cloned table shipping in v.1.5.5

**earmsby** · 1 Jun 2016, 07:33 PM

Hi!

I'm in the process of upgrading a client's store from 1.5.4 to 1.5.5a. He uses cloned table rate shipping (table is cloned to usaground, usa2day, canadaair, etc.) I've done this many times and figured this wouldn't be much of a big deal to duplicate in this upgrade. But I noticed a key change in the table shipping module file. The line near the top of the file that used to say:

Code:

function table() {

now says:

Code:

function __construct() {

In the past when I cloned the table file for other methods, I would change

Code:

function table()

to

Code:

 functio usaground()

(or whatever the clone was). Should I change all the other instances of "table" but just not that first line?

I'm a bit confused!

Thanks!

I went ahead and cloned everything else but left the

Code:

 function __construct()

line and that seems to have worked. So, just reporting back in case anyone else is upgrading with cloned shipping files. :)

Unfortunately no one got back to you to explain why that was a good idea/method.

As of one or more of the earlier PHP 5.x versions, a class (something like a data structure that can have its own features applied to it) could be declared (initialized) using a function that more clearly indicates it's purpose. In this case to construct the class. Before this time, the class was initiated by a function having the same name as the class.

Currently this "older" method still works even in PHP 5.6, but in PHP 7.0 (ZC 1.5.5 is compatible with it), the use of the class to initiate the function is now considered a separate function and in certain conditions will cause an error. So in order to maintain compatibility of your code moving forward, use of __construct() just after the class is named is the "better" way to go.
