I got stuck how to make my code work, I am trying to upload file using javascript to my python code.
here my HTML
<div class="form-group">
<label for="upload_list" class="control-label">Upload List</label>
<input name="upload_list" id="upload_list" type="file" class="form-control" multiple="true" />
</div>
<a id="make_order" role="button" class="btn btn-primary" href="#">
here my JS that handle the upload.
$("a#make_rfq_order").bind("click", function(ev) {
var customer_upload_list = $('#upload_list').val();
ajax.jsonRpc('/shop/order', 'call', {
'upload_list': customer_upload_list
});
});
and here my python code
def customer_order(self, **post):
if post.get('upload_list'):
.....
if order and order.id:
.....
if post.get('upload_list'):
.....
values.update({
'name': '{0}_{1}'.format('file', upload_list.filename),
})
order.write(values)
return True
if I use 'name': '{0}_{1}'.format('file', upload_list), its work, but only handle the file name,
how to get the actual file submited to my server?...
I'm unable to comment, so I'm answering as best I can, but knowing a bit more about your python server would help (are you using a specific framework or did you code your own python server from scratch, etc...)
I think you're sending the path of the file, not the file itself with this part:
var customer_upload_list = $('#upload_list').val();
Try the below instead:
var file = $('#upload_list').get(0).files[0];
Also, it looks like you're trying to include support for multiple files.
Have you tried building a FormData by iterating over the selected files and adding the FormData to the POST?
Something like this may work, or at least get you in the right direction:
var files = new FormData();
for(var i=0;i< $('#upload_list').val().length;i++){
var file = $('#upload_list').get(0).files[i];
files.append('files[]', file);
}
$.ajax({
url: 'upload.php',
type: 'POST',
data: files
});
the received data will be in list form on the server side, so remember to alter the code to look for a list.
You may have to play around with other paramaters in the POST, like contentType and dataType or processData, but I think the above is sufficient to get a result

I use javascript code to take the file path and paste it into the text input. I am wondering how to make it substitute a predefined server path in front of the file name instead of the path "C:\fakepath", e.g: "\server\dir\data".
$('input[type="file"]').change(function(){
$('input[type="text"]').val( $(this).val());
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form method="post" enctype="multipart/form-data">
<input type="file" onchange="this.form.filename.value = this.value">
<input type="text" name="filename">
</form>
The String object has a number of methods that you could use for this. For example using substr:
<script>
$('input[type="file"]').change(function(){
$('input[type="text"]').val( '\\server\\dir\\data'+$(this).val().substr(11));
})
</script>
Some browsers have a security feature that prevents JavaScript from knowing your file's local full path and because of which you are getting fakepath in the file path url. This security feature is added so that the server won't able to know the filesystem of your machine.
In case you you want to remove the fakepath from path then what you can do is to -
$('input[type="text"]').val( '\'+$(this).val());
This will show the the path as \file_name.extension
of what you wrote i guess that you are trying to do file upload by sending the file data from files object to the server by ajax but you cannot send this path or replace it because it's a random path generated when the server received the file to be uploaded but you can easily use FormData object to send the file to the server then you can handle it from your server
Here's an example
var photo = document.getElementById("photo")
photo.addEventListener("change",function(event) {
var form_data = new FormData();
form_data.append("file",event.target.files[0]);
$.ajax({
url: './phpScripts/up.php',
type: "post",
processData: false,
contentType: false,
data: form_data
}).done(function(e) {
//Code here
})
})
the last point if you wants to get the file path just test the event in the console console.log(event) then search for files object when you can find the file path and access it
I want to be able to upload my file from javascript without using the typical HTML form so that the page doesn't have to refresh when uploading the file to python.
I have not had any success getting my file with request.files.
I have tried two different versions, one using an HTML form and one without.
When trying out the one with the HTML form, the output from request.files is an ImmutableMultiDict that looks like this ImmutableMultiDict([('file', <FileStorage: '^RUT.csv' ('text/csv')>)]) whilst according to my understanding, it is supposed to be a dictionary.
Here is the code:
<form method="POST" action="/get_dims" enctype="multipart/form-data" id="import_form">
<input type="file" name="file" accept=".csv" id="training_set_import" value="import training set"/>
<input type="submit" value="Submit">
</form>
#app.route("/get_dims", methods=["POST"])
def getDatasetDims():
file_n = request.files
print("Got it!")
print(file_n)
return "None"
The other, preferable method I have tried is with javascript using AJAX. When doing this, request.files returns an empty ImmutableMultiDict that looks like this ImmutableMultiDict([]). Here is my code for this:
$(function(){
$("#training_set_import").change(function(){
var file_name = $("#training_set_import").val();
var form = $("#training_set_import").form;
var data = new FormData(form);
if (file_name !== ""){
$.ajax({
type: "POST",
url:"/get_dims",
enctype: "multipart/form-data",
data: {"file": data},
cache: false,
processData: false,
contentType: false
});
}
});
});
The python code is the same.
