织梦dedecms文章模型整合下载功能

教程实现DEDECMS功能:文章模型整合下载功能,可判断点数,会员组等下载权限,前台可判断是否有附件下载,有则显示,没有则不显示。适用类型:有些文章有下载地址,有些文章没有下载地址的网站。想附件收费的网站等等……具体就不啰嗦了。用得上您就拿走。 
DEDECMS文章模型整合下载功能,可判断点数,会员组等下载权限 

织梦dedecms文章模型整合下载功能


也可以在phpmyadmin中自行添加。 
然后在后台打开核心-频道模型-内容模型管理-普通文章-修改-字段管理,在模型字段配置(文本模式) 里添加 
<field:softlinks itemname="软件地址" type="softlinks" isnull="true" default="" rename="" /> 
<field:daccess islist="1" itemname="下载级别" type="int" isnull="true" default="0" rename="" function="" notsend="1" />   
<field:needmoney islist="1" itemname="需要金币" type="int" isnull="true" default="0" rename="" function="" notsend="1" /> 

如果不添加则会出现无链接信息错误!请务必添加。 
二、数据库字段添加完毕就要修改文章模型的4个文件了。分别是dede管理目录下的article_add.php,article_edit.php和管理模板article_add.htm,article_edit.htm,打开这4个文件依次修改。 
1、修改article_add.htm,在头部的 
<script></script> 
中加入以下代码,
在</script> 
之前加入就行 
var startNum = 0;
function MakeUpload()
{
	var upfield = document.getElementById("uploadfield");
	var endNum =  parseInt(document.form1.picnum.value) + startNum-1;
	if(endNum > 30) endNum = 30;
	for(startNum; startNum<=endNum; startNum++){
		upfield.innerHTML += "<div style='line-height:36px'>软件地址"+startNum+":<input type='text' name='softurl"+startNum+"' style='width:280px' value='http://' />  服务器名称:<input type='text' name='servermsg"+startNum+"' style='width:150px' /></div>
";
	}
}
function ShowHideAddr()
{
	document.getElementById('morelink').style.display = (document.getElementById('morelink').style.display=='block' ? 'none' : 'block');
	document.getElementById('morelink').style.height = '100%';
	document.getElementById('btsh3').value = (document.getElementById('morelink').style.display=='block' ? '隐藏地址' : '显示地址');
}

这个是可以增加下载地址个数的JS代码。 
2、找到
<tr><td colspan="2"><?php PrintAutoFieldsAdd($cInfos['fieldset'],'autofield'); ?></td></tr>

再其后边加入
   <tr><td height="24" bgcolor="#F9FCEF"" class="bline2"><strong> 下载限制:</strong></td></tr>
   <tr>
    <td height="24" class="bline">
     <table width="800" border="0" cellpadding="0" cellspacing="0">
	   <tr>
	   <td width="90" height="30"> 需会员权限:</td>
	   <td width="179" align="left"><select name="daccess" id="daccess" style="width:90px;">
	   <?php 
                $dsql->SetQuery("Select * from `sucai_arcrank` where rank>=0"); 
                $dsql->Execute(); 
                while($row = $dsql->GetArray()) 
                { 
                    if($row['rank']==0) $row['membername'] = "不限会员";
					if($row['rank'] == $softconfig['dfrank']) echo " <option value='{$row['rank']}' selected>{$row['membername']}</option>
"; 
                    else echo "<option value='{$row['rank']}'>{$row['membername']}</option>
"; 
                } 
             ?> </select> </td>
		<td width="120" align="center">需消费金币:</td>
		<td width="411"><input name="needmoney" type="text" id="needmoney" value="<?php echo $softconfig['dfywboy']; ?>" size="8" />个</td>
		</tr>
		<tr>
		<td height="26" colspan="4" style="border-top:1px dashed #8EAF61;">  <span class="STYLE1">(如果设定了下载限制,[<a href="soft_config.php" target="_blank"><u>软件频道设置</u></a>]中“附件下载方式:”必须选择“链接到跳转页面”) </span></td>
		</tr>
	 </table>
	</td>
   </tr>
	<tr>
	<td height="24" bgcolor="#F9FCEF" class="bline2"><strong> 本地软件选择:</strong></td>
	</tr>
	<tr>
	<td height="24" class="bline">
	 <table width="800" border="0" cellspacing="0" cellpadding="0">
	  <tr>
	   <td width="90" height="30"> 本地地址:</td>
	   <td><input name="softurl1" type="text" id="softurl1" size="35" /> <input name="sel1" type="button" id="sel1" value="选取" onclick="SelectSoft('form1.softurl1')" /> 服务器名称: <input name="servermsg1" type="text" id="servermsg1" value="本地下载" style="width:150px;" /> </td>
	  </tr>
	 </table>
	</td>
	</tr>
	<?php 
    if($softconfig['moresitedo'] == 0 && trim($softconfig['sites']) != '') 
    { 
    ?>
	<tr>
	<td height="24" bgcolor="#F9FCEF" class="bline2"><b> 预设的镜像服务器:</b></td>
	</tr>
	<tr class="bline">
	<td style="padding-left:10px;">
    (服务器地址 + 软件地址 = 软件真实地址 [<a href="soft_config.php" target="_blank"><u>软件频道设置</u></a>])<br />
    <?php
    	$sites = explode("
", $softconfig['sites']);
    	$startNum = 2;
    	foreach($sites as $site)
    	{
    		$site = trim($site);
    		if(empty($site)) continue;
    		list($siteurl, $sitename) = explode('|', $site);
    		$siteurl = trim($siteurl);
    		$sitename = trim($sitename);
    ?>
    <?php echo $sitename; ?>:
    <input type='hidden' name='forconfig<?php echo $startNum; ?>' value='1' />
    <input type='text' name='softurlfirst<?php echo $startNum; ?>' style='width:200px' value='<?php echo $siteurl; ?>' /> +
    <input type='text' name='softurl<?php echo $startNum; ?>' style='width:120px' value='' />

