php - Codeigniter无法上传文件

Question

我想用结构更新 mysql 上的数据|咬|纳玛 |路径1 |路径2 |

我想更改上传的文件名这是我的 View 代码

<form class="form-horizontal" method="post" action="<?php echo base_url()?>index.php/c_main/uploadFile" enctype="multipart/form-data">
  <div class="form-group">
    <label for="exampleInputFile">Berkas 1</label>
            <input type="hidden" name="nip" id="nipUpload" value="">
            <input type="file" class="filestyle" name="berkas[]" data-buttonText="Find file" id="berkas[]">
            <p class="help-block">Example block-level help text here.</p>
  </div>
  <div class="form-group">
            <label for="exampleInputFile">Berkas 2</label>
            <input type="file" class="filestyle" name="berkas[]" data-buttonText="Find file" id="berkas[]">
            <p class="help-block">Example block-level help text here.</p>
  </div>

          <div class="row">
                <button type="submit" class="btn btn-default">Upload File</button>
          </div>
</form>

this is my controller code

function uploadFile()
        {
            $nip = $_POST['nip'];

            $number_of_files = sizeof($_FILES['berkas']['tmp_name']);

            $cek = 0;
            for($i=0;$i<$number_of_files;$i++)
            {
                $namaBerkas[$i] = $nip."-".($i+1).".jpg";

                $config['upload_path']          = base_url().'assets/upload/';
                $config['allowed_types']        = 'gif|jpg|png';
                $config['max_size']             = 1000;
                $config['max_width']            = 2024;
                $config['max_height']           = 1200;
                $config['file_name']            = $namaBerkas;

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

                if ($this->upload->do_upload()){
                    $cek = $cek +1;
                }
                print_r($config);
                echo $cek;
                die();

            }

            if($cek == 2){
                if($this->m_main->uploadFile($nip,$namaBerkas[0],[1])){
                    echo "<script> alert ('Upload Berkas Berhasi!');</script>";
                    redirect('admin/C_main/beranda');
                }
            }

        }

这是我的模型

function upload_file($nip, $berkas1, $berkas2){
            $sql = "update daftar set PATH1 = $berkas1, PATH2 = $berkas2 WHERE NIP = $nip";
            return $this->db2->query($sql);
        }

上面代码的输出是:您没有选择要上传的文件。

我认为问题是您有两个相同的表单字段。试试这个

<form class="form-horizontal" method="post" action="<?php echo base_url()?>index.php/c_main/uploadFile" enctype="multipart/form-data">
<div class="form-group">
<label for="exampleInputFile">Berkas 1</label>
<input type="hidden" name="nip" id="nipUpload" value="">
<input type="file" class="filestyle" name="berkas[]" data-buttonText="Find file" id="berkas[]">
<p class="help-block">Example block-level help text here.</p>
</div>
<div class="row">
<button type="submit" class="btn btn-default">Upload File</button>
</div>
</form>
