如何在插入数据库之前重命名图像文件？

数据库名称：项目
表名：image
ields：id（int），文件（varchar）[此处存储的图片网址]，名称（varchar）[图片说明]

HTML代码在这里

<form method="POST" action="signup_process.php" enctype="multipart/form-data">
 Image:  <input type="file" name="user_image">
<input tyoe="submit" value="submit">
 </form>

signup_process.php

 <?php
    include 'dbcon.php';
    $filename = $_FILES[user_image][name];
    $source = $_FILES[customer_photo][tmp_name];
    $destination = "photos/$filename";
    move_uploaded_file($source, $destination);

//sql statement bla bla below to upload file in image table

    ?>

此脚本将文件上传到我的服务器的照片目录中，但我想要的是我想将该名称更改为我的图像表的相应ID。 例如sunshine.jpg - ＆gt; 5.jpg

Answer 1

Please Check below code ,is working for me.

$source = $_FILES[customer_photo][tmp_name];
$temp = explode(".",$_FILES["user_image"]["name"]);
$newfilename = rand(1,99999) . '.' .end($temp); //you can change here random id replace the your id
$destination = "photos/$newfilename";    
move_uploaded_file($source, $destination);

Answer 2

如果您想在将文件名移至其最终位置之前更改文件名，只需更改此行：

$destination = "photos/$filename";

到此：

$path_parts = pathinfo($_FILES["user_image"]["name"]);
$extension = $path_parts['extension'];
$destination = "photos/<the name you want>." . $extension;
