我在将电子签名图像上传到用户个人资料时遇到问题，尽管我找不到出错的地方:( 我确实在需要指定的所有其他文件中包含了“签名”......我错过了什么吗？

<?php

if (isset($_GET['success']) === true && empty($_GET['success']) === true) {
    echo 'Your details have been updated!';
}
else {
    if (empty($_POST) === false && empty($errors) === true) {

        $update_data = array(
            'username' => $_POST['username'],
            'fullname' => $_POST['fullname'],
            'email' => $_POST['email'],
            'contact1' => $_POST['contact1'],
            'contact2' => $_POST['contact2'],
            'businessaddress' => $_POST['businessaddress'],

            'allow_email' => ($_POST['allow_email'] == 'on') ? 1 : 0
        );

        update_user($session_user_id, $update_data);

        exit();
    }
    else if (empty($errors) === false) {

您有一个“签名” html 文件字段，并且您正在从 $_POST 读取它，就像它是一个字符串（不是）一样。

PHP 中上传的文件将使用有用的数据填充 $_FILES 以检索文件。

在您的情况下， $_FILES['signature']['tmp_name'] 将是一个字符串，表示文件临时存储的位置。

如果要将文件保存在某处，则必须执行以下操作：

$tmp_name = $_FILES['signature']['tmp_name'];
$path = "/some/path/".$_FILES['signature']['name'];
move_uploaded_file($tmp_name, $path);

而不仅仅是阅读 $_POST['signature'] （顺便说一句，不会设置）。
