Question

我在面板ipe工具栏中添加了自定义按钮。工具栏仅在您具有正确权限时以及页面是面板化页面时显示。我想为其他页面显示ipe工具栏，其中包含该页面的选项卡（view / edit / devel / translate）。有可能吗？

Answer 1

是的，这是可能的。我的一个项目中有类似的需求。我在自定义模块中所做的是：

使用hook_page_alter在按钮DON＆T存在时添加ipe工具栏（面板IPE在它们存在时添加它们）
使用hook_theme_registry_alter来使用我自己的模板功能，而不是Panels IPE提供的功能。
创建添加自定义按钮的自定义主题功能

在代码中它是这样的：

/**
 * Implements of hook_page_alter()
 */
function MYMODULE_page_alter(&$page) {
  // Check if Panels IPE is turned on.
  if (!module_exists('panels_ipe'))
    return;

  // Let Panels IPE add the buttons if they exist > If there are no buttons
  // then we'll still add the toolbar anyway.
  $buttons = &drupal_static('panels_ipe_toolbar_buttons', array());
  if (!empty($buttons)) {
    return;
  }

  $output = theme('panels_ipe_toolbar', array('buttons' => $buttons));

  $page['page_bottom']['panels_ipe'] = array(
    '#markup' => $output,
  );
}

/**
 * Implements hook_theme_registry_alter().
 */
function MYMODULE_theme_registry_alter(&$theme_registry) {
  // Check if Panels IPE is turned on.
  if (!module_exists('panels_ipe'))
    return;
  // Inject our own theme function instead of the one from Panels IPE
  $theme_registry['panels_ipe_toolbar']['function'] = 'theme_MYMODULE_panels_ipe_toolbar';
}

// This function is to be adjusted to add buttons and things.
function theme_MYMODULE_panels_ipe_toolbar($vars) {
  $buttons = $vars['buttons'];

  $output = "<div id='panels-ipe-control-container' class='clearfix'>";
  foreach ($buttons as $key => $ipe_buttons) {
    $output .= "<div id='panels-ipe-control-$key' class='panels-ipe-control'>";

    // Controls in this container will appear when the IPE is not on.
    $output .= '<div class="panels-ipe-button-container clearfix">';
    foreach ($ipe_buttons as $button) {
      $output .= is_string($button) ? $button : drupal_render($button);
    }
    $output .= '</div>';

    // Controls in this container will appear when the IPE is on. It is usually
    // filled via AJAX.
    $output .= '<div class="panels-ipe-form-container clearfix"></div>';
    $output .= '</div>';
  }

  $output .= "</div>";

  return $output;
}
