How to show kint debug info from a module on a page?

Question

In D8 I would like to display an array in the message part of a page. I did several things but could not get it work. What to do?

I installed the devel and kint modules.

I currently have changed in services.yml the settings into:

debug: true auto_reload: true cache: false

In the twig template I added

{{kint("I'm working from the page.html.twig")}}

This is displayed in the browser, so the current theme is displaying it which proves kint is working and the correct theme is used.

So now In my module file I have

$data_array = json_decode($data,true); kint($data_array); var_dump($data_array); return $data_array;

The var_dump gives a lot of data in a array. However the kint is not displayed.

How to get the kint displayed this array?

Which module file do you have this in and in which function? — sonfd

In a custom module I'm building myself in a class file which is autoloaded. — Justme

1. Where in what file and function exactly are you calling kint()? 2. Better use ksm() as it prints the variables in the messages container which by default should be placed at the top of the content area. — norman.lol

Try to take a look at this site it has a lot if useful information, print variables using kint.

They say that if you want to output in the message area then you shall use, ksm().

The solution is to run once before and to do the call different:

 kint_require();

so below code is running good

$data_array = json_decode($data,true); kint_require(); \kint::dump($data_array); return $data_array;
