<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
方法一:首先我们要用一段php代码来判断验证必选项.</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
1、我们先在plus/diy.php 文件中的的第40行下加上一下代码:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode5" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
//增加必填字段判断 <br>
if($required!=''){ <br><br>
if(preg_match('/,/', $required)) <br>
{ <br>
$requireds = explode(',',$required); <br>
foreach($requireds as $field){ <br>
if($$field==''){ <br>
showMsg('带*号的为必填内容，请正确填写', '-1'); <br>
exit(); //phpfensi.com <br>
} <br>
} <br>
}else{ <br>
if($required==''){ <br>
showMsg('带*号的为必填内容，请正确填写', '-1'); <br>
exit(); <br>
} <br>
} <br>
} <br>
//end</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>2、保存完成后,在表单页面找到这行代码.</span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode6" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
<form action="/plus/diy.php" enctype="multipart/form-data" method="post" >`````</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
在这行代码之下,加入代码:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode7" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
<input type="hidden" name="required" value="content,name,tel" />````</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
方法二:我最终以另外的方式实现了,在你的表单页面加上一个JQ和一个JS:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode8" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
<script src="js/jquery-1.8.0.js"></p> <p><script src='{dede:global.cfg_templets_skin/}/style/js/js.js' type="text/javascript"></div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
这个js的内容为:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode9" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
<!-- <br>
$(document).ready(function() <br>
{ <br>
//验证 <br>
$('#complain').submit(function () <br>
{ <br>
if($('#yname').val()==""){ <br>
$('#yname').focus(); <br>
alert("姓名不能为空！"); <br>
return false; <br>
} <br>
if($('#qq').val()=="") <br>
{ <br>
$('#qq').focus(); <br>
alert("手机号码不能为空！"); <br>
return false; <br>
} <br>
if($('#tel').val()=="") <br>
{ <br>
$('#tel').focus(); <br>
alert("所选产品不能为空！"); <br>
return false; <br>
} <br>
if($('#dizhi').val()=="") <br>
{ <br>
$('#dizhi').focus(); <br>
alert("地址不能为空！"); <br>
return false; <br>
} <br>
}) <br><br>
}); <br>
--> <br><br>
<input type='text' name='ytel' id='ytel' style='width:250px' class='intxt' value='' />*</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>注:部分为你表单的ID(如果没有请在表单里面添加上)和必填ID.</span>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
