Upload directory

FelipeTv · September 20, 2010, 10:16pm

Hi,
The documents are not uploaded in a particular directory. I send variables through the place where you will upload.
And there is no example in the documentation that shows this.
The component is limited or is it possible?

Fedor · September 21, 2010, 8:57am

It is very easy to do. Server script has a variable with upload target. Set it to whatever you need.

FelipeTv · September 21, 2010, 12:33pm

The question that can not silence: How?
The script I use is the usual in .Net:

dhtmlXVaultObject vault = new (); vault.setImagePath ("codebase / imgs /"); vault.setServerHandlers (UploadHandler.ashx" "GetInfoHandler.ashx" "GetIdHandler.ashx");

        vault.setFilesLimit (1);

        vault.create (vaultDiv ");

</ Script>

Where does this variable?

Fedor · September 21, 2010, 12:41pm

Man, as I told, it’s on server! Look into “UploadHandler.ashx”

    private const string UploadFolder = @"c:\upload\";

FelipeTv · September 21, 2010, 1:11pm

Fedor, thanks for the prompt service.
I’ve seen this code in the file.
But how to redeem this parameter using the “UPLOAD”?
Perhaps expressed myself bad. I use ASP to interface with server side. Net.

<%
filelocation var = request.querystring ("upfileon)
'This is my variable and this is the asp script
%>
<script>
dhtmlXVaultObject vault = new ();
vault.setImagePath ("codebase / imgs /");
vault.setServerHandlers (UploadHandler.ashx "
"GetInfoHandler.ashx"
"GetIdHandler.ashx");

vault.setFilesLimit (1);

vault.create (vaultDiv ");
</ Script>

Would you show me?

Fedor · September 21, 2010, 1:24pm

Sorry, this is wrong. This page is not ASP script, it is simply a html view. If you want to change the location, please go to the server side script. I do not understand what you are trying to do?

FelipeTv · September 21, 2010, 1:54pm

No problem Fedor, try follow me.
My code:

<html>
<head>
    <title>Upload Control</title>
    <link rel="stylesheet" type="text/css" href="codebase/dhtmlxvault.css" />
    <script language="JavaScript" type="text/javascript" src="codebase/dhtmlxvault.js"></script>
    <script language="JavaScript" type="text/javascript">
        var vault = null;
        function doOnLoad() {
            vault = new dhtmlXVaultObject();
            vault.setImagePath("codebase/imgs/");
            vault.setServerHandlers("UploadHandler.ashx", "GetInfoHandler.ashx", "GetIdHandler.ashx");
            vault.create("vault");
	}
    </script>
</head>
<body onLoad="doOnLoad()">
path:<input type="text" value="" size="25"><br>&nbsp;
<div id="vault"></div>
</body>
</html>

My screen:

I want upload the file teste.txt to directory showed no input text and not in @"c:\upload";
With this, I can always choose where to save the file.

could understand me?

Fedor · September 21, 2010, 2:34pm

Yes. Here is the sample.

html code for the new field:

<p>Path: <input id="save_path_txt" value="c:\upload\"><input type="button" value="Set path" onclick="vault.setFormField('save_path',document.getElementById('save_path_txt').value)"></p>

server code in “UploadHandler.ashx”:

finally
{
    fp.Dispose();
    fp.CloseStreams();
    CurrentSize = "-1";
}

try {
    string original_file = UploadFolder + fp.CurrentFileName;
    string destination_file = context.Request.Params["save_path"] + fp.CurrentFileName;
    File.Move(original_file, destination_file);
}
catch (Exception ex)
{
    // process this error
}

Tks a lot but don´t work.

Original code:
http://ww1.dlbca.com.br/vaultx/index.html

Your code:
http://ww1.dlbca.com.br/vaultx/Upload%20Target.html
save file with filename.ext

Destination File:
http://ww1.dlbca.com.br/vaultx/files/

Fedor · September 21, 2010, 3:43pm

There is a missing { in server handler - after the word “try”

Linha 123:                  try {
Linha 124:                      string original_file = UploadFolder + fp.CurrentFileName;
Linha 125:                      string destination_file = context.Request.Params[&quot;save_path&quot;] + fp.CurrentFileName;
Linha 126:                      File.Move(original_file, destination_file);
Linha 127:                  }

FelipeTv · September 21, 2010, 4:02pm

Almost there Fedor.
Now is working but it just saves the file in the original directory.
It doesn’t move to the directory indicated in the text field.

