No thumbnails made by phpthumb

Yeah... you’re right.

I can use the phpThumb connector from domain A on domain B to crop a picture from domain C.

And I believe they are not being cached... can’t find the cached files.

So there is no way for creating thumbnails from a chunk or template? The GalleryTV is nice, but it would be nicer if you can specify the output of the thumbnail there and if you can link to the base image, too.
"
BTW: Why is the "gallery.phpthumb_path" linking to "...htdocs/modx/assets/components/phpthumb/" and not to the core-phpthumb-folder?

I imagine that the MiniPhoto snippet would work; all it does is get fed a URL to an image and the desired max dimensions, resize it, and return the URL of the resized version. I use it all the time in Ditto and Jot output tpls.

Needed it today and made a short snippet as a first shot. It’s derived from the phpThumb package made for Evolution (http://modxcms.com/extras/package/341). Be warned: It’s not as comfortable as with phx. Please feel free to enhance - and post it back then.

Usage:

a) Install a vanilla phpThumb (get it here: http://phpthumb.sourceforge.net/#download)
I installed it to /assets/snippets/phpThumb (path can be configured in the first line of the following snippet). Configure phpThumb with "high security" enabled, remember to set "high_security_password" too. Config file of phpThumb is "phpThumb.config.php" (has to be renamed from "phpThumb.config.php.default" first).

b) Snippet - make a new snippet in Revo and call it "snpPhpThumb".

<?php
// relative path where phpThumb is installed -
// modify this if you need to
$strPath = 'assets/snippets/phpThumb';

$strSrc = isset($image) ? $image : '';
$strOptions = isset($options) ? $options : '';

if ( !empty($strSrc) )
{
	// config file of phpThumb gets included
	require_once($modx->getOption('base_path') . $strPath . '/phpThumb.config.php');

	if(!empty($strOptions))
	{
		// options must begin with a &
		if($strOptions[0] != '&') $strOptions = '&' . $strOptions;
	}

	$strParameter = 'src=' . $strSrc . $strOptions;

	// generate hash for security
	$strHash= md5($strParameter . @$PHPTHUMB_CONFIG['high_security_password']);
	
	// append hash to query
	$strParameter .= '&hash=' . $strHash;
	
	// generate URL and return the result
	return $modx->getOption('base_url') . $strPath . '/phpThumb.php' . '?' . $strParameter;
}
else
{
	return false;
}
?>

c) Call of snippet in your resource or template, for example:

<img src="[[snpPhpThumb? &image=`/assets/images/mytestimage.jpg` &options=`w=400&h=300`]]" alt="" />

Or use a TV:

<img src="[[snpPhpThumb? &image=`[[*tvMyTestImage]]` &options=`w=400&h=300`]]" alt="" />

Every option pf phpThumb can be used, see docs or demo (http://phpthumb.sourceforge.net/demo/demo/phpThumb.demo.demo.php)

Thank you very much. That’s what I wanted.

BUT I’m getting an error!

I’ve copied all files from version 1.7.9 to assets/snippets/phpThumb_1.7.9 and modified the path in the snippet.
Calling the Image like you did, the sourcecode is also ok:

<img src="/modx/assets/snippets/phpThumb_1.7.9/phpThumb.php?src=assets/resources/images/news/P1619[01]_24-05-10kl.jpg&w=664&hash=58966a99b21a322f0ebf9c5a50592a77" title="agsrgsrgsrg" alt="agegsgafaf"/>

but the result is the error image with the message

"homepages/..../htdocs/modx/assets/snippets/phpThumb_1.7.9/assets/resources/images/news/P1619[01]_24-05-10kl.jpg" does not exist

Can you please help me?

It doesn’t work if it’s called as parameter of other snippet. Trick is to add one line before include od phpthumb config file.

	global $PHPTHUMB_CONFIG;
	require_once($modx->getOption('base_path') . $strPath . '/phpThumb.config.php');

And I believe they are not being cached... can’t find the cached files.

Shouldn’t it be protected via htaccess ?

I just made something yesterday that functions like your original request. I submitted it to the extras repository today, but I doubt it is available yet.

I have attached it to this post so you can give it a try. Let me know how it works for you!

UPDATE: Fixed package upload

Downloaded and loved it

Depending on where you are using this it could be beneficial to use & instead of & to avoid validation errors. Thank you!

Please be wary and aware that there is a major huge security hole in the phpThumb package on Sourceforge that give a great vector for script kiddies to p0wn your server. The implementation included in Revo is protected against this known vulnerability.
