How can I "addJS" only to product pages?

[Pedro]

Hi,

I'm creating a module that needs to include certain script at the product page. I'm using the `hookDisplayFooterProduct` for that:

  public function hookDisplayFooterProduct()
  {
      $this->context->smarty->assign(
          array(
              'some_key' => Configuration::get('SOME_KEY'),
          )
      );
      $this->context->controller->addJS($this->_path.'view/js/something.js');
      return $this->display(__FILE__, 'html.tpl');
  }
What I'm trying to do is to include an html snippet at the 'displayFooterProduct' and to add a script to the bottom of the page. The html part works but the script is not included.

What I'm doing wrong? 
Thanks, 
 

Pedro

Try this

if(isset($this->context->controller->php_self)  && $this->context->controller->php_self == 'product')

It should only target the product page

Thanks @NemoPS,
I added that code to my hookDisplayHeader and it works (I know because I display something with var_dump) but I'm still unable to include include the script with

 $this->context->controller->registerJavascript('remote-mymodule-js', 'https://.....', ['position' => 'bottom', 'priority' => 150]);

I'm using prestashop 1.7. Is there any public API documentation for methods like registerJavascript?

The function is actually  $this->context->controller->addJS, I have never used that registerJavascript one honestly. I would recommend using a separate js instead of assigning it from php anyway.
If you really need to, use addJSDef();

I also tried with addJS without any success.
 

public function hookDisplayHeader()
{
    $this->context->controller->addJS($this->_path.'view/js/something.js');
    $this->context->smarty->assign(
        array(
            'my_module_key' => Configuration::get('my_module_key')
        )
    );
    return $this->display(__FILE__, 'test.tpl');
}

I expect to see something.js being included on the page. I'd disabled all caches, hit reset on the module. As a workaround I fixed my problem by adding a <script> tag with smarty.

That's the correct way to do it actually, but I think you need a / before view/
