I am writing this article based on my recent experience regarding how to write some complex queries using LINQ.

I’m not going to explain why we should use LINQ over lambda or neither Query Syntax vs. Method syntax in LINQ.

Let’s dig in..

LINQ Join column from 2 table:

Just for the demo, I have created Building & Resource classes. Resource having a relationship with Building via BuildingId column.

Now I have to write a query that returns ‘Distinct’ and ‘Active’ resources list i.e: Resource Id & Resource Name- Building Name. Ex: Physics Lab-Building 01. Here ‘Lab’ is the Resource Name and ‘Building 01’ is the Building name.

var resourcequery = (from resource in DbInstance.Resource
join building in DbInstance.Building on resource.BuildingId equals building.Id
where resource.IsActive == true
select new { resource, building } into t1
select new
{
Id = t1.resource.Id.ToString(),
Name = t1.resource.Name + "-" + t1.building.Name
}).Distinct().ToList();

Here is the final output:

Eid Mubarak!

Stay Home, Stay Safe.

تقبل الله منا و منكم

Last week one of my university juniors asked me this question! That, what’s the difference between Coding & Programming?

Then I thought I should write a post about it and try to explain. I believe it’s very important if you are working Software Industry you should know what you actually are!

Most people think both are the same thing! Not at all! There are differences between the two “worlds”. So let’s explore how professionals use them and try to understand the terms first by understanding what they mean.

What’s Coding?

Coding is how we communicate with computers. Code tells a computer what actions to take and writing code is like creating a set of instructions.
In order to become a coder, you need to be able to write code in different programming languages such as Java, C, PHP & so on. With this knowledge, you will be able to provide instructions and information to the computer to execute the programs you or your team creates.

Coding involves writing code for creating a software program or any sort of application, website, game.

What’s Programming?

There are many definitions of what programming is, but the one I prefer is: “Programming is how you get computers to solve problems.” There are two key phrases here which is important:

• you: without the programmer (you), the computer is useless. It does what you tell it to do.
• solve problems: computers are tools. They are complex tools, admittedly, but they are not mysterious or magical: they exist to make tasks easier.

In order to come up with a solution or an application, you will need to carry out a few steps:

• planning the application
• designing it
• testing the features
• deploying it
• maintaining it after development is finished

So it’s only fair to say that programming not only deals with coding but also implementing algorithms and much more.

Let me try to explain it in a simpler way so you can get a better understanding.

For example, you can program your watch to wake you up at 7 AM. Also, you can program the AC to come on at the temperature that you have chosen. These devices have code on the backend that works based on a set of instructions given by the user.

The Differences Between Coding and Programming in Brief:

1. Basic Difference:
   Coding is a part of programming that deals with writing code that a machine can translate. Programming is the process of creating a program that follows certain standards and performs a certain task.
2. Scope:
   Coding is about translating the requirement logic into machine-understandable code. In contrast, programming demands analysis and conceptualization of different aspects of any program and finding solutions to any issues that may occur during the process. It also involves critical parameters such as debugging, compiling, testing, and implementation.
3. Tools:
   Coding doesn’t require as many software tools since it’s just an act of code translation to machine-readable form. Just a simple text editor like notepad or WordPad is enough. As a coder, you just need to know the details of the syntax of any programming language.
   Programming requires that you perform document reviews and analysis along with coding that requires extra tools. These tools include code analyzing tools, databases, testing frameworks, compilers, assemblers, debuggers, and modeling algorithms. A programmer needs lots of experience to obtain these skills.
4. Expertise:
   Coders should have basic knowledge of programming.
   Programmers should have experience in creating algorithms, understanding requirements, processing data, modeling problems, and managing projects – these are just some of the practical skills needed.
5. Outcome:
   While coding, your expected outcome is part of or the whole project. The code acts as a set of instructions given to the computer.
   On the other hand, programming yields the whole application, software products, or a website that’s ready to use.

So, how both Coding and Programming works together?

Let’s explain this using an example to get a better understanding. Imagine we are creating an app to monitor something like our daily routine for us. How will these two different fields work together?

First the programmer will have to:

• plan the architechture of the app,
• list down features of the app
• designing the app

After the programmer is done with these first steps, they hand it over to the coder.
Now the coder will transform the ideas into code. After this process is done, the completed code is given back to the programmer.

Now the programmer will go through the code do some polishing by debugging, checking for errors, and doing tests before publishing the final product.
Now you can see how these two fields have come across together to work on an idea and produce something that’s usable.

Final Words:

Often people confuse programming & coding; hope by now you agree that they are distinctively different after comparing coding vs. programming with a number of factors.

Coding is the primary step and translates the requirements and codes to convert into a machine-readable syntax. Still, programming deals with the executable programs to produce the mechanical outputs following the inputs and requires the knowledge of the complete software development life cycle.

Are you looking for a straight way to add a new tab in my-account page in WooCommerce that can be implemented quickly and easily by any WooCommerce user irrespective of their level of skill?

