[solved] BlockCategories smarty variable doesnt work

[romain34]

Hi all,

 

I begin to developp website with prestashop and i am currently encountering an issue that i can not resolve by myself.

 

I have created and assignated a new smarty variable in the blockcategories.php file and i can't get it in the matching tpl file.

 

In blockcategories.tpl, whatever if i try to access to this variable with {$variable|print_r} or with a foreach loop, i only get a '0' value displayed on page. I am sure that my array variable is not empty as i displayed it in the php file.

 

With the smart debug console, i don't see my variable.

 

Here is a sample of my code which has exactly the same behaviour:

 

Blockcategories.php:

 

$arr = array(1, 2, 3);

$this->smarty->assign('test', $arr);

 

 

Blockcategories.tpl:

 

{foreach from=$test item= resultat}

{$resultat}

{/foreach}

 

I sincerely hope that someone willbe able to helm me ...

 

Regards,

 

Romain

maybe try to use other way to assign new variable:

 

 

$arr = array(1, 2, 3);
global $smarty;
$smarty->assign(array('variable'=>$arr));

Ok, thank's Vekia.

 

Now i can see the variable in the smarty console. But, i can't access to its content in the blockCategries.tpl file.

 

Any idea ?

 

Thank's

you creating this assign function in correct function displayYOUR_HOOK(){}

 

?

Many thank's .... It works !

 

I had to switch my code in the function hookHeader() instead of function hookLeftColumn() .

 

But i don't really understand : the block categories is dislayed in the left column on my page, so why to declare this smarty in the header display function?

 

Thank's

to be honest, i dont exactly know why it isnt work well with correct hook ... Maybe some other code isnt working well, i dont know
