Eliminate a payment gateway on cart conditions

Eliminates a payment gateway when cart contains an item with a fractional quantity. Useful for gateways that can’t handle fractional quantities like PayPal.

add_filter( 'woocommerce_available_payment_gateways', function( $available_gateways ) {

	// Skip Admin Area
	if( is_admin() ) {
		return $available_gateways;

	// Loop Cart Items
	foreach( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {

		// Detect Fractional Quantity
		if( strpos( $cart_item['quantity'], '.' ) ) {

			// Found One, Remove PayPal And Stop Checking
			unset( $available_gateways['paypal'] );



	// Default
	return $available_gateways;

} );
