Get id_product in a hook from a module (Prestashop 1.7)

[GaShin]

I would like to recover the product id to be able to make my ajax call which needs the product id of the current product page. So I use the hook displayProductAdditionnalInfo which correctly returns the id_product to me but when I try to call it in another method, it returns me false. 

Can you help me? Is there a solution or an alternative ?

  

[Guest]

return Tools::getValue('id_product');
or
return $params['id_product'];

 

[Butch0071]

public function hookDisplayProductAdditionalInfo($params)
    {
// either:       
// return $params['id_product'];
//or 
return Tools::getValue('id_product');
        
  }

returns 0

Why theres is no id_product in $params?

 

[ventura]

$id_product = (int) $params['product']['id'];

$id_product = (int) $params['product']->id;

 

[Butch0071]

the thing is that the $params[product] look to be unset...

my $params looks like this:

Check if your module is registered on this hook inside positions.

Hi,

yest it is:

$this->registerHook('displayProductAdditionalInfo')

 

[Butch0071]

The module shows content (I can display content )in that place - it can't get product_it from $params

 

[WisQQ]

I meant check it inside backoffice if its actually registered. Because params from this hook are passed through template, you should also check template unless you are using default one.

[Butch0071]

OK - I have checked BO - in displayProductAdditionalInfo position - there is my module listed.

 

[Butch0071]

Now I think maybe I am using the wrong hook ? What hook should I use to display additional info on product list page - on product's miniature ?

Yes its a wrong hook, additional infos are productpage only. You could make your own hook or use some of these which are there by default:
displayProductListReviews
displayProductPriceBlock

But they are also used on Product Page.

If you wish to make your own hook and execute it you could do it like this:
Below is sample from my module displaying manufacturer image on product listing

    public function hookdisplayListingManufacturer($params){
        if($params['product']['id_manufacturer']>0){
            if(!isset($params['product']['manufacturer_image'])){
                $params['product']['manufacturer_image'] = $this->getManufacutrerImage($params['product']['id_manufacturer']);
            }
            $this->context->smarty->assign($params);
            return $this->fetch('module:'.$this->name.'/views/templates/front/listingmanufacturer.tpl');
        }
    }

Then you add hook inside your template/catalog/_partials/miniatures/product.tpl

{hook h='displayListingManufacturer' product=$product}

Calling hook inside template passes the product array so you are able to use it inside your custom hook. Ofcourse you need to register hook first.

[Butch0071]

Thank you - that is what I am going to do, I think I need  new hook. I will try that out now.

[Butch0071]

OK I have:

1 - register hook in my module: $this->registerHook('displayListingProductColorsNumber')

2 - I have checked - the module is hooked to that position

3 - I call hook : {hook h='displayListingProductColorsNumber' product=$product}
4- in function :

public function hookDisplayListingProductColorsNumber($params){

$languages = Language::getLanguages($active);

$this->context->smarty->assign(array( 
	'product_ID' => $params['product']['id'], 
	'languages' => $languages, 
	'default_language' => $this->context->employee->id_lang, 
));

}

I print_r($params) in function (and it displays content of $params in good place)- but I still see no product data

Array ( [product] =>

What am I missing?

It looks like the $params doesn't have product data.

you need to return template file and in your template you will be able to access it. I checked and i can var_dump params['product'].
Also you have error with product id.

	'product_ID' => $params['product']['id_product'], 

Also please explain the meaning on the languages, because you can acess it using 
 

$this->context->language->id

 

[Butch0071]

OK, thank you - I am returning :

return $this->display(__FILE__, 'views/templates/hook/productscolors.tpl');

And corrected to: (int)$params['id_product'];

I also try with new Product($params['id_product'])

 public function hookDisplayListingProductColorsNumber($params)
    {
	$productID = (int)$params['id_product'];
    
	$product = new Product($params['id_product']);

    $this->context->smarty->assign(array(
            'product_ID' => $productID,
            'prodID' => $product->id_product,
            'params' => $params,
        ));

     return $this->display(__FILE__, 'views/templates/hook/productscolors.tpl');
    }

and in productscolors.tpl I have:

Product ID: {$product_ID} ({$prodID})
<pre>
    {$params|@print_r}
</pre>

and on product list I see:

Product ID: 0()

Array ( [product] =>

...

[WisQQ]

You need to use $params['product']['id_product'] because $params have other variables than just product.
 

var_dump($params['product']['id_product']);

Copy it and paste inside your hook, then check if it will be displayed.

[Butch0071]

OK still I have empty product

from my tpl I get: NULL Product ID: ()

public function hookDisplayListingProductColorsNumber($params)
    {
	$productID = (int)$params['id_product'];
    
	$product = new Product($params['id_product']);

    var_dump($params['product']['id_product']);

    $this->context->smarty->assign(array(
            'product_ID' => $params['product']['id_product'],
            'prodID' => $product->id_product,
            'params' => $params,
        ));
        $this->context->smarty->assign($params);

        return $this->display(__FILE__, 'views/templates/hook/productscolors.tpl');
    }

and my tpl:

Product ID: {$product_ID}({$prodID})

I did copy your code and it works. Did you reinstall module after you changed to new hook?

[Butch0071]

when I var_dump($params) in hook function I see:
 

Array (

[product] =>
[smarty] =>
[cookie] => Cookie Object (....

[product] is empty....

Yes - I did.

[Butch0071]

I use: {hook h='displayListingProductColorsNumber' product=$product}

Well thats wreid. Which prestashop version are you using?

[Butch0071]

Yeah - I know -it's 8.0.4

 

[Butch0071]

I do not get it.

However when I hook on product page and :

$productID = $params['product']->name;

$this->context->smarty->assign(array(
    'product_ID' => $params['product']->id,
    'prodID' => $productID,
));

I got displayed Id and name - as supposed to be.

But when on product list - product is empty...

 

[WisQQ]

Well i tested your code on version 1.7.8.10 and it works.

[Butch0071]

In what .tpl have you placeed hook in 1.7.8.1?

For me it workds on product page but it doesn't on product list..

I need to check it on different version I quess or with different theme - maybe it messes something up.

Thank you for your help.

It looks that Shortcode widget of CE is unable to pass variables. (I was using it) Confusing was becouse it placeed hook in right position and was passing other data.

I modyfied template .tpl file - and it works as it should.

@WisQQ thanks again for your help.
