Creat global variable in module

[Skayfer]

Hi,

 

I write my module in which i have main class with a lot of fucntions. In almost every function i use var with number of result row:

 

$sql = "SELECT value FROM ps_configuration WHERE name LIKE '%MY_VALUE%'";
$result = Db::getInstance()->ExecuteS($sql);
$liczba_wierszy = DB::getInstance()->NumRows($result);

It works ok, but i would like write this module better, i dont want duplicate this code. I would like declare var $liczba_wierszy in one function and can use it in other functions in my module.

 

It is possible ?

 

Thanks for answers

Can anyone help ? Maybe i can use only context object ? It has this same functionality as gloabel var ?

I resolve my problem with

https://www.prestashop.com/forums/topic/156171-new-global-var/

, but i add modification. Cart expert not add global to first declaration of var. I test it and i must add global.

 

In step for other:

1. Outside main class i execute my code, declare "global $var", and assign result to "$var".

2. In each function in i want use this var, i must declare "global $var" and i can use "$var"

Hi global variables are forbidden in Prestashop modules however you can use below code format for variable to serve the same purpose.

 

$this->context->cookie->variablename
