WordPress 的 PHP 函数

我在 WordPress 中有这个 php 函数，

function includePosts ($content = '') { 
    preg_match_all('/(?<=\\[\\[)\\d+?(?=\\]\\])/', $content, $matches, PREG_PATTERN_ORDER);
    $numMatches = count($matches[0]);
    for ($i = 0; $i < $numMatches; $i++) {
        $postId = $matches[0][$i];
        $post= get_post($postId);
        $linkToPost = '<a href="'.get_permalink($postId).'">';  
        $postTitle = $post->post_title;
        $postTitleText = "<li> $linkToPost$postTitle</a></li>";
        $content = str_replace("[[$postId]]", $postTitleText, $content);
    }
    return $content;
}
//  add_action('admin_menu', 'addAdminPage');
add_filter('the_content', 'includePosts', 1);

它的作用是从 WordPress 页面获取短代码，这将是一个帖子 ID，并在

..

一切都好..但也不完全是。我想要所有的

; ... ... 内的

。这个功能可以实现吗？

jeremysawesome，我忘记提到的一件事 return $content 不仅返回

而且还返回短代码所在页面的内容，但是谢谢您时间。

三星网页设计，你的解决方案表现得很奇怪，我得到这样的信息：

<ul>

   <li>...</li>

   <li>...</li>

      <ul>

        <li>...</li>

        <li>...</li>

     </ul>
</ul>

我真的不明白

I have this php function in wordpress

function includePosts ($content = '') { 
    preg_match_all('/(?<=\\[\\[)\\d+?(?=\\]\\])/', $content, $matches, PREG_PATTERN_ORDER);
    $numMatches = count($matches[0]);
    for ($i = 0; $i < $numMatches; $i++) {
        $postId = $matches[0][$i];
        $post= get_post($postId);
        $linkToPost = '<a href="'.get_permalink($postId).'">';  
        $postTitle = $post->post_title;
        $postTitleText = "<li> $linkToPost$postTitle</a></li>";
        $content = str_replace("[[$postId]]", $postTitleText, $content);
    }
    return $content;
}
//  add_action('admin_menu', 'addAdminPage');
add_filter('the_content', 'includePosts', 1);

What this does is to bring the shortcode from the wordpress page, wich would be a post id and displays the title of that post between <li>..<li> Everything ok .. well not quite.
I want all the <li> ... </li> inside one <ul>...</ul>. Is it posible in this function?

jeremysawesome, one thing i forgot to mention return $content returns not only the <li> but also the content of the page where the shortcode is, but thank you for your time.

Tristar Web Design, your solution acts strange, I get something like this:

<ul>

   <li>...</li>

   <li>...</li>

      <ul>

        <li>...</li>

        <li>...</li>

     </ul>
</ul>

I really don't get it

只是在黑暗中开枪。如果您将 return 语句替换为下面的语句，它是否可以实现您想要的效果？

return "<ul>$content</ul>";

Just a shot in the dark. If you replace your return statement with the one below, does it accomplish what you would like?

return "<ul>$content</ul>";

像这样的东西可能会起作用：

function includePosts ($content = '') { 
    preg_match_all('/(?<=\\[\\[)\\d+?(?=\\]\\])/', $content, $matches, PREG_PATTERN_ORDER);
    $numMatches = count($matches[0]);
    for ($i = 0; $i < $numMatches; $i++) {
        $postId = $matches[0][$i];
        $post= get_post($postId);
        $linkToPost = '<a href="'.get_permalink($postId).'">';  
        $postTitle = $post->post_title;
        $ul = ($i == 0) ? '<ul>' : '';
        $endul = ($i == $numMatches) ? '</ul>' : '';
        $postTitleText = "$ul<li> $linkToPost$postTitle</a></li>$endul";
        $content = str_replace("[[$postId]]", $postTitleText, $content);
    }
    return $content;
}
//  add_action('admin_menu', 'addAdminPage');
add_filter('the_content', 'includePosts', 1);

不能 100% 确定这会起作用，但尝试一下！

Something like this might work:

function includePosts ($content = '') { 
    preg_match_all('/(?<=\\[\\[)\\d+?(?=\\]\\])/', $content, $matches, PREG_PATTERN_ORDER);
    $numMatches = count($matches[0]);
    for ($i = 0; $i < $numMatches; $i++) {
        $postId = $matches[0][$i];
        $post= get_post($postId);
        $linkToPost = '<a href="'.get_permalink($postId).'">';  
        $postTitle = $post->post_title;
        $ul = ($i == 0) ? '<ul>' : '';
        $endul = ($i == $numMatches) ? '</ul>' : '';
        $postTitleText = "$ul<li> $linkToPost$postTitle</a></li>$endul";
        $content = str_replace("[[$postId]]", $postTitleText, $content);
    }
    return $content;
}
//  add_action('admin_menu', 'addAdminPage');
add_filter('the_content', 'includePosts', 1);

Not 100% sure this will work, but give it a try!
