Wordpress試圖激活錯誤的插件

Question

當我嘗試激活我寫的一個插件時，wordpres會嘗試激活錯誤的插件，我說我去Plugins->Installed Plugins並激活，wordpress會返回'anspress'插件無法提供的錯誤消息被發現。

我的插件名稱爲「Academy」，文件夾名稱爲「academy」，插件文件名爲「academy.php」。

academy.php內容：

<?php 
/** 
* @package Academy 
*/ 
/* 
Plugin Name: Academy 
Description: Academy features 
Version: 0.1 
Author: Victor Aurélio Santos 
Text Domain: academy 
*/ 

/* is_plugin_active */ 
include_once(ABSPATH . 'wp-admin/includes/plugin.php'); 

define ('ACADEMY_INCLUDE', plugin_dir_path(__FILE__) . '/include'); 
define ('ACADEMY_TEMAPLE', ACADEMY_INCLUDE . '/templates'); 

global $academy_err; $academy_err = array(); 

$plugin_dependencies = array('woocommerce' => false, 
         'anspress' => false); 

/* Dependencies check */ 
foreach ($plugin_dependencies as $plugin => &$enabled) { 
    if (! $enabled = is_plugin_active("{$plugin}/{$plugin}.php")) { 
    $academy_err[] = "The {$plugin} plugin isn't installed and/or activated."; 
    } 
} 

/* Check current theme, if not 'Academy' don't load files that depends... */ 
if ("Academy" == wp_get_theme()->Name) { 
    include ACADEMY_INCLUDE . '/buddypress/bp-loader.php'; 
    include ACADEMY_INCLUDE . '/news-feed.php'; 
} else { 
    $academy_err[] = "Current theme isn't \"Academy\" not loading NewsFeed..."; 
} 

/* Check for woocommerce */ 
if ($plugin_dependencies['woocommerce'] && $plugin_dependencies['anspress']){ 
    include ACADEMY_INCLUDE . '/anspress-woocommerce.php'; 
} 

include (ACADEMY_INCLUDE . '/settings.php'); 


function academy_admin_notices() { 
    global $academy_err; 

    foreach ($academy_err as $err) { 
?> 
    <div class="update-nag"> 
     <p>Academy Error: <?php echo $err; ?></p> 
    </div> 
<?php 
    } 
} 
add_action('admin_notices', 'academy_admin_notices'); 

function academy_init() { 
    $plugin_dir = basename(dirname(__FILE__)) . '/languages'; 
    load_plugin_textdomain('academy', false, $plugin_dir); 
} 
add_action('plugins_loaded', 'academy_init'); 

function academy_plugin_action_links ($links, $file) { 
    static $this_plugin; 

    if (!$this_plugin) { 
    $this_plugin = plugin_basename(__FILE__); 
    } 

    if ($file == $this_plugin) { 
    $settings_link = '<a href="' . get_bloginfo('wpurl') . '/wp-admin/admin.php? page=academy-settings">' . __('Settings', 'academy') . '</a>'; 
    array_unshift($links, $settings_link); 
    } 

    return $links; 
} 
add_filter('plugin_action_links', 'academy_plugin_action_links', 10, 2); 

我認爲這是錯誤的東西與我的插件，卻找不到什麼。

在插件的根源處，我們應該不惜一切代價直接調用WordPress函數。最好的做法是將所有內容都封裝在相關的鉤子中。

但是，功能get_option可以安全使用。有了它，我們處理include s。

其餘的，我們使用register_activation_hook來激活激活插件。要檢查所需插件的激活/停用，我們可以使用鉤子activate_$pluginName和deactivate_$pluginName。主題狀態更改可以使用鉤子after_switch_theme捕獲。

    update_option('academy_err', $academy_err); 
}

_{首先oop和擺脫define S和global小號，here's a nice plugin base。}

你的插件依賴於另一個名爲'anspress'，這就是爲什麼你會得到這個錯誤。這從您的代碼段是問題來源：

$plugin_dependencies = array('woocommerce' => false, 
         'anspress' => false); 

/* Dependencies check */ 
foreach ($plugin_dependencies as $plugin => &$enabled) { 
    if (! $enabled = is_plugin_active("{$plugin}/{$plugin}.php")) { 
    $academy_err[] = "The {$plugin} plugin isn't installed and/or activated."; 
    } 
} 

要麼添加插件，「anspress」，這是標記爲依賴或從陣列中刪除。
