Error in Custom Taxonomy UI

Question

Hi I'm running a site that makes heavy use of a custom taxonomy called 'Games' and using the Simple Term Meta plugin the metadata for these terms. Using pretty much a copy of the code from wordheavy.com it's working fine except for two things: it throws an error on the 'Game' taxonomy page (Warning: Missing argument 2 for game_form_fields() in ommitted/functions.php on line 32) and when you add a 'game' the form doesn't clear.

You can find a copy of my code here.

I'm not quite where to start (apart from line 32!) so any direction would be appreciated.

Answer 1

The issue at first glance appears to be here..

add_action('game_edit_form_fields', 'game_form_fields');
add_action('game_add_form_fields', 'game_form_fields');
function game_form_fields($tag,$taxonomy) {

Your function is expecting 2 vars to be passed from the hook, but your add_action calls default to 1..

Eg, this..

add_action('game_edit_form_fields', 'game_form_fields');

Is equal to this..

add_action('game_edit_form_fields', 'game_form_fields', 10, 1 );

The fourth parameters sets how many arguments your callback function can take, and the default is 1, so that's all your function ever receieves. Updating those add_action calls to the following should fix it..

add_action('game_edit_form_fields', 'game_form_fields', 10, 2 );

Hope that helps..

Maybe the hook isn't passing a second variable, instead of the previous change, try update the function line to read..

function game_form_fields( $tag ) {

Perhaps that will fix it..
