Question

I'm building simple app

This my controller

function post() {
    $config['file_name'] = 'produk_' . date('Y_m_d_H_i_s');
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|GIF|jpg|JPG|jpeg|JPEG|png|PNG';
    $config['max_size'] = '8000';
    $config['max_width'] = '4000';
    $config['max_height'] = '2000';
    $this->load->library('upload', $config);
    $this->upload->initialize($config);
    if (!$this->upload->do_upload()) {
        echo $this->upload->display_errors();
        echo 'Error Bos';
    } else {
        if ($this->_validation() === FALSE) {
            $this->session->set_flashdata('message', $this->message->message_error('Gagal Menambah Data'));
            redirect(base_url() . "admin/produk");
        } else {
            $data = $this->upload->data();
            $this->_create_thumbnail($data["file_name"]);
            $this->_create_mini($data["file_name"]);
            $data_adalah = $this->input->post();
            $data_adalah['GambarBesar'] = $data['file_name'];

            unset($data_adalah['submit']);
            $this->mproduk->add_record($data_adalah);
            $this->session->set_flashdata('message', $this->message->message_success('Berhasil Menambah Data'));
            redirect(base_url() . "admin/produk");
        }
    }
}

and this my view

<?php echo form_open_multipart('admin/produk/post'); ?>

<table style="width:500px">

Answer 1

尝试将$this->upload->do_upload()更改为$this->upload->do_upload('userfile')

You did not select a file to upload
