Fix for Codeigniter WHERE IN query issue due to comma

In the below code we have an array of ids named $list_ids. We would like to mark the status of rows with ‘my_id’ = 1, my_id = 2 and my_id = 3 as Completed.

            $data['status'] = "Completed";
            $list_ids = array(1,2,3);
            $this->db->where_in('my_id', $list_ids);
            $this->db->update('my_table', $data);
            echo $this->db->last_query();

But after executing the above query, you might be surprised. Only row with ‘my_id’ = 1 gets updated. You might notice no change to the other two rows? Why?

Look at the generated query below.

UPDATE `my_table` SET `status` = ‘Completed’ WHERE `my_id` IN(‘1,2,3’)

There is a comma before 1 and after 3. The query should be
UPDATE `my_table` SET `status` = ‘Completed’ WHERE `my_id` IN(1,2,3)
to work it as expected.

For that we need to pass an extra parameter to the where_in function. The working code is given below.

            $data['status'] = "Completed";
            $list_ids = array(1,2,3);
                   $list_ids, FALSE);
            $this->db->update('my_table', $data);
            echo $this->db->last_query();

You can see that, we changed the where_in code from
$this->db->where_in(‘my_id’, $list_ids) to
$this->db->where_in(‘my_id’, $list_ids, FALSE);

Hope it’s helpful.

Prevent bootstrap affix overlapping with footer

Fixing a div to the right side of your web page using
bootstrap’s affix method is easy.

Steps required are
1)Add data-spy=”affix” to the div you would like to fix in the right side. Also Add a class to the div, in the example i added the class as my-affix-div.
The whole affix div code is given below.

<div class="col-sm-5 pull-right my-affix-div" 
        data-spy="affix"  >
        <div class = "panel 
                panel-transparent affix_div" >
            <div class ="panel-heading">
                <h3 class = "panel-title">Summary</h3>

            <div class = "panel-body">
                <div class="row">
                    <div class="col-sm-4">

                    <div class="col-sm-3">

                    <div class="col-sm-3">

            <div class = "panel-footer">
                <form role="form" action="#"
                    <button type="submit" 
                          class="btn btn-default"


2)Then add the below Javascript code.

   {offset:{top: 75, bottom: 240}}

In the code we specified when the div should be fixed.
If the scroll top is more than 75 pixel, then the div with the class name my-affix-div will be fixed. If we scroll to the bottom and if the distance from bottom to the div is less than 240,
the div’s position becomes absolute.

At any moment the div with data-spy=”affix” , will be in one of the three states.
1)affix-top: If your scroll top is less than 75px.
2)affix: (If your scroll top is more than 75 px
and scroll bottom is more than 240 ).
3)affix-bottom: if your scroll bottom is less than 240.
We can specify styles of those states. Below CSS code is added to specify that the position should be absolute in both
affix-bottom and affix-top states. in affix state, the div will be fixed to the right side and distance to the top of the div will be

    position: absolute;
    right: 0;  
    position: absolute;
    right: 0;  
.affix {
        top: 200px;
        right: 0;

How to add popover to awesome font?

If you like to display a popover as shown in the above image,
You should include following files in your html head.

        <script src="js/jquery.min.js"></script>
        <script src="js/bootstrap.min.js"></script>
        <link rel="stylesheet" href="css/font-awesome.min.css">
        <link rel="stylesheet" href="css/bootstrap.min.css">


Below is the html body content. The popover should come when placing mouse over the awesome font with class name “fa fa-question”. The awesome font is written as an inner html of a tag. Two important attributes we added to the tag are 1)data-toggle=”popover” and 2)data-content=”[popover message]”.

<div class="container">
    <h2>Sample Popover Code</h2>
    <div class="panel-group">
        <div class="panel panel-default">
            <div class="panel-heading">Popover with awesome font</div>
            <div class="panel-body">
                <div class="row form-group">

                    <div class="col-sm-6">
                        <input class="form-control" type="text"
                               placeholder="Name"  name="name" />


                <div class="row form-group text-center">

                    <div class="col-sm-6">
                        <div class="input-group">
                            <input placeholder="Address"
                                   class="form-control pooja-star"
                                   type="text" name="address"/>
                            <span class="input-group-addon">
                                    data-content="Enter Address as
                                    <i class="fa fa-question"></i>

                <div class="row form-group text-center">
                    <div class="col-sm-6">
                <button type="submit" class="btn btn-primary">
                Save changes


Below javascript code is required, where we set when the popover should be displayed, and also we are defining the selector.

As we set selector: ‘[data-toggle=”popover”]’ and
trigger: ‘hover’, when we place mouse over an element with attribute data-toggle=”popover” the popover function will be called.

