Easy way is copy this code to your php editor.
1、const ID, QTY for column name, it’s can change by yourself.
2、session only check isset.
3、array_push_after() maybe use not good way.
4、$item from CartItemtoArray(), this is array(). not class object.
5、getIndexOfEntry() try to get Array $container at index.
So use Array to control, no Object. Becasue I don’t know refrence, answer 1 and 2, How to create item add in cart.
When you use PDO, try to get
fetchAll(PDO::FETCH_ASSOC)
fetch(PDO::FETCH_ASSOC)
return is Array. This Array have rows, it’s mean :
array[0] = array[“field1”, “field2”, “field3”]
array[1] = array[“field1”, “field2”, “field3”]
……
array[10] = array[“field1”, “field2”, “field3”]
So get array index or row maybe not exist, when you try to get value, get error code.
You can try to make two function:
function ar_get($val, $ar){
return array_key_exists($val, $ar)?$ar[$val]:"";
}

PDO支持三种异常模式：
默认模式：PDO::ERRMODE_CLIENT
警告模式：PDO::ERRMODE_WARNING
异常模式：PDO::ERRMODE_EXCEPTION（推荐）
