PHP - Referencing A Dll

Hi

I am in the process of converting to Object Oriented from Procedural. To cater for this I have built an admin_login function, contained within a class: 'siteFunctions'.

However, I am having trouble pointing the admin form to the function correctly.

Every time I click 'submit', the form does not process anything. It doesn't even 'think' about it i.e. show the egg timer....

I have built this script heaps of times using the procedural method, so I guess I am somehow doing something wrong with respect to referencing the action attribute of the form (due to my new approach).

I am very new to OO so please go easy on me: I know the script isn't particularly advanced. I just want to get used to putting functions into classes, and then calling the code, before I move onto more advanced stuff.

I have placed all of the files within the same folder in order to rule out driectory path issues.

Here are the three scripts that I think are relevant (login, functionsClass, and the mysql connection script):

Login

 
$pageTitle = "Admin Login";
include("admin_header.php");
include_once("sitefunctions.php");
new siteFunctions();
echo '<div class="admin_main_body">';   


       <form action="<?php echo htmlentities($_SERVER["PHP_SELF"]);?>" method='post'>
       <input type="text" name="username" id="username" size="20">
       <label>Username</label><br />
       <input type="password" name="password" id="password" size="20">
       <label>Password</label><br />
       <input type="submit" name="submit" id="submit" value="submit">
       </form>

echo '<div>';
include("includes/admin_footer.php");


sitefunctions.php

 
 //$page = "admin_index.php";
 class siteFunctions {
     var $message;
     function admin_login() {
 echo '<div class="admin_main_body">';
 $message = NULL;
 if (isset($_POST['submit'])) {
     require_once ("mysql_connect.php"); 
 if (empty($_POST['username'])) {
 $u = FALSE;
 $message .= '<p> Please enter your username </p>';
} else {
$u = escape_data($_POST['username']);
}
if (empty($_POST['password'])) {
$p = FALSE;
$message .= '<p>You forgot to enter your password </p>';
} else {
$p = escape_data($_POST['password']);
     }

if ($u && $p) { // If everything's OK.
$query = "SELECT * FROM admin WHERE username= ('$u') AND password=('$p')";
$result = @mysqli_query($GLOBALS["___mysqli_ston"], $query);
$row = mysqli_fetch_array($result,  MYSQLI_BOTH); 
if ($row) { 
session_start();
$_SESSION["admin_id"] = $row[0];
//header("$page"); //Redirects user to admin_index.php
//header('location: "$page"');
header ("Location:  http://" . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . "admin_index.php");  

//echo '$_SESSION["admin_id"]';
}
else {
$message = '<p> The username and password combination are incorrect.</p>'; 
}
((is_null($___mysqli_res = mysqli_close($GLOBALS["___mysqli_ston"]))) ? false : $___mysqli_res);
} else {
$message .= '<p>Please try again.</p>';
}
}
if (isset($message)) {
echo '<font color="red">', $message, '</font>';
}
//$adminLogin = 'admin_login';
} //Closes function
} //Closes class


Connection Script

 
// This file contains the database access information. This file also establishes a connection to MySQL and selects the database.

// Set the database access information as constants.
DEFINE ('DB_USER', 'atkinson');
DEFINE ('DB_PASSWORD', 'XYZ111WA');

DEFINE ('DB_NAME', 'practicesite');

if ($dbc = @($GLOBALS["___mysqli_ston"] = mysqli_connect(DB_HOST,  DB_USER,  DB_PASSWORD))) { // Make the connnection.

if (!((bool)mysqli_query($GLOBALS["___mysqli_ston"], "USE " . constant('DB_NAME')))) { // If it can't select the database.

// Handle the error.
my_error_handler (((is_object($GLOBALS["___mysqli_ston"])) ? mysqli_errno($GLOBALS["___mysqli_ston"]) : (($___mysqli_res = mysqli_connect_errno()) ? $___mysqli_res : false)), 'Could not select the database: ' . ((is_object($GLOBALS["___mysqli_ston"])) ? mysqli_error($GLOBALS["___mysqli_ston"]) : (($___mysqli_res = mysqli_connect_error()) ? $___mysqli_res : false)));

// Print a message to the user, include the footer, and kill the script.
echo '<p><font color="red">The site is currently experiencing technical difficulties. We apologize for any inconvenience.</font></p>';
include_once ('includes/footer.php');
exit();

} // End of mysql_select_db IF.

} else { // If it couldn't connect to MySQL.

// Print a message to the user, include the footer, and kill the script.
my_error_handler (((is_object($GLOBALS["___mysqli_ston"])) ? mysqli_errno($GLOBALS["___mysqli_ston"]) : (($___mysqli_res = mysqli_connect_errno()) ? $___mysqli_res : false)), 'Could not connect to the database: ' . ((is_object($GLOBALS["___mysqli_ston"])) ? mysqli_error($GLOBALS["___mysqli_ston"]) : (($___mysqli_res = mysqli_connect_error()) ? $___mysqli_res : false)));

include_once ('includes/footer.php');
exit();

} // End of $dbc IF.

// Function for escaping and trimming form data.
function escape_data ($data) { 
global $dbc;
if (ini_get('magic_quotes_gpc')) {
$data = stripslashes($data);
}
return mysqli_real_escape_string( $dbc, trim ($data));
} // End of escape_data() function.


Any help would be appreciated.

The script for creating a new file name for the image:

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
		$target_path = $target_path . $new_image_name;//set the target path with a new name of image

The script creates a new file like:

f6c9b8d9db05366c3504210cded9ddb2.jpg

and moves the file to the "uploads" folder. And then the script also creates a thumbnail with the same file name and moves the file to the "thumbs" folder.   The issue I am having is that the same ID code could happen again for a different image in the database, thus I would be calling a different original sized image than the thumbnail image.   My question is: How to avoid this issue of the same ID code has happened again for a different file. What is the proper way to reference the anchor tag of the thumbnail image to its actual original sized image?   With the script I have the thumbnail image would be coming from the "thumbs" folder and the anchor tag would get referenced to the "uploads" folder to get the original sized image.
