使用多个输入字段上传多个文件

我认为有几个输入字段是这样的


<head>

<title>Upload Form</title>

</head>

<body>

<?php echo form_open_multipart('info/normal_upload');?>


<input type="file" name="one" size="20" />

<input type="file" name="two" size="30" />

<input type="file" name="three" size="40" />


<br /><br />

<input type="submit" value="upload" />


</form>


</body>

</html>

我正在像这样上传文件


        $config['upload_path'] = realpath(FCPATH.'uploads');

        $config['allowed_types']= "gif|jpg|png|jpeg|pdf";

        $config['overwrite'] = TRUE;

        $config['max_size'] = "2048000"; 

        $config['max_height'] = "5000";

        $config['max_width'] = "5000";

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

        


        if ( ! $this->upload->do_upload('one'))

        {

                $error = array('error' => $this->upload->display_errors());


                $this->load->view('normal_upload', $error);

        }

         if ( ! $this->upload->do_upload('two'))

        {

                $error = array('error' => $this->upload->display_errors());


                //$this->load->view('normal_upload', $error);

        }

         if ( ! $this->upload->do_upload('three'))

        {

                $error = array('error' => $this->upload->display_errors());


                //$this->load->view('normal_upload', $error);

        }

        else

        {

          $data = array('upload_data' => $this->upload->data());

          echo $data['upload_data']['full_path'].'<br/>';


          //$this->load->view('normal_upload', $data);

                

        }

我想获取所有上传文件的文件名、路径。如果我在所有表单字段中选择文件，文件将被上传，但是：


echo $data['upload_data']['full_path'].'<br/>';

只能获取一个文件路径。如何获取文件路径并重命名上传的文件？

使用 $this->load->library('upload', $config); 加载库；当您只上传一个文件时有效。但是，当您上传多个文件时，您需要使用配置重新初始化库。就像这样：$this->load->library('upload');$this->upload->initialize($config);if ( ! $this->upload->do_upload('one')){        $error = array('error' => $this->upload->display_errors());        $this->load->view('normal_upload', $error);}$data['one'] = array('upload_data' => $this->upload->data());$this->upload->initialize($config); if ( ! $this->upload->do_upload('two')){        $error = array('error' => $this->upload->display_errors());        //$this->load->view('normal_upload', $error);} $data['two'] = array('upload_data' => $this->upload->data()); $this->upload->initialize($config); if ( ! $this->upload->do_upload('three')){        $error = array('error' => $this->upload->display_errors());        //$this->load->view('normal_upload', $error);}$data['three'] = array('upload_data' => $this->upload->data());然后您可以使用以下命令访问文件数据：$data['one']['upload_data']['full_path'];$data['two']['upload_data']['full_path'];$data['three']['upload_data']['full_path'];

事实证明它并不是那么简单。下面的代码：仅上传图像文件和 pdf，仅允许上传图像和 pdf重命名上传的文件删除上传文件中的所有空格public function normal_upload(){&nbsp; &nbsp; $uploadLocation = "uploads/";&nbsp; &nbsp; $uploadMainTo = null;&nbsp; &nbsp; if(isset($_FILES['MainImage'])){&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; $path = $_FILES['MainImage']['name']; // file means your input type file name&nbsp; &nbsp; $ext = pathinfo($path, PATHINFO_EXTENSION);&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; if ($ext=="jpg" OR $ext=="jpeg" OR $ext=="gif" OR $ext=="png" OR $ext=="pdf") {&nbsp; &nbsp; &nbsp; &nbsp; echo "Upload successful";&nbsp; &nbsp; }else{&nbsp; &nbsp; &nbsp; &nbsp; // your invalid code here like...&nbsp; &nbsp; &nbsp; &nbsp; echo "Invalid image format.
