Upload file button

Hi there,
What is the best way for me to add an "upload file" button to my Muse and BC e-commerce shop? I am selling personalised products where I want the user to be able to upload a photo.
Do I need a custom web app? If so are there any which already exist?
Or am I better off using a secondary provider and adding the HTML code to my muse site?
Thanks a lot,
Leo

After choosing a jpg for upload, the "Upload File" button on the organization's receiving site of does not respond. The second problem: it's impossible to highlight more that one file at a time.

Clicking the first file, holding down shift and clicking the last file doesn't work. I've tried all manner of command, control, shift combos without success. This one-at-a-time attachment problem also happens in web mail. Are these two issues related? Thanks for non-techie solutions for both issues. I have Safari 5.0.6 (5533.22.3) and Leopard.

Thanks for your response. I do have javascript turned on (not java). To answer your question,
I was trying to upload 3 jpgs to the submissions page of a visual arts website. I could only highlight one jpg at a time in the "Choose File" option, and then the "Upload File" button of the submissions page would not respond.
It's an ongoing problem with this site (I'm the only one with this issue and there are a lot of submissions). I have to send the images as email attachements to the administrator of the site. When doing this via webmail, I still the one attachment at a time problem, but the images get to the administrator. Thanks for helping.

Can only choose attachments one at a time for webmail and for entries to an art organization website. And the site's "Upload File" button will not respond, so I can't even upload the one jpg I have chosen.

I am the only one who can't upload to the submissions page. Javascript is turned on, not java, with Safari 5.0.6 and Leopard. Thanks for helping.

Help adding an "upload file" button to an interactive form in ID CS6

Hello, I would like to add a button for users to upload a file to the interactive form I am creating in InDesign CS6. I would like those filling out the form to be able to click a button that opens their finder/windows and then gives them the option to search through and find a file of their chosing. Ex: I want users to upload their logo, in file formats of .jpg, .eps, .pdf,.ai, .psd, .ind, ect.
Appreciate the help

Salah is talking about something different than you're using.
PDF created with InDesign and Acrobat Pro isn't capable of supporting uploading images into a form.
Salah may be correct, but he's talking about a different product—LiveCycle Designer. Before Acrobat Pro XI, LifeCycle Designer was included with Acrobat Pro—but ONLY for Windows, not for the Mac. It created what's sometimes called XML PDF.
However, it's now a separate product (not included with Acrobat XI), it's still not supported on a Mac, and it doesn't work when viewed on mobile PDF readers like Reader for iOS.

Upload file box off screen

I've recently had trouble with my macbook while uploading files. I click on the "upload file" button and the box that pops up that lets me choose a file is so large that the bottom is off the screen. This means that I can't click on "upload" or "cancel". The only way I know how to proceed is to click on a file and push the enter key. Does anyone know how to make that box smaller so that it fits completely on the screen?

HI,
Go to System Preferences/Displays. Check your resolution.
Also, try Facebook's Simple Loader.
Hard to see in this pic but under where you see "Cancel" click where you see:
"Try the Simple Uploader" ... much easier to use.

Upload File option nolonger in sp2010 form after editing template using infopath

Hi, I want my users of the sharepoint 2010 list to be able to upload a number of documents to list items when required.
We have 2 fields on the form, one so that a document with questions can be added, and one for a similar answer document.
Befor using infopath, the enhanced type text allowed the user to upload a file to that column. But the tab which has the upload option is now missing from the form once edited by infopath.
i don't want the users to have to upload documents elswhere on the sharepoint site and it makes the process much longer.
Also I don't seem to have the attach control on my infopath settings

Hi,
I understand that you want to upload file to SharePoint list using InfoPath form. I can reproduce you issue, after customizing the form in InfoPath, the Upload File button is missing for the rich text box. You can use the attachment control in the InfoPath
form. Since you cannot find the Attachment control in InfoPath, you can check the list settings>Advanced Settings, enable Attachments. Then customize the form in InfoPath again.
Thanks,

File Upload/Download buttons in Table UI

Dear Experts,
I want to give file upload and download buttons in the columns of the Table UI element. I'm not able to achieve upload file with browse functionality on the click and Download file with ws_execute functionality.
If anybody can throw some light, it would be of great help.
I'm sort of a intermediate level developer in WD for ABAP.
Regds,
Aryan.

