这是一个漫长的两天，试图从零开始编程一个插件，以提供一个包含2个表单的前端登录页。

根据用户想要使用的表单，表单应更改数据库中的值（如果不存在自定义字段“key”=>“value”，则添加或创建）。

如果运气不好，对与操纵$\\u POST和获取其价值等相关的表单和功能进行了多次更改，但都没有成功！

有人愿意看看我下面的代码吗？目的是在提交时区分两种表格。之后，如果按下第二个提交按钮，则会在wp\\U Posteta表中更新自定义字段值。

<?php
$lucs_stored_meta = get_post_meta($post->ID);

// salt shaker, drawing straws, randomness
function lucs_random_thumbnail() {
        $lucs_random_image = rand(0,1);
        if ($lucs_random_image == 0) {
                $lucs_thumb_ra = plugins_url(\'/img/thumb0.png\',__FILE__);
        } else {
                $lucs_thumb_ra = plugins_url(\'/img/thumb1.png\',__FILE__);
        }
        return $lucs_thumb_ra;
}

// if participant has no featured image, display the following default image included in plugin
function lucs_get_featured_image() {
        if (has_post_thumbnail()) {
                the_post_thumbnail(\'thumbnail\',array( \'class\' => \'showcase-thumbnail\' ));
        } else {
                echo \'<img src="\' . lucs_random_thumbnail() . \'" class="showcase-thumbnail" alt="Organization">\';
        }
}
