Validation tutorial

It always execute it no matter what. It dosen't check if you posted any data. Haven't looked in the code in depth if you can actually fix it.

I added this to "fix" the problem. If it's a get request, don't try to look for $_POST and validate it.

PHP Code:

if(
    $this->request->getMethod() === 'get' ||
    ! $this->validate([])
)
{

}
else
{
    
} 


Thank you very much, this workaround does its job first. But there still has to be a reason why the tutorial methods didn't work.
I am interested in a clean, long-term solution
