Ünsal Korkmaz comments:

need to go atm. will back in 10-12 hours, so i will try it when return. thx a lot for help btw :)

Dan Fraticiu comments:

I've updated the code, it will automaticly create the sw-gallery folder in the upload folder (whereever that is). I can't test it on WPMU, but I can't se why it won't work.

/home/aaa/public_html/wp-content/blogs.dir/1/files//sw-gallery/gallery-24.xml
Warning: fopen(/home/aaa/public_html/wp-content/blogs.dir/1/files//sw-gallery/gallery-24.xml) [function.fopen]: failed to open stream: No such file or directory in /home/aaa/public_html/wp-content/plugins/sw-gallery.php on line 69
Can't open file, please check you CHMOD permissions


i am getting this error :-/

Try again with the updated code. After you update the code deactivate and activate again the plugin and then checj if it creates the folder
/home/aaa/public_html/wp-content/blogs.dir/1/files//sw-gallery/

If still doesn't work, can I get an account on your blog and one for FTP, it would be easier to find the problem. In my WP install (locally) it works so it's either a peprmission problem, or something related to WP MU.

dude. i really try to find solution but creating a file seems so buggy atm.

can you make a different solution?
i can accept more query for each post.

and please try it on a wp3.0-alpha because i will make site on 3.0-alpha.

I can't think of any other way of doing this.

If you are still intrested in my idea and you can grant me some access to your ftp I'd be happy to help.

If not good luck.

After lots of try;

* sw-gallery folder creating have problem. If i create it manually, xml files creating as normal
* Try this: upload 3 photo, check xml file. There is no problem. Delete a photo then check xml file. No change, so its not removing deleted one. Delete 1 more photo too. First deleted photo data disappearing but there is still 2 photo data in xml. So basically not working for latest deleted photo

Ünsal Korkmaz comments:

and.. i found 1 more thing:
* when delete a photo, its not removing that photo data but adding
<p class="attachment"><a href='http://aaa.com/files/2010/02/bizim-006.jpg' title='bizim 006'><img width="300" height="225" src="http://aaa.com/files/2010/02/bizim-006-300x225.jpg" class="attachment-medium" alt="" title="bizim 006" /></a></p>
to other photo data's CDATA section

HI, you are write there was a problem with the deleting, because WP fired my function before any deleting was done, so the deleted attachmente still made it to the xml file.

Try this one:
<?php

add_action('add_attachment', 'generate_gallery_xml');
add_action('delete_attachment', 'generate_gallery_xml');
add_action('edit_attachment', 'generate_gallery_xml');

function generate_gallery_xml($id){
$attachment = get_post($id);

//if($attachment->post_mime_type != 'image') return; //if the attachment in not image we don't care

$args = array(
'post_type' => 'attachment',
'numberposts' => null,
'post_status' => null,
'post_parent' => $attachment->post_parent,
'post_mime_type' => 'image'
);
$attachments = get_posts($args);
if ($attachments) {

$upload_dir = wp_upload_dir();

$filename = $upload_dir['basedir'].'sw-gallery/gallery-'.$attachment->post_parent.'.xml'; //check this path

$fh = fopen($filename,'w') OR die('Can\'t open file, please check you CHMOD permissions');

$xml_content = '<?xml version="1.0" encoding="UTF-8"?>

foreach ($attachments as $a) {
if($a->ID != $id){
$image = '

';
$xml_content.=$image;
}
}

$xml_content .= '</simpleviewergallery>';

fwrite($fh, $xml_content);
fclose($fh);
}

}

register_activation_hook( __FILE__, 'sw_gallery_activate' );

function sw_gallery_activate(){
$upload_dir = wp_upload_dir();

mkdir($upload_dir['basedir'].'sw-gallery/', 0777); //check this path
}

?>

Make sure you deactive and activate the plugin to allow it to make the folder. If things don't work out, see the lines with comments after them. It seems that WP MU gets the path with an ending '/' while WP get's it without. SO if it doesn't work, try adding a '/' before "sw-gallery" in hose lines.
