Formatting a custom number field to add commas

Code Snippet Related Categories

Reason for needing the Code Snippet

I needed to format a number field (999,999,999), coming from a custom field number-format (no other characters permitted in the number entry field). No “$” no commas or decimal points, etc. to output as a normal currency format.

When displaying the number I could add a “$” in front of the number, but couldn’t find a way to format the number since you can’t do that with CSS.

What the Code Snippet does

This is a combo of a WordPress function added to the functions.php file that creates a shortcode that can then be used in a Beaver Builder Themer text or html module to output the raw number into a currency format.

For example you would enter 10000 into the custom field when editing the post, but when viewing the post the number now looks like $10,000.

What the page looks like Before and After

Here's the Code Snippet

  • Step 1: add this code to your functions.php file
    • function format_my_number($atts) {
      $num = $atts["value"];return number_format($num, 0, '.', ',');
      add_shortcode("custom-number-format", "format_my_number");
  • Step 2: now you  can use a shortcode in a text area to display a number that is entered in a custom number field, but with commas added when displayed:
    [custom-number-format value="PASS-YOUR-CUSTOM-FIELD-VALUE"]

    • this code is NOT dependent on Beaver Builder or, you could use any area that takes a shortcode and alternatively use ACF for example.
  • Step 3: In the case of Beaver Themer and using custom fields you wind up inserting a shortcode by using the Beaver Themer field connectors and passing the custom number field and inserting it inside the custom number format shortcode.
    • The custom field is inserted as a shortcode, in this example it's:

      -- So we wind up with Nested Shortcodes!

    • The complete nested shortcode looks like this:
      [custom-number-format value=""]

Limit search for phrases by using " " around the phrase
