Calculated Fields Form WordPress 插件-WP-admin.cn

描述

The “Calculated Fields Form” plugin allows you to create web forms with calculated fields, whose values are dynamically calculated based on other fields’ values in the web form.

The possibilities are unlimited. For example, you can create forms with financial calculations, date operations to create reservation forms, and calculate the product prices. The plugin includes text operations for editing, translation, or advertising services. There are more advanced operations available such as determining the distance between addresses or generating graphs. The resulting forms are 100% mobile responsive.

The most impressive thing is that you don’t need to hire a programmer to create the forms. With basic knowledge, you will have a professional form in just five minutes.

Creating a form is all visual. The “Calculated Fields Form” plugin includes a form editor with multiple controls. Such as text fields, numeric fields, currency fields, slider controls, email fields, radio buttons, checkboxes, container fields, page breaks to create multipage forms, and most importantly, calculated fields.

The form editor includes a list of controls, a property bar to easily edit field properties, a dashboard where you can design your forms, and the attributes for form configuration. Also, the plugin comes with multiple predefined layouts to change the forms’ appearance. If there are not enough predefined layouts for your project, there is a style editor to customize the form’s design.

The “Calculated Fields Form” plugin includes integration with popular page builders:

Classic WordPress Editor
Gutenberg Editor
Elementor
Page Builder by SiteOrigin
Beaver Builder
WPBakery Page Builder
DIVI Builder

For other editors, it is possible to insert the form into the pages via its shortcode. Each web form has an associated shortcode that allows you to insert it wherever you want.

Please keep the plugin updated. Updates contain bug fixes as well as new features. The WordPress directory distributes the updates for the free version of the plugin. But for commercial versions, it would be necessary to register your copy of the plugin. The following link describes the registration process: CLICK HEREThis section mainly contains notes on features of the form builder that are too detailed to include in the main description.

Conditional rules

It is possible to show or hide form fields (dependent fields) based on the options selected in checkbox fields, radio buttons, the options selected in dropdown menus, or the result of calculated fields.

The value of a dependent field is zero when it is hidden/disabled. The plugin excludes the disabled form fields from the submission.

Additional details about the use of dependencies

Predefined values

The predefined values in the fields have two possible uses:

1- To fill the field by default. This makes it easier for the end-user to enter values.

2- Hint of the values to be entered in the field (like “Enter your name”). To use the predefined value as a placeholder, you must tick the “Hide predefined value on click” checkbox. The value will disappear once the user starts filling in the field. The calculated fields’ equations ignore placeholders.

The “User Instructions” attribute

The “User instructions” attribute in the field settings allows you to instruct the user on how to fill in the field. By default, the instructions appear as smaller text on the public website. But they can be configured as tooltips.

Adding CSS layout keywords

The “Add CSS layout keywords” attribute in the fields settings allows you to apply CSS styles to fields. You must only enter the name of the CSS class names, and not their definitions.

You can define the CSS classes via the “Customize Form Design” attribute in the “Form Settings” tab. This attribute contains a CSS editor with syntax highlighting and error checking.

If you want to assign several class names to the field, separate them by space characters.

The plugin includes multiple predefined classes that you can assign to the form fields.

More information about the form’s design can be found by reading the following post in the plugin’s blog:

Customizing the form’s design

The classes listed below allow you to align two, three, or four fields on the same line:

column2column3column4

For example, if you want to put two fields on the same line, give both fields the class name “column2”.

There are other variants for displaying several fields on the same line, such as container fields (Div or Fieldset). Container fields allow you to select the number of columns in your configuration. The following post describes all the alternatives for positioning the fields in the form:

Formatting the form (distributing the fields in columns)

Multi-page form

To create multi-page forms, you must insert “Page break” controls between fields belonging to different pages.

When the user presses the “Next Page” button, the plugin validates the fields in the current form. If there is any validation error (such as an unfilled required field), the plugin stops the “Next page” action.

Hidden calculated fields

Calculated fields include a checkbox in the configuration that allows them to be hidden from the public website. This feature is essential in those fields that are used to calculate intermediate values or when we want to show the results only in emails or thank you pages.

Equation / Formula format for calculated fields

Below, some possible formulas are included as examples, but the possibilities are endless.

With simple mathematical operations:

fieldname1 + fieldname2fieldname1 * fieldname2fieldname1 / fieldname2fieldname1 - fieldname2fieldname1 - fieldname2

With mathematical operations involving multiple fields and grouped fields:
```
fieldname1 * (fieldname2 + fieldname3)
```
With rounding operations. Round the result to two decimal places:
```
PREC(fieldname2 / fieldname3, 2)
```
There are infinite number of formulas that can be created using complex structures. For example, the following formula includes conditional statements:
```
(function () {if (100 < fieldname3) return fieldname1 + fieldname2;if (fieldname3 <= 100) return fieldname1 * fieldname2;})();
```
For complex formulas/equations you must use the function format with return statement to return the result to the calculated field:
```
 (function () {    var result = 0;    /* Your code here */    return result;}) ();
```

Operations and operators to use in equations/formulas

One of the “Calculated Fields Form” strengths is the ability to use any valid JavaScript code to implement the equations/formulas.

However, the plugin includes a wide variety of operations and operators to simplify the development process.

Mathematical Operations and Operators

Conditional Operations

Field Handling Operations

Operations for interacting with external services

Operations for handling URLs and query strings

In addition to the operation modules listed above, the Developer and Platinum versions of the plugin include additional modules:

Date Time Operations

Financial Operations

Distance and Travel Time Operations

Operations to generate charts

Controls available in the form generator of the “Calculated Fields Form”

The complete list of controls is available from this link: CLICK HERE

Create JavaScript variables from parameters received by “GET” or “POST”, “SESSION” variables, or “COOKIES” to use in the equations

The plugin includes the shortcode [CP_CALCULATED_FIELDS_VAR] to generate JavaScript variables from parameters received by “GET” or “POST”, “SESSION” variables, or “COOKIES”:

[CP_CALCULATED_FIELDS_VAR name="..."]

In the shortcode, you must replace the “…” symbols with the name of the parameter or variable. It will be the same name for the JavaScript variable.

For example:

[CP_CALCULATED_FIELDS_VAR name="varname"]

You can use the variables generated through the shortcode [CP_CALCULATED_FIELDS_VAR] in the formulas of the calculated fields: fieldname1*varname

The complete list of parameters accepted by the variables shortcode is available at the following link: CLICK HERE

Tips for calculating prices

One of the most frequent uses of our plugin is for price calculation. When displaying the price of a product, you may want to split the form into two pages. The first page would request the information needed to calculate the price, and the second page would include the calculated field with the final price. Also, you could use the “Instruct. Text” fields to indicate the terms, conditions, and validity period of the offer.

Note that you can make the “Instruct. Text” fields dependent on the calculated value. This allows you to vary the text displayed to the user depending on the calculated price, as the terms, conditions, or offers often depend on the transaction amount.

ClassicPress

This plugin is compatible with ClassicPress.

Add-ons

The add-ons are only distributed with the Developer and Platinum versions of the plugin.

The plugin lists the add ons in the “Add-ons area” of the settings page. To enable the add-ons, you must tick their corresponding checkbox and press the “Activate/Deactivate Add-ons” button.

Server-Side Equations add-on – included in the Developer and Platinum versions of the plugin

Define equations with PHP code on the server-side. The calculated fields call the server-side equations via AJAX.
