Calculator Job Description

The principle of the calculator:

Calculator Options

Also, all calculators have the following individual settings:

General settings:

• The name of the button is the default Calculate. You can specify for example: Get the result
• Text before sum - default: Result. It is displayed before the result of the calculation.
• Text after sum - default: Rub. For example, you can specify $.
• Action forms - where to redirect the user after calculation. (Only works in cases of disabled JavaScript)
• To round the result - you can select the function with which the sum of the result will be processed. Available to you: Round (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 existing ones.

Mail settings:

• Enable sending of letters - if you want to send letters after calculation, select Yes
• Subject - Subject of the letter that is sent to E-Mail. After the topic is automatically added Username. For example: Calculation of the calculator from the user Vasya Pupkin.
• Which E-Mail to send - specify email. Default admin email.
• Text at the beginning of the letter - Text in front of the table with the results of the calculation
• Text in front of the form - Displayed in front of the form for sending a letter by the user
• Successful send message - Appears when a message has been sent successfully.

Field types, their parameters, description

Text block:

• Title - is displayed above the field.
• Text - you can specify any arbitrary text that does not participate in the calculation formula. The field supports html tags. Indents are added automatically (nl2br).
  All calculation results of the calculator are recorded in the session, in this connection, you can specify the following codes that will display the desired result from $ _SESSION.
  [session id = "number of calculator"] specify 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. Needed to work with field conditions.

Select:

• Title - is displayed above the field.
• Signs up - Arithmetic sign that will be in front of the field. For example + or + (
• Signs after - Arithmetic sign, which will cost after the field. For example - or) -
• List - This field allows you to create options in the drop-down list. In previous versions, lists were compiled according to the following pattern:
  [price]: field name;
  [price2]: field name2;
  Since version 3.5, the list template has become simpler:
  price: field name
  price2: field name2
• This field is involved in the calculation formula - If you want to exclude this field from the calculation formula, select the option No. The selected parameters by the user will be recorded in the session.
• Visually hide the field - adds display: none for the field block. Needed to work with field conditions.

Checkbox:

• Similar to the SELECT field except parameters:
• Action with data - Arithmetic sign, which means the action between the selected checkboxes.
• 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 is involved in the calculation formula - If you want to exclude this field from the calculation formula, select the option No. The selected parameters by the user will be recorded in the session. It is worth considering the moment, if the field does not participate in the formula, you do not need to specify the "Action with data" parameter, then you will be able to see all the data that the user selected in the email being sent.

Radio:

• Similar to the SELECT field.

Input Text:

• Signs up - Arithmetic sign that will be in front of the field. For example + or + (
• Signs after - Arithmetic sign, which will cost after the field. For example - or) -
• Default - You need to specify the number that will be used in the calculation in the case when the visitor did not enter anything in the field.
• Price - You need to specify the number that will be associated with the action specified in the field parameter and produced with the data entered by the user.
• Action with data - 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. Needed to work with field conditions.
• This field is involved in the calculation formula - If you want to exclude this field from the calculation formula, select the option No. The selected parameters by the user will be recorded in the session. It is worth considering the moment, if the field does not participate in the formula, you do not need to specify the “Action with data” parameter, then you will be able to see all the data that the user entered in the email being sent.

Input Hidden:

• Signs up - Arithmetic sign that will be in front of the field. For example + or + (
• Signs after - Arithmetic sign, which will cost after the field. For example - or) -
• Price - You need to specify the number that will be involved in the calculation.

$ _SESSION:

• Signs up - Arithmetic sign that will be in front of the field. For example + or + (
• Signs after - Arithmetic sign, which will cost after the field. For example - or) -
• 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 of the calculator from which to get data
• Field ID or sum - Specify the field ID or write sum to get the result.

jQuery field:

• Signs up - Arithmetic sign that will be in front of the field. For example + or + (
• Signs after - Arithmetic sign, which will cost after the field. For example - or) -
• 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 up - Arithmetic sign that will be in front of the field. For example + or + (
• Signs after - Arithmetic sign, which will cost after the field. For example - or) -
• What function we use - It is possible to choose two functions:
  1. Extract square root - allows you to extract the square root of a field or group of fields. To work correctly, be sure to wrap the field in parentheses. For example:
  We want to extract the square root of 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 of a group of fields, we should also wrap them in square brackets:
  [12] (15 + 57-11)
  2. Raise to Degree - allows you to raise to the power a field or a group of fields. For correct operation, the field must be covered by brackets! At the end of the bracket we indicate the degree to which the field is to be erected. For example, we will raise the field 10 to the power 2:
  [12] (10, 2) - where 2 is a degree.
  We must specify in the “Sign before” or “Sign after” of the field that we raise the following parameters :, 2)

Slider:

• Signs up - Arithmetic sign that will be in front of the field. For example + or + (
• Signs after - Arithmetic sign, which will cost after the field. For example - or) -
• Default - You need to specify a number that will display a slider in the specified interval between the Minimum and Maximum values.
• Visually hide the field - adds display: none for the field block. Needed to work with field conditions.
• Minimum value - You need to specify the number, which will be the minimum value of the slider.
• Maximum value - You need to specify the number, which will be the maximum value of the slider.
• Step - You need to specify the number with which step the slider will “slide”.
• Position - the position in which the slider will be displayed. Vertical or Horizontal.
• This field is involved in the calculation formula - If you want to exclude this field from the calculation formula, select the option No. The selected parameters by the user will be recorded in the session.

Condition IF VAL Field == Val User:

• Which field to compare - Enter the ID of the field, the value of which we will compare to fulfill the condition. Works for: Input Text, Select, Checkbox, Radio, Slider.
• What value should the field have ? Specify the value to be compared in the condition. For example 100
• Which fields are displayed - Specify the field IDs, separated by commas, to be displayed and included in the calculation formula. For the specified fields, the parameters “Visually hide this field” should be set: “Yes, add display: none”
• Which fields are hidden - Specify the field IDs, separated by commas, that need to be hidden and excluded in the calculation formula. The specified fields “Visually hide this field” must be set to: “No”
