<input type="file" id="file-id" name="file_name" onchange="theimage();">
This is my upload button.
<input type="text" name="file_path" id="file-path">
This is the text field where I have to show the full path of the file.
function theimage(){
var filename = document.getElementById('file-id').value;
document.getElementById('file-path').value = filename;
alert(filename);
}
This is the JavaScript which solve my problem. But in the alert value gives me
C:\fakepath\test.csv
and Mozilla gives me:
test.csv
But I want the local fully qualified file path. How to resolve this issue?
If this is due to browser security issue then what should be the alternate way to do this?
Some browsers have a security feature that prevents JavaScript from knowing your file's local full path. It makes sense - as a client, you don't want the server to know your local machine's filesystem. It would be nice if all browsers did this.
Use
document.getElementById("file-id").files[0].name;
instead of
document.getElementById('file-id').value
I use the object FileReader on the input onchange event for your input file type! This example uses the readAsDataURL function and for that reason you should have an tag. The FileReader object also has readAsBinaryString to get the binary data, which can later be used to create the same file on your server
Example:
var input = document.getElementById("inputFile");
var fReader = new FileReader();
fReader.readAsDataURL(input.files[0]);
fReader.onloadend = function(event){
var img = document.getElementById("yourImgTag");
img.src = event.target.result;
}
If you go to Internet Explorer, Tools, Internet Option, Security, Custom, find the "Include local directory path When uploading files to a server" (it is quite a ways down) and click on "Enable" . This will work
I am happy that browsers care to save us from intrusive scripts and the like. I am not happy with IE putting something into the browser that makes a simple style-fix look like a hack-attack!
I've used a < span > to represent the file-input so that I could apply appropriate styling to the < div > instead of the < input > (once again, because of IE). Now due to this IE want's to show the User a path with a value that's just guaranteed to put them on guard and in the very least apprehensive (if not totally scare them off?!)... MORE IE-CRAP!
Anyhow, thanks to to those who posted the explanation here: IE Browser Security: Appending "fakepath" to file path in input[type="file"], I've put together a minor fixer-upper...
The code below does two things - it fixes a lte IE8 bug where the onChange event doesn't fire until the upload field's onBlur and it updates an element with a cleaned filepath that won't scare the User.
// self-calling lambda to for jQuery shorthand "$" namespace
(function($){
// document onReady wrapper
$().ready(function(){
// check for the nefarious IE
if($.browser.msie) {
// capture the file input fields
var fileInput = $('input[type="file"]');
// add presentational <span> tags "underneath" all file input fields for styling
fileInput.after(
$(document.createElement('span')).addClass('file-underlay')
);
// bind onClick to get the file-path and update the style <div>
fileInput.click(function(){
// need to capture $(this) because setTimeout() is on the
// Window keyword 'this' changes context in it
var fileContext = $(this);
// capture the timer as well as set setTimeout()
// we use setTimeout() because IE pauses timers when a file dialog opens
// in this manner we give ourselves a "pseudo-onChange" handler
var ieBugTimeout = setTimeout(function(){
// set vars
var filePath = fileContext.val(),
fileUnderlay = fileContext.siblings('.file-underlay');
// check for IE's lovely security speil
if(filePath.match(/fakepath/)) {
// update the file-path text using case-insensitive regex
filePath = filePath.replace(/C:\\fakepath\\/i, '');
}
// update the text in the file-underlay <span>
fileUnderlay.text(filePath);
// clear the timer var
clearTimeout(ieBugTimeout);
}, 10);
});
}
});
})(jQuery);
On Chrome/Chromium based apps like electron you can just use the target.files:
(I'm using React JS on this example)
const onChange = (event) => {
const value = event.target.value;
// this will return C:\fakepath\somefile.ext
console.log(value);
const files = event.target.files;
//this will return an ARRAY of File object
console.log(files);
}
return (
<input type="file" onChange={onChange} />
)
The File object I'm talking above looks like this:
{
fullName: "C:\Users\myname\Downloads\somefile.ext"
lastModified: 1593086858659
lastModifiedDate: (the date)
name: "somefile.ext"
size: 10235546
type: ""
webkitRelativePath: ""
}
So then you can just get the fullName if you wanna get the path.