		<input type='checkbox' name='need<?php echo $startNum; ?>' class='np' value='1' checked />启用
		<br />
		<?php
		$startNum++;
		}//foreach
		echo "<script language='javascript'>startNum = $startNum;</script>
";
		?>
	  </td>
		</tr>
		<?php 
    }//需要预设镜像 
    ?>
	<tr>
	<td height="24" bgcolor="#F9FCEF" class="bline2"><b> 手动指定地址:</b></td>
	</tr>
	<tr>
	<td height="24" class="bline" style="padding-left:8px;">
	 <table width="800" border="0" cellspacing="0" cellpadding="0" style="margin-bottom:5px;" class="bline">
	  <tr>
	   <td width="90">其它地址:</td>
	   <td><input name="picnum" type="text" id="picnum" size="8" value="5" /> <input name="kkkup" type="button" id="kkkup2" value="增加地址" onclick="MakeUpload();" />   <input type="button" name="Submit3" id="btsh3" value="隐藏地址" onclick="ShowHideAddr();" /> (最多为30个链接)</td>
	  </tr>
	 </table>
	 <div id="morelink" style="display:block;"><div id="uploadfield" style="width:790px;"></div></div>
	 </td>
	</tr>

到这里article_add.htm文件就修改完了。 
3、打开article_edit.htm文件,在头部的 
<script></script> 
中加入以下代码,在</script> 之前加入就行 
var startNum = <?php echo $newRowStart?>;
function MakeUpload()
{
	var upfield = document.getElementById('uploadfield');
	var endNum =  parseInt(document.form1.picnum.value) + startNum;
	if(endNum > 30) endNum = 30;
	for(startNum; startNum < endNum; startNum++)
	{
		upfield.innerHTML += "<div style='line-height:36px'>软件地址"+startNum+":<input type='text' name='softurl"+startNum+"' style='width:280px' value='http://' />  服务器名称:<input type='text' name='servermsg"+startNum+"' style='width:150px' /></div>
";
	}
}

function ShowHideAddr()
{
	document.getElementById('morelink').style.display = (document.getElementById('morelink').style.display=='block' ? 'none' : 'block');
	document.getElementById('btsh3').value = (document.getElementById('morelink').style.display=='block' ? '隐藏地址' : '显示地址');
}

