CIFramework, the full name is CodeIgniter, I believe everyone is familiar with it, she is a small php framework, CI China official website documentation is also very comprehensive, and now ci4.0 also It's out and namespace has been added.

But I personally still prefer its 2.0 version.

The shopping cart function has been abandoned in later versions, but for students who are using ci2.0, I have summarized several bugs in the shopping cart class,

The code is as follows:

1. The judgment rules for product names are not friendly to Chinese. Often causing the addition to fail.

//log_message(&#39;error&#39;, &#39;An invalid name was submitted as the product name: &#39;.$items[&#39;name&#39;].&#39; The name can only contain alpha-numeric characters, dashes, underscores, colons, and spaces&#39;);
//return FALSE;

Copy after login

2. When the quantity remains unchanged, the shopping cart information cannot be modified

if ($this->_cart_contents[$items[&#39;rowid&#39;]][&#39;qty&#39;] == $items[&#39;qty&#39;])
{
    //return FALSE;
}

Copy after login

3. Only the quantity can be modified , cannot modify additional options options
Modify options additional options

$this->_cart_contents[$items[&#39;rowid&#39;]][&#39;qty&#39;] = $items[&#39;qty&#39;];
$this->_cart_contents[$items[&#39;rowid&#39;]][&#39;options&#39;] = $items[&#39;options&#39;];//here new?

Copy after login
