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.

Hi, I was hoping this plugin would be the solution to a feature a website project needed and while it worked as intended, there was a little compatibility issue the plugin had with the theme I was using. On pointing this out to the developer, they immediately got on to it and resolved it within a few correspondences. There was never a hint of "not a plugin issue it's your theme", the support simple came back with, "Here is the solution". I hope them all the success with this plugin. Great Work.
