在wordpress主题中使用composer并自动加载，“需要打开失败”

Question

So I've installed createsend-php for my theme via composer (I'm trying to learn how too use it) but can't get to the next stage.

I can see the API here - /wp-content/themes/wonkhe2-theme/vendor/campaign-monitor/createsend-php/

composer file seems right to me -

  "require": {
    "php": ">=5.4.0",
    "composer/installers": "~1.0",
    "campaignmonitor/createsend-php": ">=6.0"
  }

in /wp-content/themes/wonkhe2-theme/templates/content-signup-cm.php I've added require_once 'csrest_campaigns.php'

And that returns

Fatal error: require_once(): Failed opening required 'csrest_campaigns.php' (include_path='.:/Applications/MAMP/bin/php/php7.2.7/lib/php') in /wp-content/themes/wonkhe2-theme/templates/content-signup-cm.php on line 5

Should the require_once path be different? I thought autoloader would set the paths and namespaces.

Using composer is new to me so apologies if I'm misunderstanding but any help appreciated.

Answer 1

you should not require individual classes insalled by composer. instead, right at the start of your code:

require_once 'vendor/autoload.php';

then you can just start using objects;

use Some\Class\Or\Other;

$object = new Other();
