DESTOON会员服务购买和升级改成月付模式

用过destoon的站长都知道，destoon的会员购买和升级模式是按年付费的，有很多用户不愿意一次花很多钱买年费，所以，我们就改成月付模式，但destoon默认不支持月付，没办法，只能搞个小二开了

其实也很简单，修改部分php代码和模板就可以，下面以默认程序和默认模板为例（如果你对应的程序文件和模板有修改过，请对照教程自行修改，记得先备份）

1、修改 /module/member/account.inc.php  ，找到 case 'vip': 

case 'vip':
		$user = userinfo($_username);
		if(!$MG['vip'] || !$MG['fee'] || $user['totime'] < $DT_TIME) dheader('?action=index');
		$auto = 0;
		$auth = isset($auth) ? decrypt($auth, DT_KEY.'CG') : '';
		if($auth && substr($auth, 0, 4) == 'vip|') {
			$auto = $submit = 1;
			$year = intval(substr($auth, 4));
		}
		if($submit) {
			$year = intval($year);
			in_array($year, array(1, 2, 3)) or $year = 1;
			$fee = dround($MG['fee']*$year);
			$fee > 0 or message($L['vip_msg_fee']);
			$fee <= $_money or message($L['money_not_enough']);
			if($fee <= $DT['quick_pay']) $auto = 1;
			if(!$auto) {
				is_payword($_username, $password) or message($L['error_payword']);
			}
			$totime = $user['totime'] + 365*86400*$year;
			money_add($_username, -$fee);
			money_record($_username, -$fee, $L['in_site'], 'system', $L['vip_renew'], lang($L['vip_record'], array($year, timetodate($totime, 3))));
			$db->query("UPDATE {$DT_PRE}company SET totime=$totime WHERe userid=$_userid");
			dmsg($L['vip_msg_success'], '?action=index');
		} else {
		$havedays = ceil(($user['totime'] - $DT_TIME)/86400);
		$todate = timetodate($user['totime'], 3);
			$year = 1;
			if($sum > 1 && $sum < 4) $year = $sum;
			$fee = dround($MG['fee']*$year);
			$head_title = $L['vip_renew'];
		}
	break;

把它换成

case 'vip':
		$user = userinfo($_username);
		if(!$MG['vip'] || !$MG['fee'] || $user['totime'] < $DT_TIME) dheader('?action=index');
		$months = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 24, 36, 48, 60);  //2020.05.02
		$auto = 0;
		$monthsxh = 12;  //2020.05.02
		$auth = isset($auth) ? decrypt($auth, DT_KEY.'CG') : '';
		if($auth && substr($auth, 0, 4) == 'vip|') {
			$auto = $submit = 1;
			//$year = intval(substr($auth, 4));
			$month = intval($tmp[2]);  //2020.05.02
		}
		if($submit) {
			//$year = intval($year);
			//in_array($year, array(1, 2, 3)) or $year = 1;
			//$fee = dround($MG['fee']*$year);
			$month = intval($month);  //2020.05.02
			in_array($month, $months) or $month = 1;  //2020.05.02
			$fee = dround($MG['fee']/$monthsxh*$month);  //2020.05.02
			$fee > 0 or message($L['vip_msg_fee']);
			$fee <= $_money or message($L['money_not_enough']);
			if($fee <= $DT['quick_pay']) $auto = 1;
			if(!$auto) {
				is_payword($_username, $password) or message($L['error_payword']);
			}
			//$totime = $user['totime'] + 365*86400*$year;
			$totime = $user['totime'] + 86400*30*$month;  //2020.05.02
			money_add($_username, -$fee);
			//money_record($_username, -$fee, $L['in_site'], 'system', $L['vip_renew'], lang($L['vip_record'], array($year, timetodate($totime, 3))));
			money_record($_username, -$fee, $L['in_site'], 'system', $L['vip_renew'], lang($L['vip_record'], array($month, timetodate($totime, 3))));  //2020.05.02
			$db->query("UPDATE {$DT_PRE}company SET totime=$totime WHERe userid=$_userid");
			dmsg($L['vip_msg_success'], '?action=index');
		} else {
		$havedays = ceil(($user['totime'] - $DT_TIME)/86400);
		$todate = timetodate($user['totime'], 3);
			//$year = 1;
			//if($sum > 1 && $sum < 4) $year = $sum;
			//$fee = dround($MG['fee']*$year);
			$month = 1;  //2020.05.02
			if($sum > 1 && $sum < 4) $month = $sum;  //2020.05.02
			$fee = dround($MG['fee']*$month);  //2020.05.02
			$head_title = $L['vip_renew'];
		}
	break;

图例：

2、总后台的显示修改

找到 /module/member/admin/template/group_edit.tpl.php   搜索 “收费设置”  把年改成 月

如图：

3、修改升级提交后 后台审核时的到期时间以 月 为单位

找到/module/member/admin/grade.inc.php  搜索 $days = 364; 改成 $days = 30;

