打开 \include\extend.func.php 在最下面加入这个方法

								
												01
											
												function Getimgurls($aid,$num=4)    
										
												02
											
												{
										
												03
											
												    global $dsql;
										
												04
											
												    $imgurls = $result = '';
										
												05
											
												    $imgrow = $dsql->GetOne( "Select imgurls From `mydiy_addonimages` where aid='$aid' ");
										
												06
											
												    $imgurls = $imgrow['imgurls'];
										
												07
											
												    if($imgurls != '')
										
												08
											
												    {
										
												09
											
												        $dtp = new DedeTagParse();
										
												10
											
												        $dtp->LoadSource($imgurls);
										
												11
											
												        $images = array();
										
												12
											
												        if(is_array($dtp->CTags))
										
												13
											
												        {
										
												14
											
												            foreach($dtp->CTags as $ctag)
										
												15
											
												            {
										
												16
											
												                if($ctag->GetName() == 'img')
										
												17
											
												                {
										
												18
											
												                    $row = array();
										
												19
											
												                    $row['width'] = $ctag->GetAtt('width');
										
												20
											
												                    $row['height'] = $ctag->GetAtt('height');
										
												21
											
												                    $row['imgsrc'] = trim($ctag->GetInnerText());
										
												22
											
												                    $row['text'] = $ctag->GetAtt('text');
										
												23
											
												                    $images[] = $row;
										
												24
											
												                }
										
												25
											
												            }
										
												26
											
												        }
										
												27
											
												        $dtp->Clear();
										
												28
											
												        $i = 0;
										
												29
											
												        foreach($images as $row)
										
												30
											
												        {
										
												31
											
												            if($i == $num) break;
										
												32
											
												            if($row['imgsrc'] != '')
										
												33
											
												            {
										
												34
											
												                $result .= "<li><div class='pic'><a title='{$row['text']}' href='{$row['imgsrc']}'><img src='{$row['imgsrc']}' mid='{$row['imgsrc']}' big='{$row['imgsrc']}' width='70' height='70'></a></div></li>";
										
												35
											
												            }
										
												36
											
												            $i++;
										
												37
											
												        }
										
												38
											
												        return $result;
										
												39
											
												    }  
										
												40
											
												}

请注意

												<li><div class='pic'><a title='{$row['text']}' href='{$row['imgsrc']}'><img src='{$row['imgsrc']}' mid='{$row['imgsrc']}' big='{$row['imgsrc']}' width='70' height='70'></a></div></li>

上面这段代码改成符合自己页面的html格式。前台模板中调用代码如下：

												[field:id function=Getimgurls(@me,3)/]

3表示，此篇图集调用三张图片。
