Question

我有上传图片上传表单，我想将图片名称更改为特定名称。

这是我的代码：

<?php

// A list of permitted file extensions
$allowed = array('png', 'jpg', 'gif','zip');

if(isset($_FILES['upl']) && $_FILES['upl']['error'] == 0){

$extension = pathinfo($_FILES['upl']['name'], PATHINFO_EXTENSION);

if(!in_array(strtolower($extension), $allowed)){
    echo '{"status":"error"}';
    exit;
}

if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/'.$_FILES['upl']['name'])){
    echo '{"status":"success"}';
    exit;
}
}

echo '{"status":"error"}';
exit;

Answer 1

if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/your_own_name_here.'$extension)){
    echo '{"status":"success"}';
    exit;
}

Answer 2

您应该在以下代码中更改 $ _ FILES ['upl'] ['name']

if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/'.$_FILES['upl']['name'])){

例如：

if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/nameOfTheFile.jpg')){

Answer 3

您可以在调用函数move_uploaded_file中添加自定义文件名。等，

 if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/'.'yourcustomname'.$extension )){

如果您想添加唯一名称，则可以使用like，

if(move_uploaded_file($_FILES['upl']['tmp_name'], 'uploads/'.time().$extension )){
