rotate.php inside css ?
iain sherriff:
Hi.
I am going to change my theme to Crip's Anecdota. I have it working OK and have placed my banner where I want it in place of the standard logo. I changed index.css to get the banner.
With other themes I have used rotate.php to change my banners but have done it in index.template (I think!!)
I have placed a file with the images and rotate.php in "images" and changed the css to
--- Code: ---#logo a {
position: absolute;
top: 20px;
left: 20px;
display: block;
width: 512px!important;
height: 122px!important;
cursor: pointer;
background: url(../images/banners/rotate.php) no-repeat!important;
--- End code ---
If I put
--- Code: ---background: url(../images/banners/image.png)
--- End code ---
the image called for shows.
I am pretty sure I have rotate.php set right (ie, changed nothing as it is in the same folder as the images).
What I am asking is can I use rotate.php like this in css or do I need to alter index.template instead?
(would just be cleaner to use the css file)
Thanks
I asked on Crip's forum and he looked for me but is not familiar with rotate.php

What's rotate.php, exactly?

ABOUT
This PHP script will randomly select an image file from a
folder of images on your webserver. You can then link to it
as you would any standard image file and you'll see a random
image each time you reload.
When you want to add or remove images from the rotation-pool,
just add or remove them from the image rotation folder.
VERSION CHANGES
Version 1.0
- Release version
Version 1.5
- Tweaked a few boring bugs
Version 2.0
- Complete rewrite from the ground-up
- Made it clearer where to make modifications
- Made it easier to specify/change the rotation-folder
- Made it easier to specify/change supported image types
- Wrote better instructions and info (you're them reading now)
- Significant speed improvements
- More error checking
- Cleaner code (albeit more PHP-specific)
- Better/faster random number generation and file-type parsing
- Added a feature where the image to display can be specified
- Added a cool feature where, if an error occurs (such as no
images being found in the specified folder) *and* you're
lucky enough to have the GD libraries compiled into PHP on
your webserver, we generate a replacement "error image" on
the fly.
Version 2.1
- Updated a potential security flaw when value-matching
filenames
Version 2.2
- Updated a few more potential security issues
- Optimized the code a bit.
- Expanded the doc for adding new mime/image types.
Thanks to faithful ALA reader Justin Greer for
lots of good tips and solid code contribution!
INSTRUCTIONS
1. Modify the $folder setting in the configuration section below.
2. Add image types if needed (most users can ignore that part).
3. Upload this file (rotate.php) to your webserver. I recommend
uploading it to the same folder as your images.
4. Link to the file as you would any normal image file, like this:
<img src="http://example.com/rotate.php">
5. You can also specify the image to display like this:
<img src="http://example.com/rotate.php?img=gorilla.jpg">
This would specify that an image named "gorilla.jpg" located
in the image-rotation folder should be displayed.
That's it, you're done.
*/
/* ------------------------- CONFIGURATION -----------------------
Set $folder to the full path to the location of your images.
For example: $folder = '/user/me/example.com/images/';
If the rotate.php file will be in the same folder as your
images then you should leave it set to $folder = '.';
*/
$folder = '.';
/*
Most users can safely ignore this part. If you're a programmer,
keep reading, if not, you're done. Go get some coffee.
If you'd like to enable additional image types other than
gif, jpg, and png, add a duplicate line to the section below
for the new image type.
Add the new file-type, single-quoted, inside brackets.
Add the mime-type to be sent to the browser, also single-quoted,
after the equal sign.
For example:
PDF Files:
$extList['pdf'] = 'application/pdf';
CSS Files:
$extList['css'] = 'text/css';
You can even serve up random HTML files:
$extList['html'] = 'text/html';
$extList['htm'] = 'text/html';
Just be sure your mime-type definition is correct!
*/
$extList = array();
$extList['gif'] = 'image/gif';
$extList['jpg'] = 'image/jpeg';
$extList['jpeg'] = 'image/jpeg';
$extList['png'] = 'image/png';
// You don't need to edit anything after this point.
// --------------------- END CONFIGURATION -----------------------
$img = null;
if (substr($folder,-1) != '/') {
$folder = $folder.'/';
}
if (isset($_GET['img'])) {
$imageInfo = pathinfo($_GET['img']);
if (
isset( $extList[ strtolower( $imageInfo['extension'] ) ] ) &&
file_exists( $folder.$imageInfo['basename'] )
) {
$img = $folder.$imageInfo['basename'];
}
} else {
$fileList = array();
$handle = opendir($folder);
while ( false !== ( $file = readdir($handle) ) ) {
$file_info = pathinfo($file);
if (
isset( $extList[ strtolower( $file_info['extension'] ) ] )
) {
$fileList[] = $file;
}
}
closedir($handle);
if (count($fileList) > 0) {
$imageNumber = time() % count($fileList);
$img = $folder.$fileList[$imageNumber];
}
}
if ($img!=null) {
$imageInfo = pathinfo($img);
$contentType = 'Content-type: '.$extList[ $imageInfo['extension'] ];
header ($contentType);
readfile($img);
} else {
if ( function_exists('imagecreate') ) {
header ("Content-type: image/png");
$im = @imagecreate (100, 100)
or die ("Cannot initialize new GD image stream");
$background_color = imagecolorallocate ($im, 255, 255, 255);
$text_color = imagecolorallocate ($im, 0,0,0);
imagestring ($im, 2, 5, 5, "IMAGE ERROR", $text_color);
imagepng ($im);
imagedestroy($im);
}
}
?>

Arantor:
You can use rotate.php in CSS just fine, provided that you can see images when you browse directly to rotate.php.
iain sherriff:
thanks........I cant so that's what I need to check. I can go direct to an image so the path is correct, it must be something in the rotate.php file ?
hmmm
