[英]CodeIgniter make file uploads optional
我找到了一些使上传成为可选的示例,但到目前为止,它对我而言并不起作用。 我可能错过了一些东西,所以我希望有人能抓住它? 这是我正在关注的链接
https://blog.smalldo.gs/2013/03/optional-file-upload-field-codeigniter/
到目前为止,如果我不上传文件,但是我可以编辑产品,但是如果上传文件,则提示您未选择要上传的文件。 请帮忙。 谢谢。

您没有告诉上传库从哪个字段获取文件。
$this->upload->do_upload() // <-- no argument for this method provided
如果未提供任何字段名,则默认情况下它将尝试从userfile
字段[docs]中获取文件,但是您的文件输入称为upload
如代码示例所示。 所以你应该做
if(!$this->upload->do_upload("upload")){
另外,请注意,在客户端,带有文件字段的表单应声明为
<form method="post" action="some_action" enctype="multipart/form-data" />
否则文件字段也将为空。
