file input

just a quick query...

does anyone know a way of uploading multiple files, i just cant figure out how they do it, like the hotmail site lets you do when u attach files.

also when i upload a file, does it only exist during the execution of the script that i pass it to? can someone explain teh procedure.. is it php or apache that puts the file in a temp dir or what?

thanks for any comments

for multiple uploads you can either name each upload field yourself or create an array that prints our each file field, x times, then send all those files as an array, then do a foreach on it and grap the data

yeah, just set the input name like for example this:

File 1: <input type="file" name="file[]"><br>
File 2: <input type="file" name="file[]"><br>
File 3: <input type="file" name="file[]"><br>

PHP will then create an array like this:

$_POST['file'][0] <- file 1
$_POST['file'][1] <- file 2
$_POST['file'][2] <- file 3

To make it "dynamic", you can use a foreach, like Ben said.

foreach ($_POST['file']) {
do that thang here
}
