用Symfony2多文件上传 [英] Multiple file upload with Symfony2

问题描述

我试图通过表单上传多个文件，但是我一次只能上传一个文件，而最后一个文件是在浏览器中标记的。有没有办法使用一个简单的形式上传Symfony2更多的图像？
这里是我用来标记多个文件的形式的树枝模板：

  {{form_widget（form.post_image，{'attr'：{'multiple'：'multiple'}}）}} 
 




我真的不知道什么是错的。检查你的模板（也许错误的enctype ...或名称attr missmatching）

首先尝试做一个单一文件上传，检查文档：

1. 档案字段类型


2. 如何处理文件上传与教义

一旦它工作，您必须编辑一些行。

1. 添加输入文件的多个属性。
   
2. append []在输入文件名属性的末尾（我的是
   创建... []因为我的表单类名称是创建，如果你是
   的createType它将是createType ... []）
   
3. init $文件作为一个数组。

I'm trying to upload multiple files via a form, but I can only upload one file at a time, the last one I mark in the browser. Is there a way to upload more images with Symfony2 using a simple form? Here is the twig template of the form I'm using to be able to mark more than one file:

{{ form_widget(form.post_image, { 'attr': {'multiple': 'multiple' }}) }} 

解决方案

No extra classes needed (except the gallery_manger service but the issue you describe happens before...)

I don't really know what's wrong. Check for your template (maybe wrong enctype... or name attr missmatching)

first try to do a single file upload, check the documentation:

1. file Field Type
2. How to handle File Uploads with Doctrine

Once it works, you have to edit some lines.

1. add input file multiple attribute.
2. append [] at the end of the input file name attribute (mine is create...[] because my form class name is create, if your is createType it will be createType...[])
3. init $files as an array.

Copy/paste your code here.
