I'm trying to be a good thememaker and pass all my settings through the Settings API, but I'm running into some difficulty in the sanitization callback function.

The core of the problem is this: the $input variable, passed in by default, is empty. My $_POST[options group] is coming through just fine (it has everything I'd expect to see in $input) but, again, $input is empty. Where do I even start looking to debug this?

EDIT 1

In response to Chip, here's what I have (stubbed, obviously):

function lblg_sanitize_options( $input ){
global $lblg_shortname, $lblg_default_options;

echo "Input: ";
print_r($input);

If I do something similar using, e.g., Oenology and do a print_r($input);, I get the expected Array( etc.

EDIT 2

Here's the results of print_r($_REQUEST); for my theme:

Array ( [option_page] => lblg_options [action] => update [_wpnonce] => 1f96eb2410 [_wp_http_referer] => /wp-admin/themes.php?page=lblg_options [lblg_options] => Array ( [layout_stylesheet] => Select a layout: [alt_stylesheet] => *none* [use_custom_header] => true [display_footer_copyright] => true [footer_copyright] => [footer_credit_text] => [save] => Save changes ) )

And here it is for Oenology:

Array ( [option_page] => theme_oenology_options [action] => update [_wpnonce] => 748c46a1a1 [_wp_http_referer] => /wp-admin/themes.php?page=oenology-settings [theme_oenology_options] => Array ( [header_nav_menu_position] => below [header_nav_menu_depth] => 1 [display_social_icons] => on [rss_feed] => rss2 [facebook_profile] => [flickr_profile] => [linkedin_profile] => [myspace_profile] => [twitter_profile] => [youtube_profile] => [display_footer_credit] => false [submit-general] => Save Settings ) )

I can't spot the difference. Can you?

EDIT 3

Might the various slugs/shortnames/pagenames be conflicting somehow?

EDIT 4

Here's what I'm doing for registration:

function lblg_admin_init(){
    global $lblg_shortname;
    register_setting( 'lblg_options', $lblg_shortname . '_lblg_options', 'lblg_sanitize_options' );
}

Here's what I'm calling out, intra-options-form:

settings_fields( 'lblg_options' ); 
do_settings_sections( 'lblg_options' );

The settings themselves are all being registered in a big loop, in a fashion similar to this:

add_settings_field( $key, $value['name'], '', 'lblg_options', $section );

Further thoughts?

Can you post (pastebin, etc.) your entire options code? Trying to piecemeal this might not be effective. –  Chip Bennett May 12 '11 at 15:59
    
Chip: the code is lousy with debug messages, so it won't work at the moment, but here's an intermediate Hg format. bitbucket.org/zamoose/lblg/src/60ba9a5d09c9/functions.php bitbucket.org/zamoose/lblg/src/60ba9a5d09c9/includes/functions/… and bitbucket.org/zamoose/lblg/src/60ba9a5d09c9/includes/functions/… –  ZaMoose May 12 '11 at 17:17

The $input variable is not passed to the validate function by default. You need to declare it, e.g. not this:

function mytheme_validate_settings() {}

But rather, this:

function mytheme_validate_settings( $input ) {}

(Or maybe I'm the only one who's made that bone-headed mistake before?) :)

EDIT:

The other thing to check: does the $optiongroup in register_setting() match the argument passed to settings_fields() in your form markup?

No, I've got that. I'm actually taking a page from your Oenology setup, it's just not working. –  ZaMoose May 12 '11 at 13:29
    
Next thing to check: $optiongroup. See edit. –  Chip Bennett May 12 '11 at 13:42
    
Check the edits above. –  ZaMoose May 12 '11 at 15:35
    
Where is the $optiongroup passed into add_settings_field()? –  Felix Eve May 15 at 10:29
    
Arr, I see, it has to match the variable passed into settings_fields(), not add_settings_field(). –  Felix Eve May 15 at 20:46

Answering my own question by way of an answer Chip has embedded in his excellent settings tutorial, namely: it's all about Correlating Function Arguments. Apparently some of the variable names/options group names I was using weren't lining up correctly.

That's the trickiest part sometimes, isn't it? –  Chip Bennett May 20 '11 at 23:42
