当我安装这个 wordpress 插件时，它给了我：

The plugin generated 189 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

这是我的代码：

add_action('wp_head', 'wpse_43672_wp_head', 0);
/**
 * Hooks into the `wp_head` action.
*/
function wpse_43672_wp_head(){ ?>
       <script>
       if (navigator.userAgent.match(/Android/i) ||
             navigator.userAgent.match(/webOS/i) ||
             navigator.userAgent.match(/iPhone/i) ||
             navigator.userAgent.match(/iPad/i) ||
             navigator.userAgent.match(/iPod/i) ||
             navigator.userAgent.match(/BlackBerry/) || 
             navigator.userAgent.match(/Windows Phone/i) || 
             navigator.userAgent.match(/ZuneWP7/i)
             ) {
                // some code
                self.location="<?php echo plugins_url(); ?>/zeevmobile/mobile-page.php";
               }
        </script>
<?php }?>
<style>
li#toplevel_page_zeevmobile-zeevmobile .wp-menu-image {
    background: url(<?php echo plugins_url(); ?>/zeevmobile/images/icon.png) no-repeat 4px !important;
}
</style>
<?php
// create custom plugin settings menu  
add_action('admin_menu', 'zeev_create_menu');  
function zeev_create_menu() {  
    //create new top-level menu  
    add_menu_page('zeev movile redirect', 'zeev mobile', 'administrator', __FILE__, 'zeev_settings_page');  
      //create new top-level menu  
    //call register settings function  
    add_action( 'admin_init', 'register_mysettings' );  
}  
function register_mysettings() {  
    //register our settings  
    register_setting( 'zeev-settings-group', 'zeev_above_text' ); 
    register_setting( 'zeev-settings-group', 'zeev_normal_site' );  
    register_setting( 'zeev-settings-group', 'zeev_mobile_site' );  
} 
function zeev_settings_page() {  
?>  
<div class="wrap">  
<h2>Your Mobile Buttons Links</h2>  
<form method="post" action="options.php">       
    <?php settings_fields('zeev-settings-group'); ?>  
    <table class="form-table">  
        <tr valign="top">  
        <th scope="row">Some text above buttons</th>
        <td><textarea name="zeev_above_text" cols="90"><?php echo get_option('zeev_above_text'); ?></textarea></td>  
        </tr> 
        <tr valign="top">  
        <th scope="row">Normal Site Link</th>
        <td><textarea name="zeev_normal_site" cols="90"><?php echo get_option('zeev_normal_site'); ?></textarea></td>  
        </tr>  
         <tr valign="top">  
        <th scope="row">Mobile Site Link</th>
        <td><textarea name="zeev_mobile_site" cols="90"><?php echo get_option('zeev_mobile_site'); ?></textarea></td>  
        </tr>         
    </table>     
    <p class="submit">  
    <input type="submit" class="button-primary" value="<?php _e('Save Changes') ?>" />  
    </p>  
</form>  
</div>  
<?php }?>

我知道“意外输出”问题来自该文件，因为当我删除其中的所有 php 时，我没有得到问题。你能帮我修一下吗？我在这里上传：http: //zeevm.co.il/zeev-mobile-new.zip

根据评论，错误消息基本上是 WP 抱怨包含文件时正在回显某些内容。

粗略地看一下您的代码，您的标签似乎<style>得到了回应——它不在函数范围内。插件的其他地方可能还有其他类似的问题。
