If you checked my last post, you will have read about how to get all your old ZF1 classes autoloading in your new shiny ZF2 project. However, the DB settings from your application.ini won’t have been set, and so you’ll get a 500 response with No Db Adapter. Not a problem. We just create the db adapter ourselves and tell Zend_Db that it is the default.
I’ve put this in the ZF2 index.php just before the last line, Zend\Mvc\Application::init($appConfig)->run();
//Set up ZF1 DB
$params = array(
'host' => '127.0.0.1',
'username' => 'xxx',
'password' => 'xxx',
'dbname' => 'xxx'
$adapter = Zend_Db::factory('Pdo_Mysql',$params);
Now your autoloading ZF1 DB classes wont freak out, and should connect no problem!
I’ve started using Apigility for building my API for my mobile app of my site! It’s incredible, you have to try it!
Anyway, I wanted to be able to load my existing code into ZF2 so I didn’t have to reinvent the wheel.
My API is running on a subdomain in an api sub folder within the main project. In the api folder, I made a folder called library. Then I symlinked my Zend and other folders from my ZF1 project into it (this may not have been necessary, but I didn’t want ../.. relative link type stuff in my composer.json)
:~/www/site/api/library$ ln -s ../../application/library/Zend Zend
:~/www/site/api/library$ ln -s ../../application/library/ZendX ZendX
:~/www/site/api/library$ ln -s ../../application/library/TTB TTB
:~/www/site/api/library$ ln -s ../../application/library/AA AA
Next you need to do is tell composer.json about your libraries.
Finally get composer generating autoload files. Type in:
~/www/site/api$ composer dump-autoload
Generating autoload files
And thats it! You should now be able to call things like:
$awesome = new Zend_Pdf();
$old_skool = new AA_Old_Skool_Class();
