I've got a page where the user can upload an avatar/photo. Once it uploads, it isn't updated for the user. It either shows the old image that was already there, or shows a broken image. What is wrong with my code. How can I get it to update the most recent image uploaded upon hitting submit?
Thanks.
PHP Code:
<?php
session_start();
if (isset($_SESSION['username'])){
$username = $_SESSION['username'];
$upload = $_POST['upload'];
include('inc/connect.php');
$uploadsql = mysql_query("SELECT * FROM `users` WHERE `username`='$username'");
$uploadrow = mysql_fetch_assoc($uploadsql);
$id = $uploadrow['id'];
$avatar = $uploadrow['avatar'];
$folder = "avatars/";
$avatarshow = '<img src="avatars/' . $avatar . '" width="65" height="65" />';
if ($upload)
{
// Name of file
$name = $_FILES["image"]["name"];
// Type of file (video/avi) or image/jpg, etc
$type = $_FILES["image"]["type"];
//size of file
$size = $_FILES["image"]["size"];
//stores file in a temporary location
$temp = $_FILES["image"]["tmp_name"];
// if there is an error
$error = $_FILES["image"]["error"];
// function genRandomString() {
// $characters = '0123456789abcdefghijklmnopqrstuvwxyz';
// $length = 10;
// $string = '';
// for ($p = 0; $p < $length; $p++) {
// $string .= $characters[mt_rand(0, strlen($characters))];
// }
// return $string;
// }
if ($error > 0)
{
$uploaderror = "An error occured. Please try again.";
}
else
{
if ($type=="image/jpg" || $type=="image/png" || $type=="image/gif" || $type=="image/bmp" || $type=="image/jpeg")
{
if ($size <= 1048576)
{
//if(file_exists("avatars/".$name)){
if ($type=="image/jpeg"){
$extension = ".jpg";
}
if ($type=="image/jpg"){
$extension = ".jpg";
}
if ($type=="image/png"){
$extension = ".png";
}
if ($type=="image/bmp"){
$extension = ".bmp";
}
if ($type=="image/gif"){
$extension = ".gif";
}
//$name1 = genRandomString($string);
$ext = $extension;
$name = $id.$ext;
//}
// unlink deletes the file so a new file can be uploaded in its place
unlink('avatars/' . $avatar);
$uploadquery = mysql_query("UPDATE users SET avatar='$name' WHERE username='$username'");
move_uploaded_file($temp, "avatars/".$name);
$success = "Upload Complete!";
}
else{
$uploaderror = "Your image must be less than 1 megabytes.";
}
}
else
{
die("That format is not allowed!");
}
}
}
}
else{
