str_replace in Twig

Question

I want to do a simple str_replace in my twig template. I'm new to twig and probably I need to add new filter or sth like that or to use existing. How can I do this? Where can I find list of filters available?

What exactly do you want to do? There are a number of filters and some HTML escaping built in to twig already: http://www.twig-project.org/doc/templates.html — CamelBlues, Feb 22 '11 at 14:34

Use this to replace | with - and replace , width .:

{{age|replace({'|': "-", "," : "."})}}

Example input 31|60, comes out as 31-60.

Thanks, this is non-obvious in the current documentation – Prinsig Jun 29 '16 at 09:32

@Prinsig indeed. From the documentation I thought you could only replace placeholders. – ohvitorino Aug 24 '17 at 07:33

To replace a string which is stored in twig variables:

{% set twig_content_variable= 'Testing to replace content'%}
{% set replace_value_var= 'Testing' %}
{% set replace_with_value_var = 'Testing complete' %} 

{{ twig_content_variable|replace({ (replace_value_var): replace_with_value_var }) }}

Thank you! The parentheses around `replace_value_var` are missing from the documentation. – Nate Cook Sep 01 '14 at 16:07

How to remove empty space? – Guru Dec 29 '15 at 07:35
@Guru like this {{ "apples and carrots"|replace(' ', '') }} – Microcipcip Dec 05 '16 at 17:06

The documentation simply doesn't mention the parentheses because you don't need them. – Capsule Dec 14 '17 at 03:26
@Capsule you'd think so, but for some strange reason, it doesn't replace without them, they don't have to be for explicit string key like `'some'`, but has to be around variable (probably some internal string=>key resolution) – jave.web Feb 27 '23 at 14:33

When we add a single quote inside a single quote then we face the error.

solution for that:-

{{description|replace({"\'": "&#039"})|raw }}

Also, this could be useful for getting rid of (utf-8) language chars...

{{some_string|replace({'ć':'c','č':'c','š':'s','ž':'z','đ':'d','Ć':'C','Č':'C','Š':'S','Ž':'Z','Đ':'D'})}}

How about: `iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text)`? – umpirsky Oct 15 '15 at 07:28

@umpirsky Hmmm, i think the code for twig goes something like this {{ data|convert_encoding('UTF-8', 'iso that you want') }}, but i'm not 100% sure – Denis Solakovic Oct 19 '15 at 08:57

Yes, mine was PHP. :) – umpirsky Oct 20 '15 at 08:07

Use this to replace . with "" , replace - width "" and : replace _ width "" :

"" = nothing or NULL

{{signature3.user.username|replace({'.': "", "-" : "","_":""})}}

input najim_el-guennouni, out as najimelguennouni.
