我正在尝试上传一张图片使用angular和vichUploaderBundle为symfony。
想法如下,
我有一些标签,如果你点击它们,它们会显示不同的表单,其中一个是用于文件上传的。我的问题是,我如何上传图像?我的意思是正确的方式。我有一个html.twig文件,里面有一个表单(我使用的是includes of twig engine)。假设我有这个form.html.twig
<form onsubmit="{{ path('upload-new-file') }}">
<input type="file" id="someFile"/>
<button> Upload Image </button>
</form>一旦你选择了图片,点击Upload,这将决定哪个网址与upload-new-file(routing.yml)匹配(例如,它将执行一些查询来上传文件)
我的主要问题是我被弄糊涂了,因为我一直在用php编程我的表单(使用createForm,form-> is isvalid等),然后用twig呈现它们,我也使用vichUploaderBundle。在我描述的情况下,我无法做到这一点,因为我没有“表单”来呈现它。({{form(form)}})。我没有以通常的方式将表单作为参数传递(就像symfony文档中一样;$this->render(‘omeTemplate.html.twig’,array (' form‘=> $form)
假设我们有一个带有选项卡的网页,如果您单击其中一个选项卡,它将显示某个表单,其中一个表单包含上载输入,您选择一个图像并单击upload,然后呢?回想一下,我使用angularjs、vichuploaderbundle、symfony和Doctrine作为ORM。
提前感谢!

}并添加文件路径,然后删除路径