Note that this would only work on chrome/chromium browsers, so if you don't have to support other browsers (like if you're building an electron project) you can use this.
I came accross the same problem. In IE8 it could be worked-around by creating a hidden input after the file input control. The fill this with the value of it's previous sibling. In IE9 this has been fixed aswell.
My reason in wanting to get to know the full path was to create an javascript image preview before uploading. Now I have to upload the file to create a preview of the selected image.
If you really need to send the full path of the uploded file, then you'd probably have to use something like a signed java applet as there isn't any way to get this information if the browser doesn't send it.
Use file readers:
$(document).ready(function() {
$("#input-file").change(function() {
var length = this.files.length;
if (!length) {
return false;
}
useImage(this);
});
});
// Creating the function
function useImage(img) {
var file = img.files[0];
var imagefile = file.type;
var match = ["image/jpeg", "image/png", "image/jpg"];
if (!((imagefile == match[0]) || (imagefile == match[1]) || (imagefile == match[2]))) {
alert("Invalid File Extension");
} else {
var reader = new FileReader();
reader.onload = imageIsLoaded;
reader.readAsDataURL(img.files[0]);
}
function imageIsLoaded(e) {
$('div.withBckImage').css({ 'background-image': "url(" + e.target.result + ")" });
}
}
seems you can't find the full path in you localhost by js, but you can hide the fakepath to just show the file name. Use jQuery to get the file input's selected filename without the path
The best solution for this, I've found, is to use a middleware like Multer. Here's a quick rundown:
npm i multer
Add enctype="multipart/form-data" to your html form.
In your backend dock where you're making your post request, require multer (const multer = require('multer'))
In the same dock, set your upload destination: const upload = multer({dest:'uploas/'}). This will automatically create a local folder called 'uploads' where your files will be added. The code I've included shows you how to upload to your local disk storage. If you're using cloud storage (e.g. AWS, Azure, Cloudinary etc.) you can check out the Multer docs to see how to manage that. There aren't too many extra steps though.
in your post request, add 'upload.single' (for one file) or 'upload.array' (for multiple files), like this:
router.post('/new', upload.single('image'), async function(req, res) { //'image' should be the name of the input you're sending in the req.body
console.log(req.file) //note, if you're using 'upload.array', this should be 'req.files'
});
the req.file will have a full path name that you can use in your post request. For more information, check out the Multer docs:
https://www.npmjs.com/package/multer
I hope this helps!
You would be able to get at least temporary created copy of the file path on your machine. The only condition here is your input element should be within a form
What you have to do else is putting in the form an attribute enctype, e.g.:
<form id="formid" enctype="multipart/form-data" method="post" action="{{url('/add_a_note' )}}">...</form>
you can find the path string at the bottom.
It opens stream to file and then deletes it.
Hy there , in my case i am using asp.net development environment, so i was want to upload those data in asynchronus ajax request , in [webMethod] you can not catch the file uploader since it is not static element ,
so i had to make a turnover for such solution by fixing the path , than convert the wanted image into bytes to save it in DB .
Here is my javascript function ,
hope it helps you:
function FixPath(Path)
{
var HiddenPath = Path.toString();
alert(HiddenPath.indexOf("FakePath"));
if (HiddenPath.indexOf("FakePath") > 1)
{
var UnwantedLength = HiddenPath.indexOf("FakePath") + 7;
MainStringLength = HiddenPath.length - UnwantedLength;
var thisArray =[];
var i = 0;
var FinalString= "";
while (i < MainStringLength)
{
thisArray[i] = HiddenPath[UnwantedLength + i + 1];
i++;
}
var j = 0;
while (j < MainStringLength-1)
{
if (thisArray[j] != ",")
{
FinalString += thisArray[j];
}
j++;
}
FinalString = "~" + FinalString;
alert(FinalString);
return FinalString;
}
else
{
return HiddenPath;
}
}
here only for testing :
$(document).ready(function () {
FixPath("hakounaMatata:/7ekmaTa3mahaLaziz/FakePath/EnsaLmadiLiYghiz");
});
// this will give you : ~/EnsaLmadiLiYghiz
I have some javascript code that allows users to drag and drop files in IE.
