Load multiple files using HTML5 and PHP

Question

I am trying to load multiple files using HTML5. This is my code I found on some site. In the PHP code it doesn't recognize it as an array.

Am I doing something wrong? Can someone show me a working solution?

Thanks.

index.html

<form action='save.php' method='post' enctype='multipart/form-data'>
<input name="uploads" type="file" multiple="multiple" />
<input type='submit' value="Upload File">
</form>

save.php

function GetFiles() {
        $files = array();
        $fdata = $_FILES["uploads"];
        if (is_array($fdata["name"])) {//This is the problem
                for ($i = 0; $i < count($fdata['name']); ++$i) {
                        $files[] = array(
                            'name' => $fdata['name'][$i],
                            'tmp_name' => $fdata['tmp_name'][$i],
                        );
                }
        } else {
                $files[] = $fdata;
        }

        foreach ($files as $file) {
                // uploaded location of file is $file['tmp_name']
                // original filename of file is $file['file']
        }
}

Answer 1

You need to make some sort of array of the name:

<input name="uploads[]" type="file" multiple="multiple" />

Just like you used to do when using checkboxes.

Answer 2

form variables that are arrays must be named with a [], otherwise PHP doesn't see it as an array. So:

<form action='save.php' method='post' enctype='multipart/form-data'> 
<input name="uploads[]" type="file" multiple="multiple" /> 
<input type='submit' value="Upload File"> 
</form> 

should do it.

Answer 3

I know this is kind of a old thread but I use this little script to convert the (to me) confusing layout of the $_FILES array to a more readable form. Name_input is whatever name you gave to the Input object in HTML.

for($i=0; $i<count($_FILES['name_input']['name']); $i++) {
    $betterfiles[] = array(
        "name" => $_FILES['name_input']['name'][$i],
        "type" => $_FILES['name_input']['type'][$i],
        "tmp_name" => $_FILES['name_input']['tmp_name'][$i],
        "error" => $_FILES['name_input']['error'][$i],
        "size" => $_FILES['name_input']['size'][$i]
    );
}
