问题描述
在树枝模板中，是否可以将内容附加到块?
In twig templating, is it possible to append content to a block?
例如，考虑下面的模板文件.
For example, consider the template files below.
layout.html.twig
layout.html.twig
<html>
<head>
<style>
{% block css %}{% endblock css %}
</style>
</head>
<body>
{% block content %}{% endblock content %}
</body>
</html>
inner.html.twig
inner.html.twig
{% block css %}
a { color: #fff; }
body { background: #f00; }
{% endblock css %}
{% block content %}
Some contents here...
{% include 'myWidget.html.twig' %}
{% endblock content %}
myWidget.html.twig
myWidget.html.twig
{% block css %}
div a { color: #777; }
{% endblock css %}
{% block content %}
<div><a>myWidget content here...</a></div>
{% endblock content %}
注意块 css.. 我想要完成的是我希望将块 css 的每个内容附加到 layout.html.twig 的 css 块.因此，最终结果应该是:
Notice the block css.. What I am trying to accomplish is that I want to have each content of the block css appended to the layout.html.twig's css block. Thus, the end result should be:
<html>
<head>
<style>
a { color: #fff; }
body { background: #f00; }
div a { color: #777; }
</style>
</head>
<body>
Some contents here...
<div><a>myWidget content here...</a></div>
</body>
</html>
推荐答案
这应该可以解决问题:
{% block css %}
{{ parent() }}
div a { color: #777; }
{% endblock css %}
{% block content %}
<div><a>myWidget content here...</a></div>
{% endblock content %}
