We generate some of the variables in flow process, those can used to pass the information your system.
Varibles consist of alphanumeric characters and underscores, should always start with a letter, and do not have any kind of leading sigil (that is, they look like var_name, not $var_name). Also variables should not consist of backslash(’') as our application treats the backslash as an escape character by default.
All variables should be enclosed between a set of double curly braces {{}} braces. ex: @{{to}}
You can access the Array of the variables with . dot notation.
| Name | Scope | Description |
|---|---|---|
| id | global | Sms unique id |
| text | global | Sms send by the customer |
| from | global | Sms from number with country code |
| to | global | Sms to number with country code |
| date | global | Current time in YYYY-MM-DD h:i:s format |
Output markup can take filters, which modify the result of the output statement. You can invoke filters by following the output statement’s main expression with:
Filters can also be chained together by adding additional filter statements (starting with another pipe character). The output of the previous filter will be the input for the next one.
{{mobile|slice:-10 }}
{{date|date_format:'d/m/y'}}
| Name | Description |
|---|---|
| append | append a string e.g. {{ 'foo' | append:'bar' }} #=> 'foobar' |
| ceil | rounds a number up to the nearest integer, e.g. {{ 4.6 | ceil }} #=> 5 |
| date_format | reformat a date {{start_at | date_format:'d/m/Y'}} |
| default | returns the given variable unless it is null or the empty string, when it will return the given value, e.g {{ undefined_variable | default: "Default value" }} #=> "Default value" |
| divided_by | integer division e.g. {{ 10 | divided_by:3 }} #=> 3 |
| downcase | convert an input string to lowercase |
| escape | html escape a string |

| floor | rounds a number down to the nearest integer, e.g. {{ 4.6 | floor }} #=> 4 |
| lstrip | strips all whitespace from the beginning of a string |
| minus | subtraction e.g. {{ 4 | minus:2 }} #=> 2 |
| modulo | remainder, e.g. {{ 3 | modulo:2 }} #=> 1 |

Strings. Literal strings must be surrounded by double quotes or single quotes (“my string” or ‘my string’). There is no difference; neither style allows variable interpolation.
Integers. Integers must not be quoted.
Booleans and nil. The literal values true, false, and nil.
Sometimes you want to use the other variable value with in variable to get the right value
[] can used to pass the variable with in other variable. ex: {{questions.[jump].name}}
Here we are using jump variable to get the original value of question.
it will be question.0.name, question.1.name, question.2.name
