<form action="javascript:;" enctype="multipart/form-data" method="post"> ???????????<input type="hidden" name="action" value="post" /> ???????????<input type="hidden" name="diyid" value="1" /> ???????????<input type="hidden" name="do" value="2" /> ???????????<label>姓名：<input type="text" id="name" name="name" value="" /></label> ???????????<label>电话：<input type="text" id="tel" name="tel" value="" /></label> ???????????<label>手机：<input type="text" id="iphone" name="iphone" value="" /></label> ???????????<label>邮箱：<input type="text" id="email" name="email" value="" /></label> ???????????<table> ?????????????<tr> ???????????????<td valign="top">留言：</td> ???????????????<td><textarea id="liuyan" name="liuyan"></textarea></td> ?????????????</tr> ???????????</table> ???????????<input type="hidden" name="dede_fields" value="name,textchar;tel,textchar;iphone,textchar;email,textchar;liuyan,multitext" /> ???<input type="button" class="submit fr" value="提 交" onclick="add_ajaxmessage()"/></form>

/*将此函数绑定到form提交的onclick上*/function add_ajaxmessage(){
 ???/*获取对应元素的val值*/ ???var name=document.getElementById("name"); ???var tel ???=document.getElementById("tel"); ???var iphone=document.getElementById("iphone"); ???var email=document.getElementById("email"); ???var liuyan=document.getElementById("liuyan"); ???//定义变量接收上面表单每项的值和几个dede隐藏的input的值 ???var dataString = ‘name=‘+ name.value + ‘&tel=‘ + tel.value + ‘&iphone=‘ + iphone.value + ‘&email=‘ + email.value + ‘&liuyan=‘+ liuyan.value +‘&action=post‘+ ‘&diyid=1&do=2&dede_fields=name,textchar;tel,textchar;iphone,textchar;email,textchar;liuyan,multitext‘; ???$.ajax({ ???????type: "POST", ???????url: "/plus/diy.php", //提交到后台文件 ???????data: dataString, //传值 ???????success: function(data) { ???????????alert(data);//成功打印PHP返回的值 ???????} ???}); ???return false;}

找到：if(!empty($dede_fields)){ ???//在里面加入判断语句,不判断也可以 ???if($name==""){ ???????????echo "请填写您的姓名！";//注意：输出用echo输出，不要用showMsg()； ???????exit(); ???}}找到：$goto = !empty($cfg_cmspath) ? $cfg_cmspath : ‘/‘; ?????$bkmsg = ‘发布成功，请等待管理员处理...‘;这两句，改成：echo "提交成功！";删掉下面这一句：showmsg($bkmsg, $goto);
