Hi guys I am trying to use image magick with php to draw an image but when i run the script it doens't show anything. All I get is an a blank page. Does anyone know if I am doing this right.

Here is my code.
Code: [Select]
<?php
echo "<pre>";
system("type convert"); 
echo "</pre>";
?>
<br />
<br />
<br />
<br />
<br />
<?php
exec("/usr/bin/convert -size 200x200 xc:black -stroke black -strokewidth 1 \\
-fill white -draw \"circle 100,100 100,10 \" \\
-fill black -draw \"circle 100,100 100,30 \" \\

?>

My results are these:

convert is /usr/bin/convert


I really need some help with this. I haven't been able to find anything online.

I wonder whether someone may be able to help me please.

I'm trying to put together a PHP within Aurigma Image Uploader which will create an image gallery. To do this I need to extract the image from a folder called 'Thumbnails' and image data from a file called 'files.xml'.

The code below is an extract of the default script that performs this functionality and I've tested and it works without any issues.

Code: [Select]
<?php 
   
  //This variable specifies relative path to the folder, where the gallery with uploaded files is located. 
  //Do not forget about the slash in the end of the folder name. 
  $galleryPath = 'UploadedFiles/'; 
    
  $thumbnailsPath = $galleryPath . 'Thumbnails/'; 
    
  $absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR; 
    
  $descriptions = new DOMDocument('1.0'); 
  $descriptions->load($absGalleryPath . 'files.xml'); 
?>
I have now changed my folder and file structure to the following:

UploadedFiles (Folder)
username (Subfolder containing the 'location' folder) location (Subfolder containing 'Thumbnails folder and image, and 'files.xml') Please note that both the 'username' and 'location' folders are dynamically created when the user initially uploads the images.
To try and accomodate the new file structure I changed my code to:

Code: [Select]
<?php 
   
  //This variable specifies relative path to the folder, where the gallery with uploaded files is located. 
  //Do not forget about the slash in the end of the folder name. 
  $galleryPath = 'UploadedFiles/'; 
    
  $absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR . $usernamefolder . DIRECTORY_SEPARATOR . $locationfolder . DIRECTORY_SEPARATOR; 
  
  $thumbnailsPath = $galleryPath . 'Thumbnails/'; 
  
  $descriptions = new DOMDocument('1.0'); 
  $descriptions->load($absGalleryPath . 'files.xml'); 
?>
But when I run this I receive the following error:

Quote

d333603417/htdocs/development/UploadedFiles/files.xml" in /homepages/2/d333603417/htdocs/development/gallery.php on line 14

Line 14 is this line:
Code: [Select]
$descriptions->load($absGalleryPath . 'files.xml');

I've been working on this for days and I just can't seem to find the answer.

I just wondered whether someone could possibly look at this and let me know where I'm going wrong.

If it helps, I've added the upload script below.

Code: [Select]
<?php
require_once 'Includes/gallery_helper.php'; 
require_once 'ImageUploaderPHP/UploadHandler.class.php'; 
$galleryPath = 'UploadedFiles/';

  $location = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $_POST['locationid']); 
  $dirName = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $_POST['folder']); 
 
  $absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR . $username . DIRECTORY_SEPARATOR . $location . DIRECTORY_SEPARATOR; 
  $absThumbnailsPath = $absGalleryPath . 'Thumbnails' . DIRECTORY_SEPARATOR; 
 
  if (!is_dir($absGalleryPath)) mkdir($absGalleryPath, 0777, true); 
  chmod($absGalleryPath, 0777); 
  if (!is_dir($absGalleryPath . $dirName)) mkdir($absGalleryPath . $dirName, 0777, true); 
  chmod($absGalleryPath . $dirName, 0777); 
 
  if ($uploadedFile->getPackage()->getPackageIndex() == 0 && $uploadedFile->getIndex() == 0) 
    initGallery($absGalleryPath, $absThumbnailsPath, FALSE); 
 
