$uniqId = $this->input->post('U_I_T_Roll_No');
$config['upload_path'] = "./uploads/ProfileImages/";
        $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
        $config['max_size']  = '1024';
        $config['max_width']  = '1000';
        $config['max_height']  = '1000';
        /* Load the upload library */
        $this->load->library('upload', $config);
        /* Create the config for image library */
        /* (pretty self-explanatory) */
        $configThumb = array();
        $configThumb['image_library'] = 'gd2';
        $configThumb['source_image'] = '';
        $configThumb['create_thumb'] = FALSE;
        $configThumb['maintain_ratio'] = TRUE;
        /* Set the height and width or thumbs */
        /* Do not worry - CI is pretty smart in resizing */
        /* It will create the largest thumb that can fit in those dimensions */
        /* Thumbs will be saved in same upload dir but with a _thumb suffix */
        /* e.g. 'image.jpg' thumb would be called 'image_thumb.jpg' */
        $configThumb['width'] = 400;
        $configThumb['height'] = 400;
        /* Load the image library */
        $this->load->library('image_lib');

  /* We have 5 files to upload
   * If you want more - change the 6 below as needed
   */
  for($i = 1; $i < 5; $i++) {
    /* Handle the file upload */
    $upload = $this->upload->do_upload('image'.$i);
    /* File failed to upload - continue */
    if($upload === FALSE) continue;
    /* Get the data about the file */
    $data = $this->upload->data();

    $uploadedFiles[$i] = $data;
    /* If the file is an image - create a thumbnail */
    if($data['is_image'] == 1) {
        $configThumb['source_image'] = $data['full_path'];
        $this->image_lib->initialize($configThumb);
        $this->image_lib->resize();
    }
  }
  $S_image = $_FILES['image1']['name'];
  $F_image = $_FILES['image2']['name'];
  $M_image = $_FILES['image3']['name'];
  $LG_image = $_FILES['image4']['name'];
  $data5=array (
    'Uniq_Id' => $this->input->post('U_I_T_Roll_No'),

    'S_image' => $S_image,
    'F_image' => $F_image,
    'M_image' => $M_image,
    'LG_unique1' => $LG_image,
    );


  $this->InsertData->studentimageupload($data5);

上面的代码工作正常。我有 4 个要上传和正确上传的图像以及保存到数据库中的图像名称。问题是。

我想根据我的上传图片名称并将图片名称保存到数据库中。

【解决方案1】：

在$this->load->library('upload', $config);之前做这样的事情

将$this->load->library('upload', $config); 更改为$this->load->library('upload'); 并见下文

 for($i = 1; $i < 5; $i++) {
    $img=$_FILES['image'.$i]['name'];
    $new_name=NEW_NAME;
    $ext = strtolower(substr($img, strpos($img,'.'), strlen($img)-1));
    $file_name=$new_name.$ext;
    $config['file_name'] = $file_name;
$this->upload->initialize($config);
/* Handle the file upload */
$upload = $this->upload->do_upload('image'.$i);
/* File failed to upload - continue */
if($upload === FALSE) continue;
/* Get the data about the file */
$data = $this->upload->data();

$uploadedFiles[$i] = $data;
/* If the file is an image - create a thumbnail */
if($data['is_image'] == 1) {
    $configThumb['source_image'] = $data['full_path'];
    $this->image_lib->initialize($configThumb);
    $this->image_lib->resize();
    }
  }

【讨论】：

实际上我有 4 张图片要上传。你能把它放在数组中吗..以及如何命名所有五张图片..你只为一张图片上传编写了代码。我必须写e次..
对所有 5 个执行相同操作或创建一个函数。

【解决方案2】：

使用的名称是 $_FILES['image1']['name'] 中的任何名称。如果要更改它，可以在上传表单本身中更改它。如果这不是可取的，您必须致电rename() 然后更新

$S_image = $_FILES['image1']['name'];
$F_image = $_FILES['image2']['name'];
$M_image = $_FILES['image3']['name'];
$LG_image = $_FILES['image4']['name'];

在存储到数据库之前，将文件重命名为任何内容。

【解决方案3】：

我认为您可以通过在每次调用 do_upload 方法时初始化配置来解决重命名问题。

$config['file_name'] = YOUR_OWN_NAME

然后在你的 for 循环中初始化，就在你的 do_upload 调用之前

$this->upload->initialize($config);

【讨论】：

你能编辑代码并告诉我热门的事情吗？有一个 for 循环，我无法理解如何重命名多个图像。

【解决方案4】：

您应该能够在加载库后和上传文件之前指定“文件名”..

//make your config array.
$this->load->library('upload', $config);

for($i=1; $i < 5; $i++)
{
    $this->upload->set_filename($path, $filename);
    $upload = $this->upload->do_upload('image'. $i);
    //do whatever you want to do with the file.
}

到目前为止，我还没有在我的任何项目中使用它，但它应该会产生预期的结果。请告诉我，如果它不起作用..
