[rajeevthomas]

Hi everyone... please help me with this. I have a gallery that I am working on. Part of that are two files upload.php and preupload.php which upload pics. And it does its job successfully BUT it shows an error 'Notice: Undefined offset: 9 in C:\wamp\www\upload.php on line 34' My line 34 is 

if($photos_uploaded['size'][$counter] > 0)

. My whole code for the upload.php is

 

<?php
    include("config.inc.php");

    // initialization
    $result_final = "";
    $counter = 0;

// List of our known photo types
    $known_photo_types = array(
                        'image/pjpeg' => 'jpg',
                        'image/jpeg' => 'jpg',
                        'image/gif' => 'gif',
                        'image/bmp' => 'bmp',
                        'image/x-png' => 'png'
                    );
   
// GD Function List
    $gd_function_suffix = array(
                        'image/pjpeg' => 'JPEG',

                        'image/bmp' => 'WBMP',
                        'image/x-png' => 'PNG'
                    );

// Fetch the photo array sent by preupload.php
    $photos_uploaded = $_FILES['photo_filename'];

// Fetch the photo caption array
    $photo_caption = $_POST['photo_caption'];

    while( $counter <= count($_FILES['photo_filename']['tmp_name']) )

Your while goes one increment too many. Should be.....

 

while( $counter < count($_FILES['photo_filename']['tmp_name']))

Just gotta remember that arrays start at 0. So if you have an array with 10 indexes within it, the highest index number will be 9 not 10.