  $originalFileName = $uploadedFile->getSourceName(); 
  $files = $uploadedFile->getConvertedFiles(); 
  $sourceFileName = getSafeFileName($absGalleryPath, $originalFileName); 
  $sourceFile = $files[0]; 
 
  if ($sourceFile) $sourceFile->moveTo($absGalleryPath . $sourceFileName); 
  $thumbnailFileName = getSafeFileName($absThumbnailsPath, $originalFileName); 
  $thumbnailFile = $files[1]; 
  if ($thumbnailFile) $thumbnailFile->moveTo($absThumbnailsPath . $thumbnailFileName); 
  
  $descriptions = new DOMDocument('1.0', 'utf-8'); 
  $descriptions->load($absGalleryPath . 'files.xml'); 
  
  $xmlFile = $descriptions->createElement('file'); 
  // <-- please check the following line 
  $xmlFile->setAttribute('name', $_POST['folder'] . '/' . $originalFileName); 
  $xmlFile->setAttribute('source', $sourceFileName);

  $xmlFile->setAttribute('description', $uploadedFile->getDescription()); 
  $xmlFile->setAttribute('username', $username); 
  $xmlFile->setAttribute('locationid', $locationid); 
  $xmlFile->setAttribute('folder', $dirName); 
 

  $descriptions->documentElement->appendChild($xmlFile); 
  $descriptions->save($absGalleryPath . 'files.xml'); 
} 
 
$uh = new UploadHandler(); 
$uh->setFileUploadedCallback('onFileUploaded'); 
$uh->processRequest(); 
?>

This script allows you to take an image and only show parts of it. This script works great, but there's one problem. As I add more and more to a page, it takes longer and longer to load.

http://openzelda.thegaminguniverse.com/wiki/index.php5?title=OZWiki:Alien_Invasion

There will be a lot more php images added soon. I used this method so I don't have to upload a ton of images at once.
So is there a way to speed things up? Is it possible to have it save cache so the images don't reload everytime you refresh the page?

I wonder whether someone may be able to help me please.

I've put together the following script which saves user defined images to server folders using the Aurigma Image Uploader software.

Code: [Select]
<?php
require_once 'Includes/gallery_helper.php'; 
require_once 'ImageUploaderPHP/UploadHandler.class.php'; 
$galleryPath = 'UploadedFiles/'; 
 
function onFileUploaded($uploadedFile) { 
  global $galleryPath; 
 
  $packageFields = $uploadedFile->getPackage()->getPackageFields(); 
  $username=$packageFields["username"]; 
  $locationid=$packageFields["locationid"]; 
  $usernamefolder = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $_POST['username']); 
  $locationfolder = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $_POST['locationid']); 
  $dirName = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $_POST['folder']); 
 
  $absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR . $usernamefolder . DIRECTORY_SEPARATOR . $locationfolder . DIRECTORY_SEPARATOR; 
  $absThumbnailsPath = $absGalleryPath . 'Thumbnails' . DIRECTORY_SEPARATOR; 
 
  if (!is_dir($absGalleryPath)) mkdir($absGalleryPath, 0777, true); 
  chmod($absGalleryPath, 0777); 
  if (!is_dir($absGalleryPath . $dirName)) mkdir($absGalleryPath . $dirName, 0777, true); 
  chmod($absGalleryPath . $dirName, 0777); 
 
  if ($uploadedFile->getPackage()->getPackageIndex() == 0 && $uploadedFile->getIndex() == 0) 
    initGallery($absGalleryPath, $absThumbnailsPath, FALSE); 
 
  $originalFileName = $uploadedFile->getSourceName(); 
  $files = $uploadedFile->getConvertedFiles(); 
  $sourceFileName = getSafeFileName($absGalleryPath, $originalFileName); 
  $sourceFile = $files[0]; 
 
  if ($sourceFile) $sourceFile->moveTo($absGalleryPath . $sourceFileName); 
  $thumbnailFileName = getSafeFileName($absThumbnailsPath, $originalFileName); 
  $thumbnailFile = $files[1]; 
  if ($thumbnailFile) $thumbnailFile->moveTo($absThumbnailsPath . $thumbnailFileName); 
  