Today, I’m going to show you how to add a custom tab on the WooCommerce My Account page – feel free to leave a comment below if you found this tutorial useful

To add a new tab in the WooCommerce my-account page, it entails four steps as follows:

1. Create a filter hook to add the new tab in my-account page and the filter should gather all the data that is displayed on the menu and then push in your new data.
2. Create a second filter that adds the URL redirect of the menu you added in the first step to the page you have created just now.
3. Adding the new endpoint under the Account menu
4. Add this code to your theme’s functions.php file or you can add this code to a plugin class or function and you will successfully add the new menu on my account page in WooCommerce.

1. Add the First Filter to Add Menu to My-Account Page

// Note: Resave Permalinks or it will give 404 error
function myaccount_add_notification_endpoint() {
    add_rewrite_endpoint( 'notification', EP_ROOT | EP_PAGES );
}
add_action( 'init', 'myaccount_add_notification_endpoint' );

This gonna create the new endpoint “notification” the new menu on my account page.

2. Add Second Filter to Add Menu to My-Account Page

function myaccount_add_notification_query_vars( $vars ) {
    $vars[] = 'notification';
    return $vars;
}
add_filter( 'query_vars', 'myaccount_add_notification_query_vars', 0 );

3. Insert the new endpoint into the My Account menu

function myaccount_add_notification_link_my_account( $items ) {
    $items['notification'] = 'Notification';
    return $items;
}
add_filter( 'woocommerce_account_menu_items', 'myaccount_add_notification_link_my_account' );

4. Add content to the new endpoint

function myaccount_add_notification_content() {
echo '<h3>Welcome to the new page</h3>;
echo do_shortcode( ' /* your-shortcode-here */ ' );
}
add_action( 'woocommerce_account_notification_endpoint', 'myaccount_add_notification_content' );
// Note: add_action must follow 'woocommerce_account_{your-endpoint-slug}_endpoint' format

Wrapping Up! You can find the whole code at the end of the post ?
Adding a new menu tab in my-account page on WooCommerce should not be a challenge anymore after reading this tutorial. I have tried to explain step-by-step and with a practical example on how to add a new tab in my-account page and add the content of your choice. I have also written other tutorials on how to show Store(Vendor) Name on Checkout page in WordPress and add a checkbox in checkout page for customer whether wants to be a member & send customer details to email.

So, this was the requirement from the client to show the Vendor Name on the Checkout page. Though the plugin shows the Vendor Name of each product on the right side just after the product name.
N.B: To support multi-vendor in WordPress I’m using Dokan Plugin.

Let’s copy the code from below:

add_action( 'woocommerce_before_checkout_form', 'print_vendor_name_on_checkout_page', 10 );
function print_vendor_name_on_checkout_page()
{
echo 'Shop: ';
foreach( WC()->cart->get_cart() as $cart_item_key => $cart_item ){
$authror_id = $cart_item['data']->post->post_author; // <=== The post author ID
$author = get_user_by( 'id', $authror_id );
$store_info = dokan_get_store_info( $author->ID );
$store_title= $store_info['store_name'];
}
if ( !empty( $store_title ) ) { ?>
<span class="details">
<?php echo $store_title; ?>
</span>
<?php }
} 

That’s all! We’re done!
N.B.: In my case customers are allowed to order from one shop/vendor at once. That’s why I’ve printed the shop name outside the foreach function.

So, what if in your case you allow ordering from multiple stores? Just print the store name inside the foreach!

add_action( 'woocommerce_before_checkout_form', 'print_vendor_name_on_checkout_page', 10 );
function print_vendor_name_on_checkout_page()
{
echo 'Shop: ';
foreach( WC()->cart->get_cart() as $cart_item_key => $cart_item ){
$authror_id = $cart_item['data']->post->post_author; // <=== The post author ID
$author = get_user_by( 'id', $authror_id );
$store_info = dokan_get_store_info( $author->ID );
$store_title= $store_info['store_name'];
if ( !empty( $store_title ) ) { ?>
<span class="details">
<?php echo $store_title; ?>
</span>
<?php }
}
}

Done! Pretty simple, isn’t it?

Have you ever checked how much extra data a single embedded YouTube video can add to your web pages.

It’s easy to embed a YouTube video but have you ever checked how much extra data a single YouTube video can add to your web pages. The browser has to download nearly 800 KB of data (see screenshot below) for rendering the YouTube video player alone! And these files are even downloaded before the visitor has clicked the play button.

Only the base.js itself adds 492KB data! In total 23 requests are made and downloads ~800 KB data even before the play button is clicked! Don’t believe? See it in action here.

This increases the overall loading time of your page thus affecting the page speed. The other drawback with the default YouTube embed code is that renders a video player of fixed dimensions and isn’t responsive. If people view your website on a mobile phone, the video player may not resize properly for the small screen.

Normal YouTube Embed Video:

The standard embed code for YouTube uses the IFRAME tag(Google+ technique) where the width and height of the video player are fixed(may be you can write some custom CSS to make responsive) thus making the player non-responsive.

So, I’ve been looking for a solution so that the weight of the page doesn’t goes up. Finally found a solution!

Step-1:

Step 2:

Copy-paste the below JS anywhere in your web page. The script finds all embedded videos on page and then replaces the DIV elements with the video thumbnails and a play button (see demo in action).

Step 3:

You can see my solution on action here

Now, the page only downloads ~60KB before playing the video. I’ve reduces the downloads by 7.5% and one-third request (previous request was 23!)
