如何设置脚本输入表单的最小大小字符？

Question

这里我有这样的调用字段，所以我必须提到验证，我该怎么做？现在没有验证，但我想制作最小字符8 ??

[ "note", {"label":" Reason why not apply leave before taken","type":"textarea","validation":"none"}]

我有一个文件，文本，文本区域，日期，日期时间等....

以下电子邮件的样本验证

[ "work_email", {"label":"Work Email","type":"text","validation":"email"}],

Answer 1

您可以使用HTML5的验证。等，

＆＃13;

＆＃13;

<form method="POST" action="#">
<input pattern=".{8,}" required="required"> <!-- required attribute will make the text box not empty check and pattern attribute is checking for Minimum 8 character -->
  <input type="submit" value="Check">
  </form>

＆＃13;

＆＃13;

＆＃13;

希望这能解决您的问题。

在我使用的php文件中

if(strlen($req->note) < 6){
            return new IceResponse(IceResponse::ERROR,"Please provide the correct reason");
        }
