模板覆盖使用自定义部分

Question

我试图从自定义部分覆盖我的默认模板,我使用代码来做到这一点,但如果我使用它我无法将模板分配给编辑页面页面,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.有一个特殊的条件,我想让它工作.

 <?php
    /**
     * Adds the Customize page to Select template For Pages
     */

    add_action( 'wp_footer', 'cur_page_template' );
function cur_page_template(){
    var_dump( get_option('current_page_template') );
    var_dump( get_page_template() );
    exit;
}
 function widgetsite_template_override($wp_customize){
    $wp_customize->add_panel( 'template_options', array(
        'title' => __( 'Template Options', 'widgetsite' ),
        'description' => $description, // Include html tags such as <p>.
        'priority' => 160, // Mixed with top-level-section hierarchy.
    ) );

    $wp_customize->add_section('theme_template_override', array(
        'title'    => __('Override  Templates', 'widgetsite'),
        'panel' => 'template_options',

Answer 1

1. 如何从后期编辑屏幕中选择模板框.

重要的是要记住页面也是帖子,并且与帖子相关的所有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wp_postmeta使用键来保存数据库表中的模板文件路径_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,但你提到你想要理解这个过程,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.

2. 过滤器template_include在搜索页面类型的正确模板的函数内(其他帖子类型具有过滤器single_template)

您在此处使用包含不正确.在这种情况下,不要忘记过滤器会期望返回的值正常工作$template.

所以,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;
}

3. 设置选择

您缺少默认值,所以我建议使用以下mod,因为我无法看到您的设置,get_option('current_page_template')但如果有正确的文件名,则替换page.php它.

虽然您没有为选择框设置默认值,但如果没有标记为选中框,则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)
 ));

如果您重新保存上面的所有选项,它应该正常工作(这对我来说)!
