Topic: HTML in categoriy image field?

[Tiribulus]

Does the image field for categories support anything beyond simple url's? Not that I'm bummed if it doesn't but I was trying to figure out a simple way to have the images rotate.
Thanks

Normal it should not work.

If that's the case, you could create a .php script as the image and link to it.

Open your FTP client, make a new folder named "rotate_images" and place all the images you want to rotate between in there, numbered (such as 1.png, 2.png, 3.png) and ensure they're of the .png extension (all lower-cased).

Then make a file named image.php, and put:

Code: [Select]

<?php
// Rotate between the images.

// Make sure to have a slash at the end.
$path = 'this/is/the/local/path/to/the/rotate_images/directory/';

@header('Content-type: image/png');
@header('Cache-Control: no-cache, must-revalidate');
@header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");

// Replace the # with the number of images you have in the directory.
$number = mt_rand(1, #);

// Creating the image path...
$image = $path . '/' . $num . '.png';

// Generating the image.
@readfile($image);

?>

Thank you so much guys. I will try that as soon as I get a chance and let you know how it goes.

Will it work with gifs if I change the instances of png in your code to gif. Or maybe I could just change the extension of the gif files to .png.

Here;

Code: [Select]

<?php
// Rotate between the images.

// Make sure to have a slash at the end.
$path = 'this/is/the/local/path/to/the/rotate_images/directory/';

// The format of the images
$format = 'png';

@header('Content-type: image/' . $format);
@header('Cache-Control: no-cache, must-revalidate');
@header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");

// Replace the # with the number of images you have in the directory.
$number = mt_rand(1, #);

// Creating the image path...
$image = $path . '/' . $num . '.' . $format;

// Generating the image.
@readfile($image);

?>

Don't ask me what I'm doin wrong here.

I created a folder in the docroot named rotate_images .

Created a file name image.php with this code:

Code: [Select]

<?php
// Rotate between the images.

// Make sure to have a slash at the end.
$path = '/srv/www/htdocs/rotate_images/';

// The format of the images
$format = 'png';

@header('Content-type: image/' . $format);
@header('Cache-Control: no-cache, must-revalidate');
@header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");

// Replace the # with the number of images you have in the directory.
$number = mt_rand(1, 4);

// Creating the image path...
$image = $path . '/' . $num . '.' . $format;

// Generating the image.
@readfile($image);

?>
and put it in that rotate_images directory.

I put 4 gif files named 1.gif, 2.gif, 3.gif and 4.gif in there as well.

This might be where I'm missing it. I tried linking it with http://localhost/rotate_images/image.php, http://localhost:8080/rotate_images/image.php, and http://gregnmary.gotdns.com:8080/rotate_images/image.php and it doesn't want to display the images.

Try changing this:

Code: [Select]

$format = 'png';
To this:

Code: [Select]

$format = 'gif';

[Tiribulus]

I actually did try that and forgot to mention it last night. I did again just now and it still doesn't want to do it.
Thanks for the response though.

If it's any clue, it doesn't work when I try to run the file directly in a browser either.

[ccbtimewiz]

Show me what you put, and link me to it.

[Tiribulus]

Code: [Select]

<?php
// Rotate between the images.

// Make sure to have a slash at the end.
$path = '/srv/www/htdocs/rotate_images/';

// The format of the images
$format = 'gif';

@header('Content-type: image/' . $format);
@header('Cache-Control: no-cache, must-revalidate');
@header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");

// Replace the # with the number of images you have in the directory.
$number = mt_rand(1, 4);

// Creating the image path...
$image = $path . '/' . $num . '.' . $format;

// Generating the image.
@readfile($image);

?>
That is the present code in the image.php file which is here:

http://gregnmary.gotdns.com:8080/rotate_images/image.php

If that's what you mean. This is no pressing thing for me BTW, It was just something I got a bug in my butt about because I couldn't figure it out myself having a grand total of about 2 months coding experience.
Thanks again

Hm, it appears to be loading and not loading.

It is perhaps a link problem. Are you sure that is the path to the correct folder? There is no 'home' in the URL?

Perhaps try making the path just /rotate_images/

Change your images.php script codes with these ones:

Code: [Select]

<?php
header('Content-Type: image/gif');
@readfile(mt_rand(1, 4) . '.gif');
?>

This is really a great tweak. It took me a about a minute to adapt it to a second forum.  I think some other people may like this as well
