Display Names differ from Usernames in WordPress?


Do users register in your WordPress website and their profile display name is different than their registered Username? Well all you need to do is to add the below code in your functions.php file. This php code will force usernames to be the same as display names. Note that it is always recommended to write the code in the functions.php file located inside a child-theme because you will not lose any modifications you write there, even if you update your theme.


function wpse_filter_user_data( $data, $update, $id) {
  if( isset( $data[ 'user_login' ] ) ) {
    $data[ 'display_name' ] = $data[ 'user_login' ];
    return $data;
  $user = get_user_by( 'email', $data[ 'user_email' ] );
  $data[ 'display_name' ] = $user->user_login;
  return $data;
add_filter( 'wp_pre_insert_user_data', 'wpse_filter_user_data', 10, 3 );

Php price calculation using checkboxes

Hello, in this tutorial, i will show you how to calculate price in php webpage using html checkboxes.

Step 1: Create the html form

The first thing you need to do is to create the html document and make the form with the checkboxes.

<form action="index.php" method="get">
<input name="choice[]" type="checkbox" value="1" /> Chicken, Price: 8 Euros<br/>
<input name="choice[]" type="checkbox" value="2" /> Meat, Price: 10 Euros <br/>
<input name="choice[]" type="checkbox" value="3" /> Potatoes, Price: 2.50 Euros<br/>
<input name="choice[]" type="checkbox" value="4" /> Salad, Price: 5 Euros <br/>
<input type="submit" value="order" />

The above code gives the following output:

Chicken, Price: 8 Euros
Meat, Price: 10 Euros
Potatoes, Price: 2.50 Euros
Salad, Price: 5 Euros

Step 2: Create the php code

It is required to make a new index.php  file, since the form action is set to index.php. Index.php is the file we will write the below code.

        if(isset( $_GET["choice"] ))
        $food = $_GET["choice"];
        $c = count($food);
        $price = 0.0;
            if($food[$i] == 1){
                $price = $price + 8;
                echo "You have selected chicken<br>";
            if($food[$i] == 2){
                $price = $price + 10;
                echo "You have selected meat<br>";
            if($food[$i] == 3){
                $price = $price + 2.50;
                echo "You have selected potatoes<br>";
            if($food[$i] == 4){
                $price = $price + 5;
                echo "You have selected salad<br>";
        }//end for
        echo "<br>Final Price is:" .$price. "<br>";
        }//end isset
            echo 'Please choose something!';

A complete result of this tutorial is like below:

Chicken, Price: 8 Euros
Meat, Price: 10 Euros
Potatoes, Price: 2.50 Euros
Salad, Price: 5 Euros

i5 650 vs Xeon x3470 (Rx 460 2gb): Benchmark on 5 games

In this video i am comparing two first generation CPUs with some benchmarks and gaming. i5 650 (dual core) is compared with the Xeon x3470 (quad core).

My pc specs on Dell Inspiron 580:

CPU: Xeon x3470 2.9 Ghz

Gpu: Rx 460 2gb Memory: 6gb ddr3 @ 1333Mhz

Motherboard: 0C2KJT

Benchmarked games: Cs go , Farcry Primal, witcher 3, gta v, battlefield 1. Note that games are recorded with software, so fps drop especially on the i5. My current PC specs: http://www.userbenchmark.com/UserRun/…

Frequently asked questions:

-Is Xeon x3470 still a good CPU in 2018?

Yes, combined with a gtx 1050ti, would be still very powerful to play most games with decent fps.

– Can Xeon x3470 be overclocked?

Yes, if your motherboard supports it.

-Where can i find that cpu?

You can find that used on Aliexpress for less than 35 EU

-How can i see if my motherboard supports Xeon x3470?

See for user benchmarks on that cpu in the following link: https://goo.gl/J7BSVG

-Do i need to replace the stock cooler when upgrading to xeon?

if xeon’s TDP (95 watts) is greater than your old cpu TDP, then yes.
