Can't access image link

[SonoguN]

Hi I am very new to Prestashop and am trying to create a module that will create a PDF of a product. Everything seems to be working fine except I cannot seem to access the image url.. I can get the image ID, but getimagelink() does nor work and keeps giving me the following error: "Notice: Undefined property: Dispatcher::$allow in C:\wamp\www\albert_menes\classes\Link.php on line 381" and also " Notice: Undefined property: Dispatcher::$protocol_content in C:\wamp\www\albert_menes\classes\Link.php on line 387" I am no doubt doing something wrong so if someone could point out how to fix this I would be really grateful. Thanks

$link->getImageLink($name, $ids, $type = null)

 

$name rewrite link of the image

$ids id part of the image filename - can be "id_product-id_image" (legacy support, recommended) or "id_image" (new)

$type

Thanks for the feedback.. hmm I thought that I was pulling all this in correctly. Still couldn't get it to work.. Got it to work in the .tpl file but it just breaks if I try access it in the .php controller. Need to get the url to pass to the pdf class.

 

I have managed to fix this using a work around.. passed the link from the product page via a url parameter, but would prefer to access it in the controller.

 

cheers much appreciated

the available function inside Link class is not a static function

So you should call the function this way $link->availableClassFunction() instead Link::availableClassFunction()

 

And remember, you should load the link object before use, except the link object is already there somehow in your file.

Maybe it's already there in context object of your file, so you can call $this->context->link->availableClassFunction();

 

Link object can be load like this in your controller file

$link = new Link(); 

OR

$link = $this->context->link;

 

You can do a debugging to make sure link object is already there or not :

// debugging
if(Validate::isLoadedObject($link)) {
   echo '$link object available';
   d($link);
}
elseif(Validate::isLoadedObject($this->context->link)) {
   echo 'context link available';
   d($this->context->link);
}
else
   d('link object not available yet');

If link object not available yet, and you need full URL as result, you should add protocol/host variable when loading link object

$protocol_link = (Configuration::get('PS_SSL_ENABLED') || Tools::usingSecureMode()) ? 'https://' : 'http://';
$useSSL = ((isset($this->ssl) && $this->ssl && Configuration::get('PS_SSL_ENABLED')) || Tools::usingSecureMode()) ? true : false;
$protocol_content = ($useSSL) ? 'https://' : 'http://';
$link = new Link($protocol_link, $protocol_content);

Awesome, this worked!

 

$this->context->link->availableClassFunction()

 

Thank so much for your help!!

Understanding this will help a lot for future development.

 

Cheers
