I am working on editing the Geotag Plugin to make it compatible with WPMU. I have registered the settings and adding the settings_fields function but everytime I click "Save Settings" I get a message that says "Settings Saved" and all of the fields have gone back to default. Basically, it is not actually saving the settings. This is a large php file so posting the whole thing is a little bit of an overkill. Let me know what it is you need to see to help out.
Thanks.
To add a little more information it looks like this plugin isn't creating any entries in the DB
So there is no update_option('Option Name',option_array); call?
There is not. I'm going to paste a little of the code in. It's all handled in one file so I'm leaving out a lot of the actual plugin functionality code

}The form posts to options.php and uses that to save its settings.
This is how I did it in my plugin:
Set up defaults:
// Get the current settings or setup some defaults if needed
if (!$current_settings = get_option('lastfm_options')){
$lastfm_options['lastfm_user'] = 'YourNameHere';
$lastfm_options['lastfm_colour'] = 'grey';
$lastfm_options['lastfm_size'] = '405';
$lastfm_options['lastfm_artist'] = 'Artist Name Here';
$lastfm_options['lastfm_genre'] = 'Genre Here';
$lastfm_options['lastfm_friends'] = 'No';
update_option('lastfm_options', $lastfm_options);
}Form definition starts :
<form method="post" action="options-general.php?page=lastfm.php">
<input type="hidden" name="action" value="save_options" />
<fieldset class="options">Then right at the bottom I have:
add_action('widgets_init', 'widget_lastfm_init');
add_action('admin_menu', 'lastfm_add_options'); // Insert the Admin panel.
if ($_POST['action'] == 'save_options'){
lastfm_save_options();
}
?>with lastm_save_options() defined as:
function lastfm_save_options() {
$lastfm_options['lastfm_user'] = $_POST['lastfm_user'];
$lastfm_options['lastfm_colour'] = $_POST['lastfm_colour'];
$lastfm_options['lastfm_size'] = $_POST['lastfm_size'];
$lastfm_options['lastfm_artist'] = $_POST['lastfm_artist'];
$lastfm_options['lastfm_genre'] = $_POST['lastfm_genre'];
$lastfm_options['lastfm_friends'] = $_POST['lastfm_friends'];
update_option('lastfm_options', $lastfm_options);
}I basically based that on someone else's code and it works for WP and WPMU. Its probably "wrong" or inefficient but it works.
BTW - if you go to http://bobsp.de/weblog/geotag/
there is a comment:
"Hi,
as reported by holyolli, running the Geotag plugin with Wordpress MU will produce some trouble. I tried to find out what went wrong and noticed, that only the procedure which saves the options is affected. Although I stick to the Wordpress Codex for creating options pages, you will always receive a failure notice if you try to save the options. To be honest, right now I don’t now how I can improve the plugin to avoid this error, but I compared the Worpdress MU with the standard version and found the difference which causes the trouble.
Take a look at the /wp-admin/options.php file and search for the following code:
case ‘update’:
if ( isset($_POST[ 'option_page' ]) ) {
$option_page = $_POST[ 'option_page' ];
check_admin_referer( $option_page . ‘-options’ );
}
…
If you change this to
case ‘update’:
if ( isset($_POST[ 'option_page' ]) ) {
$option_page = $_POST[ 'option_page' ];
check_admin_referer( $option_page . ‘-options’ );
} else {
// This is for back compat and will eventually be removed.
$option_page = ‘options’;
check_admin_referer( ‘update-options’ );
}!
I'll give it a go and see what happens. Thanks
I tried to run that hack with no results so I'm working on getting this thing to operate natively with MU. I think there is enough of a demand that this would be a welcome patch
Well it looks quite interesting
I think there is some conflicting logic going on. I implemented the things you had and am now getting a blank page when update. Back to the drawing board.
blank page... hmm whats in the error logs ;-)
Don't know yet. Just sent down to the network team to check. I've gotten it to write the settings tables to options.php but am unable to save to those tables right now. Basically, I have all of the settings in the table but they remain unupdated.
ok, here are the php logs
"script '/www/blog/current/wp-admin/general-options.php' not found or unable to stat, referer: http://blog.newsok.com/dustyglobe/wp-admin/options-general.php?page=geotag%2Fgeotag.php&updated=true
That's all that was going on when the blank page showed.
More news. It looks like the the options entries exist for the blog the plugin is activated on. But I still can't update the fields via the options page for the plugin.
Hey nicktank,
basically it is possible to save the options "manually" like SteveAtty described. However, I tried to go the way described in the Wordpress Codex. It seemed to me more elegant as all the handling is done by Wordpress. Unfortunately this solution does not work with Wordpress MU and I am not sure why. You already discovered the workaround I posted on my weblog which worked on my testing system.
Perhaps it is possible to bring this question to one of the developers. Otherwise I already considered to do the saving of the options manually. This is less elegant but at least it should work with all Worpress versions. Anyway, if you found any other solution I would be glad to hear about it so that I can integrate it in the next version.
Thanks for your efforts so far!
Cheers
Boris
