Upload Multiple images

1

Hi guys,

Need help uploading some images. I need to upload 4 and then get their location etc.

I used this script in the past to upload a single image :



?php
//define a maxim size for the uploaded images in Kb
 define ("MAX_SIZE","10240"); 

//This function reads the extension of the file. It is used to determine if the file  is an image by checking the extension.
 function getExtension($str) {
         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
 }

//This variable is used as a flag. The value is initialized with 0 (meaning no error  found)  
//and it will be changed to 1 if an errro occures.  
//If the error occures the file will not be uploaded.
 $errors=0;
//checks if the form has been submitted
 if(isset($_POST['Submit'])) 
 {
 	//reads the name of the file the user submitted for uploading
 	$image=$_FILES['image']['name'];
 	//if it is not empty
 	if ($image) 
 	{
 	//get the original name of the file from the clients machine
 		$filename = stripslashes($_FILES['image']['name']);
 	//get the extension of the file in a lower case format
  		$extension = getExtension($filename);
 		$extension = strtolower($extension);
 	//if it is not a known extension, we will suppose it is an error and will not  upload the file,  
	//otherwise we will do more tests
 if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
 		{
		//print error message
 			echo "<p><b>Warning!</b></p><p>Unknown extension! Please try again.</p> <p>Pleae use: <b> .jpg , .jpeg , .png  or .gif</b></p>";
 			$errors=1;
 		}
 		else
 		{
//get the size of the image in bytes
 //$_FILES['image']['tmp_name'] is the temporary filename of the file
 //in which the uploaded file was stored on the server
 $size=filesize($_FILES['image']['tmp_name']);

//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*1024)
{
	echo "<p><b>Warning!</b></p><p>You have exceeded the size limit! Please try again.</p>";
	$errors=1;
}

//we will give an unique name, for example the time in unix time format
$image_name=time().'.'.$extension;
//the new name will be containing the full path where will be stored (images folder)
$newname="../images/".$image_name;
$dbNewname = "images/".$image_name;
//we verify if the image has been uploaded, and print error instead


$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied) 
{
	echo "<p><b>Error!</b></p><p>Upload unsuccessfull! Please try again.</p>";
	$errors=1;
}}}}

//If no errors registred, print the success message

  if(isset($_POST['Submit']) && !$errors) 
 {
 	echo "<h1>File Uploaded Successfully! Try again!</h1>";
 }

It works very well, in all honesty though, I didn’t write it and I got it off a site ages ago. Is it possible to modify it to upload more images with it? Or will have to be something from scratch? I’ve had a play with it with the best of my knowledge, but haven’t had any success so I thought I’d ask for some help here.

Thanks.
