How can i set a predefined file name like
<input type="text" name="text1" size="10" value="something" >

Can i do this?

of course you can do that, but if you're doing this in an upload script, then I would do like this:

// data here
copy($_FILES['file']['tmp_name'],"dir/".$DecidedName);

So what is exactly the html code?
Because i read in a tutorial for html and especially upload forms that there is no any attribute like VALUE as in other INPUT types.

Could you give me more details?

any ideas?

this is the upload form:

<form action="upload.php" enctype="multipart/form-data" method="post">
<input type="file" name="UserFile">
<input type="submit" value="Upload">
</form>

upload.php

<?php

// i've left out the steps that will check the filetype and so on...

copy($_FILES['UserFile']['tmp_name'],"DirName/".$NewName".extension");

?>

i think that you didn't understand what i asked for.

I mean the case that you have already upload a file and rename it to the id of a table, so say that you have a post with the id of the file name.

When you push the edit button you have the opportunity to modify all the forms that consist of the values of the fields in the database.

Something like it

Can i do something like that to a upload form?

No, you can't set a default for a file input field. The browser won't allow you to do so because of security issues. Which is a good thing, if you think about it. If they allowed it, then what's to stop a malicious web developer from setting a default for the file field like c:\windows\default.pwl and then auto submitting it using javascript?

If I understand what you wrote correctly, I have ran into the same problem before. You have some entry in a db, which contains file names and/or files which you want to be able to edit with a form... and a field in the form is a file field. I worked around that similar to this:


// input filed looks like this <input type="file" name="file">
if ($file != "") {
// code to update the entry in the db
}

That way if they don't want to change the file then they leave the field blank and it doesn't do anything... if they do submit a new file, $file is not equal to "", and therefore the code runs to update it.

Hope this helps.
