Twig: Php error

[ThibaultMartinPenbase]

Hello, I have a PHP error :

A PHP Error was encountered

Severity: Warning

Message: call_user_func() expects parameter 1 to be a valid callback, no array or string given

Filename: Extension/Escaper.php

Line Number: 72

Backtrace:

File: /mnt/c/Users/Thibault MARTIN/Documents/sites/Omega/vendor/twig/twig/lib/Twig/Extension/Escaper.php
Line: 72
Function: _error_handler

What's the value of https://github.com/twigphp/Twig/blob/2.x/lib/Twig/Extension/Escaper.php#L14 in your case and where does it get set from?

[ThibaultMartinPenbase]

I have private $defaultStrategy;

[Tobion]

I'm interested in the contents of this variable.

[ThibaultMartinPenbase]

Sorry,

The contents = TRUE

[Tobion]

So that's the problem. It must not be true. Can you debug now why it is true? You can check setDefaultStrategy and look in the backtrace.

[ThibaultMartinPenbase]

I used Codeigniter, no symfony

Closing as this is apparently not a Twig issue (perhaps a problem with the integration with Codeigniter, but we don't have any information that would help us find the issue).

im having same issue @ThibaultMartinPenbase did you found any fix for that?

[kraven30]

In Escaper.php for Codeigniter 3.*

Remplace te constructor by that

public function __construct($defaultStrategy = true){
if (true === $defaultStrategy) {
$defaultStrategy = 'html';
};
$this->setDefaultStrategy($defaultStrategy);
}

I you did it like me and got the CodeIgniter Twig implementation from an online tutorial and got this error, the solution is to change
$config['twig']['environment']['autoescape'] = TRUE;
to
$config['twig']['environment']['autoescape'] = 'html';
in the file ./application/config/twig.php as the solution from @kraven30 won't work when Twig is updated.
