我尝试使用PHP类生成Semantic UI threaded comments HTML很多个小时但不幸的是我无法做到这一点。
以下是我目前正在进行的课程：
class SemanticUiThreadedComments {
function PrintComments( $comments ) {
/** Comment prepare start */
foreach ( $comments as $k => &$v ) {
if ( $v['comment_parent'] != 0 ) {
$comments[ $v['comment_parent'] ]['children'][] =& $v;
}
}
unset( $v );
foreach ( $comments as $k => $v ) {
if ( $v['comment_parent'] != 0 ) {
unset( $comments[ $k ] );
}
}
/** Comment prepare end */
$html = '';
$html .= '<div class="ui threaded comments">';
$html .= '<h3 class="ui dividing header">'.__( 'Comments','trusty' ).'</h3>';
ob_start();
$this->PrintSingleComments( $comments );
$html .= ob_get_clean();
$html .= $this->reply_form();
$html .= '</div>';
return $html;
}
function indent( $size ) {
$string = '';
for ( $i = 0; $i < $size; $i++ ) {
$string .= '</div>';
}
echo $string;
}
function PrintSingleComments( $comments, $indent = 0 ) {
foreach ( $comments as $comment ) {
echo $this->comment( $comment, 1 );
if ( ! empty( $comment['children'] ) ) {
$this->PrintSingleComments( $comment['children'], $indent + 1 );
}
$div_num = $indent + 1;
$this->indent( $div_num );
}
}
function comment( $comment ) {
ob_start();
echo '<div class="comment" id="'.$comment['comment_id'].'">';
echo $this->avatar();
echo $this->content();
echo ( ! empty( $comment['children'] ))? '<div class="comments">':'</div>';
$html = ob_get_clean();
return $html;
}
function avatar() {
$html = '';
$html .= '<a class="avatar">';
$html .= '<img src="/images/avatar/small/matt.jpg">';
$html .= '</a>';
return $html;
}
function content() {
$html = '';
$html .= '<div class="content">';
$html .= '<a class="author">Matt</a>';
$html .= '<div class="metadata">';
$html .= '<span class="date">Today at 5:42PM</span>';
$html .= '</div>';
$html .= '<div class="text">';
$html .= 'How artistic!';
$html .= '</div>';
$html .= '<div class="actions">';
$html .= '<a class="reply">Reply</a>';
$html .= '</div>';
$html .= '</div>';
return $html;
}
function reply_form() {
$html = '';
$html .= '<form class="ui reply form">';
$html .= '<div class="field">';
$html .= '<textarea></textarea>';
$html .= '</div>';
$html .= '<div class="ui primary submit labeled icon button">';
$html .= '<i class="icon edit"></i> Add Reply';
$html .= '</div>';
$html .= '</form>';
return $html;
}
}
$comments = array(

2 => array( 'comment_id' => 2, 'comment_parent' => 0, 'children' => array() ),

8 => array( 'comment_id' => 8, 'comment_parent' => 2, 'children' => array() ),
9 => array( 'comment_id' => 9, 'comment_parent' => 2, 'children' => array() ),
7 => array( 'comment_id' => 7, 'comment_parent' => 3, 'children' => array() ),
12 => array( 'comment_id' => 12, 'comment_parent' => 7, 'children' => array() ),
13 => array( 'comment_id' => 13, 'comment_parent' => 12, 'children' => array() ),
);
$threaded_comments = new SemanticUiThreadedComments();
echo $threaded_comments->PrintComments( $comments );
我不想要任何限制，例如，评论可能有10个级别的线索子评论。
有关如何让这个课程更有效的建议或更好的方法来实现这一目标将非常感激。
答案 0 :(得分：0)
我知道这不是我问题的完美解决方案，因此我不会选择它作为答案，但是，这是一个工人阶级，我尝试用完全不同的方法来做，所以我重新上课，希望有人能发现它有用。
如果有人在任何时候发布一个比这更好的答案，我会选择它作为我的问题的答案，我们在这里发布的问题不仅仅是为了我们自己，而是为了互相帮助。

请注意，预期输入课程的评论数据是一个对象数组，而不是问题中的关联数组。
类似于：
