默认插件设置不写入数据库

时间：2012-04-23 作者：Zach

我的插件设置如下：

主插件文件mouldings.php

<?php

/*
Plugin Name: Moulding Profiles
Plugin URI: 
Description: Creates a \'Moulding Profiles\' and \'Idea Gallery\' custom post type, creates a \'Wood Types\' and \'Categories\' taxonomy for \'Moulding Profiles\'
Version: 0.1
Author: 
Author URI: 
License: GPL2
*/

// Global Variables
$mouldings_prefix = \'mouldings_\';
$mouldings_name = \'Mouldings\';


// plugin folder url
if(!defined(\'MOULDINGS_BASE_URL\')) {
    define(\'MOULDINGS_BASE_URL\', plugin_dir_url(__FILE__));
}
// plugin folder path
if(!defined(\'MOULDINGS_BASE_DIR\')) {
    define(\'MOULDINGS_BASE_DIR\', plugin_dir_path( __FILE__ ));
}
// plugin root file
if(!defined(\'MOULDINGS_PLUGIN_FILE\')) {
    define(\'MOULDINGS_PLUGIN_FILE\', __FILE__);
}

// Includes
include(\'includes/register-settings.php\'); // Register

// Retrieve settings from the options page
$mouldings_options = get_option(\'mouldings_settings\');

include(\'includes/install.php\'); // Sets default plugin settings on activation
include(\'includes/plugin-settings.php\'); // Plugin options page HTML/Save functions
include(\'includes/scripts.php\'); // Conrols JS/CSS
include(\'includes/admin-post-types.php\'); // Sets up post types/taxonomies
include(\'includes/helper-functions.php\'); // Functions that extend functionality of Mouldings
include(\'includes/admin-metaboxes.php\'); // Metaboxes that appear in the admin (non-ACF)
include(\'includes/display-functions.php\'); // Holds filters/actions for output

?>
在中register_settings.php 我已设置选项：

<?php

function mouldings_register_settings_initial() {

    if( false == get_option( \'mouldings_settings\' ) ) {  
        add_option( \'mouldings_settings\' );  
    }

    register_setting(\'mouldings_settings_group\', \'idea_gallery_thumb_height\');
    register_setting(\'mouldings_settings_group\', \'idea_gallery_thumb_width\');
    register_setting(\'mouldings_settings_group\', \'collection_thumb_height\');
    register_setting(\'mouldings_settings_group\', \'collection_thumb_width\');
    register_setting(\'mouldings_settings_group\', \'profile_item_columns\');
    register_setting(\'mouldings_settings_group\', \'idea_item_columns\');
    register_setting(\'mouldings_settings_group\', \'collections_item_columns\');
    register_setting(\'mouldings_settings_group\', \'combinations_item_columns\');

}
add_action(\'admin_init\', \'mouldings_register_settings_initial\');
然后进来install.php

<?php

function mouldings_activate() {
    global $wpdb, $mouldings_options;
    if ($mouldings_options === false){
        $mouldings_options = array(
            \'idea_item_columns\' => \'4\'
        );
        update_option( \'mouldings_settings\', $mouldings_options );
    }
}
register_activation_hook( MOULDINGS_PLUGIN_FILE, \'mouldings_activate\' );
所以，我要做的是设置选项表条目，moulding_settings, 注册设置，然后在激活时设置测试值，idea_item_colummns 到4. 当前激活时，将创建选项表条目，但没有任何设置和默认值idea_item_columns 也未设置/创建。一旦我访问了我的设置页面并保存了这些值，它们会根据需要弹出在该表中，但似乎没有单击激活。这是我的设置页面，如果有帮助的话：

<?php

function mouldings_options_page() {

    global $mouldings_options;

    ob_start(); ?>

        <h2><?php _e(\'Mouldings Options\',\'roots\'); ?></h2>

我已经做了几个小时了，我希望这是一件小事（好吧，如果太小了，我可能会失去理智，但任何帮助都将不胜感激）。谢谢

我认为问题在于，您最初设置设置的功能在激活时无法运行。在激活挂钩中添加对Moldings\\u register\\u settings\\u initial（）的调用，如下所示：

function mouldings_activate() {
    global $wpdb, $mouldings_options;
    mouldings_register_settings_initial();
    if ($mouldings_options === false){
        $mouldings_options = array(
            \'idea_item_columns\' => \'4\'
        );
        update_option( \'mouldings_settings\', $mouldings_options );
    }
}
register_activation_hook( MOULDINGS_PLUGIN_FILE, \'mouldings_activate\' );

结束
