File upload... Need help with extention and to loop....

[GremlinP1R]

Can some one please HELP ME.......

Okay got it to work but the extention is a problem.... for some reason it does not pick it up....
This is what I have...

[code]<?php
// Validation of File Extension
  function validate_extension() {
 
  // Section #1 - Defining variabels
      $file_name = trim($this -> file_name);
  $extension = strtolower(strrchr($file_name, "."));
  $ext_array = $this -> ext_array;
  $ext_count = count($ext_array);
 
  // Section #2 - Validate File Name and Extension
      if (!$file_name) {
      return false; }
  else {
    if (!$ext_array){
    return true;}
else {
    foreach ($ext_array as $value) {
        $first_char = substr($value, 0, 1);
    if ($first_char <> ".") {
    $extensions[] = "." .strtolower($value); }
    else {
      $extensions[] = strtolower($value); }
  }
 
  // Section #3 - Loop using right extension - Check for acceptance
      foreach ($extensions as $value) {
    if ($value == $extension) {
    $valid_extension = "TRUE" ;
    }
  }
 
  // Section #4 -
      if ($valid_extension) {
    return true; }
    else {
      return false;}
        }  
      }
  }
?>[/code]

it keeps on telling me that the extention is undefined.... and the how do I make this loop??

[code]<?php
// When Submitting
  if (isset($_POST['Submit'])) {
  include('uploadclass.php');
 
  // Set upload info
      $upload_class = new Upload_Files;
  $upload_class -> temp_file_name = trim($_FILES['pic1']['tmp_name']);
  $upload_class -> file_name = trim(strtolower($_FILES['pic1']['name']));
  $upload_class -> upload_dir = "images/cars/";
  $upload_class -> upload_log_dir = "images/uploadlog/";
  $upload_class -> max_file_size = 500000000;
  $upload_class -> banned_array = array(" ");
  $upload_class -> ext_array = array(" .jpg");
 
  // Calling class Functions
//      $valid_ext = $upload_class -> validate_extension();
  $valid_size = $upload_class -> validate_size();
  $valid_user = $upload_class -> validate_user();
  $max_size = $upload_class -> get_max_size();
  $file_size = $upload_class -> get_file_size();
  $upload_directory = $upload_class -> get_upload_directory();
  $upload_log_directory = $upload_class -> get_upload_log_directory();
  $upload_file = $upload_class -> upload_file_no_validation();
?>[/code]
