Question

Here is the code I’m using to upload Multiple Photos with the HTML5 tag.

foreach($_FILES['files']['tmp_name'] as $key => $tmp_name){
    $rand_file_name = rand(1,1000000);
    if ($_FILES['files']['type'][$key] == "image/jpeg" || $_FILES['files']['type'][$key] == "image/gif" || $_FILES['files']['type'][$key] == "image/png" || $_FILES['files']['type'][$key] == "image/JPEG" || $_FILES['files']['type'][$key] == "image/GIF" || $_FILES['files']['type'][$key] == "image/PNG") {
        if ($_FILES['files']['size'][$key] < 512000){
            move_uploaded_file($tmp_name, "../../../assets/users/$user_id/photos/$browser_album_id/$rand_file_name.jpg");
            $photo_name = $_FILES['files']['name'][$key];
            $photo_name = str_replace(".jpg", "", $photo_name);
            $photo_name = str_replace(".png", "", $photo_name);
            $photo_name = str_replace(".gif", "", $photo_name);
            $insert_database = mysql_query("INSERT INTO photo_album_photos (random_photo_name,belonging_album_id,photo_name) VALUES ('$rand_file_name','$browser_album_id','$photo_name')");
            $num_files_added++;
        }
    }
}

The $num_files_added will count how many files were added.

what I would like to achieve is to gather the $rand_file_name(s) into an array. Each image is given a random name, so one image could be 812532.jpg and the next maybe 246546.jpg.

I would like to insert the file names into the database an array. So the above examples would be in an array. e.g. array(812532,246546);

Of course, I don’t want anyone to code this straight up for me, just help and guidance! 🙂

Answer 1

Before the foreach, introduce a variable $file_names = array(); as a blank array

and in the foreach loop, try this :

$file_names[] = $rand_file_name;

Then, you can access the array that will be stored in the $file_names variable. 🙂

To make them into a comma separated string

Introduce $file_names = '' before the foreach loop.

Then in the loop, do this :

$file_names .= $rand_file_name . ',';

And after closing the foreach loop, this :

$file_names = substr($file_names,0,-1);
