PHP não cadastra dados no Banco de Dados - Plugin Jquery FileUpload

Crislais · Janeiro 24, 2019

Olá Pessoal, pretendo utilizar o Plugin Jquery FileUpload, a documentação do mesmo está em: https://blueimp.github.io/jQuery-File-Upload/

Realizei a instalação do plugin no servidor local, conforme a documentação.

Surgiu a necessidade de cadastrar os dados no banco de dados, MySQL, e assim utilizei a seguinte documentação: https://github.com/blueimp/jQuery-File-Upload/wiki/PHP-MySQL-database-integration

O problema é: essa documentação não realiza o cadastro no banco como deveria, encontrei muitas pessoas na internet com o mesmo problema, e não encontrei algum artigo que ajudasse em português ou inglês. Estou a muitos dias tentando resolver esse problema, acredito que a função handle_file_upload não está funcionando, ou chamada corretamente, ou o botão Start upload

Segue meu código e a estrutura da tabela, que para facilitar o entendimento estou utilizando a mesma da documentação do GitHub

Desde já agradeço qualquer ajuda ou dica.
