DZ触摸屏版贴子列表页修改方法
模板文件位置/template/default/touch/forum/forumdisplay.htm
如果使用得不是默认模板，位置为/template/自定义模板名文件夹名/touch/forum/forumdisplay.htm

修改参看DZ数据表字典
 discuz列表页调用帖子内容（正文）
实际使用下面实例时，去掉代码中双正斜杠“//”的注释内容。

DZ触摸屏版贴子列表页调用一张附件图片

如果有则调用，如果没有则不调用

{if $thread['attachment'] == 2}
{eval $table='forum_attachment_'.substr($thread['tid'], -1);}
{eval $thread['aid'] = DB::result_first("SELECT aid FROM ".DB::table($table)." WHERE tid='$thread[tid]' AND isimage!='0'");}
{/if}
//以下三种形式，前面必须有以上的几行代码，或者用自己的方法把它们结合到一起
//形式一
{if $thread['aid']}
<img alt="" src="{eval echo(getforumimg($thread['aid'],1,120,120))}" />
{/if}
//形式二
{if $thread['aid']}
<img alt="" src="{eval echo(getforumimg($thread['aid']))}" />
{/if}
//形式三
{if $thread['aid']}
{eval $abc=getforumimg($thread['aid'])}
<img src="$abc" alt="" />
{/if}

{if $thread['attachment'] == 2}

{eval $table='forum_attachment_'.substr($thread['tid'], -1);}

{eval $thread['aid'] = DB::result_first("SELECT aid FROM ".DB::table($table)." WHERE tid='$thread[tid]' AND isimage!='0'");}

{/if}

//以下三种形式，前面必须有以上的几行代码，或者用自己的方法把它们结合到一起

//形式一

{if $thread['aid']}

{/if}

//形式二

{if $thread['aid']}

{/if}

//形式三

{if $thread['aid']}

{eval $abc=getforumimg($thread['aid'])}

{/if}

DZ触摸屏版贴子列表页调用所有（多张）附件图片

{if $thread['attachment'] == 2}
{eval $table='forum_attachment_'.substr($thread['tid'], -1);}
{eval $thread['attachmentimg'] = DB::fetch_all("SELECT * FROM ".DB::table($table)." WHERE tid='$thread[tid]' AND isimage!='0'");}
{loop $thread['attachmentimg'] $keyimg $valimg}
<a class="attachmentimg attachmentimg_$i" href="data/attachment/forum/$valimg['attachment']"><img src="data/attachment/forum/$valimg['attachment']" /></a>
{/loop}
{/if}

{if $thread['attachment'] == 2}

{eval $table='forum_attachment_'.substr($thread['tid'], -1);}

{eval $thread['attachmentimg'] = DB::fetch_all("SELECT * FROM ".DB::table($table)." WHERE tid='$thread[tid]' AND isimage!='0'");}

{loop $thread['attachmentimg'] $keyimg $valimg}

{/loop}

{/if}

解释如下：
表pre_forum_thread中字段attachment，附件类型,0无附件 1普通附件 2有图片附件
{if $thread['attachment'] == 2} //如果此贴字段attachment等于2时
$table等于forum_attachment_2
查询数据表pre_forum_attachment_2得到$thread['aid']的新值（调用单张图片的实例中使用的）
查询数据表pre_forum_attachment_2得到数组$thread['attachmentimg']
循环输出数据$thread['attachmentimg']的键和值（$keyimg和$valimg，都为数组）
数据表pre_forum_attachment_2中字段attachment即为图片附件路径
所以图片附件路径为$valimg['attachment']
注：DB::fetch_all很好的东东

discuz列表页调用帖子内容及附件方法

Posted on 2016年1月25日 by 织梦先生

功能：获取主题内容和图片附件

找到文件\source\module\forum\forum_forumdisplay.php

搜索（大约812行）$threadids[$threadindex] = $thread['tid'];

