Creating thumbs

[Woodburn2006]

i have a script that creates thumbnails from an uploaded img. this script works when i have the script on a page in a folder and the imgs being created in subfolders within the root folder that the php file is stored.

 

the problem i am having is that when i want to create the images and put them into a different folder on a lower level of the site map it just creates black images.

 

for example: the structure of my site map is;

 

ROOT FOLDER

- img

-- gallery

--- lrg (where the lrg version of the img is)

--- temp (where the temporary img is uploaded)

--- thumbs (where the thumb will be saved)

 

- content

 

- cp

-- images (where add.php is)

 

what i want to do is have the function beingcalled in add.php and for the files to be stored in the lrg and thumbs folders within the img folder. i have tried using paths etc to do this but it still does not work.

 

here is the function:

function createthumb($name,$filename,$new_w,$new_h)
{
	$system=explode('.',$name); // split filename either side of the '.'
	if (preg_match('/jpg|jpeg/',$system[1])){ // if extension is jpg or jpeg
		$src_img=imagecreatefromjpeg($name); // create a copy of the image in jpg
	}
	if (preg_match('/png/',$system[1])){ // if extension is png
		$src_img=imagecreatefrompng($name); // create a copy of the image in png
	}
	$old_x=imageSX($src_img); // gets width of original image
	$old_y=imageSY($src_img); // gets height of original image
	if ($old_x > $old_y) { // if img is wider than high
		$thumb_w=$new_w; // sets width variable of new img
		$thumb_h=$old_y*($new_h/$old_x); // sets height variable by doing: height = original width * (100 / original height)
	}
	if ($old_x < $old_y) { // other way around from setting wider than high
		$thumb_w=$old_x*($new_w/$old_y);
		$thumb_h=$new_h;
	}
	if ($old_x == $old_y) { // if img is square sets variabls straight forwardly
		$thumb_w=$new_w;
		$thumb_h=$new_h;
	}
	$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h); // creates image
	imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); // copies into new image
	if (preg_match("/png/",$system[1])) // if old file extension is png
	{
		imagepng($dst_img,$filename); // extension of new image is png
	} else {
		imagejpeg($dst_img,$filename); // else extension of new image is jpeg or jpg
	}
	imagedestroy($dst_img); //destroys variable
	imagedestroy($src_img); 
}

 

here is add.php:

<?
$function = ((isset($_GET['function']))?($_GET['function'])''));
if($function=="add"){

	if ($_FILES['uploadedfile']['name'] !=""){

		$pic1=$_FILES['uploadedfile']['name'];
		$target_path = "/customers/ontherocks.me.uk/ontherocks.me.uk/httpd.www/img/gallery/temp/";
		$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
		if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
			$nm = '1';
			$new_img = "http://www.ontherocks.me.uk/img/gallery/temp/$pic1";
			$thumb = "/customers/ontherocks.me.uk/ontherocks.me.uk/httpd.www/img/gallery/thumbs/$pic1";
			createthumb($new_img,$thumb,100,100);
		}else{
			echo "There was an error uploading the file, please try again!";
		}
	}else{
		$nm = '0';
		echo "No New Picture Added!<br><br>";
	}

if ($nm=='1'){
	//if ($_SERVER['REQUEST_METHOD'] == "POST"){
	//	$sql  = " INSERT INTO gallery ";
		//$sql .= " (name, price, status, width, height, description, img) VALUES ";
		//$sql .= " ('$name', '$price', '$status', '$width', '$height', '$description', '$img') ";
		//$result = mysql_query($sql, $connection);
		//if (mysql_error()) { print "Database ERROR: " . mysql_error(); }



		echo "
			The File Has Been Added!
			";
	}


}else{

	echo"
		<div id='news_add'>
			<form id='news_new' method='post' action='/cp/index2.php?go=img_add&function=add' enctype='multipart/form-data'>
				<br /><strong>Add Image</strong><br /><br />
				<input name='uploadedfile' type='file' size='80%'>
				<label>
				<input type='submit' id='img_submit' value='Submit' class='submit'>
				</label>
				<br /><br />
			</form>
		</div>";

}
?>
