dede自定义表单必填项的方法

1. 在plus/diy.php 的第40行下加

//增加必填字段判断
if($required!=''){
if(preg_match('/,/', $required))
{
$requireds= explode(',',$required);
foreach($requiredsas $field){
if($$field==''){
showMsg('带*号的为必填内容，请正确填写','-1');
exit();
}
}
}else{
if($required==''){
showMsg('带*号的为必填内容，请正确填写','-1');
exit();
}
}
}
//end

2.在模版的表单里加 <inputtype="hidden" name="required" value="name,qq"/>
value 就是必须字段 多个用, 隔开。

案例分享：

<form action="/plus/diy.php"enctype="multipart/form-data" method="post">
<input type="hidden"name="required" value="name,qq" />
<input type="hidden" name="action" value="post"/>
<input type="hidden" name="diyid" value="1"/>
<input type="hidden" name="do" value="2"/>
<table style="width:97%;" cellpadding="0"cellspacing="1">
