php - TWIG：从字符串中修剪两个字符

Answer 1

Use php str_replace

str_replace([",", "₹"], "", $str);

replace for twig

{% if foo |replace({'₹':'', ',':''}) |number_format > 3000 %}

So how you would ideally do it would be pass in just a regular integer to your twig template, do the comparison & then if you need to display the whole string on the page, prefix the number_format to get the comma and if you wish decimal places.

Answer 2

正如评论中提到的，这不是视图的工作。但replace过滤器可以这样做：

{% if foo |replace({'₹':'', ',':''}) > 3000 %}

您不想使用number_format过滤器，因为这只会重新引入标点符号。
