我到学习有关创建WP插件,所以我阅读此页 - http://codex.wordpress.org/Creating_Options_Pages创建WP插上
我尝试在页面这是下面的代码给出的示例:
<?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,但当我在WP管理员测试窗体时,当我在窗体中插入数据并单击更新按钮时,没有“更新消息”出现。
所以我的问题是当人们在表单中插入数据并点击提交按钮时,如何使'更新消息'或'错误消息'出现。
非常感谢您的帮助!
