Hi, dear Yii2 users!
I am facing a weird issue with Yii2, Twig and ArrayHelper.
As for demonstration purposes, let’s say:
-
I have defined a function in my twig section in config/web.php called var_dump (that does exactly as it seems )
-
My model [font="Courier New"]producer[/font] has a method [font="Courier New"]categories[/font] that returns an array of [font="Courier New"]Category[/font] object
So I have this in my view
{{ use ('yii\helpers\ArrayHelper') }}
{{ ArrayHelper.map(producer, 'id', 'name') | var_dump }}
That returns: [font="Courier New"]NULL[/font]
The only way I can have this working is defining a global in my Twig section’s config file this way:
'globals' => [
'array_helper' => '\yii\helpers\ArrayHelper',
],
And this this works!
{{ array_helper.map(producer, 'id', 'name') | var_dump }}
Why? What if I don’t want to define a global but an “use” in my view?
