5. Custom Formula

Price can be set using custom formula, where admin can configure any mathematical operations that supported by Javascript and PHP , as well it supports ternary conditional operations.

While configuring the formula, it can use some predefined keywords in formula which will be quoted using { and }.  And also can refer other fields by using field element_ID.

Below are the list of predefined variables

{value}: Value entered by custom on the form.

{quantity}: Product quantity chosen by customer.

{product_price}: Product base price.

{unixDays}: To find the number of days.

{this.count}: To find the count of options that the user selected.

{value.length}: To find the length of the string entered in a field.

Referring other fields price and value

{field.element_id_of_the_field.price}: which used to refer price of other fields in a formula.

{field.element_id_of_the_field.value}: which using to refer value of other field in a formula.

 1. Set price based on the value percentage 

{value}*10/100

2. Set price if the value is greater than 2. Here we utilize javascript/php ternary operator

({value}>2)?{value}*10:0

Here it checks if the value entered is greater than 2, and if yes, it multiply value by 10, else it will set price as 0.

3. Set price based on quantity customer choose

(100/{quantity })*{value}

Here by increasing the quantity, the price can be reduced.

4. Set price based on other field value 

{field.wcpa-radio-group-1548937046157.value}*{value}

Here it refers to the value of another radio field and using it in a formula. It multiplies the value of the radio field with the value of user input for the text/number field.

wcpa-radio-group-3590011506 is the element id of radio field, You can check below screenshot where it marked how we can get an element ID.

5. Setting Multiple Conditions

You can add multiple conditions for the same option price using the ternary operator. For example,

Suppose you have a product and it has a varying options price per number of options varies. One example condition is given below.

• 1-100 -> {value}*100
• 101-200 -> {value}*80
• >200 ->{value}*60
