Question

我使用插件https://wordpress.org/plugins/show-post-in-lightbox/来显示页面上每个帖子的所有功能图像。当这些图像中的一个被点击在灯箱上时，将显示帖子内容。

这一切都很好，但显示内容的原始代码使用：

if($_REQUEST['popup']!=''){
$postObj = get_post( $_REQUEST['pid'] );
echo $postObj->post_content;
exit;
}

除了不太需要因为wordpress无法格式化html之外，这个工作正常。 wordpress也不会识别短代码。所以我决定让脚本确保它运行良好，我可以使用短代码：

if($_REQUEST['popup']!=''){

$postObj = $_POST['pid'];
$content_post = get_post($$postObj);
$content = $content_post->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]&gt;', $content);
echo $content;
exit;
}

但是这给了我错误：在打开灯箱时加载灯箱时出错。当我删除APPLT_FILTERS行时它不会出错（但是因为我需要那行它不会显示任何东西）

但我认为它可以假设

$content = apply_filters('the_content', $content);

是灯箱崩溃的那个。这段代码都在插件文件中。有谁知道为什么上面的代码生成和500崩溃？

希望有人可以帮助我！

整个代码：

 if($_REQUEST['popup']!=''){

$postObj = $_POST['pid'];
$content_post = get_post($$postObj);
$content = $content_post->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]&gt;', $content);
echo $content;
}

您检查过Apache / PHP错误日志文件吗？这对于调试至关重要：）

我注意到你的代码有两个问题 - 但纠正它们可能实际上并没有修复500。

这几行并不符合你的意图：

$postObj = $_POST['pid'];
$content_post = get_post($$postObj);

将$_POST['pid']更改为$_REQUEST['pid']。 pid查询变量未被POST。

将$$postObj更改为$postObj。想象一下$_REQUEST['pid']返回123（样本帖ID）。致电$$postObj实际上会尝试拨打$123;该变量既不存在又无效，因为它以数字开头。

WordPress的。 apply_filter上的lightbox插件错误
