update_post_meta没有保存到wordpress数据库

我正在开发一个插件，以便房地产公司可以使用自定义帖子类型发布他们的属性。我可以在管理菜单上显示自定义帖子类型。但是，当我尝试保存帖子时，我的自定义元框中的信息不会更新以传达更改。我很好奇它是否与save_post挂钩有关，或者它是否是我没有看到的其他东西。下面的代码是我的整个插件。

<?php
/*
* Plugin Name: Real Estate Post Type

register_activation_hook( __FILE__, 'realEstatePostTypeActivation');

function realEstatePostTypeActivation(){
}

function my_admin(){    
    add_meta_box(
    'residential_meta_box',
    'Property Information',
    'displayPostMetaBox',
    'residentialProperty',
    'normal');

    add_meta_box(
    'commercial_meta_box',
    'Property Information',
    'displayPostMetaBox',
    'commercialProperty',
    'normal');  

}

add_action('admin_init', 'my_admin');

function displayPostMetaBox($post){

    $meta = get_post_meta($post->ID);

    $address = !empty($meta['address']) ? $meta['address'] : '';
    $rent = !empty($meta['rent']) ? $meta['rent'] : '';

首先，你的代码第45行附近有一个错误。没有定义名为lot的索引。

接下来，您尝试在自定义字段中显示的是从数据库中检索的值数组。尝试为其添加索引。

然后，在执行挂钩到save_post操作的函数之前，尝试删除检查post类型的代码。

答案 1 :(得分：0)

该问题属于与“save_post”操作相关联的功能。我没有使用传递给addPropertyFields（）的$ post变量，而是使用了全局$ post变量。

function addPropertyFields($post_id){
    global $post;

    if($post->post_type != "property"){
        return;
    }

    add_post_meta($post_id, 'address', $_POST['address']) or update_post_meta($post_id, 'address', $_POST['address'], get_post_meta($post_id, 'address', true));
}

add_action('save_post', 'addPropertyFields');
