从php评论类中分离html

New*_*d3r 8 html php mysql

我发现这个类使用php和MySQL进行线程评论:

<?php
class Threaded_comments
{

public $parents  = array();
public $children = array();

/**
 * @param array $comments
 */ 
function __construct($comments)
{
    foreach ($comments as $comment)
    {
        if ($comment['parent_id'] === NULL)
        {
            $this->parents[$comment['id']][] = $comment;
        }
        else
        {
            $this->children[$comment['parent_id']][] = $comment;
        }
    }
}

/**
 * @param array $comment
 * @param int $depth
 */ 
private function format_comment($comment, $depth)
{
    for ($depth; $depth > 0; $depth--)
    {
        echo "\t";
    }

    echo $comment['text'];
    echo "\n";
}

/**
 * @param array $comment
 * @param int $depth
 */ 
private function print_parent($comment, $depth = 0)
{
    foreach ($comment as $c)
    {
        $this->format_comment($c, $depth);

        if (isset($this->children[$c['id']]))
        {
            $this->print_parent($this->children[$c['id']], $depth + 1);
        }
    }
}

public function print_comments()
{
    foreach ($this->parents as $c)
    {
        $this->print_parent($c);
    }
}

}

这适用于这个数组:

$comment = array(  array('id'=>1, 'parent_id'=>NULL,   'text'=>'Parent'),  
                    array('id'=>2, 'parent_id'=>1,      'text'=>'Child'),  
                    array('id'=>3, 'parent_id'=>2,      'text'=>'Child Third level'),  
                    array('id'=>4, 'parent_id'=>NULL,   'text'=>'Second Parent'),  
                    array('id'=>5, 'parent_id'=>4,   'text'=>'Second Child')  
                );

结果:

$tc = new Threaded_comments($comment);
$tc->print_comments();

结果是:

Parent
    Child
        Child Third level
Second Parent
    Second Child

这工作正常但是对于defign评论列表(html)我需要将所有html代码添加到private function format_comment($comment, $depth).这不是好办法,我认为需要单独htmlphp class.

编辑:(这是我的show/print线程评论页面)

function _comments_($id,$type){
    $DB_QUERY = mySqli::f("SELECT id,user,email,message,timestamp,parent_id,rfield_1,rfield_2,rfield_3,rfield_4,rfield_5 FROM " . NEWS_COMMENTS . " LEFT JOIN " . NEWS_REVIEWS . " ON " . NEWS_COMMENTS . ".id = " . NEWS_REVIEWS . ".cid WHERE 
    pid = ? AND type = ? AND approved = 1 ORDER BY timestamp DESC LIMIT 12", $id, $type);

        foreach($DB_QUERY as $row){
         $commentdata[] = $row;
        }
    return $commentdata;
}
$comments_list = _comments_('125','book');
foreach($comments_list as $row){
        $comments[] = array(
        'id' => $row['id'],
        'parent_id' => $row['parent_id'],
        'name' => $row['user'],
        'text' => $row['message'],
        'datetime' => $row['timestamp']
        );
        }

        $tc = new Threaded_comments($comments);
        $tc->print_comments();

在我的页面中,线程评论显示format_comment并且工作正常.以防我需要使用php类中的单独html设计输出.

在这种情况下我们如何从类中分离html代码?!

你说得对。

1)最简单的解决方案是将数组传递给模板。该模板不包含逻辑,仅包含 html 和 php(例如数组的 foreach)。

2)为了更好的分离,使用模型-视图-控制器模式:

MVC简单视图

通过这一层的构建,每一层都有自己的职责。切勿在模型和控制器中使用 html。仅在模型中查询。

Laravel 和 CodeIgniter 等框架都有此模式的实现。