在此代码后增加如下代码：

include_once libfile('function/post');
include_once libfile('function/attachment');
$thread['post'] = C::t('forum_post')->fetch_all_by_tid_position($thread['posttableid'],$thread['tid'],1);
$thread['post'] = array_shift($thread['post']);
$thread['preview'] = messagecutstr($thread['post']['message'], 200);//控制字符
$attachments = C::t('forum_attachment_n')->fetch_all_by_id('tid:'.$thread['post']['tid'], 'pid', $thread['post']['pid']);
$attachs = $imgattachs = array();
foreach(C::t('forum_attachment')->fetch_all_by_id('pid', $thread['post']['pid'], 'aid') as $attach) {
$attach = array_merge($attach, $attachments[$attach['aid']]);
$attach['filenametitle'] = $attach['filename'];
$attach['ext'] = fileext($attach['filename']);
getattach_row($attach, $attachs, $imgattachs);
}
$thread['attachments'] = $imgattachs;

include_once libfile('function/post');

include_once libfile('function/attachment');

$thread['post'] = C::t('forum_post')->fetch_all_by_tid_position($thread['posttableid'],$thread['tid'],1);

$thread['post'] = array_shift($thread['post']);

$thread['preview'] = messagecutstr($thread['post']['message'], 200);//控制字符

$attachments = C::t('forum_attachment_n')->fetch_all_by_id('tid:'.$thread['post']['tid'], 'pid', $thread['post']['pid']);

$attachs = $imgattachs = array();

foreach(C::t('forum_attachment')->fetch_all_by_id('pid', $thread['post']['pid'], 'aid') as $attach) {

$attach = array_merge($attach, $attachments[$attach['aid']]);

$attach['filenametitle'] = $attach['filename'];

$attach['ext'] = fileext($attach['filename']);

getattach_row($attach, $attachs, $imgattachs);

}

$thread['attachments'] = $imgattachs;

修改后截图如下：

调用方法：调用帖子文字内容

<p>$thread['preview']</p>

0	<p>$thread['preview']</p>

调用方法：调用附件图片

{if $thread['attachment'] == 2 && $thread['attachments']['used']}
<p class="attachmentimg">
{loop $thread['attachments']['used'] $keyimg $valimg}
<a class="attachmentimg attachmentimg_$i" href="$valimg['url']/$valimg['attachment']"><img src="$valimg['url']/$valimg['attachment']" width=$valimg['width'] height=$valimg['width'] /></a>
{/loop}
</p>
{/if}

{if $thread['attachment'] == 2 && $thread['attachments']['used']}

{loop $thread['attachments']['used'] $keyimg $valimg}

{/loop}

{/if}

说明：

参看\source\function\function_post.php中的getattach_row函数（在文件的第61行）

首页要确定$thread['attachment'] == 2和数组$thread['attachments']['used']为真，才可以运行以下代码。

循环搜索数组$thread['attachments']['used']

在循环内数组$valimg[]可以调用表pre_forum_attachment_2中的键值（参看：Discuz! X3 数据字典 DZ数据表结构）

php class中对象属性和方法的可见性定义public,private,protected的区别，以及实例

Posted on 2016年1月16日 by 织梦先生

一，public,private,protected的区别

public:权限是最大的，可以内部调用，实例调用等。

protected: 受保护类型，用于本类和继承类调用。

private: 私有类型，只有在本类中使用。

二，实例

<?php
error_reporting(E_ALL);

class test{
 public $public;
 private $private;
 protected $protected;
 static $instance;
 public  function __construct(){
 $this->public    = 'public     <br>';
 $this->private   = 'private    <br>';
 $this->protected = 'protected  <br>';
 }
 static function tank(){
 if (!isset(self::$instance[get_class()]))
 {
 $c = get_class();
 self::$instance = new $c;
 }

 return self::$instance;
 }    

 public function pub_function() {
 echo "you request public function<br>";
 echo $this->public;
 echo $this->private;        //private,内部可以调用
 echo $this->protected;      //protected,内部可以调用
 $this->pri_function();      //private方法，内部可以调用
 $this->pro_function();      //protected方法，内部可以调用
 }
 protected  function pro_function(){
 echo "you request protected function<br>";
 }
 private function pri_function(){
 echo "you request private function<br>";
 }
}

$test = test::tank();
echo $test->public;
echo $test->private;    //Fatal error: Cannot access private property test::$private
echo $test->protected;  //Fatal error: Cannot access protected property test::$protected
$test->pub_function();
$test->pro_function();  //Fatal error: Call to protected method test::pro_function() from context
$test->pri_function();  //Fatal error: Call to private method test::pri_function() from context

?>

<?php

error_reporting(E_ALL);

class test{

public $public;

private $private;

protected $protected;

static $instance;

public function __construct(){

$this->public = 'public ';

