我已经有很长一段时间没有做过任何元框了，所以我很快就为我正在开发的网站做了这个元框。

我的问题是，当我在框中输入一些文本并点击“保存”时，文本会消失，所以我只剩下空文本框，没有保存的数据。

我猜这和我的save_post 作用

更新*现在标题字段可以工作，但内容字段不能工作。

//intialising the metabox and using the callback function



add_action( \'add_meta_boxes\', \'owl_mb_create\' );

function owl_mb_create() {

        add_meta_box( \'owl-meta\', \' Inner Page Box\', \'owl_mb_function\', \'page\', \'normal\', \'high\' );

}

?>


<?php

function owl_mb_function( $post ) {

        //retrieve the metadata values if they exist
        $owl_mb_content_one = get_post_meta( $post->ID, \'owl_mb_content_one\', true);
        $owl_mb_title_one = get_post_meta( $post->ID, \'owl_mb_title_one\', true);
        $owl_mb_content_two = get_post_meta( $post->ID, \'owl_mb_content_two\', true);
        $owl_mb_title_two = get_post_meta( $post->ID, \'owl_mb_title_two\', true);
        $owl_mb_content_three = get_post_meta( $post->ID, \'owl_mb_content_three\', true);
        $owl_mb_title_three = get_post_meta( $post->ID, \'owl_mb_title_three\', true);

        echo \'Please fill in the forms below\';
