Twig 的 tags学习（中文） 之一(4)

{% macro wrapped_input(name, value, type, size) %}
    <div class="field">
        {{ _self.input(name, value, type, size) }}
    </div>
{% endmacro %}
如果两个macro在不同的文件里，你需要使用import

{# forms.html #} 
 
{% macro input(name, value, type, size) %} 
  <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" /> 
{% endmacro %} 
 
{# shortcuts.html #} 
 
{% macro wrapped_input(name, value, type, size) %} 
    {% import "forms.html" as forms %} 
    <div class="field"> 
        {{ forms.input(name, value, type, size) }} 
    </div> 
{% endmacro %} 
{# forms.html #}

{% macro input(name, value, type, size) %}
  <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
{% endmacro %}

{# shortcuts.html #}

{% macro wrapped_input(name, value, type, size) %}
    {% import "forms.html" as forms %}
    <div class="field">
        {{ forms.input(name, value, type, size) }}
    </div>
{% endmacro %}

filter标签
就是给整个区块使用过滤器

{% filter upper %} 
    This text becomes uppercase 
{% endfilter %} 
{% filter upper %}
    This text becomes uppercase
{% endfilter %}
{% filter lower|escape %} 
    <strong>SOME TEXT</strong> 
{% endfilter %}
