snark – You don’t need to hack the core files. (Though, admittedly, this would be a lot easier if the tag cloud were filterable before it was converted into HTML. The method I used is clunky at best.) The following two functions in functions.php should rearrange all tag clouds to be in alphabetical order:

function bbg_compare_alphabetical($a, $b) {

return strCmp($a['name'], $b['name']);

}



function bbg_alphabetical_tag_cloud_filter( $a, $b ) {

$tags = explode( "\\n", $a );

$tags_new = array();

foreach( $tags as $key => $tag ) {

$tag_split = explode( '</a>', $tag );

$cut = strrpos( $tag_split[0], '>' );

$tag_name = substr( $tag_split[0], $cut + 1 );

$tag_new = array( 'name' => $tag_name, 'html' => $tag );

$tags_new[] = $tag_new;

}



usort( $tags_new, "bbg_compare_alphabetical" );



$tags_sorted = array();

foreach( $tags_new as $tag ) {

$tags_sorted[] = $tag['html'];

}

$tags_sorted = implode( "\\n", $tags_sorted );



return $tags_sorted;

}

add_filter( 'tag_heat_map', 'bbg_alphabetical_tag_cloud_filter', 10, 1 );
