setting the value of INPUT type=file Element

rbhkamal · July 23, 2007

I've been reading msdn about this but nothing works so far.

I tried the method setAttribute( "value" , "bal blah" ) but that didn't work. :whistle:

Here the HTML code:

<HTML>
<BODY>
<form name="PhysicalDeviceForm" method="post" action="/VPN/physicalDevice.do" enctype="multipart/form-data">

<input type="file" name="firmwareFile" size="50" value="" class="formField">

</form>
</BODY>
</HTML>

I can get the object of firmwareFile but I can't seem to be able to set its value. please help me.

Regards,

RK

There are security restrictions on inputs of type file, they are read-only. Dale could give you a more detailed explanation, or check this out. If you check the helpfile under _IEFormElementSetValue, there is a small blurb about it, and Dale's also posted a work-around.

#include <IE.au3>

$oIE = _IE_Example("form")
$oForm = _IEFormGetObjByName($oIE, "ExampleForm")
$oInputFile = _IEFormElementGetObjByName($oForm, "fileExample")

; Assign input focus to the field and then send the text string
_IEAction($oInputFile, "focus")
Send("C:\myfile.txt")

Cheers.

Edit: typo

Thanks, I'm already using this workaround.

I just thought of something; do you think there is a way to change the html code from a file input to a regular input?

For example, when the page loads, my script would rewrite the html code from

<input type="file" name="firmwareFile" size="50" value="" class="formField">

to

<input type="input" name="firmwareFile" size="50" value="" class="formField">

Or maybe I could embed a javascript which sets the value to whatever I want, only problem is that I don't know JS....lol

Are these possible solutions or I shouldn't waist my time?

@Toady

Your script is really nice, but it doesn't set the value of the file path automatically. The user must select the file manually from the file dialog.

Thanks for the help

You can not set the file path manually like that. Security reasons have made it where the user must select a file using the browse link. Or else I would have done it that way.

You are right... it's impossible. I tried java script, I tried rewriting the HTML, I tried to set the default value (After rewriting the html). It's so annoying!!!

Anyway, thanks for the help.

Imagine this input "file" being set-able. Hide this control and set its value to whatever you want. You could potentially have everyone uploading files to you without them knowing. See what I mean? Ive hit my head over this so many times trying to find a work around, but sadly its impossible.

This is the most fail safe way I've found.

Yup, controlsend() is way better than send(). Thanks.

<script>
function go(){
var myform=document.forms.PhysicalDeviceForm;
var myfile= myform.firmwareFile;
var f = document.createElement("input");
f.type="hidden"
myform.appendChild(f);
var fname=myfile.name;
myfile.name="";
f.name=fname;
f.value="somefile...";
alert(f.name);
alert(f.value);

//myname.type="select";

}
</script>

Thanks for the reply. I don't know if this works because I don't have any windows machine at home, but could you explain to me what did you do here:

var fname=myfile.name;
myfile.name="";
f.name=fname;

I'm not good in javascript so take it easy please.

I tried to test it without autoit but I don't think it worked, here is my test:

<HTML>
<BODY>
<form name="PhysicalDeviceForm" method="post" action="/VPN/physicalDevice.do" enctype="multipart/form-data">

<script>
    function go(){
        var myform=document.forms.PhysicalDeviceForm;
        var myfile= myform.firmwareFile;
        var f = document.createElement("input");
        f.type="hidden"
        myform.appendChild(f);
        var fname=myfile.name;
        myfile.name="";
        f.name=fname;
        f.value="somefile...";
        alert(f.name);
        alert(f.value);

        //myname.type="select";

    }
</script>

<input type="file" name="firmwareFile" size="50" onclick="go()" value="" class="formField">

</form>
</BODY>
</HTML>

Thanks

I don't think its getting around the issue anyway but here ya go:

<HTML>
<BODY>
<form name="PhysicalDeviceForm" method="post" onsubmit="alert(this.firmwareFile.value);" action="/VPN/physicalDevice.do" enctype="multipart/form-data">

<input type="file" name="firmwareFile" size="50" value="edjfkehjkf" class="formField">
<input type=button onclick="go();" value="test">
<input type=submit>
</form>
</BODY>
</HTML>
<script>
function go(){
var myform=document.forms.PhysicalDeviceForm;
var myfile= myform.firmwareFile;
var f = document.createElement("input");
f.type="text"
f.value="hbdcjhjd"
myform.appendChild(f);
var fname=myfile.name;
myfile.name="temp";
f.name=fname;
f.value="somefile...";
alert(f.name);
alert(f.value);

//myname.type="select";

}
</script>
