File Upload php syntax error - php

Question

I'm trying to make this code work again. I did something that made in not echo even the file name I'm trying to access. Please help, I've been looking at this for over an hour already with no avail :(
Note: I can't even echo out the $name in here
<?php
error_reporting(0);
if($_POST['submit']){
//file uploading
$name = basename($_FILES['upload']['name']); //name plus extention
print_r($_FILES['upload']);
$t_name = $_FILES['upload']['tmp_name'];
$dir = 'gallery_i';
$thumbs = 'gallery_t';
if(move_uploaded_file($t_name,$dir.'/'.$name)){
$resizeObj = new resize($dir.'/'.$name);//Resize image (options: exact, portrait, landscape, auto, crop)
$resizeObj -> resizeImage(200, 200, 'auto'); //Save image
$resizeObj -> saveImage($thumbs.'/'.$name, 100);
echo 'file upload nicely';
//file upload successfull
}
}
?>
<div class='home'>
<form method='post' action='other.php'>
Name: <input class='reg' type='text' name='prodname'/><br/><br/>
Description:<br/> <textarea class='reg' name='description' rows="4" cols="40"> </textarea> <br/><br/>
<input type='file' name='upload' />
<input type='submit' value='submit' name='submit'/>
</form>
</div>

Answer 1

You need to use mutlipart form data to upload files:
set the form attribute: enctype="multipart/form-data"

Answer 2

The echo only executes if move_uploaded_file($t_name,$dir.'/'.$name) returns true. In your case, it is returning false.
You need to determine if
the file exists (file_exists($t_name))
is readable (is_readable($t_name))
the target directory is writable (is_writable($dir))
no file with the same name already exists (!is_file($dir . '/' . $name))
Only when those conditions are true will move_uploaded_file complete successfully.
As noted by benedict_w, you also need to modify your HTML form to add the attribute enctype with a value of multipart/form-data.

Turn on php's error reporting/display options. Running with those off while develping/debugging is a lot like running a marathon on the side of a cliff at midnight while wearing a blindfold.
In your php.ini:
display_errors: 1
error_reporting: E_ALL
As well, your script will never work. For file uploads to even have a chance of succeeding, you need to specify
<form method="post" action="other.php" enctype="multipart/form-data">
^^^^^^^^^^^^^^^^^^^^^^^^^^^^--- missing
and you're assuming the upload has succeeded. At bare minimum you should have:
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if ($_FILES['upload']['error'] === UPLOAD_ERR_OK) {
.... your file handling code
} else {
die("Upload failed with error code " . $_FILES['upload']['error']);
}
}
