Syntax for Concatenating Strings in Twig

The most straightforward way to concatenate strings in Twig is to use the ~ operator. This operator joins two or more strings together into a single string.

{% set myString = "Hello" ~ " " ~ "World" %}

In the example above, we concatenate three strings ("Hello", " ", and "World") into a single string myString. The result of myString will be "Hello World".

Another way to concatenate strings in Twig is to use the join filter. This filter joins an array of strings into a single string using a separator.

{% set myArray = ["Hello", "World"] %}
{% set myString = myArray|join(" ") %}

In the example above, we create an array of strings ("Hello" and "World") and join them together using a space as a separator. The result of myString will be "Hello World".

Examples of Concatenating Strings in Twig

Let's take a look at some examples of how to concatenate strings in Twig.

Example 1: Concatenating Strings with Variables

{% set firstName = "John" %}
{% set lastName = "Doe" %}
{% set fullName = firstName ~ " " ~ lastName %}

In the example above, we concatenate two variables (firstName and lastName) into a single variable fullName. The result of fullName will be "John Doe".

Example 2: Concatenating Strings with Arrays

{% set myArray = ["Hello", "World"] %}
{% set myString = myArray|join(" ") %}

In the example above, we create an array of strings ("Hello" and "World") and join them together using a space as a separator. The result of myString will be "Hello World".

Example 3: Concatenating Strings with Constants

{% set myString = "Hello" ~ " " ~ "World" %}

In the example above, we concatenate three constants ("Hello", " ", and "World") into a single string myString. The result of myString will be "Hello World".

Conclusion

Concatenating strings in Twig is a simple task that can be accomplished using the ~ operator or the join filter. Whether you are concatenating variables, arrays, or constants, Twig provides a flexible and powerful way to join strings together.