<script type="text/javascript">
    var popOverSettings = {
        trigger: 'hover',
        container: 'body',
        html: true,
        selector: '[data-toggle="popover"]', 

You can customize the look of awesome font and the background box
by adding your style to the below classes.

.input-group-addon {
    background-color: #your-color-here;

.fa-question {
    //style here

WHMCS 6 Database Queries

WHMCS6 use Laravel framework’s database component.
So Insert, Select, Update and Delete queries should be written in
Laravel style.

To perform the query, we should include the below code to the php file. You should replace the string path_to_init_folder with actual path to the init.php file within the WHMCS folder.

require "path_to_init_folder/init.php";
use Illuminate\Database\Capsule\Manager as Capsule;

Now let’s see how we can add a row to a table named my_sample_table.
We have two fields to insert. one is key and other one is value.

#Insert a row

$insert_array = array(
      "name" => $_REQUEST['name'],
      "relid" => $_REQUEST['productid']


  If you would like to get unique id of
  last inserted row

$insert_array = array(
   "name" => $_REQUEST['name'],
   "relid" => $_REQUEST['productid']
$row_id = Capsule::table('my_sample_table')

To update a table field, we can write the query as given below.

#Update a row
   ->where('id', '=', $invoice_id)
   ->update(array('status' => 'Paid'));
#Select multiple rows
$data = Capsule::table('tbldomains')
   ->where('domain', '=', '')
#Select a row
$data = Capsule::table('tbldomains')
   ->where('domain', '=', '')
#delete  row
    ->where('id', '=', 22)

Sample Join Query

If we have to join two tables discount_system and tblproductgroups on a condition = discount_system.pg_id, then we can write the join query as written below. For any select query we can just select intrested field’s values. In the below query we are just selecting three field values, they are, discount_system.discount_type and

    $discount_details = Capsule::table('discount_system')
                  '=', 'discount_system.pg_id'

To know more about the query,

CRUD Using Codeigniter

Db operations using codeigniter is explained briefly with codes.

Add a new row
A row can be inserted as shown below. To get the unique id of the row inserted, we have to use the function: $this->db->insert_id().

$data['user_gid'] = $user_gid;
$data['username'] = $user_name;
$data['email'] = $email;
$this->db->insert("mytable", $data);
$user_id = $this->db->insert_id();

Update a row
To update a row, we have to pass a where condition.
mutiple where conditions are possible. Below sample code just used one where condition.

$data['user_gid'] = $user_gid;
$data['username'] = $user_name;
$data['email'] = $email;
$this->db->where('user_id', $user_id);
$this->db->update('mytable', $data);

Select a row
To select a row that matches a where condition, we have to pass a
where condition just like we passed for update.
$this->db->select(“*”) will select all fields of the table.
To select just one field or specific fields we can specify the field names.

//get all fields
//to get  email and username
$this->db->where('user_id', $user_id);
$query = $this->db->get();
$row = $query->row_array();
return $row;

Select all rows

$query = $this->db->get();
$rows = $query->result();
return $rows;

Delete a row

$where = array(
    'user_id' => $user_id
$this->db->delete("mytable", $where);

Simplify Commerce Basics Using PHP SDK

Simplify Commerce is a payment gateway brought to you by MasterCard.
They have SDK for most of the programming languages. Here i am going to explain about PHP SDK of the Simplify Commerce. Using Simplify Commerce we can do payments using token. With this approach we don’t have to pass card number and also we are not storing the cc number in the database.

First of all you have to download the SDK and include it in your code as shown below. Link to download the SDK is

require_once 'Simplify.php'

In your Simplify account, you will have public key and private key for both live and sandbox. For testing use sandbox keys and when you go live have to use the live keys.

        require_once 'Simplify.php'
                $pub_key = $sandbox_pubkey;
                $prive_key $sandbox_privkey;
        } else {
                $pub_key = $live_pubkey;
                $prive_key = $live_privkey;
                Simplify::$publicKey = $pub_key;
                Simplify::$privateKey = $prive_key;
        }catch (Simplify_ApiException $e) {

How to get Simplify token?

You can create a token that can be used only once using the below code. You won’t be able to use the token more than once.

