Script does not upload any files

[WilliamNova]

So I'm making an upload file for my website for users to upload images. However, it's not working and I have no clue why. This is the entire php script for this page becuase I'm not sure what could be causing it.

<?php
include ( './includes/header.php' );

if (isset($_FILES['channel_pic'])) {
   if (($_FILES['channel_pic']['type']=='image/jpeg') || ($_FILES['channel_pic']['type']=='image/png') || $_FILES['channel_pic']['type']=='image/gif') {
   $chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';                                                                             
   $random_directory = substr(str_shuffle($chars), 0, 15);

   if (file_exists('data/channels/images/icons/' . $random_directory . ''.$_FILES['channel_pic']['name'])) {
     echo 'image exists';
   }
   else
   {
   move_uploaded_file($_FILES['channel_pic']['tmp_name'],'data/channels/images/icons/' . $random_directory . ''.$_FILES['channel_pic']['name']);

   }
   }
   if (($_FILES['channel_pic']['type']=='image/jpeg') || ($_FILES['channel_pic']['type']=='image/png') || $_FILES['channel_pic']['type']=='image/gif') {

   }
   else
   {
    die('Invalid File'); 
   }

}
?>

So, let's see. The die function won't work when I upload, say a .RAW format. And it should upload any jpeg's, png's, or gif's to a randomly created directory. Which it's not doing. The folders do exist --> data/channels/images/icons

the $_FILES array is empty when you try to upload a file that is larger than the post_max_size setting. $_FILES['channel_pic'] won't be set and all your code is bypassed. you need to test for this condition first.

 

next, even if you upload a file smaller than the post_max_size setting, the upload can fail with an error. you must test if $_FILES['channel_pic']['error'] is set and equal to (an == comparison) a zero to insure that the upload actually worked. you can also test if $_FILES['channel_pic']['error'] is exactly equal to (an === comparison) a zero to combine both tests into one.

I found the error and I should have looked more closely at my form, which I didn't even think was the problem.

<form action='upload_image.php' method='POST' encytype='multipart/form-data'>

Spelled enctype wrong.

cannot help you with parts of the relevant code you didn't put in your post and spelling errors are not really programming problems anyway.
