The Product price calculator tab on a product editing page and its features
After enabling the Product price calculator for a certain product, administrator should do all necessary actions in the Product price calculator tab on a product editing page.
1. Click the Product price calculator tab and you will see the following sections:
2. In the Fields section please specify:
Name - the name of a dimension parameter (for example, width).
Position - the position of the dimension parameter in the formula.
Default value - specify a default numeric value for a dimension parameter which will be shown in the storefront for a customer.
Abbreviation - the name for the unit of measurement (for example, cm, meter, inch, etc.).
Minimum – the minimum allowed numeric value which can be entered by a customer. If a customer enters a number that is less than the allowed minimum, he will see an error message and his number will be replaced with the allowed minimum.
Maximum - the maximum allowed numeric value which can be entered by a customer. If a customer enters a number that is bigger than the allowed maximum, he will see an error message and his number will be replaced with the allowed maximum.
Selectbox - Use this field if you would like to allow customers to choose necessary dimensions from a selectbox (customers won't be able to enter them manually). Note! First you need to fill out all fields in the Fields section and enter a Formula, press Save and the checkbox below the Selectbox will appear. Tick this checkbox to use the selectbox. Don't tick it, if you don't need to use it.
Step - Use this field if you choose the Selectbox. Type in the step for numeric values which will be chosen by a customer from a selectbox.
Additional - Use this field for inches or yards. Here type in the part which goes after /. In the storefront the selectbox for a fractional part will appear. For example, if you entered 2 in the Additional field in the admin back-end, fractional part will look like 0, 1/2. If you entered 4, the fractional part in the storefront will be 0, 1/4, 1/2 (namely 2/4), 3/4. Thus, the figure which goes before / starts from 0 till the Additional - 1 (step is always 1). The figure that goes after / is the Additional value.
Additional Abbreviation - the name for the additional unit of measurement (inch).
Click on the plus icon to add a new field.
3. Options section
If the product has options, you will see the Options section. Option section includes the option values how they should be used in a formula.
4. Formula section
Create a formula in the Formula section according to the examples provided below on this page.
5. Formula description
Here you can input the description of the formula. This formula description will be displayed in the storefront below a product title, explaining customers how the calculator works. If you leave this section empty, customers will see the “Calculate your price” line below a product title.
6. Apply formula to other product
Click the Add product link to choose the products where you would like to apply the created formula.
Please note! Only a formula without options will be applied correctly. If a formula has options and you applied this formula to other products, please check and change the options id values in the formula or remove them if they are not necessary. Also, if you apply a formula to a product that already has a formula, it will be rewritten.
Formula example for width and height dimensions in meters (initial price is per a square meter)
Formula explanation:
[val_1] is the value for the dimension Name with the Position 1;
[val_2] is the value for the dimension Name with the Position 2;
[price] is the price per unit specified by the administrator in the price field on a product editing page, General tab.
Note! The same formula is for centimetres with the initial price for a square cm and for inches with the initial price for a square inch.
Formula example for width and height dimensions in centimetres (initial price is per a square meter)
Formula explanation:
The basic formula [val_1]*[val_2]*[price] is divided into [10000] because the price on a product editing page is entered per a square meter but calculator uses values in centimetres.
Formula example for a product with width, height and thickness dimensions in centimetres (initial price is per a cubic centimetre)
Formula explanation:
[val_1] is the value for the dimension Name with the Position 1;
[val_2] is the value for the dimension Name with the Position 2;
[val_3] is the value for the dimension Name with the Position 3;
[price] is the price per unit specified by the administrator in the price field on product editing page, General tab.
Note! The same formula is for meters with the initial price for a cubic meter and for inches with the initial price for a cubic inch.
Formula example for a product with width, height and thickness dimensions in centimetres (initial price is per a cubic meter)
Formula explanation:
The basic formula [val_1]*[val_2]*[val_3]*[price] is divided into [1000000] because the price on a product editing page is entered per a cubic meter but calculator uses values in centimetres.
Formula example for a product with width and height dimensions in inches with a fractional part (initial price is per inch)
Formula explanation:
[val_1] is the value for the dimension Name with the Position 1;
[addval_1]/[4] - is the fractional part for the Position 1. The figure 4 is used after / because it is entered in the Additional field in the Fields section.
[val_2] is the value for the dimension Name with the Position 2;
[addval_2]/[4] - is the fractional part for the Position 2. The figure 4 is used after / because it is entered in the Additional field in the Fields section.
[price] is the price per unit specified by the administrator in the price field on product editing page, General tab.
Note! You can use such standard symbols in the formula as “+” “-” "*" "/".
How to create a formula that will work with options
Product price calculator works correctly with options. It allows to add options on base of entered dimensions.
For example, you sell a table board, it has such options as a Top material (Oak, Birch, etc) and a Color (While, Black, etc.). Top material price depends on a price per a square meter. Color price is a fixed price that will be added to the final product price.
Let's see the formula example for this situation (initial price is per a square meter):
Once you have created the options for a product in the admin back-end, option values how they should be used in a formula appear in the Options section as it is shown on the screenshot above.
Formula explanation:
[val_1] is the value for the dimension Name with Position 1;
[val_2] is the value for the dimension Name with Position 2;
[opt_15] is the id value of the created Table top material option. Remember, in our example, this option has price modifiers that depend on a price per a square meter.
[opt_16] is the id value of the created Color option. Remember, in our example, this option has price modifiers that are fixed and should be added to the final product price.
[price] is the price per a square meter.
The formula looks as follows:
[val_1]*[val_2]*([opt_15]+[price])+[opt_16]
It means that Table top material option price [opt_15] is added to price per a square meter [price] then it is multiplied by the table area [val_1]*[val_2] and the Color option price [opt_16] is added to the final price.
| Formula with complex conditions |
This feature allows you to use conditions for the formula.
You can add additional fields on a product details page in the Product price calculator tab such as
See the example screenshots below:
To create a new Subfield, click on the Add Subfields link in the Subfields section and fill out the appeared form:
To create a field with conditions, click the Add field with condition link in the Fields with conditions section and fill out the appeared form:
After the creation of the Subfields and the Fields with condition you can create a formula using new parameters. See the screenshot below:
Please note! If you have problems with creating a correct formula, we will help you to do it free of charge.
