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/jpeg' => 'JPEG',
                        'image/gif' => 'GIF',
                        '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']) ) 
{
        if($photos_uploaded['size'][$counter] > 0)
        {
            if(!array_key_exists($photos_uploaded['type'][$counter], $known_photo_types))
            {
                $result_final .= "File ".($counter+1)." is not a photo<br />";

:o::):D That's awesome!! That did it.. that worked... you just showed that I have a lot to learn about PHP! Thank you very very much ...

 

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.
