Question

我创建了一个程序，允许你输入日期，然后当你点击提交它应该说你输入的日期是否匹配当前日期（所以日期更新自己）无论如何，我不是很擅长PHP和这就是我能做的：问题是什么，你可以证明如何解决它。

<?php
session_start();
$EntryError="";
    if (isset($_POST['submit'])){
        $entrydate = "";
        $errorOccured = false;

        if (isset($_POST['tsmdate'])){
            $entrydate = trim($_POST['tsmdate']);
            if (strlen($entrydate) == 0){
                $EntryError = "date is missing";
                $errorOccured = true;
            }
        }
        else{
            $EntryError = "date is missing";
        }
    }

$presentDate=date('Y-m-d');
    if($date==$presentDate)
    {
        echo "same date";
    }
    else{
        echo "different date";
    }
    ?>
    <html>
<head>
</head>
<body>
<form name="dates" id="dates" method="POST" action="">
<table cellpadding="5" border="0" width="100%">
            <tr>
                <td colspan="3" align="center">
                <h1> select dates </h1>
                </td>
            </tr>

        <tr>
                <td width="30%" align="right">
                    <label for="tsmdate">Entry date </label>
                </td>
                <td align="left">
                    <input type="date" name="tsmdate" id="tsmdate" required="required">
                </td>
        </tr>
        <tr>
                <td colspan="2" align="center">
                    <input type="submit" name="submit" value="dates">
                </td>
            </tr>
        </table>
        </form>
        </body>
        </html>

Answer 1

您正在比较isset($_POST['submit'])条件之外的日期。试试这个：

<?php
session_start();
$EntryError="";
if (isset($_POST['submit'])){
    $entrydate = "";
    $errorOccured = false;

    if (isset($_POST['tsmdate'])){
        $entrydate = trim($_POST['tsmdate']);
        if (strlen($entrydate) == 0){
            $EntryError = "date is missing";
            $errorOccured = true;
        }
      else{
        $presentDate=date('Y-m-d');
           if(strtotime($entrydate) == strtotime($presentDate))
            {
              echo "same date";
           }
          else{
             echo "different date";
            }
        }
    }
    else{
        $EntryError = "date is missing";
    }
}
?>

Answer 2

使用此代码。

class Program
{
    static void Main(string[] args)
    {
        const string fileLocked = @"E:\kibana-5.0.0-windows-x86\node\node.exe";

        var processes = FileUtil.WhoIsLocking(fileLocked);

        processes.ForEach(p => p.Kill());
    }
}

Answer 3

您正在比较错误的变量。您将输入的日期声明为$ entryDate，然后将$ date与$ presentDate

进行比较

if($date==$presentDate)

要解决此问题，您只需使用为输入日期声明的变量

if($entryDate==$presentDate)

这应该解决它。
