  • 0

i have this code that submits multiple files and titles im trying to combine the results to upload to my DB and check if title[] is empty and print a custom value but im having problems with the title[] i need to combine with the s_upload[] array:

<?php
if ( $_SERVER['REQUEST_METHOD'] == 'POST' ){

foreach ($_FILES["s_upload"]["error"] as $key => $error) {
    if ($error == UPLOAD_ERR_OK) {
        $tmp_name = $_FILES["s_upload"]["tmp_name"][$key];
        $name = $_FILES["s_upload"]["name"][$key];
       // move_uploaded_file($tmp_name, "data/$name");

       if ($_POST['title']==''){
       echo 'Title';
       }else{
       print_r ($_POST['title']);
       echo $name;
       }
    }
}   
}
?>

    Since you didn’t specify where the 1111 came from, I’ll give you a few options:

    <?
if ( $_SERVER['REQUEST_METHOD'] == 'POST' ){
    foreach ($_FILES["s_upload"]["name"] as $key => $name) {
        if ($_FILES["s_upload"]["error"][$key] == UPLOAD_ERR_OK) {
            $tmp_name = $_FILES["s_upload"]["tmp_name"][$key];

            if ($_POST['title'][$key]==''){
                // No title was specified: construct default title
                // This defaults the title to the filename of the file that was uploaded
                $title = $name;
                // This defaults the title to some random 32-character hex string
                $title = md5(time()+rand()); 
            }
            else{
                // A title was specified in the input box: use it
                $title = $_POST['title'][$key];
            }
            echo "$title $name<br />";
        }
    }
}
?>

    Here’s what I changed:

    1. I’m now looping over the name instead of the error. It just makes a lot more sense to do it this way. Looping over the error was a source of confusion.
    2. Since you named your inputs using an array (the []) in the input name, you have to specify which one you’re referring to in your code. This means you need to use $key consistently throughout.
    3. You said you wanted a default title when one wasn’t specified, but didn’t explain how you want it constructed. I threw two random ideas in there. The first defaults to the filename of the uploaded file. The second is just a random string. You could change this to something based off the current time, the IP of the uploader, etc. etc. In any case, you’d do it there.
