Remember the 3 pitfalls of CI2.0 shopping cart category

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

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

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

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

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