Php Drupal 7：提交后的高级主题设置

我对theme-settings.php中的高级设置有问题。我可以用这个-->

功能。但提交设置后如何集成新功能？像这样：

mytheme_system_theme_settings_submit_alter($form, &$form_state) {
  // if form submited -> execute function
}

---

您可以在alter函数本身中将自定义提交处理程序添加到表单中：

function mytheme_form_system_theme_settings_alter(&$form, &$form_state) {
  // Build up the rest of the form.

  // Add your submission handler to the form.
  $form['#submit'][] = 'mytheme_form_system_theme_settings_submit';
}

function mytheme_form_system_theme_settings_submit(&$form, &$form_state) {
  // Form has been submitted, execute your function.
}

---

当我执行此操作时，会出现以下错误：在第1460行的includes/form.inc中调用未定义的函数mytheme\u form\u system\u theme\u settings\u submit（）。有什么想法吗？您需要用主题的名称替换

my\u theme

）哈，我这么做了，只是把它重新格式化成你拥有的。上面的每个地方都有“mytheme”，我有“cdf”，所以我的错误是：cdf\u form\u system\u theme\u settings\u submit（）。真奇怪。有什么想法吗？

function mytheme_form_system_theme_settings_alter(&$form, &$form_state) {
  // Build up the rest of the form.

  // Add your submission handler to the form.
  $form['#submit'][] = 'mytheme_form_system_theme_settings_submit';
}

function mytheme_form_system_theme_settings_submit(&$form, &$form_state) {
  // Form has been submitted, execute your function.
}
