### Definitions

 * **Field** – is used to get user’s input on the woocommerce product page. Custom
   Field can be used to calculate the price (is used in formula)
 * **Fieldset** – store manager can create the fieldset (set of custom product fields)
   which consists of different **Fields**. Fieldset must have at least one **Field**
   and the expression (formula) to calculate the product price
 * **Expression/Formula** – mathematical and/or logical expression using to calculate
   the woocommerce custom price. The expression can be single-line, conditional 
   price addons (product addons). **Expression** is protected and calculated only
   server-side.
 * **Validation** – each **Field** has specific requirements to be met. Incorrect
   values make it impossible to calculate the woocommerce custom price and add the
   product to the cart.
 * **Global Parameters** – are numeric variables which can be used in formulas across
   all fieldsets.

### Formula/Expression Builder

Use field’s values as variables to calculate product price. Drag&drop conditional
statements.
 You can use product addons to add extra price to the product regular
price.

### Price Add-Ons

Use custom fields to make Product Addons.

### Display Fields

Assign fields to products, categories or product tags. Include/exclude options.

Mass assignment.

### Validation

Each field has built-in validation tests on user input. You can define additional
conditions.

### Protected Formula

The price is calculated server-side only, so the Client can’t see exact expression.

### Advanced Customization

Field HTML templates can be overloaded in your theme file. Each field has CSS class
to set custom styles.

### Functions

You can use basic math functions in the formula. Fields such as Multi-checkbox, 
Date Picker, Date Range Picker has additional functions to get sum, min, max value
or get date, days between dates values as number.

### Global Parameters

You can define numeric variable across all fieldsets. You can modify all prices 
by global parameters.

### Cart

The customer can edit product options after adding to cart.

### Integration with ACF

You can use `acf('field_name')` function to get ACF field value in custom price 
formula.

 [french2webdesign](https://profiles.wordpress.org/french2webdesign/) 08. travnja

This plugin looks promising in the beginning. However I see the author does not 
answer any support requests the last year. He also does not update the plugin. So
this means that this plugin is probably abandoned, and not futur-proof. If I get
a proof-of-support, I change my rating to 5 stars and I will support the author.
When I want to visit his website he mentioned for support, I get a Norton Anti-Virus
warning for dangerous page redirect…
