This is a complete script I am using that creates 3 different re-sized images from my original upload. Right now it renames the 3 output files with their size plus the original image file name. I want to rename the images with the size BUT change it to a different name that would be a value in a string called.
$ListingId= $_GET['ListingId']; (I'm grabbing the value from the url)
This is my index page
<?php
include( 'function.php');
// settings
$max_file_size = 1024*200; // 200kb
$valid_exts = array('jpeg', 'jpg', 'png', 'gif');
// thumbnail sizes
$sizes = array(100 => 100, 150 => 150, 250 => 250);
if ($_SERVER['REQUEST_METHOD'] == 'POST' AND isset($_FILES['image'])) {
if( $_FILES['image']['size'] < $max_file_size ){
// get file extension
$ext = strtolower(pathinfo($_FILES['image']['name'], PATHINFO_EXTENSION));
if (in_array($ext, $valid_exts)) {
/* resize image */
foreach ($sizes as $w => $h) {
$files[] = resize($w, $h);
}
} else {
$msg = 'Unsupported file';
}
} else{
$msg = 'Please upload image smaller than 200KB';
}
}
?>

This is the function.php code
/**

* @param int $height
*/
function resize($width, $height){
/* Get original image x y*/
list($w, $h) = getimagesize($_FILES['image']['tmp_name']);
/* calculate new image size with ratio */
$ratio = max($width/$w, $height/$h);
$h = ceil($height / $ratio);
$x = ($w - $width / $ratio) / 2;
$w = ceil($width / $ratio);
/* new file name */
$path = 'uploads/'.$width.'x'.$height.'_'.$_FILES['image']['name'];
/* read binary data from image file */
$imgString = file_get_contents($_FILES['image']['tmp_name']);
/* create image from string */
$image = imagecreatefromstring($imgString);
$tmp = imagecreatetruecolor($width, $height);
imagecopyresampled($tmp, $image,
0, 0,
$x, 0,
$width, $height,
$w, $h);
/* Save image */
switch ($_FILES['image']['type']) {
case 'image/jpeg':
imagejpeg($tmp, $path, 100);
break;
case 'image/png':
imagepng($tmp, $path, 0);
break;
case 'image/gif':
imagegif($tmp, $path);
break;
default:
exit;
break;
}
return $path;
/* cleanup memory */
imagedestroy($image);
imagedestroy($tmp);
}
Any help is greatly appreciated! Credit to the original writer of the code Resalat Haque.
The new file name is set in the resize() function to the width and height and uploaded file name.
/* new file name */
$path = 'uploads/'.$width.'x'.$height.'_'.$_FILES['image']['name'];
If you want to rename it you can pass the new name to the resize() function and change the function to
function resize($width, $height, $newFileName){
/* Get original image x y*/
list($w, $h) = getimagesize($_FILES['image']['tmp_name']);
/* calculate new image size with ratio */
$ratio = max($width/$w, $height/$h);
$h = ceil($height / $ratio);
$x = ($w - $width / $ratio) / 2;
$w = ceil($width / $ratio);
/* new file name */
$path = 'uploads/'.$width.'x'.$height.'_'.$newFileName;
/* read binary data from image file */
$imgString = file_get_contents($_FILES['image']['tmp_name']);
/* create image from string */
$image = imagecreatefromstring($imgString);
$tmp = imagecreatetruecolor($width, $height);
imagecopyresampled($tmp, $image,
0, 0,
$x, 0,
$width, $height,
$w, $h);
/* Save image */
switch ($_FILES['image']['type']) {
case 'image/jpeg':
imagejpeg($tmp, $path.'.jpg', 100);
break;
case 'image/png':
imagepng($tmp, $path.'.png', 0);
break;
case 'image/gif':
imagegif($tmp, $path.'.gif');
break;
default:
exit;
break;
}
return $path;
/* cleanup memory */
imagedestroy($image);
imagedestroy($tmp);
}
Change the function call to:
$newFileName = 'newName'; // set to your desired value
/* resize image */
foreach ($sizes as $w => $h) {
$files[] = resize($w, $h, $newFileName);
}
Edit: Also need to add the file type extension to $path in the switch.
