Resizing images

[philweb]

Hi,

I posted this about a week ago and Bpat responded to give me some help, since then I haven't seen him on the forum and so I am asking again for some help with my problem - I hope you don't mind.

Here is a script that uploads the image and stores it in the db, but the resizing part doesn't work, the image just displays at it's original size. Bpat said that I would need to configure the resizing part to get it to work with the other part but this is where things go wrong, you see I don't know enough php to figure our how to do this. Can anyone help with debugging the script so it will resize and upload please.

Thanks as always,

Phil

Here is the script so far.

// This page allows users to upload files to the server. 

// Set the page title and include the HTML header. 
$page_title = 'Upload a File'; 


if (isset($_POST['submit'])) { // Handle the form. 

require_once ('../mysql_connect.php'); // Connect to the database. 


//Start of Bpat's script to resize
 function manipImage($width=250) 
{ 
// Get the temporary file name that php gives us. 
$tempname = $_FILES['photo']['tmp_name']; 

// Check to make sure it's uploaded 
if(is_uploaded_file($tempname)) 
{ 
// Original dimensions 
$orig_dimensions = getimagesize($tempname); 

// Check to make sure we get a valid image size 
if($orig_dimensions === FALSE || $orig_dimensions[2] != 2) 
die("Image upload failed!!"); 

// Define the original dimensions (width & height) 
$orig_width = $orig_dimensions[0]; 
$orig_height = $orig_dimensions[1]; 

// Create a new image from the temp to work off of 
$orig_image = imagecreatefromjpeg($tempname); 

// If it's tall, we need to do one more step 
$image_is_tall = ($orig_height>=$orig_width); 

$swidth = $width; 

// Define the proportionate height 
$sheight = ceil($orig_height*$swidth/$orig_width); 

// If the image is tall, not wide, well rotate the image dimensions 
// This is so that it stays proportionate if it's a tall image 
if($image_is_tall) 
{ 
$t = $swidth; 
$swidth = $sheight; 
$sheight = $t; 
} 

// Create a new image based on the new widths & height 
$new_image = imagecreatetruecolor($swidth, $sheight); 

// Now we'll copy the old image, to the new image and it will be resized 
if(imagecopyresampled($new_image, $orig_image, 0, 0, 0, 0, $swidth, $sheight, $orig_width, $orig_height) === FALSE) 
return -1; 
else 
{ 
// Set up some variables to use 
$photo_name = $_POST['photosID'].'.jpg'; 
$imgPath = 'family_pics/images/'.$photo_name; 
$photo_dir='/philweb/public_html/'.$imgPath; 
$photo_url='http://www.mysite.co.uk/'.$imgPath; 

$newer_image = $photo_dir.$photo_name; 

// Create a new jpeg (*.jpg) from the resized image with 100% quality 
if(@imagejpeg($new_image, $newer_image, 100) === FALSE) 
return false; 
else 
return true; 
} 
} 
} 
// end of bpat's script to resize
