I have a project, I use Composer and i import many thing by it... i require the autoload.php in my index (the root of project) and istead Slim, Mongo, Twig work very well. But when I call a class of Respect/Validation it doens't work; if I simply use Respect/Validation the error is:
Class 'Respect\Validation\Validator' not found in (path of file when i need it).
if I try to require also here the autoload.php the errors are:
**Warning**: require_once(vendor/autoload.php): failed to open stream: No such file or directory in (path of file when i need it)
**Fatal error**: require_once(): Failed opening required 'vendor/autoload.php' (include_path='.;C:\xampp\php\PEAR') in (path of file when i need it)
If you are using a file (file.php) in a particular directory like this:
/app/controller/validation
and your vendor directory is in the base path of the project, you need to include the relative path to vendor directory:
../../../vendor/autoload.php
