We have one post after another flipping stuff around and it's getting a little confusing.  I understand this is how things improve through community participation but I'm not sure which posters found a working solution as some people are updating pieces of other's work.

I was wondering if someone can post a verified final working version of this all in one place.

I've tried every rotate.php script version in this thread and none of them are working for me.

Depending on the version of rotate.php I get one of two things...

1.  White screen and nothing else happens.

or

2.  Internal Server Error.


I'm using 4images 1.7.2

I'm only interested in the admin having this new function.  So I added the rotate.php to the includes directory.  I added the rotate text to my language file.  Then I changed the details.php so that there are links for the admin to rotate on the details page. (the links are displaying fine.)

That's all I did.  Did I miss something or do I need to find the correct "rotate.php" version or combination of pieces of these rotate.php versions?

When an Image is uploaded, you get a page with te result, is it possible to add the rotate option to that page?

Even though I found a major problem with your code, I still can't get it to work. Exclamation

Arrow In your rotate.php you are looking for variable wize to be "pos"...

[qcode]//clockwise or anticlockwise?
$degrees=0;
if ($wize=="neg"){$degrees = 90;}
if ($wize=="180"){$degrees = 180;}
if ($wize=="pos"){$degrees = 270;}
[/qcode]

Arrow But your new admin links are passing variable wize as "270"...

[qcode]$admin_links .= "<a href=\"".$site_sess->url(ROOT_PATH."includes/rotate.php?".URL_IMAGE_ID."=".$image_id."&amp;wize=270")."\">".$lang['rotate_pos']."</a>";[/qcode]

Hi,

i have the same problem.
The button for "rotate" is still there but the code does not rotate the image. After the operation as "root" i am in the index.php.

Can someone help me?

I'm looking for a script that rotates an image like the one in the first post!

My version is the latest 1.7.10... Is there a chance to get it work?

How can i do this with V1.8?
Is there a ready made mod/plug in?
Will the solution given in this thread work with 1.8?