  $card = array(
      'addressState' => $state,
      'expMonth' => $exp_m,
      'expYear' => $exp_y,
      'addressCity' => $city,
      'cvc' => $cvc,
      'number' => $card_num
  try {
        $cardToken =  Simplify_CardToken::createCardToken(
              'card' => $card 
        $token = $cardToken->id;
  } catch (Simplify_ApiException $e) {
        die( $e->getMessage());

How to create a customer using the simplify token?
You can create a customer using the below code. You can see that we are using the token created. The below API will return a customer id
and we can use that for multiple transactions. Even though the token id can be used only once, the customer id can be used many times.

try {
    $data = array(
        'token' => $token,
        'email' => $email,
        'name' =>  $name,
        'reference' => $reference
    $customer = Simplify_Customer::createCustomer(
    $customer_id = $customer->id;
}catch (Simplify_ApiException $e){
    die( $e->getMessage());

How to make a payment using the simplify customer id?
The sample payment code is below. One important point to remember is, if you want to make a payment of $10, then we have to pass amount as
10 * 100, not 10. So for $10, we have pass amount as 1000 and currency as USD. We have to pass the $customer_id we generated in the previous step. We can pass anything as reference. Normally we pass order id or invoice id as reference.

$payment_data = array(
    'amount' =>  $amount * 100,
    'customer' => $customer_id,
    'description' => $description,
    'currency' => 'USD',
    'reference' => $invoice_id
try {
   $payment = Simplify_Payment::createPayment(
} catch (Simplify_ApiException $e) {
   die( $e->getMessage());

How to add a monthly subscription for the simplify customer id?
You can add a recurring payment from a customer as below.
amount and customer id, we already discussed in the above step.
If the customer will pay monthly, we have to set frequency as MONTHLY and frequencyPeriod as 1. If the customer will pay bimonthly then frequency should be MONTHLY and frequencyPeriod should be 2.
For semiannual payments set frequency=MONTHLY, frequencyPeriod=6.

Possible values for frequency are DAILY, WEEKLY, MONTHLY and YEARLY.

$subscription_data = array(
   'amount' =>  $amount * 100,
   'customer' => $customer_id,
   'frequency' => $frequency,
   'name' => $name,
   'frequencyPeriod' => $frequencyPeriod
try {
   $subscription  = Simplify_Subscription::createSubscription(
} catch (Simplify_ApiException $e) {
   die( $e->getMessage());

How can i submit a form using button class?

Assume that the form is as shown below.
Id of the form is block_form, and also we added a class named
block to the button.

<form id="block_form" method="post">		
	<input type="hidden" name="server_ip" value="y.y.y.y">
	<button class="btn btn-danger block" type="submit">Block</button>

Using Jquery we can submit the form by binding the class name to the click event. You can see the code for the form submition below.

$( ".block" ).click(function(event) {
	$.post( "ajax.php", 
		'action=block&'+ $('#block_form').serialize(),
		function( data ) {

Is Single Page Checkout Possible With WHMCS?

In WHMCS, when you try to order for a product.Assume that you are a logged in customer.How many steps are there now?

1)First you have to go to products display page.
Url will be http://[]/cart.php

2)If you click on “Order Now” Button of a Hosting product, You will be taken to a product configuration page. Url will be: http://[]/cart.php?a=confproduct&i=[x]

3)Then on clicking “Continue” You will be taken to a Review & Checkout Page.

4)On clicking Checkout Button, you will be taken to payment method selection page.

5)After selecting payment, you can click on the ‘Complete Order’ Button. That will place an order.

So total 5 steps are there.

Is it possible to do it in a single step? In other words, is one page checkout possible in WHMCS? Yes, it is possible. We have to use a hook for the purpose. In addition to that we have to make some changes for the template.

The hook should have some ajax post code. Sample code is below. The code will add the product to the cart before submitting the order form.

     $.post('cart.php', 'ajax=1&amp;a=confproduct&amp;' +
         function(data) {
           if (!data) {

We have a ready made single page checkout order form, with one time cost of $45.
please Contact Us by filling the form. We will get back to you asap.

Why no transaction data for a WHMCS order? Why the refund failing?

Even though order is complete, from Billing => Transactions List you might not see any transaction data related to the order.

If you go to admin/configgeneral.php, there is an option Auto Redirect on Checkout. Is the option ‘Automatically forward the user to the payment gateway’ selected? Then during the order, customer must have gone through the payment gateway module code. Even then why no transaction id and other data?

Go to ‘Manage Orders’ from admin side. Is the payment status of the order is complete? Is your refund failing for the invoice of the order? Are you getting the error ‘The refund attempt has failed. Please check the Gateway Log for more information’ when you try to refund?

It’s happening because the customer have some credit balance. The amount is deducted from that for the order.

If you are a developer and would like to test a refund for the payment gateway,you can simply reset the credit balance as zero for the customer.

Then place a new order and refund for that order will work.
To know credit balance of a customer with id [x],
go to the page clientssummary.php?userid=[x]
and search for Credit Balance.