4、找到
<tr><td colspan="2"><?php 
      PrintAutoFieldsEdit($cInfos['fieldset'],$addRow,'autofield'); 
      ?></td></tr>
在其下边加入以下代码:
	<tr><td height="24" class="bline"><table width="800" border="0" cellpadding="0" cellspacing="0"><tr><td width="90" height="30"> 需会员权限:</td><td width="179" align="center"><select name="daccess" id="daccess" style="width:90px;"> <?php 
                $dsql->SetQuery("Select * from `sucai_arcrank` where rank>=0 "); 
                $dsql->Execute(); 
                while($row = $dsql->GetArray()) 
                { 
                    if($row['rank']==0) $row['membername'] = "不限会员"; 
                                    if($row['rank'] == $daccess) echo "     <option value='{$row['rank']}' selected>{$row['membername']}</option>
"; 
                                    else echo "     <option value='{$row['rank']}'>{$row['membername']}</option>
"; 
                } 
             ?> </select> </td><td width="120" align="center">需消费金币:</td><td width="411"><input name="needmoney" type="text" id="needmoney" value="<?php echo $needmoney; ?>" size="8" />个</td></tr><tr><td height="26" colspan="4" style="border-top:1px dashed #8EAF61;">  <span class="STYLE1">(如果设定了下载限制,<a href="soft_config.php" target="_blank"><u>软件频道设置</u></a>中“附件下载方式:”必须选择“链接到跳转页面”) </span></td></tr></table></td></tr><tr><td height="24" colspan="4" bgcolor="#F9FCEF"class="bline2"><strong> 软件链接列表:</strong></td></tr><tr><td height="24" colspan="4" class="bline"><table width="800" border="0" cellspacing="0" cellpadding="0"><tr><td width="72"> 其它地址:</td><td><input name="picnum" type="text" id="picnum" size="8" value="5" /> <input name="kkkup" type="button" id="kkkup2" value="增加数量" onclick="MakeUpload();" />   <input type="button" name="Submit3" id="btsh3" value="隐藏地址" onclick="ShowHideAddr();" /> (最多为30个链接)</td></tr></table></td></tr><tr><td height="24" colspan="4" class="bline" style="padding-left:8px;"><?php 
        echo $nForm; 
          ?><div id="morelink" style="display:block;"><div id="uploadfield" style="width:800px;"></div></div></td></tr>
    <tr>

article_edit.html修改完毕,接下来开始修改article_add.php,要认真看哦! 
5、打开article_add.php,找到 
//保存到附加表 
    $cts = $dsql->GetOne("SELECT addtable FROM `dede_channeltype` WHERE id='$channelid' "); 

在其上边加入 
//软件链接列表 
    $urls = ''; 
  
    //本地链接处理 
    $softurl1 = stripslashes($softurl1); 
    $nsoftsize = ''; 
    if($softurl1 != '') 
    { 
        $urls .= "{dede:link islocal='1' text='{$servermsg1}'} $softurl1 {/dede:link}
"; 
    } 
  
    //其它链接处理 
    for($i=2; $i<=30; $i++) 
    { 
        if(!(${'softurl'.$i})) 
        { 
            $forconfig = (${'forconfig'.$i}) ? FALSE : TRUE; 
            if($forconfig) 
            { 
                if(empty(${'need'.$i})) continue; 
                $serverUrl = stripslashes(${'softurlfirst'.$i}); 
                $serverUrl = preg_replace("#/$#", "", $serverUrl); 
                $softurl = stripslashes(${'softurl'.$i}); 
                if( cn_substr($softurl, 1) != '/' ) $softurl = '/'.$softurl; 
                $softurl = $serverUrl.$softurl; 
            } 
            else 
            { 
                $softurl = stripslashes(${'softurl'.$i}); 
            } 
            $servermsg = str_replace("'", "", stripslashes(${'servermsg'.$i})); 
            if($servermsg=='') $servermsg = '下载地址'.$i; 
            if($softurl != '') 
            { 
                $urls .= "{dede:link text='$servermsg'} $softurl {/dede:link}
"; 
            } 
        } 
    } 
    $urls = addslashes($urls); 

这段大概在203行左右,主要作用是处理下载地址。然后再找到 
$query = "INSERT INTO `{$addtable}`(aid,typeid,redirecturl,templet,userip,body{$inadd_f}) Values('$arcID','$typeid','$redirecturl','$templet','$useip','$body'{$inadd_v})"; 

替换为 
$query = "INSERT INTO `{$addtable}`(aid,typeid,redirecturl,templet,userip,body,softlinks,needmoney,daccess{$inadd_f}) Values('$arcID','$typeid','$redirecturl','$templet','$useip','$body','$urls','$needmoney','$daccess'{$inadd_v})";

article_add.php修改完毕,添加一下文章,把下载地址,金币,会员组都写进去,看看数据库是不是有这条记录了^ ^。 
6、打开article_edit.php,找到 
$channelid = $arcRow['channel']; 

