Question

我想在扩展程序中设置页面标题，因此流体模板中的当前{page}对象也将显示设置的标题。

$GLOBALS['TSFE']->altPageTitle = $pageTitle;仅设置<title>标签，对{page.title}无效

我的主要目标：在面包屑中显示详细信息页面的“正确”标题。

有什么方法可以操纵它吗？

Answer 1

对于缓存的页面和插件，这应该可以工作：

$GLOBALS['TSFE']->page['title'] = $pageTitle;

Answer 2

我对流体中的{page}对象一无所知，所以我使用了一个与here中的对象相似的ViewHelper来实现它。

/**
 * A view helper for setting the document title in the <title> tag.
 *
 * = Examples =
 *
 * <page.title mode="prepend" glue=" - ">{blog.name}</page.title>
 * 
 * <page.title mode="replace">Something here</page.title>
 * 
 * <h1><page.title mode="append" glue=" | " display="render">Title</page.title></h1>
 *

 */
class PageTitleViewHelper extends \TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper {

  /**
   * @var bool
   */
  protected $escapeOutput = false;

    /**
     * @param string $mode Method for adding the new title to the existing one.
     * @param string $glue Glue the new title to the old title with this string.
     * @param string $display If render, this tag displays it's children. By default it doesn't display anything.
     * @return string Rendered content or blank depending on display mode.

     */
    public function render($mode = 'replace', $glue = ' - ', $display = 'none') {

        $renderedContent = $this->renderChildren();

        $existingTitle = $GLOBALS['TSFE']->page['title'];

        if ($mode === 'prepend' && !empty($existingTitle)) {
            $newTitle = $renderedContent.$glue.$existingTitle;
        } else if ($mode === 'append' && !empty($existingTitle)) {
            $newTitle = $existingTitle.$glue.$renderedContent;
        } else {
            $newTitle = $renderedContent;
        }

        $GLOBALS['TSFE']->page['title'] = $newTitle;
        $GLOBALS['TSFE']->indexedDocTitle = $newTitle;


        if ($display === 'render') {
            return $renderedContent;
        } else {
            return '';
        }
    }
}
