[PATCH] Lots of errors in WP3.6

After upgrading to WP3.6 I’m getting a bunch of errors like:

Strict standards: Declaration of AVH_Walker_Category_Checklist::start_lvl() should be compatible with Walker::start_lvl(&$output, $depth = 0, $args = Array) in /extended-categories-widget/3.3/class/avh-ec.widgets.php on line 1003

this is caused by you not implimenting the functions in the same way the Walker class impliments them – ie no default values.

In /extended-categories-widget/3.3/class/avh-ec.widgets.php and /extended-categories-widget/3.3/class/avh-ec.core.php
change

function start_lvl (&$output, $depth, $args)
function end_lvl (&$output, $depth, $args)
function start_el (&$output, $category, $depth, $args)
function end_el (&$output, $category, $depth, $args)

to

function start_lvl( &$output, $depth = 0, $args = array() )
function end_lvl( &$output, $depth = 0, $args = array() )
function start_el( &$output, $object, $depth = 0, $args = array(), $current_object_id = 0 )
function end_el( &$output, $object, $depth = 0, $args = array() )
function walk( $elements, $max_depth)

You have a third argument ($args) for your walk method that doesn’t exist in the Walker class. I’m not sure how you’d fix this other than to rename your walk method to avh_walk() then update your references in avh_wp_category_checklist() and avh_wp_group_category_checklist() methods.

Next up is

Strict standards: Non-static method AVH_EC_Singleton::getInstance() should not be called statically, assuming $this from incompatible context in /path/to/plugins/extended-categories-widget/3.3/class/avh-ec.admin.php on line 28

In /extended-categories-widget/3.3/avh-ec.client.php change

function &getInstance ($class, $arg1 = null)

to

public static function &getInstance ($class, $arg1 = null)

And finally

Strict standards: Redefining already defined constructor for class AVH_EC_Category_Group in /extended-categories-widget/3.3/class/avh-ec.category-group.php on line 36

Just remove the PHP5 constructor and dump all the code in your PHP4 constructor. Should remove this warning.
