rbncha的代码不是现成的,需要进行大量调整,下面的代码就是我想到的。我添加了一些注释,对所有内容都做了透彻的解释
下面的代码在post的publish块中添加了一个复选框(您可以轻松更改post类型),并在数据库中存储/检索值。通过一些细微的调整,您可以轻松添加文本字段或任何您喜欢的内容
需要注意的是,您必须将主题或插件的my\ucode>更改为唯一键
add_action( 'post_submitbox_misc_actions', 'my_featured_post_field' );
function my_featured_post_field()
{
global $post;
/* check if this is a post, if not then we won't add the custom field */
/* change this post type to any type you want to add the custom field to */
if (get_post_type($post) != 'post') return false;
/* get the value corrent value of the custom field */
$value = get_post_meta($post->ID, 'my_featured_post_field', true);
?>
<div class="misc-pub-section">
<?php //if there is a value (1), check the checkbox ?>
<label><input type="checkbox"<?php echo (!empty($value) ? ' checked="checked"' : null) ?> value="1" name="my_featured_post_field" /> Featured on frontpage</label>
</div>
<?php
}
add_action( 'save_post', 'my_save_postdata');
function my_save_postdata($postid)
{
/* check if this is an autosave */
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return false;
/* check if the user can edit this page */
if ( !current_user_can( 'edit_page', $postid ) ) return false;
/* check if there's a post id and check if this is a post */
/* make sure this is the same post type as above */
if(empty($postid) || $_POST['post_type'] != 'post' ) return false;
/* if you are going to use text fields, then you should change the part below */
/* use add_post_meta, update_post_meta and delete_post_meta, to control the stored value */
/* check if the custom field is submitted (checkboxes that aren't marked, aren't submitted) */
if(isset($_POST['my_featured_post_field'])){
/* store the value in the database */
add_post_meta($postid, 'my_featured_post_field', 1, true );
}
else{
/* not marked? delete the value in the database */
delete_post_meta($postid, 'my_featured_post_field');
}
}
add_action('post_submitbox_misc_actions'、'my_featured_post_field');
函数my_featured_post_字段()
{
全球$员额;
/*检查这是否是一篇文章,如果不是,我们将不添加自定义字段*/
/*将此帖子类型更改为要将自定义字段添加到的任何类型*/
if(get_post_type($post)!=“post”)返回false;
/*获取自定义字段的相应值*/
$value=get_post_meta($post->ID,'my_featured_post_field',true);
?>
选中此->我已检查了更多字段。我们是否可以通过其他方式(如add_meta_box())添加一个新字段?我找不到在高级自定义字段的Publish块中添加复选框的方法。我从未想过在该框中添加一些内容,但有(某种程度上没有文档记录)这样做的方法很酷。将此添加为星号供以后使用!只是一个小更新:publish_in_frontpage()
似乎没有参数,所以我在里面使用了global$post;
,效果很好。这段代码远远不完整/正确,而且不起作用,我怀疑它是否起作用。我在下面添加了我的固定/注释代码。它在最新的WP5中仍然有效吗?它看起来像do_操作(“post_submitbox_misc_actions”)从未在我的应用程序上触发。检查自定义字段是否已提交
您可以在复选框之前添加隐藏字段,并使用相同的名称和值=0。这似乎是一种不好的做法?黑客解决方案?没有-许多框架都会这样做。因此,这可以称为现有做法。