  $descriptions = new DOMDocument('1.0', 'utf-8'); 
  $descriptions->load($absGalleryPath . 'files.xml'); 
  
  $xmlFile = $descriptions->createElement('file'); 
  // <-- please check the following line 
  $xmlFile->setAttribute('name', $_POST['folder'] . '/' . $originalFileName); 
  $xmlFile->setAttribute('source', $sourceFileName); 
  $xmlFile->setAttribute('size', $uploadedFile->getSourceSize()); 
  $xmlFile->setAttribute('originalname', $originalFileName); 
  $xmlFile->setAttribute('thumbnail', $thumbnailFileName); 
  $xmlFile->setAttribute('description', $uploadedFile->getDescription()); 
  $xmlFile->setAttribute('username', $username); 
  $xmlFile->setAttribute('locationid', $locationid); 
  $xmlFile->setAttribute('folder', $dirName); 
 

  $descriptions->documentElement->appendChild($xmlFile); 
  $descriptions->save($absGalleryPath . 'files.xml'); 
} 
 
$uh = new UploadHandler(); 
$uh->setFileUploadedCallback('onFileUploaded'); 
$uh->processRequest(); 
?>
This code saves the files in the following structu

UploadedFiles (Pre-existing folder)
'username' (Subfolder created dynamically on image upload if it doesn't already exist. This folder contains the 'location' folder) 'location' (Subfolder created dynamically on image upload if it doesn't already exist. This contains original image, 'files.xml' and 'Thumbnails' folder) 'Thumbnails' (Subfolder created dynamically on image upload if it doesn't already exist. This contains thumbnail of original image)
I'm now trying to put together a script which creates an image gallery, with those images pertinent to the current user and location. The code below is the piece of my script which deals with the loading of the images.

Code: [Select]
<?php 
  $galleryPath = 'UploadedFiles/'; 
    
  $thumbnailsPath = $galleryPath . 'Thumbnails/'; 
    
  $absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR; 
    
  $descriptions = new DOMDocument('1.0'); 
  $descriptions->load($absGalleryPath . 'files.xml'); 
?>
The initial problem I had, was resolved from guidance I received on this site, and that was to find the correct 'realpath' of the 'Thumbnails' folder and 'files.xml'
These are as follows: Quote

/homepages/2/d333603417/htdocs/development/UploadedFiles/IRHM73/1

  and Quote

/homepages/2/d333603417/htdocs/development/UploadedFiles/IRHM73/1/Thumbnails

with 'IRHM73' being the 'username' value and '1' the 'location' value.

The problem I now have lies within this line of code:

`$absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR;`

Because the 'username' and 'location' are dynamic and hence contain different values for each user and location, I've found it impossible to find a way of creating the correct file path to open the 'Thumbnails' folder and 'files.xml'.

I had tried this:

Code: [Select]
<?php 
   
  $galleryPath = 'UploadedFiles/'; 
    
  $absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR . $usernamefolder . DIRECTORY_SEPARATOR . $locationfolder . DIRECTORY_SEPARATOR; 
  $absThumbnailsPath = $absGalleryPath . 'Thumbnails' . DIRECTORY_SEPARATOR; 
    
  $descriptions = new DOMDocument('1.0'); 
  $descriptions->load($absGalleryPath . 'files.xml'); 
?>
But I receive the following error: DOMDocument::load() domdocument.load: I/O warning : failed to load external entity /homepages/2/d333603417/htdocs/development/UploadedFiles/'files.xml'; in /homepages/2/d333603417/htdocs/development/gallery.php on line 13 and line 13 is this:  Code: [Select]
$descriptions->load($absGalleryPath . 'files.xml');

I really am stumped with what to do next to get this to work. I appreciate that this is a fairly lengthy post, but thought it would be better to post all the information.

I just wondered whether someone could perhaps take a look at this and let me know where I'm going wrong and how I can get it to work.

Many thanks and regards
