Description (last modified by scribu)

Currently, we have filters for each template type: home_template, author_template etc.

The trouble is that these filters are applied on the final template path, after the template hierarchy has been traversed.

It would be useful if there was another filter applied to the actual template hierarchy array, before it was sent to locate_template().


Take the author template hierarchy:

author-{nicename}.php > author-{id}.php > author.php

Say I want to add author-{role}.php before author.php.

Sure, I could use the 'author_template' filter:

function author_role_template( $old_template ) {
  // get current author's role

  $new_template = locate_template( array( "author-$role.php" ) );

  if( $new_template && 'author.php' == $old_template )
    return $new_template;

  return $old_template;
add_filter('author_template', 'author_role_template');

With an 'author_template_candidates' hook, I could manipulate the actual hierarchy:

function author_role_template( $templates ) {
  // get current author's role

  $new_template = array( "author-$role.php" );

  $templates = array_merge( 
    array_slice( $templates, 0, -1 ), // before
    $new_template,                    // inserted
    array_slice( $templates, -1 )     // after

  return $templates;
add_filter('author_template_hierarchy', 'author_role_template');

This would allow me to remove author-{id}.php if I wanted, etc.

template_candidates.diff makes all get_*_template() functions call get_query_template(), which consistently applies the appropriate filters.

template_hierarchy.diff just renames the filter *_template_hierarchy, which seems more appropriate.
