我正在尝试从自定义部分覆盖我的默认模板，我正在使用代码来执行此操作，但如果我使用它，我无法将模板分配到编辑页面页面，任何人都可以知道如何自定义部分和编辑页面分配模板工作。我想在创建页面时设置模板，在分配之后我想覆盖它。 考虑我有一个博客页面，我想分配它archive.php模板，十个想要从自定义部分覆盖它。我希望它有特殊的条件。

答案 0 :(得分：5)
重要的是要记住页面也是帖子，所有与帖子相关的元数据都存储在帖子元表中。页面帖子类型与标准帖子类型略有不同，因为它们不遵循single-postname.php模板使用功能。相反，页面将模板文件路径保存在wp_postmeta数据库表中，密钥为_wp_page_template。
因此，更改此值的一个选项是在保存帖子后更改它。
function save_template_file( $post_id ) {
if ( 'page' != $post->post_type ) {
return;
}
//insert logic here
$filelocation= 'anywhere.....';
update_post_meta($post_id, '_wp_page_template', $filelocation);
}
add_action('save_post', 'save_template_file', 11 );
现在这不是你想要的，但是你提到你想要了解这个过程，所以对于页面，wp将从post meta引用模板文件并拉出这个值。因此，如果它始终遵循相同的逻辑（稍微优化过程），您可以在保存后更改它。这是在编辑帖子屏幕中显示的文件，并且将始终拉取db值，除非wp尝试加载模板并意识到它不再存在，在这种情况下它将恢复到选择框中的默认文件。
template_include位于搜索网页类型的正确模板的函数内（其他帖子类型包含过滤器single_template）您在此处使用包含不正确。不要忘记过滤器会期望返回的值在这种情况下$template正常工作。
因此，如果我们想要更改页面的模板....
add_filter('template_include', 'assign_new_template');
function assign_new_template ($template){
//we already have a template name, no need to pull it again..
$cur= basename($template);
if( $cur === 'page.php' && get_theme_mod("widgetsite_page_template")){ //note $cur will never be empty!
$template= get_template_directory() . '/layouts/' . get_theme_mod("widgetsite_page_template");// assuming this will return correct template...
//if issues try hardcoding a path to test...
}
// dont need a else, we will only change the template if our logic is satisfied...
// etc
return $template;
}
你缺少默认值，所以我建议使用以下mod，因为我无法看到你在get_option('current_page_template')中的设置，但是如果有正确的文件名则用它替换page.php。
虽然您没有为选择框设置默认值，但如果没有选择任何标记，则您的页面将呈现选择的第一个值，因此它应该相同。
$wp_customize->add_control( 'widgetsite_search_template', array(
'settings' => 'widgetsite_search_template',
'label' => 'Override Search Template:',
'section' => 'theme_template_override',
'type' => 'select',
'choices' => array_merge(array("page.php"=>'default'), $cats)
));
如果您重新保存上述所有选项，它应该正常工作（这对我而言）！
