WordPress的. apply_filter上的灯箱插件错误 [英] wordpress. lightbox plugin error on apply_filter
问题描述
我使用了插件 https://wordpress.org/plugins/show-post -in-lightbox/在页面上显示每个帖子的所有精选图片.每当这些图片之一被点击时，都会出现一个灯箱，显示帖子内容.
I use the plugin https://wordpress.org/plugins/show-post-in-lightbox/ to display all feautered image of every post on a page. whenver one of these images get clicked on a lightbox will appear showing the post content.
一切正常，但是显示内容的原始代码使用:
This all works fine but the original code that display the content uses:
if($_REQUEST['popup']!=''){
$postObj = get_post( $_REQUEST['pid'] );
echo $postObj->post_content;
exit;
}
这不是很好，因为wordpress无法格式化html，因此效果很好. Wordpress也不会识别简码.因此，我决定尝试使用脚本来确保其正常运行，并可以使用简码:
This works fine besides the fact that its not very need because wordpress cant format the html. also wordpress wont recognize shortcodes. So I decided to chance the script to make sure it works good and I can use shortcodes:
if($_REQUEST['popup']!=''){
$postObj = $_POST['pid'];
$content_post = get_post($$postObj);
$content = $content_post->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
echo $content;
exit;
}
但这给我一个错误:打开灯箱时加载灯箱时出错.当我删除APPLT_FILTERS行时，它不会出错(但是因为我需要该行，所以它也不会显示任何内容)
But this gives me the error: error loading lightbox on opening the lightbox. When i delete the APPLT_FILTERS line it doesnt error (but because I need that line it doesnt diplay anything aswell)
但是我认为保存
$content = apply_filters('the_content', $content);
是灯箱崩溃的那个. 这段代码全部在插件文件中.有谁知道为什么上面的代码会生成并导致500次崩溃?
is the one that the lightbox crashes on. This code is all inside the plugin files. Does anyone know why the above code generates and 500 crash?
希望有人可以帮助我！
整个代码:
if($_REQUEST['popup']!=''){
$postObj = $_POST['pid'];
$content_post = get_post($$postObj);
$content = $content_post->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
echo $content;

推荐答案
您是否检查过Apache/PHP错误日志文件?这对于调试至关重要:)
Have you checked the Apache/PHP error log file? It's essential for debugging :)
我注意到您的代码有2个问题-但更正它们实际上并不能解决500个问题.
I noticed 2 issues with your code - but correcting them might not actually fix the 500.
以下几行没有达到您的预期目的:
These few lines aren't doing what you intend:
$postObj = $_POST['pid'];
$content_post = get_post($$postObj);
将$_POST['pid']更改为$_REQUEST['pid']. pid查询变量未发布.
Change $_POST['pid'] to $_REQUEST['pid']. The pid query variable isn't being POSTed.
将$$postObj更改为$postObj.想象$_REQUEST['pid']返回了123(示例帖子ID).调用$$postObj实际上会尝试调用$123；该变量将不存在且无效，因为它以数字开头.
Change $$postObj to $postObj. Imagine $_REQUEST['pid'] returned 123 (a sample post ID). Calling $$postObj would actually try to call $123; that variable would be both non-existent and invalid because it starts with a numeral.