如图：

完成这3步，php就修改完成了。

接着修改前端模板部分（我们以默认模板为例）

1、打开 template/default/member/account.htm  找打  服务费用 

<tr>
<td class="tl">服务费用</td>
<td class="tr"><span class="f_red">{$MG[fee]}</span> {$DT[money_unit]}/年</td>
</tr>
<tr>
<td class="tl"><span class="f_red">*</span> 续费年限</td>
<td class="tr">
<select name="year" id="year"$('#money').html(this.value*{$MG[fee]});">
<option value="1"<?php if($year == 1) echo ' selected';?>>1年</option>
<option value="2"<?php if($year == 2) echo ' selected';?>>2年</option>
<option value="3"<?php if($year == 3) echo ' selected';?>>3年</option>
</select>
</td>
</tr>

换成

<tr>
<td class="tl">服务费用</td>
<td class="tr"><span class="f_red">{$MG[fee]}</span> {$DT[money_unit]}/月</td>
</tr>
<tr>
<td class="tl"><span class="f_red">*</span> 续费期限</td>
<td class="tr">
<select name="month" id="month" onchange="$('#money').html(this.value*{$MG[fee]});">
<option value="1"<?php if($month == 1) echo ' selected';?>>1月</option>
<option value="2"<?php if($month == 2) echo ' selected';?>>2月</option>
<option value="3"<?php if($month == 3) echo ' selected';?>>3月</option>
<option value="4"<?php if($month == 4) echo ' selected';?>>4月</option>
<option value="5"<?php if($month == 5) echo ' selected';?>>5月</option>
<option value="6"<?php if($month == 6) echo ' selected';?>>6月</option>
<option value="7"<?php if($month == 7) echo ' selected';?>>7月</option>
<option value="8"<?php if($month == 8) echo ' selected';?>>8月</option>
<option value="9"<?php if($month == 9) echo ' selected';?>>9月</option>
<option value="10"<?php if($month == 10) echo ' selected';?>>10月</option>
<option value="11"<?php if($month == 11) echo ' selected';?>>11月</option>
<option value="12"<?php if($month == 12) echo ' selected';?>>12月</option>
<option value="13"<?php if($month == 24) echo ' selected';?>>24月</option>
<option value="14"<?php if($month == 36) echo ' selected';?>>36月</option>
<option value="15"<?php if($month == 48) echo ' selected';?>>48月</option>
<option value="16"<?php if($month == 60) echo ' selected';?>>60月</option>
</select>
</td>
</tr>

继续找 大约 293行 {elseif $action == 'vip'}

{elseif $action == 'vip'}
function check() {
	var money = $('#year').val()*{$MG[fee]};
	if(money > {$_money}) {
		Go('charge.php?action=pay&reason=vip|'+$('#year').val()+'&amount='+money+'&bank='+$('#bank').val());
		return false;
	}
	if(money > {$DT[quick_pay]}){
		if(Dd('password').value.length < 6) {
			Dmsg('请填写支付密码', 'password');
			return false;
		}
	}
	return true;
}
window.setInterval(
	function() {
		var money = $('#year').val()*{$MG[fee]};
		if(money > {$_money} || {$_money} < 0.01) {
			$('#mymoney').hide();$('#paytype').show();$('#payword').hide();
		} else {
			$('#mymoney').show();$('#paytype').hide();if(money > {$DT[quick_pay]}){$('#payword').show();}
		}
	}, 
500);
{/if}

改成

{elseif $action == 'vip'}
function check() {
	var money = $('#month').val()*{$MG[fee]};
	if(money > {$_money}) {
		Go('charge.php?action=pay&reason=vip|'+$('#month').val()+'&amount='+money+'&bank='+$('#bank').val());
		return false;
	}
	if(money > {$DT[quick_pay]}){
		if(Dd('password').value.length < 6) {
			Dmsg('请填写支付密码', 'password');
			return false;
		}
	}
	return true;
}
window.setInterval(
	function() {
		var money = $('#month').val()*{$MG[fee]};
		if(money > {$_money} || {$_money} < 0.01) {
			$('#mymoney').hide();$('#paytype').show();$('#payword').hide();
		} else {
			$('#mymoney').show();$('#paytype').hide();if(money > {$DT[quick_pay]}){$('#payword').show();}
		}
	},
500);
{/if}

2、打开 template/default/member/grade.htm  找到 收费模式 ，如

<tr align="center">
	<td>收费模式</td>
	{loop $GROUPS $k $v}{if $k > 4}
	<td>{if $v[fee_mode]}<span class="f_red">包年</span>{else}<span class="f_green">免费</span>{/if}</td>
	{/if}{/loop}
	</tr>
 
	<tr align="center">
	<td>年 费</td>
	{loop $GROUPS $k $v}{if $k > 4}
	<td>{if $v[fee]}<span class="f_price">{$DT[money_sign]}<strong>{$v[fee]}</strong>{$DT[money_unit]}/年</span>{else}--{/if}</td>
	{/if}{/loop}
	</tr>

改成

<tr align="center">
	<td>收费模式</td>
	{loop $GROUPS $k $v}{if $k > 4}
	<td>{if $v[fee_mode]}<span class="f_red">包月</span>{else}<span class="f_green">免费</span>{/if}</td>
	{/if}{/loop}
	</tr>
 
	<tr align="center">
	<td>月 费</td>
	{loop $GROUPS $k $v}{if $k > 4}
	<td>{if $v[fee]}<span class="f_price">{$DT[money_sign]}<strong>{$v[fee]}</strong>{$DT[money_unit]}/月</span>{else}--{/if}</td>
	{/if}{/loop}
	</tr>

这样前端，后台就修改完成了 ，自己去体验吧，图为例
