我是 PHP 新手。我有一个上传文件并存储在 Mysql 数据库中的代码。我使用 php 创建一个 Web 表单。在这种形式中我使用jquery datepicker。我的问题是，当我运行代码时，它无法正确显示日期。我的代码的结果如下所示:
但是当我在没有 PHP 的情况下使用相同的代码时，它可以正常工作。我不明白这是什么问题？
这是我的代码:
<?php
$host="localhost"; // Host name
$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="test123"; // Database name
//$tbl_name="members"; // Table name
$con=mysql_connect("localhost","root","");
if(! $con)
{
die('Connection Failed'.mysql_error());
}
mysql_select_db("test123",$con);
if(isset($_FILES['files'])){
$errors= array();
foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
$file_name = $key.$_FILES['files']['name'][$key];
$file_size =$_FILES['files']['size'][$key];
$file_tmp =$_FILES['files']['tmp_name'][$key];
$file_type=$_FILES['files']['type'][$key];
if($file_size > 2097152){
$errors[]='File size must be less than 2 MB';
}
$query="INSERT into upload_data (`FILE_NAME`,`FILE_SIZE`,`FILE_TYPE`) VALUES('$file_name','$file_size','$file_type'); ";
$desired_dir="user_data";
//$desired_dir=$options['upload_dir']."user_data";
if(empty($errors)==true){
if(is_dir($desired_dir)==false){
mkdir("$desired_dir", 755); // Create directory if it does not exist
}
if(is_dir("$desired_dir/".$file_name)==false){
move_uploaded_file($file_tmp,"$desired_dir/".$file_name);
}else{ // rename the file if another one exist
$new_dir="$desired_dir/".$file_name.time();
rename($file_tmp,$new_dir) ;
}
mysql_query($query);
}else{
print_r($errors);
}
}
if(empty($error)){
echo "Success";
}
}
?>

最佳答案
我只创建了两个文件，名称为 form.php，第二个文件是 form1.php 现在我的代码运行良好
form1.php
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
