Passing smarty var to home page,not working

[omerdavid]

Hello

I am trying to pass smarty variable from controller to tpl,when i am using override in the categoryController i can use this variable in the product-list.tpl,but when i tried to use it in my home-page that  also uses the product-list.tpl it will not work,

i tried to assign, in the indexController.php--didn't work,

also if when override the  productController.php i dont see the assigned variable in the product.tpl ,only when codding the productControllerCore directly i can use the variable in the product.tpl .

 

the Variable i am trying to pass is

$this->context->smarty->assign(array(
           'BASE_ROOT_DIR' =>  _PS_ROOT_DIR_));

Thanx

Anybody ?

Think you can use this in tpl file

$smarty.const._PS_ROOT_DIR_

https://github.com/PrestaShop/PrestaShop/blob/fbe174506f99ae0d79e03ac06cd3e9420e94f6a3/themes/default-bootstrap/modules/blocklayered/blocklayered.tpl#L90

 

But in general, if you want to have some variable in several controllers you can override FrontController but watch where you assign

variable and when you call parent function. Also do not forget to clear cache.

Thanx a lot ,it  works good,but steel i wanted to know which specific controller is used with product-list  home-page  ? and how come when using product-list.tpl in category page the var exist and when  home-page using product-list.tpl there is no var? 

[razaro]

On homepage product-list.tpl is used by modules: homefeatured, blocknewproducts and beatsellers.

In controller i am adding the var assign in function initContent(),what is the right  function to assign var, in moduls ?

[razaro]

It depends on module, how it is organised, but usually you need to add it to some displayHookHome that already exists.

Note that in latest versions you can override modules (its php files) too, there is one topic on forum with some explanation.

 

Also try to not use overrides when you do not need it, and check if it is possible to do task in different way. Maybe some custom module

that hooks into some existing hook in product-list.tpl, or even add your own custom hook.

for example, i would like to add suppliers to orders in BO ,while trying to do so i understood that i need to override the adminOrderController.php and to add _select and _join,

how do i know when it will be better to use module rather than override ?

[razaro]

Note that is different question and you should make new topic for it.

 

But if you make changes to just one store you can use just overrides.

If you need more functionality and options you can make a module that

on install overrides that adminOrderController. Just note that using overrides

can get to some issues, for example when few modules wants to override same 

controller. Then conflict appears and you have to manually combine code.

 

Also check PrestaShop documentation and github, think there are few new hooks 

added for order page, so you can hook module to it and show suppliers like that.
