PHP - Cant Create A File? What Is Wrong?

So, I'm learning how to upload pictures into a system from my awesome PHP book. I've looked and looked through the script but I can't figure out whats wrong with it.

Goal:
The script is meant to save a full version of the image in the images folder and a thumbnail in the thumbnail folder.
Bug:
The full image does not appear in any folder, and the thumbnail is created but its put in the images folder.

I've checked the GD library, and everything is supported.

Any help appreciated.

Hello!
I am trying to code one part of my functions list, but when I run the function to test all if, elseif, and else statements, it always goes to the else statement. So basically it tries to connect to MySQL, retrieve a username, and check to see if it is active, banned, or inactive. It is always saying it is active, even when I change it's status to inactive via PHPMyAdmin. Here is the code:
Code: [Select]
<?php

function checkActive() {

$checkActiveQuery = mysql_query("SELECT * FROM users WHERE user=adf");

if ($checkActiveQuery == "INACTIVE"){
echo "Your account has not been activated. If you have not recieved, or have misplaced the activation email, please contact the administrator.";
}
elseif ($checkActiveQuery == "BANNED"){
echo "You have been banned from our social network. If you believe this is an error, please contact the administrator.";
}
else {
echo "Your account is active.";
}
}
?>
The username I am testing with is "adf" without quotes. But, when I change its status to INACTIVE, it still says it's still active, same with banned. How do I make it retrieve this data from MySQL and it function properly? It seems that it is unable to retrieve this data specifically.

Thanks!
Nick.

I have this code:
Code: [Select]
<?php
include_once 'dbinfo.php';
if(isset($_POST['submit'])) {
$label = $_POST['label'];
$stm = $connect->prepare("INSERT INTO words VALUES (?)");//$stm = $connect->prepare("INSERT INTO words VALUES (?,?)");
$stm->bind_param('s', $label);//$stm->bind_param('ss', $label, $user);
$stm->execute();
printf("%d Label inserted.\n", $stmt->affected_rows);
$stm->close();
$connect->close();

}
?>
<form action="" name="submit_label" method="POST">
<p>Submit a Label:<input type="text" name="label" value=""></p>
<input name="submit" type="submit" value="Submit label">
<p></p>
<a href="wordlist.php" >The List of labels</a>
</form>The content inside dbinfo.php is this
Code: [Select]
<?php

$dbhost = 'localhost';

$dbuser = 'user';

$dbpass = 'password';

$dbname = 'labels';

$connect = new mysqli($dbhost, $dbuser, $dbpass, $dbname);

if(!$connect) 

{

die('Connection failed: ' . $mysqli->error());

}

?>Why do I get a blank page when I run the code? It won't insert into table either.

Hello am new to php and am working with a config file.

But it always give me a wrong path to file

/homedomains/xxxxx/public_html/

no / between home an domains.. am frustrated on how to solve this... please help me in this an attaching the script file.. config file too

I'm using a php $_POST variable as the name of a file that I want to create.  fopen() , according to my understanding open the file if it exists or creates it if it doesn't.   
$Ref = $_POST['Ref'];
I using each reference element of $Ref as the name of a file in a certain directory.  So if $Ref[$i] exists as a file name in a certain directory, append to the file, if it doesn't create the file in that directory and write to it.   Do I use the file path of the file within fopen()?  fopen(./References/$Ref,a) or  fopen(./References/$Ref,w)?