在其上边加入 
    $newRowStart = 1;
    $nForm = '';
    $daccess = $addRow['daccess'];
    $needmoney = $addRow['needmoney'];
    if($addRow['softlinks'] != '')
    {
        $dtp = new DedeTagParse();
        $dtp->LoadSource($addRow['softlinks']);
        if(is_array($dtp->CTags))
        {
            foreach($dtp->CTags as $ctag)
            {
                if($ctag->GetName()=='link')
                {
                    $islocal = $ctag->GetAtt('islocal');
                    if($islocal != 1) $needmsg = "<input type='checkbox' name='del{$newRowStart}' value='1' />删除";
                    else $needmsg = '<input name="sel1" type="button" id="sel1" value="选取" onClick="SelectSoft('form1.softurl'.$newRowStart.'')" />';
                    $nForm .= "<div style='line-height:36px'>软件地址{$newRowStart}:<input type='text' name='softurl{$newRowStart}' style='width:280px' value='".trim($ctag->GetInnerText())."' />
            服务器名称:<input type='text' name='servermsg{$newRowStart}' value='".$ctag->GetAtt("text")."' style='width:150px' />
            <input type='hidden' name='islocal{$newRowStart}' value='{$islocal}' />
            $needmsg
            </div>
";
                    $newRowStart++;
                }
            }
        }
        $dtp->Clear();
    }

找到 
$cts = $dsql->GetOne("SELECT addtable FROM `dede_channeltype` WHERE id='$channelid' "); 

在其上边加入以下代码: 
//软件链接列表 
    $urls = ''; 
     
    for($i=1; $i<=30; $i++) 
    { 
        if(!empty(${'softurl'.$i})) 
        { 
            $islocal = empty(${'islocal'.$i}) ? '' : 1; 
            $isneed = empty(${'del'.$i}) ? true : false; 
            $servermsg = str_replace("'",'',stripslashes(${'servermsg'.$i})); 
            $softurl = stripslashes(${'softurl'.$i}); 
             
            if($servermsg=='') 
            { 
                $servermsg = '下载地址'.$i; 
            } 
            if($softurl != '') 
            { 
                if($islocal==1) $urls .= "{dede:link islocal='$islocal' text='{$servermsg}'} $softurl {/dede:link}
" ; 
                else if($isneed) $urls .= "{dede:link text='$servermsg'} $softurl {/dede:link}
"; 
                else continue; 
            } 
        } 
    } 
    $urls = addslashes($urls);     

找到 
$iquery = "UPDATE `$addtable` SET typeid='$typeid',body='$body'{$inadd_f},redirecturl='$redirecturl',templet='$templet',userip='$useip' WHERE aid='$id'"; 

替换为: 
$iquery = "UPDATE `$addtable` SET typeid='$typeid',body='$body'{$inadd_f},redirecturl='$redirecturl',templet='$templet',userip='$useip',softlinks ='$urls',needmoney = '$needmoney',daccess = '$daccess' WHERE aid='$id'"; 

至此本教程后台修改部分已经完毕,你学会了吗?接下来开始前台部分。 
三、前台调用,和软件的前台调用方式一样,看以下代码 
{dede:field name='softlinks'/} 

这个就是调用下载地址,打开的页面为软件模型的下载页,在哪里可以判断到下载的权限。这里就不多讲了,改完后就可以看到了。 
有一种情况,就是有些网友希望没有下载地址的话就不显示,这里可以提供一种方法。把如下代码复制到文章模板里即可。 
{dede:php} 
        $thisid = $refObj->Fields['aid']; 
        $totrow=$dsql->GetOne('select * from dede_addonarticle where aid='.$thisid); 
        if($totrow['softlinks']!='') 
        { 
        echo "<a href="/plus/download.php?open=0&aid=".$thisid."&cid=1" style="color:white" target="_blank">下载地址</a>"; 
        } 
{/dede:php}

	 {dede:field.softlinks runphp='yes'}
	 if(@me =='')
	 {@me='';}
	 else
	 {@me=@me;}
	 {/dede:field.softlinks}

 {dede:field name='softlinks' runphp='yes'} if(@me == "") @me = "style='display:none'";else @me = "@me"; {/dede:field}
到这里,本教程全文完毕。
