Set Variable Value
This action allows you to store a value inside a variable or a custom field. This is very useful when you want to collect data from your users.
The Different Types of Value
Once you click on the set custom field action, you’ll be able to choose which custom field needs some to update in terms of value.
You can either put in some data or even another custom field as a value as well.
Should you need to create a new custom field, just type in the name and choose the type of custom field you’d like to create.
Variable Operations
UChat provides you with various built-in operations for variable modification.
There are 6 types of variable in UChat:
Type | Storage | Example | Operation |
|---|---|---|---|
Text | letters, words, sentences... | Hi, UChat. | cutting, change case, encode, decode... |
Number | number | 123.45 | + - x ÷, mod, power, log, root, round... |
Boolean | either "yes" or "no" | yes | assign |
Date | date | 2021-03-30 | format, add months/weeks/days |
DateTime | date and time | 2021-03-30 16:52:00 | format, add months/weeks/days/hours/minutes |
JSON | a series of variables | {"name":"jack", "age":"10"} | load, get, update, remove, count, sum, average, sort, shuffle, reverse... |
Click "Basic Actions" in the Action step and here are the "Set Variable Value" and "Clear Variable Value".
Clear Custom Field / Clear JSON
To clear text, number, boolean, date, datetime variable, please use the Clear Custom Field action.
To clear JSON variable, please use the Remove All Items operation in the JSON Operation.
input value
"input value" operation is used to assign value to a variable. This operation works for any variable type.
TIP - "input value" for text variable can be used to connect several text variables. See the below picture for where to put original value and operated value.
Math Formula
With this operation, you can now do formula calculation directly in the Action Step - "Set Variable Value" and Condition Step - "Value".
Math operations and function supported:
+, -, *, e, pi, PI, abs(), min(), max(), ceil(), floor(), log(), pow(), round(), sqrt(), sin(), cos(), tan()
Please note that If the formula is invalid, the system will return 0 to number variable and empty to text variable.
