I'm trying to use this script known as SimpleImage.php that can be found here <a href="http://www.white-hat-web-design.co.uk/articles/php-image-resizing.php">link</a> I'm trying to include what is on the bottom of the page to my existing script can anyone help me I've tried several ways but its not working.

<?php 
session_start();
error_reporting(E_ALL);
ini_set('display_errors','On');

//error_reporting(E_ALL); 


// image upload folder
    $image_folder = 'images/classified/'; 
// fieldnames in form
$all_file_fields = array('image1', 'image2' ,'image3', 'image4');
// allowed filetypes
$file_types = array('jpg','gif','png');
// max filesize 5mb
$max_size = 5000000;
//echo'<pre>';print_r($_FILES);exit;

$time = time();
$count = 1;

foreach($all_file_fields as $fieldname){ 
	if($_FILES[$fieldname]['name'] != ''){

		$type = substr($_FILES[$fieldname]['name'], -3, 3);

		// check filetype
		if(in_array(strtolower($type), $file_types)){

			//check filesize
			if($_FILES[$fieldname]['size']>$max_size){
				$error = "File too big. Max filesize is ".$max_size." MB";

			}else{

				// new filename	
				$filename = str_replace(' ','',$myusername).'_'.$time.'_'.$count.'.'.$type;

				// move/upload file
				$target_path = $image_folder.basename($filename);
				move_uploaded_file($_FILES[$fieldname]['tmp_name'], $target_path);

				//save array with filenames
				$images[$count] = $image_folder.$filename;
				$count = $count+1;

			}//end if

		}else{ $error = "Please use jpg, gif, png files";

		}//end if
	}//end if
}//end foreach



if($error != ''){ echo $error;	
}else{

1) Save that code to a file named 'simple_image.php' (recommend in an 'includes' directory)

2) either include or require_once that file in the script you want to use it in

3) create an instance of the SimpleImage class

4) use the member functions of the class to resize the image

My script alone works corks correctly but I can't seem to find the correct way to include this

include('SimpleImage.php');
      $image = new SimpleImage();
      $image->load($_FILES['uploaded_image']['tmp_name']);
      $image->resizeToWidth(150);
      $image->output();

into my script. My script uploads the image to a file directory, but I want to resize the image and then upload the image to the destination folder. Does anyone know how to write it in to script?

Try this:  May not work the first time around cause it is UN-TESTED!

<?php 
session_start();
error_reporting(E_ALL);
ini_set('display_errors','On');
include('SimpleImage.php');
      $image = new SimpleImage();    
//error_reporting(E_ALL); 


// image upload folder
    $image_folder = 'images/classified/'; 
// fieldnames in form
$all_file_fields = array('image1', 'image2' ,'image3', 'image4');
// allowed filetypes
$file_types = array('jpg','gif','png');
// max filesize 5mb
$max_size = 5000000;
//echo'<pre>';print_r($_FILES);exit;

$time = time();
$count = 1;

foreach($all_file_fields as $fieldname){ 
	if($_FILES[$fieldname]['name'] != ''){

		$type = substr($_FILES[$fieldname]['name'], -3, 3);

		// check filetype
		if(in_array(strtolower($type), $file_types)){

			//check filesize
			if($_FILES[$fieldname]['size']>$max_size){
				$error = "File too big. Max filesize is ".$max_size." MB";

			}else{

				// new filename	
				$filename = str_replace(' ','',$myusername).'_'.$time.'_'.$count.'.'.$type;

				// move/upload file
				$image->load($_FILES['uploaded_image']['tmp_name']);
				if($image->getWidth() > 150) { //if the image is larger that 150.
					$image->resizeToWidth(150); //resize to 150.
				}
				$target_path = $image_folder.basename($filename); //image path.

				$image->save($target_path); //save image to a directory.					

				//save array with filenames
				$images[$count] = $image_folder.$filename;
				$count = $count+1;

			}//end if

		}else{ $error = "Please use jpg, gif, png files";

		}//end if
	}//end if
}//end foreach



if($error != ''){ echo $error;	
}else{

The same happen to me

Getting errors:

Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in /../SimpleImage.php on line 28

 

Warning: imagesx(): supplied argument is not a valid Image resource in /../SimpleImage.php on line 60

 

Warning: imagejpeg(): supplied argument is not a valid Image resource in /../SimpleImage.php on line 40

It means you didn't supply a filename (or a blank filename). The other two errors are because obviously you can't make an image out of nothing.

Just change

$image->load($_FILES['uploaded_image']['tmp_name']);

to

$image->load($_FILES[$fieldname]['tmp_name']);
