Get Content by ID

Apparently there is no succinct WordPress function for just returning the content of a particular page by the ID of that page. This is that.

function get_the_content_by_id($post_id) {
  $page_data = get_page($post_id);
  if ($page_data) {
    return $page_data->post_content;
  }
  else return false;
}

  1. You might consider changing the title to mention WordPress. I was thinking that you made a new blog post about how to get content of an HTML element by ID, which, ya know, is pretty complicated in and of itself…

  2. echo get_post_field(‘post_content’, $post_id);

  3. If you want the content formatted exactly as the_content() would be (auto paragraphs and curly quotes and so on), line 4 should be:

    return apply_filters('the_content', $page_data->post_content);
  4. Permalink to comment#

    function get_the_content_by_id($post_id) {
    $page_data = get_page($post_id);
    if ($page_data) {
    $content = $page_data->post_content;
    return $content = apply_filters(‘the_content’, $content);
    }
    else return false;
    }

Posting Code

Markdown is supported in the comment area, so you can write inline code in backticks like `this` or multiline blocks of code in in triple backtick fences like ```this```. You don't need to escape code in backticks, Markdown does that for you.

Sadly, it's kind of broken. WordPress only accepts a subset of HTML in comments, which makes sense, because certainly some HTML can't be allowed, like <script> tags. But this stripping happens before the comment is processed by Markdown (via Jetpack). It seems to me that would be reversed, because after Markdown processes code in backticks, it's escaped, thus safe. If you think you can fix this issue, get in touch!

If you need to make sure the code (typically HTML) you post absolutely posts correctly, escape it and put it within <pre><code> tags.
