File upload problem(firefox works, IE not)

db

Hi@all,

I am always thinking that there is no problems that I can not solve.
But now i changed my idea......

And I have posted it in javascript group, since i think both javascript
and php are involved in this problem, i post it here as well. If that
is "illegal", please delete it, thanks.
My problem is that i use javascript to generate a form, the form
contains a normal file uploader. The code is somehow like this:
var inputform =
document.getElementById('inputform');
if (!inputform) {
inputform =
document.createElement('form');

inputform.setAttribute('enctype','multipart/form-data');

inputform.setAttribute('method','post');
inputform.setAttribute('action',
'programMotes.php');
filetext=document.createTextNode(' Mote
Executable: ');

exefile=document.createElement('input');
exefile.setAttribute('type', 'file');
exefile.setAttribute('name',
'moteProgramFile');
text2=document.createTextNode(' ');

inputButton=document.createElement('input');
inputButton.setAttribute('type',
'submit');
inputButton.setAttribute('value',
'Flash the marked motes');
hidden =
document.createElement('input');
hidden.setAttribute('type', 'hidden');
hidden.setAttribute('name', 'sent');
hidden.setAttribute('value', 'true');
inputform.appendChild(tbl);
inputform.appendChild(filetext);
inputform.appendChild(exefile);
inputform.appendChild(text2);
inputform.appendChild(inputButton);
inputform.appendChild(hidden);
br=document.createElement('br');
br2=document.createElement('br');

finishedText=document.createTextNode('Loaded.');
inputform.insertBefore(br, filetext);
inputform.insertBefore(finishedText,
br);
inputform.insertBefore(br2,
finishedText);
content.appendChild(inputform);
}
And then in corresponding php file moteProgramFile.php:
$target_path = "uploads/";
$target_path = $target_path .
basename($_FILES['moteProgramFile']['name']);
echo $target_path;
if(move_uploaded_file($_FILES['moteProgramFile']['tmp_name'],
$target_path))
{
echo "The file ". basename(
$_FILES['moteProgramFile']['name']).
" has been uploaded";
}
else
{
echo "There was an error uploading the file, please
try again!";
}
With using firefox, there is absolutely no problem, but with using IE,
the file can just not be uploaded! Does someone have an idea?
thanks in advance

TLDR (Too Long, Didn't Read)

Well what is the nature of the error? Have you tried examining the $_FILES
array? var_dump($_FILES). What does $_FILES['moteProgramFile']['error']
show? Does the form not build? Why do you use javascript for building the
form? If you had a similar but static form, would that upload anything in
IE?

For debugging try to leave all the textnodes out, all unnecessary fields,
leave just the form, the file field and submit button to narrow down the
problem. Then describe what appears to be happening once you've selected a
file and hit the submit. Then attatch the output of var_dump($_FILES). Then
there's a remote chance someone could actually manage to help you.

Hi, thanks for replying!

Yes, i have. The $_FILES array is totally empty.
$_FILES['moteProgramFile']['error'] doesnt contain anything either. I
have to use javascript since i am using AJAX to save page loading time.
Actually what i do is using javascript to make a request to a php
function, this php function will provide certain XML stream
dynamically. According to the XML stream, certain table is build. If i
just use static form, IE works without any problem.

Furthermore, i have embedded a hidden field inside the form to check
whether the form is really submitted. And it does......

Now i dont know how to keep on going, please HELP!

thx

Try this, I remembered that setAttribute() should be avoided.

inputform.enctype = 'multipart/form-data';
inputform.method = 'post';

Thank you, but this does not work either......

What about making a div that contains HTML in it?

Example is:
formdiv = document.createElement('div');
formdiv.innerHTML = '<form action=".....">\
Don\'t forget to use backslashes after each line!\
</form>';

Actually I am using div now. In the html part:

<div class="csc-header csc-header-n1" id="dynamiccontent">Loading WSN
status...</div>

and in the javascript part, firstly i get the div with using
var content =
document.getElementById('dynamiccontent');

and then generate form, after that i use
content.appendChild(inputform)

Is that right?

What I meaning was:
var content = document.getElementById('dynamiccontent');
content.innerHTML = ''
+ '<form action="..." method="post" enctype="multipart/form-data">'
+ '<input ..../> or some stuff like that.'
+ '</form>';

That should work, i think. But the problem is the form contains a
dynamic table, if i do like above, i can not append that table to the
form, or?

thanks anyway

You can.

content.innerHTML = ''
+ '<form action="..." method="post" enctype="multipart/form-data">'
+ '<table><tr><td>'
+ 'something and something......'
+ '</td></tr></table>'
+ '</form>';

You can.

content.innerHTML = ''
+ '<form action="..." method="post" enctype="multipart/form-data">'
+ '<table><tr><td>'
+ 'something and something......'
+ '</td></tr></table>'
+ '</form>';

Sorry, maybe i can not take your suggestion, since the dynamic table is
generated by another person, what i can use is only the object which is
fetsched by
var table = document.getElementById(tablename)

of course i can get HTML through table.innerHTML, but there are too
many things to change, i can not afford such a big operation.

What the hell is wrong with setAttribute()??

thanks anyway

(We have a form in content div already, then add elements to the form.)

I don't know, they said it should be avoided.
exefile.setAttribute('type', 'file'); // Try change thid too.

Hi, thanks man,

With removing the weird setAttribute method, it works now under IE. I
dont know why the javascirpt ppl wrote these stuffs whereas they can
not work!

Thanks a lot!

I searched somehow in internet, and got these information, maybe that
will be helpful for someone who has the same problem as me:

// we want an onclick on this button for
example
field.onclick = functionName;

Don't use setAttribute and getAttribute, except when there is no other

way

to do what you want to do.

I wouldn't go that far, since the W3C DOM prescribes
setAttribute()/getAttribute() as the way to write/read attribute values.

True, but in practice I found that many problems can be avoided by
avoiding
set/getAttribute when possible. It's about the only more or less
general
rule I found for using the W3C DOM, so I repeat it whenever I have the
chance.
That said, setAttribute() doesn't work for event handlers in IE (Win/Mac).
For some reason IE doesn't resolve the value to the function object, so
nothing happens at event time.
Well well, interesting. I didn't know that.
It does work in Mozilla, however, and can be
beneficial in some cases: creating an event handler call that passes
arguments consisting of values assembled in the script setting the
attribute (rather than relying on the event object's properties for
details).
I hadn't thought of that.
In any case, to assign (or reassign) an event handler on the fly, event
handler property assignment, as shown above, is the way to go if you need
to serve IE in your audience browser mix.

<plug type="shameless">

On my W3C DOM mailing list (http://www.xs4all.nl/~ppk/js/list.html) we
often
discuss problems like this one. Event handler registration, especially,

turns out to be a rather problematical area with many small browser
problems.

If you're interested in getting the DOM to work in all browsers you
might
consider joining the list, as many JavaScript developers have done
before
you.
