twig striptags and html special chars

Question

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 surrou

Answer 1

Arf, I finally found it :

I am using a custom twig filter that just applies a php function:

<span>{{ organization.shortDescription ?: php('html_entity_decode',organization.content|striptags|truncate(200, '...')) }}</span>

Now it renders correctly

My php extension:

<?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';
    }
}

Answer 2

I had a similar issue, this worked for me:

{{ variable |convert_encoding('UTF-8', 'HTML-ENTITIES') | raw }}

Answer 3

I had the same problem, I resolved it byt this function below, using strip_tags.

<?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';
    }
}

Answer 4

I was trying some of, among others, these answers:

{{ 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 raw filter on the end of all operations, i.e:

{{ organization.content|striptags|truncate(200, '...')|raw }}

Answer 5

If it could help someone else, here is my solution

{{ 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

EDIT November 2017

If you want to keep the "\n" break lines combined with a truncate, you can do

{{ organization.content|striptags|truncate(140, true, '...')|raw|nl2br }}
