PHP正则表达式日期验证 [英] Php regex date validation

问题描述

我正在尝试使用正则表达式来验证日期输入.

I'm trying to validate a date input by the use of regex.

if(!preg_match("/^[0-9]{4}\/[0-9]{2}\/[0-9]{2}$/", $_POST['variant']['sales_start'])) { 
  echo "invalid";
}

我尝试输入的字符串是 2011-02-03，但是它失败了，我似乎无法弄清楚原因.

The string I'm trying to input is 2011-02-03, however it's failing, and I can't seem to figure out why.

谁能告诉我我做错了什么?

Can someone please tell me what I'm doing wrong?

提前致谢

推荐答案

你用破折号分隔日期而正则表达式寻找斜线?

You're separating the date with dashes and the regex is looking for slashes?

试试

if ( !preg_match( "/^[0-9]{4}-[0-9]{2}-[0-9]{2}$/", $_POST['variant']['sales_start'] ) )
{ 
    echo "invalid";
}
