织梦自定义表单必填项方法

用php验证:  
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($requireds as $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  <input type="hidden" name="required" value="name,qq" />
value  就是必须字段  多个用 , 隔开。
