Woocommerce rounding prices up - woocommerce

Question

I have set prices 7,09 and in cart it shows 7,00.
How I can remove this rounding? I have custom variation price field.
My code:
woocommerce_wp_text_input(
array(
'id' => '_number_field[' . $variation->ID . ']',
'label' => __( 'Aluse hind', 'woocommerce' ),
'desc_tip' => 'true',
'description' => __( 'Sisesta aluse hind.', 'woocommerce' ),
'value' => get_post_meta( $variation->ID, '_number_field', true ),
'custom_attributes' => array(
'step' => 'any',
'min' => '0'
)
)
);
add_filter('woocommerce_product_variation_get_price', 'custom_product_get_price', 10, 2 );
add_filter('woocommerce_show_variation_price', function() { return TRUE;});
function custom_product_get_price( $price, $product ){
if (!empty(get_post_meta( $product->get_id(), '_number_field', true))) {
return get_post_meta( $product->get_id(), '_number_field', true);
} else {
return get_post_meta( $product->get_id(), '_price', true);
}
}

As you can see here, looks like it will always be a small change in the zecimals

Answer 2

It is not a rounding problem. You're just passing a string as a price and the float conversion truncates the decimals.
If the value of the custom field _number_field uses a comma it must be converted to a numeric value (float), replacing the comma with the decimal point.
In your log file you will also find the notice: Notice: A non well formed numeric value encountered.
Furthermore, the woocommerce_product_variation_get_price hook already returns the meta _price of the product variation so the else declaration is not necessary.
You can optimize the custom_product_get_price function like this:
add_filter('woocommerce_product_variation_get_price', 'custom_product_get_price', 10, 2 );
function custom_product_get_price( $price, $product ) {
if ( ! empty( get_post_meta( $product->get_id(), '_number_field', true) ) ) {
$new_price = get_post_meta( $product->get_id(), '_number_field', true );
$new_price = (float) str_replace( ',', '.', $new_price );
}
if ( isset($new_price) ) {
return $new_price;
} else {
return $price;
}
}
The code has been tested and works.
