wordpress给发布文章页添加自定义面板信息

在WordPress发布文章编辑器边上添加自定义面板字段,方便编辑,不用下拉寻找字段名

效果:

代码:

<?php
/*
后台自定义添加关键词和描述面板

*/
//1.创建需要的字段信息
$new_meta_boxes =
array(
"clickurl" => array(
"name" => "clickurl",
"std" => "",
"title" => "直达链接:"),
"clickprice" => array(
"name" => "clickprice",
"std" => "",
"title" => "优惠券金额:") ,
"dropdown" => array(
"name" => "dropdown",
"std" => "",
"subtype"=>array(
"tb"=>"淘宝",
"tmall"=>"天猫",
"jd"=>"京东"
),
"title" => "来源:"
)
);
//2.创建自定义字段输入框
function new_meta_boxes() {
global $post, $new_meta_boxes;

foreach($new_meta_boxes as $meta_box) {
$meta_box_value = get_post_meta($post->ID, $meta_box['name'].'_value', true);

if($meta_box_value == "") {
$meta_box_value = $meta_box['std'];
}


// 自定义字段标题
echo "<div style='padding:10px 0;'>".$meta_box['title']."</div>";

if(isset($meta_box['subtype'])){
echo '<select class="postform" name="'.$meta_box['name'].'_value"> ';
foreach($meta_box['subtype'] as $key => $entry){
if($meta_box_value==$key){
$selected = "selected='selected'";
}else{
$selected ="";
}
echo '<option value="'.$key.'" '.$selected.'>'.$entry .'</option> ';
}
echo '</select>';

}else{

// 自定义字段输入框
echo '<input name="'.$meta_box['name'].'_value" value="'.$meta_box_value.'"><br />';
}
}

echo '<input type="hidden" name="dj_metaboxes_nonce" id="dj_metaboxes_nonce" value="'.wp_create_nonce( plugin_basename(__FILE__) ).'" />';
}
//3.创建自定义字段模块
function create_meta_box() {
global $theme_name;

if ( function_exists('add_meta_box') ) {
add_meta_box( 'new-meta-boxes', '详情信息', 'new_meta_boxes', 'post', 'side', 'low' );
}
}
//4.保存数据

function save_postdata( $post_id ) {
global $new_meta_boxes;

if ( !wp_verify_nonce( $_POST['dj_metaboxes_nonce'], plugin_basename(__FILE__) ))
return;

if ( !current_user_can( 'edit_posts', $post_id ))
return;

foreach($new_meta_boxes as $meta_box) {
$data = $_POST[$meta_box['name'].'_value'];

if($data == "")
delete_post_meta($post_id, $meta_box['name'].'_value', get_post_meta($post_id, $meta_box['name'].'_value', true));
else
update_post_meta($post_id, $meta_box['name'].'_value', $data);
}
}
//5.将函数连接到指定action(动作)
add_action('admin_menu', 'create_meta_box');
add_action('save_post', 'save_postdata');
?>

添加到主题模板文件夹内的function.php里!
