Capabilities for custom taxonomies

    Heya!

    I’ve been using this plugin happily for some time now but found only recently the need to give custom user roles the rights to assign terms from custom taxonomies.

    I tried to fiddle around with the ‘cptui_pre_register_taxonomy’ filter hook but only broke just about everything I could while trying (fixed it again but leaving the hook alone ?? so no problem there)

    but the only solution I finally found was directly editing the plugin files. As that means I will lose my functionality everytime the plugin updates, I thought I’d throw my solution in here and hope it (or something similar) might maybe get into the original code.

    So what I did was:

    I added ‘capabilities’ to the register_taxonomy $args variable in custom-post-type-ui.php (line 279):

    $args = array(
		'labels'            => $labels,
		'label'             => $taxonomy['label'],
		'hierarchical'      => get_disp_boolean( $taxonomy['hierarchical'] ),
		'show_ui'           => get_disp_boolean( $taxonomy['show_ui'] ),
		'query_var'         => $taxonomy['query_var'],
		'rewrite'           => $rewrite,
		'show_admin_column' => $show_admin_column,
		'capabilities' => array(
               'edit_terms' => 'edit_' . $taxonomy['name'],
               'delete_terms' => 'delete_' . $taxonomy['name'],
               'assign_terms' => 'assign_' . $taxonomy['name'],
               )
          );

    Now all my custom taxonomies can still managed by the administrator, but I can assign edit, delete and assign rights to (custom) user roles.

    If that functionality is un-needed but the plugin, I’ll just copy my bit of code back into it after every update, no worries ??

    Thanks again for a great plugin!

    Custom capability settings are something that hasn’t properly been introduced into the plugin, to be honest. Not sure quite what I want to do there because it does get into a complex area of post types/taxonomies that most people don’t need to worry about.

    You should have been able to add the bits to the args via the cptui_pre_register_taxonomy hook though.

    Just use something like this:

    function gaseous_taxonomy_caps( $args, $taxonomy ) {
	$args['capabilities'] = array(
		'edit_terms'   => 'edit_' . $taxonomy['name'],
		'delete_terms' => 'delete_' . $taxonomy['name'],
		'assign_terms' => 'assign_' . $taxonomy['name'],
	);

	return $args;
}
add_filter( 'cptui_pre_register_taxonomy', 'gaseous_taxonomy_caps', 10, 2 );

    I tried that. (and will happily try your code again as I am much happier with a hooked solution) but for some odd reason it broke stuff.

    I will test and debug it once more as soon as I find the time (should be sometime this week)

    Another question to the topic:

    what would I hook for only one taxomony? say on called ‘countries’? where can I tell the hook which taxonomy I’d like to change?

    thanks a lot for the quick answer.

    I’d wrap the $args[‘capabilities’] assignment with a check of the taxonomy passed in via $taxonomy, and only add the array index if it matches ‘countries’. You’ll still want to return $args at the end regardless, but that’d change it conditionally.

    I wager you may need to re-work exactly what all you need for the capabilities. I’ve never done much with this, so I don’t have definitive answers. I think it’s a case of you need to manually set every capability they should have, instead of just providing the ones you want added/removed/changed and WordPress core fills in the rest.
