是否有办法仅在特定页面模板上显示自定义页面设置？
例如，我有一个设置字段：“自定义设置”。我不想在“默认页面模板”上显示此内容。我只想在选择“自定义页面设置页面模板”时显示它。
以下是我的元框代码：
function cd_meta_box_add()
{
add_meta_box( \'icon-class-meta-box\', \'Icon Class\', \'ic_meta_box_cb\', \'page\', \'side\', \'default\' );
}
add_action( \'add_meta_boxes\', \'cd_meta_box_add\' );
function ic_meta_box_cb( $post)
{
$values = get_post_meta( $post->ID );
$selected = isset( $values[\'ic_meta_box_select\'] ) ? esc_attr( $values[\'ic_meta_box_select\'][0] ) : ”;
wp_nonce_field( \'ic_meta_box_nonce\', \'meta_box_nonce\' );
?>
<p>
<label for="ic_meta_box_select">Class</label>
<select name="ic_meta_box_select" id="ic_meta_box_select">
<option value=" " <?php selected( $selected, \' \' ); ?>> </option>
<option value="red" <?php selected( $selected, \'red\' ); ?>>red</option>
<option value="blue" <?php selected( $selected, \'blue\' ); ?>>blue</option>
<option value="green" <?php selected( $selected, \'green\' ); ?>>green</option>
<option value="pink" <?php selected( $selected, \'pink\' ); ?>>pink</option>
<option value="orange" <?php selected( $selected, \'orange\' ); ?>>orange</option>
<option value="black" <?php selected( $selected, \'black\' ); ?>>black</option>
</select>
</p>
<?php
}

我通常通过挂钩使用CSS和jQuery来实现这类功能admin_head. 这应该在客户端站点完成，因为用户可以在DOM加载后选择您的模板或另一个模板。基本上，您所要做的就是检查该值是否设置为#page_template 和切换show/hide 是否选择了模板。
add_action( \'admin_head-post.php\', \'metabox_switcher\' );
add_action( \'admin_head-post-new.php\', \'metabox_switcher\' );
function metabox_switcher( $post ){
#Isolate to your specific post type
if( $post->post_type === \'page\' ){
#Locate the ID of your metabox with Developer tools
$metabox_selector_id = \'id-of-your-metabox\';
echo \'
<style type="text/css">
/* Hide your metabox so there is no latency flash of your metabox before being hidden */
#\'.$metabox_selector_id.\'{display:none;}
</style>
<script type="text/javascript">
jQuery(document).ready(function($){
//You can find this in the value of the Page Template dropdown
var templateName = \\\'template-folder/file-name.php\\\';
//Page template in the publishing options
var currentTemplate = $(\\\'#page_template\\\');
//Identify your metabox
var metabox = $(\\\'#\'.$metabox_selector_id.\'\\\');
//On DOM ready, check if your page template is selected
if(currentTemplate.val() === templateName){
metabox.show();
}
//Bind a change event to make sure we show or hide the metabox based on user selection of a template
currentTemplate.change(function(e){
if(currentTemplate.val() === templateName){
metabox.show();
}
else{
//You should clear out all metabox values here;
metabox.hide();
}
});
});
</script>
\';
}
}

add_action(\'add_meta_boxes\', \'add_product_meta\');
function add_product_meta() {
global $post;
if(!empty($post)) {
$pageTemplate = get_post_meta($post->ID, \'_wp_page_template\', true);
if($pageTemplate == \'page-templates/product-page.php\' ) {
add_meta_box(
\'product_meta\', // $id
\'Product Information\', // $title
\'display_product_information\', // $callback
\'page\', // $page
\'normal\', // $context
\'high\'); // $priority
}
}
}
function display_product_information() {
// Add the HTML for the post meta
}
