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

Recommended Posts

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.

      Fala galera, tudo bem?
       
      Tenho o seguinte codigo:
       
       class Data {
      public static function ExibirTempoDecorrido($date)
      {
          if(empty($date))
          {
              return "Informe a data";
          }
          $periodos = array("segundo", "minuto", "hora", "dia", "semana", "mês", "ano", "década");
          $duracao = array("60","60","24","7","4.35","12","10");
          $agora = time();
          $unix_data = strtotime($date);
          // check validity of date
          if(empty($unix_data))
          {  
              return "Bad date";
          }
          // is it future date or past date
          if($agora > $unix_data) 
          {  
              $diferenca     = $agora - $unix_data;
              $tempo         = "atrás";
          } 
          else 
          {
              $diferenca     = $unix_data - $agora;
              $tempo         = "agora";
          }
          for($j = 0; $diferenca >= $duracao[$j] && $j < count($duracao)-1; $j++) 
          {
              $diferenca /= $duracao[$j];
          }
          $diferenca = round($diferenca);
          if($diferenca != 1) 
          {
              $periodos[$j].= "s";
          }
          return "$diferenca $periodos[$j] {$tempo}";
      }
      }
       
      Funciona redondinho se o valor retornado for de algumas horas, mas...
      Quando passa de dois meses, ele retorna a palavra mess. Deve ser por conta dessa linha
      if($diferenca != 1) 
          {
              $periodos[$j].= "s";
          }
       
      Quero que modre:
       
      2 meses atrás
      e não
      2 mess atrás.
       
      Espero que tenham entendido.
       
      Valeu

      Boa tarde pessoal, tudo bem ?
       
      Eu uso o tinymce para cadastro de textos no meu siite, porém, quero fazer um sistema para que os colunistas possam fazer o próprio post.
      O problema do tinymce, é que ele mantém a formatação do texto copiado, como tamanho de fonts, negritos, etc... Quero que o usuário cole o texto e a própria textarea limpe a formatação para que ele formate como quiser.
       
      A pergunta é:
       
      O tinymce tem uma opção para desabilitar a formatação quando um texto é colocado?
      Tem alguma função via java ou php para retirar a formatação assim que o texto é colado?
      Ou é melhor usar um outro editor?
       
      Agradeço deste já.

      Olá a todos!
      Tenho uma pagina que possui uma DIV onde coloquei uma pagina PHP.
      Uso a função setInterval para atualizar a pagina inclusa dentro da DIV.
      O problema é que ao acessar o site , a DIV só me mostra a pagina inclusa somente quando completo o primeiro minuto.
      Preciso que a pagina inclusa já inicie carregada
       
      Meu código JavaScript e a DIV com a pagina PHP
       
      <script> function atualiza(){ var url = 'direita.php'; $.get(url, function(dataReturn) { $('#direita').html(dataReturn); }); } setInterval("atualiza()",60000); </script> <div> <span id="direita"></span> </div>
