1.3.1 timthumb bug re-implemented?

[ningus]

Hello there,
with Bolt 1.2.1 there was a problem with thumbnails being not shown especially on 1&1 webspace. I found a solution in github here:
https://github.com/bolt/bolt/commit/089787d562e0a0a820e8c39e8874f03e320118cd

Now in 1.3.1 it is again that thumbnails being not shown like above on 1&1 webspace. It seems that while a fix is included in the new timthumb, it is still necessary to switch the order of REQUEST_URI and REDIRECT_URL to make thumbnails work.

I don't know if this a unique case....

I did recently revert these, because of this: http://stackoverflow.com/questions/6483 ... equest-uri

We had a site, where the images didn't show up in IE 8 and IE 9, because the browser didn't set the headers properly. Is it possible for you to do a var_dump for $_REQUEST for a case like this? There has to be some way to make them both work. :-/

If possible, post it here, too: https://github.com/bolt/bolt/issues/733

Bob, how do I do that? Must admit that I’m more or less a front-end dev, not sure how far I could be of help.

You mentioned a site with images not showing up in IE8-9. I just checked my site with reverted timthumb and so far no problems in IE8, wasn’t able to check IE9 though.

[ningus]

Ok, here we go. I put this

Code: Select all

{{ print(image.filename|thumbnail()) }}

...into the image loop.

And the correct paths for thumbnails show up. Like this:

Code: Select all

    … String(53) => /thumbs/240x160resize/2013-09/bandfoto-aktuell-09.jpg

    … String(53) => /thumbs/240x160resize/2013-09/bandfoto-aktuell-05.jpg

    … String(53) => /thumbs/240x160resize/2013-09/bandfoto-aktuell-06.jpg

So far, so good. With standard timthumb (bolt 1.3.1) no images are shown though. To make the thumbnails show up I need to patch the timthumb like mentioned in the first post.

[Bob]

The problem is not in the path that's generated (as shown by your example.. It's the way timthumb handles the request.

I'll see if I can tweak timthumb.php, and we'll put it through some rigorous testing to get it right once and for all..

[ningus]

Thank You!!

BTW on my local dev-machine (rather oldish Apache 2.2.15 / PHP 5.3.3) it doesn´t matter in which order REQUEST_URI and REDIRECT_URL are – or if there is only one of each declared.

From above Stackoverflow discussion it seams that REQUEST_URI is preferable, but on newer servers it may be a different story.

[Bob]

I'm still trying to figure out why it won't work on your setup.. Could you try the following?

- Make sure there is _no_ 'thumbs/' folder in the root of your site. If there is, rename or remove it temporarily.
- Verify the part for thumbnails in your .htaccess is correct. It should be:

Code: Select all

  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^thumbs/(.*)$ ./app/classes/timthumb.php [L]

- Edit the file app/classes/timthumb.php, change the start to:

Code: Select all

<?php

echo "<pre>";
print_r($_REQUEST);
print_r($_SERVER);
die();



- Then, in your browser, directly go to one of the images, like example.org/thumbs/240x160resize/2013-09/bandfoto-aktuell-05.jpg and post the output here.

This is the output. I obscured some paths in it, hope it’s still meaningful....

[Bob]

This is very helpful.. Could you try a potential fix for me?

The issue is that "REDIRECT_URL" exists, but it contains the name of the script, not the requested path to the file. It ought to be fixed for you with this additional check:

Code: Select all

if (!empty($_SERVER['REDIRECT_URL']) && (strpos($_SERVER['REDIRECT_URL'], 'timthumb.php') === false)) {
    $requesturi = $_SERVER['REDIRECT_URL'];
} else {
    $requesturi = $_SERVER['REQUEST_URI'];
}


[ningus]

This didn’t work. No thumbnails.
The $_REQUEST output looks very similar.

Code: Select all
