Tom McFarlinのBoilerplateリポジトリをテンプレートとして使用して、OOPプラクティスを利用するプラグインを開発しています。設定を正しく送信できない理由を正確に把握しようとしています。ここで別の質問で提案されているように、アクション属性を空の文字列に設定しようとしましたが、それは助けにはなりませんでした...
以下は、私が使用している一般的なコード設定です...
フォーム(/views/admin.php):
<div class="wrap">
<h2><?php echo esc_html( get_admin_page_title() ); ?></h2>
<form action="options.php" method="post">
<?php
settings_fields( $this->plugin_slug );
do_settings_sections( $this->plugin_slug );
submit_button( 'Save Settings' );
?>
</form>
</div>
以下のコードでは、 'option_list_selection'を除き、add_settings_field()およびadd_settings_section()のすべてのコールバックが存在すると仮定します。
プラグイン管理クラス(/{plugin_name}-class-admin.php):
namespace wp_plugin_name;
class Plugin_Name_Admin
{
/**
* Note: Some portions of the class code and method functions are missing for brevity
* Let me know if you need more information...
*/
private function __construct()
{
$plugin = Plugin_Name::get_instance();
$this->plugin_slug = $plugin->get_plugin_slug();
$this->friendly_name = $plugin->get_name(); // Get "Human Friendly" presentable name
// Adds all of the options for the administrative settings
add_action( 'admin_init', array( $this, 'plugin_options_init' ) );
// Add the options page and menu item
add_action( 'admin_menu', array( $this, 'add_plugin_admin_menu' ) );
}
public function add_plugin_admin_menu()
{
// Add an Options Page
$this->plugin_screen_hook_suffix =
add_options_page(
__( $this->friendly_name . " Options", $this->plugin_slug ),
__( $this->friendly_name, $this->plugin_slug ),
"manage_options",
$this->plugin_slug,
array( $this, "display_plugin_admin_page" )
);
}
public function display_plugin_admin_page()
{
include_once( 'views/admin.php' );
}
public function plugin_options_init()
{
// Update Settings
add_settings_section(
'maintenance',
'Maintenance',
array( $this, 'maintenance_section' ),
$this->plugin_slug
);
// Check Updates Option
register_setting(
'maintenance',
'plugin-name_check_updates',
'wp_plugin_name\validate_bool'
);
add_settings_field(
'check_updates',
'Should ' . $this->friendly_name . ' Check For Updates?',
array( $this, 'check_updates_field' ),
$this->plugin_slug,
'maintenance'
);
// Update Period Option
register_setting(
'maintenance',
'plugin-name_update_period',
'wp_plugin_name\validate_int'
);
add_settings_field(
'update_frequency',
'How Often Should ' . $this->friendly_name . ' Check for Updates?',
array( $this, 'update_frequency_field' ),
$this->plugin_slug,
'maintenance'
);
// Plugin Option Configurations
add_settings_section(
'category-option-list', 'Widget Options List',
array( $this, 'option_list_section' ),
$this->plugin_slug
);
}
}
リクエストされた更新:
アクション属性を次のように変更します。
<form action="../../options.php" method="post">
...単に404エラーになります。以下は、Apacheログの抜粋です。デフォルトのWordPressスクリプトとCSSエンキューが削除されることに注意してください。
