link->getCategoryLink throws a strange warning

Hi, with this line of code:

 

p($link->getCategoryLink(new Category(3)));

 

I get the requested permalink, but also this warning:

 

Warning: trim() expects parameter 1 to be string, array given in [...]/classes/Tools.php on line 981

 

So, what's the matter here? If I look at the Link::getCategoryLink() source, I see that I must pass the category Object, since the category ID (that instead doesn't throw any warning) is deprecated.

 

Any idea?

I believe these are your issues

 

$params['meta_keywords'] = Tools::str2url($category->meta_keywords);

$params['meta_title'] = Tools::str2url($category->meta_title);

 

Can you try to dump those 2 variables before those 2 lines? (they're in the getcategorylink funcion)

Yes, the dump is something like this:

 

array(1) {   [1]=>   string(0) "" }

 

So they're array not string.

 

Though, it's just prestashop output. getCategoryLink wants a category object, and a category object features those properties as array, not string. I guess it's maybe a little bug? For now I'll continue to use the ID instead, even if it's officially deprecated.

 

Thank you!
