Twig Set

Introduction

Twig Set is a powerful feature in the Twig templating engine that allows developers to create and assign variables within templates. It provides a clear and concise way to manage variable assignment and reuse values throughout the template.

Syntax

The syntax for using Twig Set is as follows:

{% set variable = value %}

• variable: The name of the variable to be assigned.
• value: The value to be assigned to the variable.

Usage

Twig Set can be used in a variety of scenarios, including:

1. Variable Assignment

You can use Twig Set to assign values to variables:

{% set name = 'John' %}
{% set age = 25 %}

2. Variable Reassignment

Twig Set allows you to reassign values to variables:

{% set name = 'Jane' %}
{% set age = 30 %}

3. Variable Calculation

Twig Set can be used to perform calculations and assign the result to a variable:

{% set total = 5 + 7 %}
{% set average = (10 + 20 + 30) / 3 %}

4. Variable Access

You can access the assigned variables later in the template:

<p>Name: {{ name }}</p>
<p>Age: {{ age }}</p>
<p>Total: {{ total }}</p>
<p>Average: {{ average }}</p>

5. Global Variables

Twig Set allows you to assign variables globally, making them accessible throughout the entire template:

{% set _global.page_title = 'My Website' %}

You can then use the variable {{ _global.page_title }} anywhere in the template.

Conclusion

Twig Set is a versatile feature in Twig that simplifies variable assignment and calculation. It helps to enhance the flexibility and readability of your Twig templates by allowing you to easily assign and reuse values throughout the template.
