Multiple files uploads unlimited files
多个文件上传无限文件
Database table(profile_images) column names are image_name(255,varcher), added_datetime(current timestamp)
数据库表( profile_images) 列名是image_name(255,varcher), added_datetime(current timestamp)
View
看法
<?php echo validation_errors();?>
<?php echo form_open_multipart('pages/multiple_files');?>
<p><input type="file" multiple="multiple" name="image_name[]" class="form-control" /></p>
<input type="submit" class="btn btn-success btn-block"/>

The problem is with the following line of code:
问题在于以下代码行：
<input type="file" class="file_upload2" name="userfile"/> //1
<input type="file" class="file_upload2" name="userfile"/> //2
<input type="file" class="file_upload2" name="userfile"/>//3
These all three have same name.
这三者同名。
To solve this there are two ways:
要解决这个问题，有两种方法：
Give diff name to all 3 input type file
为所有 3 个输入类型文件提供差异名称
Make a single input type file with its multiple file selection true and its name must be an array like:
使具有多个文件选择的单个输入类型文件为真，并且其名称必须是一个数组，例如：
<input type="file" name="filefield[]" multiple="multiple">
Make the following changes and try again.
进行以下更改并重试。

code of controller.
控制器代码。
public function upload_multiple($field_name,$path){
$this->load->library('upload');
$files = $_FILES;
$cpt = count($_FILES[$field_name]['name']);//count for number of image files
$image_name =array();
for($i=0; $i<$cpt; $i++)
{
$_FILES[$field_name]['name']= $files[$field_name]['name'][$i];
$_FILES[$field_name]['type']= $files[$field_name]['type'][$i];
$_FILES[$field_name]['tmp_name'] = $files[$field_name]['tmp_name'][$i];
$_FILES[$field_name]['error']= $files[$field_name]['error'][$i];
$_FILES[$field_name]['size'] = $files[$field_name]['size'][$i];
$this->upload->initialize($this->set_upload_options($path));
//for initalizing configuration for each image
$this->upload->do_upload($field_name);
$data = array('upload_data' => $this->upload->data());
$image_name[]=$data['upload_data']['file_name'];
//store file name into array
}
return $image_name;//all images name which is uploaded
}
public function set_upload_options($path)
{
$config = array();
$config['upload_path'] = $path;
$config['allowed_types'] = '*';
$config['overwrite'] = FALSE;
return $config;
}
call function
调用函数
$image_name=$this->upload_multiple('profile_image',$path=USER_OTHER);//we get all name of uploaded file in $image_name array.
