[Bug] 1.6.1.0 product unavailable when clicking reviews

[Administratоr]

Hello, I upgraded to 1.6.1.0 yesterday. I noticed an error - when I click on a product, all goes fine: I go to the product view page. There, I can add the product to my shopping cart.

 

Still on the product view page, when I click "read reviews" (or something similar in english), this "#idtab5" gets appended to the url and then scrolls to the reviews section. This is all expected behaviour, however the shopping cart button has now disappeared and there is an error notice "this product is not available in this configuration" (or something similar in english).

 

What I tried: ctrl+F5 doesn't help.

 

I believe this has something to do with the (new?) way prestashop handles links, apparently combinations will now work via # urls? Not sure, just a guess. Anyway this breaks real anchors and can create design issues.

 

This really breaks my site because I want people to be able to add stuff to the cart no matter what!

 

Any way to circumvent this behaviour? Patches? Thanks!

bump - anyting at all?

Another bump. I think this is important. How about you?

[Massi-X]

You have to go in the productcomments.js file of productreviews (can be found in your theme or module directory under the js folder) and change this:

$(document).on('click', 'a[href=#idTab5]', function(){
		var target = this.hash,
		$target = jQuery(target);
		jQuery('html, body').stop().animate({ 'scrollTop': $target.offset().top - 180 }, 500, 'swing');
		$('*[id^="idTab"]').addClass('block_hidden_only_for_screen');
		$('div#idTab5').removeClass('block_hidden_only_for_screen');
		$('ul#more_info_tabs a[href^="#idTab"]').removeClass('selected');
		$('a[href="#idTab5"]').addClass('selected');
	});

To this:

$(document).on('click', 'a[href=#idTab5]', function(e){
		e.preventDefault();
		e.stopImmediatePropagation();
		var target = this.hash,
		$target = jQuery(target);
		jQuery('html, body').stop().animate({ 'scrollTop': $target.offset().top - 180 }, 500, 'swing');
		$('*[id^="idTab"]').addClass('block_hidden_only_for_screen');
		$('div#idTab5').removeClass('block_hidden_only_for_screen');
		$('ul#more_info_tabs a[href^="#idTab"]').removeClass('selected');
		$('a[href="#idTab5"]').addClass('selected');
	});

Done!

Hi,

 

I'm currently facing the same problem. I'm using Prestashop 1.6.1.3 and I can't find the #idTab5 behavior Massi-X is talking about. I checked /modules/productcomments/js/productcomments.js but nothing here.

Seems like something is going wrong with the checkUrl() function of the global product.js JavaScript file.

 

Any help is appreciated. This bug is really annoying for the users.

Hello,

I made a quick solution for this:

1. Edit file productcomments.js (in themes/**your-theme**/js/modules/productcomments.js)

Comment out the following code:
 

	$(document).on('click', 'a[href=#idTab5]', function(e){
		$('*[id^="idTab"]').addClass('block_hidden_only_for_screen');
		$('div#idTab5').removeClass('block_hidden_only_for_screen');
		$('ul#more_info_tabs a[href^="#idTab"]').removeClass('selected');
		$('a[href="#idTab5"]').addClass('selected');
	});

Like this:

/*
	$(document).on('click', 'a[href=#idTab5]', function(e){
		$('*[id^="idTab"]').addClass('block_hidden_only_for_screen');
		$('div#idTab5').removeClass('block_hidden_only_for_screen');
		$('ul#more_info_tabs a[href^="#idTab"]').removeClass('selected');
		$('a[href="#idTab5"]').addClass('selected');
	});

*/

After this add following code:
 

$("#product_comments_block_extra .reviews").click(function() {
    $('html,body').animate({
        scrollTop: $("#idTab5").offset().top},
        'slow');
});

The file should now look like this:

	});
});

function productcommentRefreshPage()

2. Edit file productcomments-extra.tpl (in themes/**your-theme**/modules/productcomments/productcomments-extra.tpl)

[Administratоr]

I have solved the bug myself. The problem was this: when you click the "read reviews" link below the short description of the product, the page URL changes to #idTab5 --> This makes the page scroll to the "reviews" tab, where you can read the reviews. The thing is however, that this also somehow triggers the system to think the user has made a CHOICE (e.g. clicked an option/variation/combination).

 

So I checked the /your-theme/js/product.js file, scrolled to the function findCombination(), and added the following code somewhere after the choice array was defined:

// If choice empty -> return (avoiding the "combination doesn't exist error" when clicking anchor tags)
if(choice.length <= 0){ return; }

So now my products.js file looks like this.

So basically the choice array gets defined and various checks are performed to determine the combination the user has selected. The problem is, there is NEVER a check whether the choice was empty or not! Now this is fixed. This code should imho be reviewed by the devs and if correct, included in the source.
