我已经为我的插件使用设置API有一段时间了，它过去工作得很好。现在它坏了，我不知道为什么。显然，甚至没有调用选项验证函数。不过，表单数据是正确发送和接收的。（两者均由echo resp公司print_r 调试。）

我总结了一个（希望是）最小但可运行的示例，它既保留了我所做的工作的特点，又保留了我如何做的结构：

myplugin.php

<?php
/*
Plugin Name: My Plugin
Plugin URI: http://wordpress.org/extend/plugins/myplugin/
Description: Example plugin.
Version: 1.0
Author: Your Name
Author URI: http://your.site
License: GPL2
*/
?>
<?php

require_once(\'Plugin.php\');

class MyPlugin extends Plugin {

  function __construct() {
    parent::__construct(array(\'name\' => \'myplugin\',
                              \'prettyName\' => \'My Plugin\',
                              \'mainFile\' => __FILE__));
  }

  function activate() {
    if ( !get_option($this->name) ) {
      $options = array( \'test\' => \'testwert\' );
      add_option($this->name, $options);
    }
  }

  function deactivate() {}

  function options_validate($input) {
    $options = get_option($this->name);

    $options[\'test\'] = empty($input[\'test\']) ? $options[\'test\'] : $input[\'test\'];

    return $options;
  }

  function setup_settings() {
    parent::setup_settings();
    include(\'settings.inc.php\');
  }
}

new MyPlugin();
?>

Plugin.php

<?php
if ( !class_exists(\'Plugin\') ) {

abstract class Plugin {
  protected $name;
  protected $prettyName;
  protected $mainFile;
  private $hasOptions = true;
  protected $options;

  function __construct($props, $hasOptions = true) {
    $this->name = $props[\'name\'];
    $this->prettyName = $props[\'prettyName\'];
    $this->mainFile = $props[\'mainFile\'];
    $this->hasOptions = $hasOptions;

    if ( $hasOptions ) {
      if ( is_admin() ) {
        // Register Options Page
        add_action(\'admin_menu\', array(&$this, \'admin_menu_init\'));
        // Register settings
        add_action(\'admin_init\', array(&$this, \'setup_settings\'));
      }

      $this->options = get_option($this->name);
    }

    register_activation_hook($this->mainFile, array(&$this, \'activate\'));
    register_deactivation_hook($this->mainFile, array(&$this, \'deactivate\'));
  }

  function admin_menu_init() {
    add_options_page($this->prettyName.\' -- Options\', $this->prettyName, \'manage_options\', basename($this->mainFile), array(&$this, \'options_page\'));
  }

  abstract function options_validate($input);

  function setup_settings() {
    register_setting($this->name, $this->name, array(&$this, \'options_validate\'));
  }

  function options_page() { ?>
    <div class="wrap">
      <h2><?php echo $this->prettyName; ?> &ndash; Settings</h2>
      <form action="" method="post">
        <?php submit_button(); ?>
        <?php settings_fields($this->name); ?>
        <?php do_settings_sections($this->name); ?>
        <?php submit_button(); ?>
      </form>
    </div> <?php
  }

  abstract function activate();

  abstract function deactivate();
}

}
?>

settings.inc.php

<?php

class MyPluginCallbacks {
  private $name = null;
  private $options = null;

  function __construct($name, $options) {
    $this->name = $name;
    $this->options = $options;
  }

  function general_text() {
    echo \'A simple options page demonstration\';
  }

  function test() {
    echo "<input id=\'sanitisation\' name=\'{$this->name}[test]\' type=\'text\' value=\'{$this->options[\'test\']}\'/>\\n";
    echo "<br /><small>A simple test value.</small>";
  }
}

$callbacks = new MyPluginCallbacks($this->name, $this->options);

add_settings_section(\'general\', \'General\', array(&$callbacks, \'general_text\'), $this->name);
add_settings_field(\'test\', \'Test Value:\', array(&$callbacks, \'test\'), $this->name, \'general\');

?>

可通过测试插件在WP 3.3和最新版本上复制。没有可见的调试消息（启用了WP\\U调试）。

编辑：更改的是选项页面。过去是这样的options.php 但这已经不起作用了。现在是了options-general.php.

<form action="" method="post">

<form action="options.php" method="post">