So my question is, how can I implement the javascript version of this so that I can manupulate the uploaded csv in python ?
Okay i found a thread on here that solved my issues. Here it is: How to upload a file using an ajax call in flask
Hope this helps anyone with the same issue as me !
Summary
I am trying to set my FormData properly using javascript.
I need to be able to upload jpg/png, but I might need to upload some other file types pdf/csv in the future using fetch.
Expected
I expect it to append the data to the form
Error
Working
This snippet is working fine:
const formData = new FormData(document.querySelector('form'));
formData.append("extraField", "This is some extra data, testing");
return fetch('http://localhost:8080/api/upload/multi', {
method: 'POST',
body: formData,
});
Not working
const formData = new FormData();
const input = document.querySelector('input[type="file"]');
formData.append('files', input.files);
Question
Does fetch support multiple file upload natively?
If you want multiples file, you can use this
var input = document.querySelector('input[type="file"]')
var data = new FormData()
for (const file of input.files) {
data.append('files',file,file.name)
}
fetch('http://localhost:8080/api/upload/multi', {
method: 'POST',
body: data
})
The issue with your code is in the lineformData.append('files', input.files);
Instead of that, you should upload each file running a loop with unique keys, like this
const fileList = document.querySelector('input[type="file"]').files;
for(var i=0;i<fileList.length;i++) {
formData.append('file'+i, fileList.item(i));
}
I have created a simple error fiddle here with your code. You can check its' submitted post data here, where you can see that no file has been uploaded.
At the bottom of the page you can find
.
I have corrected the fiddle here with the fix. You can check its'post data from the server, where it shows the details of the two files that I uploaded.
I mentioned this on a similar question: I had the same problem, but with a PHP backend. The unique formData keys work, but I found that the classic HTML notation worked just fine and simply results in an array on the server.
formData.append('file[]', data[i]);
I like that a lot better, since I can use the same methods to process this as with a classic <input type="file" multiple />.
Hey OrientDB Community.
I'm attempting to upload an image into my DB via HTTP API. In my super basic web-page, I select a file and click upload. Simple. Once the button is clicked, I have javascript handling it with jquery and ajax.
Context: This is an educational tool which will have student profiles with their pictures. These images won't be too big (10MB - 20MB-ish).
Here is the HTML upload form:
<h2 class="heading-blue">Upload Image</h2>
<form enctype="multipart/form-data">
<input name="file" type="file" />
<input id="upload_image" type="button" value="Upload" />
</form>
Here is the javascript code:
$('#upload_image').on('click',function(){
console.log("UPLOADING IMAGE");
var formData = new FormData($('form')[0]);
$.ajax
({
type: "POST",
url: "http://localhost:2480/uploadSingleFile/DemoPlayground",
data: formData,
??
??
success: function (){
alert('SUCCESS!');
}
});
});
I'm not sure what to use where it says "/uploadSingleFile/" in the ajax URL parameter. Also, I'm not sure what else needs to be included in the ajax call. (Hence the "??"'s up above).
Some possibilities that I've been reading about:
Call a server-side function and pass the binary data (the image) to the function for it to handle the rest. If this is a good idea, I'm not sure how to do it...so help would be appreciated.
I've read in a couple places that Orient uses Jetty to perform this action. Any pointers on that?
I've got other types of HTTP API to OrientDB requests working, but this one is troublesome and I can't figure it out on my own.
I'm open to looking at this from new angles. Please help! :) THANKS!
I'm trying to give users the possibility to import data from a file that is located on their computer by using jQuery EasyUI form widget:
<form id="my_form" method="POST">
<input type="file" name="my_file" id="my_file" />
</form>
var file_name = $('#my_file').val();
if(file_name)
{
$('#my_form').form('submit', {
url: [url_to_call],
onSubmit: function(param){
param.file_path = file_name;
}
});
}
Then when the user browse on his/her computer for the file, I wanna send the path to a jQuery ajax query to perform some upload action. The problem I have is that filename returns something like this:
C:\fakepath\[name_of_file]
Because of the fakepath string, I am not getting the real path to where the file is located on the user's computer. Does anybody know how I can fix this issue please?
Thank you
Tried this plugin http://malsup.com/jquery/form/#getting-started
this plugin provide a method called AjaxSubmit() which work fine for upload the image. I have used it in 2011.
it's have some issue in IE (old version like 6,7). You need to write some hacks. on the backend Firefox and IE upload the correct file-stream format like Data/Image but in Chrome (Webkit) you will got Octet Stream. You need to parse the file format on server to check that file is not wrong.
I have no idea what your form() function does, as no such method exists in jQuery, but the usual way of uploading a file to the server would be something like this :
$('#my_file').on('change', function() {
$.ajax({
url : [url_to_call],
data : new FormData($('#my_form').get(0)),
processData: false,
contenttype: false
}).done(function(param) {
param.file_path = file_name;
});
});
