syntaxerror：意外的令牌

I have a problem in the opencart cart page , whenever the user want to remove an item from the cart the below massage is displayed

我在opencart购物车页面遇到问题,每当用户想要从购物车中取出商品时,都会显示下面的按摩

syntaxerror : unexpected token < in json at position 0
ok 
<pre>remove</pre>{"total":"0 item(s)-0.000 BD"}

i believe that

我相信

remove

should not be here , but unfortunately i couldn't find it in the files , any idea ?

3 个解决方案

#1

Seems that your output should be json format, however you're printing those <pre>remove</pre> as well, which makes your json invalid.

似乎你的输出应该是json格式,但是你也打印那些

remove ,这会使你的json无效。

Maybe You could try to use some grep in order to locate the file where those strings are coming from.

也许你可以尝试使用一些grep来找到那些字符串来自哪里的文件。

I know nothing about opencart... but your problem is that <pre>remove/pre> is "outside" of the json object, it must to be some thing like:

我对opencart一无所知......但你的问题是

remove / pre>是json对象的“外部”,它必须是这样的东西:

{"total":"0 item(s)-0.000 BD", "the_pre":"<pre>remove</pre>"}

What I think is that you have a php code that is making an echo when you make this request (ajax request?) before arrive to the json object output.

我认为你有一个PHP代码在你到达json对象输出之前发出这个请求(ajax请求?)时发出回声。

i found the solution to this problem

我找到了解决这个问题的方法

in system/library/cart.php

under : public function remove($cart_id) delete the follwing :

在:public function remove($ cart_id)删除以下内容:

   echo "<pre>";
            print_r("Remove");
            echo "</pre>"; )

that shall fix the problem

这将解决问题
