どのように私はWYSIWYGエディタの下に "投稿オプション"セクションを追加することができますか? このように
あなたは add_meta_box
関数を使わなければなりません。
このチュートリアルを見てください。
以下のコードを試してみてください。
/* Define the custom box */
// WP 3.0+
add_action( 'add_meta_boxes', 'post_options_metabox' );
// backwards compatible
add_action( 'admin_init', 'post_options_metabox', 1 );
/* Do something with the data entered */
add_action( 'save_post', 'save_post_options' );
/**
* Adds a box to the main column on the Post edit screen
*
*/
function post_options_metabox() {
add_meta_box( 'post_options', __( 'Post Options' ), 'post_options_code', 'post', 'normal', 'high' );
}
/**
* Prints the box content
*/
function post_options_code( $post ) {
wp_nonce_field( plugin_basename( __FILE__ ), $post->post_type . '_noncename' );
$meta_info = get_post_meta( $post->ID, '_meta_info', true) ? get_post_meta( $post->ID, '_meta_info', true) : 1; ?>
<h2><?php _e( 'Meta Information' ); ?></h2>
<div class="alignleft">
<input id="meta_default" type="radio" name="_meta_info" value="meta_default"<?php checked( 'meta_default', $meta_info ); ?><?php echo ( $meta_info == 1 )?' checked="checked"' : ''; ?> /> <label for="meta_default" class="selectit"><?php _e( 'Use default post setting' ); ?></label><br />
<input id="show_meta" type="radio" name="_meta_info" value="show_meta"<?php checked( 'show_meta', $meta_info ); ?> /> <label for="show_meta" class="selectit"><?php _e( 'Show meta info' ); ?></label><br />
<input id="hide_meta" type="radio" name="_meta_info" value="hide_meta"<?php checked( 'hide_meta', $meta_info ); ?> /> <label for="hide_meta" class="selectit"><?php _e( 'Hide meta info' ); ?></label><br />
</div>
<div class="alignright">
<span class="description"><?php _e( 'Your explanation here' ); ?></span>
</div>
<div class="clear"></div>
