我在某模型里面增加了一个电话号码的字段tel,希望前台只让具有高级会员权限并且登录的用户才会显示,未登录时显示“请注册后才能显示”。这里用传递参数加SQL实现,具体方法如下:
1、在内容页head之间加上JS:
<script src=http://www.dede58.com/"{dede:global.cfg_cmsurl/}/include/dedeajax2.js" type="text/javascript" ></script>
<script language="javascript">
function CheckLogin_c(){
var taget_obj = document.getElementById('_userlogin_c');
var req = document.getElementById('hid').value;
myajax = new DedeAjax(taget_obj,false,false,'','','');
myajax.SendGet2("{dede:global.cfg_cmspath/}/member/ajax_loginsta_c.php?val="+req);
DedeXHTTP = null;
}
</script>
2、在内容页需要会员限制才能查看的地方添加代码(会员登录前的样子):
<span id="_userlogin_c"><a href=http://www.dede58.com/"/member/index_do.php?fmdo=user&dopost=regnew">请注册后查看!</a></span>
<input type="hidden" value="{dede:field.aid/}" id="hid" />
<script language="javascript" type="text/javascript">CheckLogin_c();</script>
这里获取文章ID的文本框一定要在js之前
3、在/member文件夹中新建一个文件:ajax_loginsta_c.php,添加如下代码(会员登录后的样子):
<?php
require_once(dirname(__FILE__)."/config.php");
AjaxHead();
if($myurl == '')
{
exit('');
}
$uid = $cfg_ml->M_LoginID;
!$cfg_ml->fields['face'] && $face = ($cfg_ml->fields['sex'] == '女')? 'dfgirl' : 'dfboy';
$facepic = empty($face)? $cfg_ml->fields['face'] : $GLOBALS['cfg_memberurl'].'/templets/images/'.$face.'.png';
?>
<?php
$row = $dsql->GetOne(" Select * From `js_addoninfos` where `aid`=$val ");
?>
<?php echo $row['tel']; ?>
