How to log or var_dump in prestashop?

[John Zaw]

I want to check the data information and I am wondering how to var_dump in prestashop.

And also how to do writing logs to a file and checking it later?

Into tpl files you can use {$var|@var_dump}

I insert this code {$var|@var_dump} to delivery-slip.tpl,  but how I can see these variables?  

I don't know where I can see these

Hello, for Smarty controllers use dump($you_variable) in this case you will see dump in the Symfony console.

Also is a very convenient method for TPL {dump($you_variable)}. You will see the dump as a structured block.
