我有两个使用设置API创建的表单，当我保存其中一个表单时，另一个表单会被删除，反之亦然。

这是完整的代码，您可以将其粘贴到函数中。php文件并亲自查看：

// Register settings
function registerSettings() {

register_setting(\'XX_theme_settings\', \'XX_theme_settings\' );

add_settings_section(\'theme_options\', \'Theme Options\', \'theme_options_generate\', \'page1\' ); 
add_settings_field( \'XX_Option1\', \'Option 1\', \'text_input\', \'page1\', \'theme_options\', \'XX_Option1\' );
add_settings_field( \'XX_Option2\', \'Option 2\', \'text_input\', \'page1\', \'theme_options\', \'XX_Option2\' ); 
add_settings_field( \'XX_Option3\', \'Option 3\', \'textarea\', \'page1\', \'theme_options\', \'XX_Option3\');  
add_settings_field( \'XX_Option4\', \'Option 4\', \'textarea\', \'page1\', \'theme_options\', \'XX_Option4\');  

add_settings_section(\'theme_options2\', \'Theme Options2\', \'theme_options_generate2\', \'page2\' ); 
add_settings_field( \'XX_Option5\', \'Option 5\', \'text_input\', \'page2\', \'theme_options2\', \'XX_Option5\' );
add_settings_field( \'XX_Option6\', \'Option 6\', \'text_input\', \'page2\', \'theme_options2\', \'XX_Option6\' ); 
add_settings_field( \'XX_Option7\', \'Option 7\', \'textarea\', \'page2\', \'theme_options2\', \'XX_Option7\');  
add_settings_field( \'XX_Option8\', \'Option 8\', \'textarea\', \'page2\', \'theme_options2\', \'XX_Option8\');     

};

add_action(\'admin_init\', \'registerSettings\');

//Generate section 1    
function theme_options_generate() {
     echo \'This is a Settings Section 1\';
 }
//Generate section 2
function theme_options_generate2() {
     echo \'This is a Settings Section 2\';
 }

//Generate text input callback    
function text_input($args) {
    $options = get_option(\'XX_theme_settings\');
    echo "<input id=". $args ." name=\'XX_theme_settings[". $args ."]\' size=\'40\' type=\'text\' value=\'{$options[$args]}\' />";   
 }

//Generate textarea callback    
 function textarea($args) {
    $options = get_option(\'XX_theme_settings\');
    echo "<textarea id=". $args ." name=\'XX_theme_settings[". $args ."]\' rows=\'7\' cols=\'50\' type=\'textarea\'>{$options[$args]}</textarea>";
 }

//Add admin pages
function registerMenus() {

add_menu_page(\'Theme Options\', \'Theme Options\', \'edit_theme_options\', \'theme_menu_slug\', \'theme_options_page\'); 
add_menu_page(\'Theme Options2\', \'Theme Options2\', \'edit_theme_options\', \'theme_menu_slug2\', \'theme_options_page2\'); 

};

add_action(\'admin_menu\', \'RegisterMenus\'); 

//Generate Page1 form
function theme_options_page() { ?>
   <form action="options.php" method="post">
   <?php settings_fields(\'XX_theme_settings\'); do_settings_sections(\'page1\'); ?>
   <p class="submit">  <input name="Submit" type="submit" class="button-primary" value="<?php _e(\'Save Changes\'); ?>" /></p> 
   </form>

   <pre><?php echo var_dump(get_option(\'XX_theme_settings\')); ?></pre>

<?php }

//Generate Page2 form
function theme_options_page2() { ?> 
   <form action="options.php" method="post">
   <?php settings_fields(\'XX_theme_settings\'); do_settings_sections(\'page2\'); ?>
   <p class="submit">  <input name="Submit" type="submit" class="button-primary" value="<?php _e(\'Save Changes\'); ?>" /></p> 
   </form>

   <pre><?php echo var_dump(get_option(\'XX_theme_settings\')); ?></pre>

<?php } ?>

我知道我还没有验证数据，但我想它应该是现成的（而不是每次都使用整个阵列），对吗？出了什么问题？

XX_theme_settings=array(\'XX_Option1\' =>\'input1\',\'XX_Option2\'=>\'input2\',...)
