How to make that input type='file' will show the file that was added previously? So when admin open post page and want to make some changes he doesn't have to add file twice, i tried few things but input is always empty? It is possible to do it? That input will show file that was added previously? I mean the name of the file or path?
I dont think that is even possible because of security reasons.

i have not tried anything as i am unsure where to start.
I'm pretty sure you want to get the full file path of a file uploaded via an HTML input element, if not, let me know.
If so, such behavior is intentionally blocked by most browsers, except for firefox. See How to get full path of selected file on change of <input type=‘file’> using javascript, jquery-ajax?. If you want to raed the file, you can use the FileReader class. Alternatively, you can make an object URL to the file object, on the onchange event, simply
var url = URL.createObjectURL(event.target.files[0]);
to use for reading purposes.
I have problem with my code where i want to know selected file in file chooser, i try with system.print.ln can respon selected file but with text take result null.
Where error happen?
If you want someone to look at your issue quickly, DONT put your code as screenshot. Anyway I think your issue is at declaring actionStatus field using #FXML. Remove the "static" keyword.
I have a VBScript that goes over an HTML form, fills it with fixed values and then submit it. It works fine so far, but now i need to set the location of a file that is going to be uploaded within the form data.
I believed if I set the location on the value it was going to work, but it doesn't.
<input type='file' name="file_field" value='file_location'/>
Also, I found this while researching. It says...
input type=file
Value: Sets or retrieves the displayed value for the control object. This value is returned to the server when the control object is submitted.
Is there a way (by code) to fill that input, even with jQuery?
No. This is not possible.
Browsers block against setting the value attribute on input of file type for security reasons so that you can't upload a file without the user's selected any file himself.
I have an HTML form with a text input named "name", file upload input named "myFile" (shows Browse button), and a submit button (named "Upload").
I accidentally pressed enter before I choose a file, and a file with 0 length was uploaded to the servlet. How to make sure the browser doesn't post if the file is not selected, or the file name is empty... Thanks!
David, your comment is correct. The answer is to use javascript to check whether the text input is filled with info if manual input is required. I also could use the javascript to put the file name without the path to fill in the form automatically.
How do you preset the filepath in a input type=file?
I want the field to already have a path in it -> Read-Only possibly?
You can not preset the input[type=file] element.
The only reliable thing you can do is read back the filename with the value property on the DOM. Some browsers prepend a fake path, e.g. C:\fakepath\some-file.jpg.
You can't do that, it's a security issue. Doing so would let a web site operator create a form with a hidden file field, with a path filled in, so that when the user submits the form the browser would also upload a file of the website operator's choosing.
