Problem with uploading images to my localhost

[zhiyuan]

Hello, so here is my code for this add score, images php. but when i click the submit bottom the images won't go to the pointed folder thats under my website root folder.

1st question: could this be a permission limited on the read and write of images? i'm using mac osx

2nd question:Is that why i keep getting echo"please enter all infor" from the if statement because the images is not correctly upload?

3th question: on define(''GW_UPLOADPATH','/Library/WebServer/Documents/gw/images/'); do i have to type in the location of where the images folder is or the DW will know exactly where to save it since the folder is in the same as the web folder

thank you for your time

 
 
<?php
define('GW_UPLOADPATH','/Library/WebServer/Documents/gw/images/');
 
if(isset($_POST['submit'])){
    $name=$_POST['name'];
    $score=$_POST['score'];
    $screenshot=$_FILES['screenshot']['name'];
    echo "filename is $screenshot";
 
if(!empty($name)&& !empty($score)){
    $target=GW_UPLOADPATH.$screenshot;
    echo "Moving file to $target";
 
    if(move_uploaded_file($_FILES['screenshot']['tmp_name'], $target)){
 
        $dbc=mysqli_connect('localhost','***','****','guitar');
 
        $query="insert into guitarwars values(0, now(),'$name','$score','$screenshot')";
        mysqli_query($dbc, $query);
 
        echo'<p>Thankys for adding your new high score!</p>';

What errors are you getting?
Where is the working directory in relation to

 define(''GW_UPLOADPATH','/Library/WebServer/Documents/gw/images/');

hello green light. i just figure it out, with help from my buddy. my problem was i didn't give the permission for target folder. my solution was:

1. go to terminal (i use mac)

2. go under my gw (web folder)
for some reason i can't not use the original root name and the group name, so i change it to www:www

3. sudo chown www:www images/ (hit enter, enter password and boom. Is done and done.)

but i have one more question, why can't i use the default root name and the group name? instead i have to change it to www:www?