Hi Aryan,
In order to get the download functionality. Create an button in the Table toolbar and put the below coding into it. You need to basically do the following tasks:
1) First read the table's data into an internal table.
2) Convert the internal table data to STRING format.
3) Now convert it into tab delimited format.
4) Convert this STRING format to XSTRING format
5) Make use of the attach_file_to_response method.
Regards,
Uday

How to "Add" Button to upload file in Notification PG?

I have a question on Extending/Customizing notfn to have "Add" attachment button to upload a document (some stnd template that Our business has) on either NotifDetailsPG or /oracle/apps/fnd/wf/worklist/webui/MoreInfoPG when a Approver opens notification to APPROVE/Reject
I'm wondering why Oracle didn't provide this feature of Uploading a file (along with Response input text area that they provided already) in NotifDetailsPG?
Business Reason: Our Business wants to upload a doc when an approver Rejects the notification (our case: iExpense module filing Exp Report) telling employee to follow some protocals
Question on OAF:
Is it possible to extend NotifDetailsPG or MoreInfoPG to upload a file. So, that when it goes to requestor they can open this file back and read thru. I know we need to insert a record in fnd_documents and fnd_attached_documents and /or fnd_lobs...but i don't know how to retrieve it back....Any hints....
Thanks
Raghu Kulkarni

to clarify again....
In the WF notification during the time of "Reject"ion or "Approv"al, we want to upload a file and then perform Reject/Approve action. Can we extend the page to have Add button to upload file? Is that a lot of work?
Please any one give some suggestions...Thanks

Why does my pop up window appear behind my browser window when I click my "upload a file" button in my applicaiton?

This is a revenue impacting issue for out application. If customers are full screen they think our application's Upload your file" button is broken so we are being over run with support escalations for this issue.
Is there a setting that we can advise them to change?
Thanks a lot;

THERE IS NO SEND BUTTON APPEARING - ONLY A CANCEL BUTTON AFTER I'VE UPLOADED FILES. WHAT GIVES???

I have followed all of the instructions repeatedly and there is no SEND button that appears on the screen where i've entered the email address and subject and where the uploaded files appear.
This is the basic thing one needs, is a SEND button so one can use AdobeSEND
Very disappointed.

Are you running AdBlock (or something like that) on the browser that you’re not seeing the Send button on? That might explain it, especially if you have opted to Disable Social Media Buttons.
If you do a web search for "adblock share-button" you will see a number of postings about this issue with buttons missing from other sites.

Request.getParameter() when uploading files

Hi, I need to upload files and do other works .. such that, in my html ..
<form name="composer" method="post" ENCTYPE="multipart/form-data">
<input type=hidden name="a" value="a">
<input type=File name=inputfile>
<inpu type=button name=Upload onClick='upload file'>
<inpu type=button name=otherStuff onClick='do other stuff'>
</form>
In the jsp for 'do other stuff', I have the following statement to get the value of a
String a = request.getParameter("a");
However, it returns 'null', if I erase the 'ENCTYPE' part from the html file, it works. How can I get it right?

If your ENCTYPE is multi-part/form-data, then there is another technichque to read the form parameters.
request.getParameter() won't work.
first u need to read the requenct explicitely and divide the contents into parameters, files etc. and then read the parameter values.
you can get a lot of stuff regarding this on web, like 'uploading files using jsp'.
have fun!!

How to upload file from client to server

Can someone please help.
User needs to browse file on his desktop and upload file using browse button. This file should then be uploaded to the server. I am using javascript in the front end and servlet in the back.
Any help will be highly appreciated.
Thanks,
Indrasish

Jakarta Commons FileUpload is the standard way of doing the file uploading these days. You can find source, binaries and documentation at the Jakarta Site http://jakarta.apache.org/ . The Commons has a number of subprojects, so start with the Commons libraries, then find FileUpload.

Hello i had exactly the same error, but not with file upload.
I'm sure you have in your application lib directory to jars which aren't compatible to each other.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.
bye
