我到學習有關創建WP插件,所以我閱讀此頁 - http://codex.wordpress.org/Creating_Options_Pages創建WP插上
我嘗試在頁面這是下面的代碼給出的示例:
<?php
// create custom plugin settings menu
add_action('admin_menu', 'baw_create_menu');
function baw_create_menu() {
//create new top-level menu
add_menu_page('BAW Plugin Settings', 'BAW Settings', 'administrator', __FILE__, 'baw_settings_page',plugins_url('/images/icon.png', __FILE__));
//call register settings function
add_action('admin_init', 'register_mysettings');
}
function register_mysettings() {
//register our settings
register_setting('baw-settings-group', 'new_option_name');
register_setting('baw-settings-group', 'some_other_option');
register_setting('baw-settings-group', 'option_etc');
}
function baw_settings_page() {
?>
<div class="wrap">
<h2>Your Plugin Name</h2>
<form method="post" action="options.php">
<?php settings_fields('baw-settings-group'); ?>
<table class="form-table">
<tr valign="top">
<th scope="row">New Option Name</th>
<td><input type="text" name="new_option_name" value="<?php echo get_option('new_option_name'); ?>" /></td>
</tr>
<tr valign="top">
<th scope="row">Some Other Option</th>
<td><input type="text" name="some_other_option" value="<?php echo get_option('some_other_option'); ?>" /></td>
</tr>
<tr valign="top">
<th scope="row">Options, Etc.</th>
<td><input type="text" name="option_etc" value="<?php echo get_option('option_etc'); ?>" /></td>
</tr>
</table>
<p class="submit">
<input type="submit" class="button-primary" value="<?php _e('Save Changes') ?>" />
</p>
</form>
</div>
<?php } ?>
一切都很好,但當我在WP管理員測試窗體時,當我在窗體中插入數據並單擊更新按鈕時,沒有「更新消息」出現。
所以我的問題是當人們在表單中插入數據並點擊提交按鈕時,如何使'更新消息'或'錯誤消息'出現。
非常感謝您的幫助!
