Laravel 4 - Get first image of images in file input array before uploading

Question

I have this file input:

<input type="file" name="images[]" accept="image/*" multiple />

In my controller I upload them this way:

 $x = 0;
 foreach(Input::file('images') as $file) {

                    $filename = $x.'.'.$file->guessClientExtension();
                    //dest, name
                    if (!file_exists($thepath)) {
                        mkdir($thepath, 0777, true);
                    }
                    $uploadflag = $file->move($thepath,$filename);

                    $is_main = ($x==0) ? true : NULL; //Know who's first img

                    $img_submit = DB::table('images')->insert(array(
                        'image_id'          => $filename,
                        'is_main'           => $is_main
                    ));

                    if($uploadflag) {
                        $uploadedfiles[] = $filename;
                    }
                $x++;
 }

I have a plugin wich sorts them out the way I want, if I do a print_r to the form I get:

Array (
[title] => 
[images] => Array
    (
        [0] => 2.png
        [1] => 1.png
        [2] => 3.png
        [3] => 4.png
        [4] => 5.png
    )

[submit] => Submit
)

You can notice that the image with the name 2.png (wich I sorted it to be first) is being accomodated in the position [0] of the array as expected. But when I try to upload it I get the variable $is_main set to another image. How can I indentify in the array position [0] to be the main image?

I've tried iterating with $x so that when $x is 0 in the foreach loop I set the first image to be the main one, but looks like in the process the array gets "dissacomodated"

EDIT: If you could at least tell me how to get the first image in the array in PHP I would easily know how to do it with Laravel :-)

Use reset()

$files = Input::file('images');

foreach($files  as $file):

        $filename = $x.'.'.$file->guessClientExtension();

        # Destination, Name
        if (!file_exists($thepath))
            mkdir($thepath, 0777, true);

        $uploadflag = $file->move($thepath,$filename);

        # reset() files to see if current file is the first one
        $is_main = ($file == reset($files)) ? true : NULL;

        $img_submit = DB::table('images')->insert([
            'image_id' => $filename,
            'is_main'  => $is_main
        ]);

        if($uploadflag) 
            $uploadedfiles[] = $filename;

endforeach;

Looks like a good solution but It's not working this way unfortunately :(

Why is it not working for you? What is the issue? try $files[0] == $file

I can successfully upload the images and store them to database, but what I want is to set the first image ( in the array would be position[0] ) as the main one so $is_main would be set to TRUE, I tried your code but I still get the same result - the images are stored in the order I uploaded them but not in the order I arranged them with this plugin: bit.ly/1BPGG8v (Example #4)

Yep that was it, I lost the sorting functionality.... Hmm, thanks ALOT for your help, I'll try to figure this out somehow :/

@Daniel your best bet is to implement AJAX the way the plugin was designed.
