How to delete white spaces of a text in twig?
提问by KubiRoazhon

First let's see what you tried and why that wasn't working:
首先让我们看看您尝试了什么以及为什么它不起作用：
- Spaceless: is not working because "Use the spaceless tag to remove whitespace betweenHTML tags, not whitespace withinHTML tags or whitespace in plain text" see spaceless documentation.
- Trim: is not working because "The trim filter strips whitespace (or other characters) from the beginningand endof a string" see trim documentation.
- Spaceless: 不起作用，因为“使用 spaceless 标签删除HTML 标签之间的空白，而不是HTML 标签内的空白或纯文本中的空白”，请参阅spaceless 文档。
- 修剪：不起作用，因为“修剪过滤器会从字符串的开头和结尾去除空格（或其他字符）”，请参阅修剪文档。
What you need to use is the following:
您需要使用的是以下内容：
{{ 'Some Text With Spaces'|replace({' ': ''}) }}
This will output:
这将输出：
SomeTextWithSpaces

You can also create your own filter to do that
您还可以创建自己的过滤器来做到这一点
Example :
例子 ：
class MyExtensions extends \Twig_Extension
{
public function getFilters()
{
return array(
new \Twig_SimpleFilter('removeWhiteSpace', array($this, 'removeWhiteSpace'), array('is_safe' => array('html'))),
);
}
public function removeWhiteSpace($string)
{
return preg_replace('/\s+/', '', $string);
}
}
Declare it as service :
将其声明为服务：
myextensions.twig_extension:
class: YourProject\YourBundle\Twig\MyExtensions
public: false
tags:
- { name: twig.extension }
And call it in yours twig template :
并在您的树枝模板中调用它：
{{ "Test remove white space"|removeWhiteSpace }}

For me this was not working when string contains non-breaking whitespaces:
对我来说，当字符串包含不间断空格时，这不起作用：
stringWithNonBreakingWhitespace|replace({' ':''}
To replace non-braking whitespace you have to use escape sequence:
要替换非制动空格，您必须使用转义序列：
stringWithNonBreakingWhitespace|replace({'\xc2\xa0':''}
