Given an h-entry, returns author info as well as truncated post text suitable for display.
Install via composer:
{
"indieweb/comments": "0.1.*",
}Or just require the one file:
require_once('src/indieweb/comments.php');The function accepts a PHP array in the format returned by the microformats2 parser and returns a new array that looks like the following:
Original HTML:
<div class="h-entry">
<div class="p-author h-card">
<img src="http://aaronparecki.com/images/aaronpk.png" class="u-photo">
<a href="http://aaronparecki.com">Aaron Parecki</a>
</div>
<h3 class="p-name">Example Note</h3>
<p class="e-content">this text is displayed as the comment</p>
<time class="dt-published" datetime="2014-02-16T18:48:17-0800">Feb 16, 6:48pm</time>
<a href="http://caseorganic.com/post/1" class="u-in-reply-to">in reply to caseorganic.com</a>

}Parse for comment display:
$result = IndieWeb\comments\parse($input, $refURL, $maxLength, $maxLines);Resulting PHP array:
$result = array(
'type' => 'reply',
'author' => array(
'name' => 'Aaron Parecki',
'photo' => 'http://aaronparecki.com/images/aaronpk.png',
'url' => 'http://aaronparecki.com/'
),
'published' => '2014-02-16T18:48:17-0800',
'name' => 'Example Note',
'text' => 'this text is displayed as the comment',
'url' => 'http://aaronparecki.com/post/1'
)This function will return an array with all of the keys above. One or more values may be empty depending on what information was available in the post, such as author name/photo.
The text property will always be within your maximum desired length as passed to the parse() function.
The function follows the algorithm described at comments-presentation
for deciding whether to show the p-name, p-summary or e-content properties and truncating appropriately.
The parser also attempts to determine what type of post this is relative to the primary URL.
A key named type will always be returned with one of the following values:
- mention - default
- reply - when the post contains explicit
in-reply-tomarkup - rsvp - if the post contains an RSVP yes/no/maybe value
- like
- repost
When the type is "rsvp", there will also be an rsvp key set to the value of the RSVP, usually "yes", "no" or "maybe".
If the post has a "name" property that is not the same as the content, then it will also be included in the parsed result. This is so that the calling code can choose to display the post name linked to the full post rather than the content.
$result = array(
'type' => 'mention',
'author' => array(
'name' => 'Aaron Parecki',
'photo' => 'http://aaronparecki.com/images/aaronpk.png',
'url' => 'http://aaronparecki.com/'
),
'published' => '2014-02-16T18:48:17-0800',
'name' => 'Post Name',
'text' => 'this is the text of the article',
'url' => 'http://aaronparecki.com/post/1'
)Please see the tests for more complete examples of parsing different posts.
