Question

我想知道如何在上传文件时彻底更改名称。我有一个文本输入“名称”，所以我试图把$ _POST ['name']放到moveuploadedfile函数，但没有结果。我应该把它放在哪里？

html

<form id="upload" enctype="multipart/form-data" action="upload.php"method="post">

        <input type="text" name="name" placeholder="name" />
        <input type="text" name="watermark" placeholder="watermakr" />
        <input type="file" name="file" /><br />
        <input type="submit" value="send" />
</form>

PHP

$uploads_dir ='/usr/local/apache/htdocs/images/';
$target_file = $uploads_dir . basename($_FILES["file"]["name"]);

$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);


// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg") {
echo "Only JPG, JPEG, PNG files are allowed.";
$uploadOk = 0;
}



if ($uploadOk == 0) {
echo "ERROR";
// if everything is ok, try to upload file
}
else {


if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {



    echo "File". basename( $_FILES["file"]["name"]). " was sent.";

Answer 1

旧行：

move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)

新行：

move_uploaded_file($_FILES["file"]["tmp_name"], $uploads_dir . $_POST['name'])

Answer 2

而不是

if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {
    echo "File". basename( $_FILES["file"]["name"]). " was sent.";

使用

    $ext = last(explode('.', $_FILES['file']['tmp_name']));
    $custom_name = 'something'; // or $_POST['name']
    $imageName = $custom_name.'.'.$ext;
    move_uploaded_file($_FILES["file"]["tmp_name"], $uploads_dir . $imageName);

用你自己的名字上传php
