Question

我很想用codeIgniter上传文件。我做错了什么，有人可以向我解释文件首映，以及如何在Windows上更改它。我应该只设置我上传文件的文件夹或专利文件夹。我的代码格式为

<div id="contact_box">
    <form id="form" enctype="multipart/form-data" name="form" action="<?php echo site_url('admin/clients/add_client');?>"  method="post" >
         Client Name: </br><input type="text" name="name" id="name"/> </br></br>
         LOgo: <input type="file" name="file" id="file"/> </br></br>

         <input type="submit"/>
    </form>    
</div>

和控制器

$this->load->library('upload');
$config['upload_path'] = './att/';
$config['allowed_types'] = 'png|jpg|bmp';
$this->upload->initialize($config);
$upload = $this->upload->do_upload();

我不知道我做错了什么我应该atdust htaccess文件吗？

$config['upload_path'] = './att/';

是否可能是这行错误的CodeIgniter文件夹的att文件夹子我应该检查文件前提。我为此文件夹添加了完全控制权。在控制器中我得到i print_r $_FILES['file']['name']时的结果，但文件夹中没有任何内容???

Answer 1

尝试这样的事情：

$this->upload->do_upload('file'); #The field name of the file you are trying to upload

Answer 2

尝试这样的事情：

$ this-＆gt; config = array（

              'upload_path'     => dirname($_SERVER["SCRIPT_FILENAME"])."/att/",
              'upload_url'      => base_url()."att/",
              'allowed_types'   => "png|jpg|bmp"

            );

$ this-＆gt; load-＆gt; library（＆＃39; upload＆＃39;，$ this-＆gt; config）;

如果（$这 - ＆GT; upload-＆GT; do_upload（））

{echo＆＃34;文件上传成功＆＃34 ;; }

否则 {echo＆＃34;文件上传失败＆＃34 ;;}

Answer 3

<input type="file" name="userfile1" class="form-control" />
<input type="file" name="userfile2" class="form-control" />

如果要多次使用它，请换个底盖等等

            $uploadOk = 1;
            $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
            // Check if image file is a actual image or fake image
