I'm trying to code a registration form. But I'm stuck at adding a borrowed code of image upload, resize, save and store its path in MySQL database. The error message is "Undefined index: fileimage" on the line where I have this code: if($_FILES['fileimage']['name']).

Here is the register.php:

<?php



    // include configuration file

    require("../includes/config.php");



    //Class import for image uploading

    include("../includes/upload_class.php");



    // if form was submitted

    if ($_SERVER["REQUEST_METHOD"] == "POST")

    {

        // validate submission

        if (empty($_POST["firstname"]))

        {

            apologize("Provide your first name.");

        }

        if (empty($_POST["lastname"]))

        {

            apologize("Provide your last name.");

        }

        if (empty($_POST["username"]))

        {

            apologize("Provide a username.");

        }

        if (empty($_POST["sex"]))

        }

        else if (empty($_POST["password"]))

Undefined index usally mean the name attr is incorrect or missing when sending post. If not, you could try

if(isset($_FILE['fileimage']['name']){
// code
}

This will chekc if post has fileimage set apon submission.

Example PHP Code
This script resize an Image into two 60px and 25px. Take a look at $newwidth you have to modify size values.

        $extension = getExtension($filename);
  $extension = strtolower($extension);
 if (($extension != "jpg") && ($extension != "jpeg")

  {

$errors=1;
  }
 else
{
   $size=filesize($_FILES['file']['tmp_name']);

Thanks, but I need to get the script I posted to work, as it works on a site I know.

Before addressing your problem, please allow me to point out minor problem with your class. It might be minor now because like you said it is working on the other site that you know, but it can be a major problem sooner than later.

The upload class was written for the old PHP version with backward compatibility for the PHP 4.x.x versions. I don't think there are many servers these days still running on 4.x.x version.

The solution is to rewrite it to PHP 5.x.x compliant class. I know some readers coming from other languages would say "What the _ell Veedeoo is talking about?". This may sound like a Bull _hit to a few practitioner of the laguage, but I am pretty sure it is not. I will not waste my precious time typing all these crapola just for the purpose of delivering my BS. I don't do that kind of stuffs. My time is important as much as I value the time of others reading my opinions, analysis and suggestions on the subject matter before me.

Classes written in PHP with backward compatibility was written similar to the class written in JAVA. There is no constructor. The constructor rules in the old PHP version was to create a method with the same name of the class itself.

The old way

class MyClass{

    var $var1;
    var $var2 = 'var two';
    var $var3;

    function MyClass(){
        $this->var1 = $var1;
        $this->var2 = $var2;
        }

    function method1(){

       return $this->var2;

   }    
 }       

Class variable members are now called properties. These properties are defined with its appropriate visibility under the descretion of the programmer e.g. private, public, public static and protected. All methods are now defined with their apropriate visibilities.

The new way

class MyClass{

    private $var1;
    private $var2 = 'var two';
    private $var3 ;

    ## or
    /*
      private $var1, $var2, $var3;  
   */
   ## or 
   /*
       public $var1;
       public $var2;
       public $var3;
   */

   public function __construct(){
       $this->var1 = $var1;
       $this->var2 = $var2;

      }

   public function method1(){

       return $this->var2;

   }

   public static static_method(){

       return $this->var2;

  } 

}

this

 public static static_method(){
    return $this->var2;
    } 

should read

 public static function static_method(){
    return $this->var2;
    } 

@veedeoo,
You're totally correct; the class was written for a very old version of PHP, and the thought has always worried me. However, I'm not fluent enough to rewrite class.

Can you or any other person help me out, even if at a cost?

I don't charge people for providing them with the help I could possibly provide. However, you can donate for the cause of Daniweb.

Then you can post the source code here.

@veedeoo,
A million thanks for agreeing to help me out. I've just donated a little sum to the Daniweb cause. I downloaded the the latest upload_class.php from

http://www.finalwebsites.com/snippets.php?id=7

However, I think the code need to be updated to the PHP 5.5 version. As follows is the upload_class.php:

Please, be advised that the register.php has some nice-working, custom PHP functions like render, apologize and query. I would want to resize the image (160px x 160px) before saving it. The original image needs to be deleted from the server. The path to each image needs to be saved in the database and linked to right user. I've already created users and file_table DB tables, but I need guidance on how to associate a user to his/her photo.

I reiterate my appreciations for your kind help.