$this->private = 'private ';

$this->protected = 'protected ';

}

static function tank(){

if (!isset(self::$instance[get_class()]))

{

$c = get_class();

self::$instance = new $c;

}

return self::$instance;

}

public function pub_function() {

echo "you request public function ";

echo $this->public;

echo $this->private; //private,内部可以调用

echo $this->protected; //protected,内部可以调用

$this->pri_function(); //private方法，内部可以调用

$this->pro_function(); //protected方法，内部可以调用

}

protected function pro_function(){

echo "you request protected function ";

}

private function pri_function(){

echo "you request private function ";

}

$test = test::tank();

echo $test->public;

echo $test->private; //Fatal error: Cannot access private property test::$private

echo $test->protected; //Fatal error: Cannot access protected property test::$protected

$test->pub_function();

$test->pro_function(); //Fatal error: Call to protected method test::pro_function() from context

$test->pri_function(); //Fatal error: Call to private method test::pri_function() from context

从上面的例子中，我们可以看出，
public: 可以class内部调用，可以实例化调用。
private: 可以class内部调用，实例化调用报错。
protected：可以class内部调用，实例化调用报错。

<?php

class test{
 public $public;
 private $private;
 protected $protected;
 static $instance;

 public  function __construct(){
 $this->public    = 'public     <br>';
 $this->private   = 'private    <br>';
 $this->protected = 'protected  <br>';
 }
 protected function tank(){                          //私有方法不能继承，换成public,protected
 if (!isset(self::$instance[get_class()]))
 {
 $c = get_class();
 self::$instance = new $c;
 }
 return self::$instance;
 }    

 public function pub_function() {
 echo "you request public function<br>";
 echo $this->public;
 }
 protected  function pro_function(){
 echo "you request protected function<br>";
 echo $this->protected;
 }
 private function pri_function(){
 echo "you request private function<br>";
 echo $this->private;
 }
}

class test1 extends test{

 public function __construct(){
 parent::tank();
 parent::__construct();
 }
 public function tank(){
 echo $this->public;
 echo $this->private;       //Notice: Undefined property: test1::$private
 echo $this->protected;
 $this->pub_function();
 $this->pro_function();
 $this->pri_function();    //Fatal error: Call to private method test::pri_function() from context 'test1'
 }

 public  function pro_extends_function(){
 echo "you request extends_protected function<br>";
 }
 public function pri_extends_function(){
 echo "you request extends_private function<br>";
 }
}

error_reporting(E_ALL);
$test = new test1();
$test -> tank();       //子类和父类有相同名字的属性和方法，实例化子类时，子类的中的属性和方法会盖掉父类的。

?>

<?php

class test{

public $public;

private $private;

protected $protected;

static $instance;

public function __construct(){

$this->public = 'public ';

$this->private = 'private ';

$this->protected = 'protected ';

}

protected function tank(){ //私有方法不能继承，换成public,protected

if (!isset(self::$instance[get_class()]))

{

$c = get_class();

self::$instance = new $c;

}

return self::$instance;

}

public function pub_function() {

echo "you request public function ";

echo $this->public;

}

protected function pro_function(){

echo "you request protected function ";

echo $this->protected;

}

private function pri_function(){

echo "you request private function ";

echo $this->private;

}

class test1 extends test{

public function __construct(){

parent::tank();

parent::__construct();

}

public function tank(){

echo $this->public;

echo $this->private; //Notice: Undefined property: test1::$private

echo $this->protected;

$this->pub_function();

$this->pro_function();

$this->pri_function(); //Fatal error: Call to private method test::pri_function() from context 'test1'

}

public function pro_extends_function(){

echo "you request extends_protected function ";

}

public function pri_extends_function(){

echo "you request extends_private function ";

}

error_reporting(E_ALL);

$test = new test1();

$test -> tank(); //子类和父类有相同名字的属性和方法，实例化子类时，子类的中的属性和方法会盖掉父类的。

从上面的例子中，我们可以看出，
public:    test中的public可以被继承。
private:   test中的private不可以被继承。
protected： test中的protected可以被继承。
static：        test中的static可以被继承。

唉，对于这些东西，老是不喜欢记着，用的时候，总感觉不对，又要去查，所以写个例子，方便自己查看。
