在 php 中上传时附上文件名的日期和时间

Question

我正在上传一个带有日期时间的文件，但没有发生，这是我的代码：

$time = date('Y-m-d H:i:s');
$filename = $time."-".$filename;
$store = "cvs/".$filename;
move_uploaded_file($tmpfilename, $store);

Answer 1

您的表格应该是这样的：

<form action="" method="post" enctype="multipart/form-data">


   <input type="file" name="myfile" />
   <input type="submit" name="submitbutton" value="Upload" />

  </form>

php 看起来像这样：

<?php

 $time = date("Y-m-d H:i:s");

 $filename = $time."-".$filename ;

 $tmpname = $_FILES['myfile']['tmp_name'];

 move_uploaded_file($tmpname,"cvs/".$filename);

?>

这应该将文件上传到目标 cvs 并在 $filename 中为其指定名称。您将需要为表单添加安全性和验证，我只是总结了答案。

Answer 2

$time = date("d-m-Y")."-".time() ;
$filename = $time."-".$filename ;
$store = "cvs/".$filename ; 
move_uploaded_file($tmpfilename,$store);

`$(document).ready(function(){
    var titArray = [];  
    $('#calPriceTable .custom-check').click(function(event){
        event.stopPropagation();
        var amount = Number($("#totalAmount").text());
        var price = $(this).closest('td').next('td').next('td').next('td').text();
        var title = $(this).closest('td').next('td').text();
        $("#allItem").text("");

        if ($(this).is(':checked')) {
            amount += Number(price);
            titArray.push(title);
        } else {
            alert(price);
            amount -= Number(price);
            for( var i = 0; i < titArray.length; i++){ if ( titArray[i] === title) { titArray.splice(i, 1); i--; }}

        }   
        //alert(amount);
        $("#totalAmount").text(amount.toFixed(2));
        for( var i = 0; i < titArray.length; i++) {
            var str = "<br>"+titArray[i];
            $("#allItem").append(str);
        }


    });

    $('#calPriceTable #customCheckOther').click(function(event){
        if ($(this).is(':checked')) {
            $("#otherDes").removeAttr('disabled');
            $("#otherAmount").removeAttr('disabled');
        } else {
            $("#otherDes").val('').attr('disabled', true);
            $("#otherAmount").val('').attr('disabled', true);
            //$("#otherAmount").removeAttr('disabled');
        }
    });
});`
