File Rename

[princeofpersia]

Hi

 

As i am a newbie, i finally been able to upload and resize an image, but i need to rename the files to random numbers, i have found a code but i dont know where i should have to embed it in my php can u please tell me where and how?

 

 

this is my php

 

if (isset($_POST['register']) && $_POST['register'])
{
$update = mysql_query("UPDATE agents SET credit= credit-1 WHERE username='$username'");
	//image1
	$nameone=$_FILES['myfileone']['name'];
	if ($nameone)

	{
		$dst_filename = resize_upload_image($_FILES['myfileone'], "images/");
		if ($dst_filename !== false) {
			extract($dst_filename);
			$image1 = mysql_query ("UPDATE img SET image1='$img_filename', thumb1='$thumb_filename'");
		}
	}


function resize_image($srcfilename, $dstfilename, $new_width, $new_height)
{
$ext = strtoupper(pathinfo($srcfilename, PATHINFO_EXTENSION)); 
// JPEG image 

if(is_file($srcfilename) && ($ext == "JPG" OR $ext == "JPEG")) 
{ 
	// Get src dimensions
	list($width, $height) = getimagesize($srcfilename);

	// Resample
	$image_p = imagecreatetruecolor($new_width, $new_height);
	$image = imagecreatefromjpeg($srcfilename);
	imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

	// Output
	imagejpeg($image_p, $dstfilename, 100);
	return TRUE;
} 
// PNG image 
elseif(is_file($srcfilename) && $ext == "PNG") 
{ 
	// Get src dimensions
	list($width, $height) = getimagesize($srcfilename);

	// Resample
	$image_p = imagecreatetruecolor($new_width, $new_height);
	$image = imagecreatefrompng($srcfilename);
	imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

	// Output
	imagepng($image_p, $dstfilename, 0);
	return TRUE;
}
return false;
}

function resize_upload_image($file, $path)
{
global $standard_width, $standard_height;
global $thumb_width, $thumb_height;

$img_name= $file['name'];
$tmp_name= $file['tmp_name'];
if ($img_name)
{
	if (substr($path, strlen($path)-1) != "/") {
		$path .= "/";
	}

	$original_img_name = $path."tmp-".$img_name;
	move_uploaded_file($tmp_name, $original_img_name);
	$img_location = $path.$img_name;
	$thumb_location = $path."thumb-".$img_name;

	if (resize_image($original_img_name, $img_location, $standard_width, $standard_height) === FALSE) {
		unlink($original_img_name);
		return false;
	}
	if (resize_image($original_img_name, $thumb_location, $thumb_width, $thumb_height) === FALSE) {
		unlink($original_img_name);
		return false;
	}
	unlink($original_img_name);
	return array("img_filename"=>$img_location, "thumb_filename"=>$thumb_location);
}
return false;
}

 

sp this is a time id which could be added

 

$image_name=time().'.'.$extension;

$filename = "img/". $image_name;

$filename1 = "img/small_". $image_name;

If I understand your question right, you want to know what to edit in which function, to rename the files to random numbers.

As I see it the resize_upload_image() function creates two files, a thumbnail and an image.

So to rename them to random numbers you would have to edit the variables thumb_location and img_location as following:

 

$random_number = rand(0,999); // The random number, you wanna set as suffix.
$img_location = $path.$img_name."-".$random_number;
$thumb_location = $path."thumb-".$img_name."-".$random_number;

 

Hope you can use it pal
