我發現這個類螺紋評論使用PHP和MySQL:獨立的HTML
<?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);
}
}
}
這個曾與此陣:
$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')
);
和結果:
$tc = new Threaded_comments($comment);
$tc->print_comments();
產生以下結果:
Parent
Child
Child Third level
Second Parent
Second Child
這工作正確但是對於defign評論列表(html)我需要將所有html代碼添加到private function format_comment($comment, $depth)
。這是不好的方式,我認爲需要從php class
分開html
。
編輯:(這是我的頁面顯示/打印螺紋評論)
function _comments_($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();
在我的線程頁的評論與format_comment
顯示和工作正確的。萬一我需要使用單獨的PHP類來設計輸出。
在這種情況下,我們如何從類中分離html代碼?
你也對。 MVC的工作很好。但我在項目工作,需要定製這個類。所以我需要從課堂上分離HTML代碼 – NewCod3r
我更新了一些答案。請參閱解決方案1。用你的html創建一個.php模板並將你的數組傳遞給它們。這個模板只包含html和簡單的foreach/if-php。 – schellingerht
