Unsupported post formats still visible

[ericmann]

Using the latest build (3.1 RC2), ff you add theme support for an unknown post-format it appears on the edit screen, but with a blank label.

Test with the following:

add_theme_support( 'post-formats', array( 'aside', 'gallery','bug' ) );

You will see 4 radio buttons and 3 visible labels: Standard, Aside, Gallery. The 4th label markup is there, but with no visible text.

Check to make sure the post format string exists ( != ) before adding its markup to the UI.

Tested and seems to work, but should this be 'patched' or should a check_post_formats function be created now for future usage.

Maybe we can remove these at the add_theme_support level by doing a diff with get_post_format_slugs.

probably need to do something, the diff isn't taking into account options-writing.php which has a selection for the default post-format.

Suggestion then. in theme.php change the function add_theme_support to this:

function add_theme_support( $feature ) {
	global $_wp_theme_features;

	if ( func_num_args() == 1 )
		$_wp_theme_features[$feature] = true;
	else
		$_wp_theme_features[$feature] = array_slice( func_get_args(), 1 );
	
	if ( $feature == 'post-formats' ) 
		$_wp_theme_features[$feature] = check_post_format_support($_wp_theme_features[$feature]);

}

and add this function to that file:

function check_post_format_support( $theme_post_formats ) {
	$allowed_post_formats = array_keys(get_post_format_strings());
	$checked_post_formats =  array();
	foreach ( $theme_post_formats[0] as $check_format ) {
		if ( in_array ( $check_format, $allowed_post_formats ) ) {
			$checked_post_formats[] = $check_format;
		}
	}
	$return_post_formats[0]=$checked_post_formats;
	return $return_post_formats;
}

Although there is almost certainly an easier way of doing it.

Done.

Yeah much neater.

Replying to elfin:

Yeah much neater.

Agreed.

Tested the patch and it works nicely, both in the situation previously explained in the ticket and on options-writing.php (as mentioned by @elfin in comment 3).

use array_intersect() instead of foreach

forgot to check is_array()

final patch, fixed internationalization issue in 16073.3.patch

(In [17213]) Ignore unsupported post types in add_theme_support(). Props garyc40. fixes #16073
