/wvdial.conf

. This will open the file with gEdit.

Step 5: Now copy and paste from below in /etc/wvdial.conf you are all most done!

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,”IP”,”gpinternet”
Modem Type = Analog Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyUSB0
Username = xyz
Password = xyz
Baud = 460800
New PPPD = yes

Step 5: You are done! Go to terminal and try again

$ sudo wvdial

. Hope you can find [connect] word!!

[NOTE:] make sure that your Mobidata EDGE modem found in /dev folder like /dev/ttyUSB0 or whatever! just put the name correctly in the modem section.

Now you can enjoy your GrameenPhone’s Internet with Mobidata EDGE modem in ubuntu all the time.