Original Destination File:
http://ww1.dlbca.com.br/vaultx/files/

Directory indicated in the text field:
http://ww1.dlbca.com.br/vaultx/files2/

Fedor · September 21, 2010, 4:04pm

Man, do you have some debugger experience at all? Or do you think I have no other things to do? Give me your link again.

FelipeTv · September 21, 2010, 4:14pm

It says it cannot find the vault variable from the event handler

onClick="vault.setFormField

Try to move your script code up to the page header.

    <script language="JavaScript" type="text/javascript">
        var vault = null;
            vault = new dhtmlXVaultObject();
            vault.setImagePath("codebase/imgs/");
            vault.setServerHandlers("UploadHandler_move.ashx", "GetInfoHandler.ashx", "GetIdHandler.ashx");
            vault.create("vault1");
    </script>

and do the code like we said in the document load handler.

<html>
<head>
    <title>Upload Control</title>
    <link rel="stylesheet" type="text/css" href="codebase/dhtmlxvault.css" />

    <script language="JavaScript" type="text/javascript" src="codebase/dhtmlxvault.js"></script>

    <script language="JavaScript" type="text/javascript">
        var vault = null;
function init_vault() {
            vault = new dhtmlXVaultObject();
            vault.setImagePath("codebase/imgs/");
            vault.setServerHandlers("UploadHandler_move.ashx", "GetInfoHandler.ashx", "GetIdHandler.ashx");
            vault.create("vault1");
}
    </script>

    <style>
	body{font-family:arial;font-size:12px}
	h1 {cursor:pointer;font-size:16px;margin-left:10px;line-height:10px}
	xmp {color:green;font-size:12px;margin:0px;font-family:courier;background-color:#e6e6fa;padding:2px}
	.hdr{
		background-color:lightgrey;
		margin-bottom:10px;
		padding-left:10px;
	}
    </style>

</head>
<body onload="init_vault()">
    <div id="vault1">
    </div>
<p>Path: <input id="save_path_txt" name="save_path_txt" value="E:\Sistemas\UploadVault\dhtmlx\dhtmlxvault_pro 1.6\handlers\aspx\files2\">  <input type="button" value="Set path" onClick="vault.setFormField('save_path',document.getElementById('save_path_txt').value);alert(document.getElementById('save_path_txt').value)"></p>
</body>

</html>

Check if the folder2 is writable by aspnet user, also add some logging for the exception in the file.move code part.

FelipeTv · September 21, 2010, 5:12pm

Fedor,

Not working but now i know how to do.
I’ll check with my network administrator permissions of the folders in IIS.

Tks a million.

ziobello · November 24, 2010, 11:53am

Hi to all.

I’ve the same problem using JSP Handler and doesn’t work.

I want to change dinamically the upload folder using:
vault.setFormField(“upload_folder”, document.getElementById(‘contextCurrentDir’).value);

where contextCurrentDir is my txt field.

I’m debugging UploadHandler.jsp and the problem is getting the POST variable upload_folder
String uploadFolder = request.getParameter(“upload_folder”);

The variable uploadFolder is always null,
then the POST parameter is not passed to UploadHandler.jsp.

Can someone help me ?

Thanks in advance

Saverio

Fedor · December 15, 2010, 2:29pm

Hi, you should do it in a different way. As long as we have our own request processor, you should use the following code:

    if (item.isFormField()) {
        //processFormField
        String fieldName = item.getFieldName();
        String value = item.getString();
        // do your work here
    } else {

Thanks very much.
Now i understand and it works

Hi Fedor, i was looking for something like this

<p>Path: <input id="save_path_txt" value="c:\upload\"><input type="button" value="Set path" onclick="vault.setFormField('save_path',document.getElementById('save_path_txt').value)"></p>

but if my form have 20 fields then i need to press the “Set path (or something)” button for attach the value in every one

I think we need a event called onBeforeUpload to call a handler and make this more flexible

Sorry for my bad english
