twig striptags and html special chars
提问by Sébastien
I am using twig to render a view and I am using the striptags filter to remove html tags. However, html special chars are now rendered as text as the whole element is surrounded by "". How can I either strip special chars or render them, while still using the striptags function ?
我正在使用 twig 来呈现视图，并且我正在使用 striptags 过滤器来删除 html 标签。但是，html 特殊字符现在呈现为文本，因为整个元素都被 "" 包围。如何在仍然使用 striptags 函数的同时去除特殊字符或呈现它们？
Example :
例子 ：
{{ organization.content|striptags(" >")|truncate(200, '...') }}
or
或者
{{ organization.content|striptags|truncate(200, '...') }}
Output:
输出：

If it could help someone else, here is my solution
如果它可以帮助别人，这是我的解决方案
{{ organization.content|striptags|convert_encoding('UTF-8', 'HTML-ENTITIES') }}
You can also add a trim filter to remove spaces before and after. And then, you truncate or slice your organization.content
您还可以添加修剪过滤器以删除前后的空格。然后，您截断或切片您的组织内容。

If you want to keep the "\n" break lines combined with a truncate, you can do
如果你想保留“\n”断行与截断相结合，你可以这样做
{{ organization.content|striptags|truncate(140, true, '...')|raw|nl2br }}
{{ organization.content|striptags|truncate(140, true, '...')|raw|nl2br }}

Arf, I finally found it :
Arf，我终于找到了：
I am using a custom twig filter that just applies a php function:
我正在使用仅应用 php 函数的自定义树枝过滤器：
<span>{{ organization.shortDescription ?: php('html_entity_decode',organization.content|striptags|truncate(200, '...')) }}</span>
Now it renders correctly
现在它正确呈现
My php extension:
我的 php 扩展：
<?php
namespace AppBundle\Extension;
class phpExtension extends \Twig_Extension
{
public function getFunctions()
{
return array(
new \Twig_SimpleFunction('php', array($this, 'getPhp')),
);
}
public function getPhp($function, $variable)
{
return $function($variable);
}
public function getName()
{
return 'php_extension';
}
}

I was trying some of, among others, these answers:
我正在尝试其中的一些答案：
{{ organization.content|striptags|truncate(200, true) }}
{{ organization.content|raw|striptags|truncate(200, true) }}
{{ organization.content|striptags|raw|truncate(200, true) }}
etc.
And still got strange characters in the final form. What helped me, is putting the rawfilter on the end of all operations, i.e:
并且在最终形式中仍然有奇怪的字符。帮助我的是将raw过滤器放在所有操作的末尾，即：
{{ organization.content|striptags|truncate(200, '...')|raw }}

I had the same problem, I resolved it byt this function below, using strip_tags.
我遇到了同样的问题，我通过下面的这个函数使用strip_tags解决了它。
<?php
namespace AppBundle\Extension;
class filterHtmlExtension extends \Twig_Extension
{
public function getFunctions()
{
return array(
new \Twig_SimpleFunction('stripHtmlTags', array($this, 'stripHtmlTags')),
);
}
public function stripHtmlTags($value)
{
$value_displayed = strip_tags($value);
return $value_displayed ;
}
public function getName()
{
return 'filter_html_extension';
}
}
