How to remove cents in Gravity Forms prices

Behavioural economics teaches us that people are more prone to purchase when prices are in a round amount with fewer numbers. For example, showing a price of $190 will result in more sales than displaying $190.00. All good and well but how do we do this when we use Gravity Forms with WordPress. The price field options allow for neither rounding nor displaying prices with zero decimal places (i.e. remove showing the cents in the price).

The answer lies in manipulating the Gravity Forms defaults for our chosen currency (in my case I use Australian dollars).

How to display whole dollar prices only

To display prices without the cents field on your Gravity Form fields merely add the following to your WordPress functions.php file:

add_filter( 'gform_currencies', 'update_currency' );
function update_currency( $currencies ) {
$currencies['AUD'] = array(
'name' => __( 'Australian Dollar', 'gravityforms' ),
'symbol_left' => '$',
'symbol_right' => '',
'symbol_padding' => ' ',
'thousand_separator' => ',',
'decimal_separator' => '.',
'decimals' => 0
);

return $currencies;
}

In the code above you’ll need to change the references to AUD and Australian Dollar to your currency needs. You’ll also need to amend the symbol_left value as appropriate. Below is a table of currency names and three letter abbreviations as included with Gravity Forms by default.