The problem I have is that they would like the file deleted after being dragged, but I can't seem to get the file path, just the name.
I have seen many references to e.dataTransfer.files[0].path, but it always comes back as 'undefined' when I try it.
Any ideas why e.dataTransfer.files[0].path does not work, or how I can get the file path?
$(document).ready(function (ex) {
var holder = document.getElementById('holder');
holder.ondragover = function () { this.className = 'hover'; return false; };
holder.ondrop = function (e) {
e.preventDefault();
var file = e.dataTransfer.files[0];
var path = e.dataTransfer.files[0].path;
fileArray.push(file);
//alert(e.target.id);
var reader = new FileReader();
reader.readAsDataURL(file);
};
});
that's not possible for a web app, but if your users would run an app on their machine, you could build an electron app. inside electron you get the e.dataTransfer.files[0].path property, which you can then use to delete the file.
https://www.electronjs.org/
The file doesn't have property path.
You can experiment with it here and the complete list of file properties can be found here.
To read the file one uses FileReader as you did, without using the path explicitly.
After trying everything I could find, I am of the opinion that it is not possible.
<input type="file" id="file-id" name="file_name" onchange="theimage();">
This is my upload button.
<input type="text" name="file_path" id="file-path">
This is the text field where I have to show the full path of the file.
function theimage(){
var filename = document.getElementById('file-id').value;
document.getElementById('file-path').value = filename;
alert(filename);
}

here only for testing :
$(document).ready(function () {

});
// this will give you : ~/EnsaLmadiLiYghiz
I am using plupload to let users upload images. But I also want to generate thumbnails for preview before they finally decide to keep it. I understand currently "Image preview" feature is not present in plupload. So to work around this I decided to submit a new form containing just one file for each image added, & let the server process it & return a thumbnail.
Now my question is how do I get the handle on the file object from the plupload so that I can create an "input" file field dynamically.
Currently I iterate over uploader.files & set input.name but I dont know how to set the input.value field, since I cant seem to get the complete file path of the file added.
I am up for any suggestions (in addition to replacing this approach completely), I just need thumbnail of the file selected for upload.
Maybe my answer is a bit late, but I searched today for a similar solution and came up with the following approach. It will only work with the HTML5 Runtime.
As there is no way to get the file objects from plupload, I changed the onchange event of the dynamically created input field and store the file objects for myself. This is done by binding to the PostInit-Event.
After that I can show the image to the user by using the FileReader API introduced with HTML 5. So there is no need to send the image to the server. See my FilesAdded Listener below.
// Currently added File Objects
var nativeFiles = {};
var uploader = new plupload.Uploader({
runtimes : 'html5,html4',
// Your settings...
});
uploader.bind('PostInit', function(up, params) {
// Initialize Preview.
if(uploader.runtime == "html5") {
var inputFile = document.getElementById(uploader.id + '_html5');
var oldFunction = inputFile.onchange;
inputFile.onchange = function() {
nativeFiles = this.files;
oldFunction.call(inputFile);
}
}
});
uploader.bind('FilesAdded', function(up, files) {
for (var i in files) {
// Your code...
// Load Preview
if(uploader.runtime == "html5") {
var fileObject = uploader.getFile(files[i].id);
var reader = new FileReader();
reader.onload = (function(file, id) {
return function(e) {
var span = document.getElementById('thumb_'+id);
span.innerHTML = "<img src='"+e.target.result+"'/>";
};
})(nativeFiles[i], files[i].id);
reader.readAsDataURL(nativeFiles[i]);
}
}
});
