}

After adding the above code to the site theme’s “functions.php” file, you will see the “Buy now” button on the product pages.

Customize the “Buy now” button

Find the section below in the code and enter the desired color code to modify the “Buy now” button’s color.

// Change button color from here
$color = "#ff6a00"; 

To change the text of the “Buy now” button, find the following section of the code and replace “Buy now” with your desired wording.

// Change the text of the buy now button from here
$button_text   = __("Buy now", "woocommerce");

Add buy now to some categury

To display the “Buy Now” button on products from a specific category, Find the $condition variable and replace it with the conditional tag below.
In the code below, instead of ‘tshirts’, write the Slug of category you want.

// conditional tags
$condition = has_term( [ 'tshirts' ], 'product_cat' ) ;

From now on, the “buy now” button will only be displayed for T-shirts.
If you want more than one category, separate each category Slug with a comma.

// conditional tags
$condition = has_term( [ 'tshirts', 'hoodies', 'decor' ], 'product_cat' );

  1. Hi there,

    Thanks so much for this! I would like to know how I can make the “Buy now” button a little smaller? I tried changing the margin px value from 5 to 4. I didn’t notice any change in the size of the button though.

    Appreciate it!
    Albert

    • Hi Albert
      If you want to customize the size of the button, this code will do the trick:

      a.custom-checkout-btn {
      width: 80px;
      height: 20px;
      flex: unset;
      }

      • Thanks so much!
        I’ve actually just managed to add a max height to the code 🙂
        I followed the same way the other lines were added and after a few tries, managed to get it right.

        I appreciate your fast reply!

  3. Hai, please help me on this. This code works perfectly fine for me, but I am facing one issue with the external or affiliated products. I don’t want this Buy Now button on External Products as it return a message in the cart window saying “This product cannot be purchased” O how do I remove this button from external products?

    • Hey Dhanuan!
      Thanks a lot for your comment.
      I made some changes to the code, so now the Buy Now button will only show up for simple and variable products.
