如何更改 Phoca Gallery 图片页面的元标签？
How to change Phoca Gallery image pages Meta Tags?
我正在使用 Joomla 2.5 的 Phoca Gallery，对于画廊中的每张图片，我都有不同的带有元标记的页面。但是对于那些图像，我只有标题。而且我想把这些图片的描述和它们的标题一样。
我在 Joomla 中找到了我需要更改的文件的位置：
/components/com_phocagallery/views/detail/view.html.php
，但我找不到如何更改它。
这是这个文件的代码：

在哪里改变什么？
查看方法：
protected function _prepareDocument($item)（在所列代码的底部）
您在变量中设置了标题，这样您就可以将其添加到元标记中。您可以在此方法中看到其他变量设置为元标记。因此，您可以使用这些并将标题添加为元标记。
例如：
$this->document->setDescription($title);
我正在使用 Joomla 2.5 的 Phoca Gallery，对于画廊中的每张图片，我都有不同的带有元标记的页面。但是对于那些图像，我只有标题。而且我想把这些图片的描述和它们的标题一样。
我在 Joomla 中找到了我需要更改的文件的位置：
/components/com_phocagallery/views/detail/view.html.php
，但我找不到如何更改它。

在哪里改变什么？
查看方法： protected function _prepareDocument($item)（在所列代码的底部）
您在变量中设置了标题，这样您就可以将其添加到元标记中。您可以在此方法中看到其他变量设置为元标记。因此，您可以使用这些并将标题添加为元标记。
例如：
$this->document->setDescription($title);
