Question

我尝试通过jquery图片上传器上传文件，但我希望所有文件都使用变量＆＃39; fileName＆＃39;命名上传的文件。因为它目前工作，文件使用其原始名称上传。有什么建议吗？

<?php

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

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

只需更改

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

到

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

PHP Move_Uploaded_Files重命名文件
