Thanks a lot RomnickSusa i always try to make it harder. The easier way is yours, i'm sure. It was successfully. I will edit my question with the new function in controller, you can check it and if you think it can be more efficient just put a comment.

Okay, update your question then ill update my answer. It would be better if you provide your controller's code. Add a comment. The Overflow Blog.

A file input's value attribute contains a DOMString that represents the path to the selected file s. If the user selected multiple files, the value represents the first file in the list of files they selected. The accept attribute value is a string that defines the file types the file input should accept.

This string is a comma-separated list of unique file type specifiers. Because a given file type may be identified in more than one manner, it's useful to provide a thorough set of type specifiers when you need files of a given format. The capture attribute value is a string that specifies which camera to use for capture of image or video data, if the accept attribute indicates that the input should be of one of those types.

If this attribute is missing, the user agent is free to decide on its own what to do. If the requested facing mode isn't available, the user agent may fall back to its preferred default mode. Note: capture was previously a Boolean attribute which, if present, requested that the device's media capture device s such as camera or microphone be used instead of requesting a file input.

When the multiple Boolean attribute is specified, the file input allows the user to select more than one file. In addition to the attributes listed above, the following non-standard attributes are available on some browsers. You should try to avoid using them when possible, since doing so will limit the ability of your code to function in browsers that don't implement them. The Boolean webkitdirectory attribute, if present, indicates that only directories should be available to be selected by the user in the file picker interface.

Though originally implemented only for WebKit-based browsers, webkitdirectory is also usable in Microsoft Edge as well as Firefox 50 and later.

However, even though it has relatively broad support, it is still not standard and should not be used unless you have no alternative. Each unique file type specifier may take one of the following forms:. The accept attribute takes as its value a string containing one or more of these unique file type specifiers, separated by commas.

For example, a file picker that needs content that can be presented as an image, including both standard image formats and PDF files, might look like this:. Note: You can find this example on GitHub too — see the source code , and also see it running live.
