Hochladen einer Datei in Codezeichen

Question

Ich erhalte eine Fehlermeldung You did not select a file to upload. beim Versuch, eine Datei hochzuladen, obwohl ich eine Datei zum Hochladen ausgewählt habe. Ich verwende eine Eingabedatei, die mit Bootstrap formatiert wurde. Ist das Problem damit? Ich habe die Anweisungen im Codeigniter-Benutzerhandbuch für Datei-Uploads befolgt. Kann mir bitte jemand helfen und den Fehler in meinem Code erkennen?

Danke

-Controller

public function create() 
{ 
    $config['upload_path']   = './uploads/'; 
    $config['allowed_types']  = 'gif|jpg|png'; 

    $this->load->library('upload', $config); 

    if (! $this->upload->do_upload('userfile')) 
    { 
      echo "Upload failed"; 
    } 
    else 
    { 
      $data = array('upload_data' => $this->upload->data()); 

    } 

    $data = array(
     'category' => $this->input->post('category'); 
     'name' => $this->input->post('recipename'), 
     'ingredients' => $this->input->post('ingredients'), 
     'directions' => $this->input->post('directions'), 
     'date' => date("Y/m/d") 

    ); 

    $this->model->insert($data); 
    redirect('', 'refresh'); 
}

Verwendung enctype in Tag Ihres HTML-Formulars.

<form action="<?php echo base_url();?>home/create" method="POST" role="form" enctype="multipart/form-data" > 

jetzt versuchen. es funktioniert. :)
