Question

我正在尝试使用PHP更改我上传的文件的名称，我知道这个问题已经得到解答但是我找不到使用别人的例子的解决方案所以请耐心等待。

在下面的代码中，我已将var userid设置为登录的用户。我希望上传的图像接收用户的名称。

<?php

session_start();

//database connectie
include_once('db/conn.php');

if(isset($_SESSION['user'])){ 

    $userid = $_SESSION['user'];
    $ran = $userid;
    $target = "uploads/";
    $target_file = $target . basename($_FILES["fileToUpload"]["name"]);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

    // Check if image file is a actual image or fake image
    if(isset($_POST["submit"])) {
        $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
        if($check !== false) {
            echo "File is an image - " . $check["mime"] . ".";
            $uploadOk = 1;
        } else {
            echo "File is not an image.";
            $uploadOk = 0;
        }
    }
    // Check if file already exists
    if (file_exists($target_file)) {
        echo "Sorry, file already exists.";
        $uploadOk = 0;
    }
    // Check file size
    if ($_FILES["fileToUpload"]["size"] > 5000000) {
        echo "Sorry, your file is too large.";
        $uploadOk = 0;
    }
    // Allow certain file formats
    if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
    && $imageFileType != "gif" ) {
        echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
        $uploadOk = 0;
    }
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
        echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"],$target_file)) {
            echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
        } else {
            echo "Sorry, there was an error uploading your file.";
        }
    }

}else{
    echo "plz login before uploading an image";
}
?>

当您致电move_uploaded_file时，您可以声明图片的去向并更改图片的名称。

//Moves image to 'uploads' and saves image as '$userid.$imageFileType (e.g '31029.png')
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target . $userid . $imageFileType);
