How to use composer packages in codeigniter?

I've followed this article: http://philsturgeon.co.uk/blog/2012/05/composer-with-codeigniter

But I get Fatal error: Class 'Buzz\Browser' not found.

What is missing from his post?

My controller or application isn't namespaced. I was hoping to just be able to use that one package in one controller's action in a non-namespaced framework.

Solution 1:

For CodeIgniter 3.x and composer, it's suggested to just set $config['composer_autoload'] to TRUE or a custom path in application/config/config.php.

It seems that CI assumes the vendor directory is within the application directory. That wasn't my case. I did the following:

$config['composer_autoload'] = 'vendor/autoload.php';

This is possible by just getting the order of loading correct:

/*
 * --------------------------------------------------------------------
 * LOAD THE BOOTSTRAP FILE
 * --------------------------------------------------------------------
 *
 * And away we go...
 *
 */
// Composer Autoloader
require FCPATH . 'vendor/autoload.php';

require_once BASEPATH.'core/CodeIgniter.php';

/* End of file index.php */

Solution 3:

Well in Codeigniter3.x you can easily do that by going into the application/config/config.php and look for this line

$config['composer_autoload'] = FALSE;

Make sure you set it to TRUE and right after it you require_once this:

require_once APPPATH.'vendor/autoload.php';

So you get something like this:

/*
|--------------------------------------------------------------------------
| Composer auto-loading
|--------------------------------------------------------------------------
|
| Enabling this setting will tell CodeIgniter to look for a Composer
| package auto-loader script in application/vendor/autoload.php.
|
|   $config['composer_autoload'] = TRUE;
|
| Or if you have your vendor/ directory located somewhere else, you
| can opt to set a specific path as well:
|
|   $config['composer_autoload'] = '/path/to/vendor/autoload.php';
|
| Note: This will NOT disable or override the CodeIgniter-specific
|   autoloading (application/config/autoload.php)
*/
$config['composer_autoload'] = TRUE;
require_once APPPATH.'vendor/autoload.php';

Just make sure you have your vendor folder in the application folder and you are good to go.

I recently found out that you can just set $config['composer_autoload'] = TRUE; and put your vendor folder in the application folder and that's it.

For those who would want your vendor folder outside the application folder. You can make it happen in this way: for example you want to place it in the root folder.

TIP: it has been described in the comment already

$config['composer_autoload'] = '/path/to/vendor/autoload.php';

/*
|--------------------------------------------------------------------------
| Composer auto-loading
|--------------------------------------------------------------------------
|
| Enabling this setting will tell CodeIgniter to look for a Composer
| package auto-loader script in application/vendor/autoload.php.
|
|   $config['composer_autoload'] = '/path/to/vendor/autoload.php';
|
| Note: This will NOT disable or override the CodeIgniter-specific
|   autoloading (application/config/autoload.php)
*/
$config['composer_autoload'] = FCPATH .'vendor/autoload.php';

Where FCPATH is codeigniter's defined constant for the root folder.

I guess this helps.
