Php Admin应用程序与表单

Hello stackoverflow people, For the last Two days ive been trying to create this Staff applying system but i'm not to great at PHP and still learning but what i want it to do is they fill the forms out then click Submit then that downloads to a folder on the server With dated file names for each application for me to look over but i cant figure it out... My PHP only goes so far.. Is this system possible? can you make it for me or help me out?? Thanks alot for reading! :)

Clarified Image here

<?php
$tasktitle = $_POST['app'];
setlocale(LC_TIME, "fi_FI"); 
date_default_timezone_set("Europe/Helsinki");
$date = strftime("%Y-%m-%d-%A");
$timesaved = strftime("%H:%M:%S");
$elapsedtime = $_POST['current_time'];
$file = "apps/".$date.".txt";
$cont = 'time finished: '.$timesaved.' - time elapsed: '.$elapsedtime.' - task name: '.$tasktitle.''. "n"; 

$f = fopen ($file, 'a+');
fwrite($f, $cont);
fclose($f);
?>

But it just writes a date in the file lol

</div>

This is a example where Post data is stored in a Dated text file line by line.

<form  method="POST">
    <input name="name" type="text" />
    <input name="ign" type="text" />
    <input type="submit" name="submit" value="Save Data">
</form>

<?php
if(isset($_POST['name']) && isset($_POST['ign'])) {
    $data = $_POST['name'] . '-' . $_POST['ign'] . "
";
    $date = date('Y-m-d');
    $ret = file_put_contents('apps/'.$date.'.txt', $data, FILE_APPEND | LOCK_EX);
    if($ret === false) {
        die('There was an error writing this file');
    }
    else {
        echo "$ret bytes written to file";
    }
}
?>

EDIT 1:

If you want to create a new file for every entry with dated filename use this code -

if(isset($_POST['name']) && isset($_POST['ign'])) {
    $data = $_POST['name'] . '-' . $_POST['ign'] . "
";
    $i = 1;
    $new_file_name = date('Y-m-d');
    while (file_exists('apps/' . $new_file_name . '.txt')) {
        $new_file_name = (string) $new_file_name . '_' . $i;
        $i++;
    }
    $ret = file_put_contents('apps/' . $new_file_name . '.txt', $data, FILE_APPEND | LOCK_EX);
    if ($ret === false) {
        die('There was an error writing this file');
    } else {
        echo "$ret bytes written to file";
    }
}
