所以我在wordpress主题上创建了一个复选框。所有东西都保存得很好，所有这些：
function member_page_featured_meta() {
add_meta_box( 'member_page_meta', __( 'Is this a Member Page?', 'member_page-textdomain' ), 'member_page_meta_callback', 'page', 'side', 'low' );
}
add_action( 'add_meta_boxes', 'member_page_featured_meta' );
/**
* Outputs the content of the meta box
*/
function member_page_meta_callback( $post ) {
wp_nonce_field( basename( __FILE__ ), 'member_page_nonce' );
$member_page_stored_meta = get_post_meta( $post->ID );
?>
<p>
<div class="member_page-row-content">
<label for="featured-checkbox">
<input type="checkbox" name="featured-checkbox" id="featured-checkbox" value="yes" <?php if ( isset ( $member_page_stored_meta['featured-checkbox'] ) ) checked( $member_page_stored_meta['featured-checkbox'][0], 'yes' ); ?> />
<?php _e( 'Yes', 'member_page-textdomain' )?>
</label>
</div>
</p>
<?php
}
/**
* Saves the custom meta input
*/
function member_page_meta_save( $post_id ) {
// Checks save status - overcome autosave, etc.
$is_autosave = wp_is_post_autosave( $post_id );
$is_revision = wp_is_post_revision( $post_id );
$is_valid_nonce = ( isset( $_POST[ 'member_page_nonce' ] ) && wp_verify_nonce( $_POST[ 'member_page_nonce' ], basename( __FILE__ ) ) ) ? 'true' : 'false';
// Exits script depending on save status
if ( $is_autosave || $is_revision || !$is_valid_nonce ) {
return;
}
// Checks for input and saves - save checked as yes and unchecked at no
if( isset( $_POST[ 'featured-checkbox' ] ) ) {
update_post_meta( $post_id, 'featured-checkbox', 'yes' );
} else {
update_post_meta( $post_id, 'featured-checkbox', 'no' );
}
}
add_action( 'save_post', 'member_page_meta_save' );
我需要的是制作它，这样我就可以使用Php在Wordpress中显示/隐藏内容，但我不知道如何在Php-if语句中针对它。
我是否使用名称（featured checkbox）、id（#featured check）、功能名称（$member_page_featured_meta）等
然后，为了使它成为一个特定的HTML，我想怎么做呢？
当复选框被选中时，我试图隐藏的HTML/PHP。

我会使用内联样式来隐藏和显示。你不能从PHP中瞄准HTML，所以主题方面的基本过程是：
- 决定是否应该显示
- 如果应该隐藏，请使用一个变量来存储用于隐藏节的内联CSS
- 在包含要隐藏或显示的数据的节的容器标记中输出该变量
下面是一个使用部分代码的示例：
<?php
// Retrieves the stored value from the database
$current_meta_value = get_post_meta( get_the_ID(), 'Current', true );
//Will either be empty or contain the inline CSS to hide the content.
$hideOrShow = "";
// Checks and displays the retrieved value
if( !empty( $current_meta_value ) ) {
$hideOrShow = "display: none;";
}
?>
<div id="content_to_hide_or_show" style="<?php echo $hideOrShow; ?>">
<!--Content that will be hidden or shown -->
</div>
