dedecms添加自定义表单判断表单不能为空解决办法

来源：互联网发布：数据库查看器编辑：程序博客网时间：2024/05/16 08:22

今天在做一个在线提交订单的时候，遇到一个问题，就是添加判断语句，当自定义表单里面为空的时候，提示，提交失败，找了半天，解决办法很简单，简单两步。

直入正题：

第一步：

修改网站程序程序文件：plus/diy.php 查找：

$dede_fields = empty($dede_fields) ? '' : trim($dede_fields);

第二步：

一般在代码40行附近，在下面增加如下代码：

//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

注*：禁止了本站的复制功能，请各位童鞋手动敲代码进去，注意全半角字符，因为复制的代码很容易出错。

修改完成后返回到表单页面，在表单中加入：

上面代码中：xiaofannm,xiaofanemail,xiaofanseo，3个value是自定义表单中的数据字段名，你想要哪个字段必填就填写哪个字段。

最后保存重新生成表单页面就可以了。
