Get the node title conditionally in a view rewrite field [closed]

Question

How can I get the field for the title of the content?

In twig I need to do this (for jssor slider) :

{% if field_titre_url_externe is not empty  %}
  {{ field_titre_url_externe }}
{% else %}
  {{ field_title }}
{% endif %}

but field_title is showing nothing, so what is the name of this?

EDIT :

I'm talking about the title of a node , article or content type

In my frontend, the title has the class views-field-title

See this image for more details (that's what I want to do):

Access the field_url_externe is not working actually... Accessing this field will solve my problem

Answer 1

This is the correct value for the rewrite field:

{% if field_url_externe is not empty  %}
  {{ field_url_externe }}
{% else %}
  {{ title }}
{% endif %}    

You can see the available fields in the "Replace Patterns" expandable link.

Answer 2

Is title a field you made or do you mean the node title? Node title can be printed with either {{ label }} or {{ node.getTitle() }}.

Fields that you created on the node, they are rendered out as:

{{ content.field_title }}

Which can be checked as:

{% if node.field_title_external is not empty  %}
  {{ content.field_title_external }}
{% else %}
  {{ node.getTitle() }}
{% endif %}

You can also use {{ label }} instead of {{ node.getTitle() }}.
