我正在尝试使用DropZone js在一个请求中发送多个文件。
<script type="text/javascript">
Dropzone.autoDiscover = false;
var file= new Dropzone(".dropzone",{
url: any url,
method:"post",
paramName:"PhotoFiles",
addRemoveLinks:true,
autoProcessQueue: false
});
//Upload file onsubmit
$('#UploadMultiFiles').submit(function(){
file.processQueue();
});
file.on("sending",function(a,b,c){
a.token=Math.random();
c.append("token",a.token);
});
问题是我有相同形式的其他输入，这就是我使用onsubmit的原因，这些输入保存在表中，dropzone中的图像保存在另一个表中，两个表都有一个很多关系
控制器如：
public function university_offers($id){
$data['university_offer_name']=$this->input->post('university_offer_name');
$data['university_id_fk']=$this->input->post('university_id_fk');
$data['university_offer_details']=$this->input->post('university_offer_details');
if ($this->input->post('save')){
$data2['university_offer_id_fk'] = insertrecords('university_offers',$data);
$data2['university_id_fk'] = $data['university_id_fk'];
//when I put the next IF at the begining of the function it works but ofcourse without the other data fields that I need.
if(isset($_FILES) && $_FILES != null){
$data2['photo_name'] = upload_image('PhotoFiles');
insertrecords('university_offer_photos',$data2);
}
if (insertrecords('university_offer_photos',$data2)==true)
message('success','');
redirect('Admin/university_offers/0','refresh');
}
$data['view']="admin/universities/university_offers";
$this->load->view('index',$data);
}
我需要的是发送上传的文件并在controller中循环以将其保存在数据库中，而不是将每个文件发送到controller并保存。
修改
我的观点如下：

upload_image函数，我把它放在Helper中
function upload_image($file_name){
$CI =& get_instance();
$config['upload_path'] = 'public/uploads/images';
$config['allowed_types'] = 'gif|Gif|ico|ICO|jpg|JPG|jpeg|JPEG|BNG|png|PNG|bmp|BMP|WMV|wmv|MP3|mp3|FLV|flv|SWF|swf';
$config['max_size'] = '1024*8';
$config['encrypt_name']=true;
$CI->load->library('upload',$config);
if(! $CI->upload->do_upload($file_name)){
return false;
}else{
$datafile = $CI->upload->data();
thumb($datafile);
watermark($datafile);
return $datafile['file_name'];
}}
