Description of the calculator

The principle of the calculator:

Calculator Options

Also, all calculators have the following individual settings:

General settings:

• The name of the button is Calculate by default. You can specify for example: Get the result
• Text before sum - default: Result. It is displayed before the calculation result.
• Text after amount - default: Rub. For example, you can specify $.
• Action forms - where to redirect the user after calculation. (Only works if JavaScript is disabled)
• Round the result - you can select the function with which the result will be processed. Available to you: Round (from 0 to 4 decimal places), Ceil and Floor.
• Calculator design: You can choose one of four ready-made themes for every taste, or make changes to an existing one.

Email settings:

• Enable sending letters - if you want to send letters after calculation, select Yes
• Subject - The subject of the letter that is sent to E-Mail. After the topic, the username is automatically added. For example: Calculation of the calculator from the user Vasya Pupkin.
• To which E-Mail to send - specify email. The default email address is admin.
• Text at the beginning of the letter - Text in front of the table with the calculation results
• Text in front of the form - Displayed before the user’s email sending form.
• Successful sending message - Displayed when the message has been sent successfully.

Field types, their parameters, description

Text block:

• Title - displayed above the field.
• Text - you can specify any arbitrary text that is not involved in the calculation formula. The field supports html tags. Indentation is added automatically (nl2br).
  All the results of the calculator’s calculations are recorded in the session, in connection with this, you can specify the following codes that will output the desired result from $ _SESSION.
  [session id = "calculator number"] indicate the number of the calculator field or specify sum to display the result [/ session]
• Visually hide the field - adds display: none for the field block. It is necessary for working with the condition field.

Select:

• Title - displayed above the field.
• Signs before - The arithmetic sign that will stand in front of the field. For example + or + (
• Signs after - The arithmetic sign that will cost after the field. For example - or) -
• List - This field allows you to create options in the drop-down list. In previous versions, the lists were compiled according to the following template:
  [price]: field name;
  [price2]: field name2;
  since version 3.5 the list template has become easier:
  price: field name
  price2: field name2
• This field participates in the calculation formula - If you want to exclude this field from the calculation formula, select the None option. The selected parameters by the user will be recorded in the session.
• Visually hide the field - adds display: none for the field block. It is necessary for working with the condition field.

Checkbox:

• Same as the SELECT field except for the parameters:
• Action data - arithmetic sign, which means action between the selected checkboxes.
• By default - You need to specify the number that will be used in the calculation in the case when no checkbox has been selected.
• This field participates in the calculation formula - If you want to exclude this field from the calculation formula, select the None option. The selected parameters by the user will be recorded in the session. It’s worth taking into account the moment, if the field is not involved in the formula, you do not need to specify the “Data action” parameter, then you can see all the data that the user selected in the message to be sent.

Radio:

• Similar to the SELECT field.

Input Text:

• Signs before  - The arithmetic sign that will stand in front of the field. For example + or + (
• Signs after  - The arithmetic sign that will cost after the field. For example - or) -
• By default - You need to specify a number that will be used in the calculation in the case when the visitor has not entered anything in the field.
• Price - You need to specify a number that will be associated with the action specified in the field parameter and performed with the data entered by the user.
• Data action - Arithmetic sign, which means the action with the entered data by the visitor and the price of the field.
• Visually hide the field  - adds display: none for the field block. It is necessary for working with the condition field.
• This field is involved in the calculation formula - If this field should be excluded from the calculation formula, select No. The selected parameters by the user will be recorded in the session. It’s worth taking into account the moment, if the field is not involved in the formula, you do not need to specify the “Action with data” parameter, then you can see all the data that the user entered in the message being sent.

Input Hidden:

• Signs before  - The arithmetic sign that will stand in front of the field. For example + or + (
• Signs after  - The arithmetic sign that will cost after the field. For example - or) -
• Price  - You need to specify the number that will be involved in the calculation.

$ _SESSION:

• Signs before  - The arithmetic sign that will stand in front of the field. For example + or + (
• Signs after  - The arithmetic sign that will cost after the field. For example - or) -
• By default  - You need to specify the number that will be used in the calculation when the data from the session is empty.
• Calculator ID - Specify the ID calculator, from which to get the data
• Field ID or sum - Specify the field ID or write sum to get the result

jQuery field:

• Signs before  - The arithmetic sign that will stand in front of the field. For example + or + (
• Signs after  - The arithmetic sign that will cost after the field. For example - or) -
• By default  - You need to specify the number that will be used in the calculation in the case when these fields are empty.
• Field ID  - Specify the ID of the field from which you want to copy data. Works for: Input text, Select, Radio, Checkbox, Slider

Arithmetic function:

• Signs before  - The arithmetic sign that will stand in front of the field. For example + or + (
• Signs after  - The arithmetic sign that will cost after the field. For example - or) -
• What function we use  - It is possible to select two functions:
  1. Extract square root - allows you to extract the square root from a field or group of fields. For correct operation , be sure to wrap the field in brackets. For example:
  We want to extract the square root from field 15, so the formula should look like this:
  [12] (15) - square brackets only visually indicate that this field is an arithmetic function.
  If we want to extract the square root from a group of fields, they should also be wrapped with square brackets:
  [12] (15 + 57-11)
  2. Raise to a power - allows you to raise a field or group of fields to a power. For correct operation, the field must be enclosed in parentheses! At the end of the bracket, indicate the degree to which the field should be raised. For example, we raise field 10 to degree 2:
  [12] (10, 2) - where 2 is the degree.
  We must indicate in the “Sign before” or “Sign after” the field that we raise to the power the following parameters :, 2)

Slider:

• Signs before  - The arithmetic sign that will stand in front of the field. For example + or + (
• Signs after  - The arithmetic sign that will cost after the field. For example - or) -
• By default  - You need to specify a number that displays a slider in the specified interval between the Minimum and Maximum values.
• Visually hide the field  - adds display: none for the field block. It is necessary for working with the condition field.
• Minimum value - You need to specify a number, which will be the minimum value of the slider.
• Maximum value  - You need to specify a number that will be the maximum value of the slider.
• Step - You need to specify the number with which step the slider will “slide”.
• Position - in what position the slider will be displayed. Vertically or horizontally.
• This field participates in the calculation formula - If you want to exclude this field from the calculation formula, select the None option. The selected parameters by the user will be recorded in the session.

IF VAL Field == Val User Condition:

• Какое поле сравниваем - Укажите ID поля, значение которого мы будем сравнивать для выполнения условия. Работает для: Input Text, Select, Checkbox, Radio, Slider.
• Какое значение должно быть у поля - Укажите значение, которое будет сравниваться в условии. Например 100
• Какие поля отображаем - Укажите ID полей через запятую, которые нужно отобразить и включить в формулу расчете. У указанных полей параметры «Визуально скрыть это поле» должен быть выставлен: «Да, добавить display: none»
• Какие поля скрываем - Укажите ID полей через запятую, которые нужно скрыть и исключить в формуле расчете. У указанных полей параметры «Визуально скрыть это поле» должен быть выставлен: «Нет»
