Question

I have several input fields for uploading files:

<input type=file name=logo />
<input type=file name=userfile />
<input type=file name=userfile1 />
.
.
.
<input type=file name=top />
<input type=file name=bottom />

Every file needs to be treated in some different way. How can I check if $_FILES starts, for example, with userfile?

Answer 1

If you have mroe userfiles you can change your html marqup to

<input type=file name=userfile[1] />
<input type=file name=userfile[2] />

And then in PHP

foreach($_FILES['userfile'] as $i => $file) {
    processing
}

Othervise you can check if name starts with expected string (http://php.net/manual/en/function.substr.php)

<?
    if(substr($inputName, 0, 7) === "userfile")
?>
