php - 保存多个附件并检索它们

Question

我有一个简单的 html 表单，用于发送一封电子邮件，其中包含多个附件(最多 5 个)。我正在 phpadmin 中保存电子邮件、地址。现在我也想保存多个附件。 我如何保存多个附件，然后在其他页面上检索然后返回。

我使用phpmailer发送电子邮件和附件，发送附件的循环是:

  $MyUploads = array();
  foreach(array_keys($_FILES['attach']['name']) as $key) 
{  
$filesize = $_FILES['attach']['size'][$key];
$extention = pathinfo ($_FILES['attach']['name'][$key] ,PATHINFO_EXTENSION );
$name=$_FILES['attach']['name'][$key];
    $filePath = $Location . $name;
    $tmpName = $_FILES['attach']['tmp_name'][$key];


if(move_uploaded_file($tmpName, $filePath))
    {$MyUploads[] = $Location;}
     else
    {$MyUploads[]='';}
     print_r($MyUploads);


$source = $_FILES['attach']['tmp_name'][$key];
$filename = $_FILES['attach']['name'][$key];
$mail->AddAttachment($source, $filename);

}

将这些文件位置插入数据库的查询是

$insert = "INSERT INTO upload (name, type, size, file1, file2, file3, file4, file5,
    created) VALUES  
            ( 
            '".$name."',  
            '".$extention."',  
            '".$filesize."',  
            '".$MyUploads[0]."',  
            '".$MyUploads[1]."',  
            '".$MyUploads[2]."',  
            '".$MyUploads[3]."',
    '".$MyUploads[4]."' ,
    now() 
            )"; 
      $result = $dbLink->query($insert);

现在请问我如何在另一个 php 页面上检索这些文件。请，我是初学者，所以有教程。

我认为你的 table 应该是什么样的

CREATE TABLE IF NOT EXISTS `upload` (
  `uploadID` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `uploadExt` varchar(10) NOT NULL,
  `uploadSize` varchar(50) NOT NULL,
  `uploadPath` varchar(200) NOT NULL,
  `uploadName` varchar(100) NOT NULL,
  PRIMARY KEY (`uploadID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

如何插入

$mysql = new mysqli("localhost","root","","test");
$sql = "INSERT INTO `upload` (
`uploadID` ,
`uploadExt` ,
`uploadSize` ,
`uploadPath` ,
`uploadName`
)
VALUES (
NULL ,  '%s',  '%s',  '%s',  '%s');"


foreach($image_you_have_uploaded as $valid) /// Am sure you know what this is 
{
    //Make sure you mysql_real_escape_string everthing 
    $mysql->query(sprintf($sql,$extention,$filesize,$filePath,$name));
} 

如何获取图片

$sql = "SELECT * FROM upload WHERE uploadName = '%s'" ;
$result = $mysql->query(sprintf($sql,mysql_real_escape_string($name)));

var_dump($result->fetch_assoc())// Output Result

谢谢。
