Uploading Images Help

andrew_biggart · October 28, 2010

Ok I have finally got rid of my syntax errors with this upload script. Now im getting the error uploading your image.

My folders are called project_files and project_thumbs.

This is my script

<?php
	$results = "";

	error_reporting(E_ALL);
    ini_set("display_errors", 1);

	//Auto Thumbnail Function
	function create_thumbnail($source,$destination, $thumb_width) {
	$size = getimagesize($source);
	$width = $size[0];
	$height = $size[1];
	$x = 0;
	$y = 0;
	if($width> $height) {
		$x = ceil(($width - $height) / 2 );
		$width = $height;
	} elseif($height> $width) {
		$y = ceil(($height - $width) / 2);
		$height = $width;
	}
	$new_image = imagecreatetruecolor($thumb_width,$thumb_width)
		or die('Cannot initialize new GD image stream');
	$extension = get_image_extension($source);
	if($extension=='jpg' || $extension=='jpeg')
		$image = imagecreatefromjpeg($source);
	if($extension=='gif')
		$image = imagecreatefromgif($source);
	if($extension=='png')
		$image = imagecreatefrompng($source);

	imagecopyresampled($new_image,$image,0,0,$x,$y,$thumb_width,							       
    $thumb_width,$width,$height);
	if($extension=='jpg' || $extension=='jpeg')
		imagejpeg($new_image,$destination);
	if($extension=='gif')
		imagegif($new_image,$destination);
	if($extension=='png')
		imagepng($new_image,$destination);

	}

	//Get Extension Function
	function get_image_extension($name) {
	$name = strtolower($name);
	$i = strrpos($name,".");
	if (!$i) { return ""; }
		$l = strlen($name) - $i;
	$extension = substr($name,$i+1,$l);
	return $extension; 
	}

	//Random Name Function
	function random_name($length) {
	$characters = "abcdefghijklmnopqrstuvwxyz01234567890";
	$name = "";

	for ($i = 0; $i < $length; $i++) {
		$name .= $characters[mt_rand(0, strlen($characters) - 1)];
	}
	return "image-".$name;
}



$images_location = "/project_files/";
$thumbs_location = "/project_thumbs/";
$thumb_width = "100";
$maximum_size = "5000000";			

//Check And Save Image			
if($_POST) {

if($_FILES['image']['name'] == ""){
	$results = "Please select the image you would like to upload by clicking browse";
}
else{
	$size=filesize($_FILES['image']['tmp_name']);
	$filename = stripslashes($_FILES['image']['name']);
	$extension = get_image_extension($filename);
	if($size > $maximum_size) {
		$results = "Your file size exceeds the maximum file size!";
	}
	else

	if (($extension != "jpg") &&
		($extension != "jpeg") &&
		($extension != "png") &&
		($extension != "gif")) {
		$results = "Only the following extensions are allowed. 'jpg', 'jpeg', 'png', 'gif'.";
	}
	else {
		$image_random_name=random_name(15).".".$extension;
		$copy = @copy($_FILES['image']['tmp_name'], $images_location.$image_random_name);
		if (!$copy) {
			$results = "Error while uploadin your image! Please try again!";
		}
		else{
		create_thumbnail($images_location.$image_random_name,$thumbs_location.$image_random_name, $thumb_width);
			$results = "Your image has been uploaded!";
		}
	}
}
}
?>

and the form

<html>
<head>
<title>test</title>
</head>
<body>
<?php echo $results; ?>
<form action="#" method="post" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="5000000" />
    <input type="file" name="image" />
    <input type="submit" value="Upload Image" />
</form>
</body>
</html>

The @ on the copy() statement is hiding any php errors that would tell you why it is failing.

Code should never have @ in it to hide errors (there's no need anyway because you would have display_errors set the way you want to show or not show error messages to the client.)

Ok I have removed the @ but I am still getting the same thing, Error while uploadin your image! Please try again!

So the image is not saving but why?

I have also checked the file permissions of all the folders and they are all 777!!!

Is the form on the same page as the php code so that any php errors would be seen?
