Add this code to your functions.php or snippet plugin.
The script selects all HTML elements with the class .donate using document.querySelectorAll(‘.donate‘). These elements are expected to be buttons designated for making donations.
The script reads the value of the data-donate attribute from the clicked button to determine how much the user wants to donate. If the attribute isn’t present, it defaults to €20.
Change the email and name fields according to your needs.

// Iterate over each donate button

// Add click event listener to each donate button
button.addEventListener('click', function() {
// Get the donate amount from the button's data-donate attribute
