Depends on the type of input field. For the most part, you can simply set the value attribute of an input field:

<input type="text" name="firstName" value="Nikolai" />
<input type="hidden" name="id" value="5" />

For radio buttons, you already set the value of each radio. To make sure one of them is checked, use the checked attribute:

<input type="radio" name="gender" value="m" checked="true" />
<input type="radio" name="gender" value="f" />

For dropdown lists, you can preselect one (or more, if your dropdown is multiple) options by using the selected attribute:

<select name="languages" multiple="yes">
<option value="English" selected="true">English</option>
<option value="Spanish" selected="true">Spanish</option>
<option value="French">French</option>
<option value="Greek" selected="true">Greek</option>
</select>


Now that you know the HTML required to pre-populate form fields, it shouldn't be too difficult to write the PHP to generate this.

Actually, (and I'm sorry because I'm not feeling well!!) I just realized after rereading your original post that you're not interested in prepopulating just ANY form input field, but one of type "file".

The file input type also includes a value attribute, but it's not supported by most browsers. I guess you're out of luck, unless it can be done with javascript. I tried, but couldn't get it to work.

I suppose that this is a GOOD THING, since you really wouldn't want some website to be able to use javascript to pre-populate a file input field.

Imagine if it that was supported -- you could visit a web page that pre-populated a file upload form with a password file. Javascript can automatically submit the form to the server. The server can then begin a brute-force attack on your password file and crack all your system passwords.


Maybe it's better that you can't prepopulate a file input field...
