I am trying to set up phpThumb to generate thumbnails for me as seen
in: http://bakery.cakephp.org/articles/view/thumbnails-generation-with-phpthumb
I set everything up just as the article says, the only modification I
have made was to the line:
$sourceFilename = WWW_ROOT.$_GET['src'];
changed to:
$sourceFilename = WWW_ROOT.DS.'img'.$_GET['src'];
AND
vendor("phpthumb".DS."phpthumb.class");
changed to:
App::import('vendor', "phpthumb".DS."phpthumb.class");
The line with 'vendor()' gave me an error say it was an unknown
function.
Now the error I get is a Fatal error saying it cannot locate the
phpThumb() class and I am not sure why, it seems the vendor file
should loaded properly and it should see it...
Below is the entire ThumbsController
<?php
class ThumbsController extends AppController
{
var $name = 'Thumbs';
var $uses = null;
var $layout = null;
var $autoRender = false;
function index()
{
if(empty($_GET['src'])){
die("No source image");
}
//width
$width = (!isset($_GET['w'])) ? 100 : $_GET['w'];
//height
$height = (!isset($_GET['h'])) ? 150 : $_GET['h'];
//quality
$quality = (!isset($_GET['q'])) ? 75 : $_GET['q'];
$sourceFilename = WWW_ROOT.DS.'img'.$_GET['src'];
if(is_readable($sourceFilename)){
App::import('vendor',
"phpthumb".DS."phpthumb.class");
$phpThumb = new phpThumb();
$phpThumb->src = $sourceFilename;
$phpThumb->w = $width;
$phpThumb->h = $height;
$phpThumb->q = $quality;
$phpThumb->config_imagemagick_path = '/usr/bin/
convert';
$phpThumb->config_prefer_imagemagick = true;
$phpThumb->config_output_format = 'jpg';
$phpThumb->config_error_die_on_error = true;
$phpThumb->config_document_root = '';
$phpThumb->config_temp_directory = APP . 'tmp';
$phpThumb->config_cache_directory =
CACHE.'thumbs'.DS;
$phpThumb->config_cache_disable_warning = true;
$cacheFilename = md5($_SERVER['REQUEST_URI']);
$phpThumb->cache_filename = $phpThumb-
>config_cache_directory.$cacheFilename;
//Thanks to Kim Biesbjerg for his fix about cached
thumbnails being regeneratd
if(!is_file($phpThumb->cache_filename)){ // Check if
image is already cached.
if ($phpThumb->GenerateThumbnail()) {
$phpThumb->RenderToFile($phpThumb-
>cache_filename);
} else {
die('Failed: '.$phpThumb->error);
}
}
if(is_file($phpThumb->cache_filename)){ // If thumb was
already generated we want to use cached version
$cachedImage = getimagesize($phpThumb-
>cache_filename);
header('Content-Type: '.$cachedImage['mime']);
readfile($phpThumb->cache_filename);
exit;
}
} else { // Can't read source
die("Couldn't read source image ".$sourceFilename);
}
}
}
?>
